A random number generator picks a number from 7 to 69 in a uniform manner. Round answers to 4 decimal places when possible.

Find the maximum for the lower quartile

(100PTS)

Answers

Answer 1

Answer:

The lower quartile corresponds to the 25th percentile of the data set. To find the maximum value for the lower quartile, we need to find the largest number that is at or below the 25th percentile.

The range of the numbers that the random number generator can pick is 69 - 7 + 1 = 63. The 25th percentile corresponds to the value that is 25% of the way through this range, which is:

0.25 * 63 = 15.75

Since we can't pick a fractional number, we need to round down to 15. Therefore, the maximum value for the lower quartile is 15.

The congruency rules which satisfy the given triangles are (B) AAS and (D) HA.

What is triangle congruency?

Triangle congruence: If all three corresponding sides and all three corresponding angles are equal in size, two triangles are said to be congruent.

Slide, twist, flip, and turn these triangles to create an identical appearance.

If two triangles meet all 5 requirements for congruence, then they are congruent.

They are right angle-hypotenuse-side (RAHS), angle-side-angle (ASA), angle-angle-side (AAS), side-side-side (SSS), and side-angle-side (SSS). (RHS).

So, according to the given, we can observe that:

2 pairs of angles are congruent one pair of which is 90°.

And 1 pair of sides are congruent.

Then, the rules that satisfy here will be:

AAS and HA

Therefore, the congruency rules which satisfy the given triangles are (B) AAS and (D) HA.

Answer:

554.76 miles per hour

Step-by-step explanation:

[tex]\frac{248 meters}{1 second}[/tex] x [tex]\frac{3600 seconds}{1 hour}[/tex] x [tex]\frac{1 mile}{1609.34 meters}[/tex]

= 554.76 miles per hour

Answer:

[tex]\sf 554.76(mi/h).[/tex]

Step-by-step explanation:

1. Write the initial expression.

[tex]\sf \dfrac{248(m)}{s}[/tex]

2. Using conversion factors, convert from meters to miles.

a) First, convert the meters to kilometers.

[tex]\sf 248(m)*\dfrac{1(km)}{1000(m)} =0.248(km)[/tex]

Here, the meters cancel, since one is on the numerator and the other one is expressed as a denominator, and we simpyl multiply the value by the fraction, resulting in a number that would be a value for kilometers.

b) Convert from kilometers to miles.

[tex]\sf 0.248(km)*\dfrac{1(mi)}{1.60934(km)} =0.1541(mi)[/tex]

3. Convert the seconds into hours.

[tex]\sf 1(seconds)*\dfrac{1(hour)}{3600(seconds)} =\frac{1}{3600}(h)[/tex]

4. Rewrite the initial expression using the calculated converted values.

ordered pair described below lie? Explain your answer.
a. (-x, y)
b. (-x, 0)
c. (x, -y)
d. (0. y)

Answers

The quadrant or axis for each of the given ordered pairs is:

a. (-x, y) - second quadrant

b. (-x, 0) - X-axis

c. (x, -y) - fourth quadrant

d. (0, y) - Y-axis

How to determine the quadrants

a. (-x, y):

As the x-coordinate is negative (-x), and the y-coordinate is positive (y), the ordered pair (-x, y) will lie in the second quadrant.

b. (-x, 0):

The x-coordinate being negative (-x), and the y-coordinate 0 renders that the ordered pair (-x, 0) lies on the x-axis. This horizontal axis records an unchanging value for y: zero.

c. (x, -y):

The x-coordinate here is a positive value (x), and the y coordinate a negative one (-y); it implies that the ordered pair (x, -y) lies within the fourth quadrant.  

d. (0, y):

In this case, the x-coordinate is 0 and the y-coordinate is positive (y); therefore, the ordered pair (0, y) has its place on the y-axis. The y-axis is the vertical line on which x retains a permanent numerical value of zero.

The slope of the line is -4, which means that the swimmer will complete 4 laps every minute.  For 5 weeks they have the same amount of money. The direction is 270° clockwise rotation. The pattern of scatter plot is that there is a weak, negative linear association. The measurement of FD = 1.52. The slope of the line is negative three halves. The probability of No Heads is 25%. The scale factor is one half. The correct answers are C), B), A), B), A), D), D) and B).

The slope of the line is the change in y divided by the change in x, which represents the rate of change of the line. In this case, the slope is negative 4, which means that for every minute that passes, the number of laps remaining decreases by 4. So, the swimmer completes 4 laps every minute.

To find the point at which the two savings accounts have the same amount of money, we need to set the two equations equal to each other and solve for x

10x + 25 = 5x + 50

5x = 25

x = 5

So, after 5 weeks, the two siblings will have the same amount of money saved.

The direction of rotation can be determined by looking at the relative positions of the vertices of the original polygon and its image. In this case, the vertices of the image are in quadrant 1, while the vertices of the original polygon are in quadrant 2. This means that the image has been rotated counterclockwise. Additionally, we can see that the image has been rotated by 90 degrees, so the angle of rotation is 90 degrees counterclockwise.

The scatter plot shows a general trend of decreasing cost per cupcake as the number of cupcakes in an order increases. However, there is a fair amount of variability in the data, so the association between the two variables is weak. Additionally, the association is negative, as the cost per cupcake decreases as the number of cupcakes in an order increases.

Similar triangles have proportional side lengths, so we can set up a proportion using corresponding side lengths of the two triangles

AB/DE = BC/EF = CA/FD

Plugging in the known values, we get

11/2.2 = 7.9/EF = 7.6/FD

Solving for FD, we get

FD = (7.6 * 2.2)/11 = 1.52

So, FD has a length of 1.52 units.

The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula

slope = (y2 - y1)/(x2 - x1)

Plugging in the given values, we get

slope = (-10 - (-1))/(3 - (-3)) = -9/6 = -3/2

So, the slope of the line is negative three halves.

The probability of getting no heads in two flips can be found by adding the frequencies of the outcomes where no heads occur (Tails, Tails) and (Tails, Heads) and dividing by the total number of trials

P(No Heads) = (50 + 35)/200 = 85/200 = 0.425 = 42.5%

So, the probability of getting no heads is 42.5%, which is equivalent to 0.425.

Dilations involve multiplying the coordinates of each vertex by a scale factor. To find the scale factor used in this dilation, we can compare the corresponding side lengths of the original triangle and its image. In this case, we can see that the sides of the image are half as long as the corresponding sides of the original triangle. So, the scale factor used to create the image is one half.

Suppose Patrick Goldsmith deposited $1000 in an account that earned simple interest at an annual rate of 10% and left it there for 5 years. At the end of the 5 years, Patrick deposited the entire amount from that account into a new account that earned 10% compounded quarterly. He left the money in this account for 5 years. How much did he have after the 10 years? (Round your answer to the nearest cent.)

Answers

Answer:

Step-by-step explanation:

After 5 years at a simple interest rate of 10%, Patrick would have earned $500 in interest ($1000 x 10% x 5 years). So at the end of the 5 years, he would have $1500 in the account.

If this entire amount is deposited into a new account that earns 10% compounded quarterly, we need to determine the quarterly interest rate first.

The quarterly interest rate is (1 + 0.10/4)^4 - 1 = 0.025 (rounded to three decimal places).

After 10 years (or 40 quarters) at a quarterly interest rate of 0.025, the compounded amount is:

$1500 x (1 + 0.025)^40 = $4045.56

Therefore, Patrick would have $4045.56 in the account after 10 years when rounding to the nearest cent.

Parking lots A and B charge a set fee. A charges 36.50 for 5 hours. B charges 38.00 for 5 hours. Lot A charges 49.50 for 7 hours and lot B charges 50.00 for 7 hours. How many hours are needed to park where it would cost the same?

Answers

Answer:

if you park for 12 hours in both parking lots A and B, it will cost the same amount, which is $64.50.

Step-by-step explanation:

Let's assume that the cost of parking for x hours in both lots is the same, then we can set up the following equations:

For 5 hours of parking:

36.50 = 38.00

This is not true, so we know that the cost for parking in both lots will not be the same for 5 hours.

For 7 hours of parking:

49.50 = 50.00

This is also not true, so we know that the cost for parking in both lots will not be the same for 7 hours either.

Let's try setting up the equation for x hours of parking:

Fee for parking in Lot A = Fee for parking in Lot B

36.50 + (x-5)*7 = 38.00 + (x-5)*7

Simplifying the equation, we get:

36.50 + 7x - 35 = 38.00 + 7x - 35

Solving for x, we get:

x = 12

Therefore, if you park for 12 hours in both parking lots A and B, it will cost the same amount, which is $64.50.

A tennis ball is dropped from a certain height. Its height in feet is given by h(t)=-16t^2+14 where t represents the time in seconds after launch. What is the ball’s initial height?

Answers

The quadratic regression equation is y = -140.61x² + 2,954.23x - 7,512.85 and the ball's initial height is 14 feet.

Writing the quadratic regression equation

Given the set of data

Using a graphing tool, we have

C =  -7,512.85B = 2,954.23A = -140.61

A quadratic regression equation is represented as

y = Ax² + Bx + C

So, we have

y = -140.61x² + 2,954.23x - 7,512.85

When the selling price is 7.75, we have

y = -140.61(7.75)² + 2,954.23(7.75) + -7,512.85

Evaluate

y = 6937

The initial height

The ball's initial height is the height when t = 0, which means we need to evaluate the function h(0).

h(0) = -16(0)^2 + 14

h(0) = 0 + 14

h(0) = 14

Therefore, the ball's initial height is 14 feet.

Answer:

55.5

Step-by-step explanation:

Using the Tangent and Intersected Chord Theorem we know that since the line is tangent to the circle, it will be half of the arc that surrounds the angle. Becuase the arc is 111, dividing it by 2 will give us 55.5

. To determine how funny the jokes were, the researchers asked a group of 86 undergraduates to rate the jokes on a scale from 1 (very unfunny) to 21 (very funny). Participants rated a “lawyer joke” as one of the funniest jokes, with a rating of 14.48 ± 4.38 (M ± SD).
Assuming that these data are normally distributed,
1. What was the rating that marks the cutoff for the top 10% of participant ratings for this joke?

Answers

If the "Lawyer's-Joke" is rates as the funniest, then the rating which is the top 10% of participant rating for this joke is 20 marks.

A "Normal-Distribution" is defined as a probability distribution that is symmetric, bell-shaped, and characterized by its mean and standard deviation.

First, we standardize the rating of 14.48 using the formula:

⇒ z = (x - μ) / σ;

where x is = rating of 14.48, μ is = mean rating, and σ is = standard deviation,

⇒ z = (14.48 - 14.48) / 4.38,

⇒ z = 0,

Next, we take the "z-score" that corresponds to the top 10% of the standard normal distribution.  We know that the "z-score" is approximately 1.28,

Substituting the value in formula,

We get,

⇒ z = (x - μ) / σ   ⇒ 1.28 = (x - 14.48)/4.38,

⇒ x - 14.48 = 1.28 × 4.38,

⇒ x = 20.97 ≈ 20 marks.

Therefore, the rating that marks the cutoff for the top 10% of participant ratings for this joke is approximately 20 on the scale of 1 to 21.

A soccer field is 80 yards wide and 110 yards long. If a person walks across the field along the diagonal instead of walking the length and width of the field, how much shorter is the distance

Answers

So the person would save approximately 244 yards by walking diagonally across the field instead of walking the length and width of the field separately.

what is  approximately  ?

"Approximately" is a word that is used to indicate that a value, quantity, or measurement is close to the actual or precise value, but not exactly the same. It means that the stated value is an estimate or approximation, and may be slightly different from the true value.

In the given question,

Using the Pythagorean theorem, we can find the length of the diagonal of the soccer field:

diagonal² = length² + width²

diagonal² = 110² + 80²

diagonal² = 12,100 + 6,400

diagonal² = 18,500

diagonal = √18,500

diagonal ≈ 136 yards

So the person walking diagonally across the field would cover a distance of approximately 136 yards.

To compare this with the distance they would cover if they walked the length and width of the field separately, we can use the formula for the perimeter of a rectangle:

perimeter = 2(length + width)

perimeter = 2(110 + 80)

perimeter = 2(190)

perimeter = 380 yards

Therefore, if the person walked the length and width of the field separately, they would cover a total distance of 380 yards.

The difference between these two distances is:

380 - 136 = 244 yards

So the person would save approximately 244 yards by walking diagonally across the field instead of walking the length and width of the field separately.

How to draw a quilt of isosceles triangular

Answers

The creation of an isosceles triangle quilt can only be achieved through a number of discreet steps:

The Steps

Initially, select the bespoke size of both individual triangles and the full-scale length and breadth of the snug.

Subsequently, draft a lattice on either a sheet of paper or digital drafting software, with each square serving as a single triangular unit.

Commencing your task from the bottom row, resonate along the equidistant bases while drawing with precision to ensure an immaculate line-up.

Then, for the succeeding section, diverge by slightly altering the position of the point of each triangle in accordance with the intermediary gap that exists between two triangles below it.

Continue repeating this pattern while constructing rows, enveloping further ground until fully complete coverage has been ensured.

Last but not least, rigorously maintain accuracy by exploiting straight edges strategically laid beside precise measuring instruments.

4X Minus 3y Equal 21​

Answers

Step-by-step explanation:

The given equation is:

4x - 3y = 21

To solve for y, we can rearrange the equation as follows:

4x - 21 = 3y

Dividing both sides by 3, we get:

y = (4x - 21) / 3

Therefore, the solution to the equation is:

y = (4x - 21) / 3

Express as a product. 1+2cos a

Answers

Answer:

Therefore, 1 + 2cos a can be expressed as the product of 2 and (cos a/2 + 1).

1 + 2cos a = 2(cos a/2 + 1)

Step-by-step explanation:

We can use the trigonometric identity:

cos 2a = 1 - 2 sin^2 a

to rewrite 1 + 2cos a as:

1 + 2cos a = 1 + 2(1 - sin^2 a/2)

= 1 + 2 - 2(sin^2 a/2)

= 3 - 2(sin^2 a/2)

Now, using another trigonometric identity:

sin a = 2 sin(a/2) cos(a/2)

we can rewrite sin^2 a/2 as:

sin^2 a/2 = (1 - cos a)/2

Substituting this into the expression for 1 + 2cos a, we get:

1 + 2cos a = 3 - 2((1 - cos a)/2)

= 3 - (1 - cos a)

= 2 + cos a

Therefore, 1 + 2cos a can be expressed as the product of 2 and (cos a/2 + 1).

1 + 2cos a = 2(cos a/2 + 1)

Given is a triangle, we need to find the missing lengths and angles,

So,

Using the cosine rule,

b² = a²+c² - 2ac Cosb

b = √4²+7²-2(4)(7)cos35°

b = √16+49-45.87

b = √19.13

b = 4.37

Now, using the sine rule,

Sin C / 7 = Sin 35° / 4.37

C = 11°
