A 95% confidence interval for the mean rate is < M

Answers

Answer 1

Using the confidence interval, a 95% confidence interval for the mean rate is (4.4206,4.2106).

In the given question, we have to construct a 95% confidence interval for the mean rate.

There is given  interest rates (annual percentage rates) for a 30-year fixed rate mortgage from a sample of lenders in Macon, Georgia for one day.

It is reasonable to assume that the population is approximately normal.

4.754, 4.375, 4.173, 4.678, 4.425, 4.227, 4.126, 4.250, 3.951, 4.197

We find the mean

Mean=4.754+4.375+4.173+4.678+4.425+4.227+4.126+4.250+3.951+4.197/10

Mean=43.156/10

Mean=4.3156

Standard Deviation(S)=√(x−mean)^2/n−1

S=√(4.754−4.3156)^2/10−1

S=√(0.4384)^2/9

S=√0.1922/9

S=√0.02136

S=0.1462

95%=0.95 confidence interval for z is

Z= [tex]z_{\alpha /2,dt}[/tex]

dt=n−1

dt=10−1

dt=9

[tex]\alpha[/tex] = 1−0.95=0.05

[tex]\alpha /2[/tex]=0.05/2=0.025

Z= [tex]z_{0.025,9}[/tex]

Z= 2.262

Confidence interval

CI=Mean±Z× s/√n

CI=4.3156±2.262× 0.1462/√10

CI=4.3156±2.262× 0.1462/3.1623

CI=4.3156±2.262×0.0462

CI=4.3156±0.105

CI=(4.3156+0.105),(4.3156−0.105)

CI=(4.4206,4.2106)

Hence, a 95% confidence interval for the mean rate is (4.4206,4.2106).

Find another point on a line that includes the points (-5, 4) and (4, 1).

Answers

The other points (7.3, 2.2) are on a line that includes points (-5, 4) and (4, 1).

What is the equation of a line?

The equation of a line is written as axe + by + c = 0, which is its conventional form. In this equation, the variables x and y are the constant term, while the coefficients a and b are the coefficients. It is a first-order equation with the variables x and y.

Slope using the formula:

[tex]m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

We have two points, (-5, 4) and (4, 1).

m = (1 - 4) ÷ (4 - (-5))

m = −1/3

m = -0.3

Line Equations with Slope : y - y1 = m(x - x1)

Using the coordinates of one of the points on the line, insert the values in the x1 and y1 spots to get an equation of a line in point-slope form.

Let's use a point from the original example above  (4, 1). and the slope we calculated as -0.3. Put those values in the point-slope format to get an equation of that line in the point-slope form:

y - 1 = -0.3(x - 4)

y = -0.3x + 2.2

Using the equation y = -0.3x + 2.2, set x=0 to find the y-intercept.

y = -0.3(0) + 2.2

y = 2.2

The y-intercept is 2.2

Using the equation y = -0.3x + 2.2, set y=0 to find the x-intercept.

0 = 3x - 6

0 = -0.3x + 2.2

0.3x  = 2.2

x = 7.3

The x-intercept is 7.3.

Hence, the other points (7.3, 2.2) are on a line that includes the points (-5, 4) and (4, 1).

M is the midpoint of LN. What is LM? Also what is LN?

Answers

Using the given information, the length of LM is and the length of LN is 12

Calculating length

From the question, we are to determine the length of LM and LN.

From the given information,

M is the midpoint of LN

Therefore,

LM = MN

Also,

From the given information,

LM = 3x

MN = 2x + 2

Thus,

3x = 2x + 2

Solving for x

3x = 2x + 2

3x - 2x = 2

x = 2

Then,

Substitute the value of x in the equation

LM = 3x

LM = 3(2)

LM = 6

Also,

LN = LM + MN

LN = 3x + 2x + 2

LN = 5x + 2

Substitute the value of x

LN = 5(2) + 2

LN = 10 + 2

LN = 12

Hence, the value of LM is 6 and the value of LN is 12

Answers

The probabilities, using the normal distribution, are given as follows:

a. P(0 < x < 0.5) = 0.1915.

b. P(-1.42 < x < 0) = 0.4222.

c. P(x > 0.46) = 0.3228.

d. P(x > -0.5) = 0.6915.

e. P(x < 2.05) = 0.9798.

f. P(x < -0.70) = 0.2420.

Normal Probability Distribution

The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.

For a standard normal random variable, the mean and the standard deviation are given as follows:

[tex]\mu = 0, \sigma = 1[/tex]

Hence each value of x is it's own z-score.

For item a, the probability is the p-value of Z = 0.5 subtracted by the p-value of Z = 0, hence:

P(0 < x < 0.5) = 0.6915 - 0.5 = 0.1915.

For item b, the probability is the p-value of Z = 0 subtracted by the p-value of Z = -1.42, hence:

P(-1.42 < x < 0) = 0.5 - 0.0778 = 0.4222.

For item c, the probability is one subtracted by the p-value of Z = 0.46, hence:

P(x > 0.46) = 1 - 0.6772 = 0.3228.

For item d, the probability is one subtracted by the p-value of Z = -0.5, hence:

P(x > -0.5) = 1 - 0.3085 = 0.6915.

For item e, the probability is the p-value of Z = 2.05, hence:

P(x < 2.05) = 0.9798.

For item f, the probability is the p-value of Z = -0.70, hence:

P(x < -0.70) = 0.2420.

Answer:

Slope = 1/3

Y-intercept = 0

Step-by-step explanation:

Hello!

Slope - Intercept Form: y = mx + b

m = slopeb = y-intercept

The slope is the coefficient before the x-variable. Which means that the slope would be 1/3.

The y-intercept is the constant term after the x-term. In this case, there is no term, so the y-intercept is 0.

Answer:

Slope: 1/3

y-intercept: 0

Step-by-step explanation:

y=mx+b

the coefficient (m) of x is always the slope, so therefore the slope is 1/3

What is are Right Angled Triangle?

According to the definition of a right triangle, if one of the triangle's angles is a right angle (90°), the triangle is referred to as a right-angled triangle or just a right triangle. Triangle ABC is a right triangle in the example image, and its components are the base, altitude, and hypotenuse. Here, the base is represented by AB, the altitude by AC, and the hypotenuse by BC. The largest side and side opposite to the right angle of a right triangle, the hypotenuse, is the side that needs to be considered.

The sum of any two sides of a triangle's three sides is always more than the sum of its third side, making it a regular polygon. A triangle only possesses this quality.

In the figure

From Pythagoras' theorem, we have, h² = p²+b²

Now we can write 3 equations from the figure i.e

m²=7²+n²

m²=35²-x²

x²=n²+28²

So we have m²=35²-n²-28²

⇒m²=35²-28²-m²+7²

⇒2m²=35²-28²+7²

⇒2m²= 490

⇒m²= 490/2

⇒m= 7√5

Hence, the value of m in the figure is 7√5

A translation is a movement in a straight line.

In order to determine the component form of the vector that translates C to D, we have to subtract the coordinate values of point C from the coordinate values of the image C:  

(x, y) = D - C  

The movement from C to D on the x-axis is 7 units to the right (positive 7) while movement on the y-axis is 3 units down (negative -3). Thus:

(x, y)  = (7, -3)

In vector form, <x, y> = <7, -3>

Answers

Step-by-step explanation:

secx - 2=0

secx= 2

x= π/3

that's it

The x-values that satisfy the equation Sec(x) - 2 = 0 are x = π/3 and x = 5π/3.

To verify the given equation, we need to find the value(s) of x that satisfy the equation Sec(x) - 2 = 0.

Sec(x) represents the secant function, which is the reciprocal of the cosine function.

The equation can be rewritten as follows:

Sec(x) = 2

To find the solutions, we can take the reciprocal of both sides:

1 / Cos(x) = 2

Next, we can invert the equation to get the cosine function alone:

Cos(x) = 1/2

The cosine function has a value of 1/2 at two specific angles in the interval [0, 2π]: π/3 and 5π/3.

These angles correspond to the inverse cosine function (arccos), so we have:

x = arccos(1/2) = π/3 or x = arccos(1/2) + 2π = 5π/3

Therefore, the x-values that satisfy the equation Sec(x) - 2 = 0 are x = π/3 and x = 5π/3.

The length of the fifth rectangular slate is 16 inches. If its length and width are each decreased by 2 inches, the area will be 56 square inches less than the original area. What is the width of the original rectangular slate?

Answers

The width of the original rectangular slate is 14 inches.

What is the width?

A rectangle is an object that has four sides. The opposite sides are of equal length. A rectangle has two diagonals that are of equal length that bisect each other at right angles.

The area of a rectangle = length x width

Area of the new rectangular slate = (16 - 2) x (w - 2) = (16 x w) - 56

Area of the new rectangular slate = 14 x (w - 2) = 16w - 56

Area of the new rectangular slate = 14w - 28 = 16w - 56

In order to determine the value of w, take the following steps:

Combine similar terms together: 56 - 28 = 16w - 14w

Add similar terms together: 28 = 2w

Answers

The measure of angle CDE ( ∠CDE) is 55°. The correct option is the first option  55°

Calculating the measure of the angle formed by two tangents

From the question, we are to determine the measure of angle CDE.

From one of the circle theorems, we have that

"The measure of the angle formed by two tangents that intersect at a point outside a circle is equal to one-half the positive difference of the measures of the intercepted arcs"

Thus,

m ∠CDE = 1/2(measure of arc CBE - measure of arc CE)

From the given information,

Measure of arc CE = 125°

Then,

Measure of arc CBE = 360° - 125°

Measure of arc CBE = 235°

Therefore,

m ∠CDE = 1/2(235° - 125°)

m ∠CDE = 1/2(110°)

m ∠CDE = 55°

An electrician requires 250 energy saving light bulbs. He comes across four suppliers of these light bulbs.
ELECTRA sells the light bulbs at R 123.00 each, with a R 350.00 delivery fee. ZZZ LIGHTING sells the light bulbs at R
140.00 with a 13% discount on the final amount, but with a
R 260.00 delivery fee. SPARX sells the light bulbs at R 255.00 each with a buy one, get one free offer and no delivery fee.
Finally, BRIGHTEX sells the light bulbs at R 190.00 each
with a third off the final amount, and a delivery fee of R 100.00. Which supplier offers the best deal for the electrician?

Answers

Supplier which gives the best deal of selling light bulbs for the electrician is ZZZ LIGHTING with the total selling amount of

$ 30676.2.

As given in the question,

Different suppliers sells energy saving light bulbs with different deals,

Number of bulbs  required by an electrician = 250

Different deals of selling amount are as follow:

1. ELECTRA :

123 (250) + 350

=$31100

2. ZZZ LIGHTING :

140(250) + 260

= $35260

13% discount on final amount

= 13% of 35260

= 4583.8

Total amount to pay = 35260 - 4583.8

                                  = $30676.2

3. SPARX :

Offer of Buy one get one and no delivery fee

Total amount to be pay for 125 light bulbs.

255 (125)

= $31875

4. BRIGHTEX :

190(250) + 100

= $47600

With a third off on the final amount

(1/3) of 47600

= $15866.666..

= $15867 (approximately)

Final payment = 47600 - 15867

                        = $31733

$31875 > $31733 > $31100 >  $30676.2

Therefore, supplier which gives the best deal of selling light bulbs for the electrician is ZZZ LIGHTING with the total selling amount of

$ 30676.2.

The function that can easily be seen when a quadratic function is given

in the form: y = a (x − ℎ)^2 + K are

the vertex of the parabolawhere the axis of symmetry of the parabola liesthe focus of the parabola the direction the curve opens to

How to get the required details

A parabola is given in factored form when it is in the form

y = a (x − ℎ)^2 + K

the factored form can be rearranged

(y - k) = a (x − ℎ)^2

The vertex is v(h, k)

the axis of symmetry of the parabola when the parabola is written in the form as in the question is of the formula x = -b/2a.

this says that the axis of symmetry is a vertical line

the focus is given by f(h, k + 1/4a)

"a" curve opens up when a is positive and down when a is negative. when (x − ℎ) = a (y − k)^2, a opens left or right

How to Interpret a Scatter Plot Diagram?

1) Scatter plots are defined as the graphs that present the particular relationship between two variables in a data-set.

A scatter plot is also defined as a chart type that is usually used to observe and visually display the relationship between variables.

From the given scatter plot, we can say that the scatter plot at the right would most likely be used to represent the number of siblings a person has and the person’s GPA.

2) From the given scatter plot, we can see that the x-axis shows the number of days left since filling up while the y-axis represents the gallons of gas.

Now, we want to find out the most reasonable estimate of the gallons of gas in a tank if it has been 3 days since filling up. We will trace 3 on the x-axis and the corresponding value on the y-axis would be approximately 17 gallons.

Answers

Answer:

y = 6RS = 39ST = 38

Step-by-step explanation:

You have segment RT of length 77 with point S on it dividing it into segments RS=6y+3 and ST=5y+8. You want to know the value of y and the lengths of segments RS and ST.

Segment sum theorem

The segment sum theorem tells you the whole is the sum of the parts:

  RS +ST = RT

  (6y +3) +(5y +8) = 77 . . . . . use given values

Solution

  11y +11 = 77 . . . . . . . . . . . . collect terms

  y +1 = 7 . . . . . . . . . . . . . . . divide by 11

  y = 6 . . . . . . . . . . . . . . . . . subtract 1

The lengths of the parts are ...

  RS = 6y +3 = 6(6) +3 = 39

  ST = 5y +8 = 5(6) +8 = 38
