1)Which is the most accurate way to estimate 74% of 89?

Answer:

There are no real factors for this.

Step-by-step explanation:

We could answer this either by checking each listed expression to see whether it is a factor of 9r^2-4r+1, or

We could take the coefficients of 9r^2-4r+1, determine the quantity b²-4ac (called the 'discriminant') and draw a conclusion based upon whether the discriminant is -, + or 0.

Let's use the 2nd approach.

Here, a = 9, b = -4 and c = 1.

Then the discriminant is b²2 - 4ac, or (-4)² - 4(9)(1), or 16 - 36.

Since 16 - 36 is negative, we conclude that this 9r^2 - 4r + 1 has NO REAL FACTORS.

Hope it was helpful , good luck ^.^

Answer:

1.) the range is 42

2.) mean: 69.4, median:63, mode:none

3.) none since they are numbers that can be high but not low.

4.)The outlier is a greater number like the mean is 69 and the median is 63 which is halfway between 63 and 64 it will affect more the mean than the median since it doesn't matter the actual value of the outlier. it just depends on what the outlier is.

5.) the measure of central tendency best describes the set data with the outlier to which there is no outlier.

Step-by-step explanation:

Answer:

r = 4.5%

Step-by-step explanation:

I = Prt

$63 = $700 x r x 2

$63 = 1400r

r = 0.045

r = 4.5%

Answer:

area 12.566

circumference 12.566

Step-by-step explanation:

Answer:

Circumference= 6.28 meters

Area=12.56 in²

Step-by-step explanation:

[tex]C=r*pi[/tex]

[tex]C=2*3.14[/tex]

[tex]C=6.28[/tex]

[tex]A=pi*r^2[/tex]

[tex]A=3.14*4[/tex]

[tex]A=12.56[/tex]

Answer:

BE=24

Angle EBC=33

Step-by-step explanation:

Rectangle diagonals are congruent so

[tex]3x + 6 = 6x - 12[/tex]

[tex]3x + 18 = 6x[/tex]

[tex]18 = 3x[/tex]

[tex]x = 6[/tex]

Plug that in one of the equations.

[tex]3(6) + 6 = 24[/tex]

BE=24.

ECD is apart of Isoceles triangle EDC.

Another isoceles triangle is EAB.

They triangle share two sides( remeber all diag ki bals in a rectangle are congruent) and a angle E, so they are congruent triangles.

That means Angle EBA measures 57 degrees.

Angle EBC and Angle EBA add up to 90 degrees so

Angle EBC=33

Answer: I’m pretty sure that BD should also be 150

Step-by-step explanation:

The measure of angle O is 75 because the angle is always half of the arc, so knowing that, and also cd and abs are congruent, the other side of o is probably the same as the other, so it’d be 75, multiply by 2 and itll be 150.

Answer: A

Step-by-step explanation:

We have to find the perimeter of the figure.

For doing so, we have to find the length of all the sides of a quadrilateral

The length of a line segment joining points (x1,y1) and (x2,y2) is given by the distance formula:  

after finding length of all the sides, we add the length of each side to get the perimeter.

Use the distance formula to find the length of each side, and then add the lengths.

São eles: (3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17), (9, 40, 41), (11, 60, 61), (12, 35, 37), (13, 84, 85), (16, 63, 65), (20, 21, 29)

Answer:

2

Step-by-step explanation:

The given angle is 45 degrees so the triangle has the same legs.

we can find the hypotenuse by using the Pythagorean theorem

y= √2(√2)^2 = √4 = 2

Answer: 336 hr

Step-by-step explanation:

Given

The speed of the van is 45 mph

The speed of the family car is 60 mph

distance traveled by van in 112 hours is

[tex]d_1=45\times 112=5040\ miles[/tex]

After 112 hours family car started its Journey. Suppose, van travels another x miles after the family car started its Journey

So, distance traveled by the family car in 't' hours

[tex]\Rightarrow 60\times t=112\times 45+45\times t\\\\\Rightarrow 15 t=5040\\\\\Rightarrow t=\dfrac{5040}{15}=336\ hr[/tex]

So, after traveling 336 hr, the family car will catch the van

Answer:

[tex]\boxed {\boxed {\sf 32+8k}}[/tex]

Step-by-step explanation:

We are given the expression:

[tex]8(4+k)[/tex]

To solve, distribute the 8. Multiply each term inside the parentheses by 8.

[tex](8*4)+ (8*k) \\ (32)+(8k) \\32+8k[/tex]

The expression is equal to 32+8k
