Answer:

see below

Step-by-step explanation:

7,12,16,20,27,40,56,64

The square numbers are 16 = 4^2   and 64 = 8^2

The difference is 64 - 16 =48

The cube numbers are 27 = 3^3 and 64 = 4^3

64 - 27 =37

Answer:

a. 48

b. 37

Step-by-step explanation:

7,12,16,20,27,40,56,64

Square numbers= 16=4², 64=8²

  • the difference= 64-16= 48

Cube numbers= 27=3³, 64=4³

  • the difference= 64-27= 37

Suppose a circle has a radius of 13 inches. How far would a 24 inch chord be from the center of the circle? (Hint: Draw a diagra
lys-0071 [83]

Answer:

Step-by-step explanation:

Directions

  • Draw a circle
  • Dear a chord with a length of 24 inside the circle. You just have to label it as 24
  • Draw a radius that is perpendicular and a bisector through the chord
  • Draw a radius that is from the center of the circle to one end of the chord.
  • Label where the perpendicular radius to the chord intersect. Call it E.
  • You should get something that looks like  the diagram below. The only thing you have to do is put in the point E which is the midpoint of CB.

Givens

AC = 13 inches                   Given

CB = 24 inches                  Given

CE = 12 inches                    Construction and property of a midpoint.

So what we have now is a right triangle (ACE) with the right angle at E.

What we seek is AE

Formula

AC^2 = CE^2 + AE^2

13^2 = 12^2 + AE^2

169 = 144 + AE^2                     Subtract 144 from both sides.

169 - 144 = 144-144 + AE^2     Combine

25 = AE^2                                Take the square root of both sides

√25 = √AE^2

5 = AE

Answer

The 24 inch chord is 5 inches from the center of the circle.

Let mu denote the true average number of minutes of a television commercial. Suppose the hypothesis H0: mu = 2.1 versus Ha: mu &
natka813 [3]

Answer:

A. T > 2.539

Step-by-step explanation:

We have a hypothesis test of the mean, with unknown population standard deviation.

The hypothesis are:

H_0: \mu = 2.1 \\\\H_a: \mu > 2.1

From the hypothesis we can see that the test is right-tailed, so the critical value of t should be a positive value.

The degrees of freedom can be calculated as:

df=n-1=20-1=19

The significance level is 0.01, so the critical value tc should be the one that satisfies:

P(t>t_c)=0.01

Looking up in a t-table, for 19 degrees of freedom, this critical value is tc=2.539.

Please help with HW. I will give brainliest.
sammy [17]

Answer:

for page 1, the answer is  y = x + 1

for page 2, the answer is linear

Step-by-step explanation:

Why is it y = x + 1?

It is y = x + 1 because if you look at the steps, all of them are reasonable for having a multiplication equation. Step 1 has a equation of 1 x 1, step 2 has an equation of 2 x 2, and  step 3 has an equation of 3 x 3. So the relationship would be adding +1 to every step and count up from 1 - 3.

--------------------------------------------------------------------------------------------------------------

Why is it linear?

It's linear cause the relationship between x and y is called a linear relationship because the points so plotted all lie on a single straight line.
