Answer:

Second option: 81y^4 - 16x^2, the difference of squares

Step-by-step explanation:

(9y^2-4x)(9y^2+4x) is a special product named difference of squares, then we can apply this formula:

(a-b)(a+b)=a^2-b^2, with a=9y^2 and b=4x, then:

(9y^2-4x)(9y^2+4x)=(9y^2)^2 - (4x)^2

(9y^2-4x)(9y^2+4x)=(9)^2 (y^2)^2 - (4)^2 (x)^2

(9y^2-4x)(9y^2+4x)=81y^(2*2) - 16x^2

(9y^2-4x)(9y^2+4x)=81y^4 - 16x^2

The equation y = 36 + 18x models the relationship
wariber [46]

Answer:

Option B) The height, in inches, of a typical apple tree

Step-by-step explanation:

Let

x----> the number of years, after the tree was planted

y ---> the height in inches, of a typical golden  delicious apple tree

we have

y=36+18x

Remember that

The y-intercept is the value of y when the value of x is equal to zero

In this problem

The y-intercept is the height of the tree when it was planted (x=0)

A researcher conducted a paired sample t-test to determine if advertisements were viewed more in the morning (before noon) or in
Natalija [7]

Answer:

b. No, there was no difference between Morning (M= 32), and Evening (M=40.625), (t [7] = 1.15, p > .05).

Step-by-step explanation:

The critical value for one tailed test is t ∝(7) > 1.895

A one tailed test is performed to test the claim that advertisements were viewed more in the morning (before noon) or in the evening (after 5pm)

The null and alternative hypotheses are

H0: μm = μe   vs     Ha μm > μe

where μm is the mean of the morning and μe is the mean of evening.

The calculated value of t = -1.152587077  which is less than the critical region hence the null hypothesis cannot be rejected .

P(T<=t) one-tail 0.143458126 > 0.05

If two tailed test is performed the critical region is t Critical two-tail 2.364624252

and the calculated t value is  -1.152587077  which again does not lie in the critical region .

Hence μm =  μe or    μm ≤ μe

P(T<=t) two-tail 0.286916252  > 0.025

Therefore

b. No, there was no difference between Morning (M= 32), and Evening (M=40.625), (t [7] = 1.15, p > .05).

Option b gives the best answer.

Plz HELP! WILL GIVE BRAINLIEST!<br><br>1. Consider the picture below. Find the measure of ∠CEA.
pashok25 [27]

Answer:

  103°

Step-by-step explanation:

The marked angles have the same measure, so ...

  14x+7 = 12x +17

  2x = 10 . . . . . subtract 12x+7

  x = 5 . . . . . . . divide by 2

  (14x +7)° = 77°

∠CEA is supplementary to the marked angles:

  ∠CEA = 180° -77°

  ∠CEA = 103°
