9: 8 = 9+8 = 17

136/17 = 8

8 * 9 = 72 / 2 = 36

8*8 = 64 / 2 = 32

32 +32 + 36 + 36 = 136

 the rectangle is 36 x 32

Select the postulate of equality or inequality that is illustrated.
Tcecarenko [31]

Answer: B) Comparison Postulate

This is the idea where if we had two numbers A and B, then we have the three possibilities

  • A < B
  • A = B
  • A > B

We can only pick one item that is true at a time.

In this case, 3+2 simplifies to 5, so 3+2 = 5 is true while 3+2 > 5 is not true.

3+2 > 5 simplifies to 5 > 5, and there's no way a number is larger than itself.

a senator wishes to estimate the proportion of united states voters who favor new road construction. what size sample should be
Nitella [24]

The  size of the sample should be obtained at 2401 in order to be 95% confident

Given that:

Margi of error, ME=0.02

Population proportion, p=0.50

To Find: The size of the sample that should be obtained in order to be 95% confident

Let the size of the sample be n

Using formula,

n=(p*(1-p))*(z(0.05/2)/ME)^{2} \\n=(0.5*(1-0.5))*(1.96/0.02)^{2} \\n=0.25*9604\\n=2401

Therefore, the size of the sample should be obtained at 2401 in order to be 95% confident

The measure of central angle XYZ is StartFraction 3 pi Over 4 EndFraction radians. What is the area of the shaded sector? 32Pi u
Tems11 [23]

Answer:

<em>96π units²</em>

Step-by-step explanation:

Find the diagram attached

Area of a sector is expressed as;

Area of a sector = θ/2π * πr²

Given

θ = 3π/4

r = 16

Substitute into the formula

area of the sector = (3π/4)/2π * π(16)²

area of the sector = 3π/8π * 256π

area of the sector = 3/8 * 256π

area of the sector = 3 * 32π

<em>area of the sector =96π units²</em>
