Step-by-step explanation:

(I'm a visual learner so I'll have a picture of my work as well)

okay, you're going to want to separate this into a large rectangle and a triangle.

From there you're going to calculate the area of both.

rectangle formula:

A= L*H

Triangle Formula:

A= (L*H)/2

Then you just plug in the numbers and calculate, getting 18 for the rectangle and 16 for the triangle. 18+16 = 34

You add the two areas together as shown above, and then you have your area for the whole shape!

Answer: $6, 720

Step-by-step explanation:

Formular for simple interest =P×R×T

where;

P= 6000

R= 3% = 0.03

T= 4 years

$6000 × 0.03 × 4

= $720

The total amount to be paid back at the end of time will be

$6,000 + $720

=$6, 720

I hope this helps

Find value of x<br> A.)46<br> B.)80<br> C.)15<br> D.) 26

Gwar [14]

The two angles are supplementary angles, which when added together equal 180 degrees.

6x -10 + 6x +10 = 180

Combine like terms:

12x = 180

Divide both sides by 12:

x = 180/12

x = 15

The answer is C) 15

Answer:

P-value = 0.0367

Step-by-step explanation:

This is a hypothesis test for a proportion.

The claim is that the percentage of residents who favor construction is significantly over 42%.

Then, the null and alternative hypothesis are:

$H_0: \pi=0.42\\\\H_a:\pi>0.42$

The sample has a size n=900.

The sample proportion is p=0.45.

The standard error of the proportion is:

$\sigma_p=\sqrt{\dfrac{\pi(1-\pi)}{n}}=\sqrt{\dfrac{0.42*0.58}{900}}\\\\\\ \sigma_p=\sqrt{0.000271}=0.016$

Then, we can calculate the z-statistic as:

$z=\dfrac{p-\pi-0.5/n}{\sigma_p}=\dfrac{0.45-0.42-0.5/900}{0.016}=\dfrac{0.029}{0.016}=1.79$

This test is a right-tailed test, so the P-value for this test is calculated as:

$\text{P-value}=P(z>1.79)=0.0367$
