do you know how to find the area of a normal shape?

You can split this shape into 2 rectangles if you draw a horizontal line between the bigger and smaller rectangle.
The top half
LxW=A
5x7=35
The top half's area is 35.
The bottom Half
LxW=A
10x8=80
Now, add these 2 areas together and that is your answer.
Your answer is 115 cm^2

Solve the following system of equations using elimination (addition)5x - 6y = - 32

3x + 6y = 48

Answers

Answer:

x = 2

y = 6 1/3

Step-by-step explanation:

5x - 6y = -32

3x + 6y = 48

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

8x = 16

x = 2

5(2) - 6y = 48

10 - 6y = 48

-6y = 48 - 10

-6y = 38

y = 6 1/3

Which of the following conditions must be met if you want to use a z-procedure to construct a confidence interval for a population proportion? A) The sample size must be small. B) The population standard deviation must be known. C) The population must be normally distributed. D) The sample must be random and sufficiently large.

Answers

To use a z-procedure to construct a confidence interval for a population proportion, the following conditions must be met:

D) The sample must be random and sufficiently large.

This means that the sample should be selected in a way that each individual has an equal chance of being included. Additionally, the sample size should be sufficiently large to ensure that the normal approximation for the sampling distribution of the sample proportion is valid.

It's important to have a random sample because it helps to ensure that the sample is representative of the population, making the results more reliable and generalizable.

As for the sample size, it should be large enough to satisfy the condition of having at least 10 successes and 10 failures. This ensures that the normal approximation can be applied.

The other answer choices, A) The sample size must be small, B) The population standard deviation must be known, and C) The population must be normally distributed, are incorrect and do not apply to the conditions for using a z-procedure to construct a confidence interval for a population proportion.

By meeting the conditions of having a random and sufficiently large sample, you can use a z-procedure to construct a confidence interval for a population proportion.Answer:
