The guests (g) still need to reply are 16.

What is arithmetic operation?

Arithmetic operation is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots.

Now it is given that,

Number of guests invited = 33

Number of guests replied "will attend" = 8

Number of guests replied "will not attend" = 9

So, total guest replied = 8 + 9

⇒ total guest replied = 17

Thus, the guests (g) still need to reply = 33 - 17

⇒ the guests (g) still need to reply = 16

Thus, the guests (g) still need to reply are 16.

Ellen’s mom thinks the local weather forecaster correctly predicts the weather 85% of the time, but Ellen thinks it is less than that. The 95% confidence interval for the true proportion of correct forecasts by this weather forecaster is (0.796, 0.862). Is it reasonable to believe the true proportion of times this weather forecaster correctly predicts the weather is less than 85%? Yes, because most of the values in the interval are below 0.85. Yes, because the center of the interval is 0.829, which is less than 0.85. No, because 0.85 is in the interval. No, because there are values in the interval that are greater than 0.85.

A real-world problem with a sample and a population is modeled by the proportion 66/100=x/2,500. Use the proportion to complete the sentences.

Answers

Answer:

x = 1,650

Step-by-step explanation:

A real-world problem with a sample and a population is modeled by the proportion 66/100=x/2,500. Use the proportion to complete the sentences.

From the above question, we have to solve for x

Hence, we have the proportion

66/100=x/2,500

Cross Multiply

100 × x = 66 × 2,500

x = 66 × 2,500/100

x = 1,650
