Can someone pls help me with question 7 :(<br> Ignore above text x
cricket20 [7]

Answer: x= 30 because the elevated point is 25 degrees and if you add it with 110 and subtract it with 35 you get 110 + 25 = 135 and 35 - 25 = 15 135 + 15 = 150 and 180 - 150 = 30. so it is 30 degrees. (tell me if i was wrong cause i'm 90% sure this is it but i don't know.)

Suppose that the ages of members in a large billiards league have a known standard deviation of σ = 12 σ=12sigma, equals, 12 yea
asambeis [7]

Answer:

n\geq 23

Step-by-step explanation:

-For a known standard deviation, the sample size for a desired margin of error is calculated using the formula:

n\geq (\frac{z\sigma}{ME})^2

Where:

  • \sigma is the standard deviation
  • ME is the desired margin of error.

We substitute our given values to calculate the sample size:

n\geq (\frac{z\sigma}{ME})^2\\\\\geq (\frac{1.96\times 12}{5})^2\\\\\geq 22.13\approx23

Hence, the smallest desired sample size is 23
