Answer:
Center = (10, 5)
Radius = 10
Step-by-step explanation:
Look at the picture
Y = -3
-3 + 3 = 0
It is impossible to divide a number by 0
Answer: The sample should include 542 men and 542 women.
Step-by-step explanation:
When the <em>prior estimate of the population proportion for both population 1 and population 2 are not available</em> , then we assume that it 0.5 i.e. both have equal chances.
Formula to find the equal sample sizes : , where z* = critical z-values associated with the given confidence level and E = Margin of error.
By considering the given information , we have
E= 0.05
Confidence level = 90% =0.90
Critical z-value for 90% confidence level : z*=1.645 (By z-table)
Now, the required sample sizes would be :
Hence, the sample should include 542 men and 542 women.
3 feet... I don’t think the 73 should be square rooted
Answer:
45
Step-by-step explanation:
Because it's face values
If it was place values then it would be 5000 x 90 but since its face values it is 5 x 9 as face values is the number itself
