We take 8 and multiply it by sqrt(2) , so diagonal is 11.3
Answer: 1.4862
Step-by-step explanation: To find 6% of 24.77, first write 6% as a decimal by moving the decimal point two places to the left to get 0.06.
Next, the word "of" means multiply so we will multiply 0.06 by 24.77.
(0.06) (24.77) = 1.4682
Therefore, 6% of 24,77 is 1.4862.
Answer:
x = 0
Step-by-step explanation:
The idea of this equation is to isolate X. But first we have to make all the operations that we can resolve before resolving it.
The first step is to resolve the multiplications. In this case we use distributive property, multiplying each term by the other one.
We do the same on the other side of the equation:
Then we have:
All the factors that contain X go to the left and the ones that don't have it to the right:
Answer:
to
Step-by-step explanation:
Given :The owner of a restaurant is reviewing customer complaints. In a random sample of 227 complaints, 57 complaints were about the slow speed of the service.
To Find :Create a 95% confidence interval for the proportion of complaints that were about the slow speed of the service.
Solution:
n = 227
x = 57
Formula of confidence for proportion: to
z at 95% is 1.96
Substitute the values in the formula :
Confidence for proportion: to
Confidence for proportion: to
Hence 95% confidence interval for the proportion of complaints that were about the slow speed of the service is to
