X = 1
and = 3
(x,and) = (1,3)
It says The temperature doubled
It means the temperature has been doubled ,
if earlier it was t , then now its 2t
Now in the question it says the the temperature doubled
And now the temperature is 32 degrees ,
so we double it to get the new temperature
and the double of 32 degrees is 64 degrees
So
The value of the expression when t = 32 degrees is 64 degrees
Answer:
3
Step-by-step explanation:
You have to divided by 5 but you will get 2.8. But if you round it it will come out to be 3.
Answer:
The 96% confidence interval for the population proportion of customers satisfied with their new computer is (0.77, 0.83).
Step-by-step explanation:
We have to calculate a 96% confidence interval for the proportion.
We consider the sample size to be the customers that responded the survey (n=800), as we can not assume the answer for the ones that did not answer.
The sample proportion is p=0.8.

The standard error of the proportion is:

The critical z-value for a 96% confidence interval is z=2.054.
The margin of error (MOE) can be calculated as:

Then, the lower and upper bounds of the confidence interval are:

The 96% confidence interval for the population proportion is (0.77, 0.83).
