Answer: 0.4
Step-by-step explanation:
We know that the standard deviation of the sampling distribution of mean is given by:-
Given : Standard deviation : 
Sample size : n= 25
Then, the standard deviation of the sampling distribution of mean times will be :-
Hence, the standard deviation of the sampling distribution of mean times=0.4
Answer:
$5.38
Step-by-step explanation:
$13.45 / 5 (To find the value of 1 pound of cheese, Total money spent divided by total pound of cheese bought)
$2.69 (1 pound of cheese will cost)
So, $2.69 x 2 (Multiply by 2 to find how much 2 pound of cheese will cost)
$5.38
Dominic is looking over his spending pattern for the past week to try to determine how much money he had on Sunday. On Monday, his credit is $100. On Wednesday, his credit is $112. On Friday, his debit is $83. On Sunday, his debit and credit are $100 and $62 respectively.
20 percent is 1/5, so we'd multiply 60 by 5.
60x5=300
60 minutes is 20% of 300
1 zero pair of 25 was added to bring given function into vertex form.
<h3>What is a Zero Pair ?</h3>
A zero Pair is the set of two numbers which when added together gives 0.
The function given is
f(x) = x² -10x -4
To convert it into the vertex form
y = a(x-h)² +k
f(x) = x² -10x +25 -25 -4
f(x) = x² -10x +5² -25-4
f(x) = (x-5)² -29
Therefore this is the given function's vertex form and
1 zero pair of 25 was added to bring it into that.
Therefore Option D is the answer.
