Answer:
$7.48.
Step-by-step explanation:
We have been given that Chole is buying 2/3 pound of ham and 3/5 as many pounds of cheese as ham.
First of all, we will find pounds of cheese bought by Chole by finding 3/5 of 2/3 as:
We are told that cheese cost $4.95 per pound. Let us find cost of 2/5 pounds of cheese by multiplying 2/5 by $4.95 as:
We are also told that ham cost 5/3 as much per pound as cheese. Let us find cost of per pound of ham by calculating 5/3 of $4.95 as:
Cost of 2/3 pound of ham would be $8.25 times 2/3 as:
Therefore, Chole will pay $7.48 for the cheese and ham.
Answer:
The required amount of mice is 11.82 gram.
Step-by-step explanation:
Given : Assuming that it is known from previous studies that σ = 4.5 grams. If we wish to be 95% confident that the mean weight of the sample will be within 3 grams of the population mean for all mice subjected to this protein diet.
To find : How many mice should be included in our sample?
Solution :
The formula used in the situation is
Where, z value at 95% confidence interval is z=1.96
gram is the mean of the population
gram is the standard deviation of the sample
Substituting the value, to find x sample mean
Therefore, The required amount of mice is 11.82 gram.
Hey there Ag484p1stit,
Answer:
Rent = 25% x $3,400
= $850
Left now = $3,400 - $850
= $2,550
Transportation = 30% x $2,550
= $765.
She spends $765 on transportation.
Hope this helps :D

To get the x-intercepts of the function, f(x) = 4x2 – 24x + 20
It has to be equated to zero and the values of x are the x-intercepts. So,
4x2 – 24x + 20 = 0
The resulting equation is a quadratic equation which can be solved by different methods. The solution is
x = 5, 1
The average therefore is:
(1+5/)2 = 3
Look at step 1, - 6 + 6 = 0
3+6=9
