The computation shows that the amount will be 44.70 Dollars.
<h3>How to illustrate the information?</h3>
The options are missing: Here are the missing options:
A. 44.70 US dollars
B. 73.06 US dollars
C. 136.87 US dollars
D. 140.41 US dollars
For solving this question first we will convert the USD to euros.
The conversion rate we have is:
1 euro = 1.3687 USD
250/1.3687 = 182.655 euros
Now we will subtract it from what he has spent:
= 182.655 - 150
= 32.655 euros
Now we will again convert it back to USD. This will be:
32.655 euros * 1.3687 = 44,695 us dollars
Therefore, the answer is 44.70.

Answer: We are 95% confident that the mean SPF level of sunscreen used by all Cal Poly students is between 29.0813 and 40.0187.
Step-by-step explanation:
Given : Significance level : 
Sample size : n= 52 , which is a large sample (n>30), so we use z-test.
By using z-value table,
Critical value: 
Sample mean : 
Standard deviation : 
The confidence interval for population means is given by :-
i.e. 
Now, the 95% confidence interval for the ppopulation mean = . (29.0813, 40.0187)
Hence, We are 95% confident that the mean SPF level of sunscreen used by all Cal Poly students is between 29.0813 and 40.0187.
Answer:
m = 28
Step-by-step explanation:
Simplifying
0.1(0.5m + 6) = 2
Reorder the terms:
0.1(6 + 0.5m) = 2
(6 * 0.1 + 0.5m * 0.1) = 2
(0.6 + 0.05m) = 2
Solving
0.6 + 0.05m = 2
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-0.6' to each side of the equation.
0.6 + -0.6 + 0.05m = 2 + -0.6
Combine like terms: 0.6 + -0.6 = 0.0
0.0 + 0.05m = 2 + -0.6
0.05m = 2 + -0.6
Combine like terms: 2 + -0.6 = 1.4
0.05m = 1.4
Divide each side by '0.05'.
m = 28
Simplifying
m = 28
Answer:
15$
Step-by-step explanation:
cost of 1 cookie = 10/6
cost of 9 cookies = 9* 10/6 = $15
