Answer:
24501.42 cubic meters
Step-by-step explanation:
Volume of a cylinder
= pi r^2 h
Given diameter = 34
radius r = diameter/2
= 34/2 = 17
So radius r = 17
Height h = 27
Pi = 3.14
Volume = 3.14 x (17)^2 x 27
= 3.14 x 17 x17 x 27
Multiply through
= 24501.42 cubic meters
Find the least common multiple of 3 and 5:
3: 3,6, 9,12,15,18,21
5: 5, 10, 15, 20
The least common multiple is 15. This means every 15 days they will be the same day.
Add 15 days to May 5:
5 + 15 = 20
The next day would be May 20
Answer:
$4.29
Step-by-step explanation:
An easy way to do this is to move the decimal point to the left one space.
So 42.87 would become 4.287
But since we are talking about currency, we only want two numbers to the right of the decimal point: 4.28.
And since we are rounding to the nearest cent, the 7 on the end means we round up by 1, making the final answer 4.29!
Answer:
The correct option is B) 0.0228
Step-by-step explanation:
Consider the provided information.
The manager of a grocery store has taken a random sample of 100 customers. The average length of time it took the customers in the sample to check out was 3.1 minutes. The population standard deviation is known to be 0.5 minute.
Thus, the value of n = 100, 
and σ = 0.5
We want to test to determine whether or not the mean waiting time of all customers is significantly more than 3 minutes.
The null and alternative hypotheses are,
and 
Compute the test statistic 
By using the table.
P value = P(Z>2) = 0.0228
Hence, the correct option is B) 0.0228
Answer:
n= 3/5
Step-by-step explanation:
This can be easily done by cross-multiplying(and also beneficial to get rid of fractions):
(5n+1)(2) = 1(8)
10n +2 = 8
10n = 8-2
10n=6
n = 6/10
Simplify:
n = 3/5
Hope this helps!
