Put the number in the formula and do the arithmetic.
C = (5/9)(329 - 32)
C = (5/9)(297)
C = 165
The temperature in °C is 165.
Answer:
Not really 100% sure how to answer this, but if you would like to find the price of any item 10% off, you would just multiply the price by 0.9
EX: item cost $100
$100 x 0.9 = $90
Meaning the price of the item after the discount is applied would be $90
Since were trying to solve for n, you have to isolate it so you would divide both sides by 10, and that will give you n = 4
Answer:
Step-by-step explanation:
A) From the stem-leaf plot, we see that out of 21 tunas, 5 have dangerous levels of copper since the levels go beyond 5.7 parts per million. The required proportion is 5/21=0.2381
B) Given the sample mean is {x}=4.77, sample standard deviation s=1.16 and the sample size is n=21.
Since the population standard deviation is not known, we use t-distribution.
So the 98% CI for mean is
4.77 ± t{1-0.02 /2,20} x 1.16/sqrt(21) = (4.13, 5.41)}
We are sure with 98% confidence the true copper level (in parts per million) lies in the interval (4.13, 5.41)
