Jake's water bill is $24.40 per month plus $2.20 per ccf (hundred cubic feet) of water. What is the maximum number of ccf Jake c

siniylev [52]

Answer:the maximum number of ccf Jake can use if he wants his bill to be no more than $58.00 is $15.3

Step-by-step explanation:

Let x represent the number of ccf of water that Jake uses in a month.

Jake's water bill is $24.40 per month plus $2.20 per ccf (hundred cubic feet) of water. This means that if she uses x ccf of water in a month, her total water bill would be

24.40 + 2.2x

Therefore, the maximum number of ccf Jake can use if he wants his bill to be no more than $58.00 would be

24.40 + 2.2x ≤ 58

2.2x ≤ 58 - 24.4

2.2x ≤ 33.6

x ≤ 33.6/2.2

x ≤ 15.3

Harlamova29_29 [7]

Answer:

Mean track length for this rock specimen is between 10.463 and 13.537

Step-by-step explanation:

99% confidence interval for the mean track length for rock specimen can be calculated using the formula:

M± $\frac{t*s}{\sqrt{N}}$ where

M is the average track length (12 μm) in the report
t is the two tailed t-score in 99% confidence interval (2.977)
s is the standard deviation of track lengths in the report (2 μm)
N is the total number of tracks (15)

putting these numbers in the formula, we get confidence interval in 99% confidence as:

12± $\frac{2.977*2}{\sqrt{15}}$ =12±1.537

Therefore, mean track length for this rock specimen is between 10.463 and 13.537
