Answer:
Its 20
Step-by-step explanation:
if we re write it it would be. 40-5 4. and 5 x4 is 20 and 40 minus 20 is 20
Using the principle of proportional relationship, the 42 L of gas can go for a further 165 km
<u>Consumption rate = 8L for 100 km </u>
Km per Litre :
8L = 100km
1 L = m
8m = 100
m = (100 ÷ 8)
= 12.5 kilometer per Litre
<u>Number of kilometers for 42 L </u>
12.5 km = 1 L
m = 42 L
Cross multiply
m = 12.5 × 42
m = 525 km
The difference in the distance = 525 - 360 = 165 km
Therefore, the gas can go for a further 165 km

Answer:
The probability that a randomly selected compact car gets at least 40 miles per gallon is about 1.74%
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
The probability that a randomly selected compact car gets at least 40 miles per gallon is about?
This is 1 subtracted by the pvalue of Z when X = 40. So
has a pvalue of 0.9826
1 - 0.9826 = 0.0174
The probability that a randomly selected compact car gets at least 40 miles per gallon is about 1.74%
