Answer:
$50
Step-by-step explanation:
Here's a good formula I use for finding percentages.
4.50÷9x100=50
I had a calculator confirm this. The answer is $50.
And also, thanks so much for 50 points, that's really generous.
It is given in the question that,
The French club is holding a car wash fundraiser. They are going to charge $10 per car, and expect between 50 and 75 cars.
The cost depends on the number of cars washed .
So number of cars is the independent quantity and cost is the dependent quantity .
And here, let, y represents the cost and let x represents the number of cars.
So the domain is 50 to 75 cars.
And when x=50 and 75, value of y is
And the range is $500 to $750 .
So the correct option is B

Answer:
5 * 10^10
Step-by-step explanation:
(9 * 10^10) - (4 * 10^10)
If the * 10^x are both the same then just take the numbers away.
(a)
Q1, the first quartile, 25th percentile, is greater than or equal to 1/4 of the points. It's in the first bar so we can estimate Q1=5. In reality the bar includes values from 0 to 9 or 10 (not clear which) and has around 37% of the points so we might estimate Q1 a bit higher as it's 2/3 of the points, say Q1=7.
The median is bigger than half the points. First bar is 37%, next is 22%, so its about halfway in the second bar, median=15
Third bar is 11%, so 70% so far. Four bar is 5%, so we're at the right end of the fourth bar for Q3, the third quartile, 75th percentile, say Q3=40
b
When the data is heavily skewed left like it is here, the median tends to be lower than the mean. The 5% of the data from 80 to 120 averages around 100 so adds 5 to the mean, and 8% of the data from the 60 to 80 adds another 5.6, 15% of the data from 40 to 60 adds about 7.5, plus the rest, so the mean is gonna be way bigger than the median of around 15.
