A
Step-by-step explanation:
To write the coefficients of the 8 terms, either start with a combination of 7 things taken 0 at a time and continue to 7 things taken 7 at a time or use the 7th row of Pascal’s triangle.
For the first term, write x to the 7th power and 3 to the 0 power. Then decrease the power on x and increase the power on y until you reach x to the 0 and y to the 7.
Simplify by evaluating the coefficients and powers of 3.
Answer:
3.45 times
Step-by-step explanation:
530.93/153.94 = 3.4489411459
Answer:
d. The histogram would be approximately bell-shaped, and the normal quantile plot would have data points have follow a straight-line pattern.
Step-by-step explanation:
Since the variable is normally distributed, the histogram of women's height should be approximately bell shaped (if the data was obtained form a random sample).
Again, the variable is normally distributed, therefore, the quantile plot should follow a straight line pattern (a diagonal line to be more precise).
First, change the fraction (decimal and percent) into gallon
Martha used 17% of the total oil, that means
Martha = 17% × 8 gallons
Martha = 0.17 × 8 gallons
Martha = 1.36 gallons
Brett used 0.18 of the total oil
Brett = 0.18 × 8 gallons
Brett = 1.44 gallons
Mike used 0.7 gallons
Second, compare the number of gallon they used
1.36
1 acts as ones
3 acts as tenths
6 acts as hundreths
1.44
1 acts as ones
4 acts as tenths
4 acts as hundreths
0.7 or 0.70
0 acts as ones
7 acts as tenths
0 acts as hundreths
Compare the ones, 1.44 and 1.36 both have 1 as the ones, however 0.7 has 0 as ones. Because 1 is greater than 0, 1.44 and 1.36 are greater than 0.7.
Now compare the tenth, 1.44 has 4 as the tenths, and 1.36 has 3 as the tenths. Because 4 is greater than 3, 1.44 is greater than 1.36.
1.44 > 1.36 > 0.7
Brett > Martha > Mike
Brett used the greatest amount of oil
