Step-by-step explanation:
Total number of students=S
Number of girls =G
Number of Boys =G+124
G+G+124 = S
11/20S =G+124, solve for G, S
G=558 - Number of girls.
S =1,240 - Total number of students
1,240 - 558 =682 - Number of boys.
Answer:
Each friend will get 8/5 or 1 4/5 cup of trail mix.
Step-by-step explanation:
The percent is .635% and the fraction form is 127/200
We are given a line with the following data:
r-value = 0.657 (r)
standard deviation of x-coordinates = 2.445 (Sx)
standard deviation of y-coordinates = 9.902 (Sy)
We are asked to find the slope of the line up to 3 decimal places.
To find the slope of the line, based on the data that we have, we can use this formula:
slope, b = r * (Sy / Sx)
substitute the values to the formula:
b = 0.657 * ( 9.902 / 2.445 )
Solve for the b.
Therefore, the slope of the line is
b = 2.66078, round off to three decimal places:
b = 2.661 is the slope of the line.
