y =
x + 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )

and c = 9, thus
y =
x + 9 ← equation of line
Answer: 554
Step-by-step explanation:
Formula we use to find the sample size :

Given : Standard deviation : 
Margin of error : E=one quarter hour = 0.25 hour
Two-tailed , Critical value use for 0.95 degree of confidence:
i.e. 
Hence, the required sample size = 554
i.e. 554 executives should be surveyed.
3r - 8 = 7 + 8r (make rs on 1 side, numbers on other)
5r = -15(divide by 5 now)
r = -3 (<---Answer)
Hope this helped!
Answer: 4000 cm^3
Step-by-step explanation:
The volume of a rectangular prism is the length*width*height.
We can plug in the values given:
