Let y represent the number of feet and x represent the number of minutes. Convert 22 1/2 to decimal form: 22.5
y = -22.5x
Plug in -315 for y
-315 = -22.5x
divide both sides by -22.5
14 = x
It will take 14 minutes.
Answer:
Step-by-step explanation:
in complementary angles sum of two angles is always 90 degree .
2x+18+6x-8=90
8x+10=90
8x=90-10
x=80/8
x=10
angle B=6x-8
=6*10-8
=60-8
=52 degree
therefore angle B is 52 degree
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).
Answer:
Step-by-step explanation:
Yes
29990
10%=29990/10=2999
1%=2999/10=299.90
0.5%=299.90/2=149.95
6%=299.90x6=1799.40
6.5%=1799.50+149.95=$1949.35 tax
total +tax
29990+1949.35=$31395.35
