Answer:
m<U=60°
Step-by-step explanation:

Answer:
50%, 68.26%, 95.54%
Step-by-step explanation:
Let X be the day care costs
X is N(10000, 2000)
Since normal distribution is symmetrical about the mean we get
above 10000, exactly 50% of day care cost would be .
Between 8000 and 12000,
=
Between 6000 and 14000
%
1)
34a = 14
a = 14 ÷ 34
a = 7/17
2)
<span>-29 = -32m
-32m = -29
m = 29/32

Answer:
6 hours
Step-by-step explanation:
Let the labor hours be x.
The bill comprises of parts cost plus labor cost. Labor cost is hours times the cost per hour. Then we have equation:
- 265 + 48x = 553
- 48x = 553 - 265
- 48x = 288
- x = 288/48
- x= 6
So the answer is 6 hours.
