Answer:
285 = 50h + 60; 4.5 hours
Step-by-step explanation:
$50 per hour - 50h
$60 for parts - 60
$285 total
285 = 50h + 60
225 = 50h
h = 4.5

Answer: 0.2501
Step-by-step explanation:
Given : The proportion of the bulbs in the lot are defective = 20%= 0.20
Sample size : n =15
Let x be the binomial variable that represents the defective bulbs.
Binomial probability formula :
The probability that exactly 3 bulbs from the sample are defective : P(X=3)
Required probability = 0.2501
Hey!
---------------------------------------------
Solution:
Find the Highest Common Factor of 8, 12, and 20.
Highest Common Factor = 4
Divide.
8 / 4 = 2
12 / 4 = 3
20 / 4 = 5
4 symbolizes the amount of baskets there are.
---------------------------------------------
Answer:
2 banana's per basket.
3 apple's per basket.
5 orange's per basket.
---------------------------------------------
There is no possible way that there can be the same amount of fruit in each basket.

Hope This Helped! Good Luck!
I'm on a phone right now so I may mess up.
In this question you have to take advantage of corresponding parts. You can find the angle beside the 65 degree angle by doing 180-65=115. Using your understanding of corresponding parts you can now conclude that 55+x=115. Now you just do the algebra and you get x=60
