Answer:
0.4735
Step-by-step explanation:
10 defective, 62 not defective
P(good) = 62/72 = 31/36
All 5 good:
(31/36)⁵ = 0.4734738145
Answer:
.36
Step-by-step explanation:
4 divided by 11 equals .36 repeating
Answers:
21.75
1.37
10
15
Step-by-step:
Dozen flyers:price
4:7.25
12:x
To solve this mulitply 7.25 by 3 (because this is what we multiplied 4 by to get 12) 7.25*3=21.75
Question 2:
We can write teh following equation
.49+.22(x-1)=price
This is essentially saying that we pay .49 for the first ounce and .22 for every ounce after that
We can plug in an x value to get
.49+.22(5-1)
.49+.22(4)
.49+.88
1.37
Question 3:
We can write the following equation
x+2=y
We need to find out what happens when x=8
8+2=10
Question 4:
We can solve this with ratios
x:y
1.5:4.5
5:x
To solve just multiply 4.5 by 10/3 and get 15
We can just multiply
