Bill and Pete shared 1/2 of a cake. Bill got to eat twice as much cake as Pete. What fraction of the whole cake did Bill eat?

KatRina [158]

Answer:

Step-by-step explanation:

Total cake shared=1/2

Pete share=x

Bill= twice as much as Pete

=2x

Pete's share+ Bill's share=total share

x+2x=1/2

3x=1/2

x=1/2÷3

x=1/2×1/3

=1/6

Pete's share=x=1/6

Bill's share=2x

=2(1/6)

=2/6

=1/3

The tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000

valina [46]

Answer: 61,750 miles

Step-by-step explanation:

Given : The p-value of the tires to outlast the warranty = 0.96

The probability that corresponds to 0.96 from a Normal distribution table is 1.75.

Mean : $\mu=60,000\text{ miles}$

Standard deviation : $\sigma=1000\text{ miles}$

The formula for z-score is given by : -

$z=\dfrac{x-\mu}{\sigma}\\\\\Rightarrow\ 1.75=\dfrac{x-60000}{1000}\\\\\Rightarrow\ x-60000=1750\\\\\Rightarrow\ x=61750$

Hence, the tread life of tire should be 61,750 miles if they want 96% of the tires to outlast the warranty.

7b + 3 – 4b = 3 – 3(b + 4)

svlad2 [7]

Hello from MrBillDoesMath!

Answer: b

Discussion:

7b + 3 - 4b = 3 - 3(b+4) =>

7b + 3 - 4b = 3 - 3b -12 =>

(7b - 4b) + 3 = -3b - 9 =>

3b + 3 = -3b -9 => Add 9 to both sides

3b + 12 = -3b -9 + 9 =>

3b + 12 = -3b => ( add 3b to both sides)

6b + 12 = 0 => (subtract 12 from both sides)

6b = -12 =>

b = -12/6 = -2

Thank you,

MrB
