5 0

Step-by-step explanation:

U would be {0,1,2,3,4,5,6,7,8,9}

A would be {0,1,2,3,4,5}

and B would be {5,6,7,8,9}

The union would be {0,1,2,3,4,5,6,7,8,9}

And their intersection {5}

A jacket costs $90 at full price. It is on sale for 30% off the regular price. What is the amount of the discount?
Sav [38]
Remember that when you find 30% of the number you have to subtract the 30% from your original $90 because it is 30% off the original price.

pH measurements of a chemical solutions have mean 6.8 with standard deviation 0.02. Assuming all pH measurements of this solutio
aalyn [17]

Answer: 2.14 %

Step-by-step explanation:

Given : pH measurements of a chemical solutions have

Mean :  \mu=6.8

Standard deviation : \sigma=0.02

Let X be the pH reading of a randomly selected customer chemical solution.

We assume  pH measurements of this solution have a nearly symmetric/bell-curve distribution (i.e. normal distribution).

The z-score for the normal distribution is given by :-

z=\dfrac{x-\mu}{\sigma}

For x = 6.74

z=\dfrac{6.74-6.8}{0.02}=-3

For x = 6.76

z=\dfrac{6.76-6.8}{0.02}=-2

The p-value =P(6.74

P(z

In percent, 0.0214\times=2.14\%

Hence, the percent of pH measurements reading below 6.74 OR above 6.76 = 2.14%

One month, Ruby worked 8 hours more than Isaac, and Svetlana worked 4 times as many hours as Ruby. Together they worked 112 hour
melamori03 [73]
R=8+I
S=4R

R+I+S=112
R+R-8+4R=112
6R=120
R=20

So therefore, Ruby worked 20 hours, Svetlana worked 80 hours, and Isaac worked 12 hours.
