Solve the following equation.
U + 2 = 4

Answers

Answer 1

Answer:

U=2

Step-by-step explanation:

This is a simple one-step algebraic equation. In algebra to solve equations, you should use the properties of equality. The properties say that an equation remains true as long as the same thing happens on both sides. For this equation, the property of subtracting should be used; this property states that the same number can be subtracted from both sides. To find U, isolate the variable by subtracting 2 from both sides. This leaves U=2.

Answer 2
U +2= 4
-2 -2
U = 2
2 + 2= 4

The average number of employees that call in sick for the day over the course of a year is 25. The number of employees that call in sick on 12 days are 25, 10, 16, 39, 27, 25, 32, 25, 25, 22, 28 , and 14 Enter the sample mean and the population mean.

Answers

Answer:

it depends on the work place to play it safe i would choose 12

Step-by-step explanation:

The sample mean is equal to 24 and population mean is equal to 25

What is sample mean?

Sample mean represents the measure of the center of the data. The sample mean formula is used to calculate the average value of the given sample data.

Sample mean= sum of the terms/number of the terms

What is population?

The population in static is used for a collection of data. The population mean can be calculated by the sum of all values in the given population divided by a total number of values in the given population.

Population mean= sum of the population/ number of the population

From the given question average of entire year is 25.

According to the population mean formula the sum of the population by number of the population is nothing but the average of the entire year. Thus the population mean is 25.

According to the sample mean formula,

sample mean= sum of the terms / number of the terms

⇒(25+10+16+39+27+25+32+25+25+22+28+14)/12 = 24

Thus the sample mean is equal to 24 and population mean is equal to 25

1/4 is larger than 5/8 by how much?
( fraction)

Answers

Answer:

3/8

Step-by-step explanation:

Step 1: Multiply the denominator and the numerator of 1/4 by 2 to get a common denominator between the two. (1/4 and 5/8 is now 2/8 and 5/8)

1*2= 2; 4*2= 8, so you get 2/8 (which is equal to 1/4)

Step 2: When you get 2/8, subtract:

5/8 - 2/8 = 3/8

And... since 2/8 is equal to 1/4, 3/8 is the answer :)

Hope this helps :)
