Answer: Your answer would be 1 2/8 (or 1 1/4):

3 1/8 - 1 7/8

25/8 - 15/8

10/8

1 2/8

You can simplify this further to get 1 1/4. Hope this helps!

3 1/8 - 1 7/8

25/8 - 15/8

10/8

1 2/8

You can simplify this further to get 1 1/4. Hope this helps!

Answer: First lets make 3 1/8 to a improper fraction

multiply 3 * 8 to 24

add 24 + 1 to 25

lets make 1 7/8 an improper fraction

multiply 1 * 8 to 8

add 8 + 7 to 15

join the denominators together

10/8

simplify 10/8 to 5/4

Now lastly make 5/4 a mixed fraction

Answer: 1 1/4.

multiply 3 * 8 to 24

add 24 + 1 to 25

lets make 1 7/8 an improper fraction

multiply 1 * 8 to 8

add 8 + 7 to 15

join the denominators together

10/8

simplify 10/8 to 5/4

Now lastly make 5/4 a mixed fraction

Answer: 1 1/4.

Six less than the product of 3 and a number is 4. use the variable b for the unknown number

Six less than means -6 the product of 3 and a number (3 times b) is four=4

-6+3 times b=4

pemdas

multiplication first

3 times b=3b

3b-6=4

add 6 to both sides

3x=10

divide both sides by 3

x=10/3

-6+3 times b=4

pemdas

multiplication first

3 times b=3b

3b-6=4

add 6 to both sides

3x=10

divide both sides by 3

x=10/3

Answer:

- 1.625 and 2

Step-by-step explanation:

If you take 4 and multiply 1.625 you get 3.25 (Negative) then you multiply the 1.625 to 2 (positive) and it makes, -13.

The mean per capita consumption of milk per year is 140 liters with a standard deviation of 22 liters. If a sample of 233 people is randomly selected, what is the probability that the sample mean would be less than 137.01 liters? Round your answer to four decimal places.

Answer: 0.0192

Step-by-step explanation:

Given : The mean per capita consumption of milk per year :

Standard deviation :

Sample size :

Let be the sample mean.

The formula for z-score in a normal distribution :

For

The P-value =

Hence, the probability that the sample mean would be less than 137.01 liters is 0.0192 .

Consider the equation 6x+3y=9 Which equation, when graphed with the given equation, will form a system with infinitely many solutions? y+2x=3

y+2x=9

y=2x+3

y=-2x+9

Okay so when you need to find an equation that is infenetely many solutions, both equations needs to be equal like x=x so when x is 2, it is 2=2 whatever number you put, they are equal. That's why it is infenetely many solutions.

First, lets simplify the equation

3y=9-6x (the common number is 3 so lets divide them all to 3 so we will have one variable on one side all alone which is y)

y=3-2x

Let's look at the answers. We need to leave y on one side.

A. y=3-2x

B. y=9-2x

C. y=2x+3

D. y=-2x+9

When we simplify the equation on the top, we got y=3-2x so the answer is A

Hope it helped :)
