There will be an estimated amount of 1125 faulty souvenir tokens.

Step-by-step explanation:

Hi!

So, let's do this problem out.

So we for every 400 tokens, 3 are faulty

Let's write that in a ratio

3:400

Ok, great!

So, now we know that:

3:400 = x:150,000

We can set up a percent proportion

[tex]\frac{3}{400} =\frac{x}{150,000}[/tex]

To find x, we do:

[tex]x=\frac{3*150,000}{400}[/tex]

[tex]x=\frac{450,000}{400}[/tex]

[tex]x=\frac{4,500}{4}[/tex]

[tex]x=1125[/tex]

There will be an estimated amount of 1125 faulty souvenir tokens.

Solve for x: 3(x-4)=12

Answers

the answer would be x=8
first, do distributive property. 3 • x and 3 • -4. Now you get 3x-12=12. Now add 12 to both sides. Now you have 3x=24. Now divide by 3 to get your x alone and you answer which is 8!

Round 6 6/13 to the nearest whole number.

Answers

6.

1/3 is not 1/2 or more than 1/2 so you have to round down.

Rounding to the nearest whole number involves writhing out the value of a number to the nearest integer value. Hence, the number would be written as 6

Converting the fractional value to decimal ; 6 61/3 = 6.461

Since the first digit after the decimal point is less than 5, we round to 0

Therefore, the number would be written as 6 (nearest whole number).

you should get 1625.

Find the amount of money spent on the food and find the difference of the two.

C. $390.00

Explanation:

Housing: 6,500/.25= $1,625
Food: 6,500/.19= $1,235

Subtraction:
$1,625 - $1,235= $390

What is Arithmetic Mean?

The simplest and most popular way to measure a mean or average is the arithmetic mean. It simply entails adding up a collection of numbers, then dividing that total by the total number of numbers in the series.

Given:

According to box plot the mean is

= (3 x 2+ 4 x 1 + 5 x 2 + 7 x 8 + 8 x 3+ 9x 5 + 10 x 5 ) / 26

= (6 + 4 + 10 + 56 + 24 + 45 + 50 ) / 26

= 195 / 26

= 7.5

Hence, the mean is 7.5.

Also, the median = (7+8)/2 = 7.5

Christopher put 12 gallons of gas in her car. She uses one gallon for every 20 miles he drives.

a. Write an equation to represent the total amount of gas left in his car based upon how many miles she has driven.
b. Find the slope and y-intercept.

Answers

Answer:

Equation: y=(-1/20)x+12.

Slope: -1/20

Y-intercept: (0, 12)

Step-by-step explanation:

Let x=the number of gallons of gas in Christopher's car.

If we start with 12 gallons, we have the equation: y=(-1/20)x+12.

This equation is already in slope intercept form, so we see that the slope is -1/20, and the y-intercept is (0, 12).
