Answer:

34 people. (extremely sorry if this is wrong! please tell me if it is.)

Step-by-step explanation:

197 people were in the survey. First we can subtract 57 from 197 because 57 people dont like cats or dogs.

197-57 = 140

and to find the number of people that chose cats but not dogs, we subtract 106 from 140 which leaves us with 34 people.

B. [tex] {f}^{ - 1} (x) = 5x - 20[/tex]

Step-by-step explanation:

[tex]f(x) = \frac{1}{5} x + 4[/tex]

[tex]y = \frac{1}{5} x + 4[/tex]

[tex]x = \frac{1}{5} y + 4[/tex]

Hi! I'm happy to help!

When Jenna bought the milk, it deducted (subtracted) $3.58 from her $20. So, let's subtract that here:

20.00

- 3.58

We have to borrow:

19.9(10)

- 3.58

10-8=2

19.9(10)

- 3.58

    .  2

9-5=4

19.9(10)

- 3.58

    .42

9-3=6

19.9(10)

- 3.58

    6.42

and 1-0=1

19.9(10)

- 3.58

$16.42

So, Jenna would receive $16.42 in change for her $20 bill.

I hope this was helpful, keep learning!

Answer:-6 and -1

Step-by-step explanation:

Answer:

105 ft.

Step-by-step explanation:

5 x 12 = 60

So 5 feet is 60 inches.

60 + 3 = 63

That makes the ridge 63 inches long.

When the lion went up the ridge, it traveled 63 inches.

When the lion went back down the ridge, it traveled another 63 inches, totaling 126 inches.

The lion did this 10 times.

126 x 10 = 1260

Divide 1260 by 12 to find the measurement in feet.

1260 ÷ 12 = 105

Step-by-step explanation:

The formula for compounded interest is given by

[tex]A = P\left(1 + \dfrac{r}{n}\right)^{nt}[/tex]

where

A = amount of money after a time t

P = principal or initial amount of money

r = interest rate in decimal form

n = number of times money bnb is compounded per unit time

t = unit time

a) For this problem, P = $6000, n = 1 since the money is compounded once a year, t = 1 year and r = 0.18 so after one year, Lisa's money amounts to

[tex]A = (\$6000)\left(1 + \dfrac{0.18}{1}\right)= \$7,080[/tex]

b) After two years, the money is still compounded yearly so n = 1 but t = 2 years so Lisa's money amounts to

[tex]A = (\$6000)\left(1 + \dfrac{0.18}{1}\right)^{2} = \$8354.40[/tex]

Step-by-step explanation:

a)

Principal = $6000

Rate = 18%

Time = 1 year

A = P(1 + r/100)¹

A = 6000(1 + 18/100)

A = 6000(100 + 18/100)

A = 6000 × 118/100

A = 60 × 118

A = 7080

b)

Principal = $6000

Rate = 18%

Time = 2 years

A = P(1 + r/100)²

A = 6000(1 + 18/100)²

A = 6000(100 + 18/100)²

A = 6000(118/100)²

A = 6000 × 118/100 × 118/100

A = 6 × 118 × 118/10

A = 8354.4

True, two samples are selected from a population, and a treatment is administered to the samples. If both samples have the same mean and the same variance, you are more likely to find a significant treatment effect with a sample of n = 100 than with a sample of n = 4.

The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.

Given:

Two samples are selected from a population, and a treatment is administered to the samples.

If both samples have the same mean and the same variance.

That means, they have the same t statistic.

A t-test compares the average values of two data sets and determines if they came from the same population.

You are more likely to find a significant treatment effect with a sample of n = 100 than with a sample of n = 4.

Because the value of t-test are same.

Therefore, the statement is true.

Answer:

$5

Step-by-step explanation:

First, we need to find the total amount he spent on the passes.

We just need to multiply the number of passes by the price of each pass.

19 x 1.4 = 26.6

This means he spent $26.6 on the passes.

Now, we can find out how much he spent on the discount card.

Just subtract his total spending amount by the amount he spent on passes.

31.6 - 26.6 = 5

He spent $5 on the discount card.

Answer:

-1 = -5

0 = -1

2 =  5

Step-by-step explanation:

In order to do this you need to follow these five (5) steps:

1) Know what each of the variables mean in an equation of a line. The equation of a line is y = mx + b where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. (Remember that the slope is the steepness  of a line and the y-intercept is the point where the line intersects  the y-axis. The x- and y-coordinates are values of the points on the line of y = 3x - 1.)

2) Identify the m (slope) and the b (y-intercept). The slope is 3, which can also be written as 3/1. The y-intercept is -1. (Remember that subtraction of 1 is the SAME thing as adding -1!) Since the y-intercept is a point it will be plotted at (0, -1).

3) Plot the y-intercept first. Start at the origin (intersection of the x- and y-axes) since the x coordinate is 0. Then move DOWN 1 unit since the y-coordinate is negative.

4) Use the m (slope) to plot at least three new points. The slope can also be represented as "rise/run" or the amount of units that you move UP or DOWN (vertically), then LEFT or RIGHT (horizontally). (Remember: if the numerator is positive (move UP); numerator is negative (move DOWN); denominator is POSITIVE (move RIGHT); denominator is NEGATIVE (move LEFT)). Since our slope is 3/1, and both the numerator and denominator are POSITIVE, that means we will be "rising" (moving UP) 3 units and "running" (moving RIGHT) 1 unit.

Start at the y-intercept  of (0, -1) and move up 3 units and to the right 1 unit. You should be at (1, 2). Plot a point here. Then do it again. You should now be at (2, 5). Plot another point. Now, do it one more time. You should now be at (3, 8). Plot your last point. (If you wish to continue plotting additional points, feel free to do so.)
