Candlelight Books kept a record of how its sales increased based on

zavuch27 [327]

Answer:

Step-by-step explanation:

We need to understand the meaning of slope. The slope means the rate of change of y with every unit change of x.

In our case, it will be rate of change of sales increase (%) with respect to unit change of discount(%).

The formula for slope is the change in y divided by change in x.

From the 2 points given, we can say that slope is:

$\frac{62-32}{20-10}=\frac{30}{10}=\frac{3}{1}$

This means "as discount increases 1%, sales increase by 3%". Option D is right.

scoray [572]

Answer:

The corresponding point is (1,-4)

Step-by-step explanation:

we know that

The point (1,-8) is on the graph of f(x)

that means

For $x=1, f(1)=-8$

therefore

For the function 1/2f(x)

For $x=1, 1/2f(1)=-8/2=-4$

The corresponding point is (1,-4)

Fifteen seventh graders were randomly selected to see how many pushups in a row they could do. Their data are shown. a. b. 45, 4

GuDViN [60]

Answer: Median = 42

Mean = 43.8

Step-by-step explanation:

When we have a data set of n points {x₁, x₂, ..., xₙ}

The mean is written as:

(x₁ + ... + xₙ)/N

And the median will be the value in the middle of the data set.

So first, let's write our data set in order, from least to greatest.

{36, 36, 38, 40, 40, 40, 42, 42, 43, 45, 45, 48, 48, 70}

So we have 14 values.

The middle value will be at:

(n + 1)/2

(14 + 1)/2 = 7.5

Now, counting from the left, we have that the 7.5th value is 42. (the 7th value is 42, and the 8th value is 42)

So the median is 42.

Now the mean:

M = (36 + 36 +38 +40+40+40+ 42 +42 + 43 + 45 + 45 + 48 + 48 + 70)/14

M = 43.8

29+(×-24)=64 find x

irga5000 [103]

Answer:

x = 59

Step-by-step explanation:

So first lets distribute;

29 + x - 24 = 64

Collect like terms;

5 + x = 64

Subtract 5 from both sides;

x = 59
