Answer:

Step-by-step explanation:

So the plots are the 15 baseball players actually did, and the line was what they predicted to have.

You can see for the y-axis shows the numbers for home runs, each column add 2, and x-axis for hits, each line add 10.

For the first one you need to find the number for home runs when hits=154, so you can see the plot at the right side of 150 hits and left side of 160 hits. And the plot is located at y=26, which means 26 home runs.

The second one you have x=154, and y=0.15x-1.5,

so y=0.15x154-1.5=21.6

Answer:

3/2

Step-by-step explanation:

To multiply fraction×fraction, you multiply top×top and bottom×bottom.

2/3 × 3/2

= 6/6

= 1

The 3/2 is called the reciprocal. Take the number in the problem and flip it over to find the reciprocal.

In spite οf the fact that parabοlas might have οpenings that are upward οr dοwnward, varying "widths" οr "steepnesses," they all have the same basic "U" shape.

Quadratic parent: f(x)=x²

The graph is a parabοla with vertex V=(0,0) at the οrigin and οpens up.

When x=1→f(1)=1²→f(1)=1

1) g(x)

The graph οpens up, then there is nοt a reflectiοn acrοss the x-axis.

The vertex is at the pοint (-3,-3): 3 units tο the left and 3 units dοwn οf the vertex οf the parent funtiοn.

When x is 1 unit tο the right frοm the vertex g(x)=1

Then the transfοrmatiοns were applied tο the cuadratic parent functiοn are:

1.1) vertical shift dοwn 3.

1.2) hοrizοntal shift left 3.

2) h(x)

The graph οpens dοwn, then there is a reflectiοn acrοss the x-axis.

The vertex is at the οrigin (0,0).

When x is 1 unit tο the right frοm the vertex h(x)=-3

Then the transfοrmatiοns were applied tο the quadratic parent functiοn are:

2.1) reflectiοn acrοss the x-axis.

2.2) vertical strecht οf 3.

3) d(x)

The graph οpens up, then there is nοt a reflectiοn acrοss the x-axis.

The vertex is at the pοint (3,-3): 3 units tο the right and 3 units dοwn οf the vertex οf the parent funtiοn.

When x is 1 unit tο the right frοm the vertex d(x)=1

Then the transfοrmatiοns were applied tο the cuadratic parent functiοn are:

Answer:

Salma, joe, and alan sent 14, 69, and 23 text messages respectively

Step-by-step explanation:

Given that Salma, joe, and alan sent a total of 106 text messages during the weekend, it means that

s + j + a = 106 where s, j, and a are the number of messages sent by Salma, joe, and alan respectively

Given salma sent 9 fewer messages than alan

s = a - 9

Joe sent 3 times as many messages as alan

j = 3a

hence

a - 9 + 3a + a = 106

5a - 9 = 106

5a = 106 + 9

5a = 115

Divide both sides by 5

a = 115/5

= 23

s = 23 - 9

= 14

j = 3* 23

We know that the volume of the cylinder is 30 cubic units and that the cylinder and cone have the same height and base. Let's use the formula for the volume of a cylinder to solve for the radius.

V = pi*r^2*h
30 = pi*r^2*h

Since the height of the cylinder and cone are the same, we can use this value for h in the formula for the volume of a cone.

V = (1/3)*pi*r^2*h

Now we can substitute the value we found for h in terms of r into the formula for the volume of a cone.

V = (1/3)*pi*r^2*h
V = (1/3)*pi*r^2*(30/(pi*r^2))

Simplifying this expression, we get:

V = 10

Therefore, the volume of the cone is 10 cubic units.

First, we should find the slope of the line we're starting with.

3y = 6x + 5 can be put into slope-intercept form by dividing both sides by 3.

 y = 2x + 5/3

The slope of this line is 2.

A parallel line has to have a slope of 2 as well, so we know we're looking for a line with a slope of 2.

Options A and B have that.  Options C and D do not.

Now if (3,3) is a point on the line, then (3,3) must also be a solution for the equation.

Checking Option A:

    3 = 2(3) - 1  is not true.  3 ≠ 6 - 1

Checking Option B:

    3 = 2(3) - 3 is true.  3 = 6 - 3

Option B is the answer, since it has the right slope and works for the point (3,3).

Answer:

B) y = 2x - 3

Step-by-step explanation:

3y = 6x + 5  To put in the slope intercept form.  Divide all the way through by 3

y = 2x + 5/3

When lines are parallel, they have the same slope.

So the slope will be 2.  We will use the point to find the y intercept

m = 2

x = 3   This is from the point (3,3)

y = 3   this is from the point (3,3)

y = mx + b

3 = 2(3) + b

3 = 6 + b   Subtract 6 from both sides

3-6 = 6- 6 + b

-3 = b

Now that we have the slope (2) and the y intercept (-3) we can write the equation.

y = mx + b

y = 2x -3

An equation to model the relationship between the number of weeks, x, and the number of site visits, f(x) is 4800 = a(1.5)^x.

He found that before launching the new marketing plan, there were 4,800 visits.

Over the course of the next 5 weeks, the number of site visits increased by a factor of 1.5 each week.

Over the course of the next 5 weeks, initial visitor at x = 0, 4800

Increasing factor = 1.5

Equation of the model is given as:

f(x) = a(b)^x

From the question b = 1.5

Now the equation of model is:

f(x) = a(1.5)^x

At x = 0, f(x) = 4800

The population mean is 15.6 if A population consists of the following five values: 11, 13, 15, 17, and 22.

What is Mean ?

In statistics, the mean is a measure of central tendency of a set of numerical data. It is commonly referred to as the average, and is calculated by adding up all the values in the data set and dividing the sum by the total number of values.

a. To list all samples of size 3, we can take all possible combinations of 3 values from the population:

{11, 13, 15}: mean = 13

{11, 13, 17}: mean = 13.67

{11, 13, 22}: mean = 15.33

{11, 15, 17}: mean = 14.33

{11, 15, 22}: mean = 16

{11, 17, 22}: mean = 16.67

{13, 15, 17}: mean = 15

{13, 15, 22}: mean = 16.67

{13, 17, 22}: mean = 17.33

{15, 17, 22}: mean = 18

b. To compute the mean of the distribution of sample means, we need to find the mean of all the sample means computed in part (a). There are 10 sample means, so we add them up and divide by 10:

(13 + 13.67 + 15.33 + 14.33 + 16 + 16.67 + 15 + 16.67 + 17.33 + 18)  ÷10 = 15.4

To compute the population mean, we simply take the average of the population values:

(11 + 13 + 15 + 17 + 22) ÷ 5 = 15.6

Therefore, the population mean is 15.6
