1. The National Football League (NFL) has been finding new ways to reduce the risk of its players
getting concussions. For example, helmets have changed to keep players more safe. In the 2017-
2018 season, 190 athletes reported concussions out of 1700 total players. In the 2018-2018
season, 135 concussions were reported out of total 1650 players.
a. Make a two way table displaying this information.
TOTAL
b. Calculate the risk of a football player reporting a concussion in 2017-2018 and 2018-2019.
C. Find the absolute risk reduction.

Answer:

He scored better on the second test by a margin of 3%.

Step-by-step explanation:

Find the percentage of each one by dividing Ahmed's score / Total possible score

24/30 = 0.8 > move the decimal place over twice for % > 80%

20/24 = 0.83333 > move the decimal place over twice for % > 83%

He scored 3% better on the second test.

Answer:

He originally spent 120$

He made 12 extra dollars.

Step-by-step explanation:

To solve this I turned the 110% into a decimal.

So I divided 110 by 100 and got 1.1

In order to find the original number you would then need to divide the total cost of the bicycle and helmet together by 1.1

So, 116 + 16 = 132

132/1.1= 120

[tex] \frac{ {7x}^{2} - 5x + 1}{4x + 1} [/tex]

Step-by-step explanation:

Since the denominators are the same we just have to combine the top.

[tex] {x}^{2} - 5x + {6x}^{2} + 1[/tex]

Combine alike terms.

[tex] {7x}^{2} - 5x + 1[/tex]

put that over our denominator.

Answer:

[tex] y = \frac{3}{2}x [/tex]

Step-by-step explanation:

The graph shows there is a proportional relationship between amount of grams of fish (x) and number of calories (y).

A original relationship can be represented by An equation as [tex] y = kx [/tex], where, k = constant of proportionality (y/x).

The constant of proportionality using any point, let's say (200, 300), would be:

k = y/x = 300/200 = ³/2

Plug in the value of k into [tex] y = kx [/tex].

Thus, the equation that reflects the relationship would be:

[tex] y = \frac{3}{2}x [/tex]

The equation that reflects this relationship using x to represent the amount of fish in grams and y to represent the number of calories is (2y = 3x) and this can be determined by using the point-slope form of a line.

Given :

The point-slope form can be used to determine the equation that reflects this relationship using x to represent the amount of fish in grams and y to represent the number of calories.

The point-slope form is given by the equation:

[tex]\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]     ----- (1)

where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the points on the line.

Now, put the values of [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in the equation (1).

[tex]\dfrac{y-150}{x-100}=\dfrac{300-150}{200-100}[/tex]

[tex]2(y-150)=3(x-100)[/tex]

2y - 300 = 3x - 300

2y - 3x = 0

2y = 3x

The equation that reflects this relationship using x to represent the amount of fish in grams and y to represent the number of calories is (2y = 3x).

Answer:

L = 3x cm

Step-by-step explanation:

For this problem, let's consider the relation that is stated:

Length is 3 times as much as the width.  The width is x cm.

Mathematically we can say the following:

L = 3W

W = x cm

So we can say the following about the length:

L = 3W

L = 3(x cm)

L = 3x cm

Answer:

[tex]SE_p = 0.055[/tex]

Step-by-step explanation:

Given

[tex]n = 79[/tex] --- Heads

Proportion, p = 46 out of 79

Required

Determine the standard error for sample proportion (SEp)

This is calculated using the following formula

[tex]SE_p = \sqrt{\frac{p(1-p)}{n}}[/tex]

In this case:

[tex]p = \frac{46}{79}[/tex]

[tex]p = 0.5823[/tex]

Substitute values for p and n in:

[tex]SE_p = \sqrt{\frac{p(1-p)}{n}}[/tex]

[tex]SE_p = \sqrt{\frac{0.5823 * (1-0.5823)}{79}}[/tex]

[tex]SE_p = \sqrt{\frac{0.5823 * 0.4177}{79}}[/tex]

[tex]SE_p = \sqrt{\frac{0.24322671}{79}}[/tex]

[tex]SE_p = \sqrt{0.00307881911}[/tex]

[tex]SE_p = 0.0554871076[/tex]

[tex]SE_p = 0.055[/tex] ---- Approximated
