Why

The value of the function at x = 2 will be 5.

A function is a statement, tenet, or rule that establishes a connection between two variables. Mathematics is replete with functions, which are necessary for the construction of intricate relationships.

The result of the calculation that the mathematical model depicts is the expression's result when the necessary parameters and natural laws are given values.

The table represents a function.

x     f(x)

-1     5

0     10

2     8

9     14

In the above table, we can see that at the value of x = 2 in the function the value of the whole function is 5.

Answer:

8 tablets

Step-by-step explanation:

t = # tablets she must sell

348 = 33t + 84

264 = 33t

t = 8

The sales associate needs to sell at least 8 tablets in order to make at least $348 in one day.

To determine the minimum number of tablets the sales associate needs to sell in order to make at least $348 in one day, we can set up an inequality based on the given information.

Let's denote the number of tablets sold as "x."

Given:

Earnings per day (base pay) = $84

Commission per tablet sold = $33

Desired earnings for the day = $348

The total earnings for the day can be calculated as follows:

Total earnings = Base pay + (Commission per tablet * Number of tablets sold)

Total earnings ≥ Desired earnings

Setting up the inequality:

$84 + ($33 * x) ≥ $348

Simplifying the inequality:

$84 + $33x ≥ $348

Now, let's solve for x:

$33x ≥ $348 - $84

$33x ≥ $264

Dividing both sides of the inequality by $33 (the coefficient of x):

x ≥ $264 / $33

x ≥ 8

Therefore, the sales associate needs to sell at least 8 tablets in order to make at least $348 in one day.

Answer:

4.1 in

Step-by-step explanation:

[tex]V=\pi r^{2}[/tex]

[tex]751=\pi r^{2}(10.7)[/tex] now we multiply pi and 10.71- i left it in the hundreths

place when i get my final answer ill round it to the tenths)

[tex]751=33.62r^{2}[/tex],  we need the [tex]r^{2}[/tex] alone so we now dive with 33. 62 on both sides, elimenating the 33.62. Now 751/ 33.62= 16.98.

now we square root it

[tex]\sqrt{16.98}[/tex] = 4.12 which rounded is 4.1

Answer:

solution given.:

radius=[r] let

height[h]=10.7in

volume[V] of cylinder=751 in³

π=3.14

we have

volume[V] of cylinder=πr²h

751=πr² ×10.7

r²=[tex] \frac{751}{10.7×3.14} [/tex]

r=[tex] \sqrt{22.353} [/tex]=4.73inch

so radius is 4.73in

Answer:

95% of the confidence interval for the proportion of smokers who have tried to quit within the past year    

(0.47228 , 0.49868)

Step-by-step explanation:

Step(i):-

Given that the National Center for Health Statistics interviewed 5409 adult smokers in 2015

and 2626 of them said they had tried to quit smoking during the past year

proportion

                            [tex]P = \frac{x}{n} = \frac{2626}{5409} =0.48548[/tex]

                          Q = 1-P = 1 - 0.48548 = 0.5146

Step(ii):-

95% of the confidence interval for the proportion of smokers who have tried to quit within the past year      

[tex](P - Z_{\alpha } \sqrt{\frac{PQ}{n} } , P+ Z_{\alpha } \sqrt{\frac{PQ}{n} } )[/tex]      

[tex](0.48548 - 1.96 \sqrt{\frac{0.48548 X 0.51452}{5409} } , 0.48548+ 1.96\sqrt{\frac{0.48548 X 0.51452}{5409} } )[/tex]

( 0.48548 - 0.0132 , 0.48548 +0.0132)

(0.47228 , 0.49868)

Final answer:-

95% of the confidence interval for the proportion of smokers who have tried to quit within the past year    

(0.47228 , 0.49868)

Answer:

1028.5 is the mean

Answer:

481.75

Step-by-step explanation:

To find the mean add up all the numbers in the data set :

8 + 445 + 276 + 1198 = 1927

divide the numbers by how many numbers are in the data set :

1927 ÷ 4 = 481.75

Therefore, the mean in the data set 481.75

Answer:

[tex]y=12.5 sin(180\pi x-\frac{\pi}{2})+13[/tex]

Step-by-step explanation:

In order to solve this we can start by drawing a sketch of the problem (see attached picture)

So fist, let's take the general form of a sinusoidal movement:

[tex]y=Asin(\omega x+\phi)+b[/tex]

where:

A= amplitude

[tex]\omega[/tex]= angular frequency

x= time

[tex]\phi[/tex] = horizontal shift

b= vertical shift.

In this case, the amplitude will be the maximum distance between the center of the wheel and the highest or lowest point of the trajectory, in this case:

A= 13in - 0.5in =12.5 in

The angular frequency is how many radians the wheel will turn in a minute, so we get:

[tex]\omega=\frac{90 rev}{min}*\frac{2\pi rad}{1 rev}[/tex]

[tex]\omega=180\pi rad/min[/tex]

Generally, the sin function will start at the center of the circular movement. In this case, since it starts on the lowest point, we can say that the graph moves right by [tex]\frac{\pi}{2} rad[/tex], so in this case:

[tex]\phi=-\frac{\pi}{2}[/tex]

and finally, the vertical shift is the distance between the center of the circular movement and the ground so in this case:

b=13in

so when putting it all together we get our equation to be:

 [tex]y=12.5 sin(180\pi x-\frac{\pi}{2})+13[/tex]
