Answer:

I know the answer

Step-by-step explanation:

Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

Can you guys help me??

Plug the values (1,7) and (3,9) into the functions and see which function is true for both values. In this case, f(x) = x+6 holds true for both values, making it the correct answer.

QUICK!!! HELP PLEASE!!!!

kvv77 [185]

Answer:

0 —> 15

1 —> 13.75

2 —> 12.5

3 —> 11.25

Step-by-step explanation:

Every time she drives for 1 hour, the car uses up 1.25 gallons of gas. If she fills it up and doesn't drive anywhere, the car will still be full with 15 gallons. If she drives for an hour, you would need to subtract 1.25 from 15 which would equal 13.75.

Then if she drives another hour, then you would subtract another 1.25 from 13.75.

Or a quicker way to do it would be if you multiply the number of hours driven by the gallons used per hour then subtract it from the filled up tank.... So for example if she drove 3 hours —> 3•1.25=3.75 then 15-3.75=11.25

RideAnS [48]

Answer:

upper control limit $UCL=7.1632$

Concept :

$UCL=\bar{\bar{x}}+A_2\bar{R}$ where $A_2=0.34$

$\bar{\bar{x}}=\frac{\bar{x}}{n}$

$S=\frac{\bar{R}}{d}\Rightarrow \bar{R}=S\times d$ where $S=0.5, d=2.97$

Given :

She took a sample of per day $(n)$ is $9$ bottles.

The standard deviation $S$ of all bottles is $0.5$ degree.

Average across all $1017$ bottles $\bar{x}$ are $60$ degree Fahrenheit.

To find :

The value of the upper control limit (UCL)

Explanation :

Here, firstly we find the value of $\bar{\bar{x}}$ .

$\because\bar{\bar{x}}=\frac{\bar{x}}{n}$

$\therefore \bar{\bar{x}}=\frac{60}{9}$

$\Rightarrow \bar{\bar{x}}=6.66$ and $\bar{R}=S\times d$

$\Rightarrow \bar{R}=0.5\times2.97=1.48$

$\Rightarrow \bar{R}=1.48$

Now, $UCL=\bar{\bar{x}}+A_2\bar{R}$

$\Rightarrow UCL=6.66+0.34\times1.48$

$\Rightarrow UCL=6.66+0.5032$

$\Rightarrow UCL=7.1632$ degrees.

On a certain hot summer day, 481 people used the public swimming pool. The daily prices are 1.25 for children and 2.25 for adult

spayn [35]

Answer:the number of children that swam in the public pool that day is 222

the number of adult that swam in the public pool that day is 259

Step-by-step explanation:

Let x represent the number of children that swam in the public pool that day.

Let y represent the number of adult that swam in the public pool that day.

On a certain hot summer day, 481 people used the public swimming pool. This means that

x + y = 481

The daily prices are 1.25 for children and 2.25 for adults. The receipts for admission totaled to 86.25. This means that

1.25x + 2.25y = 860.25 - - - - - - - -1

Substituting x = 481 - y into equation 1, it becomes

1.25(481 - y) + 2.25y = 860.25

601.25 - 1.25y + 2.25y = 860.25

- 1.25y + 2.25y = 860.25 - 601.25

y = 259

Substituting y = 259 into x = 481 - y, it becomes

x = 481 - 259

x = 222
