Answer:

A) −3

Step-by-step explanation:

recall that the general form for a linear equation is y = mx + b,

where m = slope and b = y-intercept

if we compare our given equation to the general equation:

y = −3 x + 3 vs. y = mx + b

we can clearly see that

slope, m = -3

y intercept, b = 3

Geet sells televisions. He earns a fixed amount for each television and an additional $ 30 if the buyer gets an extended warrant

pashok25 [27]

Answer:

The fixed amount Geet earns for each television is <u>$60</u>.

Step-by-step explanation:

Given:

Geet sells televisions. He earns a fixed amount for each television and an additional $ 30 if the buyer gets an extended warranty.

If Geet sells 17 televisions with extended warranties, he earns $ 1,530.

Now, to find the fixed amount Geet earns for each television.

Let the cost of fixed amount be $x$ .

Number of television = 17.

He earns total = $1,530.

He earns additional amount = $30.

Now, to get the fixed amount we put an equation:

$17(x+30)=1530$

$17x+510=1530$

<em>Subtracting both sides by 510 we get:</em>

$17x=1020$

<em>Dividing both sides by 17 we get:</em>

$x=60.$

Therefore, the fixed amount Geet earns for each television is $60.

A pool measuring 16 meters by 22 meters is surrounded by a path of uniform width, as shown in the figure. If the area of the po

lesantik [10]

Let X be the width of the path.

The width of the path would be the width of the pool plus 2x, so 2x +16

The length of the path would be the length of the pool plus 2x, so 2x+22

The total area is 832 square feet.

Area is found by multiplying the length by the width.

So you have:

(2x+16) (2x+22) = 832

Use the Foil Method:

(2x+16) (2x+22) = 4x^2 +76x+352

Now you have:

4x^2 +76x+352 = 832

Subtract 832 from both sides:

4x^2 +76x+352-832 = 0

Simplify:

4x^2 +76x -480

Factor the left side:

4(x-5)(x+24) = 0

Divide both sides by 4:

(x-5)(x+24) = 0

Set both parenthesis to equal 0 and solve for x:

x=5 and x = -24

The width of the path cannot be a negative number, so the width is 5 meters.

A simple random sample of 85 is drawn from a normally distributed population, and the mean is found to be 146, with a standard d

MatroZZZ [7]

The correct option is ''The value of 135 because it is not greater than 136.5 values is outside the 99% confidence interval for the population mean''

<h2>Given that,</h2>

A simple random sample of 85 is drawn from a normally distributed population, and the mean is found to be 146, with a standard deviation of 34.

Which of the following values is outside the 99% confidence interval for the population mean?

<h3>According to the question,</h3>

A simple random sample of 85 is drawn from a normally distributed population, and the mean is found to be 146, with a standard deviation of 34.

Sample space n = 85,

Mean = 146

And standard deviation = 34

Then, The standard error of the sample is,

$= \dfrac{\sigma}{n}\\\\= \dfrac{34}{\sqrt{85}}\\\\= \dfrac{34}{9.21}\\\\= 3.6$

Then, z-critical value for 99% is 2.58,

Margin of error = ±9.515

Confidence interval for lower bound is,

= 146 - 9.515 = 136.485

And confidence interval upper bound is,

= 146 + 9.515 = 155.515

Here, 135 is less than the lower bound,

Therefore, 135 does not lie within a 99% confidence interval.
