I think the answer would be D.
Explanation:
I think it’s D because it asks which is “skewed right”, and most of the data is on the right side of D

What is the average rate of change of the function over the interval x = 0 to x = 8?

notsponge [240]

To find the average rate of change, use the following formula:

$\frac{f(b) - f(a)}{b-a}$

a and b represent the values of the interval:

$a = 0, b = 8$

Simplify the original equation by combining like terms:

$2x - 13x = -11x$
$f(x) = -11x + 5$

Plug the interval values into the f(x) equation:

$f(0) = -11(0) + 5 = 0 + 5 = 5$
$f(8) = -11(8) + 5 = -88 + 5 = -83$

Plug in these values into the average rate of change formula:

$\frac{-83 - 5}{8 - 0} = \frac{-88}{8} = -11$

The average rate of change over this interval is -11.

A house costs 36% more today than when it built.if the cost of the house today is $333200,find its cost when it was built

Brrunno [24]

Answer:

The cost of house was $245000 when it was built.

Step-by-step explanation:

Given that:

Cost of the house today = $333200

Percent increase in today's price = 36%

Let,

x be the cost of house when it was built.

100 be the percentage when the house was built.

Percentage of house price today = (100+36)% = 136%

136% of x = 333200

$\frac{136}{100}*x=333200\\1.36x=333200$

Dividing both sides by 1.36

$\frac{1.36x}{1.36}=\frac{333200}{1.36}\\x=245000$

Hence,

The cost of house was $245000 when it was built.

I NEED HELP

BaLLatris [955]

Answer:

$\dfrac{1}{6}\ \text{cups per hour}$

Step-by-step explanation:

V = volume

r = rate

t = time

Use formula $V=r\cdot t$ connecting volume, rate and time.

In your case,

$V=\dfrac{1}{4}$ cup of water

$t=1\dfrac{1}{2}$ hours

r is unknown.

Substitute all data into the formula:

$\dfrac{1}{4}=r\cdot 1\dfrac{1}{2}\\ \\\dfrac{1}{4}=r\cdot \dfrac{3}{2}\\ \\2\cdot \dfrac{1}{4}=3r\ [\text{Multipled by 2}]\\ \\3r=\dfrac{1}{2}\\ \\r=\dfrac{\frac{1}{2}}{3}\ [\text{Divided by 3}]\\ \\r=\dfrac{1}{6}\ \text{cups per hour}$

Find the value of x<br> DUE SUNDAY I NEED ASAP

Leto [7]

Answer:

x=43°

Step-by-step explanation:

The angles are adjacent and create a straight line so their sum is 180°.

(x+6)°+(3x+2)°=180°

x°+6°+3x°+2°=180°

4x°+8°=180°

4x°=172°

x=43°
