Answer:

84 square inches

Step-by-step explanation:

The mean, median, and mode of the given data are 89, 92 and 82 respectively.

The measures of dispersion that we have are the mean, median and the mode.

The mean is the average of the given data

Mean = Sum/sample size

Mean = 96+81+82+99+94+92+95+82+80/9

Mean = 801/9

Mean = 89

Median is the middle value after rearrangement

80, 81, 82, 82), 92, (94, 95, 96, 99

Hence the medianof the data is 92

Mode is the number occuring the most. Since 82 occurs the most, hence the mode is 82

The mean, median, and mode of the given data are 89, 92 and 82 respectively.

He must consume only 4.9 gigabytes to maintain his bill at $73.50 per month.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
According to the question,
Oliver pays a flat cost of $49 per month and $5 per gigabyte.
Let the number of gigabytes he consumes be x,
He wants to keep his bill at $73.50 per month. So,
49 + 5x = 73.50
5x = 73.50 - 49
x = 24.5/5
x = 4.9

He must not consume less or more than 4.9 gigabytes to maintain his bill at $73.50 per month.

Thus, he must consume only 4.9 gigabytes to maintain his bill at $73.50 per month.

Answer:

[tex]a_{n}[/tex] = 3n + 4

Step-by-step explanation:

there is a common difference between consecutive terms , that is

10 - 7 = 13 - 10 = 16 - 13 = 3

this indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 7 and d = 3 , then

[tex]a_{n}[/tex] = 7 + 3(n - 1) = 7 + 3n - 3 = 3n + 4

Answer:

The nth term = 3n + 4.

Step-by-step explanation:

The formula for the nth term of an arithmetic progression is a(n) = dn + a(1) - d.

So this breaks down simply to,

a(n) = dn + a(1) - d a(n) = 3n + 7 - 3 a(n) = 3n + 4

Answer:

y = 0.5x + 5

Step-by-step explanation:

Use the slope formula to find the slope of a line given the coordinates of two points on the line.

The slope formula is:

m = [tex]\frac{y{2}-y{1} }{x{2}- x{1} }[/tex] = [tex]\frac{y}{x}[/tex]

The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

Now let's fill in the formula with the points,

m = [tex]\frac{8-4}{9-7}[/tex]

Solve,

⇒ Y = 9 – 7 = 2

⇒ X = 8 – 4 = 4

m = [tex]\frac{8-4}{9-7}[/tex] = [tex]\frac{2}{4}[/tex]

Simplify,

⇒ [tex]\frac{2}{4}=\frac{1}{2}=0.5[/tex]

Therefore, the Equation of the line is y = 0.5x + 5.

Answer:

f(-1) = 4

Step-by-step explanation:

Using the Quadratic Formula [tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}, \frac{-b-\sqrt{b^2-4ac} }{2a}[/tex] our Polynomial to find our zeros values on the x-axis.

Any other factoring method that you can think and do can also work.

To find our (h,k) or origin we use this formula [tex]h=x=-\frac{b}{2a}[/tex] and then plug our h=x into the equation to get out k.

To find our y-intercept. Plugin x = 0 into the equation to get y.

I used the internet to factory your equation f(x) and got
f(x) = 2(4x+3)(x-1)

x = -3/4 , 1

Substitute -1 into the equation to solve f(-1).

f(-1) = 8*(-1)^2 - 2*(-1) - 6 = 8 + 2 - 6 = 4

f(-1) = 4

[tex]P=250000e^{0.013t}\implies \stackrel{P}{450000}=250000e^{0.013t}\implies \cfrac{450000}{250000}=e^{0.013t} \\\\\\ \cfrac{9}{5}=e^{0.013t}\implies \log_e\left( \cfrac{9}{5} \right)=\log_e(e^{0.013t})\implies \ln\left( \cfrac{9}{5} \right)=0.013t \\\\\\ \cfrac{\ln\left( \frac{9}{5} \right)}{0.013}=t\implies 45.21\approx t\qquad \textit{about 45 years, 2 months and a half}[/tex]
