Answer:

A

Step-by-step explanation:

Hey There!

So the first thing that we want to do is find the formula for volume of a pyramid

[tex]V=\frac{lwh}{3}[/tex]

l = length

w = width

h = height this is a square pyramid so if the length is 8 then the width is 8

So all we have to do now knowing the formula is plug in the values

[tex]V=\frac{8*8*9}{3} \\8*8=64\\V=\frac{64*9}{3} \\64*9=576\\V=\frac{576}{3} \\\frac{576}{3} =192\\[/tex]

So we can conclude that the volume of the square pyramid is 192

hope this helps :)

Answer:

198

Step-by-step explanation:

V= a^2 h/3 = 8^2 x 9/3 = 192

Or

Volume = The base edge squared multiplied by the height divided by three. Which would convert to-

Volume = 8^2 x 9/3 = 192

The situation can be modeled by a geometric sequence with an initial term of 284. The student population will be 104% of the prior year, so the common ratio is 1.04.

Let \displaystyle PP be the student population and \displaystyle nn be the number of years after 2013. Using the explicit formula for a geometric sequence we get

{P}_{n} =284\cdot {1.04}^{n}P

n

=284⋅1.04

n

We can find the number of years since 2013 by subtracting.

\displaystyle 2020 - 2013=72020−2013=7

We are looking for the population after 7 years. We can substitute 7 for \displaystyle nn to estimate the population in 2020.

\displaystyle {P}_{7}=284\cdot {1.04}^{7}\approx 374P

7

=284⋅1.04

7

≈374

The student population will be about 374 in 2020.

Answer:

Equation: 49 = 3x + 7

Answer: x = 14

Step-by-step explanation:

Let Kendra's daughter's age be denoted by the variable, x.

Set the equation. Note that:

Kendra is 49 years old.

Kendra is 3 times her daughter's age (x) plus 7 years.

Equation: 49 = 3x + 7

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, subtract 7 from both sides of the equation:

49 (-7) = 3x + 7 (-7)

49 - 7 = 3x

42 = 3x

Next, divide 3 from both sides of the equation:

(42)/3 = (3x)/3

x = 42/3

x = 14

14 is your answer.

Answer:

0.73 = 73% probability that an attendee sits in on the information technology session or the social media session.

Step-by-step explanation:

What is the probability that an attendee sits in on the information technology session or the social media session?

They cant be in both sections simultaneously, so this probability is the sum of each probability.

0.11 = 11% probability that an attendee sits in on the information technology session

0.62 = 62% probability that an attendee sits in on the social media session

0.11 + 0.62 = 0.73

0.73 = 73% probability that an attendee sits in on the information technology session or the social media session.

Answer: The eccentricity of the conic section shown in the given picture = 0

Step-by-step explanation:

The eccentricity of a conic is measure to determine how un-circle a conic section.

In the given picture, we have a circle.

A circle has an eccentricity of zero.

Therefore, the eccentricity of the conic section shown in the given picture = 0

Answer:

A -  (2a+0)/2 ; (2b+0)/2  = ( a , b )

B -  (-2a+0)/2 ; (2b+0)/2  = ( - a, b )

Using technology, the regression equation which predicts fall festival attendance with amount spent on 4th of July fireworks is ;

ŷ = 0.52X + 3.99

Coefficient of determination ; R² is 0.26

This means that about 26% of variation in the fall festival attendance is explained by the regression line.

The regression Coefficient, R = sqrt(R²) = sqrt(0.2625) = 0.5123

This depicts that a faiy strong positive correlation exists between the amount spent on 4th July fireworks and the fall festival attendance.

Answer:

Volume = 27 cubic units

Step-by-step explanation:

First, the formula of volume is l x h x w.

Second, the l, h, and w, are all 3, so to get your answer you do 3 x 3 x 3 which equals 27.

Answer:

[tex] 9 \frac{1}{3} [/tex]

Step-by-step explanation:

Let when x divided by 7 will produce [tex] 1\frac{1}{3} [/tex]

[tex]x \div 7 = 1 \frac{1}{3} \\ \\ x \times \frac{1}{7} = \frac{4}{3} \\ \\ x = \frac{7 \times 4}{3} \\ \\ x = \frac{28}{3} \\ \\ x = 9 \frac{1}{3} [/tex]

If your struggling with this is how you do it a quotient is the answer to a division problem. The divisor is the number of parts you divide the dividend by. The dividend is the number you are dividing.

Example: 12 ÷ 3 = 4, 4 is the quotient

Step-by-step explanation:

( 3 + √ 7 ) ( 3 − √ 7 ) = 2 Explanation: You can simplify this expression by using the formula for the difference of squares a 2 − b 2 = ( a − b ) ( a + b ) In your case, you ca say that a = 3 and b = √ 7 . This means that you have ( 3 + √ 7 ) ( 3 − √ 7 ) = 3 2 − ( √ 7 ) 2 = 9 − 7 = 2 Alternatively, if you don't know the formula for the difference of squares, you can rewrite this expression by expanding the parantheses ( 3 + √ 7 ) ( 3 − √ 7 ) = 3 ⋅ 3 − 3 ⋅ √ 7 + 3 ⋅ √ 7 − √ 7 ⋅ √ 7 Once again, the result will be 3 ⋅ 3 − √ 7 ⋅ √ 7 = 3 2 − 7 = 2
