This is a hexagonal prism: Volume = Area of Base (hexagon) x Height:
There are 6 equal equilateral triangles in a hexagone.
The apothem (or altitude of each triangle) = side x (√3)/2 =12(√3)/2 = 6√3
Area of ONE equilateral triangle = (side x altitude)/2:
Area of ONE equilateral triangle = (12 x 6√3)/2 = 36√3 ft²
Area of the SIX equilateral triangles = 36√3 x 6 = 216√3 ft²
VOLUME = BASE X HEIGHT = 216√3 x 15 = 3240√3 ft³

OR VOLUME = 5612 ft³

The average number of passes in a football game is right skewed with mean 75 and variance 961. If we sample 100 random games, wh
suter [353]

Answer:

0.0066

Step-by-step explanation:

Given that:

Mean \mu = 75

Variance \sigma^2 =961

The standard deviation \sigma =  \sqrt{961} = 31

The sample size n = 100

\mu = \mu_{\overline x} = 75

\sigma _{\overline x} = \dfrac{\sigma }{\sqrt{n}}

\sigma _{\overline x} = \dfrac{31 }{\sqrt{100}}

\sigma _{\overline x} = \dfrac{31 }{10}}

\sigma _{\overline x} = 3.1

P(\overline x > 83.7) = 1 - P( \overline x < 83.7)

P(\overline x > 83.7) = 1 -P\bigg (  \dfrac{\overline x - \mu_{\overline x} }{\sigma _{\overline x}} < \dfrac{83.7 - 76}{3.1} \bigg)

P(\overline x > 83.7) = 1 -P\bigg (  Z< \dfrac{7.7}{3.1} \bigg)

P(\overline x > 83.7) = 1 -P (  Z< 2.48)

Using the Z table;

P(x > 83.7) = 1 - 0.9934

P(x > 83.7) = 0.0066

Thus, probability = 0.0066

Two consecutive integers are such that 7 times the biggest and then added to the smallest equals
Arturiano [62]

Answer:

61,62

Step-by-step explanation:

Let the smallest  number be x

Hence, the biggest number = x+1 [as it consecutive]

Hence,

7(x+1)+x=495

7x+7+x+495

8x=495-7

8x=488

x=61

Hence, smaller number=61, bigger number=62

Through:(-1, -2), slope = 5
kherson [118]

Answer:

y=5x+3

Step-by-step explanation:

Hi there!

We're given the point (-1, -2) and a slope of 5. We need to find the equation of the line in slope intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

Since we're already given the slope, we can substitute that immediately into the equation

here it is so far:

y=5x+b

now we need to solve for b

Since the line will pass through the point (-1,-2), we can use it to solve for b

substitute -1 as x and -2 as y into the equation

-2=5(-1)+b

multiply

-2=-5+b

add 5 to both sides

3=b

substitute that into the equation

therefore, the equation of the line is <u>y=5x+3</u>

Hope this helps! :)

Question~
Rasek [7]

Answer:

  • B. 1

Step-by-step explanation:

Multiply the first term by x^a, the second term by x^b, the third term by x^c.

<u>The first term becomes:</u>

  • x^a/(x^a+x^b+x^c)

<u>The second term becomes:</u>

  • x^b/(x^a+x^b+x^c)

<u>The third term becomes:</u>

  • x^c/(x^a+x^b+x^c)

<u>Their sum is:</u>

  • (x^a+x^b+x^c)/(x^a+x^b+x^c) = 1

Correct choice is B
