Which answer best describes the shape of this distribution?


skewed left

uniform

bell-shaped

skewed right

Answer:

[tex]( {x}^{2} + 16x + 64) - (x + 8)(x - 4) = k(x + 8) \\ ( {x + 8)}^{2} - (x + 8)(x - 4) = k(x + 8) \\ (x + 8) - (x - 4) = k \\ k = (x - x) + (8 + 4) \\ k = 12[/tex]

Answer:

Step-by-step explanation:

a² + 2ab + b² = (a + b)²

2ab = 2 * x * 8 = 16x

x²  + 16x + 64 = x² + 2* x * 8 + 8²  

                      = (x + 8)²

x² + 16x + 8 - (x +8)(x - 4) = (x+8)² - (x+ 8) (x -4)

                                        = (x +8)(x +8) - (x + 8)(x - 4)

(x +8 ) is common in both terms

                                        = (x + 8) [ (x + 8) - (x - 4) ]

                                        = (x + 8) [ x + 8 - x + 4 ]  

{Combine like terms. so x + (-x ) = 0   and 8 +4 = 12}

                                         = (x + 8) [ 12]

k = 12

Answer:

1. Mean: 103

2. Median: 8

3. Mean would increase.

Step-by-step explanation:

1. 82+85+89+94+98+103+105+108+112+115+119+126 = 1,236

Then, 1,236/ 12 = 103

Therefore, our answer!

2. Put the numbers in order from least to greatest:

1, 6, 7, 8, 9, 11, 16

Cross out one on each side until you get to the middle.

3. Add up all original numbers to get a mean of: 2.7 and then add up all the numbers including six to get a mean of: 3.2 As you can see, the mean increased.

Hope this helps, good luck! :)

The Mean is 103 ,Median is 8 and Mean would increase

What is mean and median?

The mean (informally, the “average“) is found by adding all of the numbers together and dividing by the number of items in the set.

The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number.

according to the question,

1. 82+85+89+94+98+103+105+108+112+115+119+126 = 1236

Then, 1236/ 12 = 103

Therefore, our answer

2. Put the numbers in order from least to greatest:

1, 6, 7, 8, 9, 11, 16

Answer:

The numbers are 44 and 36

Step-by-step explanation:

n + n - 8 = 80

2n - 8 = 80

2n (- 8 + 8) = 80 + 8

2n = 88

2n/2 = 88/2

n = 44

44 - 8 = 36

What is the total number of students who brought water bottles to lunch?

Answer: Choice B

(3+4) + 2 = 3 + (4+2)

=========================================

Explanation:

The general rule for the associative property of addition is

(a+b)+c = a+(b+c)

the a,b,c stay in the same order from left to right. The only thing that changes is the way we group the pair of terms. On the left side, we have a & b together with c left out. Then on the right side, we have b & c together with 'a' excluded.

Addition of any group of numbers can be done in any order, which is why this property is valid (though perhaps there's a more rigorous proof out there). For this specific problem, a = 3, b = 4, and c = 2.

Answer:

D) 120

Step-by-step explanation:

if there are 40 blue marbles and the ratio of blue is 8, then the multiplier is 5

# of red marbles:  11 x 5 = 55

# of pink marbles:  5 x 5 = 25

55 + 40 + 25 = 120

for question 1

Area of Base B =45×25 = 1125 cm²

perimeter of base P = 2(45+25) = 140 cm

Height = 15 cm

Using the formula

Surface area = 2B + Ph

A = 2×1125 + 140×15= 4350 cm²

Voume = Bh = 1125×15= 16875 cm³

For question 2,

Area of base = 7× 5/2= 17.5 cm²

Perimeter of base = (7+7+7) = 21 cm

Surface area = 2B + Ph

Surface area of prism = 2×17.5+ 21×10 = 245cm²

Volume = Bh = 17.5×10 = 175 cm³

The linear equation that represents the table is [tex]y = -0.53x + 62.33[/tex]

A linear function is a graph that has a constant rate.

From the table, we have the following ordered pairs

(x,y) = (0,62.33) and (1, 61.8)

Start by calculating the slope (m)

[tex]m = \frac{y_2 -y_1}{x_2-x_1}[/tex]

So, we have:

[tex]m = \frac{61.8 -62.33}{1-0}[/tex]

[tex]m = -0.53[/tex]

The linear equation is then calculated as:

[tex]y = m(x -x_1) + y_1[/tex]

So, we have:

[tex]y = -0.53(x -0) + 62.33[/tex]

Expand

[tex]y = -0.53x + 62.33[/tex]

Hence, the linear equation that represents the table is [tex]y = -0.53x + 62.33[/tex]
