whats the circumference?

Answer:40c^2-46c -14

Step-by-step explanation:

(8c+2)*(5c-7)

8c*(5c-7)+2(5c-7)

40c^2-56c+10c-14

40c^2-46c-14

Answer:

Explanation:

(8c + 2)(5c-7) = 40c²-56c+10c-14

(8c + 2)(5c-7) = 40c²-46c-14

Answer:

210

Step-by-step explanation:

Step 1: 6 rows and 6 columns each side so 6*6=36

Step 2: we have 6 sides so 36*6=216 cubes

Step 3: substract 6 cubes from the total since each row and column shares the same cube 216-6=210 cubes

The total number of unit cubes is A = 210 cubes and volume is V = 216 units³

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Volume of Rectangle = Length x Width x Height

Volume of Rectangle = Area of Rectangle x Height

Given data ,

Let the height of the rectangle be = 6 units

Let the length of the rectangle be = 5 units

And , let the width be = 7 units

So , Volume of Rectangle = Length x Width x Height

V = 6 x 5 x 7

V = 210 units³

Hence , the number of unit cubes is A = 210

Answer:

The calculated value Z = 1.39 <1.96 at 0.05 level of significance

The null hypothesis is accepted

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 43

Given that the mean of the sample = 47

Given that the standard deviation of the Population = 25

Given that the sample size 'n' = 76

Step(ii):-

Null hypothesis:H₀: μ = 43

Alternative Hypothesis: H₁: μ ≠ 43

Test statistic

           [tex]Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]

          [tex]Z = \frac{47-43 }{\frac{25}{\sqrt{76} } }[/tex]

          Z = 1.39

Level of significance = 0.05

The critical value = 1.96

Final answer:-

The calculated value Z = 1.39 <1.96 at 0.05 level of significance

The null hypothesis is accepted

Answer:

1. A. 66 cubic inches.

2. A. 151,410,000

Step-by-step explanation:

For number one: Multiply 3 x 4 and that will give you 12 then multiply that by 11 and that will also give you 132. Lastly, divide 132 by 2 and it will get you 66 cubic inches.

For Number two: Multiply 420 by 721,000 and that will give you 302,820,000.

Once you have that, divide it by 2 and will give you 151,410,000.

Step-by-step explanation:

Given function is,

[tex]y=(\frac{1}{2})^x[/tex]

In the given exponential function,

Base of the function = [tex]\frac{1}{2}[/tex]

By the property of an exponential function,

1). If the base is between 0 and 1, function will be a growth function.

2). If the base is greater than 1, function will be a decay function.

Therefore, given function is a decay function.

Input-output table,

x             -2                -1               0                1                 2

y      [tex](\frac{1}{2})^{-2}=4[/tex]     [tex](\frac{1}{2})^{-1}=2[/tex]     [tex](\frac{1}{2})^{0}=1[/tex]   [tex](\frac{1}{2})^1=\frac{1}{2}[/tex]      [tex](\frac{1}{2})^2=\frac{1}{4}[/tex]

Step-by-step explanation:

median is the middle number, or in this case the sum of the middle number divided by 2

5 + 7 = 12/2

6

Answer:

18: mean = 70.5

median = 76.5

range = 76

20:

mean = 70.83

median = 76.5

range = 76

84:

mean = 81.5

median = 79.5

range = 20

78:

mean = 80.5

median = 81

range = 20

81:

mean = 81

median = 80.25

range = 20

82.5:

mean = 81.5

median = 80.25

range = 20

Step-by-step explanation:

mean = average = sum of numbers / amount of numbers present

median = middle number (arranged least to greatest)

range = largest number - smallest number

Answer:

960 cm²

Step-by-step explanation:

Volume = height x length x width

Volume = 1920 cm²

Since this prism is half

Volume = 1/2 ( 1920)

Volume = 960 cm²

Answer:

23 boxes of toys are being stored.

Step-by-step explanation:

There is a fixed cost of $1200 a month for rent and a variable cost of $5 per box of toys that are stored

This means that for x boxes of toys stored, the total cost is of:

[tex]C(x) = 1200 + 5x[/tex]

If the total cost for this month was $1315, how many boxes of toys are being stored?

This is [tex]x[/tex] for which [tex]C(x) = 1315[/tex]. So

[tex]C(x) = 1200 + 5x[/tex]

[tex]1315 = 1200 + 5x[/tex]

[tex]5x = 115[/tex]

[tex]x = \frac{115}{5}[/tex]

[tex]x = 23[/tex]
