24 is 2.5 standard deviations away from the mean.

Now it given that,

mean = 18

standard deviation = 4

value = 24

Let x be the standard deviation away from the mean.

Since we know that,

Mean + Standard deviation * x = Value

Therefore putting the value we get,

18 +  4x = 24

Subtracting 18 both the side,

or, 4x = 24 -18

or, 4x = 6

Dividing by 4 both the side we get,

or, x = 6/4

or, x = 2.25

Hence,24 is 2.5 standard deviations away from the mean.

Answer:

c ≅ 35.4 cm.

Step-by-step explanation:

To find the length of the Hypotenuse of a triangle, the formula  a² + b² = c² will need to be used. Therefore:

26² + 24² = c² (c is the hypotenuse)

1252 = c²

√1252 = c

c ≈35.38

Round to tenths place:

c ≅ 35.4 cm. This is the Hypotenuse of the triangle.

Answer:

Number of child tickets = 9

Number of adult tickets = 36

Number of senior tickets = 27

Step-by-step explanation:

Given:

The ratio of adult tickets to child tickets = 4:1

Ratio of adult  tickets to senior tickets = 4:3

Number of total tickets = 72

Find:

The number of each ticket.

Computation:

Ratio between Adult to senior to child = 4:3:1

So,

Number of child tickets = [1 / (4+3+1)]Total tickets

Number of child tickets = [1 / (8)]72

Number of child tickets = 9

Number of adult tickets = [4 / (4+3+1)]Total tickets

Number of adult tickets = 36

Number of senior tickets = [3 / (4+3+1)]Total tickets

Number of senior tickets = 27

Find the distance between the two x values: -10 to -7 is 3 units, so add to the midpoint: -7 + 3 = -4

The x value is -4

Now do the same for y:

7 to -3 is 10 units

Because the midpoint is less than the end point subtract:

Y = -3 -10 = -13

Y = -13

The endpoint would be (-4, -13)

Answer:

A.400

Step-by-step explanation:

Well perimeter for a rectangle is l+l+w+w

100+100+l+l=600

200+2l=600

Subtract 200 from both sides

2l=400

Divide both sides by 2

l = 400 feet

The length of the rectangle is 400 feet long.

Answer:

The answer is D

Step-by-step explanation:

The solution would be like this for this specific problem:

Cost of the computer:

i = 0.117 / 12 

i = 0.00975 

= monthly payment 

= (i * P * (1 + i)^n) / ((1 + i)^n - 1) 

= (0.00975 * $1433 * (1 + 0.00975)^30) / ((1 + 0.00975)^30 - 1) 

= $55.32 

Electricity cost:

= $0.79 * 365.25 * 7 

= $2019.83 

Electricity Percentage: 

= $2019.83 / ($2019.83 + $1659.60) 

= 54.89% 

Electricity: 

= ($0.79 * 365 * 5) + ($0.79 * 366 * 2)

Electricity Percentage: 

= $2020.03 / ($2020.03 + $1659.60) 

= 54.898%

In total, the electricity made up 54.898% of the lifetime cost of the computer.

Answer:

(g + f)(x)

Step-by-step explanation:

the outputs of f(x) and g(x) will always have a sum of -1, which is h(x).

The expression of function H (x) is (g + f) (x).

Option 2 is true.

Here,

The function f (x) = -x - 4 and g(x) = x + 3

The value of H (x) is in the table is -1.

We have to find the expression to represents H(x).

What is Linear function?

A linear function is a simple function usually composed of constants and simple variables without exponents.

Now,

The function f (x) = -x - 4 and g(x) = x + 3

⇒( f + g ) (x) = f (x) + g(x)

                  = -x - 4 + x + 3

                  = -1

Which is same as the value of H (x) is in the table.

Hence, The expression of function H (x) is (g + f) (x).

Option 2 is true.

Step-by-step explanation:

The Triangle Inequality Theorem says that the sum of any two sides must be greater than the third side. Let's see if this is true.

a + c

9 + 9 = 18>1

c + b

9 + 1 = 10>9

True, the segments shown below could form a triangle. Option A is correct.

A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.

According to the Triangle Inequality theorem, any two sides' total must be bigger than the third side. Verify one by one;

⇒a + b>c

Factor the numerator

Critical points are

X =-3  X =2  X=7

We need to check the values when

(x cannot be 7 because then the denominator is zero)

and see when it is less than 0

Substitute a value in and see if factor is positive or negative

Answer:

Part A : y²(x + 2)(x + 4)

Part B: (x + 4) (x + 4)

Part C: (x + 4) (x - 4)

Step-by-step explanation:

Part A: Factor x²y²+ 6xy²+ 8y²

x²y²+ 6xy²+ 8y²

y² is very common across the quadratic equation , hence

= y² (x² + 6x + 8)

= (y²) (x² + 6x + 8)

= (y²) (x² + 2x +4x + 8)

= (y²) (x² + 2x)+(4x + 8)

= (y²) (x(x + 2)+ 4(x + 2))

= y²(x+2)(x+4)

Part B: Factor x² + 8x + 16

x² + 8x + 16

= x² + 4x + 4x + 16

= (x² + 4x) + (4x + 16)

= x( x + 4) + 4(x + 4)

= (x + 4) (x + 4)

Part C: Factor x² − 16

= x² − 16

= x² + 0x − 16

= x² + 4x - 4x - 16

= (x² + 4x) - (4x - 16)

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

= (x + 4) (x - 4)
