Answer:

8 to the power of 4

Step-by-step explanation:

since their are four 8, (8x8x8x8) , you have to put that into an exponent

still need proof?

8x8x8x8=4096

8 to the power of 4 = 4096

so to conclude, 8 to the power of 4 is the same thing as saying 8x8x8x8, it is jsut the exponent version

Answer:

Yes it is

Step-by-step explanation:

Answer:

The answer is A linear model is a good fit for data set b but not data set a

Step-by-step explanation:

It can be concluded that data set A is linear, and data set B is not linear.

        [Y] = a + b[X] + ɛ

Given is that residuals for data set A and data set B were calculated and plotted on separate residual plots.

If the residuals for data set [A] form a pattern and the residuals for data set [B] do not form a pattern than it can be concluded that data set A is linear, and data set B is not linear.

Step-by-step explanation:

4 students is 20% ,8 students is 40%, 12 students 80%, 16 students 100%

The solution to the equation 1/2a + 2/3b = 50 when b = 30 is a = 60

The equation is given as

1/2a + 2/3b = 50

The value of b is given as

b = 30

So, we have

1/2a + 2/3 * 30 = 50

Evaluate the product

So, we have

1/2a + 20 = 50

Evaluate the like terms

So, we have

1/2a = 30

Multiply both sides by 2

a = 60

Hence, the solution to the equation 1/2a + 2/3b = 50 when b = 30 is a = 60

Answer:

Therefore, the correct answer is 24,069,100.

Step-by-step explanation:

(6.91 x 10^4) = 6.91 x 10,000 (10 x 10 x 10 x 10) or 69,100.

(2.4 x 10^7) = 2.4 x 10,000,000 (10 x 10 x 10 x 10 x 10 x 10 x 10) or 24,000,000.

24,000,000 + 69,100 = 24,069,100

Therefore, the correct answer is 24,069,100.

Answer: x=-1°

Step-by-step explanation:

m∠LMP=x°+73°     m∠PMN=81°+x°     m∠LMN=152°      x=?

m∠LMP+m∠PMN=m∠LMN

x°+73°+81°+x°=152°

2x°+154°=152°

2x°+154°-154°=152°-154°

2x°=-2°

Divide both parts of the equation by 2:

The length of AB after dilation is 3/5cm.

The size by which the shape is enlarged or reduced is called as its scale factor.

Scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape.

It is used to increase or decrease the size of an object.

The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.

For example, a rectangle has a length of 5 units and a width of 2 units. Now, if we increase the size of this rectangle by a scale factor of 2, the sides will become 10 units and 4 units, respectively. Hence, we can use the scale factor to get the dimensions of the changed figures.

Given:

Length of AB = 3 cm

scale factor = 1/5

As, we know

scale factor = change in length / Actual length

1/5 = Change in length / 3

Change in length = 3/5

Hence, the length of AB after dilation is 3/5 cm

On factorizing 3y⁻⁴ + y⁻⁵ with the given factor y⁻⁵ we get y⁻⁵(3y + 1 ).

Factorization of the polynomial refers to the process of expressing the polynomial as a product of two or more factors.

For Example ; the factors of x²-16 can be written as (x+4)(x-4).

In the given question

(3y⁻⁴ + y⁻⁵)  

the common factor y⁻⁵ is given

we have to factorize using the common factor .

taking y⁻⁵ common from both the terms we get

= y⁻⁵(3y⁻⁴/y⁻⁵ + 1 )

=y⁻⁵(3y⁻⁴⁺⁵ + 1 )

=y⁻⁵(3y¹ + 1 )

=y⁻⁵(3y + 1 )

Therefore , On factorizing 3y⁻⁴ + y⁻⁵ with the given factor y⁻⁵ we get y⁻⁵(3y + 1 ).

Answer:

34.5 ft squared

Step-by-step explanation:

Split the figure into a triangle and two rectangles. The two vertical lines on the figure already do that. The triangle's area is 3*3/2 because 8 - 3 - 2 = 3 is the base and the height is 3. Use b * h/2. The area of the smaller rectangle is 2 *3. The area of the larger rectangle is 8 * 3. Add the areas up: 4.5 + 6 + 24 = 34.5.

The equation will be F = 3x. Then the force required to compress the spring 8 ​inches will be 24 pounds.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

A spring's length directly relates to the amount of force needed to compress it.

Let F be the force and x be the compressed length. Then the equation will be

F ∝ x

F = kx

If a force of 15 pounds is required to compress a certain spring 5 ​inches. Then the value of the variable k will be

15 = 5k

k = 15/5

k = 3 pounds per inch

Then the equation will be

F = 3x

The force required to compress the spring 8 ​inches will be

F = 3 (8)

F = 24 pounds

The force required to compress the spring 8 ​inches will be 24 pounds.

For

Canada = 26 days

Italy = 42 days

USA = 13 days

Find:

Z scores

Computation:

Z scores = [X-μ]/σ

For Canada

Z scores = [26-29.4]/8.6

Z scores = -0.3953

For Italy

Z scores = [42-29.4]/8.6

Z scores = 1.46511

For USA

Z scores = [13-29.4]/8.6

c is the correct answer

Answer:

x'1 = -1

x'2 = 8

Step-by-step explanation:

Answer:

x = - 1, x = 8

Step-by-step explanation:

Given

x² - 7x - 8 = 0 ( add 8 to both sides )

x² - 7x = 8

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- [tex]\frac{7}{2}[/tex] )x + [tex]\frac{49}{4}[/tex] = 8 + [tex]\frac{49}{4}[/tex] = [tex]\frac{81}{4}[/tex]

(x - [tex]\frac{7}{2}[/tex] )² = [tex]\frac{81}{4}[/tex] ( take the square root of both sides )

x - [tex]\frac{7}{2}[/tex] = ± [tex]\sqrt{\frac{81}{4} }[/tex] = ± [tex]\frac{9}{2}[/tex] ( add [tex]\frac{7}{2}[/tex] to both sides )

x = [tex]\frac{7}{2}[/tex] ± [tex]\frac{9}{2}[/tex]

Thus

x = [tex]\frac{7}{2}[/tex] - [tex]\frac{9}{2}[/tex] =  [tex]\frac{-2}{2}[/tex] = - 1

x = [tex]\frac{7}{2}[/tex] + [tex]\frac{9}{2}[/tex] = [tex]\frac{16}{2}[/tex] = 8
