HURRY I GOT 30 MINS
A company that manufactures golf balls produces a new type of ball that is supposed to travel significantly farther than the company’s previous golf ball. To determine this, 40 new-style golf balls and 40 original-style golf balls are randomly selected from the company’s production line on a specific day. The balls are then placed in a bag and shaken. A golf pro then selects a ball and hits it. The distance the ball travels is then measured. The bag is shaken again, and the golf pro selects another ball to hit. She continues this procedure until all 80 of the golf balls are hit.

Has the principle of comparison been addressed in this experimental design?

A Yes, because the balls are randomly selected, the distances of the new ball can be compared to the distances of the original ball.
B Yes, because the original ball type is included in this experiment, the distances the different balls travel can be accurately compared.
C No, because a placebo ball was not used, a comparison cannot be made to determine if the new ball travels significantly farther.
D No, because all of the new type of balls are not hit first, the distances they travel cannot be compared to the distances of the original ball.

A graph is referred to as a mathematical construct that connects a collection of points to express a certain function. A pairwise link between the items is established using it. The lines that link the graph's vertices (also known as nodes) are its vertices (lines).

A common technique for graphically showing data linkages is the graph. Although takes up less space, a graph accomplishes the goal of conveying which is either too many more and complicated to be completely stated in the words.

Answer:

a. E(a) = (a+1)²

b. E(a + h) = (a+h+1)²

c. E(a + h) - E(a) / h = (a+h+1)²- (a+1)²/h

Step-by-step explanation:

E(z)=(z+1)²

E(a) = (a+1)²

E(a + h) = (a+h+1)²

E(a + h) - E(a) / h = (a+h+1)²- (a+1)²/h

Answer:

50c + 120m represents Mia's earnings with c commercials and m movies

Mia would earn $610 with 5 commercials and 3 movies

Step-by-step explanation:

First, create an expression that represents her earnings with c commercials and m movies:

50c + 120m will represent her earnings with c commercials and m movies

Now, find her earnings with 5 commercials and 3 movies:

50c + 120m

50(5) + 120(3)

= 250 + 360

= 610

So, Mia would earn $610

Answer:

$610

Step-by-step explanation:

Ok so I would multiply $50 with 5 because it costs $50 for one commercial and there are 5 of them. You get $250 from it.

Next you multiply $120 and 3 because it costs $120 for 3 movies. You get $360.

Now you add and you get your answer which is $610.

Answer:

-1/4

Step-by-step explanation:

Points: (-8, -3), (-24, 1)

slope = rise/run = difference in y / difference in x

Find the difference in the y-coordinates in either order:

Let's do 1 - (-3) = 1 + 3 = 4

Now we find the difference in x, but it must be in the same order we did the difference in y.

-24 - (-8) = -24 + 8 = -16

Difference in y = 4

Difference in x = -16

slope = 4/(-16) = -1/4

Answer: -1/4

Answer:

m∠A = 78°

Step-by-step explanation:

The question tells us these angles are supplementary meaning they will add up to 180°. We can use the information to make an equation.

m∠A + m∠B = 180

3x + 18 + 5x + 2 = 180

8x + 20 = 180

8x = 160

x = 20

Now we can substitute the solution for x to find the measure of ∠A.

m∠A = 3(20) + 18

m∠A = 60 + 18

m∠A = 78

x=y-8;5x+y=-4

Step: Solve x=y−8for x:

Step: Substitute y−8 for x in 5x+y=−4:

5x+y=−4

5(y−8)+y=−4

6y−40=−4(Simplify both sides of the equation)

6y−40+40=−4+40(Add 40 to both sides)

6y=36

6y /6 = 36/ 6  (Divide both sides by 6)

y=6

Step: Substitute6foryinx=y−8:

x=y−8

x=6−8

x=−2 (Simplify both sides of the equation)

x=−2 and y=6

Answer:

The value of x = √6/2

Step-by-step explanation:

Given

The hypotenuse of triangle = √2

Ф = 30°

Using the trigonometric ratio

cos Ф = adjacent / hypotenuse

here

Ф = 30°

Adjacent to 30° = x

hypotenuse = √2

so substituting

cos Ф = adjacent / hypotenuse

cos 30° = x / √2

x = √2 × cos 30°

x = √2 × √3 / 2

x = √6/2

Therefore, the value of x = √6/2
