Answer:

30

Step-by-step explanation:

5x6=30

The design of the experiment is such that the knowledge of the type of

ball being hit does nit influence the outcome of the experiment.

Reasons:

The aim of the experiment is to determine if the new type of ball travels farther than the company's previous golf ball.

The design of the experiment is as follows;

Number of the previous golf ball in the experiment = 40

Number of the new type of golf ball used in the experiment = 40

The order in which the ball are selected from the bag = Randomly

The subject of the experiment = A golf pro

The sample size of each sample is larger than 30, and therefore, the

distribution can be taken as approximately normal.

The principle of comparison has been addressed in the experiment

because the golf pro that is subject to the treatment will react more

accurately to the change in the variable, given that, the previous golf ball

serves as a placebo in the study and after all the balls are hit, the distance

travelled by each set can be determined.

The correct option is therefore;

Answer:  None of the answers are viable.

Step-by-step explanation:

a ≅ 8b

a/b ≅ 8

A.  (3.1/2.5) = only slightly greater than 1

B.  2.5/3.1    = slightly less than 1

C.  (2/1.2) = less than 2

D.  1.2/2 = less than 1

None of these answers is viable.

None of the options are correct.

Given,

The number a is about 8 times greater than b.

We need to find the correct value of a and b from the given options.

A. a = 3.1 and b = 2.5

B. a = 2.5 and b = 3.1

C. a = 2 and b = 1.2

D. a = 1.2 and b = 2

We have,

2 times M = 2x M

2 greater than M = M + 2

2 less than M =  M - 2

Sum = adding

Times = Multiplication

Find the value of a and b.

We have,

The number a is about 8 times greater than b.

We can write it as

a = 8 x b

Find out which option is correct.

A. a = 3.1 and b = 2.5

a = 8 x b

3.1 = 8 x 2.5

3.1 ≠ 20

So this option is incorrect.

B. a = 2.5 and b = 3.1

2.5 = 8 x 3.1

2.5 ≠ 24.8

This option is not correct.

C. a = 2 and b = 1.2

2 = 8 x 1.2

2 ≠ 9.6

This option is not correct.

D. a = 1.2 and b = 2

1.2 = 8 x 2

1.2 ≠ 16

This option is not correct.

Thus none of the options are correct.

Answer:

6 and 28

Step-by-step explanation:

Question 8: Since the sum is atmost 16, the largest possible value of the number is available when the sum is 16. Then, we have 2x + 4 = 16, and that equals 2x = 12, which leads to x = 6.

Question 9. Since your bank value has to be above 525, and 814 dollars keep decreasing 10 each day, we know that it will stop at 534, because having 524 dollars will be below 525. Now, 814 - 534 = 280, and since you pay 10 every day, 280/18 = 28 days.

Answer:

There is no associative property of subtraction.

Step-by-step explanation:

Given:

x - (y - z) = 5 - (3 - 4) = 5 - (-1) = 5 + 1 = 6

(x - y) - z = (5 - 3) - 4 = 2 x -4 = -6

Therefore, there is no associative property of subtraction as 6 ≠ -6

Answer:

x = -2, y = -6

Step-by-step explanation:

(8x - 3y) + (-8x - 5y) = 2 + 46

-8y = 48

y = -6

8x - 3y = 2

8x - 3(6) = 2

8x + 18 = 2

8x = -16

x = -2

Answer:

[tex]\boxed { \sf (-2, -6) }}[/tex]

Step-by-step explanation:

We are asked to find the solution of the system of equations.

[tex]8x-3y=2\\-8x-5y=46[/tex]

When we solve systems of equations, we have to do 2 steps. The first step eliminates one variable so we can solve for the other. The next step helps us find the variable we canceled.

The first equation has the term 8x and the second equation has the term -8x. If these are added, they cancel, so we are left with the variable y. Add the equations together.

[tex](8x-3y=2) \\+ (-8x-5y=46)[/tex]

8x and -8x cancel, then add.

[tex](-3y=2)\\+ (-5y=46)[/tex]

___________

[tex]-8y= 48[/tex]

We are solving for y, so we must isolate the variable. It is being multiplied by -8. The inverse operation of multiplication is division. Divide both sides by -8.

[tex]-8y/-8=48/-8 \\y= 48/-8 \\y=-6[/tex]

Now we know what y is equal to, so we can plug it back into one of the original equations and solve for x.

I chose the first equation.

[tex]8x-3y=2[/tex]

[tex]8x-3(-6)=2[/tex]

[tex]8x+18=2[/tex]

Subtract 18 from both sides to isolate 8x.

[tex]8x+18-18=2-18\\8x=2-18\\8x=-16[/tex]

Divide both sides by 8.

[tex]8x/8=-16/8 \\x=-16/8 \\x= -2[/tex]

Coordinate points are written as (x,y) so our solution is (-2, -6)

Using proportions, it is found that they won 14 games after the first 16 games.

Hence, the rule of three is:

2 losses - 3 wins

12 losses - x wins

Applying cross multiplication:

[tex]2x = 3(12)[/tex]

[tex]x = \frac{36}{2}[/tex]

[tex]x = 18[/tex]

18 wins, being 18 - 4 = 14 after the first 16 games, hence, they won 14 games after the first 16 games.

Step-by-step explanation:

the triangle is an Isosceles triangle

let the another two angles be 2x

and apply angle sum property of triangle here

2x + 72° = 180

2x = 180 - 72

2x = 108

x = 108/2 = 54

therefore,

angle 2 = 54°

a/q

angle 2 = -9 + 7x

now,

54° = -9 + 7x

or

-9 + 7x = 54°

7x = 54 + 9 = 63°

x = 63/7 = 9

x = 9

therefore, value of x is 9.

In the system of equations, I am going to say that:

x is the number of dimes.

y is the number of nickels.

z is the number of pennies.

Two more nickels than dimes, thus:

Three times as many pennies as nickels, thus:

A dime is worth $0.1, a nickel is worth $0.05, and a penny is worth $0.01. Total of $0.52, thus:
