Carlos and Lily want to know the combined amount of money they made last week. They both made $12 per hour, but Carlos also made a $35 bonus. Carlos says the combined amount is 12C + 35 + 120 where Cis the number of hours he worked, and L is the number of hours Lily worked. Lily says the combined amount is 12(C+ L) + 35. Who is right? Explain.

Answers

Answer:

Lily is right

Step-by-step explanation:

Carlos made:

12C + 35

Lily made:

12L

Together they made:

12C + 35 + 12L = 12(C + L) + 35

Lily is right. We don't know what 120 means in Carlos's equation, he should put 12L for Lily.

Melvin is pushing a tire during workout with the dimensions shown how many square inches of space has a tire covered after Melvin pushes the tire 5 times around

Answers

Answer:

The answer is below

Step-by-step explanation:

The question is not complete, but I would show you how to solve it.

Solution:

A circle is the locus of a point such that its distance from a fixed point which is its center is always constant.

The tire has the shape of a circle. Therefore the distance the tire covers if it is pushed around once is the same as the circumference of the tire. The circumference is given by:

Circumference = 2πr; where r is the radius of the tire

Let us assume that the tire has a radius of 7 cm. Hence:

Circumference = 2π(7) = 44 cm

If the tire moves around 5 times, the distance covered = 5 * circumference of tire = 5 * 44 cm = 220 cm

How do you do this C=2πr with π=3.14?

Answers

Answer: C=2*3.14*r

Step-by-step explanation:

You just plug in 3.14 for pi, it's pretty simple

Question 4 0
A two-sample t-test for a difference in means was conducted to investigate whether defensive players on a football team can bench-press more weight, on average, than
offensive players. The conditions for inference were met, and the test produced a test statistic of t = 1.083 and a p-value of 0.15.
Based on the p-value and a significance level of a = 0.05, which of the following is the correct conclusion?
Submit
Reject the null hypothesis because 0.15 > 0.05. There is not convincing evidence that defensive players can bench-press more weight, on average, than
offensive players.
B
Reject the null hypothesis because 0.15 > 0.05. There is convincing evidence that defensive players can bench-press more weight, on average, than
offensive players
с
Fail to reject the null hypothesis because 0.15 > 0.05. There is not convincing evidence that defensive players can bench-press more weight, on average,
than offensive players,
D
Fail to reject the null hypothesis because 0.15 > 0.05. There is convincing evidence that defensive players can bench-press more weight, on average,
than offensive players
Fail to reject the null hypothesis because 0.15 > 0.05. There is convincing evidence that defensive players can bench-press the same amount of weight,
on average, as offensive players.

Answers

Answer:

Fail to reject the null hypothesis because 0.15>0.05

. There is not convincing evidence that defensive players can bench-press more weight, on average, than offensive players.

Step-by-step explanation:

Since P>a we can not reject the null hypothesis. We cannot conclude the alternative hypothesis in context.

3. Which of the following equations would not have a solution that is the same as the solution to the system
shown below
2x + 3y = 1. x-y=5
(1) 3x+2y=6
(3) 5y=-9
(4) 2x-2y=5
(2) 4x+6y=2

Answers

Answer:

A

Step-by-step explanation:

The solution that is not the same as the solutions to the system of equations is 2x - 2y = 5.

What is a solution?

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

2x + 3y = 1 _____(1)

x - y = 5 _______(2)

From (1) and (2) we get,

x = 5 + y

2 (5 + y) + 3y = 1

10 + 2y + 3y = 1

10 + 5y = 1

5y = -9

y = -9/5

Now,

x = 5 - 9/5

x = (25 - 9)/5

x = 16/5

The solutions are x = 16/5 and y = -9/5.

Now,

(1) 3x + 2y=6

3 x (16/5) + 2 x (-9/5) = 6

48/5 - 18/5 = 6

30/5 = 6

6 = 6

(2) 5y = -9

5 x (-9/5) = -9

-9 = -9

(3) 2x - 2y = 5

2 x (16/5) - 2 x (-9/5) = 5

32/5 + 18/5 = 5

50/5 = 5

10 ≠ 5

(4) 4x + 6y = 2

4 x (16/5) + 6 x (-9/5) = 2

64/5 - 54/5 = 2

10/5 = 2

2 = 2

Thus,

3x+2y=6, 5y=-9, and 4x+6y=2 have the same solutions.

Step-by-step explanation:

Let's look at this pattern. Something I immediately saw was that every time, the previous fraction gets added by 1. -3/2 +1 is -1/2, -1/2 +1 is 1/2, and so on. So the next three terms would be 7/2, 9/2, and 11/2.

Step-by-step explanation:

The number of degrees did it rotate altogether should be considered as the 150 degrees.

Calculation of the number of degrees:

Since A sprinkler rotates 75°, pauses, and then rotates another 75

So, here total degrees be like

= 75 degrees + 75 degrees

= 150 degrees
