Answer 2

A test statistic is a statistic that is used to test statistical hypotheses. The test statistic of the given hypothesis is; C: -0.25

What is the test statistic?

A test statistic is a statistic that is used to test statistical hypotheses. A test statistic is a numerical summary of a data set that lowers the data to a single number that can be used to perform the hypothesis test.

As it is given to us that the sample mean(x') is 36.63 hours, while the standard deviation(σ) is 13.23.

Now, we want to know whether Americans work less than 40 hours or not. therefore, let's first define the hypothesis;

Alternative Hypothesis; μ < 40

Null Hypothesis; H₀: μ ≥ 40

Further, the Formula for test statistics is given,

[tex]z = \dfrac{(x'-\mu)}{\sigma}\\\\z = \dfrac{(36.63- 40)}{13.23}\\\\z = -0.25[/tex]

Hence, the test statistic of the given hypothesis is; C: -0.25.

You sit in the bleachers at a concert. The angle of depression from your horizontal sight to the stage is 24 degrees. If your seat is 45 feet above the stage level what is your actual distance d from the stage

Answers

Answer:

x=111ft

Step-by-step

sin 24 = 45/x

+ the parallel lines

45 +x+24

x= 45/sin 24

The actual distance of your from the stage is 111 feet.

What is angle of depression?

The angle formed by the line of sight and the horizontal plane for an object below the horizontal is called angle of depression.

What is sine of an angle?

The sine (sin) of an acute angle in a right angled triangle is the ratio between the side opposite the angle and the hypotenuse of the triangle.

According to the given question

We have

Angle of depression = 24degrees.

Let d be the actual distance of your from the stage.

Now in right angle triangle ABC

We have

AC = 45 feet

And, ∠ABC = 24 degrees

Now the Sine of an angle ∠ABC is given by

[tex]sin24 = \frac{AC}{AB}[/tex]

⇒[tex]sin24=\frac{45}{d}[/tex]

⇒ [tex]0.406=\frac{45}{d}[/tex]

⇒ [tex]d =\frac{45}{0.406}[/tex]

⇒[tex]d = 110.64 feet[/tex] or [tex]111feet[/tex]

Hence, the actual distance of your from the stage is 111 feet.

Did you know it takes about 40 pounds of olives to make 3 liters of olive oil? Orchard A grew about 2000 pounds of olives. How many liters of olive oil would this make?

Answers

Answer:

150

Step-by-step explanation:

Using the unitary method,we can say that 150  liters of olive oil it will make.

What is unitary method?The unitary method is a technique in mathematics for solving a problem by finding the value of a single unit, I.e.,1,(by dividing) and then finding the necessary value by multiplying the single unit value.A method of solving a problem that involves first determining the value of a single unit,And then multiplying that value to determine the required value.

According to the question,

40 pounds of olives to make 3 liters of olive oil.2000 pounds of olives will make 150  liters of olive oil.    3/40= 0.075 0.075 * 2000150

Which inequality is graphed below?


Answers

Answer:

The answer is the last one or the one on the very bottom because y is above and touching the line so y must be greater than or equal to the slope plus the y-intercept or b. I figured out the slope by using rise over run meaning that you must first go up or down on a coordinate and then go left or right to meet the other coordinate. The y-intercept is just the place where the line touches the y axis and that is on -1. By piecing up these pieces of information one by one you will get D or the last one.

1, You need to find LCD for every fraction add or subtract question

2, 3/4 + 6/10.

LCD: 20,

4 x 5=20 and times 3 by 5 to get 15 (15/20),

10 x 2 =20 and 6 times 2 to get 12 (12/20).

Now you may add them together which is 12/20 + 15/20= 27/20, simplify:

1 7/20

3, 1/6 + 1/4.

LCD: 12

6 x 2= 12, 1 x 2=2 (2/12)

4 x 3= 12, 1 x 3=3 (3/12)

add, now 5/12

the whole was 12/12 of pie so now subtract

12/12 - 5/12= 7/12

4, 1/6 + 2/5 + 1/3.

LCD: 30

6 x 5=30, 1 x 5= 5 (5/30)

5 x 6= 30, 2 x 6=12 (12/30)

3 x 10= 30, 1 x 10= 10 (10/30)

add, 5 + 12 + 10= 27 (27/30)

simplify: 9/10

5, 14/25 + 1/5.

LCD: 25

  13. correct

Step-by-step explanation:

In general, it is a good idea to write a statement that answers the question asked. Simply solving an inequality for "x" rarely answers the question (unless it is a question that asks for the value of "x"). It is often best to try to use the wording that the question uses.

It is also a good idea to say what your variable represents.

__

10.

The required relation is "cheaper than" so the "or equal to" case does not apply. The variable represents messages, so the solutions will be integers.

  "Nadine can send and receive more than 33 messages so the unlimited plan is cheaper."

__

11.

"Becky can afford at most 8 fish."

__

12.

"Loretta must drive more than 260 miles farther to reach Pensacola."

__

13.

"Terri can spend at most 35 minutes listening to music."

Additional comment

The wording of the question in problem 10 is unconventional, but we have elected to use it anyway in the above answer. We could write "The unlimited plan is cheaper if Nadine sends and receives a total of more than 33 messages."
