The correct answer which refers to the z-statistic for this data is b)0.90.

The hypothesis Test refers to the statistical approach where the test is applied to an assumption regarding a population parameter.

It is given that µ = 115 and Sigma = 30.

sample size is 25 with a mean of 120.4

The formular for z-statistic is

z = (x – u) / (σ / sqrt n)

Therefore, we input the values and we get

z = (120.4 – 115) / (30 / sqrt 25)

We calculate further and we get

z = 0.90

Therefore, the correct answer is option b.

The probability that the three they choose will consist of each of their favorite movies is 1/29791.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

It is given that:

Finn, Michael, and Chris are going to have a movie night this weekend. Together, they have 31 movies.

Total number of outcomes = 31

They choose three movies out of 31

Let us assume that  Finn, Michael, and Chris have 1 favorite movie out of 31.

The probability that the three they choose will consist of each of their favorite movies:

= (1/31)(1/31)(1/31)

= 1/29791

Thus, the probability that the three they choose will consist of each of their favorite movies is 1/29791.

Answer: change to inches:41 inches tall. 31 inches wide. perimeter:144 inches. perimeter insulation: costs $72

Step-by-step explanation:

Answer:

Step-by-step explanation:

Note: 1 foot is made up of 12 inches.

3 feet 7 inches = 3 * 12 + 7 = 36 + 5 = 41

2 feet 7 inches = 2 * 12 + 7 = 24 + 7 = 31

Part A

P = 2L + 2W                   Substitute the above Values into this equation

P = 2*41 + 2*31              Combine

P = 82 + 62                    Add

Answer: P = 144

Part B

1 inch costs 0.5 dollars

144 inches cost x

1/144 = 0.5/x              Cross Multiply

x = 144 * 0.5

Answer: x = 72 dollars

Answer:

x=-9

y=4

Step-by-step explanation:

x + 3y = 3

x - 5y = -29

Multiply the second equation by -1

-x + 5y = 29

Add the two equations together to eliminate x

x + 3y = 3

-x + 5y = 29

---------------------

0x +8y = 32

Divide each side by 8

8y/8 = 32/8

y = 4

Now solve for x

x+3y =3

x+3(4) = 3

x+12 = 3

Subtract 12 from each side

x+12-12 = 3-12

x = -9

Answer:

4/7

Step-by-step explanation:

1/4 divided by 7/16 is the same thing as 1/4 * 16/7. Multiply this and you will get the fraction of 16/28. Once simplified, this comes out to be 4/7.

Step-by-step explanation:

2000 <= (178 + S) + S

remember, they needed to collect at least 2000 cans.

S = the number of cans Shane collected.

the number of cans Abha collected is 178 more than S (the number of cans Shane collected).

and from there we get

2000 <= 178 + 2S

1822 <= 2S

911 <= S

so, the solution set is

S >= 911

and

Abha >= 1089

let's keep in mind that Profit = Revenue - Costs.

so each guitar costs originally "d" dollars online.

you buy the kits at half price, 50% of the original price, well, the original price is "d", half "d" is just 0.5d, and there's a shipping charge of $4.50.  So the Cost to get one kit alone for you is 0.5d + 4.50.

After some work, you resell the kits online for 1.5d + 4.5, so since that's the selling price that is your Revenue for one kit.

[tex]\stackrel{\textit{\Large Profit}}{\stackrel{Revenue}{(1.5d~~ + ~~4.50)}~~ - ~~\stackrel{Costs}{(0.5d~~ + ~~4.50)}}\implies 1.5d+4.5-0.5d-4.5 \\\\\\ 1.5d-0.5d+4.5-4.5\implies 1d\implies d[/tex]

The Pythagorean theorem states that the square on the hypotenuse is equal to the sum of the squares on the other two sides in a right triangle.

Pythagoras came up with a theorem that says, “the square of the hypotenuse of a right-angled triangle is equal to the sum of the square of the other two sides.” This theorem is known as the Pythagoras theorem.

Pythagorean theorem is a theorem in geometry that relates all the three sides of a right triangle.

It states that, in a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides.

A right triangle is a three-sided closed geometric plane figure in which one of the 3 angles is 900.

In a right triangle, the side opposite to the right angle is the longest side and is called the hypotenuse.

The horizontal side forming the right angle is called the base of the right triangle and the vertical side is the hypotenuse.

For example, if ΔABC is a right triangle with sides AB, BC, and AC such that the triangle is right-angled at B, then the Pythagoras equation is written as:

[tex]\rm Hypotenuse ^2= Base^2+ Perpendicular^2\\\\AB^2+BC^2=AC^2[/tex]

Hence, the Pythagorean theorem states that the square on the hypotenuse is equal to the sum of the squares on the other two sides in a right triangle.

Step-by-step explanation:

Let width be x

according to question

length = 2x-4

perimeter = 58

now,

perimeter = 2(length + width)

58 = 2(x+2x-4)

58 = 6x-8

6x = 66

x = 11

putting value of x in length

2x-4

= 2 X 11 -5

= 18

hence the dimensions of the rectangle is 18 and 11

Explain:

It is all because if you got an answer that you need to be between into it, you can start like this. For example: What number is between 3 and 4, well it's 3.5. So do that with the decimal, it's like the same thing.

What if it was between 3.4 and 3.6, than it's anywhere 3.51, like that, or 3.5, to make it simple.

The box plot represents the rate of cars in the Main Street per hour

25 percent of the time, the Main Street have 100 or more cars per hour

From the box plot, we have the following parameter:

The upper quartile of the boxplot is 100

This means that:

Q3 = 100

The upper quartile is the 75% dataset

The actual percentage is then calculated as:

Actual = 100% - 75%

This gives

Actual  = 25%

Hence, 25 percent of the time, the Main Street have 100 or more cars per hour

Answer:

Step-by-step explanation:

We need the circumference of the garden, with it's 150' radius.  Circumference, C,  is given by:  C = 2[tex]\pi[/tex]r.  I'll use [tex]\pi[/tex]=3.15, as you have requested, but it is actually closer to 3.14.

C = 2*(3.15)*150'

C = 945'

4 inches = 1/3 foot.

Every 1/3 of a foot of the circumference will have a flower.  We can make this a conversion factor:   3 flowers/foot

Flowers = (945')*( 3 flowers/foot) = 2835 flowers
