Answer: 0.670

Step-by-step explanation:

Given that :

Population mean (μ) = 11.5

Sample size, n = 22

Sample mean, x = 11.7

Standard deviation, s = 1.4

The test statistic ;

Tstat = (x - μ) / (s/√n)

Tstat = (11.7 - 11.5) / (1.4/sqrt(22))

Tstat = 0.2 / 0.2984810

Tstat = 0.6700594

Tstat = 0.670 (3 decimal places )

Answer:

x = 4

Step-by-step explanation:

(10x + 9) + 34 + 97 = 180

10x +140 = 180

10x = 40

x = 4

The value of x in the given angles of the traingle CAB for angle m∠A is determined as 4.

The sum of angles in a triangle can be used to determine the value of x in the given angles above.

m∠A + m∠B + m∠C  = 180 (sum of angles in a triangle)

10x + 9 + 34 + 97 = 180

10x + 140 = 180

10x = 40

divide both sides by 10;

x = 40/10

x = 4

Thus, the value of x in the given angles of the traingle CAB for angle m∠A is determined as 4.

Answer:

4.99 + 1.99m = T. Dependent Variable = T (Total Cost), Independent Variable = M (Movies) Now, for the equation we have to input 5 for the m because he watched 5 movies. So, 4.99 + 1.99(5) = T Well, 1.99 x 5 is 9.95 so our next step is this 4.99 + 9.95 = T and that  added up together would be 14.94 dollars. $14.94 = T

Answer:

k=9

Step-by-step explanation:

8k-6=(k+3)+6k first remove the unnecsarry parentheses which would make it 8k-6=k+3+6k

then collect the like terms and get 8k-6=7k+3 then move the variable to the left and change its sign to get 8k-7k-6=3.

then collect the like terms a final time which would get you k=3+6 to then get k=9

Answer:

Step-by-step explanation:

The given quantities of ingredients are required for making tomato soup for 4 people. To make soup for 14 people, the multiplicative factor can be determined by;

[tex]\frac{14}{4}[/tex] = 3.5

Thus, the quantities of ingredients needed to make soup for 14 people are:

6 tomatoes x 3.5 = 21 tomatoes

1 potato x 3.5 = 3.5 potato

1 onion x 3.5 = 3.5 onions

2 table spoons of olive oil x 3.5 = 7 table spoons of olive oil

2 pints of vegetable stock x 3.5 = 7 pints of vegetable stock

1 carrot x 3.5 = 3.5 carrots

4 slices of bread x 3.5 = 14 slices of bread

The quantity of ingredients needed to make soup for 14 people are:

21 tomatoes

3.5 potato

3.5 onions

7 table spoons of olive oil

7 pints of vegetable stock

3.5 carrots

45

Step-by-step explanation:

Because a triangle always has a 180 degree total, we know how to find the answer. Since there is 90 used already, there is only 90 left with 2 points. So we divide the 90 by 2 and get 45 degrees as our answer.

Answer:

40people

Step-by-step explanation:

Let the number of those that owned a dog be x

Let the number of those that owned a cat be y

If the number of people who own a dog is four times the number of people who own a cat, then:

x = 4y

Since x+y =100

4y+y = 100

5y = 200

y = 200/5

y = 40

x = 4(40)

x = 160

Hence 40 people surveyed own a cat

Answer:

c = 0.59x + 275

Step-by-step explanation:

If x represents number of miles than $0.59 per mile fits in with that x. This would make it $0.59x.

As for the $275, its stated in text plus $275 so that would make it

$0.59 x + $275.

With this we can see its c = $0.59x + $275.

This was my way of thinking of how I looked at the text, I cant confirm if the way I explained it is correct.

Answer:

1. 62.5

2. 66.25

Step-by-step explanation:

25% of 50 is 12.5 add that to 50 is 62.5

6% of 62.5 is 3.75 so 3.75+62.5 is 66.25

Answer:

A. The selling price is [$62.5]

B. The total cost is [$66.25]

Step-by-step explanation:

25% of 50 is 12.5, and if you add that to 50 is 62.5

6% of 62.5 is 3.75 so 3.75+62.5 is 66.25
