Answer:

The data is not appropriately normal.

Step-by-step explanation:

In inferential statistics, a normal distribution is said to be symmetric and should be single-peaked when working with a random selection of a large sample.

The high number of the sample is 100 which is further from other samples, the central limit theorem explains that the sample size of independent mean must be large enough to mimic the population for the sample to be normal or nearly normal. So, the sample is not appropriately normal and should be larger in size.

Answer: $8 for 1 hamburger

Step-by-step explanation:

Explanation:

The rule used here is

if sin(A) = cos(B), then A+B = 90.

In this case, B = 47, meaning that,

A+B = 90

A+47 = 90

A = 90-47

A = 43

Therefore,

sin(43) = cos(47)

Answer:

For 7m^2: 8.4

For .5m^2: .6

For 12 liters of paint: 10m^2

and for 6.6: 5.5m^2

Answer:

a) 8.4

b) 0.6

Step-by-step explanation:

a) 1.2L=1m^2

8.4L = 7m^2

7 times 1.2 is 8.4

b) 1.2L=1m^2

0.6L=0.5m^2

1.2 times 0.5 or 1.2 divided by 2 is 0.6

Answer:

21 dollars

Step-by-step explanation:

like my answer pls :)

Kevin will have to pay the amount of $21 for the necklace when the necklace is 40% off.

The percentage is defined as a ratio expressed as a fraction of 100.

Kevin wishes to purchase a $35 necklace for his mother. If the necklace is on sale for 40% off,

If the necklace is 40% off, Kevin will have to pay 60% of the original price, since 100 - 40 = 60.

To find out how much Kevin will have to pay, you can multiply the original price of the necklace by 60% and then divide the result by 100 to convert it to a dollar amount.

For example, if you multiply $35 by 60% and then divide by 100, you get:

($35 × 60%) / 100 = $21

Therefore, he will have to pay $21 for the necklace.

Step-by-step explanation:

The initial fee that the company charges is equivalent to $2.

Given is that a company rents bicycles to customers. The company charges an initial fee plus an hourly rate. This table shown in the question gives the total cost to rent a bicycle for different amounts of time.

Assume that the initial fee is equivalent to $x. Then we can write the charge function as -

C(x) = mx + c

Now -

C(x) = {(20 - 8)/(6 - 2)}x + c

C(x) = (12/4)x + c

C(x) = 3x + c

For (2, 8) , we can write -

8 = 3 x 2 + c

c = 8 - 6

c = 2

Therefore, the initial fee that the company charges is equivalent to $2.

Answer:

37 shots

Step-by-step explanation:

48% = 48/100

Set the ratios equal to each other so that we can find "x" the number of shots she made.

48/100 = x/78

78*48 = 3744

3744/100 = 37.44

She made 37 shots

Answer:

[tex]x=4[/tex]

Step-by-step explanation:

We have the function:

[tex]f(x)=-2(x-4)^2+2[/tex]

This is a quadratic in vertex form:

[tex]f(x)=a(x-h)^2+k[/tex]

Where (h, k) is the vertex.

So, according to the equation, h=4 and k=2.

Hence, our vertex is at (4, 2).

Remember that the axis of symmetry is the vertical line that passes through the x-coordinate of the vertex.

Hence, our axis of symmetry is x=4.

Answer:

$12

Step-by-step explanation:

Lola has x.

Mary-Ann has 2 1/3 times Lola's amount, so Mary-Ann has (2 1/3)x.

Mary-Ann has $28.

(2 1/3)x = 28

7/3 x = 28

Multiply both sides by 3/7.

x = 28 * 3/7

x = 12

Lola has $12.

Answer:

C. 10

Step-by-step explanation:

You can take the blank as x

so 361.2 / x = 36.12

multiply by x

361.2 = 36.12x

divide

x = 10

Answer:

C. 10

Step-by-step explanation:

When dividing a number by 10, you are moving the decimal place to the left by one placing.

361.2/10 = 36.12

Simply move the decimal from between 1 and 2 to between 6 and 1.
