Answer:

it will cost $255.

Step-by-step explanation:

225.

a product that normally costs $500 with a 55 percent discount will cost you $225.00, and you saved $275.00. You can also calculate how much you save by simply moving the period in 55.00 percent two spaces to the left, and then multiply the result by $500 as follows: $500 x . 55 = $275.00 savings.

Answer:

Step-by-step explanation:

The standard form is (x - h)2 = 4p (y - k), where the focus is (h, k + p) and the directrix is y = k - p. If the parabola is rotated so that its vertex is (h,k) and its axis of symmetry is parallel to the x-axis, it has an equation of (y - k)2 = 4p (x - h), where the focus is (h + p, k) and the directrix is x = h - p.

Answer:

m∠B = 105°

Step-by-step explanation:

Given

We know that the sum of angles in a triangle = 180°

A + B + C = 180°

x + 5 + 3x + x = 180°

5x + 5 = 180°

5x = 180° - 5

5x = 175

x = 175 / 5

x = 35

Thus, the measure of ∠B will be:

m∠B = 3x

         = 3(35)

         = 105°

m∠B = 105°

Answer:the answer would be 8.

Step-by-step explanation:

If you look at the reduced triangle, the height is 2. Therefore you would have to multiply by 4 instead of 0.4 even if the scale factor is 0.4. The reason is, you are enlarging the triangle to find the bigger triangle. If you did 0.4 times 2 you would get 0.8. But that wouldn’t make any sense if you said that that was the height of the ENLARGED triangle.

8

Answer:

$81.94

Step-by-step explanation

I would subtract 5.95 to 75.99 first and get a total of 70.04 and put it off to the side then I would find out what 7.5 of the total purchase is (75.99) and that is 5.70 rounded and in the paragraph it said "whatever one is bigger" and in this case the 5.95 is bigger so you would add that to your total and get $81.94

mean annual income =  $13,646.35

median annual income = $3,650

The median is a better measure of center

=======================================================

Explanation:

If you earn $10 a day, and do so for 365 days, then you earn 365*10 = 3650 dollars per year.

If there are 999 employees earning this amount, then the amount earned is 999*3650 = 3,646,350

Add on the 10,000,000 to get

10,000,000+3,646,350 = 13,646,350

The total amount earned is $13,646,350

Divide this over the 1000 people (999 workers + 1 boss)

We get: (13,646,350)/(1,000) = 13,646.35

The mean is annual income is $13,646.35

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

The median is the middle most value. If you list out the pay amounts of just the workers, you'll get the list:

{3650, 3650, 3650, ..., 3650}

We will have 999 copies of 3650 listed out. You don't have to list all 999 of them. Just a few is a good start. The three dots indicate the pattern goes on until we reach the 999th item.

If we then tack on the overseer's pay, then we have the list

{3650, 3650, 3650, ..., 3650, 10 million}

I'm using "million" instead of the digits to avoid using commas here.

The middle won't change due to one item being tacked onto the end. The middle is going to be 3650 either due to it being part of the set, or we find the midpoint between 3650 and 3650, which averages out to 3650.

The median income is $3,650

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

The median income is the better measure of center because it represents where the workers are instead of some distant "midpoint" between the workers and the boss. No person is making $13,646.35 a year. They are either making $3,650 or they are making $10,000,000. There's nothing in between. So it's better go lean toward the larger group when deciding where the center should go. Think of it like a balance beam or a see-saw.

As you can see the median is not affected by outliers. We can change the "ten million" to something like "a hundred million" and the median would still be the same. I recommend you compute the mean if the overseer earns 100 million dollars, and you'll find the mean will increase dramatically. However, the median will stay where it's at. The only time the median will change is if we introduce elements that are somewhere around (either higher or lower) than 3650, and these values are close to 3650. But this won't change the center very much compared to the drastic changes the mean undergoes due to such a large outlier.

The general rule of thumb is: a large outlier to the right pulls the mean to the right. An outlier to the left pulls the mean to the left. In this case, the mean is pulled to the right. The data is skewed to the right (or positively skewed).

So again, the conclusion is that the median is the better measure of center.

Answer:

0.40166

Step-by-step explanation:

When given random number of samples, we solve using the z score formula:

z = (x-μ)/σ/√n where

x is the raw score= 161

μ is the population mean = 162.4

σ is the population standard deviation = 15.9

n is random number of samples = 8

Hence,

z = 161 - 162.4/15.9/√8

z = -0.24904

Probability value from Z-Table:

P(x<161) = 0.40166

The probability that the mean of 8 randomly selected scores is less than 161 is 0.40166

Two equivalent ratios for a proportion

To determine whether the two ratios form a proportion, you can compare them using a common denominator

1x7 = 7

2x7 = 14

7/14 = 7/14

Answer:

Option (D)

Step-by-step explanation:

Let the equation of the given line is,

y = mx + b

m = slope of the line

b = y-intercept

From the graph attached,

Slope 'm' = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

m = [tex]\frac{-5}{1}[/tex] = -5

y-intercept of the given line = -2

Therefore, equation will be,

y = -5x - 2

Option (D) is the correct option.

Answer:

It's true,

Answer:

it is 862.5

Step-by-step explanation:

each inch is 115 miles, so if theres two inches theres double the amount that there would be if there was 1 inch, so if theres 7 inches then you would have 7 times the amount it would be if there was 1 inch, in this situation theres 7.5 so you would multiply the 115 miles by 7.5 becuase that's how many inches there is, so multiplying that is the same as adding 115 plus 115 plus 115, and so on till you get the amount you need. did this help?
