A salesman sells cars with prices ranging from $5,000 to $45,000. the histogram shows the distribution of the numbers of cars he

Sauron [17]

In the given histogram, the shape of the histogram shows that the shape of the distribution exhibits symmetry (i.e. the shorter bars are to the left and to the right while the longer bars are in the middle). Adding the sales of cars priced under $5,000 and cars priced $45,000 to $50,000 with projected sales of 200 cars for each category will result in adding bars of the same size as the shortest bar to both ends of the histogram. This will not affect the initial shape of the distribution in the histogram as the distribution will still exhibit symmetry. Therefore, the correct answer to the question is "the distribution will exhibit symmetry<span>" (option a).</span>

Mickey used these calculations to find how much he would spend on 7 cartons of eggs, if 12 cartons of eggs cost $22.20. Describe

timofeeve [1]

Mickey incorrectly calculated the unit price:
$\frac{12}{22.20} = 0.54$

The correct operation is:
$\frac{22.20}{12} = 1.85$

Each carton costs 1.85, so 7 cartons cost
$1.85 \times 7 = 12.95$

Find the number c that satisfies the conclusion of the Mean Value Theorem on the given interval. (Enter your answers as a comma-

coldgirl [10]

Answer:

c is all the points in the open interval (0,25)

Step-by-step explanation:

Here given is a function

$f(x) =x$ , which is continuous in the interval [0,25] and differentiable in (0,25)

Mean value theorem says there exists at least one c in the interval (0,25) such that

$f'(c) = \frac{f(25)-f(0)}{25-0}$

We have

$f(25)=25 and f(0) = 0\\f'(c) = 1$

For the given function

$f'(x) =1$

Hence we have c equals all the points in the open interval (0,25)

A nature center offers 2 guided walks. The morning walk is two-third mile. The evening walk is three-sixths mile. Which walk is

MArishka [77]

Answer:

Evening walk is shorter.

Step-by-step explanation:

We have been given that a nature center offers 2 guided walks. The morning walk is two-third mile. The evening walk is three-sixths mile. We are asked to find the shorter walk.

Let us compare both fractions by making the same denominator.

$\text{Two-thirds}=\frac{2}{3}$

$\text{Two-thirds}=\frac{2\times2}{3\times2}$

$\text{Two-thirds}=\frac{4}{6}$

$\text{Three-sixth}=\frac{3}{6}$

Upon making common denominator, we can see that two-thirds are equal to four sixths.

Since three-sixths is less than four-sixths, therefore, evening walk is shorter.

We will draw two rectangles, one with 6 sub-parts and other with three sub-parts.

We will shade 2 parts out of 3 sub-parts to represent 2/3 and shade 3 parts out of 6 sub-parts to represent 3/6.

Then we will further divide three sub-parts into 6 sub-parts as shown in the diagram that will represent 4/6.
