When would you choose to use a histogram to represent data?

1 answer:

4 0

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins. Bar charts, on the other hand, can be used for a great deal of other types of variables including ordinal and nominal data sets.

A certain factory produces and sells 8000 cars per month, making a monthly net profit of P dollars. They sell

vredina [299]

Answer:

p= 8000n-8000c

Step-by-step explanation:

8000

p= n - c

p= 8000n-8000c

Esentially you need to subtract n, the amount they sell each car for by c, the amount it costs to produce a car, <em>(which should be less because the company has to make money)</em><em> </em>this would give you the total they make a month, P.

Because the amount of cars is constant, 8000, you can always multiply the cost of the car and how much its sold for by 8000. Otherwise, you would have another variable like k, which would be how many cars sold

Miss Rosener will be attending a Doctor Who Halloween Party this year, and she wants to make fez hats for all of the guests. She

Elis [28]

Answer:

15 fezzes

Step-by-step explanation:

1. Okay, so first you want to convert the yards of felt to inches to make the math easier. There are 36 inches in a yard so multiply 3 3/4 × 36.

To do this you should convert the fraction to improper.

3 3/4 = 15/4

ok so now multiply to turn it into inches.

15/4 × 36 = 540/4

now just simplify

540/4 = 135

2. So now that you know that she has 135 inches of felt all you have to do is divide by the cost per fez, which is 9.

135/9 = 15

Two angles are supplementary. The larger angle is three times the smaller

melomori [17]

9514 1404 393

Answer:

45°, 135°

Step-by-step explanation:

The total of the two angles is 1+3 = 4 times the smaller angle. The total is 180°, so the smaller angle is

180°/4 = 45°

The larger angle is 3×45° = 135°

The two angles are 45° and 135°.

Find the value of "k" such that 1/2 is a root of 2x^2+11x=-k

trapecia [35]

The value of k is -6

Step-by-step explanation:

The general form of the quadratic equation is y = ax² + bx + c

The roots of the equation is the values of x when y = 0
ax² + bx + c = 0, is used to find the roots

∵ 2x² + 11x = -k

- Add k to both sides

∴ 2x² + 11x + k = 0

∵ The roots of the quadratic equations is the values of x when y = 0

∵ $\frac{1}{2}$ is a root of the equation

- Substitute x by $\frac{1}{2}$ in the equation above to find k

∵ 2( $\frac{1}{2}$ )² + 11( $\frac{1}{2}$ ) + k = 0

∴ 2( $\frac{1}{4}$ ) + $\frac{11}{2}$ + k = 0

∴ $\frac{1}{2}$ + $\frac{11}{2}$ + k = 0

- Add the like terms

∵ $\frac{1}{2}$ + $\frac{11}{2}$ = $\frac{12}{2}$ = 6

∴ 6 + k = 0

- Subtract 6 from both sides

∴ k = -6

The value of k is -6
