What multiplys to 40 and adds to -13

Answers

-5 and -8 both multiply to 40 -5 x -8 = 40 and both add up to -13. -5 + -8 = -13. two negative numbers when added together the answer is still negative. ex: if i owe 2 dollars to someone and 2 to another i owe 4 in total
We know that both of our numbers will need to be negative so that they multiply to get a positive number (the double negatives cancel) but add to get a negative one.
Consider factor pairs of 40.

-40 × -1 = 40 (adds to -41)
-20 × -2 = 40 (adds to -22)
-10 × -4 = 40 (adds to -14)
-5 × 8 = 40 (adds to -13)

Your numbers are -5 and -8.

The histogram shows the duration, in minutes, of movies in theaters. What relationship between the median and mean is shown by the histogram?

The mean is less than the median.
The median is less than the mean.
The mean is equal to the median.
The median and mean cannot be compared from a histogram.

Answers

The correct answer is:

The median is less than the mean.

Explanation:

This histogram is skewed right; the data "peaks" further to the left than the center.

If a histogram is skewed right, the mean is greater than the median.

This is because skewed-right data have a few large values that increase the mean but do not affect where the exact middle of the data is.

Answer:

Option B) The median is less than the mean.

Step-by-step explanation:

We are given the following in the question:

A histogram showing the duration, in minutes, of movies in theaters.

  • If we observe the shape of the histogram, more values of the histogram lies on the right side, the tail of the distribution is longer on the right hand side than on the left hand side
  • Hence, the histogram is skewed right.
  • The histogram is not normal and shows skewness.
  • It is a right skewed histogram or positively skewed.
  • Now, for a positively skewed data the mean is greater than the median since more values lies on right side and have a greater value thus the mean increases.
  • \text{Mean} > \text{Median}
  • The relationship shown by the histogram between mean and median is that median is less than the mean

Jesse earns $12.62 an hour, plus she earns overtime for hours exceeding 40 hours per week. What is her gross weekly pay for working 47 hours if she gets time and a half for overtime?A) $541.73
B) $600.14
C) $637.31
D) $849.71

**NOTE: My answer choice is d

Answers

the correct answer is c) $637.31

12.62 x 40 = 504.8

time and a half is the amount you get paid + half the amount you get paid 

so half of 12.62 is 6.31 + 12.62 = 18.93

18.93 x 7 = 132.51

504.8 + 132.51 = 637.31

A dartboard has a diameter of 18 inches.What are its radius and circumference?

Answers

Diameter of the dartboard as given in the question = 18 inches
Then
Radius of the dartboard will be = 18/2 inches
                                                  = 9 inches
We already know that
Circumference of a circle = r
We also know that the value of π = 3.14159
Then
Circumference of the dartboard = 2 * 3.14159 * 9 inches
                                                    = 56.548 inches
                                                    = 56.55 inches
So the radius of the dartboard is 9 inches and the circumference of the dartboard is 56.55 inches. I hope the procedure is absolutely clear to you.

What is the line symmetry for the graph of y= -3x^2+12x-11

Answers

Answer:

The line of symmetry is x=2

Step-by-step explanation:

Given:y=-3x^2+12x-11

We are given a quadratic equation and to find the line of symmetry.

As we know the line of symmetry of parabola passes through the x value of vertex.

If vertex of parabola is (h,k) then equation of line of symmetry x=h

So, first we find the vertex of parabola.

For equation: y=ax^2+bx+c

x=-(b)/(2a)

For given equation, a=-3 and b=12

Therefore, x=-(12)/(2(-3))

x=2

Hence, The line of symmetry of given parabola is x=2

The answer to your question is x=2. what you want to do is find both the x values for your quadratic equation and then add them and divide by 2.
