Coach Kasongo wants to know how many of his swimmers have times in each of four time ranges. He times each swimmer and records the data so he can compare their speeds. Would a dot plot or a histogram be a more appropriate way to display the data for this situation? A. A dot plot, because Coach Kasongo wants to show how the data fall into different intervals or ranges. B. A histogram, because Coach Kasongo wants to show how the data fall into different intervals or ranges. C. A dot plot, because Coach Kasongo wants to show all of the individual data values D. A histogram, because Coach Kasongo wants to show all of the individual data values.
Answer: D
Step-by-step explanation:
Answer:

What is the solution to the system of linear equations below? 2/5x−y=6 −2x+5y=−30 Select one: A. (-13, 14) B. (-5, -8) C. no solution D. infinitely many solutions
Answer:
D. Infinitely many solutions
Step-by-step explanation:
[tex]-\frac{2}{5}x-y=6 | -2x+5y=-30[/tex]
1.Since neither equation contains an isolated. However, we can isolate -y in the first equation by adding [tex]\frac{2}{5}x[/tex] to both sides.
Like this: [tex]\frac{2}{5}x-\frac{2}{5}x-y=6-\frac{2}{5}x[/tex]
ending up with [tex]y=6-\frac{2}{5}x[/tex]
2.Now, we can change y to a positive y. By doing so, we divide -y by the entire equation.
Like this [tex]\frac{-y=6-\frac{2}{5}x }{-y}[/tex]
Ending with [tex]y=-6+\frac{2}{5}x[/tex]
3.Now, we can plug the expression [tex]-6+\frac{2}{5}x[/tex] into the second equation as a substitute for y, and solve for x. Then, we can use x to calculate y.
Like this [tex]-2x+5(-6+\frac{2}{5}x)=-30\\ -2x-30+2x=-30\\[/tex]
4. Since -2x+2x would cancel out and leave -30=-30. This is true because we know -30 equals -30 with no variable in sight.

Please help me find the perimeter and area of this parallelogram.
Answer:
60 in
Step-by-step explanation:
15 x 4= 60
Answer:
Hello,
Area -
You have to times the height and the width
Width is top and Height is the side
Take 15 x 6 = 90 cm
Perimeter -
(This parts a little hard for me)
Then I think you have to do...
The perimeter of a parallelogram is the distance around the outside of the parallelogram
A parallelogram has four sides with opposite sides being congruent.
The formula for finding the perimeter is Side A + Side B + Side A + Side B.
(But here's a tip the side are the same because they are the same height)

Write the equation of the line in slope-intercept form using y=mx+b
Answer:
y= -100 x= 100
Step-by-step explanation: The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a. The form y=m(x-a) is essentially different from the other two forms, and means slope m and x-intercept (instead of y-intercept) a.

Answer:
1. 4.5x - 151.89
2. -2x + 375
Step-by-step explanation:
1.
Start with -$126.89
Small deposit: x (add)
Large deposit: 3.5x (add)
Withdrawal: $25 (subtract)
-126.89 + x + 3.5x - 25 =
= -151.89 + 4.5x
= 4.5x - 151.89
Answer: 4.5x - 151.89
2.
Start with $350
Small withdrawal: x (subtract)
Large withdrawal: x + 50 (subtract)
Deposit: $75 (add)
350 - x - (x + 50) + 75 =
= 350 - x - x - 50 + 75
= -2x + 375
Answer: -2x + 375

Write and solve the equation that represents the sentence below.
The product of 18 and a number is 109.8.
Which statements are correct? Check all that apply.
It can be solved by using the division property of equality.
It can be solved by using the multiplication property of equality.
The equation should be StartFraction x Over 18 EndFraction = 109.8.
The equation should be 18 x = 109.8.
The answer is 6.1.
The answer is 1,976.4.
Answer:
The equation should be 18x = 109.8
The answer is 6.1
