Answer:
The slope should be -5/8
Step-by-step explanation:
The equation used to find the slope using a table is:
![\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
To get the values, take two points from the table. For example:
(8, -5) and (16, -10)
Write and classify them as (x1, y1) and (x2, y2). Knowing that these values equal the numbers, put the numbers in the equation above, and you should find the slope.
Answer:
The cumulative frequency distribution that corresponds to the given frequency distribution is shown in the explanation part as well as in the attachment.
Step-by-step explanation:
A cumulative frequency distribution is the sum of the class and all classes below it in a frequency distribution.
The cumulative frequency distribution that corresponds to the given frequency distribution speed number of cars is shown below and better shown in the attachment below.
Speed Number of cars Cumulative frequency
0 - 29 4 4
30 - 59 16 20
60 - 89 60 80
90 - 119 20 100
Then you plug the rest into point-slope form (you can use either of the points, I used the first one)
y - y1 = m(x - x1)
Remember that m is the slope.
y + 2 = 2(x + 8)
Distribute the slope to the parenthesis
y + 2 = 2x + 16
Isolate the y variable
y = 2x + 14
Answer:
175 degrees Fahrenheit
Step-by-step explanation:
We are to find the difference between the two temperatures
125 - (-50)
two minuses gives a plus
125 = 50 = 175
