Answer:
9.8%
Step-by-step explanation:
Given the following information

Total Number of Students =6+4+5+7+10+9=41
Number of Students aged 19-22 =4
Therefore:
The relative frequency for the class with a lower class limit of 19

the answer is 3 u only need to remove the - sign
Answer:
(x+1)(x+9)
Step-by-step explanation:
using ac method
so there are 2 x so each go in a ( ) then you have to do the box method and get 9 at the right corner at the end. then get your 2 like terms combined then boom you got your answer.
Answer:
(2, 3) lies on the line y = 5 - x.
Step-by-step explanation:
Were there only two possible answer choices?
We can determine whether or not a given point, such as (2, 3), is contained in a function such as y = x - 1, by substituting the given coordinates 2 and 3 for x and y respectively; is the resulting equation true or false?
Check out (2, 3) and y = x - 1: 3 = 2 - 1, or 3 = 1. False. (2, 3) does not lie on the line y = x - 1. Does (2, 3) lie on the line y = 5 - x? Is 3 = 5 - 2 true? Yes. So (2, 3) lies on the line y = 5 - x.
Check out (2, 3) and y = 7 - 2x. Is 3 = 7 - 2(1) true? No, it is not true.
Y = 3x + 1
Because,
slope intercept form is y=mx+b
Where y is the y values, m is slope, x is x values, and b is y-intercept
First, to find the slope use rise/run, so rise (from 10 to 13) is 3 and run is (from 3 to 4) is 1, 3/1=3
Next to find y-intercept plug in the slope and some x and y values,
10=3(3)+b
10=9+b
1=b
So then the equation is y=3x+1 you can check by plugging stuff in and also I graphed it so I’ll add a picture
This is my first time answering questions so if I got something wrong ask or something hope this helps :)
