Answer:
18.4%
Step-by-step explanation:
The formula for rel. freq. is:
Relative Frequency = Class Frequency/n
Where
Class Frequency will be the number of students in the class we are interested in (in 35-38, the number of students is 9)
n is the total number of students [which is 6+7+8+9+10+9= 49]
Putting into formula we get:
Relative Frequency = 9/49 = 0.1837
To get percentage, we need to multiply by 100:
0.1837 * 100 = 18.37%
Rounded to 1 decimal place, that is 18.4%
Answer: C) three times a number minus two is more than 16
Explanation: < represents greater than
Answer: 72yd^2
Step-by-step explanation:
Answer:
y = 2x + 1
Step-by-step explanation:
Find the slope
( -2 , -3) ( 2 , 5)
m = (y2 - y1 )/(x2 - x1)
x1= -2
y1 = -3
x2 = 2
y2 = 5
m = 5 - (-3)/ ( 2 - (-2)
m = (5 + 3) / ( 2 + 2)
= 8/4
= 2
m = 2
Using the equation of a line
y = mx + c
y - intercept point y
m - slope of the line
x - intercept point x
c - intercept
Substitute m into the equation
y = 2x + c
Substitute any of the two points given into the equation
( 2 ,5 )
x - 2
y - 5
y = 2x + c
5 = 2(2) + c.
5 = 4 + c
c = 5 - 4
c = 1
The equation of the line
y = 2x + 1
