Answer:
it will be y=3x +? i forgot how to find b
Step-by-step explanation:
Answer:
-0.85 > -0.98
or
-0.85 is greater than -0.98
Step-by-step explanation:
when comparing two number . . . you usually look first at the ones places, then if they are equal, then you look at the tens place, then then farther back untill one number is larger than the other.
However with negive numbers, you are looking to see the smaller number (closer to zero)
so -0.85 is (smaller in a sense) but is less negetive
-0.98 is farther from zero
hope this helped. please mark me brainliest!
Answer:
y - y1 = m(x - x1)
y - -3 = 3(x - 1)
y + 3 = 3x - 3
y = 3x - 3 - 3
y = 3x - 6
y = 3x - 6
Step-by-step explanation:
Thie equation is in slope-intercept form (y = mx + b)
The y-intercept is -6 .... ((0, -6) is one point on the line.
It is given that (1, -3) is also on the line. So to graph, plot those
2 points and connect them with a line.
Set this up as a ratio putting inches on top and feet on bottom. Then your first ratio would be 1/25 since 1 inch is the same as 25 feet. In between them goes an equals sign and the the other ratio has an x on top (because inches is what we are looking for) and the 1500 on the bottom. Cross multiply to solve for x:
1(1500) = x(25). Divide both sides by 25 to get 60
Answer:
a) 320 students
b) 25 students
Step-by-step explanation:
Number of 18-years old in the survey:
(We add all frequency points for each line)
0 + 30 + 20 + 60 + 70 + 40 + 60 + 40 + 0 = 320 students
Number of 18 year old spending between 25 and 35 minutes: 40 + 65 = 105
Number of 12 year old spending between 25 and 35 minutes: 30 + 50 = 80
105 - 80 = 25 students
