Answer: You are correct. The mode is between 90 and 100
This is because the tallest bar corresponds to this interval. The mode is the most frequent value.
It's one solution.
no matter how you solve it, it will equal j = 1.
Answer:
I think it is (x^2+9) x (x-1) x (x+1)
Step-by-step explanation:
(not sure if right but had a go)
Answer:
5 degrees
Step-by-step explanation:
Answer: y = -2x + 10
Step-by-step explanation:
Two lines are said to be perpendicular if the product of their slope = -1, that is , if
is the slope of the first line and
is the slope of the second line , if the two lines are perpendicular , then 
= -1
The equation of the line given :
y = 1/2x - 1
comparing with the equation of line in slope intercept form
y = mx + c , where m is the slope and c is the y - intercept , it implies that
= 1/2
Therefore :
= -2
To find the equation of the line with slope -2 and passes through the point ( 3 , 4 ) we will use the formula
= m (
)
y - 4 = -2 ( x - 3 )
y - 4 = -2x + 6
y = -2x + 6 + 4
y = -2x + 10
