Answer:
20
Step-by-step explanation:
If she has 5 yards and she cuts them into 1/4 each. You're basically multiplying 5 by 4, and that's 20.
To get the required value of the missing probability to
make the series complete is to deduct all the probability given to 1 because we
know that the discrete probability distribution must be equal to 1. So doing
what I have said, this will be:
P(4) = 1 - P(3) - P(5) - P(6)
= 1 – 0.3 – 0.18 – 0.21

Answer:
y=3x
Step-by-step explanation:
You could find the need of pine board by finding the perimeter of the frame. But first you need to equalize the units, because one of them is in feet and the other one is in inches.
18 inches = 18/12 feet
18 inches = 1.5 feet
perimeter = l + w + l + w
perimeter = 2 + 1.5 + 2 + 1.5
perimeter = 7
The perimeter is equal to 7 feet, therefore Carl needs 7 feet of pine board
The quickest way to tell if a line is perpendicular is to find the slope, so you'll need to get the slope for both lines
PQ = ((-8) - (-9))/(2 - 0) = 1/2
and, for reference, a perpendicular slope is the negative reciprocal of the original (so we're looking for -2)
RS = (3 - 4)/(3 - 1) = -1/2
so, no, these two lines aren't perpendicular because the slope of RS is only the negative of PQ, not the negative <em>reciprocal</em>.
