Answer:
All work shown in image...
Step-by-step explanation:
First find the area of the blue notebook by using the formula A=bh
A= 20×30 = 600 cm squared
Now find the area of the stickers using the same formula.
A=bh
A= 2 × 2 = 4 cm squared
Since there are 7 stickers then 4×7 = 28 cm squared is the area of all of them added together. Now simply subtract the area of the stickers from the area of the notebook to find how much of the notebook is still showing.
600 - 28 = 572 cm squared
Answer:
A
Step-by-step explanation:
you do a/18=4/a, cross multiply
a^2=72
a=6 square root of 2
<span>You are given the waiting times between a subway departure schedule and the arrival of a passenger that are uniformly distributed between 0 and 6 minutes. You are asked to find the probability that a randomly selected passenger has a waiting time greater than 3.25 minutes.
Le us denote P as the probability that the randomly selected passenger has a waiting time greater than 3.25 minutes.
P = (length of the shaded region) x (height of the shaded region)
P = (6 - 3.25) * (0.167)
P = 2.75 * 0.167
P = 0.40915
P = 0.41</span><span />
