0.4 x 100 = 4%
There you go, you're welcome ;)
Answer:
4 stations
Step-by-step explanation:
If we need to be at least 98% certain that an enemy plane flying over will be detected by at least one station, we must ensure that there is at most a 2% chance that no radar stations detect the plane.
The probability that a single radar station does not detect the plane is 0.35.
For n radar stations:

Rounding up to the next whole station, at least 4 stations are needed.
Part A
c - number of washed cars
Answer: 400 + 5c > 900
Part B
400 + 5c > 900 | - 400
400 + 5c - 400 > 900 - 400
5c > 500 | : 5
5c : 5 > 500 : 5
c > 100
Answer: 100 cars
Answer:
Step-by-step explanation:
Let x represent the distance that the truck was driven.
Buck rented a truck for $39.95 plus $0.32 per mile. This means that the total cost of driving x miles with the truck would be
39.95 + 0.32x
Before returning the truck, he Filled the tank with gasoline, which cost $9.85. This means that the total amount that he spent is
39.95 + 0.32x + 9.85
If the total cost was $70.23, it means that
39.95 + 0.32x + 9.85 = 70.23
49.8 + 0.32x = 70.23
0.32x = 70.23 - 49.8 = 20.43
x = 20.43/0.32 = 63.8
Approximately 64 miles
Answer:
The Slope of a line formula is given by
m=y2 - y1/ x2 - x1
Now Form a triangle using the straight line(It'd be best if you choose known Points on the graph)
Picking points (1, 2) and (2, 5) connect these points and you'll have a small triangle.
x1 y1 x2 y2
Substituting into the formula
m=5-2/2-1
m=3.
