Answer:
Probability that a car need to be repaired once = 20% = 0.20
Probability that a car need to be repaired twice = 8% = 0.08
Probability that a car need to be repaired three or more = 2% = 0.02
a) If you own two cars what is the probability that neither will need repair?
Probability that a car need to be repaired once , twice and thrice or more= 0.20+0.08+0.02=0.3
Probability that car need no repair = 1-0.3=0.7
Neither car will need repair=
b) both will need repair?
Probability both will need repair =
c)at least one car will need repair
Neither car will need repair=
Probability that at least one car will need repair= 1-0.49 = 0.51
Answer:
y= -2/3x+3
Step-by-step explanation:
Parallel lines have the same slope but different y-intercepts.
y=-2/3x is your original equation
Your slope is still -2/3
y=mx+b
y=-2/3x + b
Substitute the points from the coordinates
5 = -2/3(-3) + b
5 = 2 + b
-2 -2
b=3
Your parallel line equation is: y= -2/3x+3
Have a great day!
Answer:
+1
Step-by-step explanation:
For getting to the answer of this question, one has to know the conversion between kilometer and miles as well as the conversion between gallons and liter.
1 mile = 1.609 km
Then
16 km = 16/1.609 miles
= 9.94 miles
Again
3.785 liter = 1 gallon
then
1 liter = 1/3.784 gallons
= 0.26 liter
So
16 km/L = (9.94/0.26) miles per gallon
= 38.23 miles per gallon.
= 38 gallons
94-30=60
30 because there are four sides to a rectangle and two of them are 15 feet (wide) so 15+15=30
