Answer:
a) 0.9999
b)0.0001
Step-by-step explanation:
Given that probability of failure is 0.0001
Then;
a) finding the probability that none of the "criticality 1" items would fail will be;
1-0.0001 =0.9999
b)To find the probability of an event occurring at least once it will be the complement of the probability of the event never occurring.
P(at least one)= 1- P(none)
=1-0.9999= 0.0001
Answer:
Unit rates are ratios that are used to compare different quantities
Step-by-step explanation:
It really depends on what kind of unit rate you're answering. So let's say that you go to the grocery store, and potatoes are $5.50 for 5. You would divide 5.50 by 5 to get the answer $1.10. Hope this helps!
A system of equations is good for a problem like this.
Let x be the number of student tickets sold
Let y be the number of adult tickets sold
x + y = 200
2x + 3y = 490
x = 200 - y
2(200 - y) + 3y = 490
400 - 2y + 3y = 490
400 + y = 490
y = 90
The number of adult tickets sold was 90.
x + 90 = 200 --> x = 110
2x + 3(90) = 490 --> 2x + 270 = 490 --> 2x = 220 --> x = 110
The number student tickets sold was 110.
Answer:
First Answer:
$15,060.
Second Answer:
9.96 miles.
Third Answer:
$3.27.
Step-by-step explanation:
First Question:
Cost of the rented car = 50 + 0.20 = $50.20
How much did Matt's family spend for the car:
1 mile = $50.20
300 miles = ?
300 × 50.20
= $15,060.
Second Question:
If Hayden spent $500 for her rented car, how many miles did she drive:
$50.20 = 1 mile
$500 = ?
500 ÷ 50.20 = 9.96 miles.
Third Question:
What is the cost per gallon of gas:
24 gallons = $78.48
1 gallon = ?
78.48 ÷ 24 = $3.27.
Answer:
$36.00
Step-by-step explanation:
The formula for simple interest is I = P x r x t where P is the principal amount, $600.00, r is the interest rate, 2% per year, or in decimal form, 2/100=0.02, and t is the time involved, 3....year(s) time periods. So t is 3....year time periods. To find the simple interest, we multiply 600 × 0.02 × 3 to get that the interest is $36.00 . Usually now, the interest is added onto the principal to figure some new amount after 3 year(s), or 600.00 + 36.00 = 636.00.
