26 ft 11 1/4 inches minus 26 ft 8 1/16 inch
26-26 = 0
so you need to subtract the inches
so you have 11 1/4 = 8 1/16
11-8 = 3 inches
1/4 = 1/16 - find common denominator ( 16)
1/4 = 4/16, 4/16-1/16 = 3/16
the jump was 3 3/16 inches longer
Answer:
13.5
Step-by-step explanation:
When you convert fraction numbers to decimal numbers, remember they are written like this:
whole . parts
In 13 1/2, you have 13 wholes and 1/2 parts. The decimal number would look like 13 . parts
To find the decimal for 1/2, put into your calculator <u>1 ÷ 2</u>. The answer will be 0.5 Write "5" for parts. The decimal where 0.5 is will line up with the decimal in the decimal number.

Answer:
a+2b
Step-by-step explanation:
2(a+2b)-a-2b
2a+4b-a-2b
=a+2b
Answer: a. 0.61
b. 0.37
c. 0.63
Step-by-step explanation:
From the question,
P(A) = 0.39 and P(B) = 0.24
P(success) + P( failure) = 1
A) What is the probability that the component does not fail the test?
Since A is the event that the component fails a particular test, the probability that the component does not fail the test will be P(success). This will be:
= 1 - P(A)
= 1 - 0.39
= 0.61
B) What is the probability that a component works perfectly well (i.e., neither displays strain nor fails the test)?
This will be the probability that the component does not fail the test minus the event that the component displays strain but does not actually fail. This will be:
= [1 - P(A)] - P(B)
= 0.61 - 0.24
= 0.37
C) What is the probability that the component either fails or shows strain in the test?
This will simply be:
= 1 - P(probability that a component works perfectly well)
= 1 - 0.37
= 0.63
