Nine less means minus 9
four times a number equals 4x
and equals fifteen is this = 15
lets put all our knowledge together to make an equation:)
4x - 9 = 15
merry christmas:)
Yes, this can happen if the rectangles are the same dimensions, BUT NO if the dimensions are different.

Answer: x = 3
Step-by-step explanation: First subtract 2x from both sides to get:
3x + 6 = 15
Then subtract 6 on both sides
3x = 9
Now divide by 3 to isolate x to get...
x = 3
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
