Answer:
16.4
Step-by-step explanation:
To decrease a number by 45% of its value, you subtract the 45%. To get 45%, you multiply the number by 0.45.
So, if x is the original number, then the equation for this word problem would be x - 0.45x = 9.
To solve, we first subtract 0.45x from x, which is 0.55x. This means that 0.55x is equal to 9. To simplify, we can divide both sides by 0.55. 9/0.55 is 16.36363636..., etc. The nearest tenth would be 0.4, so your answer is 16.4
Answer:
17
Step-by-step explanation:
The two values are equal, so just solve for x using
2x+32=4x-2
Answer:
P( x = 2) = 0.4
Or 40%
Step-by-step explanation:
Given that wildcat has 0.5 probability of winning if they play nine times
Probability = possible outcomes ÷ required outcome
The required outcome = 9
Probability = 0.5
Let calculate the possible outcomes
Possible outcomes = 0.5 × 9 = 4.5 games
the probability that the Wildcats win two of the games will be
P( x = 2) = 2/4.5 = 0.44
Or 44%
A[n] = (a[n-1] +a[n+1])/2 = (3.9 +7.1)/2 = 11/2 = 5.5
