Answer:
her salary after 8 years is $26,602
Step-by-step explanation:
Given that
Fiona salary is $21,000
She received 3% raise each year
We need to find her salary after 8 years
So, here we apply the future value formula
i.e.
= Present value × (1 + rate of interest)^number of years
= $21,000 × (1 + 0.03)^8
= $21,000 × 1.03^8
= $26,602
hence, her salary after 8 years is $26,602
You want to try and get rid of one of the variables ( x or y) so you would multiply the second equation by 2 which would make the x variable -2x which then when added to the first equation would eliminate the x variable.
Answer: c. Multiply the second equation by 2.
10/8 can be simplified to 5/4, which is the same as 1.25 (divide numerator 5 by denominator 4).
So you have x>1.25.
All numbers greater than 1.25 are possible solutions.
12 feet + 16 feet= 28 feet needed
The store does not have enough fabric.
There are 3 feet in a yard.
8 yards * 3 feet= 24 feet of fabric available
Answer:
0.35
Step-by-step explanation:
This probability distribution is shown below:
Pitch 1 2 3 4 5
Frequency 15 20 40 15 10
Probability 0.15 0.2 0.4 0.15 0.1
The probability that the pitcher will throw fewer than 3 pitches to a batter = P(X < 3)
X is the number of pitches thrown. Therefore:
P(X < 3) = P(X = 1) or P(X = 2)
The additive rule pf probability states that if two events X and Y are dependent events, the probability of X or Y occurring is the sum of their individual probability.
P(X < 3) = P(X = 1) or P(X = 2) = P(X = 1) + P(X = 2) = 0.15 + 0.2 = 0.35
The probability that the pitcher will throw fewer than 3 pitches to a batter = 0.35
