Answer:
Bob Saves 168$.
Step-by-step explanation:
According to the Question,
- Given That, Amy , bob and hadi saved $1012 altogether.
Thus, A + B + H = 1012 ⇒ Amy saved $85.
So, B + H = 927 ----- Equation 1
- And Hadi saved 3 times as much as the total amount of Amy's and Bob's savings So, H = 3(A + B) ⇒ We Know Amy saved $85.
So, H - 3B = 255 ----- Equation 2
- Now, Subtract Equation 2 from Equation 1, We get
4B = 672 ⇒ B = 168
Bob Saves 168$.
The probability of getting exact two tails is 1/4
We need to find 19% of 205.
To compute any percentage, you divide by 100 and then multiply by the percentage you want:
So, there are 39 students in fifth grade (we obvisouly had to round, since there can't be a fractional number of students)
