Answer:
The probability of choosing an A student is 58% (0.58 or 29/50)
Step-by-step explanation:
The fact that 23 students are boys and 27 are girls is irrelevant to the question so we can ignore that.
There are 50 students in all and out of these students 15 boys and 14 girls made an A.
We can first add 15+14 which equals 29. So 29 students out of 50 made in A on the exam.
29/50 equals 0.58 or 58%.
Answer:
44
Step-by-step explanation:
f(x) = -7x + 5x^2 + 10
f(-2) = -7(-2) + 5(-2)^2 + 10
= 14 + 20 + 10
= 44
You can't find a value of x since there is no equal sign. This is not an equation. It is just an expression, so you can't solve it for x.
