Answer: A: 3 square feet per minute
Step-by-step explanation:
Answer:
300
Step-by-step explanation:
Evaluate 2 y^2 (y + x) where x = 1 and y = 5:
2 y^2 (y + x) = 2×5^2 (1 + 5)
Hint: | Evaluate 1 + 5.
1 + 5 = 6:
2×5^2×6
Hint: | Evaluate 5^2.
5^2 = 25:
2×25×6
Hint: | Multiply 2 and 25 together.
2×25 = 50:
50×6
Hint: | Multiply 50 and 6 together.
50×6 = 300:
Answer: 300
Answer:
ty
Step-by-step explanation:
We are interested in the left-end area under the standard normal curve that has the area 0.025.
But the problem seems to be simpler than that:
If n = number of students in the class, and we know that 2.5% of these students failed the course, and that 5 failed, then we can surmise that
0.025n = 5. Solving for n by multiplying both sides by 40, we get n = 200.
There were 200 students in the class.
It is perfectly fair for a teacher to put more info into a problem statement than you really need to solve the problem. That seems to be what happened here.
