Answer:
Step-by-step explanation:
The volume of a cylinder is given by ...
V = Bh . . . . . where B is the base area and h is the height
The volume of a pyramid or cone is given by ...
V = (1/3)Bh . . . . . where B is the base area and h is the height
The area of a square of side length s is ...
A = s²
The area of a circle of radius r is ...
A = πr²
___
Using these formulas, the volumes of these objects are ...
cylinder: (9π in²)(10 in) = 90π in³
square pyramid: (1/3)(4 in)²(7 in) = 37 1/3 in³
cone: (1/3)(π(2.5 in)²)(6 in) = 12.5π in³ . . . . slightly larger than the pyramid
Answer:
12.5

Math Test 20 40 7
Science Test 15 35 5
Which percentage of students took the math test and received a grade of 90 or above?
16.39%
29.85%
57.14%
28.69%
Let event A = "math test" and event B = "Score: 90-100." Then find , where
To find the percentage of students who took the math test and received a grade of 90 or above, we need to calculate the conditional probability P(A ∩ B), which is the probability of event A ("math test") and event B ("Score: 90-100") happening simultaneously.
From the two-way frequency table:
The number of students who took the math test and received a grade of 90 or above is 20.
The total number of students who took the math test is 20 + 40 + 7 = 67.
Now, we can calculate the conditional probability:
P(A ∩ B) = (Number of students who took the math test and received a grade of 90 or above) / (Total number of students who took the math test) × 100%
P(A ∩ B) = 20 / 67 × 100% ≈ 29.85%
So, the percentage of students who took the math test and received a grade of 90 or above is approximately 29.85%.
What is the practical domain of the function?
All integers from 2 to 6, inclusive.
{27, 39, 51, 63, 75}
All real numbers.
All real numbers from 2 to 6, inclusive.
Let
x--------> the number of dozen of eggs
f(x)-------> the number of eggs
we know that
The domain of the function is the amount of dozens of eggs that Monica can buy
The domain is the interval------->
All integers from to , inclusive
The range is the interval------->
therefore
the answer is the option
All integers from to , inclusive
