Answer:
35 in^2
Step-by-step explanation:
The area of a trapezoid is the average of the bases times the height.
Base 1: 8, Base 2: 6, Height: 5
(8 + 6)/2 = 7
7 * 5 = 35 in^2

. Suppose that 10 students of a class of 50 undergraduates are chosen for a behavioral experiment. The total class consists of 15 freshmen, 18 sophomores, 10 juniors, and 7 seniors. If all students are equally likely to be picked, determine the probability of the group contains exactly seven seniors and three juniors.
Answer:
Approximately 0% probability of the group contains exactly seven seniors and three juniors.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, the order in which the students are chosen is not important, which means that we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Desired outcomes:
7 seniors, from a set of 7.
3 juniors, from a set of 10. So
[tex]D = C_{7,7} \times C_{10,3} = \frac{7!}{7!(7-7)!} \times \frac{10!}{3!(10-3)&} = 1 \times 120 = 120[/tex]
Total outcomes:
10 students froms a set of 50. so
[tex]T = C_{50,10} = \frac{50!}{10!(50-10)!} = 10272278170[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{120}{10272278170} \approx 0[/tex]
Approximately 0% probability of the group contains exactly seven seniors and three juniors.

A triangle has a base of 4x+2 and a height of x+4. Find the area.
Answer:
15 height
Step-by-step explanation:
Answer:
2x^2 + 9x + 4
Step-by-step explanation:
To find the area of a triangle, use the formula, 1/2 · base · height = area.
If we plug the given expressions into the formula, we get
1/2(4x+2)(x+4)
Which simplifies to
(2x+1)(x+4)
=2x^2 + 9x + 4

what is 452÷6 in long division
Answer: 75.333333...
Step-by-step explanation: Might want to round that number to the nearest tenths. This number is a repeating digit.
Here we will show you step-by-step with detailed explanation how to calculate 452 divided by 6 using long division.
Before you continue, note that in the problem 452 divided by 6, the numbers are defined as follows:
452 = dividend
6 = divisor
Step 1:
Start by setting it up with the divisor 6 on the left side and the dividend 452 on the right side like this:
6 ⟌ 4 5 2
Step 2:
The divisor (6) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:
0
6 ⟌ 4 5 2
Step 3:
Multiply the divisor by the result in the previous step (6 x 0 = 0) and write that answer below the dividend.
0
6 ⟌ 4 5 2
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.
0
6 ⟌ 4 5 2
- 0
4
Step 5:
Move down the 2nd digit of the dividend (5) like this:
0
6 ⟌ 4 5 2
- 0
4 5
Step 6:
The divisor (6) goes into the bottom number (45), 7 time(s). Therefore, put 7 on top:
0 7
6 ⟌ 4 5 2
- 0
4 5
Step 7:
Multiply the divisor by the result in the previous step (6 x 7 = 42) and write that answer at the bottom:
0 7
6 ⟌ 4 5 2
- 0
4 5
4 2
Step 8:
Subtract the result in the previous step from the number written above it. (45 - 42 = 3) and write the answer at the bottom.
0 7
6 ⟌ 4 5 2
- 0
4 5
- 4 2
3
Step 9:
Move down the last digit of the dividend (2) like this:
0 7
6 ⟌ 4 5 2
- 0
4 5
- 4 2
3 2
Step 10:
The divisor (6) goes into the bottom number (32), 5 time(s). Therefore put 5 on top:
0 7 5
6 ⟌ 4 5 2
- 0
4 5
- 4 2
3 2
Step 11:
Multiply the divisor by the result in the previous step (6 x 5 = 30) and write the answer at the bottom:
0 7 5
6 ⟌ 4 5 2
- 0
4 5
- 4 2
3 2
3 0
Step 12:
Subtract the result in the previous step from the number written above it. (32 - 30 = 2) and write the answer at the bottom.
0 7 5
6 ⟌ 4 5 2
- 0
4 5
- 4 2
3 2
- 3 0
2
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 452 divided by 6 calculated using Long Division is:

a rectangle has perimeter 86 cm and length 37 cm. what is its width
Answer:
6 cm
Step-by-step explanation:
37 × 2 = 74 cm86 - 74 = 12 cm12 ÷ 2 = 6 cmSo, the width is 6 cmI hope this helps!
Answer:
The rectangle's width is 6.
Step-by-step explanation:
You are given the perimeter is 86 cm. The perimeter is the sum of all the sums. For a rectangle, use the formula, P = 2l + 2w. So, we plug the given into our equation: P = 86, l = 37. This results in:
86 = 2(37) + 2w
86 = 74 + 2w
Subtract 74 on each side.
2w = 12
Then, divide each side by 2.
w = 6
Hopefully this helped. And good luck in your studies.

Answer:
[tex]V=343\,\,cm^3[/tex]
Step-by-step explanation:
Recall that fractional exponents are other form of representing roots.
In our case, the formula for the volume of the cube in terms of area of a face, is also written as:
[tex]V=A^\frac{3}{2} =(\sqrt{A} )^3[/tex]
which for the case of a cube with face area of 49 cm^2 becomes:
[tex]V=(\sqrt{49} )^3=7^3=343\,\,cm^3[/tex]
A state began an effort to increase the deer population. In year 2 of the effort, the deer population in a state forest was 1,200. In year 4, the population was 1,728.
The explicit rule for the geometric sequence is:
Answer:
nth term = 1000×1.2ⁿ⁻¹
Step-by-step explanation:
The explicit rule for the given geometric sequence is aₙ = a₁rⁿ⁻¹ = 1000 x 1.2ⁿ⁻¹
What is a geometric sequence?A geometric sequence is a special type of sequence where the ratio of every two successive terms is a constant.
Given that, in two years the deer population in a state forest was 1,200. In year 4, the population was 1,728,
Therefore,
a₄ = 1728 and a₂ = 1200
We have two terms of the GP, therefore, finding r,
r² = 1728 / 1200 = 1.44
r = 1.2
Therefore,
a₁ = a₂r¹⁻²
= 1200r⁻¹ = 1200/r
= 1200 / 1.2 = 1000
Therefore, the formula will be = aₙ = a₁rⁿ⁻¹ = 1000 x 1.2ⁿ⁻¹
Hence, the explicit rule for the given geometric sequence is aₙ = a₁rⁿ⁻¹ = 1000 x 1.2ⁿ⁻¹

Sn = (2·a1 +d(n -1))(n/2)
This series has first term a1=5 and common difference d=7. Then the total distance traveled in 30 seconds is ...
S30 = (2·5 +7(30-1))(30/2) = (10 +203)(15) = 3195
