Answer: v = B/y -1
B = yv + y = (v + 1)y
=> B/y = v + 1
⇔ [tex]v=\frac{B}{y}-1[/tex]

Answer:
89.1 liters
Step-by-step explanation:
"At the same rate" means miles and liters are proportional. The unknown is liters, so we can write the proportion with liters in the numerator:
liters/miles = x/672 = 49/369.6
Multiplying by 672, we have ...
x = 672(49/369.6) ≈ 89.09091
It will take 89.1 liters of gas to go 672 miles.
The quotient of a number and 4 is less than -1
Write the word sentence as an inequality
Less than = <
Quotient= Division
4 divided by X(unknown) will be LESS than -1
Answer---> X divided by 4 < -1

In triangle ABC, angle A is 35 and angle b is 20 select all triangle which are similar to triangle ABC.
Answer:
The similar one are 1 and 5
A. Triangle DEF where ∠D is 35° and ∠E is 20°.
C. Triangle JKL where ∠J is 35° and ∠L is 125°.
D. Triangle MNO where ∠N is 20° and ∠O is 125°.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know the sum of all the interior angles of a triangle is equal to 180°.
Given, A triangle ABC has ∠A = 35° and ∠B = 20°.
∴ ∠C = 180° - 35° - 20°.
∠C = 125°.
Triangle will be similar if every corresponding angle of different triangles has the same measure.
So, Triangles that are similar to triangle ABC is triangle DEF where ∠D is 35° and ∠E is 20°.
Triangle JKL where ∠J is 35° and ∠L is 125°.
Triangle MNO where ∠N is 20° and ∠O is 125°.

The Venn diagram represents enrollment in various classes at a certain high school. 12 students take math (Math) only. 11 students take English (Eng) only. 16 students take biology (Bio) only. 30 students are enrolled in math and English, but not biology. 15 students are enrolled in all three classes. 200 students attend the school, and 16 students take biology and English, but not math. How many students are enrolled in math and biology, but not English?
A.
12
B.
17
C.
75
D.
100
Please select the best answer from the choices provided
A
B
C
D
Using the symbols in the Venn diagram, we want to find A given that
B = 16
C = 15
D = 30
and given that 25 students don't take any of these courses.
There are 200 students total, so we need to have A plus the total number of students given in the diagram sum to 200. This means
(math only) + (English only) + (biology only) + (math and English, no biology) + (math and biology, no English) + (English and biology, no math) + (all three) + (none of the three) = 200
or
12 + 11 + 16 + 30 + A + 16 + 15 + 25 = 200
Solve for A to get A = 75, making the answer C.

Answer:
x = 11
y = 8
z = 42
Step-by-step explanation:
From the given figure
∵ l[tex]_{1}[/tex] and l[tex]_{2}[/tex] intersected at a point
∴ ∠1 and ∠4 are vertically opposite angles
→ Vertically opposite angles are equal in measures
∴ m∠1 = m∠4
∵ m∠1 = 4(3y - 12)°
∵ m∠4 = (8y - 16)°
→ Equate their measures
∵ 4(3y - 12) = 8y - 16
∴ 4(3y) - 4(12) = 8y - 16
∴ 12y - 48 = 8y - 16
→ Subtract 8y from both sides
∵ 12y - 8y - 48 = 8y - 8y - 16
∴ 4y - 48 = -16
→ Add 48 to both sides
∴ 4y - 48 + 48 = -16 + 48
∴ 4y = 32
→ Divide both sides by 4
∴ y = 8
∵ ∠4 and ∠5 formed a pair of linear angles
→ The sum of the measures of the linear angles is 180°
∴ m∠4 + m∠5 = 180°
∵ m∠5 = (12x)°
∵ m∠4 = 8(8) - 16 = 64 - 16 = 48°
→ Add them and equate the sum by 180
∵ 48 + 12x = 180
→ Subtract 48 from both sides
∴ 48 - 48 + 12x = 180 - 48
∴ 12x = 132
→ Divide both sides by 12
∴ x = 11
∵ ∠4, ∠3, and ∠2 formed a line
∴ ∠4, ∠3, and ∠2 are linear angles
→ The sum of the measure of the linear angles is 180°
∴ m∠4 + m∠3 + m∠2 = 180°
∵ m∠4 = 48°
∵ m∠3 = 3(11) + 9 = 33 + 9 = 42°
∵ m∠2 = (2z + 6)
→ Add them and equate the sum by 180
∵ 48 + 42 + 2z + 6 = 180
→ Add the like terms in the left side
∴ 96 + 2z = 180
→ Subtract 96 from both sides
∵ 96 - 96 + 2z = 180 - 96
∴ 2z = 84
→ Divide both sides by 2
∴ z = 42

For a group of 70 people, assuming that each person is equally likely to have a birthday on each of 365 days in the year, compute (a) The expected number of days of the year that are birthdays of exactly 4 people:
Answer:
0.0157
Step-by-step explanation:
From the information given:
The sample size = 70
The expected no. of days of year that are birthday of exactly 4 people is:[tex]P = \bigg [ \dfrac{1}{365} \bigg]^4[/tex]
The expected number of days with 4 birthdays = [tex]\sum \limits ^{365}_{i=1} E(x_i)[/tex]
[tex]\sum \limits ^{365}_{i=1} E(x_i) = 365 \times \bigg[ \ ^{70}C_{4} \times ( \dfrac{1}{365})^4 ( 1 - \dfrac{1}{365})^{70-4} \bigg][/tex]
[tex]\sum \limits ^{365}_{i=1} E(x_i) = 365 \times \bigg[ \ \dfrac{70!}{4!(70-4)!} \times ( \dfrac{1}{365})^4 ( 1 - \dfrac{1}{365})^{66} \bigg][/tex]
[tex]\sum \limits ^{365}_{i=1} E(x_i) = 365 \times \bigg[ \ 916895 \times 5.6342 \times 10^{-11} \times 0.8343768898 \bigg][/tex]
= 0.0157
Therefore, the required probability = 0.0157

Define confidence interval and degree of confidence. Provide at least one example of a confidence interval and interpret the result.
Answer:
confidence interval:
This tells us the degree of certainty or uncertainty that is existent in a sampling method. It gives us a range of values, telling us we are fairly sure that our true value or parameter lies within the range.
Degree of confidence:
This tells us that the confidence interval has captured the true/exact population parameter.
If we have 95% degree of confidence, we are 95% sure that that the exact/true parameter are in the confidence interval
