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°.

It has a fixed cost of $62,150. If the selling price per unit is $9.50 and the variable cost per unit is $6.25, the breakeven point is
Answer:
Break-even point = $19,123 (Approx)
Step-by-step explanation:
Given:
Fixed cost = $62,150
Selling price = $9.50
Variable cost = $6.25
Find:
Break-even point
Computation:
Break-even point = Fixed cost / [Selling price - Variable cost]
Break-even point = 62150/[9.50-6.25]
Break-even point = 62150/3.25
Break-even point = $19,123 (Approx)

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.

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
A booth at the farmer’s market has fresh goat cheese in three sizes of containers. The big container is 30 ounces and costs $9.00. The medium container is 15 ounces and costs $4.95. The small container is 8 ounces and costs $2.00. What size is the best buy? Justify your reasoning.
Answer:
8 ounce
Step-by-step explanation:
The 30 ounce container costs $0.30 per ounce. The 15 ounce container is $0.33 per ounce. The 8 ounce container is $0.25 per ounce. Therefore, the 8 ounce container costs less per each ounce.
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

Using the given formula, Pythagorean Triple with x = 8 and y = 3 is 5329=5329.
What are Pythagorean triples?Pythagorean triples are a²+b² =c² where a, b and c are the three positive integers. These triples are represented as (a,b,c). Here, a is the perpendicular, b is the base and c is the hypotenuse of the right-angled triangle.
Given that, x=8 and y=3.
The formula is (x²+ y²)²= (x² - y²)² + (2xy)²
Now, (8²+ 3²)²= (8² - 3²)² + (2×8×3)²
(64+9)²=(64-9)² +(48)²
73²=55²+48²

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]
