If triangle MNO and triangle PQR are similar, which of the following must be true?
Answer:
C and D
Step-by-step explanation:
Want explanation? Comment
Answer:
D
Step-by-step explanation:
It looks like triangle MNO and PQR are similar because PQR is a smaller version of MNO reversed. If this is true, MN is equal to PQ, OM is equal to RP, and ON is equal to RQ. Therefore, the answer should be D.

In a class of 25 students, 16 have a brother and 10 have a sister. There are 6 students who have a brother and a sister. What is the probability that a student chosen randomly from the class has a sister?
The probability that a student chosen randomly from the class has a sister, in a class of 25 students, is 2/5.
What is the addition rule of probability for two events?For two events A and B, we have:
Probability that event A or B occurs = Probability that event A occurs + Probability that event B occurs - Probability that both the event A and B occur simultaneously.
This can be written symbolically as:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
For three events, A, B and C:
[tex]P(A \cup B \cup C) = P(A) + P(B) + P(C) - P(A\cap B) - P(A \cap C) - P(B \cap C) + P(A \cap B \cap C)[/tex]
In a class of 25 students, 16 have a brother and 10 have a sister. There are 6 students who have a brother and a sister.
Let A is event of a student having a brother and B is event of a student having a sister.
The probability of event A is,
[tex]P(A)=\dfrac{16}{25}[/tex]
The probability of event B is,
[tex]P(B)=\dfrac{10}{25}\\P(B)=\dfrac{2}{5}[/tex]
The probability of occurrence of both event A and B together,
[tex]P(A\cap B)=\dfrac{6}{25}[/tex]
Thus, the probability that a student chosen randomly from the class has a sister, in a class of 25 students, is 2/5.

Step-by-step explanation:
Kat is interested in getting chickens so she can have fresh eggs. Before she buys her chickens, she wants to find the mean number of eggs each one will lay. She begins by randomly selecting 40 chickens from a large poultry farm and counts how many eggs each one lays within one month. She finds the mean to be 24.8 eggs with a standard deviation of 6.9 eggs. Which of the following is the 90% confidence interval for the true mean number of eggs chickens from this poultry farm lay in one month?
Find the t-table here.
(21.85, 27.75)
(22.59, 27.01)
(22.96, 26.64)
(23.38, 26.22)
Answer:
C
Step-by-step explanation:
Took it
The confidence interval of eggs chickens from this poultry farm lay in one month will be (22.96, 26.64). Then the correct option is C.
What is the confidence interval of the sample?If the sample size is given to be n < 30, then for finding the confidence interval for mean of population from this small sample, we use t-statistic.
Let the sample mean given as μ and
The sample standard deviation σ, and
The sample size = n, and
Then the heights would be outside the 90% confidence interval will be
For 90% confidence interval, we have z = 1.645
⇒ μ ± z (σ/√n)

8. If v2 = u2+2gs, find the value of s when v = 25,
u= 12 and g = 10.
Answer:
s = 24.05
Step-by-step explanation:
Given
v² = u² + 2gs ← substitute v = 25, u = 12, g = 10
25² = 12² + (2 × 10 × s)
625 = 144 + 20s ( subtract 144 from both sides )
481 = 20s ( divide both sides by 20 )
24.05 = s

Step-by-step explanation:
Maya throws a rock
straight up from the edge
of a 192-foot cliff and into
the ocean. After two
seconds, the rock
reaches a maximum
height of 256 feet. Four
seconds later, the rock
enters the ocean
Write an equation to
model the scenario.
Answer:
Step-by-step explanation:
2.256 = 4x
So first Maya throws the rock from the 192-foot cliff into the ocean.
After 2 seconds, the rock reaches a maximum height of 256 feet;
so 2 seconds, 256 feet - 2.256After 4 seconds, the rock reaches the ocean.
so 4 seconds, it reaches the ocean but we don't know how many feet. ( x )-- 4 seconds, x feet.equation: 2 . 256 = 4 . xGood luck!
The required equation that represents the scenario is x = 64 * 2 + 256 * 4
Given that,
Maya throws a rock straight up from the edge of a 192-foot cliff and into the ocean. After two seconds, the rock reaches a maximum height of 256 feet. Four seconds later, the rock enters the ocean. To write an equation to model the scenario.
the equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
let the total distance covered by the rock vertically be x,
now,
Distance traveled by the rock vertical upward in 2 seconds = 2 * (256 - 192)
= 2 * 64
Distance traveled by the rock vertical downward in 4 seconds = 4 * 256
Total distance,
x = 2 * 64 + 4 * 256
Thus, the required equation that represents the scenario is x = 64 * 2 + 256 * 40.

1. 71.25 ft^2
2. $2764.80
3. 84 in^2
4. 6 inches
Step-by-step explanation:
1. Area of a triangle is base x height x 1/2
2. Multiply the area by the amount: A = 768 so 768 x 3.60 = total cost
3. Area of a trapezoid is (base x height) x height / 2
4. Area of triangle is base x height x 1/2 so if you multiply the area by 2 and divide by 18, you can find the base, which is 6

Step-by-step explanation:
Here, we want to find the value of x
To do this, we use one of the circle tangent relationships
we have this as:
8^2= 4(4 +x)
8^2 = 16 + 4x
64 = 16 + 4x
64-16 = 4x
4x = 48
x = 48/4
x = 12
