Skylar needs to buy a pair of dress pants for $40, a shirt for $30, and a tie for $20. Skylar has three coupons. The first coupon gives him x percent off on a shirt. The second coupon gives him y percent off on the dress pants. The third coupon gives him z percent off on his total purchase. He cannot combine the coupon for the total purchase with the other two coupons. These expressions give both possibilities for the total cost of Skylar's purchase after the coupons are applied. The variables represent percentages as decimals. (1−x)30+(1−y)40+20 (1−z)(40+30+20) Skylar uses the dress pants coupon. Which part of the expression represents the percent that Skylar will pay for the dress pants?

X and Y are two mutually exclusive events. P(X)= 0.55 and P(X or Y)=0.7. Work out P(not Y) (2 marks)
To find the probability of not Y occurring when events X and Y are mutually exclusive, we subtract P(X) from P(X or Y) to get P(Y) and then subtract P(Y) from 1 to get P(not Y), resulting in a probability of 0.85.
The question asks us to find the probability of not event Y occurring, given that X and Y are mutually exclusive events, and we're provided with P(X) and P(X or Y). Since X and Y are mutually exclusive, the sum rule of probability states that P(X or Y) = P(X) + P(Y). Using the given values, we can express P(Y) as P(X or Y) - P(X), which is 0.7 - 0.55 = 0.15. Since the probability of an event and its complement sum to 1, P(not Y) is 1 - P(Y), which gives us 1 - 0.15 = 0.85.
Therefore, the probability of not Y is 0.85.

There are students in three rows taking a test. there are 22 students in the first row, 19 students in the second row, and a certain number of students in the third row. if there are a total of 62 students, how many students are in the third row?
To determine how many students are in the third row, subtract the sum of the students in the first two rows (22 + 19 = 41) from the total number of students (62). The result is that there are 21 students in the third row.
The student is asking a question related to basic arithmetic, specifically subtraction and problem-solving skills. To find out how many students are in the third row, we subtract the number of students in the first two rows from the total number of students. There are 22 students in the first row and 19 in the second row. The total number of students is 62.
So, we calculate the number in the third row as follows:
Calculate the combined number of students in the first two rows: 22 (first row) + 19 (second row) = 41 students.Subtract the number of students in the first two rows from the total number of students: 62 (total) - 41 (combined first and second rows) = 21 students.Therefore, there are 21 students in the third row.

A psychology class consists of 14 males and 36 females. if the professor selects names from the class list using random sampling, what is the probability that the first student selected will be a female? if a random sample of n = 3 students is selected and the first two are both females, what is the probability that the third student selected will be a male?
Final answer:
The probability of selecting a female first from a class with 14 males and 36 females is 0.72. If the first two students selected are females, the probability that the third student will be a male is approximately 0.292.
Explanation:
The subject of this question is Mathematics, specifically dealing with the concept of probability in a high school level. We are to determine two probabilities: the chance of selecting a female student first from a class, and the likelihood of selecting a male student third given that the first two selected were females.
To find the probability of selecting a female first, we need to consider the total number of students and the number of females. The class has 14 males and 36 females, so the total number of students is-
14 + 36 = 50
The probability of selecting a female first is therefore the number of females divided by the total number of students, which is-
36/50 or 0.72
For the second probability, since the first two students selected are females, we now have a reduced pool of 34 females and 14 males, with a new total of 48. The probability of the third student being a male is then 14/48, which simplifies to 0.292 approximately.

What is the measure of ∠F?
What is the measure of ∠R?
What is the measure of ∠C?
Answer: The measure of ∠F=55°
The measure of ∠R=36°
The measure of ∠C=43°
Step-by-step explanation:
The angle sum property of triangle say that the sum of all the interior angles of a triangle is 180 degrees.Therefore By using angle sum property in Δ RST
∠R+∠S+∠T=180°
⇒∠R+76°+68°=180°
⇒∠R=180°-144°
⇒∠R=36°
In Δ CDE, where ∠C is a right angle.
∠C+∠D+∠E=180°
⇒∠C+90°+47°=180°
⇒∠C=180°-137°
⇒∠C=43°
In ΔDEF
∠D+∠E+∠F=180°
⇒104°+21°+∠F=180°
⇒∠F=180°-125°
⇒∠F=55°
Which of the following is a true statement a.5/6>10/12
B.6/9=1./3
C.13/15>4/5
D.1/4>1/3
The true statements among the given statement by converting them as like fractions is equal to option c. 13/15 > 4/5.
To compare fractions, it's helpful to have them with the same denominator.
Let's convert each fraction to a common denominator, and then we can compare them:
a. 5/6 > 10/12
Common denominator for 6 and 12 is 12:
5/6 = 10/12
So, a is not true.
b. 6/9 = 1/3
Both fractions are simplified and convert to have same denominator (9),
6/9 and 3/9
6/9 > 3/9
so b is not true.
c. 13/15 > 4/5
Both fractions are simplified and convert to have the same denominator (15),
4/5 = 12/15
13/15 > 12/15
and we can see that 13/15 is greater than 4/5, so c is true.
d. 1/4 > 1/3
To compare these fractions, we need a common denominator, which is 12:
1/4 = 3/12
1/3 = 4/12
Now we can see that 1/3 is greater than 1/4, so d is not true.
Therefore, the true statements is option c. 13/15 > 4/5.

Given that the legs of a right triangle measure a and b and the hypotenuse of the triangle measures c, what does the Pythagorean Theorem state about the sides of this triangle? a2 + c2 = b2 a2 − b2 = c2 2a + 2b = 2c a2 + b2 = c2
The Pythagorean Theorem establishes the relationship between the sides of a right triangle, highlighting that the sum of the squares of the two shorter sides equals the square of the hypotenuse.
The Pythagorean Theorem states that in a right triangle, the sum of the squares of the two shorter sides (legs) is equal to the square of the longest side (hypotenuse). In mathematical terms, it is represented as a² + b² = c². This relationship applies to all right triangles and is fundamental in geometry.

A line blank has endpoints
Answer: A line never has endpoints .
Step-by-step explanation:
In geometry , a line is a straight one-dimensional undefined figure which extends infinitely in both directions.
Thus , a line contains no endpoints because it is extending infinitely in both the directions.
If a line has one end point then we call it a ray and if it has both endpoints then we call it line-segment.
Therefore , the complete sentence will be : A line never has endpoints

Which lines are parallel in the square pyramid?
Select each correct answer.
BC←→ and DE←→
CD←→ and BE←→
AD←→ and BC←→
AB←→ and AD←→
A square pyramid is a pyramid with a square base. In this problem, this base is formed by the points B, C, D and E as illustrated in the Figure above. So, the correct answers are:
First. (BC←→ and DE←→)
This is indicated in Figure 1. As you can see, the red lines are parallel, that is:
[tex]\overline{BC} \ is \ parallel \ to \ \overline{DE}[/tex]
Recall that two lines are parallel if they are always the same distant apart in which case they are equidistant, that is, they never meet.
Second. (CD←→ and BE←→)
This is indicated in Figure 2. As you can see, the green lines are parallel, that is:
[tex]\overline{CD} \ is \ parallel \ to \ \overline{BE}[/tex]
Answer: The correct options are
(A) BC←→ and DE←→
(B) CD←→ and BE←→
Step-by-step explanation: We are given to select each pair of sides that are parallel to each other in the square pyramid.
We know that
the base of a square pyramid is a square. And the opposite sides of a square are parallel to each other.
So, in the given square pyramid ABCDE, the base is a square BCDE.
Therefore, the pair of parallel sides are
BC and DE ; CD and BE.
This implies that option (A) and (B) are correct.
Thus, the correct options are (A) and (B).
