[tex]\frac{27}{x} =\frac{36}{28} \\\\x =\frac{27*28}{36} = \frac{3*28}{4} =3*7 =21[/tex]
Answer:
x = 21
Step-by-step explanation:
The parallel lines divide the transversals proportionally, that is
[tex]\frac{27}{x}[/tex] = [tex]\frac{36}{28}[/tex] ( cross- multiply )
36x = 756 ( divide both sides by 36 )
x = 21

A company sells T-shirts for $11 each and sweatshirts for $19 each.The number of T-shirts sold was 10 fewer than three times the number of sweatshirts sold. The T-shirts and sweatshirts sold for a total of $1,970. How many T-shirts were sold?
T-shirts
Answers
Answer:
Number of T-SHIRT sold = x = 110
Number of sweatshirt = y = 40
Step-by-step explanation:
Let
Number of T-SHIRT sold = x
Number of sweatshirt = y
The number of T-shirts sold was 10 fewer than three times the number of sweatshirts sold.
x = 3y - 10
Cost of each T-SHIRT = $11
Cost of sweatshirt = $19
Total cost = $1,970
Total = x + y
1,970 = 11(3y - 10) + 19y
1970 = 33y - 110 + 19y
1970 + 110 = 33y + 19y
2080 = 52y
y = 2,080/52
y = 40
Substitute y = 40 into
x = 3y - 10
x = 3(40) - 10
x = 120 - 10
x = 110
Number of T-SHIRT sold = x = 110
Number of sweatshirt = y = 40
Answer:
110

Step-by-step explanation:
Answer:
MaybeStep-by-step explanation:
The probability that it will not rain will be 0.15.Because Total probability is equal to 1 and the probability of rain is 0.85.So,P(it will not rain) = 1- P(it will rain)We will subtract the probability of rain from the total probability to get the answer for the probability that it will not rain.P(it will not rain) = 1- 0.85P(it will not rain) = 0.15there are 30 students in a class. of those, 15 take history, 18 take geography, and 5 take neither of
these subjects. how many students
take both subjects?
.
Answers
Answer:
n(U)=30
n(H)=15
n(G)=18
n(H ∪ G)'=5
n(H ∪ G)=n(U)-n(H ∪ G)'
=30-5=25
So ,n(H ∩ G)=n(H)+n(G)-n(H ∪ G)
=15+18-25=8
Therefore, 8 students take both subjects.
A set is a mathematical model for a collection of diverse things. The total number of students who who take both History and Geography is 8.
What is a set?A set is a mathematical model for a collection of diverse things; it comprises elements or members, which can be any mathematical object: numbers, symbols, points in space, lines, other geometrical structures, variables, or even other sets.
Given that there are 30 students in a class. of those, 15 take history, 18 take geography, and 5 take neither of these subjects. Therefore, we can write the following values,
Total students, n(S)=30Students who take History, n(H)=15Students who take Geography, n(G)=18Students who take neither of the subject, n(H' ∪ G') =5Now, the number of students who take at least one of the two subject can be written as,
Students who choose at least one subject
= Total students - Students who take neither of the subject
n(H ∪ G) = n(U) - n(H ∪ G)'
n(H ∪ G) = 30 - 5
=25
Further, the total number of students who who take both the subjects can be written as,
Students who take both the subjects = Students who take History + Students who take Geography - Students who choose at least one subject
n(H ∩ G) = n(H) + n(G) - n(H ∪ G)
n(H ∩ G) = 15 + 18 - 25
n(H ∩ G) = 8
Hence, the total number of students who who take both History and Geography is 8.

The value of coefficient of correlation coefficient is -0.953 which is a negative correlation between x and y option (A) is correct.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
We have given data in the table.
As we know, the formula for the correlation is given by:
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
After plugging the value, we will get the value of r:
r = -0.953
Thus, the value of coefficient of correlation coefficient is -0.953 which is a negative correlation between x and y option (A) is correct.

Kailynn has a bag with an equal number of red, yellow, and blue marbles. She
makes a tree diagram to show the sample space if she randomly selects two
marbles out of the bag.
What is the probability that both marbles selected are different colors?
Answers
Answer:
6/9
Step-by-step explanation:
Probability is the likelihood or occurrence of an event. Probability is the ratio of the total number of possible outcomes to the total outcomes. That is:
Probability = total possible outcomes / total outcomes
From the tree diagram we can see that:
total outcomes = {RR, RY, RB, YR, YY, YB, BR, BY, BB} = 9
getting different colors = {RY, RB, YR, YB, BR, BY} = 6
Therefore, the probability that both marbles selected are different colors = number of different colors / total outcomes
The probability that both marbles selected are different colors = 6 / 9

What is the equation of the circle with: center (5, 7) & point on the circle: (-2, 8)?
Answers
Answer: (x - 5)^2 + (y - 7)^2 = 50
Step-by-step explanation:
The general equation for a circle is (x - a)^2 + (y - b)^2 = r^2 where (a, b) is the centre
Use Pythagoras to find r^2
r^2 = (5 - -2)^2 + (7 - 8)^2
= 7^2 + (-1)^2
= 50
So the circle is (x - 5)^2 + (y - 7)^2 = 50

Measures of∠QTR, ∠RQS, m arcTS and m arcQT are 55°, 47°, 102° and 54° respectively.
What is angle?An angle is formed when two straight lines intersect at a point. The amount of "spread" between these two rays is called the "angle". It is represented by the symbol ∠. Angles are usually measured in degrees and radians. This is a measure of roundness or rotation.
Given,
In circle P,
m arcQR = 110°
m arcRS = 94°
∠QRT = 27°
Measure of arc is twice to the angle made by arc on boundary of the circle.
m arcQR = 2∠QTR
110° = 2∠QTR
∠QTR = 110/2
∠QTR = 55°
m arcRS = 2∠RQS
94° = 2∠RQS
∠RQS = 94°/2
∠RQS = 46°
m arcQT = 2∠QRT
m arcQT = 2(27°)
m arcQT = 54°
sum of all arcs made on a circle is 360°
m arcQT + m arcTS + m arcRS + m arcQR = 360°
54° + 94° + 110° + m arcTS = 360°
m arcTS = 360° - 258°
m arcTS = 102°
Hence, 55°, 47°, 102° and 54° are measures of∠QTR, ∠RQS, m arcTS and m arcQT respectively.

The question is asking the probability of rolling a number less than 3 and a consonant.
Well, there are 2 numbers less than 3 on the number cube, 2 and 1. So of the six numbers, 2 of them are less than 3 (2/6).
There are 3 consonants on the spinner. So, of the 4 letters, 3 of them are constants (3/4).
