Measures of∠QTR, ∠RQS, m arcTS and m arcQT are 55°, 47°, 102° and 54° respectively.

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.

Step-by-step explanation:

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.

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,

Now, 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.

Answer:

44.10 = 2.1x

x = 21 miles

Step-by-step explanation:

Cost per mile = $2.1

Driver tip = $5

Total amount paid = $49.10

Let

x = number of miles

​Write an equation to determine the distance in miles \left(x\right)(x) between the airport and Anna's home.

Total cost of miles = Total amount paid - Driver tip

= $49.10 - $5

= $44.10

Equation to determine distance in miles

Total cost of miles = cost per mile * number of miles

44.10 = 2.1x

Find the distance between the airport and Anna's home

44.10 = 2.1x

Divide both sides by 2.1

44.10 / 2.1 = 2.1x / 2.1

21 = x

x = 21 miles

The experimental probability in simplest form that the number cube shows 6 will be 3/10.

Probability is a branch of mathematics that deals with the occurrence of a random event.

According to the question

Dave rolled a number cube 10 times and recorded the frequency of each result in this table.

From the table it can be seen that the frequency of rolling a 6 is 3 and the probability of the event occuring is 1/6

so ,

The experimental probability in simplest form that the number cube shows 6 will be

= Frequency / No. of times the dice is rolled

= 3/10

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

Step-by-step explanation:

The value of coefficient of correlation coefficient is -0.953 which is a negative correlation between x and y option (A) is correct.

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.

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

Answer:

42.7%

Step-by-step explanation:

Correlation is a statistical measure of inter relationship between two variables' co movement.

Correlation coefficient denotes the direction & extent by which two variables' (same or opposite) movement is linked to each other.

Coefficient of determination = r^2 symbolises percentage of variation in one variable, that can be explained by variation in other variable.

So, in this case r^2 = (0.654)^2 = 0.427716 ; Hence approx 42.7% variation in one variable can be explained by variation in other.

Answer:

(x + 4)(x - 4)

Step-by-step explanation:

There are actually quite a lot of pairs of binomials the disproves Eric's conclusion, but they all model after the same special product: a^2 - b^2.

The special product a^2 - b^2 can be factored into (a + b)(a - b) and for all real a and b, it will come out as a binomial.

Here is an example:

(x + 4)(x - 4)

We can use the distributive property to get:

x^2 - 4x + 4x - 16

which is the same as

x^2 - 16

This would disprove Eric's conclusion.
