You change the symbol to its inverse and the second number to its opposite

22 + (-3)

Answer:

E

Step-by-step explanation:

If you add 22 onto the sum of all the points and divide by the amount of games (6), you get 12.

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:

Step-by-step explanation:

Volume of a pyramid = [tex]\frac{1}{3}(\text{Area of the rectangular base})(\text{Height})[/tex]

Area of the rectangular base = Length × Width

                                                = 8 × 6

                                                = 48 mm²

Volume of the pyramid = 192 mm³

192 = [tex]\frac{1}{3}(48)h[/tex]

h = [tex]\frac{192}{16}[/tex]

h = 12 mm

Therefore, all the pyramids having height less than 12 mm will be fitted inside the given pyramid.

Answer:

48 cm^2

Step-by-step explanation:

The area of a trapezoid is calculated using the following formula :

(a+b)2*h (a: base, b: base, h: height)

(8+16)/2*4 = 48 cm^2

Answer:

√3/2 or 0.886025

Step-by-step explanation:

Answer:

V = 18.84 units³

Step-by-step explanation:

The formula for the volume of a cone of base radius r and height h is

V = (1/3)(pi)(r²)(h).

Here, with pi = 3.14, r = 3 and h = 2, we get:

V = 18.84 units³

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:

2000 g/L

Step-by-step explanation:

(10.0 g) / (0.005 L) = 2000 g/L

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.

Step-by-step explanation:

that is correct and right answer.

The sequence 3/4, 4/5, 5/6, 6/7, . . . is diverges option (A)  The sequence diverges is correct.

A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums get closer and closer to a certain number.

The sequence can be defined as the systematic way of representing the data that follows a certain rule of arithmetic.

It is given that:

The sequence:

3/4, 4/5, 5/6, 6/7, . . .

AS we know, the convergent sequence occurs when, as n approaches infinity, you arrive at a final and constant term through a number of terms.

Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.

The nth term of the sequence

a(n) = 2+n/3+n

Applying divergence test:

The sequence diverges

Thus, the sequence 3/4, 4/5, 5/6, 6/7, . . . is diverges option (A)  The sequence diverges is correct.

Answer:

The y-variable will be eliminated when adding the system of equations.

There is only one solution to the system of equations.

Step-by-step explanation:

-x + 6y = 16 (1)

8x - 6y = -2 (2)

Add the equations to eliminate y

-x + 8x = 16 +(-2)

7x = 16 -2

7x = 14

x = 14/7

x = 2

Substitute x = 2 into (1)

-x + 6y = 16 (1)

-2 + 6y = 16

6y = 16 + 2

6y = 18

y = 18/6

y = 3
