Given from the graph we can say that:

The process of acquiring, storing, and displaying data in a way that makes it easy for others to use (read or fetch data), such as in graphs or charts, is known as data handling. Statistics is another name for it. Additionally, it is employed for data comparison and mean, median, and mode extraction.

(i) maximum number of students watching TV  =32

Almost 32 students watched TV for 4-5 hours.

(ii) For students watching TV for less than 4 hours = ?

= 4 ₊ 8 ₊ 22

= 34

(iii) students who spent more than 5 hours watching  TV = ?

= 8 ₊ 6

= 14

Hence we get the desired answers.

The average number of viewers over the two weeks written in scientific notation is 3.85 × 10^8. option C

Average number of viewers over the two weeks = (First week + Second week) / 2

= {(3.6 x 10⁴) + (4.1 x 10⁴)} / 2

= {3.6 + 4.1 × 10^(4×4) } / 2

= (7.7 × 10^16) / 2

= 3.85 × 10^8

Answer:

child: 74 adult: 117 student: 37

Step-by-step explanation:

x=2z

x+y+z=191

7.5x+9.75y+8z=1593.5

The number of tickets sold for child is 86.

The number of tickets sold for adults is 62.

The number of tickets sold for child students is 43.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Total tickets sold = $1593.50 _____(1)

Total number of tickets sold = 191 _____(2)

Let the number of tickets sold for child = P _____(3)

Let the number of tickets sold for adults = Q _______(4)

Let the number of tickets sold for students = R ______(5)

Cost of child ticket = $7.50 ______(6)

Cost of adult tickets = $9.75 ______(7)

Cost of student tickets = $8 _______(8)

We can make equations as:

From (2), (3), (4), and (5)

P + Q + R = 191 ____(9)

From (1), (6), (7), and (8)

7.50P + 9.75Q + 8R = 1593.50 _____(10)

We have,

P = 2R putting in (9) and (10)

2R + Q + R = 191

We get,

3R + Q = 191 _____(11)

15R + 9.75Q + 8R = 1593.50

23R + 9.75Q = 1593.50 _____(12)

From (11).

Q = 191 - 3R putting in (12)

23R + 9.75 (191 - 3R) = 1593.50

23R + 1862.25 - 29.25R = 1593.50

-6.25R = -268.75

R = 43 putting in Q = 191 - 3R

We get,

Q = 191 - 3 x 43 = 191 - 129 = 62

Putting R = 43 in P = 2R

We get,

P = 2x43 = 86

We have,

P = 86, Q = 62 and R = 43

Thus,

The number of tickets sold for child is 86.

The number of tickets sold for adults is 62.

The number of tickets sold for child students is 43.

Everything in the parenthesis is simplified, and there isn't any exponent so we onto step 3 which is multiply.

There is a negative infant of the parenthesis -(2x²+8-3x)

that negative sign actually is a -1

therefore multiply -1 to each number inside the parenthesis

The product of a rational number with an irrational number is an irrational number. To see this assume that x is a rational number and y an irrational number. Then let us assume that the product xy is rational, which means that there are integers a,b such that xy=a/b. But then we obtain y=(1/x)(a/b) which is also rational since the set of rational numbers is closed under multiplication. But this is a contradiction since y was assumed to be an irrational number.

The solution to the compound inequality is 1200 < x < 1600 and the meaning is she must keep her calories consumed between 1200 and 1600

The compound inequality is given as

2450 < 2x + 50 and 2x + 50 < 3250

Subtract 50 from both sides of the inequality

So, we have

2400 < 2x and 2x < 3200

Divide through the inequality by 20

So, we have

1200 < x and x < 1600

Combine the inequalities

1200 < x < 1600

Hence, the solution to the compound inequality is 1200 < x < 1600 and the meaning is she must keep her calories consumed between 1200 and 1600

The probability is 1/4 that the winners will be wearing numbers 2, 4, and 7.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

We have been given that a group of 12 dance competition contestants is wearing the numbers 1 through 12.

To determine the probability that the winners will be wearing numbers 2, 4 and 7

Here are favorable outcomes that the contestants wearing numbers 2, 4, and 7

So the number of favorable outcomes = 3

And there is a total number of outcomes = 12

Required probability = 3/12

Required probability = 1/4.

Thus, the probability is 1/4 that the winners will be wearing numbers 2, 4, and 7.

The third term of the arithmetic sequence is 18.

The arithmetic sequence formula can be represented as follows:

nth term = a + (n - 1)d

where

Therefore, 4 numbers are inserted between 4 and 39.

Hence,

a = 4

39 = 4 + 5d

39 - 4 = 5d

35 = 5d

d = 35 / 5

d = 7

Hence, the common difference of the arithmetic sequence is 7.

Answer:

1915

Step-by-step explanation:

nth term = 15n + 400

term to term = 15

n = position

eg:

n=1

1x15=15 + 400 = 415

n=2

2x15=30 + 400 = 430

n=101

101x15= 1515 + 400 = 1915

Answer:

1915

Step-by-step explanation:

formula for the nth term is

an = d times n + first term - d

an = n*d + a1 - d

find the difference between the numbers

it's 15 which is d

first term is a1 which is 415

a101 = 15 times 101 + (415 minus 15)

a101 = 1515 + 400

a101 = 1915

The point-slope form of the equation for the line with a slope of [tex]\frac{6}{19}[/tex] that passes through the point[tex](-1,\frac{7}{5} )[/tex] is [tex]6x-19y=-\frac{163}{5}[/tex]

As per the question statement, we are supposed to find the point-slope form of the equation for the line with a slope of [tex]\frac{6}{19}[/tex] that passes through the point[tex](-1,\frac{7}{5} )[/tex] .

Before solving the question, we need to know about the point - slope form of the line i.e., [tex]y-y_{1} =m(x-x_{1} )[/tex]

where m = slope = [tex]\frac{6}{19}[/tex]

[tex]x_{1} =-1[/tex] and [tex]y_{1} = \frac{7}{5}[/tex]

Now substituting values, we get

[tex]y-\frac{7}{5} =\frac{6}{19} (x-[-1])[/tex]

[tex]y-\frac{7}{5} = \frac{6}{19} (x+1)[/tex]

[tex]19y - \frac{133}{5} = 6x+6[/tex]

Rearranging,

[tex]6x-19y+6+\frac{133}{5} =0[/tex]

[tex]6x-19y+\frac{163}{5} =0[/tex]

[tex]6x-19y=-\frac{163}{5}[/tex]

Hence our required equation is [tex]6x-19y=-\frac{163}{5}[/tex]
