Answer:

mode = 1

median = 2

mean = 3

Step-by-step explanation:

Here in this question, we want to calculate the given measures of central tendencies.

1. Mode

The mode refers to the number that has the highest frequency. The number here is the first number which is 1.

2. Median

This refers to the middle number after the numbers have been arranged in the descending or ascending order. Looking at the numbers, we have the middle number at the 8th term. The number at the 8th term is the number 2

3. Mean

The mean is the average of the numbers. It is calculated by summing up the numbers and dividing by the count of the numbers.

The sum of the numbers is;

1(7) + 2(3) + 3(1) + 5(2) + 8(1) + 11(1) = 45

The count of the numbers is 15

The mean is thus;

45/15 = 3

Answer:

1) 24

2) 42

3) 26

4)44

Step-by-step explanation:

1) 2(8+4) = 2*12 = 24

2) 2(15+6) = 2*21 = 42

3) 2(4+9) = 2*13 = 26

4) 2(12+10) = 2*22 = 44

[tex]= \color{plum}\tt(C) 7 \frac{2}{4} [/tex]

Quantity of water she needs [tex] = \tt \frac{3}{4} \: cup [/tex]

Number of servings she needs = 10

Number of cups of water she will need :

[tex] = \tt \frac{3}{4} \: \times 10[/tex]

[tex] = \tt\frac{30}{4} [/tex]

[tex] =\tt 7\frac{2}{4} \: cups[/tex]

Thus, she needs [tex] \tt 7\frac{2}{4} \: cups [/tex] of water.

Therefore, the correct option is [tex]\color{plum}\tt(C) 7 \frac{2}{4} [/tex]

Answer:

For radio = $40.43

Television =  $444.73

Player =  $364.73

Step-by-step explanation:

The computation of the each device cost is shown below:

let us assume the following things

radio be x

television x + 10x

player x + 10x - $80

Now the equation is

x + x + 10x + x + 10x - $80 = $850

3x + 20x - $80 = $850

23x = $930

x = $40.43

For radio = $40.43

Television = $40.43 + 10(40.43)

= $40.43 + $404.3

= $444.73

and, the player would be

= $444.73 - $80

= $364.73

Answer:12

Step-by-step explanation:

Your goal with variables should always be to isolate them.

so the first step is to subtract the 4

3x^2+4=436

       -4= -4

3x^2=432

The next step to isolate the variable x is to get rid of the 3. To get rid of the 3 you have to divide both sides by 3 since it is the opposite of multiplying.

3x^2=432

/3.    =/3

x^2=144

the last step to isolate the x is to do the opposite of what an exponent is, which is to find the square root. So when you square the x^2, the exponent cancels out.

square root of x^2=x

square root of 144=12

x=12

Answer:

event 5

Step-by-step explanation:

event 5 has a 40% chance of happening, all the others are around 20-30% chances

x = width, y = length

x = 1, y = 5

x = 2, y = 10

x = 3, y = 15

x = 4, y = 20

x = 5, y = 25

Answer:

1

Step-by-step explanation:

Answer:

y=5/6x -3

Explanation:

first subtract -5x from both sides, then divide everything by -6, and boom you have your answer.

Step-by-step explanation:

Answer:

true

Step-by-step explanation:

Answer:

y=6*x+101

Step-by-step explanation:

Slope intercept form is y=mx+n, where m is the slope and n is the intercept.

Substituing in that equation the two points we get two different expressions. Now we have to solve a 2x2 system of equations.

I decide to solve it through substraction (literally one expression minus the other). That way we cancel out the n and obtain the value of m.

Now that we have m we plug in the value of m in one of the expressions to obtain the value of n.

To express the final equation we just plug in the values of m and n in the expression y=mx+n!

Answer:

y=6*x+101

Step-by-step explanation:

The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
