Answer:

i. Mean = 11.2

ii. Variance = 14.17

iii. Standard deviation = 3.76

Step-by-step explanation:

i. Mean, m = [tex]\frac{sum of the values}{number of the values}[/tex]

                = [tex]\frac{4+11+12+12+13+15}{6}[/tex]

                = [tex]\frac{67}{6}[/tex]

                = 11.2

The mean of the given data is 11.2

ii. Variance = [tex]\frac{sum(x_{i} - m)^{2}}{n-1}[/tex]

where:   [tex]x_{i}[/tex] is the value of the one observation, m is the sample mean and n is the number of data given.

                   = [tex]\frac{[(4-11.2)^{2}+(11-11.2)^{2} + (12-11.2)^{2} + (12-11.2)^{2} + (13-11.2)^{2} + (15-11.2)^{2}] }{6-1}[/tex]

                   = [tex]\frac{[51.84+0.04+0.64+0.64+3.24+14.44]}{5}[/tex]

                   = [tex]\frac{70.84}{5}[/tex]

                   = 14.168

Variance = 14.17

iii. Standard deviation = [tex]\sqrt{Variance}[/tex]

                                     = [tex]\sqrt{14.17}[/tex]

                                     = 3.76

Answer:

You can go 19.33 miles for $20.00 if you give the driver a $2.00 tip.

Step-by-step explanation:

From the information provided, you can say that the total cost of the taxi is equal to the cost of the first mile plus the price for each additional mile for the number of additional miles, which can be expressed as:

c=1.50+0.90(x-1), where

c is the total cost

x is the number of miles

Now, if you want to determine how far you can go for $20 if you give the driver a $2.00 tip, first you have to subtract the tip from the amount you have:

20-2=18

Then, you know that you have $18 for the cost of the taxi and you can replace c with this value and solve for x to find the number of miles:

18=1.50+0.90(x-1)

18-1.50=0.90x-0.90

16.5+0.90=0.90x

17.4=0.90x

x=17.4/0.9

x=19.33

According to this, the answer is that you can go 19.33 miles for $20.00 if you give the driver a $2.00 tip.

Answer:

Step-by-step explanation:

First find the rate of change or slope denoted as m

m=(y2-y1)(x2-x1) we can find the slope with any two points.

m=(35000-25000)/(600-200)

m=10000/400

m=25

Now that we know the slope we can find the y intercept or original cost

C(n)=25n+b, using any point we can solve for b, I’ll use (200, 25000)

25000=25(200)+b

25000=5000+b

b=20000 so now we know the complete equation.

C(n)=25n+20000

Answer C.

Answer:

15 miles per gallon

Step-by-step explanation:

Divide miles travelled by gallons used, that is

90 ÷ 6 = 15 miles per gallon

The rate of the truck is 15 miles per gallon.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a truck travels 90 miles on 6 gallons of gas. The rate of truck will be calculated as:-

Divide miles travelled by gallons used, that is

Rate = 90 ÷ 6

Rate = 15 miles per gallon

Hence, the rateis 15 miles per gallon.

Step-by-step explanation:

each wand = 2 so you add the wands and multiply the wands by 2

then you divide the answer to the last calculation by 4

which is 28 divided by 4

which = 7

The mean of the data is 7.

The simplest and most popular way to measure a mean or average is the arithmetic mean. It simply entails adding up a collection of numbers, then dividing that total by the total number of numbers in the series.

Given:

Glenda = 2 x 2= 4 wands

Tink = 3 x 2= 6 wands

Merry = 4 x 2= 8 wands

Gracie = 5 x 2= 10 wands'

So, Arithmetic Mean = (Sum of wands) / (Total number of wands)

                                  = (4+ 6 +8 + 10)/4

                                  = 28/4

                                  = 7

Hence, the mean is 7.
