A. The mean and the median are the same.
B. The mean is greater than the median.
C. The mean is less than the mode.
D. The mean is less than the median.

Answers

Answer 1

Answer: B



Step-by-step explanation: Trust me

Mean (Average) 62.333333333333

Median 60

oWhat can I say execpt your welcome

Answer 2

The mean is greater than the median.

Option (B) is correct.

To find the statements is true.

What is statistics?

A branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data.

Half the students scored 55.

The next highest score is 60. So the median is (55+60) / 2 = 57.5.

A few students scored 72, so the mean is slightly greater than the mean of 55 and 60.

Therefore, the mean is greater than the median.

Answer:

x should be 55

Step-by-step explanation:

the acute angle is 55 and we know that the whole horizontal is 180 so calculate 180-55 to find the obtuse angle which is 125. Then subtract 70 from that to isolate for x and you get 55.

They are a linear pair so they equal 180 so 55+70=125 and 180-125=55 so x= 55

What are the mean, variance, and standard deviation of these values? Round to the nearest tenth. 12, 13, 15, 4, 11, 12
Plz help

Answers

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

A taxi driver charges you $1.50 for the first mile and $.90 for each additional mile. How far could you go for $20.00 if you give the driver a $2.00 tip?

Answers

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.

18x−72=6x+12

Step 2: Subtract 6x from both sides.

18x−72−6x=6x+12−6x

12x−72=12

Step 3: Add 72 to both sides.

12x−72+72=12+72

12x=84

Step 4: Divide both sides by 12.

12x/12=84/12
