Since the person didn't write the answer choices they were:

A. On average, city A was warmer than city B.

B. The median and mode are different for city B.

C. The temperature range between the maximum and minimum values for city A is greater than the temperature range between the maximum and minimum values for city B.

D. The median is less for city A than for city B.

I believe it is A personally cause i took the test and got it right

Answer:

  1. On average city A is warmer than city B
  2. The median and mode are same for city B.
  3. The temperature range between the maximum and minimum values for city B is greater than the temperature range between the maximum and minimum values for city A.
  4. The median is less for city B than for city A.                

Step-by-step explanation:

We are given the following information in the question:

City A: 90  85  84  85  80  82  83  85  89  82

City B:  77  78  98  91  78  76  78  85  84  71

Formula:

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}

Mode is the most frequent observation

City A:

Mean =\displaystyle\frac{845}{10} = 84.5

Median:

Sorted data: 80, 82, 82, 83, 84, 85, 85, 85, 89, 90

Median = \frac{84+85}{2} = 84.5

Mode = 85

Minimum = 80

Maximum = 90

Range = Maximum - Minimum = 10

City B:

Mean =\displaystyle\frac{816}{10} = 81.6

Median:

Sorted data: 71, 76, 77, 78, 78, 78, 84, 85, 91, 98

Median = \frac{78+78}{2} = 78

Mode = 78

Minimum = 71

Maximum = 98

Range = Maximum - Minimum = 27

Thus, we can say that:

  • On average city A is warmer than city B
  • The median and mode are same for city B.
  • The temperature range between the maximum and minimum values for city B is greater than the temperature range between the maximum and minimum values for city A.
  • The median is less for city B than for city A.

Calculate the data value that corresponds to each of the following z-scores.
Fynjy0 [20]

Answer:

a) 90.1

b) $35.6

c) 3.0915 hours

Step-by-step explanation:

The z-score measures how many standard deviations a score X is above or below the mean.

It is given by the following formula:

Z = \frac{X - \mu}{\sigma}

In which \mu is the mean and \sigma is the standard deviaition.

In all three cases, we have to find X

a. Final exam scores: Allison’s z-score = 2.30, μ = 74, σ = 7.

Z = \frac{X - \mu}{\sigma}

2.30 = \frac{X - 74}{7}

X - 74 = 7*2.3

X = 90.1

b. Weekly grocery bill: James’ z-score = –1.45, μ = $53, σ = $12.

Z = \frac{X - \mu}{\sigma}

-1.45 = \frac{X - 53}{12}

X - 53 = -1.45*12

X = 35.6

Mean and standard deviation in dollars, so the answer also in dollars.

c. Daily video game play time: Eric’s z-score = –0.79, μ = 4.00 hours, σ = 1.15 hours.

Z = \frac{X - \mu}{\sigma}

-0.79 = \frac{X - 4}{1.15}

X - 4 = -0.79*1.15

X = 3.0915

Mean and standard deviation in hours, answer in hours.

Eli walked 12 feet down the hall of his house to get to the door. He conti in a straight line out the door and across the yard t
EastWind [94]

Answer:

a. Check the diagram

b. He walked 58 feet

c. He is 18 feet far away from the house

Step-by-step explanation:

a. Eli started inside the house an walked 12 feet (blue arrow), after that he keep walking until the mailbox for 32 feet (green arrow) and after that he came back until the dog 14 feet (red arrow).

b. For calculating how far has he walked we need to take into acount all the travel so we add all the arrows:

12ft + 32ft + 14ft =58ft

He walked 58 feet.

c. The distance from the dog to the house is determine by the substraction between the distance to the mailbox with the distance he walked to the dog then:

32ft - 14ft = 18ft.

He is 18 feet far away from the house.

Evaluate the expression x²+yz for x=-3, y=5, and z=2
Over [174]

Answer:

I think that the answer is 19.

Step-by-step explanation:

Writing out the problem

x²+yz

Substituting the given values of the variables

(-3)²+(5)(2)

Simplifying (-3)², which is 9

9+(5)(2)

5 times 2 equals 10

9+10

19

In circle Q with
jonny [76]

Answer:

The minor arc PR is 42 degrees

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The inscribed angle is half that of the arc comprising

so

m\angle PSR=\frac{1}{2}(arc\ PR)

we have

m\angle PSR=21^o

substitute

21^o=\frac{1}{2}(arc\ PR)

arc\ PR=21(2)=42^o

Remember that the minor arc in a circle is less than 180 degrees

therefore

The minor arc PR is 42 degrees
