Answer:

A = 4.5

B = 40.5

C = 4π or 12.566

D = 16

Step-by-step explanation:

<u><em>A</em></u>

6 x .5 = 3

3 x .5 = 1.5

1.5 x 3 = 4.5

<u><em>B</em></u>

12 x 3/4 = 9

1/2 (9)(9) = 40.5

<u><em>C</em></u>

8 x .25 = 2

π2² = 4π or 12.566

<u><em>D</em></u>

24 x 1/3 = 8

6 x 1/3 = 2

2 x 8 = 16

VARVARA [1.3K]

Answer:

The problem is about cases of diabetes in old people through months.

The variable is descrete , because it doesn't admit decimal numbers, it represents people, and people are whole numbers.

The frequency table would be

<h3> Months              People</h3>

January                       24

February                     30

March                          20

April                             18

May                             28

June                             12

The total number of people is 132.

The mean would be the total number of people divided by the six months.

\mu = \frac{132}{6} =22

Therefore, the mean is 22 people per month.

Remember that the median is the value at the center of the data set, which is between March and April, so

\frac{20+18}{2}=19

Therefore, the mean is 19.

The third statistical value is determined by the major frequency. So, the data that repeats the most is February, which means that month encloses the majority of people.

iVinArrow [24]

Answer:

10:02:24\ \text{pm}

Step-by-step explanation:

d = Distance to travel = 880 miles

s = Average speed of the car = 65 mph

Time taken to cover the distance is

t=\dfrac{d}{s}\\\Rightarrow t=\dfrac{880}{65}\\\Rightarrow t=\dfrac{176}{13}\ \text{h}=13.54\ \text{hours}

Time the car stopped

3\times 10+60=90\ \text{minutes}=1.5\ \text{hours}

Total time of the journey

13.54+1.5=15.04\ \text{hours}

Converting 0.04\ \text{hours} to minutes

0.04\times 60=2.4

So, the total time taken for the journey is 15\ \text{hours and }2\ \text{minutes and }24\text{seconds}

Time when they reach their destination

7:30+15:2.4\approx 10:02:24\ \text{pm}

Solve the System and write the solution as an ordered pair. <br><br> 3x+3y=6 <br> 5x-6y=15
Ugo [173]

\\ \sf\longmapsto 3x+3y=6\dots(1)

\\ \sf\longmapsto 5x-6y=15\dots(2)

Multiply eq(1) by 2 and eq(2) by 1

\\ \sf\longmapsto 6x+6y=12

\\ \sf\longmapsto 5x-6y=15

  • Add

\\ \sf\longmapsto 11x=27

\\ \sf\longmapsto x=\dfrac{27}{11}

Now

Put in eq(1)

\\ \sf\longmapsto 3\dfrac{27}{11}+3y=6

\\ \sf\longmapsto \dfrac{81}{11}+3y=6

\\ \sf\longmapsto 3y=6-\dfrac{81}{11}

\\ \sf\longmapsto 3y=\dfrac{66-81}{11}

\\ \sf\longmapsto 3y=\dfrac{15}{11}

\\ \sf\longmapsto y=\dfrac{15}{33}
