Hello!

Mean: 7 + 5 + 4 + 2 + 1 + 1 + 2 + 3 + 5 + 4 + 5 = 39

 39 ÷ 11 = 3.5

The mean is 3.5

~~~~~~~~~~~~

Median: 1, 1, 2, 2, 3, 4, 4, 5, 5, 5, 7 - Which number is in the center?

The median is 4

~~~~~~~~~~~~~~~~~

Mode: Which number appears most often?

The mode is 5. 

Hope I helped! :3

Hello!

First you need to list the numbers from least to greatest

1, 1, 2, 2, 3, 4, 4, 5, 5, 5, 7

To find the mean you add all the numbers up and divide the sum by the amount of numbers added

1 + 1 + 2 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 7 = 39

39 / 10 = 3.9

The mean is 3.9
------------------------------------------------------------------------------------------------------
To find the median you find the number in the middle

The median is 4
------------------------------------------------------------------------------------------------------
The mode is the number that appears the most

The mode is 5 

Hope this helps!

Oduvanchick [21]

Answer:

  • 20 sin 40°  ≈ 12.86 ft

Step-by-step explanation:

Let the height of the street lamp be x

Opposite angle is 40° and the shadow, the hypotenuse of the formed triangle is 20 ft.

  • sin 40° = x/20
  • x = 20sin 40°
  • x ≈ 12.86 ft

The table shows the temperatures in degrees Celsius, y, inside a shed at x hours past noon. The maximum and minimum temperatures
kolbaska11 [484]

Answer:

B

y = 3 cos (pi/12x - pi/4) + 17

Step-by-step explanation:

First find the average temperature which is 20 + 14/2 = 17

Find the amplitude

20 - 17 = 3

This means that that at noon, the shift is 3hrs past

the best equation that represents this scenario is y = 3 cos (\frac{\pi}{12}x - \frac{\pi}{4}) + 17

PLEASE PLEASE HELP ME ! Jerry wants to buy his grandpa's old car for $500.00. He works 10 hours a week
Juli2301 [7.4K]

Answer:

Step-by-step explanation:

Needs $500  Makes 7.50 and works 10 hours week.

7.50*10= $75.00 a week

500/75= 6.6 weeks or 6 weeks and 2/3 of a week. I'd round to 7 weeks.

75(x)=500   X= weeks needed.

75x=500 if you divide 500 by 75

x=20/3 or 6.6

Ali and Tibor get paid $9 per hour. This week, Tibor made an additional $27 in overtime.
Leviafan [203]
9a + (9t+27)=x

To write it another way you could flip the numbers around:

(9t+27)+9a=x

Or flip the variable to the other side.

x=9a + (9t+27)

Any way you put the numbers as long as x is on the either side, you will get the same answer.

Hope this helps!
