Answer:

  • Mean = 16.9
  • Mode = 18
  • Median = 17.5

Step-by-step explanation:

<u>Given data:</u>

  • 18, 19, 16, 18, 14, 17, 18, 15

<u>The data in the ascending order:</u>

  • 14, 15, 16, 17, 18, 18, 18, 19

<u>The mean:</u>

  • (14 + 15 + 16 + 17 + 18*3 + 19)/8 = 16.9 (rounded)

<u>The median:</u>

  • (17 + 18)/2 = 17.5 (the average of middle terms)

The value of a certain rare stamp is 160% of its value three years ago if the stamp is worth $220 then what is it’s worth today
xz_007 [3.2K]

Answer:

572$

100% of 220 is 220 so add them together. Then find 60 % of 220. To find 10% of a number move the decimal to the left one time. Which is 22. After that, multiply 22 by 6 because it's 60%. then ad 220+220+132=572.

Robin can mow a lawn in 3 hours, while Brady can mow the same lawn in 4 hours. How many hours would it take for them to mow the
BaLLatris [955]
The answer is <span>twelve sevenths (12/7)
</span>
x - the job<span>
t - time to do the job x

</span><span>Robin can mow a lawn in 3 hours: x/3 * t
</span><span>Brady can mow the same lawn in 4 hours: x/4 * t

</span><span>If they work together, the total work will be the sum of their speeds:
</span>x = x/3 * t + x/4 * t = (x/3 + x/4)*t = (4x/12 + 3x/12) * t = 7x/12 * t

x = 7x/12 * t

Divide both sides by x:
x/x = 7x/12 * t/x
1 = 7/12 t
t = 1 : 7/12
t = 12/7

43. Consider the equation 4(x-8)+y=9(x-2)
xxMikexx [17]

The expression of the equation 4(x - 8) + y = 9(x - 2) in slope intercept form is; y = 5x + 14

<h3>How to write an equation in Slope Intercept form?</h3>

We want to express 4(x - 8) + y = 9(x - 2) in slope intercept form of y = mx + b.

Let us expand the equation to get;

4x - 32 + y = 9x - 18

Isolate y to get;

y = 9x - 4x - 18 + 32

y = 5x + 14

Thus;

Slope = 5

y - intercept = 14

x - intercept = -2.8
