Answer:

82 revolutions Step-by-step explanation:

One revolution will be the circumference of the tire, so multiply pi (3.1416) times the diameter (26 in.) to get 81.68 in. then round it up to 82.

Answer:

a) $s= 9.74$

D. 9.74

b) $Median= 74$

B. 74

Step-by-step explanation:

Part a

We have the following dataset given:

69 74 75 62 70 93 64 69 61 88 67 77 87 90 66 91 77 63 82 82 71 74 76 65 83

We can begin calculating the sample mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X = 75.04$

Now we can calculate the sample deviation with the following formula:

$s =\sqrt{\frac{\sum_{i=1}^n (X_i-\bar X)^2}{n-1}}$

And after replace we got:

$s= 9.74$

Part b

For this case we need to sort the value on increasing way:

[1] 61 62 63 64 65 66 67 69 69 70 71 74 74 75 76 77 77 82 82 83 87 88 90 91 93

And the median would be the value in the position 13 and we got:

$Median= 74$

What value of x makes the equation 8(1.5x - 6) = 2x - 0.5(24 - 16x? true?

nydimaria [60]

Answer:

x=18

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

8(1.5x−6)=2x−0.5(24−16x)

(8)(1.5x)+(8)(−6)=2x+(−0.5)(24)+(−0.5)(−16x)(Distribute)

12x+−48=2x+−12+8x

12x−48=(2x+8x)+(−12)(Combine Like Terms)

12x−48=10x+−12

12x−48=10x−12

Step 2: Subtract 10x from both sides.

12x−48−10x=10x−12−10x

2x−48=−12

Step 3: Add 48 to both sides.

2x−48+48=−12+48

2x=36

Step 4: Divide both sides by 2.

2x/2=36/2

x=18

Answer:

x=18
