Answer:
Step-by-step explanation:
3 sqrt2
The tires are similar in shape. This means that if they undergo the same number of revolutions, the ratio of the distances covered would be equal to the ratio of the radius of each tire.
From the information given,
radius of tire 1 = 9
distance covered by tire 1 = 8482
let radius of tire 2 = r
distance covered by tire 2 = 5654
Thus,
8482/5654 = 9/r
By crossmultiplying, we have
r * 8482 = 5654 * 9
8482r = 50886
r = 50886/8482
r = 5.9993
By rounding to the nearest whole number,
radius of second tire = 6 inches
Answer:
expanded : 3a + 9 + 2a answer: 5a + 9
Step-by-step explanation:
so 3*a = 3a and 3*3 = 9 + 2a
3a + 9 + 2a
5a + 9
The answer is the median m = 117.5.
Explanation:
let's calculate the three central tendency measures:
- mean = μ = (<span>22 + 114 + 115 + 120 + 122 + 125) / 6 = 103
- median = m: we have 6 values, therefore the median will be the average between the third and the fourth value:
</span><span>22 114 115 | 120 122 125
m = (115 + 120) / 2 = 117.5
- mode: all the values appear only once, therefore the mode is not applicable.
Since our values are not symmetrically distributed (we have 22 which differs a lot from the other values), the median should be preferred than the mean as best central tendency measure.

Answer:
3
Step-by-step explanation:
Well, first off I'm assuming that by "scar factor" you mean scale factor. So if the two squares are similar then that means the sides are also similar, that means that they are equivalent. So all you have to do is 12/4 to get 3. So then to check it, you do 4 times 3 which gets you to 12.
So the final answer is 3
