Answer:
The distance is 750 miles.
Step-by-step explanation:
In order to find this, we create a proportion. On the left would be the scale factor. On the right would be the Idaho to Arizona distance.
1in / 300 mi = 2.5in / x mi
Now we can cross multiply to find the distance.
300 * 2.5 = 1 * x
750 mi = x
Use a variable to solve for this.
x * .08 = 3000
Divide by .08 on both sides.
x = 37500
We can check this by inputting 37500 for x.
37500 * .08 = 3000
3000 = 3000
Kenya Kon must earn $37500 to earn $3000.
Answer:
See below.
Step-by-step explanation:
An outlier can affect the mean by a lot. For example, if my neighbor moves out and Bill Gates moves in (he would be a <u>super</u> outlier!), the mean annual income would increase enormously.
The median, on the other hand, would not change at all. The income in the middle is still the income in the middle; Gates' income would not budge the median.
Answer:
length= 3.7 ft.
Step-by-step explanation:
T= (square root of length) * k
1.8 seconds = (square root of 3) * k
k= 1.8 seconds / (square root of 3)
a.) T= (square root of 11) k
substituting k:
T=(square root of 11) * 1.8 seconds / (square of 3)
T= 3.4 seconds
b.) 2 seconds = (square root of length) k
substituting k:
2 seconds =(square root of length) 1.8 seconds / (square root of 3)
Divide the equation by 1.8 seconds / (square root of 3):
2 seconds / [1.8 seconds / (square root of 3)] = (square root of length)
10(square root of 3) / 9 = (square root of length)
square both sides:
100/7 ft= length
length= 3.7 ft.
Hope this helps.
