Mode is E. 65 (Remember it's the number you see most.)
Range is D. 26 (Your difference between you highest and lowest number.)
Median is C. 72 (The number in the middle - 62 / 65/ 65 / 68 / (72) / 74/ 75 / 79 / 88)
Mean is C. 72 as well (Just add up all of your number, then divide by the amount that is there. *Solution 648/9 = 72)
You're welcome :)
Figure a is double of figure b, so
16 : 2 =
8 inches
Answer:
142 miles
Step-by-step explanation:
We are given the situation that Jill measured the distance from the western border to the eastern border in inches. And we are being asked how many miles is the actual distance.
So first , lets look at what we have.
The inches : 3.375
and our reference point
1 inch = 42 miles
We first look at the reference point, if 1 inch is 42 miles, how much would be 3.375 inches?
Multiply 3.375 by 42
==> 141.75 miles
Now the last sentence asks us to round the nearest whole number.
So look at the number next to one in the ones place and we see that the number is greater than 7, so we round up. Leaving us with the answer :
142 miles
D = 5/6 sqrt(h)
7 = 5/6 sqrt(h)
42/5 = sqrt(h)
h = (42/5)^2 = 1,764/25 = 70.56
The height of the mast is 70.56 miles
