Answer:
The answer is 35.8
Step-by-step explanation:
You are using left riemann sum, meaning you take the area of each rectangle by the left side. Multiply the widths by heights then add together:
2(5.7) + 3(5.0) + 2(2.0) + 4(1.2) + 1(0.6)
=35.8
Answer:
1/64
Step-by-step explanation:
We want a second H in the 9th toss. So, we must get only 1 H in the first eight tosses.
So, in the first 8 tosses, we have 1 H and 7 T. Number of ways of getting 1 H and 7 T is 8!/7! = 8
Total possible outcomes = 2^9 = 512
Required probability = 8/512 = 1/64

<span>This problem is solved using dimensional analysis. It is known that there are 5280 yards in a league and that there are 3 feet in one yard. Finally, it is known that there are 6076 feet in one nautical mile. As a result, we can multiply these dimension together, making certain that the units cancel and leave us with only nautical miles.
It is done as follows:
(610 leagues)(5280yds/1 league)(3 ft/1yd)(1 nautical mile/6076ft)= 1590 naurtical miles.</span>
Answer:
-12y + 20
Step-by-step explanation:
First, you simplify each term:
apply the distributive property:
4 - 5y - 2 (3.5y) - 2 x -8
Multiply 3.5 by -2:
4 - 5y - 2 (3.5y) - 2 x -8
Multiply -2 by -8:
4 - 5y - 7y +16
Next, we simplify by adding terms:
Add 4 + 16:
-5y - 7y + 20
Subtract 7y from 5y:
-12y + 20
Hence the simplified form is -12y + 20
