The common difference is essentially what u need to add to one number in the sequence to get the next
So previous number + common difference = next number after that
The common difference would be -8
For a trapezoid, the area is:
S=(b+B)h/2, where b and B are the bases, and h is the height.
b=2
B=2+2+2=6
h=2.
S=(2+6)×2/2=8
The ratio here is 16:436.
The easiest way to solve this is finding how many miles Jim can drive using just 1 gallon. We can do this by dividing both sides of the ratio by 16.
16÷16 is 1
436÷16 is 27.25
so our new ratio is 1 gallon:27.25 miles.
next we simply multiply both sides by 14.
1x14=14
27.25x14=381.5 miles :)
Answer:
Below.
Step-by-step explanation:
A. Required probability = 11/80.
B. 3700 * 11/80 = 508.75 so the predicted number would be 509.
