Note that the chances of a head and a tail appear in a single toss is 1/2
(1/2)^3 =0.125
Answer:
3 trips
Step-by-step explanation:
We would divide the amount of riders the roller coaster could take in a single trip by the total number of riders to determine how many trips it can make.
max amount of riders/total riders
72/24 = 3
Hence, the rollercoaster made 3 trips.
Answer:
C. 
Step-by-step explanation:
Given problem is 
.
Now we need to evaluate the given limit.
If we plug 
, into given problem then we will get 0/0 form which is an indeterminate form so we can apply L Hospitals rule
take derivative of numerator and denominator
=2
Hence choice C is correct.
Answer:
79 units²
Step-by-step explanation:
The area of a circle is found by using the formula A = π x r². Since we are not given the radius we can use the formula r = C / (2π). Substituting in the given values, we get r = 31.5/(2π). 2 times pi is 6.283185307. 31.5 divided by this will get you 5.013380707. Now, put that value in for r in the area equation. A = π x 5.013380707². Pi times 5.013380707² equals 78.96074613. This can be rounded to 79. (Or 80 if you need to the nearest whole number.)
Answer:
x=3
y=7
Step-by-step explanation:
solve for the first variable in one of the equations, then substitute the result into the other equation.
