In a race a bicycle travels 3/4 of a mile in 1/4 hour determine the unit rate for the speed in miles per hour

The speed of the bicycle is 3 miles per hour

Step-by-step explanation:

Step 1

Determine the distance covered, and the time the bicycle takes as shown;

distance=3/4 miles

time=1/4 hours

Step 2

Derive the expression for the speed of the bicycle as follows;

S=D/t

where;

S=speed in miles per hour

D=distance traveled in miles

t=time taken in hours

In our case;

D=3/4 miles

t=1/4 hour

replacing;

S=(3/4)÷(1/4)=(3/4)×(4/1)=3 miles per hour

The speed of the bicycle is 3 miles per hour

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
