Answer:
24 students per mile
Step-by-step explanation:
Given in the question,
Length of rectangle for building university = 75 miles
Width of rectangle for building university = 25 miles
Total area:
Length x Width
= 75 x 25
= 1875 miles²
Only 70% of the buildings at this university are used for instruction
70% of 1875 miles²
70/100 x 1875
= 1312.5 miles²
32,125 students are enrolled at this university
So,
1312.5 miles² = 32,125 students
1 mile = 32,125/1312.5
= 24 students per mile
Answer:
-3/4
Step-by-step explanation:
Answer:
a) You roll a die 25 times. Let X be the number of times that you roll "3".
* Is a Binomial
b) The SJSU football team will play 12 games next season. They have a 70% chance of winning each conference game and a 60% chance of winning each nonconference game. Let X be the number of games the SJSU football team wins next season.
* Not a Binomial because probability of success is not constant
c) Evelyn has a 75% chance of getting an A in each class she takes. Let X be the number of times Evelyn earns an A during four years at SJSU.
* Is a Binomial
Step 1: Find the value of one variable in terms of the other.
Step 2: Substitute the value you just found for this variable in the other equation.
Step 3: Use your new value for the second variable to find the first.
Now that we know the values for a and b we can find the value of 4a+b.
