Answer:
a) 0.70
b) 0.82
Step-by-step explanation:
a)
Let M be the event that student get merit scholarship and A be the event that student get athletic scholarship.
P(M)=0.3
P(A)=0.6
P(M∩A)=0.08
P(not getting merit scholarships)=P(M')=?
P(not getting merit scholarships)=1-P(M)
P(not getting merit scholarships)=1-0.3
P(not getting merit scholarships)=0.7
The probability that student not get the merit scholarship is 70%.
b)
P(getting at least one of two scholarships)=P(M or A)=P(M∪A)
P(getting at least one of two scholarships)=P(M)+P(A)-P(M∩A)
P(getting at least one of two scholarships)=0.3+0.6-0.08
P(getting at least one of two scholarships)=0.9-0.08
P(getting at least one of two scholarships)=0.82
The probability that student gets at least one of two scholarships is 82%.
Answer:
Step-by-step explanation:
We want to find the rational number which is equal to 
.
Let 
....eqn(1)
Multiply both sides by 10
.....eqn (2)
Subtract eqn (1) from eqn (2)
Divide both sides by 9.
Let
x-------> the number of churros sold
we know that
-----> inequality that represent the situation
Solve for x
Divide by 
both sides
therefore
<u>the answer is</u>
The minimum number of churros that must be sold is 
The common denominator is 18
Answer:
5 min
Step-by-step explanation:
I think its 17- 2ft (which was already dug)
then 15÷3 which is 5
