5(2j+3+j)
= 5(2j) + 5(3) + 5(j) we distribute 5 to all of the expression
= 10j + 15 + 5j connect like terms j
= 15j + 15
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:
22 feet
Step-by-step explanation:
Given
- In blue print,dimensions of rectangular balcony are, length(l)=1.75inch and breadth(b)=1inch
- The actual length(L)=7 feet
To find the actual perimeter, we need the breadth of balcony(B)
The ratio of length to breadth in blue print must be equal to the ratio of actual length to breadth
⇒
Therefore Breadth actually=4 feet
⇒Perimeter
Therefore perimeter of rectangular balcony= 22 feet
