Answer:
The number of cake for order is 15 cakes .
Step-by-step explanation:
Given as :
Total number of people to attend the dance = x = 60
The number of slices each person will eat = A = 2 slices
The number of slices per cake = y = 8 slices
Let The number of cake for order = z
<u>Now, According to question</u>
Total slices of cake required for 60 people when each people eat 2 slices = total number of people × number of slices each person will eat
i.e Total slices of cake required for 60 people when each people eat 2 slices = x × A
Or, Total slices of cake required for 60 people when each people eat 2 slices = 60 × 2 slices
Or,Total slices of cake required for 60 people when each people eat 2 slices = 120 slices
<u>Again</u>
∵ number of slices per cake = 8
∴ The number of cake for order =
Or, z =
i.e z =
∴ z = 15 cakes
So,The number of cake for order = z = 15 cakes
Hence,The number of cake for order is 15 cakes . Answer
Answer:
C)A is 15.95% ,B is 11.85%
Step-by-step explanation:
We know that the expected value in probability distribution is given as
Lets X is the expected value then
For stock A
X=0.25 x 0.45+0.14 x 0.25+0.04 x 0.3
X=0.1595
So the expected return for A is 15.95%
For stock 9
X=0.3 x 0.3+0.09 x 0.25+0.02 x 0.3
X=0.1185
So the expected return for B is 11.85%
So our option C will be the answer of that problem.
