Answer:
Divide 120 by 100 (Because 120 is 100% of the animals). You get 1.2. Multiply 20% by 1.2 and get 24.

Answer: 0.0174
Step-by-step explanation:
Given : 
Let x be the random variable that represents the weight of the drumsticks.
We assume that the weight of the drumsticks is normally distributed.
Now, the z-score for x=2.23 ,
Using z-value table , we have
P-value =P(x≥2.23)=P(z≥2.11)=1-P(z<2.11)=1-0.9825708
=0.0174292≈0.0174 [Rounded nearest 4 decimal places]
Hence, the probability of the stick's weight being 2.23 oz or greater = 0.0174
Recall that to compute for the new amount of the original sum at a compound interest is
A(t) = P(1 + r/n)^(nt)
where P is the original amount, r is the interest rate, n is the number of times P is compounded each year, and t is the number of year.
With this, the total amount owed by Sam in five full years becomes [(120)(1 + 0.30/12)^60 ]. The total interest is the difference between the original amount owed and the amount that needs to be paid over time. Thus, total interest is [(120)(1 + 0.30/12)^60 ] - 120 = 407.97.
Therefore, the total interest is $407.97<span>.</span>
Answer:
7 to the right
Step-by-step explanation:
Ratio of classes A, B, C = 4 : 6 : 5, respectively
4 + 6 + 5 = 15
So, class A represents 4/15 of the TOTAL population
Class B represents 6/15 of the TOTAL population
Class C represents 5/15 of the TOTAL population
So, weighted average of 3 groups combined = (4/15)(65) + (6/15)(80) + (5/15)(77)
= 260/15 + 480/15 + 385/15
= 1125/15
= 75
