Answer:
5^3 = 125
Step-by-step explanation:
The caret(^) is a symbol used to indicate exponentiation. So, you simplify 5 raised to the 3rd power, which is 125.
Answer:
Mean = 16.5
Variance = 35.55
Step-by-step explanation:
<u> x P(x) x. P(x) x² x². P(x)</u>
6 0.10 0.6 36 3.6
12 0.35 4.2 144 50.4
18 0.25 4.5 324 81
<u> 24 0.30 7.2 576 172.8</u>
∑x P (x) 16.5 ∑x² P (x) 307.8
The expected value of x E[X] gives the mean where X is the discrete random variable with the given probabilities.
Mean is given by E(X)= ∑x P (x) = 16.5
Similarly the variance is also calculated using the expected value of X and X².
Variance is given= E(X)²- [E(X)]²= 307.8- (16.5)²= 307.8-272.25 = 35.55
Answer:
Step-by-step explanation:
Yoga Fun's price is represented by 65+12c where c represents classes.
Yoga For All's price is represented by 15c where c represents classes.
We notice that for the prices to be equal, 65+12c must equal 15c. This means that we take the difference, which shows that 65 must equal 3c. We divide to determine we must take 21.666... classes for the prices to be equal.
Si is = PRT so your answer is 1500x5x4 which is = 30000
You could find a common denominator.2/6=8/24 5/8=15/24
