Expected value = Sum of Probability * Cost of each ice cream.
Expected value
= 50%* $1.20 + 30%* $2.00 + 2<span>0%* $3.50
</span>
= 0.50* $1.20 + 0.30* $2.00 + 0.2<span>0* $3.50
</span>
= $1.90
Expected value of the cost of one ice cream = $1.90
5/3 means (5 over 3 since I can't do fractions on this)
5/3-3/3=___
5-3=2 first you do the numerators
You keep the denominator the same since both denominators are 3
Then you put it together and get 2/3 and since 2/3 can't be reduced, 2/3 is the answer
The correct answer is 8
Because
In triangle ORB
OR=(OB^2-RB^2)^1/2
OR=(17^2-15^2)^1/2
OR=(289-225)^1/2
OR=(64)^1/2
OR=8
RB=AB/2 so I kept its value 15 and ^1/2 refers to square root
Answer:
r = -2
Step-by-step explanation:
−88=11(r−6)
-88 = 11r -66
11r =-88+66
11r = -22
r = -2
Answer:
48
Step-by-step explanation:
Plug in 16 to the function:
f(16)=1/3(4-16)^2
=1/3(-12)^2
=144(1/3)
=48
