Answer:
Step-by-step explanation:
1) Let the random time variable, X = 45min; mean, ∪ = 30min; standard deviation, α = 15min
By comparing P(0 ≤ Z ≤ 30)
P(Z ≤ X - ∪/α) = P(Z ≤ 45 - 30/15) = P( Z ≤ 1)
Using Table
P(0 ≤ Z ≤ 1) = 0.3413
P(Z > 1) = (0.5 - 0.3413) = 0.1537
∴ P(Z > 45) = 0.1537
2) By compering (0 ≤ Z ≤ 15) ( that is 4:15pm)
P(Z ≤ 15 - 30/15) = P(Z ≤ -1)
Using Table
P(-1 ≤ Z ≤ 0) = 0.3413
P(Z < 1) = (0.5 - 0.3413) = 0.1587
∴ P(Z < 15) = 0.1587
3) By comparing P(0 ≤ Z ≤ 60) (that is for 5:00pm)
P(Z ≤ 60 - 30/15) = P(Z ≤ 2)
Using Table
P(0 ≤ Z ≤ 1) = 0.4772
P(Z > 1) = (0.5 - 0.4772) = 0.0228
∴ P(Z > 60) = 0.0228
Compare the two sets of numbers with a ratio. 1 can for 24 servings is to 1/2 can for x servings.
x= # servings from 1/2 can
1/24= (1/2)/x
cross multiply
1 * x= 24 * 1/2
x= 24/2
x= 12 servings
ANSWER: She can make 12 servings from 1/2 can of juice.
Hope this helps! :)
<h2>39/6 = 6.5</h2><h2 /><h2>6 hours 30 minutes</h2>
Answer: 3n-6
Step-by-step explanation: You have to use the distributive property. 3 times n is 3n and 3 times -2 is -6.
