The answer is 12.5 because of 50/4= 12.5 per game
Answer:
a. Yes
See explanation below.
Step-by-step explanation:
Assuming that if the question is if we can use the normal approximation for the true proportion.
For this case we have n = 40 and p = 0.3 (probability of success)
We need to check some conditions:
1) Random sample : This condition is satisfied since the problem says that she randomly select 40 records
2)
3) 10% condition: the random sample is assumed to be less than 10% of the original population size (assumed)
The population proportion have the following distribution
So then as we can see the normal approximation for this case makes sense since we have all the 3 conditions satisfied so then the answer would be:
a. Yes
To find the perimeter of a square you would multiply the length of one side by 4, so you would now have:
(3x+4) * 4 = 76
Divide both sides by 4:
3x +4 = 19
Subtract 4 from both sides:
3x = 15
Divide both sides by 3:
x = 5
Answer:
Wonka bars=3 and Everlasting Gobstoppers=24
Step-by-step explanation:
let the wonka bars be X
and everlasting gobstoppers be Y
the objective is to
maximize 1.3x+3.2y=P
subject to constraints
natural sugar
4x+2y=60------1
sucrose
x+3y=75---------2
x>0, y>0
solving 1 and 2 simultaneously we have
4x+2y=60----1
x+3y=75------2
multiply equation 2 by 4 and equation 1 by 1 to eliminate x we have
4x+2y=60
4x+12y=300
-0-10y=-240
10y=240
y=240/10
y=24
put y=24 in equation 2 we have'
x+3y=75
x+3(24)=75
x+72=75
x=75-72
x=3
put x=3 and y=24 in the objective function we have
maximize 1.3x+3.2y=P
1.3(3)+3.2(24)=P
3.9+76.8=P
80.7=P
P=$80.9
