Answer:
258
Step-by-step explanation:
Set up the two equations needed (x is the adult tickets and y is the student tickets)
x+y=372
6x+2y=1776
Solve by elimination
-2(x+y=372)
=-2x-2y=-744
Cancel like figures:
-2x-2y=-744
6x+2y=1776
= 4x=1032
x=258
Answer:
15
Step-by-step explanation:
Given:
Volume of Cone= 5
Solution:
Formula:
Volume of Cone =
Volume of Cylinder=
We can say that
Volume of Cone = Volume of Cylinder
Volume of cylinder = 3 Volume of Cone
Now Substituting given data we get
Volume of Cylinder= 35
Volume of Cylinder= 15
√(4×18)= √72 or √36√2= 6√2 simplified
Answer:
a: 11.12%
b: about 2.5%
c: about 2.5%
Step-by-step explanation:
For this situation:
n = 1500
p = 0.35
q = 1 - p = 0.65
a: Find: P(p < 0.335)
See attached photo 1 for the solution
b. Find P(p > 0.37)
Since it says that σ = 0.01, and it's asking for the percent of the proportion larger than 0.37, they are asking for the percent of the proportion that is 2 standard deviations higher than the mean. Using the 68-95-99.7 rule, we have a total of 5% of data that is more than 2 standard deviations away, but that is on both sides of the mean. Divide that in half to get the total above 0.37. So there should be about 5%/2 = 2.5% of the proportions.
c: Find P(p < 0.33)
0.33 is 2 standard deviations below the mean, so the percentage is 2.5% for similar reasons for part b
