Let A be the number of Adult tickets and S, the Students'
A+ S = 273, but we know that S=2.A
Then A + 2A = 273 ; 3A =273; A =273/3 =91
So 91 tickets were sod to Adults & 182 Tickets to Students
The first one 1.001, because the zeros in front make it smaller
Answer:
The mean is 40.35 and the standard deviation is 0.13.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a certain type of olivine assembly, the silicon dioxide (SiO2) content (in weight percent) in a randomly chosen rock has mean 40.35 and standard deviation 0.4.
Sample of 10:
By the Central Limit Theorem, the mean is 40.35, and the standard deviation is 
The mean is 40.35 and the standard deviation is 0.13.
1200 milligrams because 400 times 3 would equal a full 24 hours
Answer:
27: 29.93 Seconds
28: 28 ° Fahrenheit
Step-by-step explanation:
Number #27:
Given:
#1 Lap = 14.76 seconds
#2 Lap = 15.17 seconds
Steps:
1. Use the algorithm method.

Number #28:
Given:
Wind Chill Temperature: - 18 ° F
Actual Temperature: 10 ° F
Steps:
1. Subtract 18 from 10.
Answer: - 28 ° degrees fahrenheit
Note: Whenever there is a negative sign next to a temperature, it means it's below freezing as the below freezing temperature is 0 ° Fahrenheit. This also means subtraction. In this case, you would subtract the negative amount from the positive amount creating an equation, that equation represents the degrees in fahrenheit:
10 - 18
The result should be -28.
This also means that the difference between both temperatures is 28 degrees. Wind chill creates a feeling of higher temperatures even though the actual temperature in the atmosphere was 10 ° F in this specific land structure.
