You made one? Oml.. You could of just texted me. It's B
Answer:
1
The correct option is C
2
The correct option is C
3
The correct option is A
4
The correct option is B
Step-by-step explanation:
From the question we are told that
The population mean is 
The standard deviation is 
The sample size is 
The sample mean is 
Generally
The null hypothesis is 
The alternative hypothesis is 
Given that the null hypothesis is true then the distribution of sample means
, from a sample size of 36 is mathematically represented as

=> 
According to the Central Limit Theorem the test stated in the question is approximately normally distributed if the sample size is sufficiently large
so given that the sample size is large n = 36
Then the test is normally distributed and hence the standard deviation is 15
Generally the standard error of mean is mathematically represented as

=> 
=> 
Generally the approximate probability of observing a sample mean of 105.1 or more is mathematically represented as

=> 
From the z-table (reference calculator dot net )

So

5 pizza / 6 student = 'Z' pizza / 1 student
Cross-multiply the proportion:
5 pizza-student = 6 Z pizza-student
Divide each side of the equation by 6 pizza-student :
5/6 = Z
Each student gets 5/6 of 1 pizza.
It's not so complicated. Cut each pizza into 6 slices,
and each student gets 5 slices.
That's the same as (83 and 1/3) percent of a pizza.
Answer:
18000
Step-by-step explanation:
Answer:
z = 92
x = 11
Step-by-step explanation:
From the figure,
13x - 55 = 88 (Opposite angles made by two straight lines are equal)
13x = 88 + 55
13x = 143
x = 143/13
x = 11
Again,
88 + z = 180 (Sum of angles of a straight line)
z = 180 - 88
z = 92
