Answer:
b. 1.15
Step-by-step explanation:
The z statistics is given by:
In which X is the found proportion, p is the expected proportion, and s, which is the standard error is 
Out of 53 teachers who replied to the survey, 13 claim they are satisfied with their job.
This means that 
She find that the proportion of satisfied teachers nationally is 18.4%.
This means that 
Standard error:
p = 0.184, n = 53.
So
Z-statistic:
The correct answer is:
b. 1.15
Answer:
-1/5
Step-by-step explanation:
slope formula:
m = y₂ - y₁ / x₂ - x₁
Two points are given:
(-5, -5) (5, -7)
m = -7 - (-5) / 5 - (-5)
m = -2 / 10
m = -1/5
Do you have a picture of the graph? They formula put into y=mx+b is y=4/3+2
so the y intercept is 2 and the slope will be going upwards :)
Answer:
slope: -3
y-intercept: 3
y = -3x +3
Step-by-step explanation:
Hint: Use the Desmos Graphing Caculator for liner equaions!
Answer:
36,060,024 ways
Step-by-step explanation:
To choose the winner in this case, the order is very important because it determines who is chosen first out of the seventy-nine customers whose names were entered for the draw.
The above supports the reason Permutation will be used instead of Combination.
The total number of ways is given by:
⁷⁹P₄ = 79!/(79-4)!
= 79!/75!
= [79 x 78 x 77 x 76 x75!]/75!
= 79 x 78 x 77 x 76
= 36,060,024 ways
This implies that there are 36,060,024 ways the Bean Coffee Shop could choose the winners.
