Answer:
Step-by-step explanation:Write as two points in terms of: (number of people, cost in $)
�
(15,120) and (25,200)
�
Find the equation of the line using:
�
m = (y2 – y1) / (x2 – x1) and y = mx + b
�
Equation:
�
Y = 8x
�
plug in x = 40
�
y = 8(40) = 320
�
A party of 40 people will cost $320.00.
�
Slope:
�
m = 8 $/person
�
For every person that attends the party, the caterer’s bill increases by $120.00.
�
y-intercept: 0
�
(0,0)
�
This tells us that if no one attends the party, the caterer’s bill will be $0.00. So the
�
caterer has no base cost they charge to caterer a party.

Answer:
An 99% confidence interval of the given proportion
(0.355 , 0.385)
Step-by-step explanation:
Given sample size n= 900
the number of successes in the sample is x=333
The proportion P = 
Q = 1-P =1 - 0.37 = 0.63
<u>Confidence interval</u>:-
99% of confidence interval zα = 2.93
(0.37 - 0.015 , 0.37 + 0.015)
(0.355 , 0.385)
<u>Conclusion</u>:-
<u>An 99% Confidence interval (0.355 , 0.385)</u>
ANSWER
P=8,Q=16
EXPLANATION
We can see from the table that both pattern P and Q have an initial value of 24.
Pattern P is reducing by a constant difference of 4.
The next value for pattern P is
12-4=8.
Also pattern Q is reducing by a constant value of 2.
The next value for pattern Q is,
18-2=16
Answer:
A
Step-by-step explanation:
The x- coordinate of each point ( the domain ) maps to exactly 1 unique y- coordinate ( the range).
This means the situation given represents a function → A
