Answer:
The margin of error is 
Step-by-step explanation:
From the question we are told that
The number of student is 
The highest amount is 
$200
The lowest amount is 
$75
The sample mean is 
&140
The Standard deviation of this set is mathematically evaluated as
Substituting values
The margin of error (ME) is mathematically evaluated as
Where 
is the critical value for 
i.e the significance level
From the critical value table this is 
So
Answer:
Compare the y-intercepts and slopes of the linear functions f(x) and g(x) and choose the answer that best describes them.
x f(x)
0 1
2 9
4 17
g(x) = 3x + 1
A) The slope of f(x) is less than the slope of g(x). The y-intercept of f(x) is equal to the y-intercept of g(x).
B) The slope of f(x) is less than the slope of g(x). The y-intercept of f(x) is greater than the y-intercept of g(x).
C) The slope of f(x) is greater than the slope of g(x). The y-intercept of f(x) is equal to the y-intercept of g(x).
D) The slope of f(x) is greater than the slope of g(x). The y-intercept of f(x) is greater than the y-intercept of g(x).
Step-by-step explanation:
Answer:
46.5 cm
Step-by-step explanation:
63 ÷ 2= 31.5 + 15 = 46.5
Answer: 23
Explanation: simplify using PEMDAS so solve parentheses, then solve the exponent, multiply the second number by 4, and then add, then subtract.
Hope this helps!
