Answer: y = - 0.4 x - 4.5
Step-by-step explanation:
Equation y=mx+b
m is the slope
x is *ANY* x coordinate
y is *ANY* y coordinate
b is y intercept or WHERE the point is on the Y AXIS
Lets look at the given:
Slope (m) is -2/5
Passes through point 15, -9/2
As you can see, the point goes through the Y axis at (-9/2)
Our equation is y = - 0.4 x - 4.5
A 98% confidence interval is found to be (32, 42). What is the margin of error?
A. 5
B. 4.9
C. 9.8.
D. 10
Answers
Answer:
A
Step-by-step explanation:
Just took the exam
Using confidence interval concepts, it is found that the margin of error is 5.
What is a confidence interval?A confidence interval (CI) is a range of estimates for an unknown parameter in frequentist statistics. A confidence interval has the format (a,b).
The margin of error is half the difference between the two bounds, that is:
M = ( b - a ) / 2
In this problem, the interval is (32, 42), hence, and the margin of error is:
M = ( 42 - 32 ) / 2 = 10 / 2 = 5
Therefore the margin of error is 5.

A The inequality 25m + 70 < 350 represents the fact that the student must save more than $11.20 each week to meet the goal.
B The inequality 25m + 70 < 350 represents the fact that the student must save more than $265 each week to meet the goal.
C The inequality 25m + 70 > 350 represents the fact that the student must save more than $265 each week to meet the goal.
D The inequality 25m + 70 > 350 represents the fact that the student must save more than $11.20 each week to meet the goal. ZEF 4
Answers
Answer:
A.) The inequality 25m + 70 < 350 represents the fact that the student must save more than $11.20 each week to meet the goal. I hope this helped u :)
Step-by-step explanation:
25 x 11.20 = 280
280+70=$350
but since the student wants to save more than $350 that's why it says the student must save MORE than $11.20 each week :)
Find a 95% confidence interval for the mean auditory response time for subjects with a visual response time of 200 ms. The 95% confidence interval for the mean auditory response time for subjects with a visual response time of 200 ms is:____.

Answer:
A = 125, B = 55, C = 125
Step-by-step explanation:
A line that is cut into two by a line has two angles that equal 180. So angle A + angle D is 180. Angle D = 55 so 180 - 55 = 125. You do the same for every angle but look at the line as being cut into two in different directions for angles a and b and angles c and d.

multiply first
1 2/5m - 6/25m - 3/5
multiply 1 2/5 only so the denominator is 25 as we can't simplify 6/25, it's so we can add them together, we can't add 3/5 tho bc it's a different term so there's no need to multiply that.

Hi,
The ratio of two numbers is 3 to 5.
Let x represent the constant of the proportionality
3x + 5x = 136
8x = 136 (divide both sides by 8)
x = 17
The numbers are:
3*17 = 51 and
5*17 = 85
