Answer:
60m
Step-by-step explanation:
8x+100 with x representing the number of classes attended. For Ms.Wiggins, the equation would be 8(18)+100. You would multiple 8 x 18 getting 144+100. You add 144+100 to get $244 for Ms.Wiggins.
Answer: = ( 0.411, 0.409)
Therefore at 95% confidence interval (a,b) = (0.411, 0.409)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean gain x = 0.41
Standard deviation r = 0.016
Number of samples n = 1000
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
0.41+/-1.96(0.016/√1000)
0.41+/-1.96(0.000506)
0.41+/-0.00099
0.41+/-0.001
= ( 0.411, 0.409)
Therefore at 95% confidence interval (a,b) = (0.411, 0.409)
Answer:
C, 3
Step-by-step explanation:
By creating a best line of fit you can get the sets of points (16,50) and (12,40)
Using these to find the slope we can get 
-10/-4 is 2.5 The best approximation would be C, because if you round it up to the nearest number you would get 3.
