Answer:
$550+/-$20.79
= ( $529.21, $570.79)
Therefore, the 95% confidence interval (a,b) = ( $529.21, $570.79)
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 x = $550
Standard deviation r = $75
Number of samples n = 50
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
$550+/-1.96($75/√50)
$550+/-1.96($10.60660171779)
$550+/-$20.7889393668
$550+/-$20.79
= ( $529.21, $570.79)
Therefore, the 95% confidence interval (a,b) = ( $529.21, $570.79)
-4 times -2 equals 8.
8 times -1 equals -8.
Therefore, the point on your number line that is on -8 is your answer!
Answer:
3/4
Step-by-step explanation:
Old x: 72 New x: 8
To get 6 (old y) from 72 (old x), multiply by 1/12
To get New Y, multiply 8 * 1/12 = 3/4
The sequence rule is <span>f(n+1)=1.5(n), then
</span>
for n=0, f(1)=0;
for n=1, f(2)=1.5;
for n=2, f(3)=3;
for n=3, f(4)=4.5, and so on.
You receive the arithmetic sequence 0,1.5,3,4.5,....
