Answer: D
Step-by-step explanation: because I got the same question and got it right
228/12 = 19. To check, turn it into multiplication, by doing 19 * 12, which equals 228.
Hope this helps! ☺♥
Answer: f) None of the above
= ( 5.283, 5.917)
Therefore at 90% confidence interval (a,b) = ( 5.283, 5.917)
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 = 5.6ft
Standard deviation r = 1.0ft
Number of samples n = 27
Confidence interval = 90%
z(at 90% confidence) = 1.645
Substituting the values we have;
5.6+/-1.645(1.0/√27)
5.6+/-1.645(0.192)
5.6+/-0.317 ft
= ( 5.283, 5.917)
Therefore at 90% confidence interval (a,b) = ( 5.283, 5.917)
Answer:
y=2x-2
Step-by-step explanation:
find the slope (m)
m=y2-y1/x2-x1
m=4-(-2)/3-0
m=4+2/3-0
m=6/3
m=2
y-y1=m(x-x1)
y-(-2)=2(x-0)
y+2=2x
y=2x-2
3 thousands (the 4 is in the ten thousands place)
2 hundreds
1 tens
9 ones
