Answer:
the slope is -1/4
Step-by-step explanation:
the change in y over the change in x from point (-2,-2) to (2,-3) is how to find the slope
y1-y2/x1-x2 = m
-2--3/-2-2 = -1/4
Answer:
25%
Step-by-step explanation:
customer paid = 9492
less vat (13%) .net =8400
discount =16%==marked price = 8400X 100/84==10,000
profit on sale =5% . cost :=8000
% on cost (2000/ 8000) X100 =25%
Answer:
0.0623 ± ( 2.056 )( 0.0224 ) can be used to compute a 95% confidence interval for the slope of the population regression line of y on x
Step-by-step explanation:
Given the data in the question;
sample size n = 28
slope of the least squares regression line of y on x or sample estimate = 0.0623
standard error = 0.0224
95% confidence interval
level of significance ∝ = 1 - 95% = 1 - 0.95 = 0.05
degree of freedom df = n - 2 = 28 - 2 = 26
∴ the equation will be;
⇒ sample estimate ± ( t-test) ( standard error )
⇒ sample estimate ± (
) ( standard error )
⇒ sample estimate ± (
) ( standard error )
⇒ sample estimate ± (
) ( standard error )
{ from t table; (
) = 2.055529 = 2.056
so we substitute
⇒ 0.0623 ± ( 2.056 )( 0.0224 )
Therefore, 0.0623 ± ( 2.056 )( 0.0224 ) can be used to compute a 95% confidence interval for the slope of the population regression line of y on x
X% of 150 = 108
x/100 * 150 = 108
1.5x = 108
x =108 / 1.5
x = 72
Therefore 72% of 150 is 108
Hope this helps.
You have to divide both by common factor, in this case it's 12
So 72/60 = 6/5
Thus, 6/5 is the simplest form.
