Answer:
Step-by-step explanation:
Slope-intercept equation of a line is,
y = mx + b
Here, m = Slope of the line
b = y-intercept
If m = -6 and b = 3,
Equation of the line will be,
y = -6x + 3
Input - output values got the graph of this line,
x -1 0 1 2
y 9 3 -3 -9
Now by plotting these points we can draw the line on graph.
Answer:
2510000 INR
Step-by-step explanation:
Given
Required
The amount that will be withdrawn in India
We have:
Multiply both sides by the savings
So, we have:
<em>Hence, the amount that will b withdrawn is: 2510000 INR </em>
Answer:
It is not reasonable that the state education department claims the percentage for the entire state is 73%.
Step-by-step explanation:
We are given that 191 of the 288 high school students surveyed at a local school said they went outside more during school hours as elementary school students than they do now as high school students.
Firstly, the pivotal quantity for finding the confidence interval for the population proportion is given by;
P.Q. = ~ N(0,1)
where, = sample proportion of high school students who went outside more during school hours as elementary school students than they do now as high school students =
= 0.66
n = sample of high school students = 288
p = population percentage for the entire state
<em> Here for constructing a 90% confidence interval we have used a One-sample z-test for proportions. </em>
<em> </em>
The margin of error is given by;
M.E. =
=
M.E. = 0.056 or 5.6%
So, the confidence interval so formed =
= []
= [0.604, 0.716]
Since the above interval does not include 0.73 or the population proportion of 73% falls outside the above interval. So, it is not reasonable that the state education department claims the percentage for the entire state is 73%.
