Answer:
843.6736
Step-by-step explanation:
1% = 7.8848
7.8848 x 7 = 55.1936
788.48 + 55.1936 = 843.6736
Answer:
32/3
Step-by-step explanation:
First you need to understand the slope-intercept form
y = mx +b
m = the slope of the line
b = the y-axis intercept
y and x represent the coordinates of a point on the line
So for the equation that you listed we know that the slope, m , is (3/4). We also know a given point on the line. therefore we also have a y value (1/3) and a x value (4).
So plug in the numbers:
(1/3)=(3/4)*4 + b
So to find the equation of this line we must solve for b
Multiply (3/4) and 4 to get 3
(1/3) = 3 + b
Now subtract 3 from both sides in order to isolate b
-2 2/3 = b or -8/3 = b
Now rewrite the equation with the y-intercept, b.
y = (3/4)x - (8/3)
From the wording I am assuming you are given a list of equations to chose from. It is possible that the some of all of the equations are listed in standard form. In that case, we need to find the equation:
Ax + By = C
To do that we simply take the slope intercept equation and manipulate it algebraically
y = (3/4)x - (8/3) First subtract (3/4)x from both sides
-(3/4)x + y = -(8/3) This is technically standard form but we can clean it up a bit by multiplying both sides of the equation by -4.
So -4 * -(3/4)x = 3x
-4 *y = -4y
-4 *-(8/3) = 32/3
So 3x - 4y = 32/3
I hope this helps
Answer:
30
It's thirty because median is the middle of all numbers, and thirty is the middle of all numbers.
Answer:
The sample size is 
Step-by-step explanation:
From the question we are told that
The margin of error is E = 0.03
The sample proportion is 
From the question we are told the confidence level is 95% , hence the level of significance is
=> 
Generally from the normal distribution table the critical value of 
is
Generally the sample size is mathematically represented as
![n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p )](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%7D%7BE%7D%20%5D%5E2%20%2A%20%5C%5E%20p%20%281%20-%20%5C%5E%20p%20%29%20)
=> ![n = [\frac{1.96}{0.03} ]^2 *0.12 (1 - 0.12 )](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7B1.96%7D%7B0.03%7D%20%5D%5E2%20%2A0.12%20%281%20-%200.12%20%29%20)
