Answer:
0.005 `; 0.00499 ;
No, because np < 10 ;
2000
Step-by-step explanation:
Given that:
Number of samples , n = 100
Proportion, p = x / n
p = 1 / 200
= 0.005
p = μ
Standard deviation of sample proportion :
σp = sqrt((p(1 - p)) / n)
σp = sqrt((0.005(1 - 0.005)) / 200)
σp = sqrt((0.005(0.995)) / 200)
σp = sqrt(0.004975 / 200)
σp = sqrt(0.000024875)
σp = 0.0049874
σp = 0.00499
np = 100 * 0.005 = 0.5
n(1 - p) = 100(1-0.05) = 95
Smallest value of n for which sampling distribution is approximately normal
np ≥ 10
0.005n ≥ 10
To obtain the smallest value of n,
0.005n = 10
n = 10 / 0.005
n = 2000
Answer:
Y = -4X + 5
Step-by-step explanation:
X is the slope, If you cover X, you can see that Y = 5

Answer:
Step-by-step explanation:
The slope-intercept form is 
, where m is the slope of the line and c is where the line crosses the 
-axis.
To calculate 
we can use the formula 
where 
is the difference in between two points and 
is the difference between 
.
Information we can get from the graph given: 
. Since 
is the point at which the line crosses the -axis.
To find let's get two points from the graph.
Point 1: 
Point 2: 
Now use the equation .
.
Now we have and , let's put them back into the general equation.
Answer: measure angle E= 88
