Answer:
(-3,2)
Step-by-step explanation:
Answer: No, the normal curve cannot be used.
Step-by-step explanation:
The theorem of the Normal approximation states that if X is B(n,p) then for large n X is N(np, np(1-p)).
The accuracy of this approximation is good
i. for n > [10/p(1-p)]
ii. p is close to 1/2
Hence given p= 4% = 0.04,
q = 1 - 0.04 = 0.96
Let N = [10/p(1-p)]
We find N = 10/p(1-p) = 10/(0.04× 0.96)
N ~= 260
Since n < 260 and p < 0.5
The approximation is not a good one
Answer:
4√6^3
Step-by-step explanation:
X/5+9=4
Subtract each side by 9
X/5=-5
Multiply each side by 5
X=-25
Answer:
Option c. (x, y) → (y , x)
Step-by-step explanation:
we know that
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places
Remember that each point of a reflected image is the same distance from the line of reflection as the corresponding point of the original figure
so
The rule of the reflection across the line y=x is
(x,y) → (y,x)
