Answer:
1067
Step-by-step explanation:
Given that:
Error (E) = 0.03
Confidence interval = 95% = 0.95
Sample size (n) = ((Zα/2) / Error)^2 * p(1 - p)
Since no assumption is given ; p = 0.5
α = 0.95
Z(1-α/2) = 1.96
(1.96 / 0.03)^2 * 0.5(1 - 0.5)
(65.333333)^2 * 0.5(0.5)
4268.4444 * 0.25
= 1067.1111
n = 1067
400% of a is 4a
4a/400a = 1/100=1%
Answer:
Unless that is a right triangle we cannot calculate an exact answer.
The third side has to be greater than 2 (because 19 -17 = 2) and must be less than 36 (because 19 + 17 = 36)

Answer:
Step-by-step explanation:
Given:
We need to reduce the given matrix to reduced echelon form.
Solution:
Make zeroes in column 1 except the entry at row 1, column 1. As we can see all elements in column are already zero. Make zeroes in column 2 except the entry at row 2, column 2.
So, in reduce echelon form is
1. If you add all, it equals to 9/6 divide by 3 then it equals to 3/2. Each square equals to 1/6 because if you divide 3/2 into 9 parts, one part would be equal to 1/6.
