Answer:
a) t = 2.8982
b) 1.826
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 18 - 1 = 17
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 17 degrees of freedom(y-axis) and a confidence level of ![1 - \frac{1 - 0.99}{2} = 0.995([tex]t_{.995}](https://tex.z-dn.net/?f=1%20-%20%5Cfrac%7B1%20-%200.99%7D%7B2%7D%20%3D%200.995%28%5Btex%5Dt_%7B.995%7D)
). So we have T = 2.8982. This is the answer for a.
The margin of error is:
M = T*s = 2.8982*0.63 = 1.826
In which s is the standard deviation of the sample.
Answer: 2(x- 6)(x - 1)
Step-by-step explanation:
To find the equavalent version of 3% as a decimal, we can divide by 100.
3 / 100 = 0.03
Therefore, the answer is 0.03.
Best of Luck!
The picture is not clear... the Question has got cut at the sides .... please take the picture properly and the post the Question again... please
No they are not unequal... i. e. the two wires A and B are equal .
of A = of B
=> 
× A = B
=> 1 × A = B
=> A = B
<em>:</em><em>.</em> The length of A = the length of B .
HOPE IT HELPS
PLEASE MARK ME BRAINLIEST ☺️
