The probability would be 1/15.
The first draw, taking a gold coin is 3/10.
Since we don't replace it, we draw again, but a value less- 2/9.
We multiply that together and get 6/90, then simplify it :)<span />

brainly.com/question/9480049The lengths of the sides of the triangle are 16, 63, and 65.
a0 = 63
a1 = 65
_____
You have
.. a0² +16² = a1²
You want
.. a1 = a0 +2
so
.. a0² +256 = (a0 +2)² = a0² +4a0 +4 . . . . substitute and expand
.. 252 = 4a0 . . . . . . . . . subtract a0² +4
.. 63 = a0 . . . . . . . . . . . .divide by 4
.. a1 = 63 +2 = 65
Step-by-step explanation:
the answer is in the above image
Using the t-distribution, the 96% confidence interval is given as follows:
(18.96, 21.04).
<h3>What is a t-distribution confidence interval?</h3>
The confidence interval is:
In which:
- is the sample mean.
- s is the standard deviation for the sample.
The critical value, using a t-distribution calculator, for a two-tailed 96% confidence interval, with 100 - 1 = 99 df, is t = 2.0812.
The parameters are given as follows:
Hence the bounds of the interval are:
