Answer:
if sinx=3/5=P/H
using pythogoras thoeren find B
B²= H²-P²
B²= 25-9
B=4
Tanx = P/B= 3/4
3.
n(S)= 6
n(O) = 3 {1,3,5)
P(O) = n(O)/n(s)= 3/6=1/2

Answer:
The <em>p</em>-value of the test is 0.0512.
Step-by-step explanation:
The <em>p</em>-value of a test is well-defined as per the probability, [under the null hypothesis (H₀)], of attaining a result equivalent to or more extreme than what was the truly observed value of the test statistic.
In this case the output of the t-test_ind method from scipy module is provided as follows:
Output = (-1.99, 0.0512)
The first value within the parentheses is the test statistic value.
So the test statistic value is, -1.99.
And the second value within the parentheses is the <em>p</em>-value of the test.
So the <em>p</em>-value of the test is 0.0512.
Answer: 4:5
Explanation:
Steve earns 8 dollars an hour. His brother earns 10 dollars an hour.
The ratio is Steve:Brother, which is 8:10.
This can be treated the same was as a fraction and simplified, dividing both sides by 2, which becomes 4:5
There are 4 quarters in dollars. Keep that in mind.
Since Taylor is spending no more than 17 dollars, she probably only has 17 dollars. We already know that she has 8 dollars in bills, so we can subtract 8 dollars from 17 dollars because we need to find the amount of dollars in quarters.
The answer for that is 9 dollars. Since there are 4 quarters in the dollars, you need to multiply 9 by 4 to find the amount of quarters.
You can take the a out of both values. There are no other factorable parts of this expression. Your factored version would look something like this- a(5a-4b)
Hope that helped you out a bit nuzhat! ☺️
