Answer:
A or Out of the 352 eleventh graders at the school, 173 of them are girls
Step-by-step explanation:
cause i did it and your welcome to all the poor souls in
Sin < C = 63/65 so m < C = 75.75 degrees
and tan B = 16/63 so m <B = 14.25 degrees
m < C + m<B = 75.75 + 14.25 = 90 degrees
Therefore m < A = 180-90 = 90
therefore the triangle is right-angled.
The correct answer is D.
In order to solve for a function's inverse, you must start by switching the x and f(x) values. Then you solve for the new f(x). Once you have done that, you'll be left with the new function, which is the inverse of the original. See the work below for how this one will be solved.
f(x) = 
----> Switch the x and f(x)
x = 
----> Now subtract the 5 from both sides.
x - 5 = 
---> Now square both sides.
= f(x) - 1 ----> Now add 1 to both sides.
+ 1 = f(x)
And now that you have something equaling f(x), you can change the order and match it up to answer D.
f(x) = + 1
Answer:
The statistical conclusion is:
a) Your results are significant; one's willingness to wear masks is not independent of one's age.
Step-by-step explanation:
From this experiment,
The null hypothesis is established as:
H 0 = one's willingness to wear masks is independent of one's age.
The alternate hypothesis is established as:
H 1 = one's willingness to wear masks is not independent of one's age.
In statistics, if the absolute value of the test statistic is greater than the critical value, we declare statistical significance and reject the null hypothesis.
Since the test statistic = 16.5, which is higher than the critical value of 7.82, this establishes statistical significance. Thus, the null hypothesis is rejected.
Therefore, the statistical conclusion is that one's willingness to wear masks is not independent of one's age.
Step-by-step explanation:
6 - 2x = 3
2x = 6 - 3
2x = 3
x = 3/ 2
Hope it will help :)
