It can be deduced that the probability of having 4 or more correct guesses will be 0.0296.
<h3>How to calculate the probability</h3>
From the given information, the null hypothesis is p = 1/7 and the alternate hypothesis is p>1/7. In this case, the mind reader gets a 4 out of 9 chances.
In order to test the hypothesis, simulations for 10000 cases were run with a probability of the correct answer being 1/7.
In this case, the p-value is the probability of correct answers that are greater than 4, assuming the null hypothesis is true. Here the p-value is 0.0296.
Also, the significance level to reject the hypothesis is less than 0.01. Since p > 0.01, we then fail to reject the hypothesis. Therefore the null hypothesis stands and Joao is not a mind reader.

Answer:
ab+xy−5
Step-by-step explanation:
yx+ab−5 = xy+ab+−5
Simplify-
ab+xy−5
This equation does not have a solution. You can see this through the work below.
4m-4=4m
-4m -4m
-4≠0
There is no solution because 0 does not equal -4.
Answer:
25 in; C

Hey!
There probably is a reason she is deleting. You could contact her or ask some help elsewhere.
Anyway! I'm trying to get this in fast. (Remember the Pythagorean Theorem?) That will be very useful here since it is a right triangle.
<u>L² + L² = H² (or H² - L² = L²):</u>
In that case, we'll use the second one because our Hypotenuse is given.
We can substitute each value of the numbers:
65² - 60² = L²
Evaluating:
4225 - 3600 = 625
√625 = 25 inches
Thusly, the third side would be 
<em>Also note we could have simplified into a Pythagorean Triple. This method is a simpler more basic method for learning the concept.</em>
Hope this helps!
