Answer:
Yes, this is a Binomial distribution, and the number of trials is 10.
Step-by-step explanation:
From the given information:
We are being told that ten students are chosen from a statistics class of 22 students.
If X represents the random variable for the number of students who got an "A" in the class.
Then we have two possible outcomes;
Number of students that got an "A" = (Success)
Number of students that did not get an "A" = (Failure)
Thus, this is a Binomial distribution because it consists of two outcomes, and the number of trials is 10.

Find
The sum of angles in a semi-circle is 180 degrees.
So:
This gives:
Hence, the equation is:
Answer:
x=2±16i
Step-by-step explanation:
1.) Using the PEMDAS distribute the using the FOIL method
2.) Distribute the -16 to ()
3.) Add the -25 to the equation
=0
4.) Since this isn't factor-able, you must use the quadratic formula,
and distrubute the numbers
a=-16 b=64 and c=-89
5.) Simplify the radical by finding the factors of -18688 that has a perfect root as one of the factors (which is -256 and 73).
6.)Simplify the fraction
7.) Your two roots are:
{2}(+ or -)16i\sqrt{73}
5 10 15 20 25 30 35 40 45 50 55 60 65 70 75
24 divided by 80= 0.3
24/30 there were 30 questions on the test and he got 24 right
