Answer:
B
Step-by-step explanation:
If the numerator is one, the denominator is going to be the same value as a normal positve interger.
Answer:
c=√2
Step-by-step explanation:
Use the Pythagorean theorem:
- c=√2
Answer: 21
Step-by-step explanation:
Given : The scores on the midterm exam are normally distributed with
Let X be random variable that represents the score of the students.
z-score: 
For x=82
For x=90
Now, the probability of the students in the class receive a score between 82 and 90 ( by using standard normal distribution table ) :-
Now ,the number of students expected to receive a score between 82 and 90 are :-
Hence, 21 students are expected to receive a score between 82 and 90 .
The measure of ∠ROU is 94°. That is a central angle, which means that the arc it intercepts also measures 94°. Because ∠SOT is vertical to ∠ROU it is also a 94° angle with a 94° intercepted arc. The other 2 angles, ∠SOR and ∠TOU are vertical and have the same measure, both the angles and their intercepted arcs. Those measures will split the difference of 360-94-94, which is 172. 172/2 is 86. That means that those arcs also measure 86. Arc SRT is the addition of arc SR, RU. and UT, which are 86+94+86, respectively, which add up to 266. Second choice down.
Answer:
f'(x) = -f(x) = 9xy² - 6x²y + 5x³
Step-by-step explanation:
f(x) = –9xy² + 6x²y – 5x³
additive inverse: f'(x) = -f(x) = 9xy² - 6x²y + 5x³
f(x) + f'(x) = f(x) -f(x) = (–9xy² + 6x²y – 5x³) + (9xy² - 6x²y + 5x³) = 0
