Answer:
a
Step-by-step explanation:
the other angles do not open past an L shaped to be larger than 90, so c and d are out. For choice b, the b corner doesn't make an L shape either so it is not 90.
Answer:
Check my explanation
Step-by-step explanation:
1. x=-7y
2(-7y)-8y=22
-14y-8y=22
-22y=22
y=-1;x=7, I used subtitution because that process was easier.
2. x=3+y
7(3+y)-y=-3
21+7y-y=-3
21+6y=-3
6y=-24
y=-4; x=-1, I used subtitution because that process was easier.
3. x=1 and y=1, I used elimination because that process was easier.
4. x-3=4x-9
-3x=-6
x=3; y=0, I used subsitution because that process was easier.
The correct option is a. Poisson.
The distribution used to describe the number of events that occur when a given average number of events is expected is the Poisson distribution.
<h3>What is Poisson distribution?</h3>
The Poisson is a distribution of probabilities used in statistics to indicate number of times times an occurrence is likely to happen over a certain time period.
Some key features regarding the Poisson distribution are-
- It is, in other words, a count distribution. Poisson distributions are frequently used to analyze independent events that happen at a constant rate during a specified time frame.
- It was named after Siméon Denis Poisson, a French mathematician.
- A Poisson is a discrete function, which means that the variables can only take values from a (possibly endless) list.
- To put it another way, the variable cannot accept all values in either continuous range.
- The variable in the Poisson distribution could only accept whole values (0, 1, 2, 3, etc.), no fractions or decimals.

Using the pythagorean theorem
Base×Base + Perpendicular×Perpendicular = Hypotenuse× Hypotenuse
or B^2+P^2=H^2
B=root H^2 -P^2
Here hypotenuse =50 and Perpendicular = 15
therefore
root(50×50-15×15)
=root(2500-225)
=root(2275)
=47.69
=47.7 (approximately)
Option D is your answer.
36=2*2*3*3=2²*3²
60=2*2*3*5=2²*3*5
LCM(36,60)=2*2*3*3*5=2²*3²*5=180
