Answer: 22) A
<u>Step-by-step explanation:</u>
First, order doesn't matter so it is a Combination.
<em>In other words, it doesn't matter which person was chosen 1st, 2nd, 3rd, or 4th to bring food because they are all bringing "food".</em>
Next, If you are going to choose person to 4 people to bring food out of a total of 4 + 3 + 1 = 8 people, you get → ₈C₄
And you are going to choose 3 people to bring decorations out the remaining 8 - 4 = 4 people, you get → ₄C₃
And you are going to choose 1 person to be the host out of the remaining 4 - 3 = 1 person, you get → ₁C₁
"And" means multiplication so altogether you get ⇒ ₈C₄ × ₄C₃ × ₁C₁
Answer:
The measure of the red angle says 20 degrees
the other angle is 70 degrees
Step-by-step explanation:
Answer: First option is correct.
Step-by-step explanation:
Since we have given that
Total area of square inches = 400
The area of the large circle = 314
Now, we need to find the probability that Trisha will not get any points with one randomly thrown dart that lands somewhere inside the square,
Let E be the event the Trisha will get points .
so,
![P(E)=\frac{314}{400}](https://tex.z-dn.net/?f=P%28E%29%3D%5Cfrac%7B314%7D%7B400%7D)
As we know that
![P(E')=1-P(E)\\\\P(E')=1-\frac{314}{400}\\\\P(E')=\frac{400-314}{400}\\\\P(E')=\frac{86}{400}\\\\P(E')=0.215=0.22](https://tex.z-dn.net/?f=P%28E%27%29%3D1-P%28E%29%5C%5C%5C%5CP%28E%27%29%3D1-%5Cfrac%7B314%7D%7B400%7D%5C%5C%5C%5CP%28E%27%29%3D%5Cfrac%7B400-314%7D%7B400%7D%5C%5C%5C%5CP%28E%27%29%3D%5Cfrac%7B86%7D%7B400%7D%5C%5C%5C%5CP%28E%27%29%3D0.215%3D0.22)
So, Probability that Trisha will not get any points with one randomly thrown dart that lands somewhere inside the square = 0.22
So, First option is correct.
Hey there!!
Given:
... A=3B+7C
Subtracting 7C on both sides:
... A-7C=3B
Dividing by B on both sides:
... (A-7C)/3=B
<em>Hope my answer helps!</em>
the first answer is 59.2 and the second answer is 1.5
