Answer:
B. m∠A + m∠C = m∠B + m∠D
Step-by-step explanation:
To inscribe a quadrilateral in a circle, the sums of its opposite angles must be equal (each sum of its opposite angles equals 180 °)
Answer: The answer here is x=12.49
Step-by-step explanation:
The idea is tho remove the brackets on the right hand side by multiplying by 4.9
4.90= 10(x-12)
4.90=10x-120
x=12.49
Answer:
20%
Step-by-step explanation:
We are asked to find the proportion of of scores in a normal distribution between the mean (z = 0.00) and z = +0.52.
We will use normal distribution table to find area under normal distribution curve corresponding to given score as:
![P(0.00](https://tex.z-dn.net/?f=P%280.00%3Cz%3C0.52%29%3DP%28z%3C0.52%29-P%28z%3C0.00%29)
Using normal distribution table, we will get:
![P(0.00](https://tex.z-dn.net/?f=P%280.00%3Cz%3C0.52%29%3D0.69847%20-0.50000)
![P(0.00](https://tex.z-dn.net/?f=P%280.00%3Cz%3C0.52%29%3D0.19847)
![P(0.00](https://tex.z-dn.net/?f=P%280.00%3Cz%3C0.52%29%3D19.847%5C%25)
![P(0.00](https://tex.z-dn.net/?f=P%280.00%3Cz%3C0.52%29%5Capprox%2020%5C%25)
Therefore, approximately 20% of scores in a normal distribution between the given z-scores.
Answer:
3
Step-by-step explanation:
one whole divided by one-third is written as....
1 ÷ 1/3
Use KFC to simplify
Keep the first fraction or number, Flip the second fraction, and change it to multiplication...
so we have 1 * 3/1 which is 3/1 or just 3
* you can also read this as, how many thirds go into 1. 3 thirds will go into 1
