Answer:
A square root of 11, 3.7, square root of 20, 4.8
Step-by-step explanation:
4.8
√20 = 4.47
3.7
√11 = 3.32
Answer:
The probability is 1
Step-by-step explanation:
Given
Number of flips = 8
Outcomes = 8 heads
Required
Probability of getting a head in the next row
This problem can be attributed to experimental probability and it'll be solved using experimental probability formula, which goes as follows;

Let
represents the probability of getting a head in the next row;



Hence, the probability of obtaining a head in the next flip is 1
Answer:
The angles are: 25°, 25°, 155° and 155°.
Step-by-step explanation:
1. By definition, the intersection of two lines forms four angles. Each opposite pairs of them are known as "Vertical angles" and they are congruent, which means than they have the same measure.
2. The sum of the four angles is 360°.
3. If the sum of the two angles is 50°, you can calculate the measure of each one of them by dividing 50° by 2:

4. To find each measure of the other two angles, you must subtract 360° and 50° and divide this by 2:

so the probability will be: p(red)=2652=0.5 or 50% as we could guess immediatelly.
