Based on the venn diagram of siblings, the probability of having a brother and sister is c. 0.33.
<h3>What is the probability of brother and sister?</h3>
The probability of having a brother and sister can be found as:
= Number of those with brother and sister / Total number of people in poll
Solving gives:
= 10 / (8 + 10 + 5 + 7)
= 10 / 30
= 0.33
In conclusion, the probability of having a brother and sister is 0.33.

Answer:
79°
Step-by-step explanation:
since this figure goes around completely, the sum would be 360°
1 and 3 are equal, so you would multiply 101 by 2
101 × 2 = 202
subtract 202 from 360
360 - 202 = 158
4 and 2 are equal, so divide 158 by 2
158 ÷ 2 = 79
so angle 4 = 79°
Answer:
Step-by-step explanation:
The diagonal of any square with side length 
is equal to 
. Since the side length of the square is 10, the diagonal must be 
.
To support and prove this:
The diagonal creates two 45-45-90 triangles, with the diagonal being the hypotenuse of both of these triangles. The Pythagorean Theorem states that in any triangle, the sum of the squares of both legs is equal to the square of the hypotenuse (
).
Call the diagonal 
. In these two triangles, both legs are equal to 10 (the side lengths of the square), and the hypotenuse is the diagonal. Thus, we have:
