The probability that a randomly selected student from the class has brown eyes , given they are male
Step-by-step explanation:
<u>Explanation</u>:-
Given data
Brown Blue Hazel Green
Females 13 4 6 9
Males 10 2 9 12
<em>Let 'B' be the event of brown eyes </em>
<em>Total number of males n(M) = 33</em>
Let B/M be the event of randomly selected student from the class has brown eyes given they are male
<em>The probability that a randomly selected student from the class has brown eyes , given they are male</em>
<em></em>
<em></em>
<em>From table the brown eyes from males = 10</em>
<u>Final answer</u>:-
The probability that a randomly selected student from the class has brown eyes , given they are male
Answer:
A Quadratic Equation can have upto 2 roots maximum. So,if one of the roots is a Real number, there are following two possibilities:
1) The other root is also a real number, but a different number
2) Its a repeated root, so the other root is the same number.
The other root cannot be a complex number as its not possible for one root to be real and other to be complex. Either no root will be complex or both will be complex roots.
Following are 3 possibilities for the roots of a quadratic equation:
- 2 Real and Distinct roots
- 2 Real and Equal roots
- 2 Complex roots
Answer:
D
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y) → (- y, x)
A translation of 3 units up → + 3 in the y- direction, that is add 3 to the y- coordinate, hence
(x, y) → (- y, x) → (- y, x+ 3) → D

A coefficent is the number in front of the letter and a constant is just a number
Answer:
The slope is 2.
Step-by-step explanation:
The formula for slope is m = (y2-y1)/(x2-x1)
If we choose the points (0,2) and (1,4) we can plug these into our slope equation.
(4 - 2) / (1 - 0) = 2/1 = 2
