You decide to record the hair colors of people leaving a lecture at your school. What is the probability that the next person who leaves the lecture will have brown hair? Express your answer as a simplified fraction or a decimal rounded to four decimal places. Blonde Red Brown Black Gray 29 30 38 49 49

38/195 or 0.1949

Step-by-step explanation:

The data of the distribution of hair colors of people in the lecture in question is provided bellow.

The probability that the next person who leaves the lecture will have brown hair is determined as the number of brown-haired people divided by the number of people in class.

The probability is 38/195 or 0.1949.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16
