Answer:

19.0%

Step-by-step explanation:

The probability that a student in the sample data is enrolled in painting Given that the student is female is a conditional probability and can be defined as :

Let,

F = Female ; P = painting

P(Painting Given female) = P(P|F) = (PnF) / F

From the table :

(PnF) = 16

F = 84

Hence,

P(P|F) = 16 / 84 = 0.19047 = 0.19047 * 100%

P(P|F) = 19.0%

Find the distance of ST given, S ;-2,4) and T (4,1)

Angelina_Jolie [31]

You have to use the distance formula which is:

Distance = √(x2 - x1)^2 + (y2 - y1)^2

Using the coordinates given.

D = √(4 - (-2)^2 + (1 - 4)^2

D = √(6)^2 + (-3)^2

D = √36 + 9

D = √45

D = √9 × 5

D = 3√5

Challenge! A. 13 B. 24 C. 6 D. 34

irga5000 [103]

Answer:

A. 13.

Step-by-step explanation:

x + 9 = 2(3x - 38)

X + 9 = 6X - 76

85 = 5x

x = 85/5

x = 17

So RS = 3(17) - 38

= 51 - 38

= 13
