Answer:

3/4
4/13
7/26
2/13
5.52

Step-by-step explanation:

(a)

Probability (A heart or a black card) = 13 + 26 / 52
Probability (A heart or a black card) = 39/52
Probability (A heart or a black card) = 3/4

(b)

Probability (A heart or a jack) = 13 + 3 / 52
Probability (A heart or a jack) = 16/52
Probability (A heart or a jack) = 4/13

(c)

Probability (A heart and the ace of clubs) = 13 + 1 / 52
Probability (A heart and the ace of clubs) = 14/52
Probability (A heart and the ace of clubs) = 7/26

(d)

Probability (A 9 or a jack) = 4 + 4 / 52
Probability (A 9 or a jack) = 8/52
Probability (A 9 or a jack) = 2/13

(e)

Probability (The 9 of hearts or a jack) = 1 + 4 / 52
Probability (The 9 of hearts or a jack) = 5/52

Given three points A(-7, 1), B(m, 6) and P(-1, n). If the point P divides AB internally in the ratio of 3: 2, find the values of

vesna_86 [32]

Answer:

m = 3 , n = 4

Step-by-step explanation:

Using Section Formula.

$If \ the \ line \ segment \ AB \ where \ A = (x _1, y_1) \ and \ B = (x_2, y_2) \ divided \ by \ P =(x , y) \ in \ the \ ratio \ a : b,\\\\Then \ the \ points \ of \ P \ \\\\x = \frac{ax_2 + bx_1}{a+b} \ and \ y = \frac{ay_2 + by_1}{a+b}$

$Here (x_1 , y_ 1 ) = ( -7 , 1 ) \ and \ (x_ 2 , y _ 2 ) = (m , 6)\\\\ratio\ a:b = 3 : 2\\\\Therefore, P (x, y) \\\\x = \frac{3m + (2\times -7)}{5} \ \ \ \ \ \ \ \ \ \ \ [ \ x = -1 \ ] \\\\-1 = \frac{3m - 14}{5}\\\\- 5 = 3m - 14\\\\-5 + 14 = 3m\\\\9 = 3m \\\\m = 3$

$y =\frac{3\times 6 + 2 \times 1}{5}\\\\n = \frac{18 + 2}{5} = \frac{20}{5} = 4$
