The line with slope of 1/3 passing through the point -2,5
Firdavs [7]

Step-by-step explanation:

Equation of line in slope point form is given as:

y - y_1 = m(x-x_1)  \\ y - 5 =  \frac{1}{3}(x + 2) \\ y - 5 =  \frac{1}{3} x +  \frac{2}{3}  \\ y = \frac{1}{3} x +  \frac{2}{3} + 5 \\ y = \frac{1}{3} x +  \frac{2 + 3 \times 5}{3} \\  \\  \red { \bold{y = \frac{1}{3} x +  \frac{17}{3} }}\\

A group of people were given a personality test to determine if they were Type A or Type B. The results are shown in the table b
amm1812

Answer:

Option A: P(Male or Type B) > P(Male | Type B)

Step-by-step explanation:

Total Female = 85 type A, 12 type B  ⇒ 97 Female.

Total Male = 65 type A, 38 type B   ⇒ 103 Male

Total type A = 65 + 85 = 150

Total type B = 12 + 38 = 50

total number of people = 97 + 103 = 200

Then the probability would be:

P(Male | Type B) = \frac{number of male in B}{total number of male}

                           = \frac{38}{103}

                           = 0.368

P(Male or Type B) = \frac{total number of male + (total number of people in B - total number of male in B)}{total number of male}

                              =  \frac{103 + (50 - 38)}{200}

                              = \frac{103 + 12}{200}

                              = \frac{115}{200}

                              = 0.575

 Hence, P(Male or Type B) > P(Male | Type B)
