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

DIA [1.3K]

Answer:

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)

Let u = <-9, 4>, v = <8, -5>. Find u - v. <br> URGENT

Pie

To subtract vectors, you simply have to subtract correspondent coordinates.

So, if you have

$u = \langle u_1,\ u_2,\ldots u_n\rangle ,\quad v = \langle v_1,\ v_2,\ldots v_n\rangle$

the subtraction is simply

$u-v = \langle u_1-v_1,\ u_2-v_2,\ldots u_n-v_n\rangle$

So, in your case, we have

$\langle-9,4\rangle-\langle 8,-5\rangle=\langle -9-8, 4+5\rangle=\langle -17,9\rangle$
