A​ person's blood type is denoted with the letters​ A, B, and​ O, and the symbols​ + and - . The blood type​ A+ is read as A pos
postnew [5]

Answer:

(a) O+ to A+

O+:A+=90:45

O+:A+=18:9

O+:A+=2:1

(b) AB- : AB+

AB-:AB+ = 6:4

AB-:AB+ = 3:2

AB-:AB+ = 12:8

(c): B+ to total

B+ : Total = 20 : 195

B+ : Total = 4 : 39

B+ : Total = 40 : 390

Step-by-step explanation:

Given

A+ = 45       B+ = 20        AB+ =6        O+=90

A-=21       B-=0          AB-=4          O-=9

Total = 195

See attachment

Required

Solving (a): O+ to A+

We have:

A+ = 45

O+=90

So, the ratio is:

O+:A+=90:45 ---- first comparison

Divide by 5

O+:A+=90/5:45/5

O+:A+=18:9 ---- Second comparison

Divide by 45

O+:A+=90/45:45/45

O+:A+=2:1 ---- Third comparison

Solving (b): AB- to AB+

We have:

AB+ =6

AB-=4

So, the ratio is:

AB-:AB+ = 6:4 ---- first comparison

Divide by 2

AB-:AB+ = 6/2:4/2

AB-:AB+ = 3:2 ---- Second comparison

Multiply by 2

AB-:AB+ = 6*2:4*2

AB-:AB+ = 12:8 ---- Third comparison

Solving (c): B+ to total

We have:

B+ = 20

Total = 195

So, the ratio is:

B+ : Total = 20 : 195 ---- first comparison

Divide by 5

B+ : Total = 20/5 : 195/5

B+ : Total = 4 : 39 ---- Second comparison

Multiply by 2

B+ : Total = 20*2 : 195*2

B+ : Total = 40 : 390 ---- Third comparison

A textbook search committee is considering 13 books for possible adoption. The committee has decided to select 3 of the 13 for f
laiz [17]

Number of ways in which the 3 can be selected from 13  = 286

Step-by-step explanation:

Step 1:

Number of books considered by the textbook search committee = 13

Number of books selected from this 13 = 3

We need to determine number of ways in which the 3 can be selected from the 13

Step 2 :

The order of the 3 books selected does not matter. So,

Number of ways in which the 3 books can be selected from 13 books =  C(13,3) = \frac{13!}{10! . 3!}

                                                                                             =\frac{ 13 . 12 .11  . 10!}{10! . 3! }

                                                                                             =\frac{1716}{6} = 286

Step 3 :

Answer :

Number of ways in which the 3 can be selected from 13  = 286
