Answer:

54.1%

Step-by-step explanation:

From the table, the total number of patients with type-B blood is given as 183. On the other hand, the number of males with type-B blood is given as 99. The percentage of patients with type-B blood who are males can be calculated as;

(the number of males with type-B blood/the total number of patients with type-B blood) * 100%;

( 99/183) * 100 = 54.1%

Therefore, the percentage of patients with type-B blood who are males is 54.1

What is the equation of a line that passes through the points (3, 6) and (8, 4)?

romanna [79]

Answer:

y = -2/5x +36/5 . . . . . slope-intercept form

2x +5y = 36 . . . . . . . . standard form

Step-by-step explanation:

You can use the 2-point form of the equation of a line to find it.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (4 -6)/(8 -3)(x -3) +6

y = -2/5(x -3) +6

y = -2/5x +36/5 . . . . slope-intercept form

2x +5y = 36 . . . . . . . standard form

What is the value of -3(7+5) +9(2)? 0-6 -2. O 14 0 22

Ratling [72]

-3(7+5) 3
———-

7+5= 12

-3 x 12 = 36

3x3 = 9

36/9

+9 (2) = 18

36 = 4 wholes

18 + 4 = 22

Of course, I’m not 100% sure if it’s correct. But it’s what I got.
