There are four blood types, and not all are equally likely to be in blood banks. In a certain blood bank, 49% of donations are Type O blood, 27% of donations are Type A blood, 20% of donations are Type B blood, and 4% of donations are Type AB blood. A person with Type B blood can safely receive blood transfusions of Type O and Type B blood. What is the probability that the 4th donation selected at random can be safely used in a blood transfusion on someone with Type B blood?

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
