PLEASE HELP! a person with blood type o can donate red blood cells to anybody because type o blood is a universal blood type. About 44% of the US population has type o blood. University High held a blood drive where 50 students donated blood. Part A: what is the probability that exactly 25 of the students had type o blood?

part b: what is the probability that at least 25 of the students had type o blood?

thank you so much!

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
