According to data from the state blood program, 40 percent of all individuals have group A blood. If six individuals give blood,
Serjik [45]

Answer: 0.27648

Step-by-step explanation:

Given : The proportion of all  individuals have group A blood : p=0.040

Total individuals give blood : n= 6

Let X be the number of individuals have group A blood.

Since all individual are independent of each other.

X\sim Bin(n=6, p=0.40)

Formula : P(X=x)=^nC_xp^x(1-p)^{n-x} , where n= sample size , p = probability of getting success in each trial.

The probability that exactly three of the individuals have group A blood. :

P(x=3)= ^6C_3(0.40)^3(1-0.4)^3\\\\= \dfrac{6!}{3!3!}\times(0.40)^3(0.60)^3\\\\=0.27648

The probability that exactly three of the individuals have group A blood. is 0.27648

Find the unit rate.<br> 48 cupcakes in 6 boxes=cupcakes per box
natka813 [3]

Answer: 8 cupcakes per box

Step-by-step explanation: "Per box" means in 1 box, so we can rewrite the given statement using fractions as

<em>48 cupcakes/6 boxes</em> = <em>__ cupcakes/1 box</em>.

To find out what goes in the blank, notice that we

have a 1 in the denominator of our second fraction.

So we want to find a fraction that is equivalent

to 48/6 that has a 1 in the denominator.

If we divide the numerator and denominator of 48/6 by 6,

we get the equivalent fraction 8/1 or <em>8 cupcakes/1 box</em>.

So now we have <em>8 cupcakes/1 box = __cupcakes/1 box</em>.

So an 8 must go in the blank which means that the unit rate

for 48 cupcakes in 6 boxes is <em>8 cupcakes per box</em>.

Step-by-step explanation:

3x+6 = 4x^2

4x^2 -3x -6 = 0

x = \frac{3+\sqrt{105} }{8}  , \frac{3-\sqrt{105} }{8}  x=1.655,-0.905
