Si una cepa de influenza tipo A se genera en la parte norte de México, hay 67% de posibilidades de que ésta se propague por la frontera sur de EU. A partir de los datos recabados en los últimos 30 años, se ha determinado que la probabilidad de que una cepa tipo A se genere en la parte norte de México en cualquier año dado es de 0.80.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

the square root of 16 is 4.

4*4 = 16
