If we denote a cystic fibrosis gene with a c and a​ disease-free gene with a C​ (since the disease is​ recessive), then only a c

c person will actually have the disease. Such persons would ordinarily die before parenting​ children, but a child can also inherit the disease from two Cc parents​ (who themselves are healthy—that ​is, have no symptoms but are​ "carriers" of the​ disease). Suppose a child is born to one cystic fibrosis carrier parent and one​ non-carrier parent. Find the probability that that the child will be a carrier.

The length of pathway is 10 inches on map.

Step-by-step explanation:

Given,

Total distance = 350 miles

According to map,

1 inch = 35 miles

Let, x be the number of inches on map.

Therefore, using proportion;

Inch : mile :: inch : mile

1:35::x:350\\

Product of mean = Product of extreme

35*x=350*1\\35x=350\\

Dividing both sides by 35;

\frac{35x}{35}=\frac{350}{35}\\x=10

The length of pathway is 10 inches on map.

K= 8. If you look at the pattern each x value is multiplied by 8 to give you the y value. You could also solve it by:

40=k5
40/5=k
8=k

you could do this with any of the x or y values and still end up with 8.
