Find the hypotenuse of a right triangle that has a 13cm leg and a height of 7cm
12345 [234]

Answer:

14.76 cm

Step-by-step explanation:

Use the pythagorean theorem:

a² + b² = c²

Plug in the side lengths and solve for c:

7² + 13² = c²

49 + 169 = c²

218 = c²

14.76 = c

So, the hypotenuse is approximately 14.76 cm

10. A cab company charges a flat rate of $2 plus an additional $0.50 for every mile traveled.
zzz [600]
a.
f = total cab fare
m = distance travelled

f = 2 + 0.50m

b.
7.50 = 2 + 0.50m

c.
7.50 = 2 + 0.50m
7.50 - 2 = 0.50m
5.50 = 0.50m
5.50/0.50 = m
m = 11
 Sara travelled 11 miles.

d.
f = 2 + 0.50m
f = 2 + 0.50 x 10
f = 2 + 5
f = 7

When the cab fare is over $7.00 on the holidays, $1 is discounted off the fare.

e. 
Yes, Lupe traveled more than 10 miles. (refer to calculations used in c.)

A human gene carries a certain disease from the mother to the child with a probability rate of 70%. suppose a female carrier of
Sergeeva-Olga [200]
The probability of at least one child inheriting the disease can be given by
<em>P</em>(<em>X</em> ≥ 1) = 1 - <em>P</em>(<em>X</em> = 0).  This is because the only choice other than at least one child inheriting the disease is that no children get it.
Since there is a 70% or 0.7 chance that each child will inherit it, there is a 30% or 0.3 chance that they will not.  This gives us
1 - <em>P</em>(<em>X</em> = 0) = 1 - (0.3)(0.3)(0.3) = 1 - 0.027 = 0.973
There is a 97.3% chance that at least one of the children will get the disease from their mother.
