Coin resulted in heads
Student is selected at random from a class of six boys and sixteen girls.

Probability:

72.73% probability of selecting a girl, given the flip resulted inheads
The answer is x= 5/2 or -1
Answer:
x^2/400 + x^2/625
(x-0)^2/400) +(y-0^2/625)
x^2=400
X=sqrt. 400
x = 20
y^2=625
y = sqrt. 625
y= 25
a^2-c^2=b^2
sqrt 400-625 = c
20-25=c
The correct answer is c=-5
(-5,0)
(5,0)
Step-by-step explanation:
Answer:
$2.55
Step-by-step explanation:
If you Multiply $85 by 0.03 you get your answer because you have to turn the 3% into a decimal which you have to move the decimal two places to the left.
