Answer:
In the given table that gives data on the people's height and hair color, we are asked to get the probability that the person is taller than 180 centimeters and has black hair. There are 29 people with that the person is taller than 180 centimeters and has black hair. hence the probability is 0.116
Step-by-step explanation:
Been a while but I'm gonna try..! Okay!
For the Focus use the vertex to find it. (9/2 , 0)
For the directrix I believe it is. x = -9/2
Y α 1/x
y = k/x Where k is the constant of proportionality.
xy = k Cross Multiplying.
k = xy
Recall y= -8 when x = -9
k = -9 * -8 = 72
Finding y when x = 4.
k = xy
72 = 4y Divide both sides by 4.
y = 72/4 = 18.
y = 18.
12/8=
6/4=
3/2
Your answer in simplest form would be 3/2
Hello,
Answer A
Let's the width of the rectangle
2a-5 its length
Teh half perimeter is 80/2=40
a+2a-5=40 ==>3a=45==>a=15 and 2a-5=30-5=25
