Answer:
2/15
Step-by-step explanation:
Step one:
given data
sample space
1 elephant,
4 bears,
3 cats, and
2 dogs.
sample size= 1+4+3+2= 10
Required:
By selecting without replacement, the probability that she chooses a bear both times
Step two:
the first event= Pr(bear)= 4/10= 2/5
the second event, the sample size is now 9 and the number of bears is now 3
Pr(bear)= 3/9= 1/3
Hence, the probability that she chooses a bear both times
= 2/5*1/3
=2/15

An Irrational Number is a real number that cannot be written as a simple fraction.
Let's rewrite the system of equations:
y = three over four times x squared minus 3
y = (3/4) x ^ 2 - 3
y = negative three over four times x squared plus 3
y = (-3/4) x ^ 2 + 3
The system of equations is:
y = (3/4) x ^ 2 - 3
y = (-3/4) x ^ 2 + 3
The solutions are:
(-2, 0)
(2, 0)
Answer:
See attached image
Answer:
The lines are parallel only if:
x-1 = 63
or, x = 64 degrees
This is a conjunction, where y is sitting in between 2 numbers. Y is less than 4, so all numbers less than 4 are included, but at the same time it has to be greater than -1. So y is then between -1 and +4 on a number line. Putting it into an inequality, it's -1<y<4
