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

Which graph below solves the following system of equations correctly? y = three over four times x squared minus 3 y = negative t
Zielflug [23.3K]
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)

Which of the following inequalities represents a number y that is less than 4 but greater than –1
yarga [219]
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
