There are 4 chocolate chip cookies and 12 oatmeal cookies in a jar. If you reach in and randomly choose 2 cookies without replac
ing the first, what is the probability that both will be chocolate chip? 6
1 answer:
Answer:
A
Step-by-step explanation:
So there are 4 chocolate chips and 12 oatmeal. In total, there are 16 cookies.
The probability of selecting a chocolate chip when you reach in for the first time will be 4/16 or 1/4.
The second time, you reach in, however, there would be one less chocolate chip cookie because you would've pulled one out previously. Thus, the probability is now 3/15 or 1/5.
So, the probability of pulling a chocolate chip cookie consecutively is:
Our answer is A :)

Answer:
The lines are perpendicular
Step-by-step explanation:
we have
isolate the variable y
----> equation A
The slope of the line A is
-----> equation B
The slope of the line B is
Remember that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
In this problem
The slopes of line A and line B are opposite reciprocal
therefore
The lines are perpendicular
Answer:
Option (b)
Step-by-step explanation:
Let the points represented by the given table lie on a line.
And the equation of the line is,
y = mx + b
Where m = slope of the line
b = y-intercept
Let the points lying on the line are (0, -2) and (3, -3)
Slope of the line 'm' =
m =
m =
m = -
y-intercept 'b' = (-2)
Equation of the line is,
y =
This equation matches with equation given in option (b).
Option (b) will be the answer.
