Answer:
None of the above
Step-by-step explanation:
Given that Jaquelyn was tardy on Monday, there is a 12 percent chance she will be late on Tuesday as well.
What is the Probability?
How likely it is that a stated event would occur is assessed using probability. The event would have a probability of 1 if it happened with certainty. The probability of an occurrence would be zero if it were absolutely guaranteed that it would not occur.
As getting late on Monday and Tuesday are independent events, their probabilities can be multiplied.
So the probability of getting late on Tuesday, given she was late to school on Monday = Probability of being late on Monday x Probability of she being late on Monday and she is late on Tuesday 60% of the time.
= 0.2 x 0.6
= 0.12
Thus the approximate probability that Jaquelyn will be late on Tuesday, given she was late to school on Monday will be 0.12

Given a quadratic equation in standard form
The discriminant D
tells the types of roots the equation has.
In this case, we have
Then, the discriminant of this quadratic equation will be
Finally, the value of discriminat is 49 and as he discriminant is greater than zero then this quadratic equation has 2 different real solutions.
The perimeter is 106 ft.
To find the perimeter, just add all of the side lengths together. And since this is an irregular shape, I would split it into two different rectangles, find the perimeter of the two separate, then add them together.
Hope this helps! :)
Step 2 is divide the difference between the original number and the new number by the original number. you will get a decimal.
step 3 convert what you got from step 2 to a percent by multiplying it by 100 and adding %
