So Marci's sore was 45 because every percent has to be out of 100 so to get it to 50 you divide by two so 90 / 2 = 45. And 45-39 = 6
Marci got 6 more correct then Donovan.
(4x−101)(2x+3)
Apply the distributive property by multiplying each term of 4x−101 by each term of 2x+3.
8x²+12x−202x−303
Combine 12x and −202x.
8x²−190x−303
First, use distributive property on the right half.
2 * 5 = 10
2 * 2n = 4n
4n - 9 = 10 + 4n
Add 9 to both sides
4n = 19 + 4n
Subtract 4n from both sides
0 = 19
But thats not true. Therefore, there is no solution.
The line of best fit is given by the equation y = 1.56x - 4.105

<h3><u>
Answer:</u></h3>
Hence, the probability of the complement of rolling a number less than 5 by using a six-sided die is:
1/3
<h3><u>
Step-by-step explanation:</u></h3>
Let A denote the event of rolling a number less than 5 in a six-sided die.
Now, we know that the Total outcomes are: 6
since, the sample space is given as: {1,2,3,4,5,6}
Also Number of favorable outcomes are: 4
since the numbers which are less than 5 are {1,2,3,4}
Now we have to find:

where P denotes the probability of an event and
denote the complement of event A.
We know that:

Now,

Hence,

Hence, the probability of the complement of rolling a number less than 5 by using a six-sided die is:
1/3
