Answer:
Step-by-step explanation:
<h3>Table 1</h3>
- x- values change 1 to 4
- y- values change inconsistently and repeat at -2
This is <u>not</u> a linear function
<h3>Table 2</h3>
- x- values change 1 to 4
- y- values change consistently, with common difference of -2
<u>This is a linear function</u>
<h3>Table 3</h3>
- x- values change 1 to 4
- y- values change inconsistently, the difference is not common
This is <u>not</u> a linear function
<h3>Table 4</h3>
- x- values change 1 to 4
- y- values change inconsistently, the difference is not common
This is <u>not</u> a linear function
She originally started with 23.
We can tell this by working the equation backwards. Since she has 5 left and she had just given half to her brother, we know she had 10 a moment ago.
Before that, Mary had eaten a cookie. So we add 1 to the total and now have 11.
Before eating that cookie, she has given half to her sister, which would give her 22.
And before giving half to her sister, she had eaten the first one, which would give us 23 to start with.
You have a 1 in 50 chance (ie A)
Explanation:
Let's start with the first bag. In it sits 5 numbers. So, you have a 1 in 5 chance that the number picked will be yours.
Now, let's consider the second bag. You have 10 different numbers and only one of yours may be picked. Hence, you have a 1 in 10 chance that yours will get picked.
Since we want them simultaneously, we will need to multiply the two probabilities together, yielding a 1 in 50 chance.
Answer:
2
Step-by-step explanation:
i got 20/8 from multiplying same with 1/2
20/8 - 1/2 = 2
