She made a mistake when she subtracted x1 from x2.
Step-by-step explanation:
Step 1 :
a)
The formula used by Lorena to calculate the slope between 2 points is correct
So the statement given in option 1 is not the reason for her mistake
Step 2:
b)
She has taken the fourth and fifth point and correctly used the x and y co ordinates to calculate the slope
Hence the statement in second option is not true
Step 3:
c)
While calculating the slope the denominator is -2 - (-4) . This gives 2 as the answer. But she has made a mistake in this subtraction giving -6 as the answer.
Hence she has made a mistake in subtracting x1 from x2 and this statement is true
Step 4:
d)
She has not made any mistake in subtracting y1 from y2. Hence this statement is not true

Answer:
Die: 16. 2/3%
Coin: 50%
Step-by-step explanation:
Well rolling a 4 on a 6 sided die is 1/6.
To make that a percent we first make it a decimal.
1 ÷ 6 = .16666 repeating
To make this a percent we move the decimal place 2 times to the right.
16.2/3%
The chance of flipping a heads on a fair sided coin is 50% because there are two sides with a 50/50 chance of being either.
<em>Thus,</em>
<em>for rolling a 4 on a 6 sided die there is a 16.2/3% chance and a 50% for flipping a heads on a 2 sided coin.</em>

Explanation:
We can rewrite the expression:
√8×√20
using the following rule for radicals:
√a⋅√b=√a⋅b
√8⋅√20⇒√8⋅20⇒√160
Now, we can use this rule for radicals to simplify the radical:
√a⋅b=√a⋅√b
√160⇒√16⋅10⇒√16⋅√10⇒4√10
