Length of shorter piece is 13 ft
Length of longer piece is 61 - 13 => 48 ft
Answer:
1/2 is the slope of the line
Step-by-step explanation:
To find slope, use the following equation
slope (m) = (y₂ - y₁)/(x₂ - x₁)
First, set each coordinate. Let:
(x₁ , y₁) = (8 , -6)
(x₂ , y₂) = (4 , -8)
Plug in the corresponding numbers for the corresponding variables.
m = (y₂ - y₁)/(x₂ - x₁)
m = (-8 - (-6))/(4 - 8)
Simplify. Note that two negative signs would result in a positive sign.
m = (-8 + 6)/(4 - 8)
Combine like terms.
m = -2/-4
Simplify. Divide common factors from both the numerator and denominator.
m = (-2/-4)/(-2/-2) = 1/2
1/2 is the slope of the line

Biased or Unbiased:
Take 20 packages off the top of the load of packages being shipped by a truck and measure the amount of damage expected to the whole truckload.
Answer: It is a biased way of taking sample. Because the top layer of packages has less weight resting on it and may have less damage. Therefore, the given statement is biased and based on these 20 packages of the top of the load, we can not make a decision about how much damage a truckload contains.
(−4) − 6

-4 - 6
<u>Subtract the numbers: </u>
- 4 - 6 = 10
= −4 −6
= −4 + −6
<u>Answer = −10</u>
Hope that helps!!! : )
