Answer:
- 4x + 36
Step-by-step explanation:
(
- 6)² = (
- 6)(
- 6)
Each term in the second factor is multiplied by each term in the firs t factor, that is
(
- 6) - 6(
- 6)
Distribute both parenthesis
=
- 2x - 2x + 36 ← collect like terms
=
- 4x + 36
Answer: yes

Answer: 0.3413
Step-by-step explanation:
Given: an American household generates an average of 28 pounds of newspaper for garbage or recycling. Assume the standard deviation is 2 pounds.
Let
.
Let x be the random variable that denotes the amount of newspaper for garbage generated by each household each month.
If the data conforms to a normal distribution and a household is selected at random, the probability of its generating between 28 and 30 pounds per month is about

Hence, the required probability is 0.3413.
Answer:
18 square units
Step-by-step explanation:
To find the area of a rectangle, we just need the length and height.
3 vertices of a rectangle are given, which is enough here to figure out the length (x-axis distance) and the height (y-axis distance).
From (0,0) origin to (3,0) would be 3 - 0 = 3 units in the x-axis. That is length:
Length = 3 units
Now, a point is given (0,6), that is in the y-axis. This is from origin. So, the height is:
6 - 0 = 6 units
Height = 6
Now, the area would be:
Area = Length * Height
Area = 3 * 6
Area = 18 square units
Answer:
I believe the answer is B
Step-by-step explanation:
The answer is b, because it is linear and x and y have a proportional relationship with x increasing by 2 and y increasing by 4. So the slope is 2/4 or 1/2 making it a proportional relationship.
