Answer:
There are ways of slowing the rate at which we add greenhouse gases to the atmosphere that actually save money. These are familiar ideas like switching to more efficient cars, heating and air conditioning systems, light bulbs, and appliances; and putting better insulation in homes and buildings.
Step-by-step explanation:
Answer:
c) Statistically significant results that are the opposite to what was hypothesized are likely the result of a Type II error.
Step-by-step explanation:
Which statement is true?
statistically significant results are results of a null hypothesis that is true. while
Type 2 error is the error that occur when one fails to reject a null hypothesis that is wrong.
therefore, Statistically significant results that are the opposite to what was hypothesized, is a type 2 error, because it is false.
c) Statistically significant results that are the opposite to what was hypothesized are likely the result of a Type II error.
Answer:
A. 4.5 ft
B. 4 ft
C. 1 ft
Step-by-step explanation:
If you pretend that h is replacing y and d is replacing x and you would graph the equation, then you would get a parabola that opens down.
You would need to find the vertex of the parabola. The ordered pairs would be (d, h) instead of the normal (x, y).
A. The maximum height will be the h value of the vertex
B. Let h = 0 and solve the equation for d. That will give you distance from the stump that the frog landed.
C. The distance from the log at the maximum height is the d value of the vertex
So, that is what is needed to be done.
Without me going thru all the work, the vertex is (1, 4.5) and the solutions to the equation when h = 0 are 4, -2 (discard -2 since a distance cannot be negative)
So the answer to A is 4.5 ft.
The answer to B is 4ft.
The answer to C is 1 ft.
Now, can you find the vertex on your own and can you solve the equation when h = 0? I hope so. OK?
The base of the triangle ABC is 12 units.
Step-by-step explanation:
Step 1; First we need to identify which side is the base of the triangle. In this given triangle side CB is the base. So we plot points C and B on the graph. Coordinates for C are (-4, -3) and for B are (8, -3). We need to find the distance between the 2 edges of the triangle.
Step 2; To find the distance of CB, we use the formula;
Distance = √ (x2 - x1)² + (y2 - y1)².
Distance between C (-4, -3) and B (8, -3) where C is (x1, y1) and B is (x2, y2).
Distance = √(8 - (-4))² + (-3 -(-3))² = √12² + 0² = √12² = 12 units.
Similarly, triangle ABC's height equals 10 units.
