Answer:
57.1%
Step-by-step explanation:
We know that a coin has only two sides, heads or tails. Therefore if of the 84 times, 36 times he fell in heads, the other times he fell in tails.
84 - 36 = 48 times fell in tails.
Therefore to calculate the percentage that fell in tails, it would be the ratio between the number of times it fell in tails and the total number of experiments:
48/84 = 0.571, and that is 57.1%
Which means that 57.1% of the times the coin was thrown fell into tails.
Answer:
"As the x-values go to positive infinity, the function's values go to positive infinity."
Step-by-step explanation:
End-Behavior of a fucntion is basically what happens to the function when x goes to positive infinity and when x goes to negative infinity.
In this function, we can say:
- as we move to the right (x increases), the value of the function (y-value) increases towards positive infinity.
- Also,
- as we move to the left (x decreases), the value of the function (y-value) decreases towards negative infinity.
From the answer choices, we take the last one -- "As the x-values go to positive infinity, the function's values go to positive infinity."
* Note, this is a cubic function

Answer:
Length = 6
Width = 3/2
Step-by-step explanation:
You can choose to go about this question in lots of different ways, but this is how i did it. I drew a diagram of the rectangle and labeled it: the height/length as x and the width as x/4 (they told us the width is a quarter of the length). They also told us that the area is 9 square units.
We know that length x width = area
So: length x width = 9
I'm gonna bring in the variables i used in the diagram, so:
x 
= 9
Keep solving:
= 9
Times both sides by 4:
= 36
Square root both sides for x:
<em>* remember that when you square root, its possible to have a positive or negative version of the value</em>
x = ±6
Since its impossible to have a negative length, we can say that x = 6.
X was just the variable we gave to the length of the rectangle, so now we know the length is 6. If you needed to find width as well, you can do 6/4, which simplifies to 3/2.
To double-check
- 6 x 3/2 should equal 9, since length x width = area
which it is, so we're correct!
Hope that helped : )
