I have no idea what piecewise functions are or how to solve them! Please explain how, thank you!
I'm willing to give up a lot of points to understand this, so please help me.
Answer:
A piece wise function is pretty easy
Think of it like as a lot of functions with inequalities.
So lets say for example
Your Going to a skate park that counts time
Up to 6 minutes costs $50
Over 6 and up to 15 minutes costs $80
Over 15 minutes costs $80 plus $5 per minute above 15 minutes
The function would look something like
H(t)={ $50 If T is less then Or equal to 6
$80 If T is greater then 6 AND T less then or equal to 15
$80+$5(T-15) If T is greater then 15 }
Just simplify the worded problems into inequalities
And then a question would be something like, you visit for 13 minutes, how much would you pay?
It‘d be $80 becuase the chart says, if T (13) is greater then 6 And less then or equal to 15, its be 80 dollars.

Johnny scored 8 out of 10 attempts, Ray scores 1 out of 2 attempts and David scored 12 out of 20 attempts
Which player has the greatest free throw ratio?
Answer:
Johnny
Step-by-step explanation:
If we convert it so everyone has denominators of 20 we get:
(These are still equal to what their scores before were)
Johnny: 16/20
Ray: 10/20
David: 12/20
Johnny has made the most free throw shots, therefore, they have done the best.
Hope this helps!

Answer:
Johnny has the greatest free throw
Step-by-step explanation:
Lets look at the 1/2 mark of each one
Johnnys half mark is 5/10 he has 8/10 so he’s ahead
Rays half mark is 1/2 he’s at 1/2 so he’s lower then johnny
Davids half mark is 10/20 he’s at 12/20 a little over
Davids= 6/10
Johnnys= 8/10
Rays= 5/10
JONHNNYS IS THE GREATEST

Consider the square with vertices at (3, 3), (−3, 3), (−3, −3) and (3, −3). How many points with integer coordinates lie strictly in the interior of this square?
Answer:
The number points with that lie strictly in the interior of the square are 25 points
Step-by-step explanation:
The vertices of the square are; , (3, 3), (-3, 3), (-3, -3) and (3, -3)
From the attached diagram of the square created with Microsoft Word, where one box is equal to one unit, the number of points with integer coordinates that lie strictly in the interior of the square are given by the number of intersecting grid lines
The number of points on the interior of the square = 25 points
The points includes;
(-2, 2), (-1, 2), (0, 2), (1, 2), (2, 2)
(-2, 1), (-1, 1), (0, 1), (1, 1), (2, 1)
(-2, 0), (-1, 0), (0, 0), (1, 0), (2, 0)
(-2, -1), (-1, -1), (0, -1), (1, -1), (2, -1)

The value of expression 2a ^ 2 + 2b ^ 2 - ab for a-2, b-lis (a) 2 (b) 8 (c) 6 (d) 10
Answer:
[tex]2a^2 + 2b^2 - ab[/tex] [tex]= 8[/tex]
Step-by-step explanation:
Given
[tex]2a^2 + 2b^2 - ab[/tex]
Required
Evaluate when [tex]a=2\ and\ b=1[/tex]
To do this, we simply substitute 2 for a and 1 for b in [tex]2a^2 + 2b^2 - ab[/tex]
[tex]2(2)^2 + 2(1)^2 - 2 * 1[/tex]
[tex]2*4 + 2*1 - 2 * 1[/tex]
[tex]8 + 2 - 2[/tex]
[tex]8[/tex]
Hence:
[tex]2a^2 + 2b^2 - ab[/tex] [tex]= 8[/tex]
when [tex]a=2\ and\ b=1[/tex]

URGENT ! what is the common difference of the arithmetic series 14+12+10+8
Explanation:
An arithmetic sequence has a common difference, meaning you use addition or subtraction to get from term to term, and each term in the sequence is an equal distance apart.
A geometric sequence has a common ratio, meaning that you use multiplication or division to get from term to term.
If you look at this sequence:
14-2 = 12
12-2 = 10
10-2 = 8
8 -2 = 4
etc.
Because you are subtracting 2 each time, 2 is the common difference, and the sequence is arithmetic.
A biologist wonders if the life span of bats will be affected by two new food sources from invasive species moving into an area. To conduct the experiment, the biologist needs three treatment groups: a group where the diet will not include invasive species (control), a group where the diet will include one invasive species (treatment group 1), and another group where the diet will include the other invasive species (treatment group 2). The biologist chooses the first cloud-free night and catches the first 18 bats that fly out of a cave, placing them into three equal groups of six bats. To decide the treatment for each group, the biologist places three slips of paper labeled control, treatment group 1, and treatment group 2 in a hat and randomly selects 2 slips of paper. The first piece of paper gives the treatment for the first group, the second piece of paper gives the treatment for the second group, and the remaining treatment is given to the third group.
Which component is missing from the biologist’s process?
a.The biologist did not use proper labeling on the pieces of paper.
b.The biologist did not use the appropriate number of treatment groups.
c.The biologist did not randomly assign the individual bats to the treatment groups.
d,The biologist did not randomly choose the weather on the night for bat capture.
Answer:
D
Step-by-step explanation:
Every factor, besides for the factor you are testing for, must be the same for all of the groups and must be randomly selected. Choosing bats from one clear night isn’t random because a cloud free night might effect which bats first fly out of the cave.
It’s like surveying the first few people who walk out of a movie theater and asking if they thought the movie was good. Most likely not because they left so early/quickly. This can skew the results from being completely random and won’t reflect the entire population as a whole accurately.
Also, note that for every other answer choice, they are correct.
A - The biologist did use proper labeling
B - There are enough treatment groups
C - He did randomly assign 6 for each group
Therefore, by process of elimination, it is D.
I hope this helps! :)
The component that is missing from the biologist's process is: c. The biologist did not randomly assign the each of the bats to the treatment groups.
Importance of Random Assignment of Subjects into GroupsWhen carrying out a research study where you have groups created that you want to study, differences between and within groups can be satisfactory ensured that they are not systematic when subjects are randomly assigned to groups.
Thus, it gives the researcher the confidence that groups are the same in terms of variables, and any differences can be confidently ascribed to experimental treatments.
Therefore, the component that is missing from the biologist's process is: c. The biologist did not randomly assign the each of the bats to the treatment groups.Learn more about random assignment on:

Find the input (x) of the function y = 3x - 7 if the output
(y) is 5.
Answer:
The input (x) = 4
Step-by-step explanation:
Since we know what the output (y) is, you can substitute it into the equation to get:
5 = 3x - 7
Then, solve for x, and you’ll get x = 4. The image below shows step-by-step on how to solve for x.

What is the distance of the point P(x,y) from y axis? Wht does this even mean?
Answer:
The x value
Step-by-step explanation:
Basically, the question is asking you to find the straight line distance from the y axis to a given point. The y-axis on a coordinate plane is the axis that goes up and down, and the x axis is the one that goes left and right. In a coordinate pair (x,y), x is how far left or right the point is and y is how far up or down it is. so the point (3,9) is three to the right and three up. (See screenshot)
So, the distance that (3,9) would be from the y-axis would be how far right it is, or x, which is 3!
if f(x) = 1/2 * x - 1 what is f(- 2x + 1) equal to?
Answer:
f(-2x+1)=-x -1/2
Step-by-step explanation:
f(-2x+1)= 1/2 * ( -2x + 1 ) - 1
f(-2x+1)=-x + 1/2 - 1

9514 1404 393
Answer:
b. g(x) = 0.5f(x)
Step-by-step explanation:
Compared to the line y=x, the graph of g(x) has a vertical scale factor of 1/2. We can also observe that the equation for g(x) is ...
g(x) = 1/2x
If we substitute f(x) for x, then this is ...
g(x) = 1/2f(x) . . . . matches choice B
