Draw a mapping diagram for the given
relation. Is it a function?
{(3,-1), (6, 4), (8,4)}?
Answer:
It is not technically a function. This is because by definition, a function should produce a distinct output value for every unique input value. In this case 8 and 6 both give you four, so it is not a function.

Scott drinks 6 cups of water a day. How many fluid ounces of water does Scott drink? (2 points)
Group of answer choices
36 fluid ounces
48 fluid ounces
52 fluid ounces
68 fluid ounces if your right I give u a lot of points
There are 48 fluid ounces of water Scott drink.
Define the term ounces?An ounce is a unit of measurement of weight or mass in both the US customary system and the British imperial system. In the US customary system, one fluid ounce of water weighs about 1.04 ounces (oz).
Each day, Scott consumes 48 fluid ounces of water.
To convert cups to fluid ounces, we need to multiply the number of cups by 8 (as there are 8 fluid ounces in one cup).
So, 6 cups of water is equal to:
6 cups × 8 fluid ounces per cup = 48 fluid ounces
Therefore, there are 48 fluid ounces of water Scott drink.

What is the equation of a circle with a center at (−3, 2) and radius 16?
Answer:
(x+3)^2 + (y+2)^2 = 16
Step-by-step explanation:
hi!
so the equation of a circle with the center (h,k) and a radius r is:
(x-h)^2+(y+k)^2 = r^2
- h is the x value
- k is the y value
- r is the radius
so using your information you can plug in the given values into the "blanket" formula
which would result in:
(x--3)^2 + (y+2)^2 = 16^2 --> since there is a double negative, you can change that to a positive :)
this means that your equation is:
[tex](x+3)^{2} + (y+2)^{2} = 16^2[/tex]
and you can even simplify 16^2 = 256
end formula!
[tex](x+3)^{2} +(y+2)^{2} = 256[/tex]

Ashley and Emma are reading the same article. Ashley is on page 1 of the article, but she can read 1 page per minute. Emma is already on page 5, but reads a page every 3 minutes.
What page is Ashley on after 5 minutes.
What equation can be used to represent the amount Emma has read?
How many minutes does it take before Ashley and Emma have read the same amount
Answer:
Part A)
Ashley will be on the sixth page.
Part B)
[tex]\displaystyle p=\frac{1}{3}m+5[/tex]
Part C)
Six minutes.
Step-by-step explanation:
Ashley is on the first page and she can read one page per minute.
Emma is on the fifth page and she can read one page every three minutes.
Part A)
We can write an equation for Ashley. Let m represent the amount of minutes that has passed.
Since she is already one the first page, our initial value is 1.
She reads one page every minute. So, after m minutes, she would have read m pages.
Therefore, our equation is:
[tex]p=m+1[/tex]
Where p is the total pages read after m minutes.
Then after five minutes, Ashley will be on the:
[tex]p=(5)+1=6[/tex]
Ashley will be on the sixth page after five minutes.
Part B)
Since Emma reads one page every three minutes, we can say that she reads 1/3 of a page every minute.
Since she started on page five, her equation is:
[tex]\displaystyle p=\frac{1}{3}m+5[/tex]
Part C)
So, both of their pages read must be equivalent. Therefore:
[tex]\displaystyle m+1=\frac{1}{3}m+5[/tex]
Solve for m. Subtract 1/3m from both sides:
[tex]\displaystyle \frac{2}{3}m+1=5[/tex]
Subtract 1 from both sides:
[tex]\displaystyle \frac{2}{3}m=4[/tex]
Finally, multiply both sides by 3/2:
[tex]\displaystyle m=4\Big(\frac{3}{2}\Big)=6[/tex]
So, it will take six minutes before Ashley and Emma have read the same number of pages.

The chart below shows the number of students in each grade who are members of the spirit club at Lone Star Middle School.
If 10 more 8th graders join the club, how many 6th graders will need to join the club so that the ratio of 8th graders to 6th graders remains the same?
Answer:
The Answer Is 6
Step-by-step explanation:
The number of students 6th graders who will need to join the club will be 18.
What is the ratio?The utilization of two or more additional numbers that compares is known as the ratio.
The chart below displays the number of students in each grade that are members of Lone Star Middle School's spirit club.
If ten additional eighth-grade students join the group. If the ratio of eighth students to sixth graders remains constant.
Let 'x' be the number of students who join the club in 6th grade. Then the equation is given as,
x / (2 × 10 + 10) = 6 / 10
Simplify the equation, then we have
x / (2 × 10 + 10) = 6 / 10
x / 30 = 3 / 5
x = 30 (3/5)
x = 18
The number of students 6th graders who will need to join the club will be 18.

Answer: C 30 it was correct on my test
The estimated probability that at least two of the puppies will be female is 60%.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
Let heads (H) be the female puppy
Let tails (T) be the male puppy.
The simulation results are the sample spaces.
[tex](THTT, TTTH, TTHH, HTTT, TTTT, HHHH, HTHT, HHHT, THTH, THTH)[/tex]
⇒ [tex]n(s)=10[/tex]
The event is the probability that at least two of the puppies will be
female.
[tex]e=(TTHH, HHHH, HTHT, HHHT, THTH, THTH )\\[/tex]
⇒ [tex]n(e)=6[/tex]
The estimated probability that at least two of the puppies will be
female, [tex]P(e)=\frac{n(e)}{n(s)}[/tex]
⇒ [tex]P(e)=\frac{6}{10}[/tex]
⇒ [tex]P(e)=0.6[/tex]
Thus the percentage of the female puppies = [tex](0.6)(100)[/tex]
⇒ [tex]60\%[/tex]
Hence we can conclude that the estimated probability that at least two of the puppies will be female is 60%.
