For each question, decide whether or not it is a function. PLEASE HELP ASAP ALEKES ALGEBRA 2 MATH ILL GIVE BRAINLIEST
Your answers are right because the x's can not repeat
so 1.it is a function
2.it is a function
3.it is not a function bc "d" and "m" both repeat 2 times
4.it is not a function bc 2 repeats 2 times
Hope this helps

Your building plan for your restaurant includes one men's and women's restroom. The city inspector lets you kno that you must have at least 400 square feet per bathroom. If your building is a total 4,000 square feet, how many square feet are left for the development other nonbathroom areas?
Answer: 3200 ft^2
Step-by-step explanation:
You have a total area of 4,000 ft^2.
In your plan, you will make two bathrooms (one men's restroom and one women's restroom)
We know that each one of them needs 400ft^2, then the total area needed is two times 400ft^2, or:
2*400ft^2 = 800ft^2
If we subtract this to the total area, we get:
4000ft^2 - 800ft^2 = 3200 ft^2
That is the square feet left for the development of other nonbathroom areas.
Data was collected on the amount of food (in grams) served at two restaurants and the price paid for the meal. The regression line for the data appears on the first plot. The second plot shows the regression analysis conducted when the data is analyzed separately for each of the two restaurants. Which of the following statements best describes the relationship between the variables?
a. The correlation between amount of food served and price is very strong within each restaurant, but seems weak when both restaurants are combined.
b. The correlation between amount of food served and price is strong.
c. The correlation between amount of food served and price is weak within each restaurant, but seems strong when both restaurants are combined.
d. The correlation between amount of food served and price is weak.
Answer:
Option A, The correlation between amount of food served and price is very strong within each restaurant, but seems weak when both restaurants are combined.
Step-by-step explanation:
The graphs for this question are provided in the attachment
Solution -
Graph I - the data points in the graph I do not follow any best fit curve or trendline. This indicates that data is not correlated.
Graph -II In graph II, apart from few outliners majority of data points lie on the best fist curve or the trendline.
Hence, the relation between the two variables i.e food served and price is strong.
Option A fits well for our answer hence it is the correct answer

David and Lucy have sweets in the ratio 4:7. Lucy has
27 more sweets. How many does David have?
Answer:
David share is 36 sweets
Step-by-step explanation:
let Lucy share be x
let David share be y
Lucy has 27 more
x=y+27
total sweet is x+y
y+27 +y= 2y+27
total ratio = 4+7=11
David share=
[tex]y = \frac{4}{11} \times (2y + 27)[/tex]
[tex]11y = 4(2y + 27)[/tex]
[tex]11y = 8y + 108[/tex]
[tex]11 y- 8y = 108[/tex]
[tex]3y = 108[/tex]
y=108/3= 36

Answer:
.34
Step-by-step explanation:
By using the table you would look at 3 (what the question wants which would be the x-value) and the y-value would be the answer.
Or you can use this calculator https://stattrek.com/online-calculator/binomial.aspx
and put in 55% for the success
5 for the amount of trials
and 3 for the success of the trials
calculated and you get .336 or rounded .34

Which expression represents 3 times the sum of 7 and m ?
Answer:
3 (7+m)
Step-by-step explanation:
The correct expression is,
⇒ 3 (7 + m)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The algebraic expression is,
''3 times the sum of 7 and m''
Now, We can formulate;
⇒ 3 × (7 + m)
⇒ 3 (7 + m)
Thus, The correct expression is,
⇒ 3 (7 + m)

3. Two coins are simultaneously tossed until one of them comes up a head and the other a tail. The first coin comes up a head with probability p and the second with probability q. All tosses are assumed independent. (a) Find the PMF, the expected value, and the variance of the number of tosses. (b) What is the probability that the last toss of the first coin is a head
Answer:
Step-by-step explanation:
From above-given information
Consider p to be the probability that the first coin comes up as head
Consider q to be the probability that the second coin comes up as tail.
Provided all tosses seems to be independent.
Then;
Let X represent no. of tosses, where X follows a geometric distribution with parameter;
p' = p(1-q) +q(1-p)
with probability mass function (pmf)
[tex]P(X = x) = ( 1 - p')^{x - 1} p'[/tex]
Thus, the mean (expected value) and the standard deviation can be computed as:
[tex]E(X) = \dfrac{1}{p'}[/tex]
[tex]\mathbf{E(X) = \dfrac{1}{p(1-q)+q(1-p)}}[/tex]
[tex]V(X) = \dfrac{1-p'}{(p')^2}[/tex]
[tex]\mathbf{V(X) = \dfrac{1-[p(1-q)+q(1-p)]}{[p(1-q)+q(1-p)]^2}}[/tex]
(b)
Suppose X represents that the first coin is head;
and Y represent the last toss
Therefore, the required probability is:
[tex]P(X|Y) = \dfrac{p(1-q)}{p'}[/tex]
[tex]P(X|Y) = \dfrac{p(1-q)}{p(1-q)+(1-p)q}[/tex]
