Emilio is drawing a graph that shows the weight of a baby elephant during the first 6 months of its life. What is the meaning of the point shown on the graph?
Ruby's Weight
A graph has age (months) on the x-axis, and weight (pounds) on the y-axis. A point is at (1, 80).
Using the function concept, it is found that the meaning of the point is that the weight of the elephant during the first month is of 80 pounds.
What is a function?In a function, represented by a set of ordered points (x,y), one value of the input x can be related to only one value of the output y.
In this problem, x is the age in months, while y is the weight in pounds, hence the meaning of point (1,80) is that the weight of the elephant during the first month is of 80 pounds.

wild touring the city Bernie buys lunch for his family from a food truck he purchase more Taco for 2.75 and four cheeseburgers if he spent a total of 23.75 how much was each cheeseburger
Answer:
Each cheeseburger was $5.25.
Step-by-step explanation:
He purchased:
A taco for $2.75.
Four cheeseburgers, each for x.
In total, he spent $23.75.
How much was each cheeseburger?
This is the value of x. We have that:
[tex]2.75 + 4x = 23.75[/tex]
[tex]4x = 21[/tex]
[tex]x = \frac{21}{4}[/tex]
[tex]x = 5.25[/tex]
Each cheeseburger was $5.25.
Find x if (2.5)^x-3 = (0.4)^6+x
Answer:
2.5x=x+3.004096
Sorry, I don't know how to solve this equation.
Step-by-step explanation:
A reproductive clinic had a success rate of 25% of patients with live births in 2008. They want to update their success rate (the proportion of live births) for 2020. If they want their estimate to be within 2.5%, how many patient's results should they sample if they plan to use a 99% confidence interval? Round your answer up to the nearest integer.
Answer:
They should sample the results of 1990 patient results.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
A reproductive clinic had a success rate of 25% of patients with live births in 2008.
This means that [tex]\pi = 0.25[/tex]
99% confidence level
So [tex]\alpha = 0.01[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].
If they want their estimate to be within 2.5%, how many patient's results should they sample if they plan to use a 99% confidence interval?
They should sample n patients.
n is found for [tex]M = 0.025[/tex]. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.025 = 2.575\sqrt{\frac{0.25*0.75}{n}}[/tex]
[tex]0.025\sqrt{n} = 2.575\sqrt{0.25*0.75}[/tex]
[tex]\sqrt{n} = \frac{2.575\sqrt{0.25*0.75}}{0.025}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.575\sqrt{0.25*0.75}}{0.025})^2[/tex]
[tex]n = 1989.2[/tex]
Rounding up:
They should sample the results of 1990 patient results.
Carmel is watching a play at the theatre.
The play started at 16 30
The play is 115 minutes long.
When the play ends, Carmel takes 30 minutes to get to the bus stop.
A bus leaves the bus stop at 18 45
Does Carmel get to the bus stop in time to get this bus?
You must show all your working.
Need help
Step-by-step explanation:
play started 16:30
its 115 min long = 1:55 hours
16:30+ 1:55=18:25 hours
now he takes 30 min to reach bus stop
18:25 + 30 mins = 18:55
therefore, he reaches the bus stop 10 mins late

Step-by-step explanation:
Gabriel earns $146.25 for working 15 hours. Maria earns $205.00 for working 20 hours. Who earns the most money per hour and how much more?
Please help have to turn in tomorrow
you get 15 points!!!!
Answer: Maria makes $0.50 more per hour
Step-by-step explanation: Doing $146.25/15 and $205/20 you can find that Gabriel makes $9.75/hr and Maria makes $10.25/hr
Answer: Maria makes more, 50 cents more per hour.
Step-by-step explanation:
To solve divide the number of money they made by the amount of hours they worked. 146.25/15=9.75. Gabriel made 9.75 an hour,
205/20=10.25 Maria made 10.25 an hour.
Maria earned the most money per hour.
To find how much more she made subtract the person who made more money by the person who made less money per hour. 10.25-9.75=0.5 Maria earned an extra 50 cents per hour compared to Gabriel.

Right-Side Limit: [tex]\displaystyle \lim_{x \to c^+} f(x)[/tex]Left-Side Limit: [tex]\displaystyle \lim_{x \to c^-} f(x)[/tex]Limit Rule [Variable Direct Substitution]: [tex]\displaystyle \lim_{x \to c} x = c[/tex]

Step 1: Define
Identify
[tex]\displaystyle f(x) = \left\{\begin{array}{ccc}5 - x ,\ x < 5\\8 ,\ x = 5\\x + 3 ,\ x > 5\end{array}[/tex]
Step 2: Find Left-Side Limit
Substitute in function [Left-Side Limit]: [tex]\displaystyle \lim_{x \to 5^-} 5 - x[/tex]Evaluate limit [Limit Rule - Variable Direct Substitution]: [tex]\displaystyle \lim_{x \to 5^-} 5 - x = 5- 5 = 0[/tex]Step 2: Find Left-Side Limit
Substitute in function [Right-Side Limit]: [tex]\displaystyle \lim_{x \to 5^+} x + 3[/tex]Evaluate limit [Limit Rule - Variable Direct Substitution]: [tex]\displaystyle \lim_{x \to 5^+} x + 3 = 5 + 3 = 8[/tex]∴ since [tex]\displaystyle \lim_{x \to c^+} f(x) \neq \lim_{x \to c^-} f(x)[/tex] , [tex]\displaystyle \lim_{x \to 5} f(x) = \text{DNE}[/tex]

1. True or false:
The ordered pair (3, 4) is a solution for the equation:
5x + 2y = 23
2. True or false:
The ordered pair (0, 4) is a solution for the equation:
5x + 2y = 23
1) true
2)false
Step-by-step explanation:
1) 5(3)+2(4) = 23
= 15+8=23
23=23
thus, (3,4) is solution for 5x + 2y = 23
2) 5(0)+2(4) =23
= 0+8 is not 23
thus, (0,4) is not solution for 5x + 2y = 23

Answer: Sorry, I'm not the best at this and I don't have a full answer but I can offer a tip!
X does not repeat if it is a function.
So, if you are finding the function it is one where x is different every time
Step-by-step explanation:
Based on the given graph, we can infer and logically conclude that the values of x for which this function is continuous is equal to zero (0).
What is a continuous function?A continuous function can be defined as a type of function in which there is no discontinuities or breaks between the intervals for the points plotted on a graph.
By critically observing the graph, we can infer and logically conclude that the values of x for which the function is continuous is zero (0) because it marks the point of continuity.
