Answer:
Part A:
x > 13
Part B:
How to show this inequality on a number line is a closed circle on 13, going left of 13.
Step-by-step explanation:
Part A:
x represents the age of children who are allowed to operate the boat.
Our inequality is < because if you are of the age of 13 you are allowed to operate the boat,
the inequality x > 13 reads x (the age of children) is greater than or equal to 13
Part B:
How to describe inequalities on a number line;
Closed circle: less than or equal to - or - greater than or equal to ( < , > )
Open circle: less than - or - greater than ( < , > )

Sandy used a virtual coin toss app to show the results of flipping a coin 100 times, 500 times, and 1,000 times. Explain what most likely happened in Sandy's experiment.
Sandy's experimental probability was closest to the theoretical probability in the experiment with 100 flips.
Sandy's experimental probability was closest to the theoretical probability in the experiment with 500 flips.
Sandy's experimental probability was closest to the theoretical probability in the experiment with 1,000 flips.
Sandy's experimental probability was exactly the same as the theoretical probability for all three experiments.
Answer:
Step-by-step explanation:
To determine what most likely happened in Sandy's experiment, we need additional data on the outcomes of the virtual coin tosses in each experiment. Without this data, we cannot directly compare the experimental probability to the theoretical probability.
However, we can make some general observations based on the law of large numbers and the concept of convergence. The law of large numbers states that as the number of trials or experiments increases, the experimental results tend to converge towards the theoretical probabilities. This means that with a larger number of flips, the experimental probability is more likely to be closer to the theoretical probability.
Therefore, based on this principle, it is reasonable to assume that Sandy's experimental probability was likely closest to the theoretical probability in the experiment with 1,000 flips. As the number of flips increases, the chances of the experimental results aligning closely with the theoretical probability increase.
However, it is important to note that without the specific data on the outcomes of each experiment, we cannot definitively determine which experiment had the experimental probability closest to the theoretical probability.

I need help on a b and function 2
I dont get it
Answer:
For A: The first function has a greater ROC
For B: The first function has a negative slope
Step-by-step explanation:
Explication for A:
We already know that the R.O.C. (slope) is 2 for the first function, so all we need to do is substitute the values in the table into the following formula: y2-y1/x2-x1
after substituting: (-3-(-6))/(0-(-1))
simplify 3/1=3, since the ROC is 3, the second equation has a greater ROC than the first
Explanation for B:
The first function described is f(x)=20-3.5x
This is because the y intercept is the starting point, or how much money she has in the gift card. She spends 3.5 dollars per week, so we add a variable to represent the number of weeks, and its negative since she is spending, not earning. We also know that the slope is negative since y is decreasing as x is increasing, on the table.
The second function described is c(m)=5x+10
This is because the equation represents the total cost of renting a calculator, so both terms are positive.
To make a number pattern, Shana used the rule "Add 3," with a whole number as the starting number. Which statement must be true about Shana's list of numbers?
Answer:

Hailey goes to a restaurant and the subtotal on the bill was x dollars. A tax of 7% is applied to the bill. Hailey decides to leave a tip of 20% on the entire bill (including the tax). Write an expression in terms of x that represents the total amount that Hailey paid.
The total amount that Hailey paid can be represented by the following expression in terms of x:
Total amount = x + 0.07x + 0.20(x + 0.07x)
Simplifying the equation, we get:
Total amount = x + 0.07x + 0.20(1.07x)
Total amount = x + 0.07x + 0.214x
Total amount = 1.284x
Therefore, the expression in terms of x that represents the total amount that Hailey paid is 1.284x.
What is the area of the figure below
Answer:224
Step-by-step explanation:
Okay as you can see, the figure is divided into 3 shapes. 2 rectangles and a right trapezoid.
You can solve the area of the rectangle on the far right by doing 9x6 leaving you with 54.
For the other rectangles you can do 11x12 equaling 132. I got 11 because you know the top is 17 and as you see at the bottom that length you used for the first rectangle is 6, so you do 17-6. You get 12 from adding 9+3.
For the right trapezoid the formula is A = ( a + b ) x h/2. So you can plug it in and say A=(12+7) x 4/2= 38.
You then add all the areas together (54+132+38= 224) leaving you with the answer of 224.

A. five hundred fifty and one-fourth cm2
B. four hundred twelve and three-fourths cm2
C. two hundred seventy-five and one-eighth cm2
D. one hundred thirty-seven and nine-sixteenths cm2
Answer:
the surface area of the rectangular prism is found as : S = 275 ¹/₈ cm².
Length l = 11 ³/₄ cm = 47/4 cm = 11.75 cm
width w = 5 ³/₄ cm = 23/4 cm = 5.75 cm
height h = 4 cm
surface area of the prism S = 2(lw + wh + hl)
S = 2(11.75*5.75 + 5.75*4 + 4*11.75)
S = 2*137.5625
S = 275.125
S = 275 ¹/₈ cm²

ASAP: Which equation best represents the line of best fit for the data in the scatterplot above?
Answer:
F : y = -x + 4
Step-by-step explanation:
The first observation about this scatterplot is that the best line of fit will be a line going diagonally from top left to bottom right(or bottom right to top left)
Such a line has negative slope
Equation will be of the form
y = mx + b where m is a negative number
We can eliminate H and I since both lines have a positive slope which means that the line will go in a diagonal bottom left to top right direction
Let's examine options F and G
F: y = - x + 4
G: -9x + 3
Plug in some values for x from the graph and see which of the lines comes closest to the y values computed from the equations
At x = -5, the y value from the graph appears to be either 7 or 8
F: y = -x + 4 ==> -(-5) + 4 = 5 + 4 = 9; pretty close to graph's point value
G: -9x + 3 ==> -9(-5) + 3 = 45 + 3 = 48; this is greatly different from the graph value
At x = 0; the y value from graph is close to 4
From the equations we get
F: y = -x + 4 ==> y = -(0) + 4 = 4; pretty darn close
G: y -9x + 3 => y = -9 + 3 = -6; large difference
One more point
At x = 20, the point on the graph appears to be close to -19
From the equations we get
F: y = -x + 4 = -20 + 4 = -16; not too different
G: y = -9x + 3 = -9(20) + 3 = -180 + 3 = 177; way off
So the best line of fit would be
F : y = -x + 4
The equation that best represents the line of fit from the scatter plot is given as follows:
y = -x + 4.
How to define a linear function?The slope-intercept representation of a linear function is given by the equation shown as follows:
y = mx + b
The coefficients m and b have the meaning presented as follows:
m is the slope of the function, representing the increase/decrease in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, representing the numeric value of the function when the input variable x has a value of 0. On a graph, it is the value of y when the graph of the function crosses or touches the y-axis.From the scatter plot, we have that when x = 0, y = 4, hence the intercept b is given as follows:
b = 4.
When x = 20, y is approximately -16, hence the slope m is obtained as follows:
-16 = 20m + 4
20m = -20
m = -1.
Hence the function is:
y = -x + 4.

ONLY PEOPLE WITH REAL AWNSERS!!
Answer:
7:20 p.m.
Step-by-step explanation:
First, we can find the distance that each friend will be from their house at the time when they meet each other.
To find this, we can multiply the ratio [tex]8 \text{ mi} : 7 \text{ mi}[/tex] by a constant such that the sum of both numbers in the ratio is 20, since the friends' houses are 20 miles apart. Solving for this constant:
[tex]\dfrac{20}{7 + 8} \\ \\ = \dfrac{20}{15} \\ \\ \boxed{=\dfrac{4}{3}}[/tex]
Multiplying the constant by both sides of the ratio:
[tex]\dfrac{4}{3}\left(8 \text{ mi}) : (7 \text{ mi}\right)\dfrac{4}{3}[/tex]
[tex]\boxed{= \dfrac{32}{3} \text{ mi} : \dfrac{28}{3} \text{ mi}\right)}[/tex]
So, we know that the first friend will have traveled 32/3 or 10 2⁄3 miles when they meet, and the second friend will have traveled 28/3 or 7 1⁄3 miles.
Now, to calculate what time they will meet, we can divide how far one of the friends has traveled by how fast they were traveling. This will give us the minutes it will take them to get to the meeting place. We can then add that amount of minutes to 6:00 p.m. to calculate when they will meet.
I will use the fast friend (traveling at 8 mph).
[tex]\dfrac{32}{3} \text{ mi} \cdot \dfrac{60 \text{ min}}{8 \text{ mi}}[/tex]
— Also note that I substituted 1 hour for 60 minutes in the mph ratio.
[tex]= \dfrac{32}{3} \not\text{mi} \cdot \dfrac{60 \text{ min}}{8 \not\text{mi}}[/tex]
[tex]= \dfrac{32 \cdot 60}{3 \cdot 8} \text{ min}[/tex]
[tex]= \dfrac{32}{8} \cdot \dfrac{60}{3} \text{ min}[/tex]
[tex]= 4 \cdot 20 \text{ min}[/tex]
[tex]\boxed{= 80\text{ min}}[/tex]
Adding those minutes to 6:00, noting that 80 min = 1 hr 20 min:
[tex]\text{ } \ \, 6\!:\!00 \text{ p.m.}\\\underline{+ 1\!:\!20}\\\\\text{ }\, \boxed{7\!:\!20 \text{ p.m.}}[/tex]
So, the friends will meet at 7:20 p.m.
