Use your graph to find how far the edge of the kiosk is from the entrance, to the nearest foot. Explain how you found your answer. (Hint: find the x-value for the point where y = 24 that is closest to the entrance.)
I've done the rest of the assignment, I just need help on this one question.
Using the graph of the scenario, the edge of the kiosk is 20 feet far from the entrance.
How to determine the distance of the edge ?The y value is given as:
y = 24
From the graph of this question (see attachment), we have the following coordinate
(x,y) = (20,24)
This means that the edge of the kiosk is 20 feet far from the entrance.

The following histogram shows the number of days during the school year that students bought lunch.
a. How many total students are at the school?
b. What is the probability that a randomly chosen student will by lunch between 10 and 20 times in a month?
The total number of students is 470.
The probability that a randomly chosen student will by lunch between 10 and 20 times in a month is 0.26.
What is the total number of students?
A histogram is used to represent data graphically. the histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval.
The total number of students = 140 + 120 + 80 + 40 + 30 + 60 = 470
What is the probability?The probability that a randomly chosen student will by lunch between 10 and 20 times in a month = number of students between 10 and 20 times / total number of students
(80 + 40) / 470 = 0.26

find the coordinates of the point where the line [tex]y=5x+7\\[/tex] crosses the [tex]y[/tex] axis
Answer:
(0, 7)
Step-by-step explanation:
The point that crosses the y-axis is called the y-intercept of the line.
We are given an equation of the line and we need to determine the y-intercept. This can be done by determining the constant in the equation.
What are constants?
Constants are such terms that include only numbers. There should be no variables in constants.
We know that:
[tex]\bullet \ \text{Given equation of line: y = 5x + 7}[/tex]
The constant we can see in the equation is "7". Therefore, the y-intercept is 7.
Note: The y-intercept of the line must have an x-coordinate of 0.
Therefore,
⇒ Coordinates of y-intercept: (x, y) ==> (0, 7).
Graph y = 3/4x + 2.
Help please!!!
Answer:

Here are the box plots of the number of calories in 20 brands of beef hot dogs, 17 brands of meat hot dogs, and 17 brands of poultry hot dogs. The plot shows
Answer:
A) most poultry hot dog brands have fewer calories than most beef and meat hot dogs, but a few poultry hot dogs have more calories than the median beef and meat hot dog
Step-by-step explanation:
i will refer to the first option as A) and so on
A)
the top of the poultry box represents the 75th percentile, so 75% of poultry values are at or below that number. this is lower than the median for both beef and meat (the middle lines in their respective boxes). if a value is lower than the median, that means that most values in the boxplot in question are higher than that value. here, this means that since the 75th percentile of poultry is less than the 50th percentile of beef/meat, most poultry hot dog brands have fewer calories than most beef and meat hot dogs
since the top line of the poultry chart extends past the mean of the beef/meat hot dogs, there are some poultry hot dogs that have higher calories than the mean for beef/meat
thus, this is the answer
B)
although it is true than some are high and some are low, we can see a general trend that beef and meat are higher than poultry, so this is wrong
C) since the 75th percentile for poultry is less than the median for beef/meet, we can say that >75% of poultry hot dog brands have fewer calories than the median for beef/meat. this is not "about half" so this is wrong
D) since the top of the poultry line extends past the mean for beef/meat, this is wrong
E) box plots do not give mean so this is wrong

If 60 kilovolts was used for a radiographic exposure and a 15 % increase is required, which of the following should be set by the technologist?
Step-by-step explanation:
there is nothing "following" here.
however, if I understand correctly, we need a 15% increase to 60 kV.
100% = 60 kV
1% = 100%/100 = 60/100 = 0.6 kV
15% = 1% × 15 = 0.6 × 15 = 9 kV
so, adding these 15% gives us
60 + 9 = 69 kV.
once we understand this mechanism, we can also use the shortcut : to add x% to something, we need to multiply this something by 1.x.
in our case, we want to increase 60kV by 15% ?
the result is
60 × 1.15 = 69 kV
simply because (as the top part should have shown too) x% of the whole = x/100 × whole.
so, to add x% means to have
100/100 × whole + x/100 × whole = 1.x × whole

On an exam, Mafuyu scored in the 20th percentile. If there were 50 students in the class, how many students scored lower than he did?
Using the percentile concept, it is found that 10 students scored lower than he did.
What is the meaning of the percentile of a measure?When a measure is in the xth percentile of a data-set, it is greater than x% of the measures and lesser than (100 - x)%.
In this problem, he scored on the 20th percentile, that is, higher than 20% of the 50 students. Then:
0.2 x 50 = 10.

Which triangle could be drawn as it is described ?
Answer: D
Step-by-step explanation:
Step-by-step explanation:
The side measures of choices A and C do not form a triangle of any sort.
The angle measures of choice B mean the remaining angle is ...
180° -110° -35° = 35°
Two of the angles are the same measure, so the triangle will be isosceles, not scalene. No scalene triangle can be formed with those angle measures.
__
The angle measures of choice D mean the remaining angle is ...
180° -20° -80° = 80°
Two of the angles are the same measure, so an isosceles triangle can be formed as described in choice D.

Applying the triangle proportionality theorem, the length of Jk in the diagram given is: 16 units.
What is the Triangle Proportionality Theorem?The triangle proportionality theorem states that when a side of a triangle is parallel to a line that intersects the other two sides of the triangle, then it divides the two sides of the triangle, proportionately.
Using the triangle proportionality theorem, we have the ratio if JK is x:
x/(36 - x) = (63 - 35)/35
x/(36 - x) = 28/35
35x = 28(36 - x)
35x = 1,008 - 28x
35x + 28x = 1,008
63x = 1,008
x = 16
JK is: 16 units.

What is the equation that represents g(x)? Explain your reasoning. 
Answer:
g(x) = log(x+1) +4
Step-by-step explanation:
The transformation ...
g(x) = f(x -h) +k
translates the graph of f(x) to the right h units and up k units.
__
Your graph shows g(x) is a translation of f(x) to the left 1 unit and up 4 units. That means the graph of g(x) can be described by ...
g(x) = f(x -(-1)) +4
g(x) = log(x+1) +4
_____
Additional comment
The vertical asymptote of f(x) at x=0 provides an identifiable feature for assessing the amount of horizontal shift. The vertical asymptote at x=-1 for g(x) means there was a left shift of 1 unit.
One unit to the right of the vertical asymptote, the graph of f(x) has an x-intercept (y=0). On the graph of g(x), one unit to the right of the vertical asymptote, the graph shows a value of y=4. This suggests an upward shift of 4 units.
We observe that the graph of g(x) generally matches the shape of the graph of f(x), so there is likely no horizontal or vertical scaling. A horizontal expansion factor of 'a' and a vertical expansion factor of 'b' would modify the function to ...
g(x) = b·f(x/a)

If you flip 11 coins, the probability of not getting all 11 tails is
The required probability of not getting all tails is 2037 / 2048.
Given that,
If you flip 11 coins, the probability of not getting all 11 tails is to be determined.
What is probability?
Probability can be defined as the ratio of favorable outcomes to the total number of events.
What is simplification?The process in mathematics to operate and interpret the function to make function simple or more understandable called simplify and the process is called simplification.
Since each coin has 2 possible outcomes for a single toss i.e either head or tail.
Total number of sample spaces for the 11 coins to be tossed = 2^11 = 2048
The number of favorable outcomes for all tails = 11
Probability of not getting all 11 tails = 1 - probability of all are tails
= 1 - 11 / 2048
= 2037 / 2048
Thus, the required probability of not getting all tails is 2037 / 2048.
