Describe what is happening in this graph with regards to the number of people in an amusement park on a summer day.
Answer:
The number is gradually increasing representing the people entering the park, the number becomes constant after a while , and lastly the people are starting to leave causing the decline on the graph.
Step-by-step explanation:
This the plebian explanation of how my teacher it.
The graph is showing the entry of the people in the amusement park.
What is a graph?A graph represents the data on the vertical and horizontal coordinates so we can see the trend of the data.
A graph is a structure that resembles a set of items in mathematics, more specifically in graph theory, in which some pairings of the objects are conceptually "connected."
The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.
As more people visit the park, the number progressively rises; after a while, it stabilizes; and finally, as more people start to leave, it begins to drop on the graph.
Therefore, the graph is showing the entry of the people in the amusement park.

Richard buys a carton of oranges and measures the weight of 1 orange in the carton Which measure gives the most precise weight?
Answer:
0.8 lbs
Step-by-step explanation:
Ounces are typically used to measure liquid, so I would discourage choosing the top two. And, hopefully you know by now that an orange does not weigh 8 pounds.
9514 1404 393
Answer:
(a) 0.8 ounces (most precision)
(b) 8 ounces (best precision for likely weight of an orange)
Step-by-step explanation:
The most precision is obtained by using the smallest unit of measure. On this list, the smallest unit of measure is a tenth of an ounce. That is, the measure 0.8 ounces has the most precision.
__
It is unlikely that the weight of one orange will be 0.8 ounces. The smallest unit used in a measurement likely to correspond to the weight of an orange is 1 ounce, used in the measurement 8 ounces. That measurement has better precision than 0.8 pounds, because 0.1 pounds corresponds to 1.6 ounces.

Using the binomial theorem, expand the expression (4 + y) to the power of 4
Answer:
When raised to the power of 4, the binomial (4 + y) expands to:

Answer:
- 5/6
Step-by-step explanation:
turn it into an improper fraction.
1 and 2/3 = 5/3
2 and 1/2 = 5/2
5/3 - 5/2 = 10/6 - 15/6
= -5/6
Answer:
First you have to change both of the mixed numbers to improper fractions. To do this you would multiply the denominator and the whole number then add the numerator.
1 2/3 = 5/3
-2 1/2 = -5/2
Find the least common denominator (LCM). Add the numerator, and keep the denominator the same.
The LCM for these two fractions would be 6 so to get to six you would multiply 5/3 by 2/2 and -5/2 by 3/3.
5/3 = 10/6
-5/2 = -15/6
Add the numerators (10 + -15 = -5), and keep the denominator the same (6). Therefore, the answer would be -5/6.

1. Based on the given information, set up a proportion;
Given;
1/6 of a bottle was filled in 1/4 minute
Equation;
1/6 : 1/4
2. Solve the equation;
1/6 : 1/4
Multiply both sides by 6, to make it such that the whole bottle is filled,
1/6 : 1/4
*6 *6

Simplify
1 : 3/2
1.5 minutes to fill a whole bottle.
the average of nadine's six test is 77. The scores on the five of the test are 88,65,75,83 and 90. what is the score on the remaining test?
A. 91
B. 81
C. 71
D. 61
Answer:
The score on the remaining test is x = 61
Hence, option D is correct.
Step-by-step explanation:
Let 'x' be the score of the remaining test
The average score of Nadine's six tests = 77
so
Average score = (88+65+75+83+90+x) / 6
substituting average score = 77 in the equation to find 'x'
77 = (401 + x) / 6
401 + x = 77 × 6
x = 462 - 401
x = 61
Therefore, the score on the remaining test is x = 61
Hence, option D is correct.

Robyn likes to read novels that have 400 pages or fewer. Which inequality represents the number of pages, p, in the novels she likes to read? A. p ≤ 400 B. p ≥ 400 C. p > 400 D. p < 400
Answer:
A
Step-by-step explanation:
P represents the page of number and she likes to read FEWER than 400 or equal to it. P < 400 says that she likes to read pages that are fewer or equal to 400 pages.
The inequality that represents the number of pages p is p ≤ 400.
Option A is the correct answer.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Number of pages = 400 or fewer
This means,
Number of pages ≤ 400
Thus,
p ≤ 400
where p is the number of pages.

Data on investments in the high-tech industry by venture capitalists are compiled by a corporation. A random sample of 18venture-capital investments in a certain business sector yielded the accompanying data, in millions of dollars. Determine and interpret a 95%confidence interval for the mean amount, mu,of all venture-capital investments in this business sector. Assume that the population standard deviation is $1.70million. (Note: The sum of the data is $102.52million.)
Answer:
$4.911 million or $6.481 million
Thus, we are 95% confident that the mean amount of all venture-capital investments in the high-tech industry is somewhere between $4.911 million and $6.481 million.
Step-by-step explanation:
Given that:
sample size n = 18
standard deviation σ = 1.70
confidence interval = 95%
Sample mean [tex]\overline x =\dfrac{ \sum x }{n}[/tex]
[tex]\overline x =\dfrac{ 102.52 }{18}[/tex]
[tex]\overline x =[/tex] 5.696
The level of significance = 1 - C.I
= 1 - 0.95
= 0.05
The critical value of [tex]Z_{\alpha/2} = Z_{0.025} = 1.960[/tex] from the Z tables
The 95% C.I for the mean is;
[tex]= \overline x \pm Z_{\alpha/2} \times \dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]=5.696 \pm 1.960 \times \dfrac{1.70}{\sqrt{18}}[/tex]
[tex]=5.696 \pm 1.960 \times \dfrac{1.70}{4.243}[/tex]
[tex]=5.696 \pm 1.960 \times 0.4007[/tex]
= 5.696 ± 0.785372
= (5.696 - 0.785372 , 5.696 + 0.785372 )
= ( 4.910628 , 6.481372 )
≅ $4.911 million or $6.481 million.
Thus, we are 95% confident that the mean amount of all venture-capital investments in the high-tech industry is somewhere between $4.911 million and $6.481 million.
Point Q lies on the circle and has an X-coordinate of 4. Which value could be the y-coordinate for point Q?
We are not given the radius of the circle or any other relevant data, so I assumed the radius of the circle r=5
Answer:
The y-coordinate of Q is 3
Step-by-step explanation:
Circles and Lines
The figure below shows a circle of radius r=5 and a segment that goes from the center of the circle to a point of the circumference, where x=4.
We can find the y-coordinate of that point by using Pithagora's theorem:
[tex]r^2=x^2+y^2[/tex]
Solving for y:
[tex]y^2=r^2-x^2[/tex]
[tex]y^2=5^2-4^2[/tex]
[tex]y^2=25-16=9[/tex]
[tex]y=\sqrt{9}=3[/tex]
The y-coordinate of Q is 3
