Which representation does not show a proportional relationship between x and y?
Answer:
Table A
Step-by-step explanation:
looking at the two tables, we have the observations as follows;
For table B, if we divide x by y; we have a ratio of 2/3
This happens throughout the table
What this means is that x = 2/3 * y
But for table A, we notice a pattern for the first two lines
The pattern here is that x = 2y
But as we move to the next two rows, we notice this fails and thus, we fail to establish a pattern that works for all the rows;
Hence table B has a pattern for all its rows

An experiment consists of spinning the spinners shown and adding the numbers together. Complete the array.
Answer:
[tex]\begin{array}{ccccc}{} & {1} & {2} & {3} & {4} & {1} & {2} & {3} & {4} & {5} & {2} & {3} & {4} & {5} & {6} & {3} & {4} & {5} & {6} & {7} & {4} & {5} & {6} & {6} & {8} \ \end{array}[/tex]
Step-by-step explanation:
Given
[tex]Spinner = \{1,2,3,4\}[/tex]
Array:
[tex]\begin{array}{ccccc}{} & {1} & {2} & {3} & {4} & {1} & {} & { } & { } & {5} & {2} & { } & {} & { } & { } & {3} & {4} & { } & {} & { } & {4} & { } & {6} & { } & {} \ \end{array}[/tex]
Required
Complete the blanks
To do this, we simply add up corresponding row and column elements.
[tex]\begin{array}{ccccc}{} & {1} & {2} & {3} & {4} & {1} & {} & { } & { } & {5} & {2} & { } & {} & { } & { } & {3} & {4} & { } & {} & { } & {4} & { } & {6} & { } & {} \ \end{array}[/tex]
So, we have:
[tex]\begin{array}{ccccc}{} & {1} & {2} & {3} & {4} & {1} & {1+1} & {1+2 } & {1+3 } & {4} & {2} & {2+1 } & {2+2} & {2+3 } & {2+4 } & {3} & {4} & {3+2 } & {3+3} & {3+4 } & {4} & {4+1 } & {6} & {4+3 } & {4+4} \ \end{array}[/tex]
Add
[tex]\begin{array}{ccccc}{} & {1} & {2} & {3} & {4} & {1} & {2} & {3} & {4} & {5} & {2} & {3} & {4} & {5} & {6} & {3} & {4} & {5} & {6} & {7} & {4} & {5} & {6} & {6} & {8} \ \end{array}[/tex]
Use the fraction strips to compare 2/4 and 5/8. use the drop-down menus to explain your comparison.
Comparing 2/4 and 5/8 is the same as comparing the length of ____ of the 1/4 sections and _____ of the 1/8 sections.
The sections of 2/4 is _____ the length of 5/8. Therefore, 2/4 < 5/8.
Answer:
[tex]\frac{2}{4} = 2 *\frac{1}{4} \\[/tex]
So the length of 2 of the 1/4 sections.
[tex]\frac{5}{8} = 5* \frac{1}{8}[/tex]
So the length of 5 of the 1/8 sections.
Now,
[tex]\frac{2}{4} = x *\frac{5}{8}\\\\x = \frac{2}{4} * \frac{8}{5} = \frac{16}{20} = \frac{4}{5}[/tex]
Therefore 2/4 is 4/5 the length of 5/8.

Consider the sequence 3/4, 4/5, 5/6, 6/7, . . .
Which statement describes the sequence?
A. The sequence diverges.
B. The sequence converges to 0.
C. The sequence converges to ∞.
D. The sequence converges to –∞.
Answer:
b is a correct answer

that is correct and right answer.
The sequence 3/4, 4/5, 5/6, 6/7, . . . is diverges option (A) The sequence diverges is correct.
What is the convergent of a series?
A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums get closer and closer to a certain number.
The sequence can be defined as the systematic way of representing the data that follows a certain rule of arithmetic.
It is given that:
The sequence:
3/4, 4/5, 5/6, 6/7, . . .
AS we know, the convergent sequence occurs when, as n approaches infinity, you arrive at a final and constant term through a number of terms.
Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.
The nth term of the sequence
a(n) = 2+n/3+n
Applying divergence test:
The sequence diverges
Thus, the sequence 3/4, 4/5, 5/6, 6/7, . . . is diverges option (A) The sequence diverges is correct.

Step-by-step explanation:
In an enclosure, there are 8 yellow chicks and 6 black and white chicks. The door opens and two chicks escape. What is the probability that both chicks were yellow?
Answer:4/13
Step-by-step explanation:
Number of yellow chicks = 8
Number of black and white chicks = 6
Total number of chicks = 8+6 = 14
The probability of the first yellow chick escaping will be 8 out of 14.
The probability of the second yellow chick escaping will be 7 out of 13 since there'll be 13 chicks left after the first yellow excaped.
Therefore, the probability that both chicks were yellow will be:
= 8/14 × 7/13
= 4/7 × 7/13
= 4/13
Therefore, the probability is 4/13.

Final answers:
Vertex: (1,9)Domain: all real numbers, or (-infinity, infinity)Range: (-infinity, 9]Maximum: 9; there is no minimumy-intercept: (0,8)Interval of increase: (-infinity, 1)Interval of decrease: (1, infinity)Average rate of change: 3 or -3Explanations
Vertex: this is the maximum or minimum point on the graph, which is (1,9).Domain: this is everywhere that the function is defined. Since there are no values of x for which -x^2 + 2x + 8 is not defined, the domain is all real numbers, or [tex](-\infty, \infty)[/tex].Range: this is all y-values the function takes. We can see from the graph that the function takes on all values less than or equal to 9, so the range is (-infinity, 9].Maximum or minimum: the maximum value is 9. There is no minimum value.y-intercept: this is the point where the graph intersects the y-axis, which is (0,8) or simply 8. You can think of this as the value of f(x) when x is zero.Interval of increase: f(x) is increasing on (-infinity, 1).Interval of decrease: f(x) is decreasing on (1, infinity).Average rate of change: the question is asking us to find the slope between the vertex and one of the x-intercepts – I will use (-2,0). The vertex is (1,9). The average rate of change is the slope between these points, which is (9-0)/(1-(-2)), or 3. If you instead used the x-intercept of (4,0), you would get an answer of -3.The radius of a circle is 7 ft. Find its area to the nearest tenth

3) Michael is getting dinner for his drama club on the evening of their final rehearsal.
The budget for dinner is $60
Michael plans to buy some prepared dishes from a supermarket. The prepared dishes are sold
by the pound, at $5.50 a pound
He also plans to buy two large bottles of sparkling water at $2.50 each
a) Write an inequality that represents the situation. (let p = weight of prepared dishes in pounds) 2
points
b) How many pounds of prepared dishes can Michael buy? Explain or show your reasoning, 3 points
Answer:
5.5p + 5 ≤ 60
10 pounds
Step-by-step explanation:
a) The maximum total cost he can spend is $60.
5.5 * p + 2 * 2.5 ≤ 60
Simplify.
5.5p + 5 ≤ 60
b) Solve 5.5p + 5 ≤ 60
Subtract 5 from both sides
5.5p ≤ 55
Divide both sides by 5.5
p ≤ 10
So, the maximum he can buy is 10 pounds of food
A cone has a slant height that measures 24 feet and a radius that measures 13.5 feet. What is the surface area of the cone?
Surface area of the cone is 1589.625 feet²
What is cone?A cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a point called an apex or vertex. A cone is formed by a series of line segments, half-lines, or lines connecting apex that is common to all points on the base that lie in a plane that does not contain the apex.
Given,
Slant height of the cone l = 24 feet
Radius of the cone r = 13.5 feet
Surface area of cone
= πr² + πrl
= 3.14(13.5)² + 3.14×13.5×24
= 3.14(182.25) + 3.14(324)
= 572.265 + 1017.36
= 1589.625 feet²
Hence, 1589.625 feet² is the surface area of the cone.

The area of a kite is 120cm2. The length of one diagonal is 20cm. What is the length of the other diagonal?
Answer:
12cm
Step-by-step explanation:
The area of a kite is the product of the diagonals divided by 2:
A = (d1 * d2)/2
You can substitute what we have:
120 = (20 * d2)/2
And solve.
240 = 20 * d2
d2 = 12cm
The length of the other diagonal is 12cm.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
