Which of the following could be the missing value?
b. 60%
c. 5.8
d. √23

Answers
The erased value in the descending order series is 5.8 so option (C) will be correct.
What is a series?A series follows some pattern for example if you take data set of natural numbers then there will be a sequence of that data and something will be due to that we can form that series.
Given the descending order series ;
31/5,---- 5 1/2, √26
Since the series is descending its means every next term must be smaller than the previous.
In the given option
6 1/4 = 6.25 and 31/5 = 6.2 so 6.25 > 6.2 so it will not the missing term.
60% refers to 0.60 but 5 1/2 > 0.60 so it is also no solution.
5.8 < 6.2 and 5 1/2 < 5.8 so it will be the solution.
Last √23 = 4.795 but 5 1/2 > 4.795 so it will also not solution.
Hence "The erased value in the descending order series is 5.8".

3
y = one-half x + 3
4
y = three-halves x + 1
According to the trend line equations, which plants are growing at the same rate per day?
Answers
The plants which are growing at the same rate are Plant 1 and Plant 4.
Both the plants are growing at the same rate because they have same slope when their growth rate is expressed in the form of equation. Slope may be defined as the amount of steepness of the graph when plotted on graph paper. The slope-intercept form of equation of line is given by y = mx + c where m is the slope of the line and c is the intercept formed by the line. The slope-intercept form of the growth rate equation of Plant 1 is given by y = 3/2x + 3/2 and the slope-intercept form of the growth rate equation of Plant 4 is given by y = 3/2x + 1.
If we compare them from the slope-intercept form of line, then both the Plants have same slope and thus their growth rate is same.

How to understand algebra 1 dot plots
Answers
We can understand dot plot by taking example of be the choice of foods that you and your friends ate for snacks.
A dot plot is a type of graphical display that uses filled circles (dots) and a simple scale to compare counts (frequencies) within a category or group when working with small data sets with few groups . A chart with letters or words (non-numeric categories) on the x-axis is called a qualitative dot plot. The dot plot above is a qualitative dot plot because A, E, I, O, and U are not numeric. Qualitative variables cannot be described in terms of center, spread, or shape. If the x-axis contains numbers (numerical categories), it is called a quantitative dot plot. This dot plot can be described in terms of center, spread, or shape.Dot plots are used to represent small amounts of data. To analyze this chart, let's say four people are having a snack together. Snack selections are pizza, burgers, fries, and pasta. Using the dot plant, we can see that everyone chose pizza. Also, her 3 other people in your group added burgers to their snack plates. The graph also shows that two people in the group added French fries and one person in the group added pasta to their meal.

Answer:
1a. -( x + 1)² + 4
1b. y-intercept at y = 3
1c. x-intercepts at x = -3 and x = 1
Derivation of 1b and 1c below
Step-by-step explanation:
Question 1a
The vertex equation form of a parabola is given by
y = a(x-h)² + k where (h, k) are the coordinates of the vertex
If a > 0 then the parabola is facing up(vertex is at a minimum) and if a < 0 then parabola is facing down (vertex at a maximum)
From the graph we see that the parabola is facing down so a = -1
The vertex is at (-1, 4) so h = -1 and k = 4
Therefore the equation of the parabola is
y = -1(x - h)² + k = -1(x- (-1))² + 4 = -1(x + 1)² + 4
y = -( x + 1)² + 4 (Answer 1a)
Question 1b
The y-intercept is the y-value where the parabola crosses the y-axis. From the graph we see that the parabola crosses the y-axis at y = 3 and x = 0
So y-intercept from the graph is 3
To solve algebraically, set x = 0 in the parabola equation and solve for y
We get, for x = 0,
y = - (0 + 1)² + 4
y = -(1²) + 4 = -1 + 4 = 3
Hence verified
Question 1c
There will be two x-intercepts for a parabola. Looking at the graph we see that the parabola intersects the x-axis at two points (-3, 0) and (1, 0). So the two x-intercepts are -3 and 1
Algebraically we can determine the x-intercepts by setting y = 0 and solving for the two values of x
Setting y = 0 in the parabolic equation, we get
y = 0 = -(x + 1)² + 4
Switch sides
-(x + 1)² + 4 = 0
-(x + 1)² = -(x² + 2x + 1) = -x² -2x - 1
-(x + 1)² + 4 = 0
==> -x² -2x - 1 + 4 = 0
==> -x² - 2x +3 = 0
Multiply by -1 both sides
==> x² + 2x - 3 = 0
Solve this quadratic equation by factoring
x² + 2x - 3 = (x - 1)(x + 3) = 0
The solutions are
x - 1 = 0 ==> x = 1
x + 3 = 0 ==> x = -3
Hence verified

Arthur is 7 years older than his brother. In 8 years, Arthur will be twice his brother's current age. How old is Arthur now?
Answers
Answer:
15 years old
Step-by-step explanation:
Answer: 22
Step-by-step explanation:
this problem is solved by a system of equations
Let Arthur’s current age be represented by:a
His brother’s current age will be represented by: b
The first equation will be:
a = 7 + b
The second equation will be:
a + 8 = 2b
now we solve for the equations. Plug in a = 7+b into a in the second equation.
So now we have
b+7+8=2b
Simplify:
B+15=2b
15=b
We aren’t done yet though
Arthur’s brother is 15 years old but since he is 7 years older we need to add 7 to 15
Hence, Arthur is 22 years old.

In triangle PQR,work out the values of a ,b and c.Give your reason for you answer .
Answers
Answer:
m∠a = 100°
m∠b = 100°
m∠c = 110°
Step-by-step explanation:
Calculation of m∠a
∠a is an exterior angle of ΔPST .
Therefore m∠a = sum of the interior angles of ΔPST
m∠a = 30 + 70 = 100°
Calculation of m∠c
∠c and ∠PST are supplementary so their measures must add up to 180°
m∠c + 70° = 180° so m∠c = 180 - 70 = 110°
Calculation of m∠b
QRST is a quadrilateral.
The sum of the interior angles of the quadrilateral = 360°
So m∠a + m∠b + 50 + m∠c = 360°
We have already computed ∠a = 100° and ∠c = 110°
So 100 + m∠b + 50 + 110 = 360°
260 + m∠b = 360
m∠b = 360 - 260 = 100°

Step 1 - In the lower section, enter 'x' as the total number of seats.
So, based on the data provided, the total number of seats in the upper field is '3x'. Let y be the total number of seats in the field.Step 2 - The linear equation that represents total ticket revenue.
80x + 60(3x) + 40y = 1140000260x + 40y = 1140000 ...(1)Step 3 - The linear equation representing the total number of tickets is as follows:
x + 3x + y = 24200y = 24200 - 4x ...(2)Step 4: Change the value of y in the equation (1).
260x + 40(24200 - 4x) = 1140000x = 1720 ticketsStep 5: Change the value of 'x' in equation (2).
y = 24200 - 4(1720)y = 17320 ticketsTherefore, the number of each ticket sold was:

In a random sample of 7 residents of the state of texas ,the mean waste recycled per person per day was 1.01 pounds and standard deviation 0.29 pounds
we have to find the 98% confidence interval for the mean waste recycled per person per day for the population of texas
Mean, xbar = 1.01
Standard deviation, s = 0.29
Sample size, n = 7
Confidence interval : xbar ± margin of error
Margin of Error = Tcritical * s/sqrt(n)
Degree of freedom (df) = n - 1 = 7 - 1 = 6
Hence Tcritical = 3.143
Margin of Error = 3.143 * 0.29/sqrt(6)
Margin of error = 0.37211
Lower boundary = (1.01 - 0.37211) = 0.63789
Upper boundary = (1.01 + 0.37211) = 1.38211
