The weight of the soccer balls bought by the coach is 40.18 pounds. therefore, option a.40.18 is correct.
To determine the weight of the soccer balls the coach bought, we need
to analyze the given line plot. The line plot shows the weight of each of
the 11 soccer balls bought by the coach.
The first step is to find the scale of the line plot. In this case, the scale is
in pounds, and the plot ranges from 0 to 8 pounds. Each "x" on the plot
represents one soccer ball, and the height of the "x" shows the weight of
that ball in pounds.
To find the total weight of the soccer balls bought by the coach, we
simply need to add up the weights of all the balls. Looking at the line
plot, we can see that there are:
2 balls that weigh 1 pound each
1 ball that weighs 3 pounds
1 ball that weighs 2 pounds
1 ball that weighs 5 pounds
1 ball that weighs 3.7 pounds
1 ball that weighs 8 pounds
2 balls that weigh 4 pounds each
1 ball that weighs 8.48 pounds
Adding all these weights together, we get:
1 + 1 + 3 + 2 + 5 + 3.7 + 8 + 4 + 4 + 8.48 = 40.18 pounds
Therefore, the weight of the soccer balls bought by the coach is 40.18 pounds.

Triangle PQR is translated to triangle P'Q'R'.What are the co-ordinates of Q' and R'?
Triangle PQR is translated to triangle P'Q'R'. (-3,3) and (-1,1) are the co-ordinates of Q' and R'.
The co-ordinates of Q' and R' when triangle PQR is translated to triangle P'Q'R' are (-3,3) and (-1,1), respectively.
A translation is a type of transformation where a shape is moved from one position to another.
However, the shape is not rotated, resized, or reflected in a translation.
Instead, it is moved in a straight line from one position to another.
A translation in a two-dimensional plane is specified by a vector, which specifies the distance and direction of the translation.
The co-ordinates of Q' and R' when triangle PQR is translated to triangle P'Q'R' are (-3,3) and (-1,1), respectively.
To determine these co-ordinates, we can use the following steps:
Determine the vector of the translation.
To do this, we find the difference between the corresponding vertices of the two triangles.
Here, we can take PQ as the base.
So, P'Q' = QRQR
= PQP' = P + (-1,2)
= (-2,3)Q'
= Q + (-1,2)
= (-3,3)R'
= R + (-1,2)
= (-1,1).

How many lines can be formed in a cube please help tomorrow na ang deadline nito
In a cube, a total of 12 lines can be formed.
It has 8 vertices and 12 edges. In geometry, a line is a straight geometric figure that extends indefinitely in both directions. The lines in a cube are the straight lines that connect two vertices or edges of the cube. When two points are connected with a line, it creates an edge. In a cube, there are 12 edges. Each edge is shared by two faces, and the edges are the line segments that make up the sides of the cube.
Thus, the number of lines that can be formed in a cube is 12. When two or more lines meet at a point, it is called a vertex. A cube has eight vertices or corners. When a line is drawn between any two vertices of a cube, it is called a diagonal. In a cube, there are 12 diagonals. A diagonal is a straight line segment that connects two non-adjacent vertices of a polygon. So, the number of lines that can be formed in a cube is 12, which includes the 12 edges.

A spinner has five equal sections marked 1-5. What is the probability of not landing on four?
Answer: 4/5
Step-by-step explanation:
Five equal sides = 5
4 is just one side, so = 1
Not landing in 4 = 4/5
Answer: 4/5 or 80%
Step-by-step explanation:
Since the spinner has five equal sections, each numbered 1 through 5, the probability of landing on any particular number is 1/5.
To find the probability of not landing on 4, we need to add up the probabilities of landing on all the other numbers and subtract that sum from 1 (since the sum of all possible outcomes must equal 1).
The probability of landing on 4 is 1/5, so the probability of not landing on 4 is:
1 - 1/5 = 4/5
Therefore, the probability of not landing on 4 is 4/5 or 0.8, which is equivalent to an 80% chance.

What is percentage?In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. Percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.
Equation:The correct calculations to determine how much James will pay in total are:
First, we need to calculate how much 10% of $38.50 is:
10% of $38.50 = 0.1 × $38.50 = $3.85
So, James will receive a discount of $3.85.
To determine how much James will pay in total, we can use either of the following calculations:
A. James' total cost after the 10% discount would be: 38.5 - 0.9(38.5) = 38.5 - 34.65 = $3.85
B. The 10% discount on the total cost can be calculated as 0.1(38.5) = $3.85, which can be subtracted from the total cost to get James' final cost as 38.5 - 3.85 = $34.65
C. James' final cost after the 10% discount would be 1.1(38.5) = $42.35, which is not the correct answer as it does not take into account the discount.
D. James' total cost after the 10% discount would be: 0.9(38.5) = $34.65, which is the correct answer.
E. The calculation 0.1(38.5) = $3.85 represents the amount of the discount, and is not the final cost.

The sum of one-fifth of a non-negative integer and one-third of another non-negative integer is 1. What is the maximum value of the sum of these 2 non-negative integers.
Answer: 7, and it occurs when x = 5 and y = 2
Step-by-step explanation:
1/5 x + 1/3 y = 1 (Equation 1)
x + y = ? (Equation 2)
We want to find the maximum value of x + y, so we need to maximize each of the variables x and y subject to the constraint given in Equation 1.
To solve for one of the variables, we can isolate it in terms of the other variable. Let's solve for y:
1/5 x + 1/3 y = 1
1/3 y = 1 - 1/5 x
y = 3(1 - 1/5 x)
Now we can substitute this expression for y into Equation 2:
x + y = x + 3(1 - 1/5 x)
Expanding the expression, we get:
x + y = x + 3 - 3/5 x
x + y = 3 + 2/5 x
So we can see that x + y is a linear function of x with slope 2/5 and y-intercept 3. To maximize x + y, we want to maximize x. However, x is a non-negative integer, so the maximum value of x occurs when x = 5 (since any larger value would result in a fraction in the expression for y).
Therefore, the maximum value of x + y is:
x + y = 3 + 2/5 x
x + y = 3 + 2/5 (5)
x + y = 5 + 2
x + y = 7
So the maximum value of the sum of these two non-negative integers is 7, and it occurs when x = 5 and y = 2.

Find an equation for the number of fish P(t) after t years.
How many years will it take for the population to increase to 3050
In light of this, it will take roughly 2.25 years for the populace to reach 3050,that shows growth rate. The equation to calculate the number of fishes in a pond after t years would be equal to t = -ln (0.12125) / r
What is the growth rate?The logistic development model can be used to calculate an equation for the growth rate of fish P(t) after t years:
Where[tex]: P(t) = K / (1 plus A e(-rt))[/tex]
[tex]r[/tex]= growth rate, where[tex]K =[/tex] carrying capacity [tex]= 6100 A =[/tex] starting population[tex]= 500[/tex]
T equals time in years
Using the given data, we can determine the increase rate:
In the first year, the quantity of fish increased from[tex]500 to 740:[/tex]
[tex]740 = 6100 / (1 + A e^(-r1))[/tex]
We arrive at [tex]A e(-r*1) = 8.24324[/tex] after solving for [tex]A e(-r).[/tex]
Given that P(t) must lie half way between A and K in order for there to be a maximal growth rate, the carrying capacity is [tex]6100:[/tex]
[tex]3050 = (6100 + 500) / 2 = 3300[/tex]
As a result, if [tex]P(t) = 3300,[/tex] we have:
[tex]3300 = 6100 / (1 + A e^(-rt))[/tex]
We arrive at [tex]A e(-rt) = 1.84848[/tex] after solving for [tex]A e(-rt).[/tex]
The following is the result of substituting the numbers of [tex]A e(-r*1)[/tex] and [tex]A e(-rt)[/tex] into the equation for P(t):
We can put into an expression and solve for t to determine how long it will take for the population to reach [tex]3050:[/tex]

[tex]e(-rt) = 0.12125 -rt = ln = 1 + 8.24324 e(-rt) = 2(0.12125)[/tex]
[tex]t = -ln(0.12125) / r[/tex]
Although we are unsure of r's precise value, we do know that [tex]A e(-rt) = 1.84848.[/tex]
at[tex]t = 3300, P(t).[/tex] When we enter these numbers into the solution, we obtain:
[tex]1.84848 = A e^(-r1)[/tex]
[tex]A = 1.84848 / e^(-r1)[/tex]
We obtain the following equation for t by substituting this value of A:[tex]t = -ln(0.12125) / r t = -ln(0.12125) / ln(1.84848 / e(-r*1))[/tex]
The precise value of r is not required to provide an answer, but we can solve for it using a numerical approach like trial and error or a graphing method.
The logistic development model can be used to calculate an equation for the quantity of fish P(t) after t years:
Where: [tex]P(t) = K / (1 plus A e(-rt))[/tex]
r = growth rate, where K = carrying capacity =[tex]6100 A[/tex] = starting population [tex]= 500[/tex]

Using the given data, we can determine the increase rate:
In the first year, the quantity of fish increased from 500 to 740:

We arrive at A e(-r*1) = 8.24324 after solving for A e(-r).
Given that P(t) must lie half way between A and K in order for there to be a maximal growth rate, the carrying capacity is 6100:
[tex]3050 = (6100 + 500) / 2 = 3300[/tex]
As a result, if P(t) = 3300, we have:

The Greeks believed that all constructions could be made with only a compass and straightedge, but some constructions were more difficult than others. In fact, they were able to make remarkable geometric constructions using only these two tools, such as trisecting an angle, duplicating a cube, and constructing a regular pentagon. However, in the 19th century, the discovery of new mathematical methods showed that some constructions, like squaring the circle, were actually impossible to complete with just a compass and straightedge.

Answer:
[tex]A = 212.1 \text{ cm}^2[/tex]
Step-by-step explanation:
We can identify the bases of the trapezoid as:
9cm and 21.3 cm
(notice how they are parallel)
We know the height is 14 cm.
Using these values, we can solve for the trapezoid's area.
[tex]A = \dfrac{1}{2}(b_1 + b_2) \cdot h[/tex]
↓ plugging in the values
[tex]A = \dfrac{1}{2}(9 + 21.3) \cdot 14[/tex]
↓ simplifying the parentheses
[tex]A = \dfrac{1}{2}(30.3) \cdot 14[/tex]
↓ multiplying 14 and (1/2)
[tex]A = 7 \cdot 30.3[/tex]
↓ multiplying
[tex]A = 212.1 \text{ cm}^2[/tex]

Therefore, f(11) can either be -16 or 20, depending on whether we use the recursive or explicit rule.
What is graph?In mathematics, a graph is a visual representation of the relationship between two or more variables. It is a collection of points (or vertices) that are connected by lines or curves (called edges) to show the relationships between them. Graphs are commonly used in many different fields of study, including mathematics, science, engineering, and social sciences, to represent and analyze data, identify patterns, and make predictions.
Here,
We can observe that this is an arithmetic sequence, where each term is obtained by adding a constant difference to the previous term. To find the recursive rule, we can use the formula:
f(n) = f(n-1) + d
where f(n-1) is the previous term, d is the common difference, and f(n) is the nth term. Using the given values, we can find that the common difference is d = -6. So the recursive rule for the sequence is:
f(1) = 80
f(n) = f(n-1) - 6
To find the explicit rule, we can use the formula:
f(n) = a + (n-1)d
where a is the first term, d is the common difference, and n is the term number.
Using the first two terms, we can find that:
a = 80
d = -6
So the explicit rule for the sequence is:
f(n) = 80 - 6(n-1)
To find f(11), we can substitute n = 11 into either the recursive or explicit rule:
Using the recursive rule:
f(11) = f(10) - 6
= (f(9) - 6) - 6
= (f(8) - 12) - 6
= (f(7) - 18) - 6
= (f(6) - 24) - 6
= (f(5) - 30) - 6
= (20 - 30) - 6
= -16
Using the explicit rule:
f(11) = 80 - 6(11-1)
= 80 - 6(10)
= 20

Complete the inequality so that it represents the whole-number values that side a could be to create a triangle.
The possible whole-number values of 'a' that satisfy the triangle inequality are 2, 3, 4, 5, and 6.
What is triangle?A triangle is a three-sided polygon with three vertices. The triangle's internal angle, which is 180 degrees, is constructed.
To create a triangle with sides a, b, and c, the sum of the lengths of any two sides must be greater than the length of the third side. This can be represented by the triangle inequality:
a + b > c
a + 6 > 7 (substituting the given values for b and c)
a > 1
b + c > a
6 + 7 > a
13 > a
a + c > b
a + 7 > 6
a > -1
Since the length of a cannot be negative, the inequality can be simplified to:
a > 1
Therefore, to create a triangle with side lengths of 7, 6, and some whole number value for a, a must be greater than 1. The possible whole-number values of 'a' that satisfy the triangle inequality are 2, 3, 4, 5, and 6.

this poll was shown in july 2018. it shows a moe (margin of error) of 3%, or 0.03. it shows poll results of issues that millennials care about most: jobs/economy 25%, immigration 17%, healthcare 16%, education 16%, environment 12%. what is the upper limit of the confidence interval for the proportion of millennials that care about immigration? write your answer as a proportion (decimal) and not as a percent. do not round.
The upper limit of the confidence interval for the proportion of millennials that care about immigration is 0.20.
In order to find the upper limit of the confidence interval for the proportion of millennials that care about immigration,
we first need to calculate the confidence interval using the margin of error (MOE) and sample proportion.
The formula to find the confidence interval is given by:
Confidence Interval = Sample Proportion ± Margin of Error (MOE)
Where Sample Proportion = Poll Result / 100
Let's first find the Sample Proportion of millennials that care about immigration.
Sample Proportion = Poll Result / 100= 17 / 100= 0.17
Now let's calculate the confidence interval using the MOE.
Confidence Interval = Sample Proportion ± Margin of Error (MOE)
Upper Limit of Confidence Interval = Sample Proportion + MOE= 0.17 + 0.03= 0.20
Therefore, the upper limit of the confidence interval for the proportion of millennials that care about immigration is
0.20.
