Answer:
Jesse will have $120.
Step-by-step explanation:
First you need to set up your equation. We know Jesse has $60 already and that he charges $15 per lawn. Your equation will look something like this:
15x+60=?
Then you plug in the 4 lawns he did:
15(4)+60=
Then you solve and get 120! :)
PS Parenthesis mean you are multiplying. Same thing as saying
15 x 4 + 60= 120

The given undirected, weighted graph consists of various nodes connected by edges with corresponding weights. To draw the graph, we represent each node as a vertex and connect them with edges labeled with their respective weights.
To find the minimal spanning tree (MST) on the 5 by 5 square of nodes, we need to select the subset of edges that connect all the nodes with the minimum total weight.
a) Drawing the weighted graph: Based on the given edge list, we draw the graph by representing each node as a vertex and connecting them with edges labeled with their corresponding weights. We consider the nodes A, B, C, D, ..., and draw the edges with the respective weights between the corresponding vertices.
b) Drawing the minimal spanning tree (MST): To find the MST on the 5 by 5 square of nodes, we need to select the subset of edges that connect all the nodes with the minimum total weight. Starting from any node, we choose the edge with the minimum weight to connect it to another node. We continue this process, ensuring that we do not form cycles and include all the nodes until we have connected all the nodes with the minimum total weight.
By considering the weights and following the process described above, we draw the minimal spanning tree on the 5 by 5 square of nodes, connecting them with the minimum weight edges.

A rancher planned to fence 6 1/2 acres of land to grow some experimental grasses. After he had finished fencing 4 3/4
acres of the land, it started snowing. How many acres of the land remained to be fenced?
Answer:
1 3/4 acres
Step-by-step explanation:
6 1/2 - 4 3/4 = the remaining acres to be fenced.
we can bring all numbers to "quarters" (1/4th) to be able to make that subtraction.
6 1/2 = 13/2 = 26/4
4 3/4 = 19/4
so, 26/4 - 19/4 = 7/4 = 1 3/4 acres still to be fenced.
Among 200 people, 150 either swim or jog or both. If 85 swim and 60 swim and jog, how many jog? Explain it
Answer:
5 people JUST jog
Step-by-Step Explanation:
150 PEOPLE
150-85=65 (85=swim)
65-60(swim/jog) =5 (jog)
THAT MEANS 5 PEOPLE JUST JOG
OR 65 PEOPLE JOG OVERALL
The number of people who jogs are 90.
We can solve this problem using the Rule of Inclusion/Exclusion.
The Rule of Inclusion/Exclusion states that if you want to find the number of elements in both sets, subtract the number of elements in the intersection from the sum of the number of elements in each set.
Therefore, in this problem, the number of people who jog is equal to the total number of people who either swim or jog, 150, minus the number of people who both swim and jog, 60, which is equal to 90 people.
Therefore, 90 people jog.

Assume that X is normally distributed with a mean m = $64. If P(X ³ $75) = 0.2981, then the standard deviation of X is approximately equal to
The standard deviation of X is approximately $20.07.
We can solve this problem by using the standard normal distribution and the z-score formula.
First, we need to standardize the variable X by subtracting the mean m and dividing by the standard deviation σ:
z = \(\frac{(X - m) }{σ}\)
We want to find the value of σ that makes P(X ≥ $75) = 0.2981. Using the standard normal distribution table, we can find the z-score corresponding to the area to the right of z:
P(Z ≥ z) = 0.2981
z = 0.546
Substituting this value of z and the given mean m, we get:
0.546 = ($75 - $64) /Ф
Solving for σ, we get:
σ = ($75 - $64) / 0.546
σ ≈ $20.07
Therefore, the standard deviation of X is approximately $20.07.

lines a and b are parallel. if the slope of line a is 1/4 what is the slope of line b?
Answer:
1/4
Step-by-step explanation:
we know that the lines A and B are parallel.
The term "parallel" implies that they will never meet each other, and to do so, the lines must have the same slope.
So the slope of line A is the same as line B (as for all parallel lines have the same slope)
So the slope of line B is also 1/4

Find the taylor series for f(x) centered at the given value of a. [assume that f has a power series expansion. do not show that rn(x) → 0. ] f(x) = ln x, a = 9
Taylor series is \(f(x) = ln2 + \sum_{n=1)^{\infty}(-1)^{n-1} \frac{(n-1)!}{n!(9)^{n}(x9)^{2} }\)
To find the Taylor series for f(x) = ln(x) centering at 9, we need to observe the pattern for the first four derivatives of f(x). From there, we can create a general equation for f(n). Starting with f(x), we have
f(x) = ln(x)
\(f^{1}(x)= \frac{1}{x} \\f^{2}(x)= -\frac{1}{x^{2} }\\f^{3}(x)= -\frac{2}{x^{3} }\\f^{4}(x)= \frac{-6}{x^{4} }\)
.
.
.
Since we need to have it centered at 9, we must take the value of f(9), and so on.
f(9) = ln(9)
\(f^{1}(9)= \frac{1}{9} \\f^{2}(9)= -\frac{1}{9^{2} }\\f^{3}(x)= -\frac{1(2)}{9^{3} }\\f^{4}(x)= \frac{-1(2)(3)}{9^{4} }\)
.
.
.
Following the pattern, we can see that for \(f^{n}(x)\),
\(f^{n}(x)=(-1)^{n-1}\frac{1.2.3.4.5...........(n-1)}{9^{n} } \\f^{n}(x)=(-1)^{n-1}\frac{(n-1)!}{9^{n}}\)
This applies for n ≥ 1, Expressing f(x) in summation, we have
\(\sum_{n=0}^{\infinite} \frac{f^{n}(9) }{n!} (x-9)^{2}\)
Combining ln2 with the rest of series, we have
\(f(x) = ln2 + \sum_{n=1)^{\infty}(-1)^{n-1} \frac{(n-1)!}{n!(9)^{n}(x9)^{2} }\)
Taylor series is \(f(x) = ln2 + \sum_{n=1)^{\infty}(-1)^{n-1} \frac{(n-1)!}{n!(9)^{n}(x9)^{2} }\)

Answer:
\(d=\frac{2w(c-2)}{5} \)
Step-by-step explanation:
The given formula is:
c=5d+4w/2w
We need to find d.
Multiply 2w on both sides, we get
c x 2w= 5d+4w/2w x 2w
2cw=5d+4w
Adding -4w on both sides, we get
2cw-4w=5d+4w-4w.
2cw-4w=5d
2w(c-2)=5d
Dividing by 5, we get
2w(c-2)/5 = 5d/5
2w(c-2)/5 = d
Hence the required formula with subject d is
\(d=\frac{2w(c-2)}{5} \)

A' = (1/2 * x₁, 1/2 * y₁)
B' = (1/2 * x₂, 1/2 * y₂)

What is triangle?
A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.
To find the image of triangle ABC after a dilation with center (0,0) and a scale factor of 1/2, we need to multiply the coordinates of each vertex by the scale factor.
Let's suppose that the coordinates of the vertices of the original triangle ABC are:
A = (x₁, y₁)
B = (x₂, y₂)
C = (x₃, y₃)
Then, the coordinates of the image of A, B, and C after the dilation are:
A' = (1/2 * x₁, 1/2 * y₁)
B' = (1/2 * x₂, 1/2 * y₂)
C' = (1/2 * x₃, 1/2 * y₃)
Therefore, the coordinates of the image of the triangle ABC after the dilation with center (0,0) and a scale factor of 1/2 are:
A' = (1/2 * x₁, 1/2 * y₁)

Step-by-step explanation:
The glycemic index (GI) is a rating system for foods containing carbohydrates. It shows how quickly each food affects your blood sugar (glucose) level when that food is eaten on its own. A random sample of 33 children were provided with a breakfast of low Gl foods on one day and high Gl foods on another. The two breakfasts contained the same quantities of carbohydrate, fat and protein. On each day a buffet lunch was provided, and the number of calories eaten at lunchtime were recorded. On the first day the children ate a low Gl breakfast and on the second day a high Gl breakfast. Let Hd be the true mean of the differences in calorie intake for a high Gl and a low GI breakfast, respectively. The researcher wants to conduct inference on Hd to determine whether the kind of breakfast eaten has an effect on mean calorie intake. The differences are calculated as calorie intake after high-GI breakfast minus calorie intake after low-GI breakfast. The sample mean of the differences of 63.543 calories, and the sample standard deviation of the differences was 153.
Briefly (in 1-2 sentences) explain why we must use inference procedures for paired data instead of inference procedures for independent random samples. (Note: We will read only the first up to 2 sentences of your answer, so it will not help you to write more than 2 sentences.)
Inference procedures for paired data are used when comparing two measurements on the same subjects or units, such as in this case where the calorie intake is measured for each child under two different breakfast conditions.
Paired data allows us to account for individual variability and potential confounding factors that may exist between subjects, resulting in more accurate and precise inference about the effect of the variable of interest (breakfast type) on the outcome (calorie intake).
Using inference procedures for independent random samples would not be appropriate in this scenario because it would not take into account the paired nature of the data.
Treating the measurements as independent would neglect the fact that each child serves as their own control, and the difference in calorie intake between the two breakfasts is the variable of interest. By pairing the measurements, we can better assess the specific effect of the breakfast type on calorie intake while controlling for individual differences within the sample.
