A traveler is trying to determine the fastest way to travel from city A to city Z. The possible travel routes, with the time required for each segment, is shown below.
What is the shortest path and what is the shortest possible time to travel from A to Z? (Round your answer to the nearest whole number.)
Shortest Path Choices: A-B, B-E, E-Z ; A-C, C-Z ; A-B, B-D, D-Z
Answers
Answer:
Shortest Path : A-C, C-Z
Shortest possible time = 143
Step-by-step explanation:
P.S - The exact question is -
Given -
T1 = 38
T2 = 52
T3 = 63
T4 = 67
T5 = 91
T6 = 62
T7 = 64
To find - What is the shortest path and what is the shortest possible time to travel from A to Z ?
Proof -
Choices for shortest path is -
Choice 1 : A-B, B-E, E-Z ;
Choice 2 : A-C, C-Z ;
Choice 3 : A-B, B-D, D-Z
Now,
For Choice 1 : A-B, B-E, E-Z
Distance between A-B = T1 = 38
Distance between B-E = T4 = 67
Distance between E-Z = T7 = 64
So,
The distance = 38 + 67 + 64 = 169
Now,
For Choice 2 : A-C, C-Z
Distance between A-C = T2 = 52
Distance between C-Z = T5 = 91
So,
The distance = 52 + 91 = 143
Now,
For Choice 3 : A-B, B-D, D-Z
Distance between A-B = T1 = 38
Distance between B-D = T3 = 63
Distance between D-Z = T6 = 62
So,
The distance = 38 + 63 + 62 = 163
∴ By comparing we get
Shortest Path = A-C, C-Z
Shortest possible time = 143
The shortest path is A→C→Z and the shortest possible time is 143 units option second is correct.
It is given that the traveler is trying to determine the fastest way to travel from city A to city Z.
It is required to find the shortest path and the shortest possible time to travel from A to Z.
What is the shortest path?It is defined as the path in which all the sum of the path will be shortest in a weighted diagram known as the shortest path.
We have the time required to travel from A to B is T1 = 38 units
Similarly, for the path A to C is T2= 52 units
For the path B to D is T3= 63 units
For the path B to E is T4 = 67 units
For the path C to Z is T5 = 91 units
For the path D to Z is T6 = 62 units
For the path E to Z is T7 = 64 units
For the path A→B→E→Z
The total time required = T1+T4+T7
= 38+67+64 ⇒169 units.
For the path A→C→Z
The total time required = T2+T5
= 52+91 ⇒143 units.
For the path A→B→D→Z
The total time required = T1+T3+T6
= 38+63+62 ⇒ 163 units.
Thus, the shortest path is A→C→Z and the shortest possible time is 143 units option seconds is correct.

Step-by-step explanation:
Many businesses and organizations insist that official communications use professional-looking fonts, such as Times New Roman. Fonts characterized as less professional, such as Comic Sans, should be avoided. A student would like to determine if font choice makes a difference in the average grade on a typed response in English classes. There are currently four English classes available from which the student can collect data, and each class has a similar writing assignment. That the start of the assignment, students are randomly assigned a font, either times new Roman or comic sans, and then complete the assignment the teachers grade the assignment and the mean grade for each font is found.
What is the response variable in this experiment?
A the font used by each h student
B, the teachers grading the responses
C the grade received on each assignment
D the length of the student response on the assignment
Answers
Answer:
C.
Step-by-step explanation:
The response variable can be defined as those variables that are considered to be the focus of a question in research or experiment. It is also known as a dependent variable and is marked on the y-axis. The response variable is explained with the help of an explanatory variable, marked on the x-axis. The other names for response variables are y-variables or outcome variables.
In the given case, the response variable is the grade received on each assignment. The grades received by students on each assignment are the main focus of this research.
Therefore, option C is correct.
At Ralphs Italian Ices, 145 sundaes were sold in June. Sales were up 23% in July, How many sundaes were sold in July?
Answers
To calculate a percentage, we convert to a decimal by dividing by 100. So 23% = 0.23
145 x 0.23 = 33.35 This is how many more sundaes were sold in July than June. We need to add the 145 sold in June to the increased number to find July’s total.
145 + 33.35 = 178.35
You can’t sell .035/ roughly a third of a sundae, so we round to the whole number.

Answers
Answer:
If im not wrong, if every question is 2 points of 100 points in total means that are 50 questions, so if he gets 10 wrong then he would be losing 20 points which his final grade would be 80!
Answer:
Score with 10 questions wrong: 80
Score with x questions wrong: 100−2x
Step-by-step explanation:
each point is deducted by 2 pts and so, with 10 question, he got an 80.
100 is the availability of the points and 2x means which the points were lost
One method for straightening wire before coiling it to make a spring is called "roller straightening." The article "The Effect of Roller and Spinner Wire Straightening on Coiling Performance and Wire Properties" (Springs, 1987: 27–28) reports on the tensile properties of wire. Suppose a sample of 16 wires is selected and each is tested to determine tensile strength (N/mm2 ). The resulting sample mean and standard deviation are 2160 and 30, respectively. a. The mean tensile strength for springs made using spinner straightening is 2150 N/mm2 . What hypotheses should be tested to determine whether the mean tensile strength for the roller method exceeds 2150? b. Assuming that the tensile strength distribution is approximately normal, what test statistic would you use to test the hypotheses in part (a)? c. What is the value of the test statistic for this data? d. What is the P-value for the value of the test statistic computed in part (c)? e. For a level .05 test, what conclusion would you reach?
Answers
Answer:
We accept H₀, we don´t have enough evidence to claim that the procedure improves the tensile strength above the peviuos average
Step-by-step explanation:
Information:
μ = 2150
Sample size n = 16
Sample mean x = 2160
Sample standard deviation s = 30
a) Test Hypothesis
Null Hypothesis H₀ x = μ
Alternative Hypothesis Hₐ x > μ
b) If Tensile strength is approximately normal distribution we should use t-student statistic for testing the above hypothesis.
t(s) = ?? with df = n - 1 df = 15
c) t(s) = ( x - μ ) / s/√n
t(s) = ( 2160 - 2150 ) / 30/√16
t(s) = 10*4 / 30
t(s) = 1,33
d) In t-student we look for p-vale for 1,33 and df = 15
p-value = 0,1
e) If the level of significance is 0,05, then α/2 = 0,025
we compare p-value and level of significance
p-value 0,1 > 0,025
Then p-value is bigger than the significance level, we should accept H₀

Answers
Answer(In bold)/Step-by-step explanation:
Compute the probability that a randomly selected peanut M&M is not blue
P (blue) = 23%
P (blue)C = 1 - P(blue) = 100% - 23% = 77%
Compute the probability that a randomly selected peanut M&M is green or red.
P (green) = 15%
P (red) = 12%
P (green or red) = P(green) + P(red) = 27%
Compute the probability that three randomly selected peanut M&M’s are all yellow.
P (yellow) = 15%
(P(yellow))3 = 0.338%
There was replacement in the selection process.
If you randomly select six peanut M&M’s, compute that probability that none of them are brown.
P(brown) = 12%
P(brown)C = 1 - P(brown) = 100% - 12% = 88%
(P(brown)C)6 = 46.440%

Answer:
Jennifer would complete the job on her own in 5 hours.
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]
[tex]\Delta = b^{2} - 4ac[/tex]
Rates
The together rate is the sum of their separates rate.
We have that:
Jennifer takes x hours to complete the job on her own, so her rate is 1/x.
Carl needs 15 hours longer than Jennifer, that is, 15 + x hours, so his rate is 1/(15+x).
The together rate is 1/4. So
[tex]\frac{1}{4} = \frac{1}{x} + \frac{1}{15+x}[/tex]
[tex]\frac{1}{4} = \frac{15 + x + x}{x(15+x)}[/tex]
[tex]\frac{1}{4} = \frac{15 + 2x}{x(15+x)}[/tex]
Applying cross multiplication.
[tex]x^2 + 15x = 4(15 + 2x)[/tex]
[tex]x^2 + 15x = 60 + 8x[/tex]
[tex]x^2 + 7x - 60 = 0[/tex]
Quadratic equation with [tex]a = 1, b = 7, c = -60[/tex]. So
[tex]\Delta = 7^{2} - 4*1*60 = 289[/tex]
[tex]x_{1} = \frac{-7 + \sqrt{289}}{2} = 5[/tex]
[tex]x_{2} = \frac{-7 - \sqrt{289}}{2} = -12[/tex]
Since the time to complete the job has to be a positive value.
Jennifer would complete the job on her own in 5 hours.
