Answer:
(x, y) is transformed into (y, -x)
This is the last option (option I) in the list of possible answers.
Step-by-step explanation:
Notice the transformation in the point you picked: (-6,4), which from this coordinates change into the point (4,6) after the rotation about the origin.
Notice that the value "4" which was the original "y" value of the point, now became the "x" value for the transformed point.
So so far we have: (..., y) transformed into (y, ...)
now,notice that the value "-6" which was the original x=value for the point, after the transformation appeared in the new "y" position, and with the signed reversed (from -6 into +6), so it became the new x value but with opposite sign.
Then we can complete how the transformation can be represented:
(x, y) is transformed into (y, -x)

Three fair coins are flipped. What is the probability that at least 2 of them come up heads?
Answers
Answer:
The probability that atleast 2 of them come up heads is 0.5∴ P(A)=0.5Step-by-step explanation:
Given that three fair coins are flipped.
To find the probability that at least 2 of them come up heads:Sample space for the given event is
[tex]S={\{HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}\}[/tex]
∴ n(S)=8Let A be the events of getting atleast 2 Heads and is given by
A = {HHH, HHT, HTH, THH}
∴ n(A)=4Probability of Getting atleast 2 Heads in 3 Coin Tosses is
[tex]P(A)=\frac{n(A)}{n(S)}[/tex]
[tex]P(A)=\frac{4}{8}[/tex]

A cylindrical 2014-t6 aluminum alloy bar is subjected to compression-tension stress cycling along its axis; results of these tests are shown in fig. 1. if the bar diameter is 12.0 mm, calculate the maximum allowable load amplitude (in newtons) to ensure that fatigue failure will not occur at 107 cycles.
Answers
Complete part of Question:
Assume a factor of safety of 3.0
The Maximum stress versus logarithm of the number of cycles to fatigue failure curve for 2014-T6 Aluminium bar is attached to this solution
Answer:
The maximum allowable load amplitude is 6403.33 N
Step-by-step explanation:
diameter of the bar, d = 12 mm
d = 0.012 m
Cross sectional area of the bar, A = πd²/4
A = π*0.012²/4
A = 0.000113 m²
From the Maximum stress versus logarithm of the number of cycles to fatigue failure for 2014-T6 Aluminium bar attached to this solution;
At 10⁷ cycles, Maximum stress, S = 170 MPa
S = 170 * 10⁶ Pa
Factor of safety, N = 3.0
The tensile stress is given by the formula:
[tex]\sigma = S/N\\\sigma = \frac{170 * 10^{6} }{3} \\\sigma = 56.67 * 10^{6} N/m^{2}[/tex]
The tensile stress is also given by:
[tex]\sigma = F/A\\\sigma = F/0.000113[/tex]
F/0.000113 = 56.67 * 10⁶
F = 56.67 * 10⁶ * 0.000113
F = 6403.33 N
The maximum allowable load amplitude is 6403.33 N
Answer:
The maximum allowable load amplitude is 6408.85 Newtons
Step-by-step explanation:
Assume a factor of safety N = 3.0
From the graph attached, the maximum stress the cylindrical 2014-t6 aluminum alloy bar is subjected to is S = 170MPa
diameter d = 12.0 mm = 12*10^-3 m
area A
S = F/A
But A = (Π* d²)/4
S = 4F/(Π*d²)
By incorporating factor of safety N
S/N = 4F/(Π*d²)
F = SΠd²/4N
F = {170*10^6 *Π *(12*10^-3)}/4*3.0
F = 76906.19/12 = 6408.85 Newtons

A set of data with 100 observations has a mean of 267. There are six outliners in the data set, which have a mean of 688 if the six outliners are removed, what is the mean of the new data set?
Answers
Answer:
272.04
Step-by-step explanation:
We must make a weighted average, as follows:
Each mean will have its weight, which would be the number of observations, therefore, the initial mean has a weight of 100.
And the final mean that we do not know its value but if its 94 (100 - 6) and the other mean that it is 688 and its weight is 6, we have the following equality:
100 * 297 = 688 * 6 + 94 * x
x would be the final mean, solving:
x = (29700 - 4128) / 94
x = 272.04
average after removing those 6 is 272.04

Dr. Don offers a tutoring service for college students. He charges $40 as a fixed rate for the first hour plus $20 for each additional hour. What is the minimum and maximum number of hours of tutoring a student can get if he or she can afford to spend between $140 and $200? (Express your answer as an inequality)
Answers
Answer: 6 ≤ h ≤ 9
Step-by-step explanation:
Hi, since He charges $40 as a fixed rate for the first hour plus $20 for each additional hour, the cost of the tutoring service is equal to the fixed rate(40) plus, the product of the additional hours (h-1) and the cost per additional hour (20).
40+20(h-1)
40+20h-20
20+20h
Since a student can spend between $140 and $200, the previous expression must be greater o equal than 140, and less or equal than 200.
140≤20+20h≤200
Subtracting 20
140-20 ≤20-20+20h ≤200-20
120 ≤ 20h ≤ 180
Dividing by 20
120/20 ≤ 20h/20 ≤ 180/20
6 ≤ h ≤ 9
Final answer:
The minimum and maximum number of hours of tutoring a student can get if they can spend between $140 and $200 is 5 and 8 hours, respectively.
Explanation:
To determine the minimum and maximum number of hours of tutoring a student can get, we need to set up an inequality based on the pricing information provided. Let's denote the number of additional hours beyond the first hour as x.
The total cost of tutoring will be $40 for the first hour plus $20x for each additional hour. The student can afford to spend between $140 and $200, so the inequality is:
140 ≤ 40 + 20x ≤ 200
To find the solution, we need to isolate x. First, subtract 40 from all parts of the inequality:
100 ≤ 20x ≤ 160
Next, divide all parts of the inequality by 20:
5 ≤ x ≤ 8
Therefore, the minimum number of hours is 5 (including the first hour) and the maximum number of hours is 8 (including the first hour).

Ally slice 32 kg of watermelon for a party she divided the watermelon slices equally between 8 large bowls how many gams of watermelon did ally put in each bowl
Answers
4000 g
Step-by-step explanation:
32 kg means 32000 g of watermelon
divided into 8 bowls
grams of watermelon in each bowl are 32000÷8 = 4000 g
Ally put 4,000 grams of watermelon in each bowl.
Explanation:
To find out how many grams of watermelon Ally put in each bowl, we need to divide the total weight of the watermelon slices by the number of bowls. Ally sliced 32 kg of watermelon and divided it equally between 8 large bowls. To convert kg to grams, we multiply by 1000. So, the total weight of watermelon in grams is 32,000 grams. To find out how many grams of watermelon went into each bowl, we divide the total weight by the number of bowls: 32,000 grams / 8 bowls = 4,000 grams.

There are 32 packages of ground meat for sale.
Explanation:To find the number of packages of ground meat for sale, we need to divide the total pounds of meat available by the weight of each package.
Given that each package weighs 3÷4 pounds and the shop has 24 pounds of meat available, we can divide 24 by 3÷4 to find the number of packages.
Dividing 24 by 3÷4 is the same as multiplying 24 by the reciprocal of 3÷4, which is 4÷3. Therefore, there are 24 × (4÷3) = 32 packages of ground meat for sale.

Which of the following is NOT true when testing a claim about a proportion? Choose the correct answer below. A.

B. When testing claims about population proportions, the traditional method and the P-value method are equivalent in the sense that they always yield the same result. C. A conclusion based on a confidence interval estimate will be the same as a conclusion based on a hypothesis test. D. If you want to test a claim about population proportions, use the P-value method or the classical method of hypothesis testing.
Answers
Answer: C. A conclusion based on a confidence interval estimate will be the same as a conclusion based on a hypothesis test.
Explanation: The One-Sample Proportion Test is used to assess whether a population proportion (P1) is significantly different from a hypothesized value (P0). This procedure calculates sample size and statistical power for testing a single proportion using either the exact test or other approximate z-tests.
To write a null hypothesis, first, start by asking a question. Rephrase that question in a form that assumes no relationship between the variables. In other words, assume a treatment has no effect. Write your hypothesis in a way that reflects this.
A null hypothesis is a hypothesis that says there is no statistical significance between the two variables. It is usually the hypothesis a researcher or experimenter will try to disprove or discredit. An alternative hypothesis is one that states there is a statistically significant relationship between two variables.

Step-by-step explanation:
The diameter of the wheel, d= 60 ft
We know the perimeter of the wheel is,

= 3.1416*60
= 188.496 ft
Wheel travel for 5 minutes. So the wheel travel,
= 5*60
= 300 sec
The wheel rotates in every 15 seconds. So the wheel rotates,
= 300/15
= 20 times
In one rotation, the wheel travels its perimeter. so is 5 minutes it travels,
= 188.496*20
