Graph XY with endpoints X ( -4 , 3 ) and Y ( -2 , 1 ) and its image after the composition of a translation along < 1, 0 > and a rotation 90 clockwise about the origin .
HELP
The graph of the points are,
X = (3, 3)
Y = (1, 1)
Now, We can apply the given transformation of a translation along <1, 0> and a rotation of 90 degrees clockwise about the origin.
Here, The translation along <1, 0> means that to move every point on the graph 1 unit to the right.
And, The rotation of 90 degrees clockwise about the origin means to rotate every point 90 degrees in the clockwise direction around the origin, which is the point (0,0) on the plane.
So, for transform the line segment XY, the translation by adding 1 to the x-coordinate of each point.
Hence,. We get;
X = (-3, 3)
Y = (-1, 1).
Next, we can apply the rotation by using the formula:
(x', y') = (xcosθ + ysinθ, -xsinθ + ycosθ)
where (x, y) are the coordinates of the original point, (x', y') are the coordinates of the transformed point, and θ is the angle of rotation (in radians).
For rotating 90 degrees clockwise, we can substitute θ = -π/2 (negative because we are rotating clockwise) into the formula to obtain:
(x', y') = (y, -x)
So, to transform point X (-3,3), we have:
(x', y') = (y, -x) = (3,3)
And to transform point Y (-1,1), we have:
(x', y') = (y, -x) = (1,1)
Thus, The graph of the points are,
X = (3, 3)
Y = (1, 1)

The diagram shows two right-angled triangles that share a common side. 6 10. Show that x is between 11 and 12.
We have two right-angled triangles that share a common side, with side lengths 6 and 10. Let's label the sides of the triangles as follows:
Triangle 1:
Side adjacent to the right angle: 6 (let's call it 'a')
Side opposite to the right angle: x (let's call it 'b')
Triangle 2:
Side adjacent to the right angle: x (let's call it 'c')
Side opposite to the right angle: 10 (let's call it 'd')
Using the Pythagorean theorem, we can write the following equations for each triangle:
Triangle 1:\(a^2 + b^2 = 6^2\)
Triangle 2: \(c^2 + d^2 = 10^2\)
Since the triangles share a common side, we know that b = c. Therefore, we can rewrite the equations as:
\(a^2 + b^2 = 6^2\\b^2 + d^2 = 10^2\)
Substituting b = c, we get:
\(a^2 + c^2 = 6^2\\c^2 + d^2 = 10^2\)
Now, let's add these two equations together:
\(a^2 + c^2 + c^2 + d^2 = 6^2 + 10^2\\a^2 + 2c^2 + d^2 = 36 + 100\\a^2 + 2c^2 + d^2 = 136\)
Since a^2 + 2c^2 + d^2 is equal to 136, we can conclude that x (b or c) is between 11 and 12

4. [-/7.14 Points] DETAILS LARPCAL
The angle (in radians) between vectors u and v is approximately 1.66 radians, rounded to two decimal places.
To find the angle between two vectors, we can use the dot product formula and the magnitudes of the vectors. Let's calculate the angle between vectors u and v:
Given:
u = 4i - 6j
v = 5i + 4j
Step 1: Calculate the dot product of u and v.
The dot product of two vectors u and v is given by:
u · v = |u| |v| cosθ
where |u| and |v| are the magnitudes of vectors u and v, respectively, and θ is the angle between them.
To calculate the dot product, we multiply the corresponding components of u and v and sum them:
u · v = (4 * 5) + (-6 * 4) = 20 - 24 = -4
Step 2: Calculate the magnitudes of vectors u and v.
The magnitude of a vector is given by:
|u| = √(u₁² + u₂²)
For vector u:
|u| = √((4)² + (-6)²) = √(16 + 36) = √52 ≈ 7.21
For vector v:
|v| = √((5)² + (4)²) = √(25 + 16) = √41 ≈ 6.40
Step 3: Calculate the angle θ.
Using the dot product formula mentioned earlier, we have:
-4 = (7.21)(6.40)cosθ
Solving for cosθ:
cosθ = -4 / (7.21 * 6.40) ≈ -0.086
To find θ, we can take the inverse cosine (arccos) of cosθ:
θ ≈ arccos(-0.086) ≈ 1.66 radians

Cabs pass your workplace according to a Poisson process with a mean of five cabs per hour. Suppose that you exit the workplace at 6:00 pm. Determine the following: (a) Probability that you wait more than 10 minutes for a cab. (b) Probability that you wait fewer than 20 minutes for a cab. (c) Mean number of cabs per hour so that the probability that you wait more than 10 minutes is 0. 1
a) The probability of waiting more than 10 minutes for a cab is 0.303 or approximately 30.3%.
b) The probability of waiting fewer than 20 minutes for a cab is 0.726 or approximately 72.6%.
b) The mean number of cabs per hour that we need to have a probability of waiting more than 10 minutes for a cab of 0.1 is 7.88.
(a) The probability of waiting more than 10 minutes for a cab can be calculated using the Poisson distribution formula. Let's denote the average rate of cabs passing by as λ. Since the mean is given as five cabs per hour, we can set λ = 5. We need to find the probability of waiting more than 10 minutes, which is equivalent to waiting for 1/6 of an hour. We can use the Poisson distribution formula to calculate this probability:
P(X > 0.1667) = 1 - P(X ≤ 0.1667) = 1 -\(e^{-\lambda t}\)Σ(k=0 to ⌊λt⌋) (λt)ˣ / k!
where X is the number of cabs passing by in 1/6 of an hour, t = 1/6, λ = 5, and ⌊λt⌋ denotes the floor function of λt. Plugging in the values, we get:
P(X > 0.1667) = 1 - P(X ≤ 0.1667) = 1 - \(e^{-5(1/6)}\)Σ(k=0 to ⌊5(1/6)⌋) (5(1/6))ˣ / k!
= 1 - \(e^{-0.833}\)Σ(k=0 to 0) (0.833)ˣ / k!
= 0.303
(b) The probability of waiting fewer than 20 minutes for a cab can also be calculated using the Poisson distribution formula. We need to find the probability of waiting for 1/3 of an hour since 20 minutes is equivalent to 1/3 of an hour. Using the same formula as above, we get:
P(X ≤ 0.333) = \(e^{5(1/3)}\)Σ(k=0 to ⌊5(1/3)⌋) (5(1/3))ˣ / k!
= 0.726
(c) Finally, to find the mean number of cabs per hour so that the probability of waiting more than 10 minutes is 0.1, we need to solve for λ in the Poisson distribution formula:
P(X > 0.1667) = 1 - \(e^{-\lambda(1/6)}\)Σ(k=0 to ⌊λ(1/6)⌋) (λ(1/6))ˣ / x! = 0.1
Using trial and error or a numerical solver, we can find that the value of λ that satisfies this equation is approximately 7.88.

We are 98% confident that the proportion of obese clients losing weight under strategy 1 is between 13% less and 9% more than the proportion of obese clients losing weight under strategy 2. D. If samples were repeatedly drawn from the same populations under the same circumstances, the true population difference (p1 - p2) would be between -0.13 and 0.09 98% of the time. E. There is a 98% probability that the proportion of obese clients losing weight under strategy 2 is between 13% less and 9% more than the proportion of obese clients losing weight under strategy 1.
The correct interpretation of the given confidence interval is C. We are 98% confident that the proportion of obese clients losing weight under strategy 1 is between 13% less and 9% more than the proportion of obese clients losing weight under strategy 2.
The confidence interval is given as (-0.13, 0.09), which represents the range within which the true difference in proportions (p1 - p2) is likely to fall with a confidence level of 98%.
The negative value of -0.13 indicates that the proportion of obese clients losing weight under strategy 1 may be 13% less than the proportion under strategy 2.
The positive value of 0.09 indicates that the proportion of obese clients losing weight under strategy 1 may be 9% more than the proportion under strategy 2.
Since the confidence interval includes both positive and negative values, it suggests that the true difference in proportions could be either positive or negative.
The confidence level of 98% means that if we were to repeat the study and construct 100 different confidence intervals, about 98 of those intervals would capture the true difference in proportions (p1 - p2).
Therefore, we can conclude that we are 98% confident that the proportion of obese clients losing weight under strategy 1 is between 13% less and 9% more than the proportion of obese clients losing weight under strategy 2.

On a certain standardized test, each correct answer is worth 1 point, each incorrect answer is worth 4 1 - point, and each blank answer is worth 0 points. The final score is obtained by multiplying the point score by 10 and rounding to the nearest 10 points. If a student answered all 50 questions and received a score of 450, what was the difference between the number of correct and incorrect answers
The difference between the number of correct and incorrect answers is 34.
To find the difference between the number of correct and incorrect answers, we first need to determine the number of correct answers. We know that the point score is obtained by dividing the final score by 10. In this case, the point score is 45. Since each correct answer is worth 1 point, the number of correct answers is equal to the point score. Therefore, the student answered 45 questions correctly.
Next, we need to find the number of incorrect answers. Each incorrect answer is worth 4 1-point, so we divide the point score by 4. In this case, 45/4 equals 11.25.
Rounding to the nearest whole number, we get 11. Therefore, the student answered 11 questions incorrectly.
Finally, we calculate the difference between the number of correct and incorrect answers by subtracting the number of incorrect answers from the number of correct answers: 45 - 11 = 34.
Thus, the difference between the number of correct and incorrect answers is 34.
