Which of the following transformations does not
preserve congruence?
F. (x,y) → (-x, -Y)
G. (x, y) = (-y, -x)
H. (x, y) = (x + 9.y + 9)
J. (x,y) → (9x, 9y)
Answer:
(9x, 9y) dilation
Step-by-step explanation:
(9, 9y) is the answer because F is 180 degrees rotations, G is not real, H is translations, and J is dilations and dilations is multiplying which makes the transformation non congruent.

A study was commissioned to find the mean weight of the residents in a certain town. The study examined a random sample of 132 residents and found the mean weight to be 162 pounds with a standard deviation of 35 pounds. At the 95% confidence level, find the margin of error for the mean, rounding to the nearest tenth
Answer: 6.1
We are 95% confident that the true mean weight of the population is within 6.1 pounds of the sample mean 162.
At the 95% confidence interval, the margin of error for the mean is 6.1 pounds
What is margin error?The margin of error is "a statistic expressing the amount of random sampling error in the results of a survey".
According to the question,
Number of random samples (n) = 132 residents
Mean of weight of random samples (x⁻)= 162
Standard deviation of random samples (σ)= 35 pounds
In order to find at the 95% confidence interval, the margin of error for the mean.
Margin error = z (σ/√n)
The critical region 95% confidence interval under normal curve is 1.96.
= 1.96 (35/√132)
=1.96(35/11.48)
=1.96(3.0488)
= 5.9708636 ≈ 6.1 pounds
Hence, at the 95% confidence interval, the margin of error for the mean is 6.1 pounds.

MARK ME BRAINLIEST PLZZZZZZZZZzzzzzzzzzzzzzzzzzzzzzzzzAccording to a survey of workers, 5/25 of them walk to work, 1/25 bike, 4/25 carpool, and 15/25 drive alone. What percent of workers walk or bike to work?
Answer: 24%
Step-by-step explanation:
First add up the proportion of people who walk to work and those who bike as well. This will show the proportion of people who walk or bike to work.
This is:
= 5/25 + 1/25
= 6/25
Then convert this to a percentage:
= 6/25 * 100
= 24%

Find the measure of the arc or angle indicated.
Answer:
C
Step-by-step explanation:
Let solve for x
[tex]110 + 16x - 6 + 12x + 4[/tex]
[tex]28x + 108 = 360[/tex]
[tex]28x = 252[/tex]
[tex]x = 9[/tex]
Angle F is a inscribed angle that is intercepted by arc HG so
Angle F is half of Arc HG
Arc HG=

so Angle F is

Answer:
I think it's 45 degrees
Step-by-step explanation:
<c is 90 degrees and the interior of every triangle is 180 degrees so then we subtract 90 from 180 which is 90 so we divide 90 by two since b and a seem to be equal which is 45 degrees.

A store offers a discount of 40%. The discount price of a shirt is $42 . What is the regular price?
Answer:
$70 is the regular price of the shirt.
Step-by-step explanation:
One way in which to find the regular price here is to write the equation
0.60s = $42. A 40% discount is reflected in 100% - 40%, or 1.00 - 0.40, which comes out to 0.60.
If 0.60s = $42, then the regular price of the shirt is
s = ($42)/0.60 = $70
Answer:
$70.00

Answer:
1. 4 2. 2 3. Does not exist 4. Does not exist 5. 3
Step-by-step explanation:
1. This is the limit as x approaches 2 from the left. That means that x "sneaks up" on 2, but from the left (ironically moving right). As x does that, the graph rises, heading for 4 (even though the point is "empty"). The limit is 4. See attached image 1
2. Let x sneak up on 2 from the right (so moving left towards 2). As x does that, the graph falls, heading for the y-value 2. The limit is 2. See image 2.
3. This limit (two-sided) does not exist because the one-sided limits had different values.
4. This limit does not exist, either. The limit as x approaches 0 from the left is 4. The limit as x approaches 0 from the right is 0. These are different, so the two-sided limit is not defined.
5. g(2) = 3, where the solid dot is. It's the value of the function at x=2.

Answer:
x=52
Step-by-step explanation:
vertical angles are congruent so that means the angle measures are the same
so, you can set up this equation:
156=3x
and solve as follows:
156=3x
/3 /3
52=x
To prove that x=52 you can input 52 as x in the equation
156=3(52)
156=156
