Chareese reflects figure RSUT over the y-axis and then rotates the reflected figure 180° about the origin, resulting in figure A. She states that RSUT ≅ ZYWX. Which best describes the accuracy of her congruency statement?
A: Accurate. A reflection will change the direction the vertices trace around the figure. A rotation preserves the change.
B: Accurate. A reflection preserves the direction the vertices trace around the figure. A rotation changes that direction.
C: Inaccurate. The correct congruency statement is RSUT ≅ ZXWY
D: Inaccurate. The correct congruency statement is RSUT ≅ XWYX
Answer:
B
Step-by-step explanation:
the direction of the vertices is still as it is, but when u rotate is 180 degree, the direction of the points changes. This is the same as reflecting the image over the x-axis.
Answer:
B
Step-by-step explanation:
the direction of the vertices is still as it is, but when u rotate is 180 degree, the direction of the points changes. This is the same as reflecting the image over the x-axis.

A large bag contains 16 red, 48 blue, and 16 green marbles. Each student in Mrs. Wynn's class randomly selects a marble, records the color, and then puts the marble back into the bag. Mrs. Wynn then reports the total number of red, blue, and green marbles selected by the entire class. Which of these statements are true? Choose all that are correct. A. Theoretically, the probability of selecting one red marble from this bag is 0.20. B. If the total number of red marbles selected is not equal to the total number of green marbles selected, then there was a mistake in selecting the marbles or recording the data. C. If there are 30 students in the class, the total number of blue marbles selected should be about 18 but may be more or less. D. If a student does not return his or her marble to the bag before the next student selects his or her marble, the theoretical probability of selecting a blue marble may be different for the next student. E. It is possible that every student selects a green marble.
Answer:
It may be D. If a student does not return his or her marble to the bag before the next student selects his or her marble, the theoretical probability of selecting a blue marble may be different for the next student. because it would be the most logical response in this case

(Find the Probability Question)
Choose 2 girls from a class of 12 boys and 8 girls.
Step-by-step explanation:
what should be the question ?
how many different pairs of 2 girls can you pick out of 8 ?
what is the probability that a specific girl is in the picked pair ?
or is it : if you pick randomly 2 students from the class, what is the probability to have picked 2 girls ?
and there are more options.
but I assume the problem is the picking randomly 2 students.
so, it is 20 students (12 + 8). if we pick 1 student, we have a chance of 12/20 = 3/5 to pick a boy, and a chance of 8/20 = 2/5 to pick a girl.
in our experiment we pick 2 students in a row without returning the first pick into the main pool.
the probabilty for the first pick to be a girl is, as mentioned, 2/5 or 0.4.
for the second pick we have only 7 out of 19 choices to pick a girl. so, the probability to pick a girl now is 7/19.
the combination of both (non-overlapping) probabilities is done via multiplication, and the probabilty to pick 2 girls is :
2/5 × 7/19 = 2×7 / 5×19 = 14/95 = 0.147368421...
Peter has a unique computer. The screen of the computer is a square and measures twelve inches. What is the area of the entire computer screen?
A. 144 in
B. 124 in
C. 54 in
D. 48 in
Answer:
A. 144 in
Step-by-step explanation:
Squares have congruent sides.
One side is 12 inches, so all of the other sides are 12 inches.
To find the area of a square, multiply width by height. The width is 12, and the height is also 12
12 * 12 = 144
144 in ^2
Calories consumed by members of a track team the day before a race are normally distributed, with a mean of 1,700 calories and a standard deviation of 100 calories. If a normal curve is sketched using these data, what is the range for 3 standard deviations to the right and to the left of the mean?
1,400–2,000
0–3,500
1,600–1,800
1,500–1,900
Answer:
Option A is right.
Given that:
Mean = 1700
Standard deviation = 100
So, the range for 3 standard deviations to the right and to the left of the mean is:

Step-by-step explanation:
10x10=100x10=1000
Answer:
314
Step-by-step explanation:
The answer would be 314 because we know that the formula for Area is time radius squared so we plug in the information stays the same as for r it is replaced with 10 inches. We start off by multiplying by the radius or 10 but before that we square it. Squaring it is taking the number and multiplying it by itself so 10x10 giving us 100. After that we can do 3.14 x 100 to get our answer of 314.

1) The average daily rainfall in Seattle for then month June has mean absolute deviation of 1.3 inches. What conclusion can you make about the average daily rainfall in Seattle for the month of June?
Answer and show your work (10 points)
Answer:
an average of 1.3 inches
Step-by-step explanation:
Using the mean absolute deviation, it can be concluded that the daily rainfall volume differs from the mean by an average of 1.3 inches.
What is the mean absolute deviation of a data-set?
The mean of a data-set is given by the sum of all observations divided by the number of observations.
The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.
The mean absolute deviation represents the average by which the values differ from the mean.
In this problem, the mean absolute deviation is of 1.3 inches, hence, it can be concluded that the daily rainfall volume differs from the mean by an average of 1.3 inches.
