Answer:
No, She is not correct.
Step-by-step explanation:
A reflection across the Y axis changes the X value.
If you look at point B and point B prime, the coordinates dont change at all. Which makes this incorrect, I believe.
Answer:
125.66
Step-by-step explanation:
Answer: mean = 318.3
Median =330
Mode= 200
Step-by-step explanation:
Mean (average) is the total sum of values in a given a data set ÷ number of values
= 3820/12
Mean= 318.3
Median= midpoint value in a given data set. When the data set is an even number, median is calculated with the 2 middle point values as n1 + n2/2
Step 1: we rearranged the data set from least to highest value to give
200,200,220, 240,300,320,340,360,380,400,420 and 440
Median= 320 + 340/2
=660/2 = 340
Mode is the value with highest frequency in a given data set, from the given question, mode = 200

Answer:
40 degrees
Step-by-step explanation:
x and 40 (degrees) are "vertical angles" and are thus equal. So x = 40 degrees.
1) -(5.8x14) = -406/5 = -81.2
2) (-1/3)(-1) = 1/3 = 0.3333333....
3) -2 + 1/4 / 1 + 1/2
-7/4 / 3/2
-1.75 / 1.5 = -7/6 = -1.166....7
What do you mean by “and”?????
Is it divided or add??
I’m only sure about the first one but tell me what and mean
