Answer:
A' ( 2, 4) and B' ( -4, 0)
Step-by-step explanation:
A ( -2, 4) and B( 4,0) reflected over the y-axis
A' ( 2, 4) and B' ( -4, 0)
the y-coordinate do not change and the x is opposite sign
(x,y) reflected over y-axis (-x, y)
Answer:
Tom was speeding.
Step-by-step explanation:
The driving speed of Tom = 20.3 meters per second.
Speed allowed in the zone = 45 miles per hour zone.
Since the unit of speed allowed is given in miles per hour but the speed of tom is given in meters per second. So, first, we have to convert the meter per second into mile per hour then we can compare and find that Tom is speeding or not.
1 mile = 1609.34 meters
1 hour = 3600 second
Now convert 20.3 into mile per hour.
20.3 meters per second. = (20.3 / 1609.34)*3600 = 45.40981 mile per hour.
Since Tom’s speed is more than the allowed speed so he is speeding.
Answer:
C
Step-by-step explanation:
min and max are correctly the same for all 4 answers.
we have 10 data points, so, the median is the mean value between the 2 middle numbers, 19 and 22 : 20.5.
ah, it can be only C or D.
Q1 is the median of the lower half of data points (13 out of 11, 12, 13, 17, 19). and Q3 is the median of the upper half of data points (29 out of 22, 24, 29, 33, 38).
so, C is correct.
Solution :
Given :
National mean score of the reading test that is conducted the NAEP = 288
Standard deviation of the score = 38
Therefore, P(X > x) = 0.25
P (Z > 
= 0.674)
x = 326.67
Therefore, the highest score that is needed for the students to be in the top of 25 percent among the students those who take the exam.
Answer:
she read 165 words per minute
Step-by-step explanation:
if you tell us that Gillian read 3135 words in 19 minutes we can represent it as follows
19 m = 3135w
so now we have to find out how much I read in 1 minute, for this we have to divide both parts of equality by 19
19m = 3135w
19m/19 = 3135w/19
1m = 165w
she read 165 words per minute
