According to the line plot what is the total amount of time spent studying by all students who studied 1/4 hour or 3/4 hour​

Answers

Answer:

2  3/4 hours

Step-by-step explanation:

We see from the figure that 2 students spent 1/4 hours and 3 students spent 3/4 hours.

So the total time spent is

2* (1/4) + 3(3/4) hours

= 1/2 + 9/4

=(2+9)/4  taking l.c.m

= 11/4

= 2 3/4 hours

The total time spent by 5 students on 1/4 hours and 3/4 hours is 2 and 3/4 hours.

BRAINIEST TO WHOEVER RIGHT “ identify the box and whisker plot that represents the data.” “Cat lengths (in inches) : 16, 18, 20, 25, 17, 22, 23, 21”

Answers

The second box/whisker plot is correct.

First we have to put he data set in ascending order:

16, 17, 18, 20, 21, 22, 23, 25

The median (middle number or average of 2 middle numbers) = 20.5 The center line of the box needs to be at 20.5

The middle of the first half of the data is 17.5, (average of 17 & 18) so the left side of the box needs to be at 17.5

The middle of the second half of the data is 22.5, (average of 22 & 23), so the right side of the box needs to be at 22.5.

The “whiskers” are your bottom & top numbers...representing the full range of data. They should be at 16 & 25.

Which statement is true about the lines 3−2=27 3 y - 2 x = 27 and 4−2=36 4 y - 2 x = 36 ?

Answers

The two lines 3 y - 2 x = 27 and 4 y - 2 x = 36 are parallel to each other because their slopes (i.e., -2/3 and -2/4) are equal.

What are parallel lines?

Parallel lines are lines in a plane that do not intersect and are always the same distance apart. They have the same slope and will never meet, regardless of how far they are extended.

Therefore, the correct answer is as given above. It can be concluded that lines 3 y - 2 x = 27 and 4 y - 2 x = 36 are parallel lines to each other for their slopes (i.e., -2/3 and -2/4) are the same.
