In an experiment with a social interaction 3 people will sit in 3 rows, how many ways can this be done

Which statements are true given the histogram? Check all that apply.

vova2212 [387]

Answer:

(a)The histogram is symmetrical. FALSE

(b) The histogram is evenly distributed. FALSE

(c) The cluster from 4 p.m.-10 p.m. means that most of the texts were sent in the afternoon and evening. TRUE

(d) More texts were sent from 6 p.m.-8 p.m. than from 8 p.m.-10 p.m. FALSE.

(e)The peak from 4 p.m.-6 p.m. means that the highest number of texts was sent during this interval. TRUE

Step-by-step explanation:

(a)The histogram is symmetrical.

FALSE, as the histogram has no line of symmetry.

(b) The histogram is evenly distributed.

FALSE, the histogram is not evenly distributed as there is no data in the

10: AM to 3:00 PM slot.

(c) The cluster from 4 p.m.-10 p.m. means that most of the texts were sent in the afternoon and evening.

TRUE, the data shows that the most texts were sent in afternoon and evening as it has the highest peaks in the given slot.

(d) More texts were sent from 6 p.m.-8 p.m. than from 8 p.m.-10 p.m.

The number of texts sent from 6 p.m.-8 p.m = 19

The number of texts sent from 8 p.m.-10 p.m = 29

But, 19 < 29

Hence, the given statement is FALSE.

(e)The peak from 4 p.m.-6 p.m. means that the highest number of texts was sent during this interval. TRUE, the highest peak indicates the highest number of texts sent in the given interval.

Which function, when graphed, would contain all the points in the table below? x 0,-1,-4 y 0,1,2

galina1969 [7]

Let's take a look at the <em>relationship</em> between x and y in this function. When we look at the first non-zero pair, (-1, 1), we can see that, in the transition from x to y, our x value was had to have been multiplied by -1. For now, we could tentatively say that y = -x. Unfortunately, the next pair, (-4, 2), debunks this hypothesis pretty quickly, as 2 ≠ -(-4). We'll need to reexamine the relationship between x and y here.

One patter that we can be fairly confident in is that multiplication by -1; the sign is flipped from negative to positive when we go from x to y in each case, so we can hold onto that component of the function. Something else is happening before that sign flip, though, and we'll need to look into that by seeing how else the numbers are connected.

Ignoring the negative signs for a moment, let's take a look at the pairs (1,1) and (4, 2). We can transform 1 to 1 pretty easily; we simply multiply or divide it by 1. From 4 to 2, we can either divide it by 2 or multiply it by 1/2. Let's thing in terms of division for now. We know that

1/1 = 1 (obviously)
4/2 = 2

We might have something here! It looks like the number we divide by and the number we obtain are the same, so let's explore this further. Multiplying both sides by those denominators, we find:

1 = 1²
4 = 2²

Almost there! To finally find the relationship, we just square root both sides to get:

√1 = 1
√4 = 2

So that was the function we'd been looking for - a square root! Putting that together with what we said about changing the sign at the beginning, we have:

y =√(-x)

To verify this, we just need to plug in a few pairs, and we find that indeed:

1 = √-(-1) = √1 = 1
2 = √-(-4) = √4 = 2
