Please answer correctly, will mark brainliest

Answer correctly?  That makes it harder.

I'm going to sort the data and drop the negative signs; we just have to remember to put them back as needed later.

9 12 14 18 39 43 49 49

We have n=8 data points.

The mode is the most frequent data value; here it's 49, which occurs twice, really -49.

The range is max - min, so 49 - 9 = 40.  That one doesn't get a minus sign; range is always positive.

The sum of the points is 9+12+14+18+39+43+49+49=233

The mean is sum/n = 233/8 = 29.125, really -29.125

That's enough to answer the question, but for completeness let's get the median, which is the middle value.  When we have an even number of values, 8 here, it's the average of the two middle values, the fourth and fifth, here.

median is (18 + 39)/2 = 28.5, really -28.5

mean -29.1, median -28.5, mode -49, range 40; last choice

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
