Answer:
area of a composite figure is finding the area of the shapes sides
<h3><u>The y-intercept is -14.</u></h3><h3><u>The x-intercept is -1.56</u></h3>
y = - 9x - 14
We already know the y-intercept of the line is going to be -14. We can tell this because the equation is written in slope-intercept form.
To find the x-intercept, we need to set the value of y equal to 0.
0 = -9x - 14
Add 14 to both sides.
14 = -9x
Divide both sides by -9.
x = 14/-9 = -1.56
Answer:
A. 1)5.5 2)4.5 3)5.75 4)6.25 B. 1.75 C. A correct B incorrect C incorrect D correct
Step-by-step explanation:
Mean is a fancy way of saying <em><u>Average </u></em>, when calculating average you add all the numbers and divide by how many numbers there are:
<em><u>A</u></em>
<u>1.</u>
8+6+3+5=22/4=5.5
<u>2.</u>
5+7+4+2=18/4=4.5
<u>3.</u>
8+7+5+3=23/4=5.75
<u>4.</u>
6+8+4+5=25/4=6.25
<em><u>B</u></em>
largest mean is 6.25, smallest mean is 4.5:
<u>Subtract lowest mean from highest mean:</u>
6.25-4.5=1.75
<em><u>C</u></em>
<u>A)</u>
this is correct because averaging your average gives an overall average,
<u>B)</u>
if a is correct b has to be incorrect
<u>C)</u>
if D is correct C must be incorrect
<u>D)</u>
The closer they are together, that means more likely to be accurate because they are almost the same
I hope this helps u!
pls pls PLS give a brainliest and a thx ;)
