Answer:
0.9153
Step-by-step explanation:
Computing the z-statistics
Now we must compute the area under the Normal Curve with mean 0 and standard deviation 1 between -1.5 and 2.1
P(-1.5 < x < 2.1) = 0.9153
To compute this value we could use a calculator or a spreadsheet.
<em>In Excel or OpenOffice Calc use
</em>
<em>NORMSDIST(2.1) - NORMSDIST(-1.5)
</em>

Answer: 90
Step-by-step explanation:
450/5 or 450 divided by 5
you can work this out by figuring out 45/5 which is 9
so 450/5 equals 90

Answer:
9x + 8
Step-by-step explanation:
2(3x + 1) + 5x + 9 - 2x - 3
⇒ 6x + 2 + 5x + 9 - 2x - 3
⇒ 9x + 8
Answer:
i cannot view the image for some reason
Step-by-step explanation:
For the answer to the question above, uUnder this assumption, BE is a median. Along with any median, the centroid of a triangle is always located 2/3 of the way from the vertex to the midpoint of the opposite side, so the centroid G is 2/3 of the way from E to B.
So we have GE = (2/3)BE.
Furthermore, by segment addition, BG + GE = BE.
Since BE = 9, GE = (2/3)(9) = 6.
<span>Then BG + 6 = 9, which gives BG = 3</span>
