Answer:

Complete the sentences.

To find the z-score for the 56th percentile means that

the area above the z-score will be ✔ 0.44 and the

area below the z-score will be ✔ 0.56.

The z-score for the 56th percentile is ✔ 0.15

First we need to differentiate y

$\\ \sf\Rrightarrow \dfrac{dy}{dx}$

$\\ \sf\Rrightarrow \dfrac{d}{dx}(-16x^2-110x+15)$

$\\ \sf\Rrightarrow -32x-110$

Now let it be 0

$\\ \sf\Rrightarrow -32x-110=0$

$\\ \sf\Rrightarrow -32x=110$

$\\ \sf\Rrightarrow x=|110/-32$

$\\ \sf\Rrightarrow x=3.44s$

Put it in y

$\\ \sf\Rrightarrow y=15-110(3.44)-16(3.44)^2$

$\\ \sf\Rrightarrow y=204.05ft$

3(-2-4v)<-90 help I'm stuck on this one <br>

Pavel [41]

Well, if you disregard the signs for a second, you can work this like a normal equation:
-6 - 12v = 90
-12v = 96
v = 8
Now just reincorporate the less than sign:
v < 8

Find the SUm of the infinite series.

givi [52]

I'll do problem 13 to get you started.

The expression $4\left(\frac{2^n}{7^n}\right)$ is the same as $4\left(\frac{2}{7}\right)^n$

Then we can do a bit of algebra like so to change that n into n-1

$4\left(\frac{2}{7}\right)^n\\\\4\left(\frac{2}{7}\right)^n*1\\\\4\left(\frac{2}{7}\right)^n*\left(\frac{2}{7}\right)^{0}\\\\4\left(\frac{2}{7}\right)^n*\left(\frac{2}{7}\right)^{1-1}\\\\4\left(\frac{2}{7}\right)^n*\left(\frac{2}{7}\right)^{1}*\left(\frac{2}{7}\right)^{-1}\\\\4*\left(\frac{2}{7}\right)^{1}\left(\frac{2}{7}\right)^n*\left(\frac{2}{7}\right)^{-1}\\\\\frac{8}{7}\left(\frac{2}{7}\right)^{n-1}\\\\$

This is so we can get the expression in a(r)^(n-1) form

a = 8/7 is the first term of the geometric sequence
r = 2/7 is the common ratio

Note that -1 < 2/7 < 1, which satisfies the condition that -1 < r < 1. This means the infinite sum converges to some single finite value (rather than diverge to positive or negative infinity).

We'll plug those a and r values into the infinite geometric sum formula below

S = a/(1-r)

S = (8/7)/(1 - 2/7)

S = (8/7)/(5/7)

S = (8/7)*(7/5)

S = 8/5

S = 1.6

------------------------

Answer in fraction form = 8/5

Answer in decimal form = 1.6

Convert 5.45787878... to a fraction. Simplify.

kondaur [170]

5.45787878 = 545787878/100000000

divide both numerator and denominator by 2 or any other number

545787878 ÷ 2 = 272893939

100000000 ÷ 2 = 50000000

272893939/50000000 is your answer
