Start by turning everything positive! 8n + 8 = 72.
Then, having the 8 as a positive number, subtract it from the left side. 8n = 64
In our final step, we divide 64 by 8 to find what n is, n= 8
To check your work you can plug it back into the original equation, be sure that both sides equal each other!

Answer:

n=8

Step-by-step explanation:

Add 8 to both sides of the equals sign, then bring down -8n, add -72+8, You'll get -64, lastly you divide -64 and -8, and you'll get your answer

Information on a packet of seeds claims that the germination rate is 92%. The packet contains 160 seeds.
xenn [34]

Answer: a. N(0.92, 0.0215)

Step-by-step explanation:

For population proportion (p) and sample size n, the mean and standard deviation is given by :-

The sampling distribution model for p is given by :_

N(\mu_p,\ \sigma_p)

, where

\mu_p=p \\ \sigma_p=\sqrt{\dfrac{p(1-p)}{n}

We assume that the seeds are randomly selected.

Given : Information on a packet of seeds claims that the germination rate is 92%.

i.e. p= 0.92

The packet contains 160 seeds.

i.e. n= 160

Then ,  \mu_p=0.92\\ \sigma_p=\sqrt{\dfrac{0.92(1-0.92)}{160}}\approx0.0215

Hence, the sampling distribution model for p is:

N(\mu_p,\sigma_p) = N(0.92, 0.0215)

The graph shows a line and two similar triangles.
Tanzania [10]

Answer:B mark me brainliest

Step-by-step explanation:Recall that slope is rise over run

slope = rise/run

The rise being the change in y, while the run is the change in x.

So we could informally think of it as slope = y/x

-----------

Since we're told that it "has a rise of 2 and run of 3", this means slope = 2/3.

The slope is both y/x and also 2/3.

Equating the two expressions leads us to y/x = 2/3. This is why choice B is the final answer.

What is a equation in slope intercept form for a line that passes through (5,4) and has a slope of -5
liubo4ka [24]

Answer:

Step-by-step explanation:

The easiest way to complete this is too use this data and put it into point-slope form. This is written as,  y-y1=m(x-x1)

In this equation y1 is the y- coordinate of your point and x1 is the x-coordinate. M in this case would also be known as the slope.  

Now we can submit our data-----

y-4=-5(x-5)   -------- simplify

y-4=-5x+25  --------

y=-5x+28
