9- 4(2p+3) - 8p+7<br> how do i solve this ?

Sholpan [36]

Answer:

$= -16p+4$

Step-by-step explanation:

First we simplify:

$9-4(2p+3)-8p+7$

Then we distribute:

$=9+(-4)(2p)+(-4)(3)+(-8p)+7\\=9+(-8p)+(-12)+(-8p)+7$

Lastly, combine like terms:

$=9+-8p+-12+-8p+7\\=(-8p+-8p)+(9+-12+7)\\=-16p+4$

Hope this helps!

Have a good evening! :)

The measure of the perimeter of a triangle is 24x - 2. It is known that two of the sides of the triangle have measures of 10x +

stealth61 [152]

Answer: 6x-3

Step-by-step explanation: Say that the third side is y. The equation for the perimiter is side 1+ side 2+ side 3= perimeter which if you intput what we have turns out like (10x+2) +(8x-1)+y=24x-2. If you add 10x+2 and 8x-1 you get 18x+1. We can update the previous equation making it (18x+1)+y=24x-2. Since your trying to find y, you isloate it by subtracting (18x+1) from both sides. This leaves us with y=6x-3 as the length of thr missing side.

g Bonus: Assume that among the general pediatric population, 7 children out of every 1000 have DIPG (Diffuse Intrinsic Pontine G

patriot [66]

Answer:

0.9586

Step-by-step explanation:

From the information given:

7 children out of every 1000 children suffer from DIPG

A screening test designed contains 98% sensitivity & 84% specificity.

Now, from above:

The probability that the children have DIPG is:

$\mathbf{P(positive) = P(positive \ | \ DIPG) \times P(DIPG) + P(positive \ | \ not \DIPG)\times P(not \ DIPG)}$ $= 0.98\imes( \dfrac{7}{1000}) + (1-0.84) \times (1 - \dfrac{7}{1000})$
