Paralalell means that is has the same slope
y=mx+b
m=slope
y=-1x-2
slope=-1
the equation of a line that passes through the point (x1,y1) and has a slope of m is y-y1=m(x-x1)
given
(2,-2) and slope is -1
y-(-2)=-1(x-2)
y+2=-x+2
minus 2
y=-x
answer is y=-x
The polynomials which, when added to the polynomial 3x²+3x-1, is equivalent to the following expressions: 1, 2x²-3, and x+5 are respectively;
- P = 2 - 3x² -3x.
- P = -2 -x² -3x
- P = 6 -2x -3x².
<h3>Addition of polynomials</h3>
For the expression; 1; we have;
P = 2 - 3x² -3x.
For the expression; 2x²-3; we have;
P = -2 -x² -3x
For the expression; x +5; we have;
P = 6 -2x -3x².

Answer:
48 and 4
Step-by-step explanation:
If we assume that
to be the random variable that proceed the normal distribution with mean
and a standard deviation ![\dfrac{\sigma }{\sqrt{n}}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Csigma%20%7D%7B%5Csqrt%7Bn%7D%7D)
Given that:
mean =48
standard deviation = 16
sample size = 16
The population mean is same as the population mean in sampling distribution that is 48.
The standard deviation of the sampling distribution is therefore calculated as:
standard deviation = ![\dfrac{\sigma }{\sqrt{n}}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Csigma%20%7D%7B%5Csqrt%7Bn%7D%7D)
standard deviation = ![\dfrac{16 }{\sqrt{16}}](https://tex.z-dn.net/?f=%5Cdfrac%7B16%20%7D%7B%5Csqrt%7B16%7D%7D)
standard deviation = ![\frac{16}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B4%7D)
standard deviation = 4
Thus; the mean and the standard deviation of the sampling distribution is 48 and 4
(10^4)^2 = 10^(4*2) = 10^8
1 metric ton = 10^8 = 100,000,000 grams.
I’m pretty sure it’s the third one sorry if i’m wrong
