Answer:
Option A: -12x-8=10 is the correct answer.
Step-by-step explanation:
Given equation is:
-4 (3x+2) = 10
We will distribute the equation by multiplying the terms inside the brackets with -4.
Therefore,
-4*3x + 2*-4 = 10
-12x +(-8) = 10
-12x - 8 = 10
The equation -4 (3x+2) = 10 will become -12x-8=10 after distributing.
Hence,
Option A: -12x-8=10 is the correct answer.
using the formula:
y = mx +b
Using the given slope and coordinate points we get:
-1 = -3(2) + b
-1 = -6 + b
add 6 to each side
5 = b
y = -3x + 5
which is the same as:
3x + y = 5 ...answer choice a
Answer:
![E(x)=1](https://tex.z-dn.net/?f=E%28x%29%3D1)
Step-by-step explanation:
From the question we are told that:
Sample mean 1 ![\=x_1=$9](https://tex.z-dn.net/?f=%5C%3Dx_1%3D%249)
Sample mean 1 ![\=x_2=$8](https://tex.z-dn.net/?f=%5C%3Dx_2%3D%248)
Sample standard deviation 1 ![\sigma_1 = $2](https://tex.z-dn.net/?f=%5Csigma_1%20%3D%20%242)
Sample standard deviation 1 ![\sigma_2 = $1](https://tex.z-dn.net/?f=%5Csigma_2%20%3D%20%241)
Generally the equation for Point estimate is mathematically given by
![E(x)=\=x_1-\=x_2](https://tex.z-dn.net/?f=E%28x%29%3D%5C%3Dx_1-%5C%3Dx_2)
![E(x)=9-8](https://tex.z-dn.net/?f=E%28x%29%3D9-8)
![E(x)=1](https://tex.z-dn.net/?f=E%28x%29%3D1)
