Simplify s-8/s^2-14s+8
Arturiano [62]
To simplify this:
\frac{s-8}{s^2-14s+8}

You can factor the denominator and then cancel out some terms. But, this is not factorable. So, I think you are missing a term or you wrote this wrong.

HELP PLEASE!!! 25 Points & Brainliest!
Citrus2011 [14]

Answer:

(1) f(x)=3x+4

Ad g(x) represent f(x) after horizontal translation 2 units to the left.

g(x)=3(x+2)+4

g(x)=3x+6+4

g(x)=3x+10 is the required translation.

(2) f(x)=\frac{-2x}{3}+2

f(\frac{1}{2})=\frac{-2}{3}\cdot(\frac{1}{2})+2

f(\frac{1}{2})=\frac{5}{3}

(3) We have been given a point (1,-9); slope 2

We will use the equation:

y-y_1=m(x-x_1)

m is the give slope.

y-(-9)=2(x-1)

y+9=2(x-1)

Therefore, Option (a) is correct.

A neuroscientist measures the reaction times (in seconds) during an experimental session in a sample of cocaine-addicted (n = 8)
Marysya12 [62]

Answer:

14.69 seconds

Step-by-step explanation:

The weighted mean is used to calculate the mean of numbers which don't have the same "weight" or statistical relevance. In this case, that relevance is based on the sample size of each group from which the mean reaction times were obtained.

For all three samples, the weighted mean is obtaining by multiplying each one of the mean reaction times by its <em>n value, </em>adding them, and dividing that result by the sum of all n values.

WM=\frac{11*8+18*12+13*6}{8+12+6} =14.69\\
