Answer:
a linear equation
Step-by-step explanation:
6n+5=3n+20
<u>collect like terms</u><u>:</u>
6n-3n=20-5
3n=15
<em><u>divide both sides with the coefficient of n</u></em>
3n÷3=15÷3
n=5
Answer: a) 27.5, b) 5.33.
Step-by-step explanation:
Since we have given that
and n = 180
We need to calculate the sample mean and sample standard deviation.
So, the mean of the distribution of sample means is
The standard deviation of the distribution of sample means is
Hence, a) 27.5, b) 5.33.

Answer:
y=-1/2x-5
Step-by-step explanation:
Well we know that the slope is -1/2 so we can write the equation like this:
y=-1/2x+b (This is because of y=mx+b) (m is slope) (b is y-intercept)
Now we can replace the y and x with -4 and -3 because of (x,y). (-4,-3) x is -4 and y is -3
-3=-1/2(-4)+b
-3=2+b
Subtract 2 on both side:
-2-3=2-2+b
-5=b
Answer:
y=-1/2x-5
