Answer:
y =
- 8
Step-by-step explanation:
given slope m = 
point (5, -2) for (x1, y1)
equation for point slope form
y - y1 = m(x- x1)
y - (-2) =
(x -5)
y + 2 =
x - 6, simplify
y =
- 8,
further you can multiply by 5 to get rid of fraction
5y = 6x - 40

Answer:
10=10
Step-by-step explanation:
y-3x+15=10
y=3x-15+10
y=3x-5
subtitute y=3x-5 in the above equation:
3x-5-3x+15=10 (3x will be eliminated with -3x)
-5+15=10
10=10
(i hope this is the way you want the answer but at least I think it is correct)
Answer:
12 for each rope
Step-by-step explanation:
half of 24 is 12
A binomial distribution is an experiment where there are
two outcomes; Success and failure. For instance, you are given n = 128 and p = 0.27.
The formula for the variance of a binomial distribution is n*p(1 – p) or
n*p*q*. They are equivalent because q = 1- p. We will use the first equation.
Variance = n*p*(1 – p)
Variance = 128*0.27*(1 – 0.27)
Variance = 25.23
To get the standard deviation, find the square root of
the variance.
Standard deviation = sqrt (Variance)
Standard deviation = sqrt (25.23)
