Answer:
(4,2)
Step-by-step explanation:
Solving the system of equations means to find the dot where both the lines intersect. We know by the graph that the point where the both intersect is (4,2).

The function that has the same graph as x + y = 11 is f(x) = -x + 11
<h3>Graph of functions</h3>
From the question, we are to determine the function that has the same graph as the given equation
The given equation is
x + y = 11
In the above equation, y is the dependent variable.
and
Among the given equation, f(x) is the dependent variable
Thus, we can write that
x + f(x) = 11
Isolate f(x)
f(x) = -x + 11
Hence, the function that has the same graph as x + y = 11 is f(x) = -x + 11

X=5 because 2x plus 6x equals 8x and then when you divide the 40 by 8 u get 5
Answer:
2
Step-by-step explanation:
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)
