rewona [7]

Answer:

In average, houses in the particular area use 119,6 therms of gas during the month of January.

Step-by-step explanation:

The μ formula is:

μ= ΣXi/N

ΣXi= is the sum of each xi. xi is each observation in the sample.

N= Total number of observations.

For this case:

ΣXi= 125+103+118+ 109+ 122+ 82+ 99+ 138+ 151+ 149

ΣXi= 1196

N= 10

μ= 1196/10

μ= 119,6

In average, houses in the particular area use 119,6 therms of gas during the month of January.

laiz [17]

Answer:

x = 3 2/3

Step-by-step explanation:

Given

3x - 4 = 7

Add 4 to both sides of the equation

3x - 4 + 4 = 7 + 4

3x = 11

Divide both sides by 3

3x/3 = 11/3

x = 3 2/3

Select the graph and the description of the end behavior of f(x) = x3 + 2.
Dmitry [639]
F(x)=x^3+2
we see the power is odd
the ends go in opsoite directions
we know that if the leadind coefient (number in front of highest power term) is positive, then odd powered polynomials go from bottom left to top right
and for even ones, it goes both up

for negative, odd ones go from top left to bottom right
for even, both go down

we gots
f(x)=1x^3+2
positive and odd, so it goes from bottom left to top right

as x approaches negative inifnity, y approaches negaitve infinity
as x approaches infinity, y approaches infinity
