What is the answer to 12x^7 over 3x

Mathematics
1 answer:
Darina [25.2K]3 years ago
8 0
Simple, what you're basically doing is simplifying,

\frac{ 12x^{7} }{3x}

well, you have 3x and you have 12x^{7}

12/3=4

and you can "cancel" out an x, making your answer,

4x^{6}.

Vikentia [17]

Answer:

Random variable: for this case represent the number of complaints in 2007

Population parameter: represent the real proportion of complaints in 2007 p

Hypothesis to verify

We want to check if the true proportion of complaints in 2007 is equal to 0.23, the system of hypothesis are.:  

Null hypothesis:p=0.23  

Alternative hypothesis:p \neq 0.23  

Step-by-step explanation:

Information provided

n=1432 represent the random sample taken

X=321 represent the number of complaints

\hat p=\frac{321}{1432}=0.224 estimated proportion of complaints in 2007

p_o=0.23 is the value to verify

z would represent the statistic

Random variable: for this case represent the number of complaints in 2007

Population parameter: represent the real proportion of complaints in 2007 p

Hypothesis to verify

We want to check if the true proportion of complaints in 2007 is equal to 0.23, the system of hypothesis are.:  

Null hypothesis:p=0.23  

Alternative hypothesis:p \neq 0.23

A cube with 2 inch sides is placed on a cube with 3 inch sides. Then a cube with 1 inch sides is placed on the 2 inch cube. What
Taya2010 [7]

Answer:

let's try the "Divide and Conquer" method, that is we break down the problem into pieces and solve each piece until we arrive at the answer.

the formula for the surface area of the cube is:

SA = 6s^2; s is the length of one side of the cube

for the 3-inch cube

SA = 6(3^2)

SA = 6(9)

SA = 54 in^2

note however, that the actual surface area is less the area occupied by the 2-inch cube place on the 3-inch cube, which is

A = s^2; since this is a square

A = 2^2

A = 4 in^2

the actual SA (aSA) therefore of the 3-inch cube is

aSA = 54 - 4 = 50 in^2

for the 2-inch cube

SA = 6s^2

SA = 6(2^2)

SA = 6(4)

SA = 24 in^2

to solve for the actual SA of the 2-inch cube, we subtract the area which is in contact with the 3-inch cube and the 1-inch cube

aSA = 24 - 2^2 - 1^2

aSA = 24 - 4 - 1

aSA = 19 in^2

for the 1-inch cube

SA = 6s^2

SA = 6(1^2)

SA = 6 in^2

the actual surface area is less the area in contact with the 2-inch cube

aSA = 6 - 1^2

aSA = 5 in^2

the surface area of the three cube tower will just be the sum of the aSA of the three cubes

SA = 50 + 19 + 5

SA = 74 in^2   ans

your school is sponsoring a pancake dinner to raise money for a field trip. You estimate that 200 adults and 250 children will a
kumpel [21]
Equation is: 200x + 250y = 3800
Put x = 0
then 250y = 3800
y = 3800 / 250
y = 15.2

Now, Put y = 0
200x = 3800
x = 3800/200
x = 19

So, the coordinates are: (19, 0) & (0, 15.2)
We will mark those coordinates & draw the line from origin. Graph is done

Hope this helps!
