Answer:

12x^2-16x

Step-by-step explanation:

4x+2x^2=4x(3x-5)

4x+4x(3x-5)

( 4x*3x-5)=12x^2-20x

4x+12x^2-20x

4x-20x= -16x

=12x^2-16x

The answer is No

Explanation:

All statistical questions involve collecting numerical data (usually from a group of people) and then analyzing it to draw conclusions about the opinions of people of a certain phenomenon as the data varies depending on the response of each person. This process is not required to determine the area of the floor because this has a unique answer and can simply be found by measuring the height and width of the classroom and then multiplying both numbers. Also, this does not imply gathering a lot of data and the data does not vary.

Answer:

Part A: The unit that would be best to describes the situations is to the mile

Part B: 4 significant figures

Part C: 1,450 miles

Part D: He is not correct

Step-by-step explanation:

Part A: By unit conversion, we have;

1 mile = 1,760 yards

Given that the distance from Ottawa, Canada to Jackson Mississippi is 2,552,000 yards it would best simplified into miles

Part B: The number of significant digits in the reporters estimate are the non-zero digits before the zeros in the number figure which are 2, 5, 5, and 2 or 4 significant figures

Part C: 2,552,000 yards = 2,552,000 yards/(1,760 yards/mile) = 1,450 miles

Part D: Given that the distance from Jackson to Tucson = 7,159,680 feet, we have;

1 mile = 5,280 feet

Therefore;

7,159,680 feet = 7,159,680 feet/(5,280 feet/mile) = 1,356 miles

Therefore, the claim that the distance from Jackson to Tucson which is 1,356 miles is further than the distance from Ottawa, Canada to Jackson Mississippi which is 1,450 miles is not correct because;

The distance from Jackson to Tucson 1,356 miles [tex]\ngtr[/tex] 1,450 miles which is the distance from Jackson to Ottawa

Answer : The different is, find BC - AC and find AC + CB, find AB and find CA + BC are same.

Step-by-step explanation :

As see that, AB is a line segment in which point C is represented in between the line.

As we are given that:

AC = 3

CB = 7

So,

AC + CB = 3 + 7 = 10

Similarly,

CA + BC = 3 + 7 = 10

Similarly,

AB = AC + CB = 3 + 7 = 10

But,

BC - AC = 7 - 3 = 4

From this we conclude that, find AC + CB, find AB and find CA + BC are same things while find BC - AC is a different thing.

Hence, the different is, find BC - AC and find AC + CB, find AB and find CA + BC are same.

Answer:

P (X = 5) = a and P (X = 6) = 0.38 - a

Step-by-step explanation:

The sum of probabilities of all the events in a sample space is known is 1.

That is:

[tex]\sum\limits^{n}_{i=1}[P(X=x_{i})]=1[/tex]

It is provided that, the random variable X, can assume values 0, 1, 4, 5, and 6.

The incomplete probability distribution is:

X        P(X = x)

0          0.26

1           0.25

4           0.11

5             __

6            __

Compute the missing probabilities as follows:

[tex]\sum\limits^{n}_{i=1}[P(X=x_{i})]=1[/tex]

[tex]P(X=0)+P(X=1)+P(X=4)+P(X=5)+P(X=6)=1\\\\0.26+0.25+0.11+P(X=5)+P(X=6)=1\\\\0.62+P(X=5)+P(X=6)=1\\\\P(X=5)+P(X=6)=1-0.62\\\\P(X=5)+P(X=6)=0.38[/tex]

Assume that P (X = 5) = a.

Here the value of a lies in the interval 0 ≤ a ≤ 0.38.

Then the value of P (X = 6) will be:

P (X = 6) = 0.38 - a

Thus, the complete probability distribution is:

X            P(X = x)

0              0.26

1               0.25

4               0.11

5                  a

6            0.38 - a

Answer:

Step-by-step explanation:

The domain of the function f(x) = 6.5x will be a positive real number.

The domain means all the possible values of x and the range means all the possible values of y.

The distance that a jogger travels at a constant speed of 6.5 miles per hour can be modeled by the linear function f(x) = 6.5x, where x is the time in hours the jogger runs.

We know that time is a scalar quantity. Then the value of the time is always greater than equal to zero.

x ≥ 0

The domain of the function f(x) = 6.5x will be a positive real number.

Answer:

24, 72, and 84

Step-by-step explanation:

Let the first, second, and third angles be A, B, and C, respectively.

So, first of all, since the figure is a triangle, the three angles must total 180. Thus:

[tex]A+B+C=180[/tex]

Now, we are told that the measure of one angle (let's use A) is 3 times the measure of a second angle (B). So:

[tex]A=3B[/tex]

And the measure of the third angle (C) is 12 less than the sum of the other two (A&B). Therefore:

[tex]C=(A+B)-12[/tex]

For this equation substitute A for 3B:

[tex]C=(3B+B)-12[/tex]

Combine like terms:

[tex]C=4B-12[/tex]

So we have the following equations thus far:

[tex]A+B+C=180[/tex]

[tex]A=3B[/tex]

[tex]C=4B-12[/tex]

So, substitute A and C in for the first equation:

[tex]A+B+C=180\\(3B)+B+(4B-12)=180[/tex]

Combine like terms:

[tex]8B-12=180[/tex]

Add 12 to both sides:

[tex]8B=192[/tex]

Divide by 8:

[tex]B=24[/tex]

So, the second angle B is 24 degrees.

The first angle A is three times B. Thus, A is 3(24)=72 degrees.

And C is 12 less than the sum of them. Thus:

[tex]C=(72+24)-12\\C=96-12\\C=84[/tex]

So, our angles are:

24, 72, and 84

And we are done :)

So the equation is y= 5+2x

and x+y=44

So we use the substitution method and says that y=44-x

So 44-x=5+2x

Step-by-step explanation:

Let x= first number

Let y= Second number

----------------------------------

y-5=2x

x+y=44

--------------------------------

y=2x+5

x+y=44

In other words, the one-time cost is $25 and there will be a cost of $14 each month.

We can write this as:

[tex]f(x)=14x+25[/tex]

Where f(x) equals the total cost given the number of months x.

For 6 months, the total cost will be:

[tex]n=\frac{3f-8}{10}[/tex]

Step-by-step explanation:

So we have the equation:

[tex]\frac{3}{4}f-\frac{5}{2}n=2[/tex]

First, remove all the fractions by multiplying by the LCM of the denominator.

The LCM of 4 and 2 is 4. Thus:

[tex]4(\frac{3}{4}f-\frac{5}{2}n)=4(2)[/tex]

Distribute:

[tex]4(\frac{3}{4}f})-4(\frac{5}{2}n})=4(2)[/tex]

Simplify:

[tex]3f-10n=8[/tex]

Subtract 3f from both sides:

[tex](3f-10n)-3f=(8)-3f\\-10n=8-3f[/tex]

Divide both sides by -10:

[tex]n=\frac{8-3f}{-10}[/tex]

Divide by -1:

[tex]n=\frac{3f-8}{10}[/tex]

And this is our answer :)

n = (3f - 8)/10

3f/4 - ²⁾5n/2 = ⁴⁾2

3f - 10n = 8

3f - 8 = 10n

n = (3f - 8)/10

Answer:

The function is [tex]d=10t[/tex]

domain is 0 to 0.2 hour.

range is 0 to 2 miles.

Step-by-step explanation:

Given that,

Average velocity = 10 miles/hour

Time = 12 min = 0.2 hour

We need to write a function that models the student's distance from home

Using formula of distance

[tex]d=v\times t[/tex]

Where, v = velocity

t = time

d = distance

Put the value into the formula

[tex]d=10t[/tex]

This is a function.

We know that,

Domain :

Domain shows the time.

So, domain = 0 to 0.2 hour

Range :

Range shows the distance.

The range at t =0,

Put the value of t in the function

[tex]d = 10\times0=0[/tex]

The range at t =0.2 hour

[tex]d = 10\times0=0[/tex]

[tex]d=2\ miles[/tex]

So. range = 0 to 2 miles

Hence, The function is [tex]d=10t[/tex]

domain is 0 to 0.2 hour

range is 0 to 2 miles
