Answer:

1/56

Step-by-step explanation

First, find the common denominator

8 x 7 = 56

7 x 8 = 56

Your new equation is now:

7/56 - 6/56 = 1/56

Answer:

1.5

Step-by-step explanation:

Answer:

1.5

Explanation:

-4  -3  0  1.5  5.5  7

this is because the median is 1.5 and if you cross out every number from each number u'll find urself with 1.5.

ex:

-4 -3 -2 -1 0 1 2 3 4 5 6 7

-3 -2 -1 0 1 2 3 4 5 6

-2 -1 0 1 2 3 4 5

-1 0 1 2 3 4

0 1 2 3

1 2

and in between 1 and 2 is 1.5 so 1.5 is ur answer

Answer: C) 40th percentile

=========================================================

Explanation:

The original list is {827,691,616,740,651,772,868,557,891,937} which has 10 items inside it.

The list sorts to {557,616,651,691,740,772,827,868,891,937}

We see that there are 3 items below 691. So one way to calculate the percentile is to do 3/10 = 30% like you did for your answer.

However, the term "percentile" is ambiguous as there is another way to calculate percentile. The other method involves the term in question. So we have 4 terms in the sublist {557,616,651,691} which is how your friend got 4/10 = 40%

It's unfortunate why this term is not well defined. Ideally your teacher would state instructions on how to deal with this dilemma, or post a formula to use.

The good news is at least "30th percentile" isn't listed as an answer choice, so we can rule out the first method above.

Answer:

1392 x 10 m

Step-by-step explanation:

Answer:

1.392 x 10⁹ m

Step-by-step explanation:

when you put numbers in scientific notation, there is one (1) non-zero number before the decimal

1.392

now count how many place you would have to move the decimal to the right in order to make 1,392,000,000

9 place

this means your second half looks like x 10⁹

now put it all together

1.392 x 10⁹ m

Answer:

A current of 5 amperes will produce the maximum power.

Step-by-step explanation:

Let be [tex]p(x) = -12\cdot x^{2}+120\cdot x[/tex], where [tex]p(x)[/tex] is measured in watts and [tex]x[/tex] in amperes. At first we must obtain the first and second derivatives of the function to determine the current associated with maximum power. That is:

First derivative

[tex]p'(x) = -24\cdot x + 120[/tex]

Second derivative

[tex]p''(x) = -24\cdot x[/tex]

Now, we equalize the first derivative to zero and solve it afterwards: (First Derivative Test)

[tex]-24\cdot x + 120 = 0[/tex]

[tex]x = 5\,A[/tex]

The only critical point is [tex]x = 5\,A[/tex].

As next step we need to assure that critical point leads to an absolute maximum by evaluating the critical point found above in the second derivative: (Second Derivative Test)

[tex]p(5)'' = -24\cdot (5)[/tex]

[tex]p''(5) = -120[/tex]

Which indicates that critical point leads to an absolute maximum.

A current of 5 amperes will produce the maximum power.

Step-by-step explanation:

[tex] \sf{27 {m}^{3} - 64}[/tex]

[tex] \dashrightarrow{ \sf{( {3m)}^{3} - {(4)}^{3} }}[/tex]

Use the formula of a³ - b³ = ( a - b) ( a² + ab + b² )

[tex] \longrightarrow{ \sf{(3m - 4)(3 {m}^{2} + 3m \times 4 + {4}^{2} }})[/tex]

[tex] \longrightarrow{ \sf{(3m - 4)( {9m}^{2} + 12m + 16}})[/tex]

Answer:

C

Step-by-step explanation:

The initial value obtained using the slope-intercept relation is 3 gallons.

We need to obtain the rate of change which gives the amount of gas entering into his car per second :

Rate of change = - 11 - 3) / (48 - 0)

Rate of change = 8/48 = 1/6 gallons

Using the slope intercept relation :

Choosing any pair of (x, y) point on the table :

(0, 3)

3 = 1/6x + c

3 = 1/6(0) + c

3 = 0 + c

c = 3

Therefore, the initial value is 3 gallons.

Answer:

We know that Jennifer ran 10k last weekend.

Now, we have the function:

t = f(k) = 7*k

(notice that this is a linear function)

First, let's define what is the range.

The range is the possible values that the outcome, t, can take.

To see the range, we first must see the domain (the possible values of of the input)

In this case, we know that the minimum value of k is 0 (the time to run 0 kilometers)

t(0) = 7*0 = 0

Here we found the minimum of the range.

Now, the maximum value in the domain is 10 (because she ran 10km, we can not have a value of k larger than 10)

The time is:

t(10) = 7*10 = 70

This will be the maximum of the range.

Then the range can be written as:

R = [0, 70]

Answer: The bottom left option.

Step-by-step explanation:

←XY→ is the line that connects the points X and Y.

The fact that the planes C and D intersect at this linea, means that all the points where the planes are intersecting are points in the given line.

Then the correct option is the bottom left one, because the planes D and C are intersecting in a line, and the line passes through the points X and Y, so that line is called ←XY→.

Answer:

3:11

Step-by-step explanation:

3x=11y

Rearrange to the format of the ratio.

11y = 3x

Let's find y/x. y/x is y:x.

11y = 3x

Divide both sides by 11.

11y/11 = 3x/11

y = 3x/11

NOW LET'S DIVIDE BOTH SIDES BY x TO GET x AS THE DENOMINATOR OF y.

y = 3x/11

y/x = (3x/11)/x

y/x = (3x/11) * 1/x

y/x = 3/11

Therefore, y:x = 3:11

Answer:

5/12<3/6

Step-by-step explanation:

3/6 is 1/2 and 5/12 is smaller than 1/2

Answer:

5/12 < 3/6

Step-by-step explanation:

3/6 is equivalent to 6/12 because 3 times 2 is 6 and 6 times two is 12. 6 (the new numerator of 3/6) is greater than the numerator of 5/12- 5. 5<6. They have the same denominator so 5/12< 6/12 which is the same as 5/12 < 3/6. Hope that helped!
