Answer:

Step-by-step explanation:

Remark

This question is a little ambiguous. You might not be sure how to treat the Chiefs. Include their 10 or not. Turns out you do.

So the total score was 45

But this can be solved without using that information. The key is that the total number of plays made was 13

Givens

Let the touchdowns = x

Let the point after = y

Let the field goals = z

The number of point afters = the touchdowns. x = y

The number of touchdowns is 6 times the field goals: z = x / 6

Equation.

x + y + z = 13            Substitute x for y

Solution

x + x  + z = 13          Combine the left: substitute x/6 for z

2x    + x/6 = 13        Multiply by 6 to get rid of the fraction

6*2x + x = 13 * 6      Combine the left

12x + x = 13*6          Combine the left

13x = 13 * 6              Divide by 13 on both sides.

13x/13 = 6

x = 6

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

Answer

x = 6

y = 6

z = 1

Check

It's time to see what happened.

6 touchdowns = 6 * 6 = 36

6 single points = 6 * 1 =  6

1 field goal      <u>            =   3   </u>

Total                              45

Apparently we got the right answer. You made one small error in the last equation. z should equal x/6

Very interesting problem. Sports stat guys are going to love this question. Thanks for posting.

A map has a scale of
givi [52]
For ever 4 inches, you have 25 miles. Therefore if you have only one, you multiply to find the other. Now, since you have miles, you need to find inches. Therefore, 120 divided by 4, because every 4 inches is equal to 25 miles. Your answer should be 30 inches

Consider a sequence whose first three
snow_tiger [21]

Answer:

Below, depends if 27 is term number 1 or term number 0.  Answered for both cases.  

Step-by-step explanation:

The most common sequences are arithmetic and geometric, so lets check those first.

Arithmetic first since its the easiest.

to go from 27 to 21 we subtract 6, if we subtract 6 from 21 again we get to 15, which is what we need, so it is indeed arithmetic.

Explicit formula is basically of the form of y=mx+b with an arithmetic sequence.  the m is the common difference and b is the first term minus the common difference.  so lets fill those in.  y = -6x + 33

Then it usually has n as the x and y f(n) so we'll just put those in

f(n) = -6n + 33

This si as long as the first term is labeled as term number 1 and not term number 0.  if you have 27 as term 0 instead just make 33 back to 27, so f(n) = -6n + 27

Let me know if this doesn't make sense.

In a two-player game, five cards, numbered 1 through 5, are placed in a bag. A card is drawn at random, and the players look at
IceJOKER [234]

Answer:

If it is less than 3, Player 1 earns 3 points.

If not, Player 2 earns 2 points.

Step-by-step explanation:

<u>Player 1</u> :

p(N < 3) = p(N = 1 or N = 2) = 2/5

<u>Player 2</u> :

p(N ≥ 3) = p(N = 3 or N = 4 or N = 5) = 3/5

<u>We notice that</u> :

p(N < 3) × 3 = (2/5) × 3 = 6/5

On the other hand,

p(N ≥ 3) × 2 = (3/5) × 2 = 6/5

since ,the probability player 1 win multiplied by the associated number of points (3)

is equal to

the probability player 2 win multiplied by the associated number of points (2).

Then the game is fair.

The line represented by the equation 3x + 5y = 2 has a slope of - Which shows the graph of
Lubov Fominskaja [6]

Answer:

Step-by-step explanation:

Solve the given 3x + 5y = 2 for y.  This will automatically indicate the slope of the line.

Subtracting 3x from both sides of this equation, we get:

5y = -3x = -3x + 2.

Dividing both sides by 5 yields y = (-3/5)x + 2/5.

The slope of the given line is -3/5.  The y-intercept of this line is (0, 2/5).

Next time, please share the answer choicess.  Thank you.
