Find x if 5, 9, 11, 12, 13, 14, 17 and x have a mean of 12.

Answer:

- 12 and - 187

Step-by-step explanation:

To evaluate f(- 7) substitute x = - 7 into f(x)

f(- 7) = 2(- 7) + 2 = - 14 + 2 = - 12

Similarly for g(- 4)

g(- 4) = 3(- 4)³ + 5 = 3(- 64) + 5 = - 192 + 5 = - 187

Given :

⊕   f(x) = 2x + 1

⊕   g(x) = 5x + 4

⊕   m(x) = f(x) - g(x)

⇒   m(x) = (2x + 1) - (5x + 4)

⇒   m(x) = 2x + 1 - 5x - 4

⇒   m(x) = -3x - 3

Answer:

d = 9.9 units

Step-by-step explanation:

Picture a right triangle with one acute vertex at (1, -5) and the other at (-6, 2).  Going from one to the other, we see a change in x (run) of 7 and a change in y of 7.  Applying the Pythagorean Theorem, we find the distance between the two points as follows:

d = √(7² + 7²) = 7√2, or approximately 9.9 units.

Answer:

b on edge 2021

Step-by-step explanation:

From the calculations, the length of CY in the parallelogram is 15 feet.

A diagonal is a line that runs from one end to another in a quadrilateral. We know that in such quadrilaterals as the parallelogram, the diagonals bisect each other.

Hence;

CY =WC

And

2x - 7 = x + 4

collecting like terms;

2x - x =  4 + 7

x = 11

Thus

CY = 2x - 7

= 2*11 - 7

= 22- 7

= 15

Answer and Step-by-step explanation:

To find the answer, we need to first think of what length in the rectangle can make the longest path, then use the Pythagorean Theorem.

The diagonal in a rectangle (going from one corner to another) is the longest distance.

If we were to split that rectangle by its diagonal, we would get a triangle. By the Pythagorean Theorem, we can find the length of that diagonal (the hypotenuse of the triangle).

Answer:

70

Step-by-step explanation:

2x and (4x-70) have the same measurements.

Set your formula up as

2x = 4x-70

2x-4x=-70

-2x=-70

x=35

Now substitute 35 in place of x

2x = 2*35 = 70

4x-70 = 4*35 - 70 = 70

Answer:

Oki Doki, read below this will be long.

Step-by-step explanation:

So, lets start with mr moy.

First off, we need to figure out the total hours that mr moy worked.

Throuhgout the 7 days of the week, he worked 5 days. These were his hours:

8, 8, 8, 8, 9

Adding these together, you get a total of 41 hours.

Next we have total wage.

To find this, multiply the total hours by the hourly income. We know the hourly income is 12.5, and the total hours is 41:

12.5*41=512.5

So 512.5 is the total wage.

Lets do this for the next four people, I am just going to speed it up a bit:

Ms wong - hours - 8+8+7+9+9 =41. Hourly income - 9.5. Total income: 9.5*41:

389.5 is total income

41 is total hours

Maria - hours - 5+5+6+8+9=33. Hourly income - 7.5. Total income: 7.5*33:

247.5 total income

33 total hours

Tom - 4+4+4+4+4+8+8=36. Hourly income - 7.5. Total income: 7.5*36:

270 total income

36 total hours

Jacob - 5+5+5+7+7 =29. Hourly income - 7.5. Total income: 7.5*29:

217.5 total income

29 total hours

OK, now for the total sums:

Total hourly wages - 7.5+7.5+7.5+12.5+9.5=44.5

Total of the total hours - 41+41+33+36+29=180 hours

Total of total wages - 217.5+512.5+389.5+270+247.5=1637

Ok, thats it for the first page.

On the next pages, I was slightly confused. But Ill try my best.

A - for each employ, calculate total hours and wages. We already did this before.

B - What is the total amount that is paid out in wages in a week. We already did this before(1637)

C - which day is the busiest day of the week - Saturday. The slowest? Monday

So we know the slowest day has to be monday, since the total employment hours is 8+8+4=20. WHich is lower than the rest.

We also know the busiest day has to be saturday, since the total employment hours is 9+9+8+5=31. Which is higher than the rest.

Now to the the third page.

What is the average employe wage?

Lets add up all the wages, and divide by the amount of wages:

7.5+7.5+7.5+9.5+12.5=44.5

44.5/5

=

8.9

This is the average wage.

Answer:

382.50

Step-by-step explanation:

Area of the Shaded region = Area of the larger triangle - Area of the smaller triangle;

Let's find the area of the large triangle first;

A = 1/2(base) * (height)

A = 1/2(33) * (33)

A = 16.5 * 33

A = 544.5

Now let's find the area of the small triangle;

A = 1/2(base) * (height)

A = 1/2(18) * (18)

A = 9 * 18

A = 162

Area of the shaded region;

=> 544.5 - 162

=> 382.5 (if rounded to the nearest hundredths, 382.50)

Answer:

He traveled 520 miles

Step-by-step explanation:

8 x 65 = 520

Answer: 520 miles

Step-by-step explanation:

Data: Juan drove 8 hours

Drove at an average Speed of 65 mph

Miles driven=x

Only step: Multiply 65 by 8 which is 520

Explanation: Since Juan drove at an average speed of 65 miles per hour, that means he drove 65 mile for every hour he drove. So since he drove for 8 hours, you multiply 8 hours by 65 miles so that you get get the total amount of hours driven by him.

Don't forget to add "Miles" to the end of your answer because most math teachers tend to want that in an answer like this.

Answer:

3.44.

Step-by-step explanation:

We can see that in this square, the radii of the semicircles are 2. Using that, we can calculate that the area of each one is 6.58. Both combined is 12.56. Now, the original area of the circle was 16. 16 minus 12.56 is equal to 3.44, so the area of the shaded region is 3.44.

Answer:

3.44

Step-by-step explanation:

enter it just like that in ape x

Answer:

53.94%

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean = 48 points

σ is the population standard deviation = 3 points

For x = 47 points

z = 47 - 48/3

= -0.33333

Probability value from Z-Table:

P(x = 47) = 0.36944

For x = 52 points

z = 52 - 48/3

= 1.33333

Probability value from Z-Table:

P(x = 52) = 0.90879

Hence, the probability of test scores that between 47 and 52 points is calculated as:

P(x = 52) - P(x = 47)

= 0.90879 - 0.36944

= 0.53935

Therefore, the percentage of test scores that are between 47 and 52

points is given as:

0.53935 × 100

= 53.935%

Approximately to the nearest hundredth of a percent ≈ 53.94%

Function is a set of ordered pairs that do not have same domain or x-value. That means in a set of ordered pairs, the domain cannot have same value.

The only relation that isn't function here is the last choice because in a set of ordered pairs, there are two -5's which is repetitive. Other choices do not have same x-values in one set except for the last choice.
