Answer: 22 minutes

Step-by-step explanation:

Since, if x_1 people take n_1 days for doing w_1 work while  x_2 people take n_2 days for doing w_2 work,

Then,

\frac{x_1\times n_1}{w_1}=\frac{x_2\times n_2}{w_2}

Here, x_1 = 10, n_1=22\text{ minutes}, w_1=10 x_2=14  and w_2=14,

By substituting these values in the above equation,

We get,

\frac{10\times 22}{10}=\frac{14n_2}{14}

\implies \frac{2200}{10}=n_2

\implies 22=n_2

Hence, the time taken by 14 workers making 14 walls is 22 minutes.

220pm=10w  (people*minutes)

w=22pm

14w=308pm

308pm/14p=22m

So it would take 22 minutes for 14 people to paint 14 walls.

What is the Mean,Mode and range of the set below?:
Zepler [3.9K]

Answer:

Set of numbers: 5, 6, 8, 10, 11, 15, 17, 25, 29, 29, 41, 50, 51, 52, 52, 54, 56, 57, 57

Mean: 32.89

Median: 29

Mode: 29, 52, 57

Range: 52

Step-by-step explanation:

The numbers are already ordered for us, so to find the mean, we need to add the numbers and divide the sum by the number of numbers. This gives us about 32.89.

The median is the middle number in the set, so right in the middle of the set is  29.

The range is the biggest number minus the smallest number, which would be 57-5 = 52.

Mode is the value or values in the data set that occur most frequently, which would be 29, 52, and 57, because they all occur the same number of times.

Happy learning and sorry for the late answer!

If the measure of an angle 38 , find the measure of its complement
Darya [45]
If you’re finding the measure of its complement, the sum of both angles will always be 90*

x+38 = 90
-38 | -38

x = 52

the measure of its complement is 52*

INT1 4.1.1 Line of Best Fit (classwork)
Lorico [155]

Answer:

a. 2401.06

b. 37.54%

c. 56.3%

Step-by-step explanation:

hopefully this is right

*note: I think you forgot to convert 4-2 back into yards.

a. Robbie's field of view to the North end includes parts not on the football field. so to find the area of the football field he can see, we need to find:

total area of what Robbie sees - area of non football field Robbie sees

what you shaded represents the total of what Robbie sees. it's a triangle. area of a triangle is 1/2(b)(h) where h is distance away and b is width of view.

total area = 1/2(170)(30.92) = 2628.56 yd

area of non football field (pipe to South end)

= 1/2(50)(9.1) = 227.5

so 2628.56 - 227.5 = 2401.06

b. area found in part a / total area of football field

2401.06 / (120*53.3) = .3754

.3754 * 100 = 37.54%

c. the chance of Robbie seeing the touchdown depends on how much of the (North) endzone he can see.

area of north endzone is

10 * 53.3 = 533.

area Robbie sees in endzone is

2628.56 - 2328.48 = 300.08

(found by total area Robbie sees - area of non endzone Robbie sees)

300.08 / 533 = 0.563

= 56.3%
