Mean of total 5 digits is 18.6

Given:

Mean of first 3 digit = 19

Mean of next 2 digit = 18

Find:

Mean of total 5 digits

Computation:

Sum of first 3 digit = Mean of first 3 digit × Number of digits

Sum of first 3 digit = 19 × 3

Sum of first 3 digit = 57

Sum of next 2 digit = Mean of first 3 digit × Number of digits

Sum of next 2 digit = 18 × 2

Sum of next 2 digit = 36

Total of 5 digit = Sum of first 3 digit + Sum of next 2 digit

Total of 5 digit = 57 + 36

Total of 5 digit = 93

Mean of total 5 digits = Total of 5 digit / 5

Mean of total 5 digits = 93 / 5

Mean of total 5 digits = 18.6

The answer is "mean of all 5 digits is 18.6" and the further calculation can be defined as follows:

Mean of 3 digits:

[tex]\to \bold{\frac{a+b+c}{3}}=19[/tex]

Mean of 2 digits:

[tex]\to \bold{\frac{d+e}{2}}=18[/tex]

Find:

Mean of all 5 digits =?

Calculating the sum of 3 digits:

[tex]\to \bold{\frac{a+b+c}{3}}=19\\\\\to \bold{a+b+c}=19 \times 3\\\\\to \bold{a+b+c}=57\\\\[/tex]

Calculating the sum of 2 digits:

[tex]\to \bold{\frac{d+e}{2}}=18\\\\\to \bold{d+e}=18\times 2\\\\\to \bold{d+e}=36\\\\[/tex]

Calculating the Mean of all 5 digits:

[tex]\to \bold{\frac{a+b+c+d+e}{5}}= \bold{\frac{57+36}{5}}[/tex]

                       [tex]= \bold{\frac{93}{5}}\\\\=\bold{18.6}[/tex]

So, the mean of all 5 digits is "18.6".

Answer:

Q1 = 5

Step-by-step explanation:

Q1 is the first quartile

Divide the data in half, that will get you Q2 or the second quartile

There are 13 data points so the middle is the 7th data point

2, 3, 5, 5, 6, 8,    8,       9, 10, 11, 11, 11, 12

Take the lower half of the data and divide it in half

There are 6 data points so the middle is between the 3rd and the 4th data point so we average them

2, 3, 5,    5, 6, 8,

(5+5)/2 = 10/2 = 5

The 1st quartile or Q1 = 5

Using probability concepts, it is found that the matchings are:

Answer:

270 rupees

Step-by-step explanation:

Find the cost of 1 Kg by dividing cost by 12

180 ÷ 12 = 15 rupees

Then multiply this by 18

cost of 18 Kg = 18 × 15 = 270 rupees

Hello :D

12kg = 180 rupees

180/12 = 15 rupees

1kg = 15 rupees

6 x 15 = 90 rupees.

18kg = 180 + 90 = 270

18kg = 270 rupees.

Answer:

The total length of the paths is approximately [tex]50[/tex] meters.

Step-by-step explanation:

Step 1 of 3

The park is a quadrilateral with vertices J, K, L, & M, containing 4 entrances at the midpoint of each pair of vertices. (i.e. between J & K, K & L, L & M, M & J). So, you can start off this problem by finding the midpoint, or park entrance, coordinates for all four entrances.

Remember, the midpoint formula is as follows:      

(this results in the coordinate of the midpoint in the form x,y)

For example: The midpoint between vertices [tex]J(-3,1) \& K(1,3)[/tex]can be found using the midpoint formula:

Step 2 of 3

The park entrances existing at the midpoint of the vertices, then, are as follows:

Entrance [tex]J-K : (-1,2)[/tex]

Entrance [tex]K-L : (3,1)[/tex]

Entrance [tex]L-M : (2,-1)[/tex]

Entrance [tex]M-J : (-2,0)[/tex]

Now, assuming you have this nicely graphed, it should be straightforward how to measure the distance of the paths connecting the entrances opposite one another. All you have to do now is use the distance formula to calculate how many units each opposite entrance is from one another.

Step 3 of 3

Distance Formula: [tex]$\sqrt{\left(X_{2}-X_{1}\right)^{2}+\left(Y_{2}-Y_{1}\right)^{2}}$[/tex]

Your answer will be the path length between Entrances at [tex](-1,2) \& (2,-1)[/tex] as well as the path length between entrances at [tex](3,1) \& (-2,0).[/tex] You will have two answers. Just remember whatever your answer comes out to, it is in graphical units (1 tick mark equals 1 unit), however, in this problem, one unit actually represents [tex]10[/tex] meters. So, pretending you end up with [tex]5[/tex] units as your answer, it will really equal [tex]50[/tex] meters.

Answer:

8 hours

Step-by-step explanation:

when sheʻs helping him theyʻre working together so 8/2= 4

when sheʻs working alone itʻll be 4 x 2 =8

Explanation:

Let's say we measure the job in terms of square feet. So let's say the house is 320 square feet.

If Dan can dust the house in 8 hours on his own, then his unit rate is 320/8 = 40 sq ft per hour.

After 4 hours, he can dust 4*40 = 160 sq ft of the house. This leaves 320-160 = 160 sq ft for Mary to handle.

Her unit rate is (160 sq ft)/(4 hrs) = 40 sq ft per hour. It's a coincidence that the two people happen to have the same unit rate (that won't always be the case). Because her unit rate is identical to Dan's rate, this means she takes the same amount of time to get the job done if she works alone.

Side note: this all assumes that the two workers do not hinder one another, or get in each others way, in any fashion. So in a sense, they split up the house down the middle.

Add the two amounts together:

0.56 + 0.27 = 0.83 pounds total

Luis buys 0.56 pound of power pasta. Mariana buys 0.27 pound of power pasta. How much do they buy in all?

First, understand the problem.

Luis buys 0.56 pounds of power pasta.

Mariana buys 0.27 pound of power pasta.

Then, add the bus of Luis and Mariana.
