If mean of first 3 digits is 19 and next 2 digits is 18, what would be the mean of all 5 digits?
Answers
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:
The mean would be the total number divided by the number of numbers. To obtain the mean, we add all the numbers and divide by number.It is also known as the "average" value, which was established by summing all data points then divided by the information gain amount.Its most popular statistics used to measure the center of a collection of data and analysis are the statistics sometimes referred to it as average by statistics.In this question, let the value are a,b,c..., and e So,Mean of 3 digits:

Dan can dust the house in 8 hours. If Mary helps, it takes them 4 hours. Without help, how long would it take Mary to complete this job
Answers
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.

Which graph represents the system of inequalities
Answers
For the top left graph I will pick (2, -2)
-2 - (2 x -2) = 2 < -3 false so we don’t need to test the others
For top right graph I will pick (-3, 0)
0 - (2 x -3) = 6 < -3 false
For the bottom left graph I pick (2, 0)
0 - (2 x 2) = -4 < -3 true
0 - 4 = -2 x 2 true
0 > -1/4 x 2 true

if the price of 12 kg rice is rupees 180 then the price of 18 kg rice is
Answers
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.

A city planner designs a park that is a quadrilateral with vertices at J(−3, 1), K(3, 3), L(5, −1), and M(−1, −3). There is an entrance to the park at the midpoint of each side of the park. A straight path connects each entrance to the entrance on the opposite side. Assuming each unit of the coordinate plane represents 10 meters, what is the total length of the paths to the nearest meter? Round your answer to the nearest whole number. The total length of the paths is approximately ? meters.
Answers
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.
