When we multiply a vector by an scalar, it's the same as multiply all the coordinates by the same scalar, so let's suppose I have a vector "u" and multiply by the scalar "λ"
[tex]\Large\displaystyle\text{$\begin{gathered}u = \left(x, y\right)\\ \\\lambda u = \left(\lambda x, \lambda y\right)\end{gathered}$}[/tex]
Just multiply everything by "λ"!
So we have
[tex]\Large\displaystyle\text{$\begin{gathered}\frac{35}{2}\left(\frac{6}{5}v\right)\end{gathered}$}[/tex]
We can simplify the fraction
[tex]\Large\displaystyle\text{$\begin{gathered}\frac{35}{2}\cdot \frac{6}{5}v\\ \\7\cdot 3 v\\ \\21 v\end{gathered}$}[/tex]
So we want to multiply v by the scalar 21, it means that we'll multiply all coordinates by 21, we know that v = (5, 6).
[tex]\Large\displaystyle\text{$\begin{gathered}21v = 21\left(5,6\right)\\ \\21v = \left(21\cdot 5,21\cdot 6\right)\\ \\21v = \left(21\cdot 5,21\cdot 6\right)\\ \\21v = \left(105,126)\\ \\\end{gathered}$}[/tex]
So
[tex]\Large\displaystyle\text{$\begin{gathered}21v = \left(105,126)\\ \\\end{gathered}$}[/tex]

What is Q1 for this data set?
{2, 3, 5, 5, 6, 8, 8, 9, 10, 11, 11, 11, 12}
Answers
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

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

https://brainly.com/question/16645147?referrer=searchResults
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:
[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".

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
So the correct graph is the bottom left one

Using probability concepts, it is found that the matchings are:
Soft Drink - Likely.Dally Special - Unlikely.Dessert - Neither likely nor unlikely. Appetizer - very unlikely.------------------------
Probabilities assume decimal values between 0 and 1.The closer the probability is to 1, the more likely the event is to happen.------------------------
0.8 probability of a customers ordering a Soft Drink, which is a close value to 1, so Soft Drink - Likely.0.25 probability of a customer ordering a Dally Special, which is considerably less than 0.5, thus Dally Special - Unlikely.0.48 probability of a customer ordering a Dessert, which is around 0.5, thus Dessert - Neither likely nor unlikely.0.06 probability of a customer ordering an Appetizer, which is quite close to 0, so Appetizer - very unlikely.A similar problem is given at https://brainly.com/question/21408404

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

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.

Mrs. Smith's class is working on a variety of science experiments. Each
student must complete one experiment with each of the other students in
the class. There are 12 students in the class. How many different groups
will be made by the end of the experiments ? Each pair of students can
only be together once.
Answers
Answer:
66
Step-by-step explanation:
If there are n students, then the number of pairs is [tex]\frac{n(n-1)}{2}[/tex].
With 12 students, [tex]\frac{12(12-1)}{2} = \frac{132}{2}=66[/tex] pairs can be formed.
The reason the formula works is this: Each of the 12 students can be paired with 11 other students (no student is paired with him/her self). But counting 12 x 11 = 132 counts each pair twice. Example: student A can be paired with student B,..., student B can be paired with student A. The pair was counted two times.
See the attached image that shows pairings of 5 students. There are
5(5 - 1)/2 = 5(4)/2 = 10 pairs.
