The first step to solving an equation like this is to find the slope of a line that will be perpendicular to the line given. The slope of a line that's perpendicular to another line is the negative reciprocal. The negative reciprocal of -1/5 is 5. So, so far our equation is y = 5x + b. Now, to find what b is equal to, we should substitute the values of x and y from the point (1,2) since we know that our line goes through the point. Our equation becomes:
2 = 5 + b
b= -3
That means that the equation of our new line is y = 5x - 3
Subtract the year you were born in from this year.
2017 - 1965 = 52
And since May already passed (05/22), you're birthday already passed.
So you are 52 years old if you were born in 05/22/1965.
Answer:
$16.67
Step-by-step explanation:
-Let Ben's expenditure be X,
#Ava's expenditure being three times Ben will be 3X, and half as much as Cora(2X)
-Given that the total expenditure was 50, Cora's portion is calculated as :
![Total=E_a+E_b+E_c\\\\50=2X+3X+X\\\\50=6X\\\\X=\frac{50}{3}\\\\E_c=2X=2\times \frac{50}{3}=16.67](https://tex.z-dn.net/?f=Total%3DE_a%2BE_b%2BE_c%5C%5C%5C%5C50%3D2X%2B3X%2BX%5C%5C%5C%5C50%3D6X%5C%5C%5C%5CX%3D%5Cfrac%7B50%7D%7B3%7D%5C%5C%5C%5CE_c%3D2X%3D2%5Ctimes%20%5Cfrac%7B50%7D%7B3%7D%3D16.67)
Hence, Cora's expenditure is $16.67
Answer:
There are many centeral tendancy like in pie charts, data handling etc. But i think ur asking abt this.. -
- Mean : It is the average ex : 5,5,2 : 5+5+2 /3 = 4
- Median: the middle number (arrange in asc or des order) then find the middle num if there are 2 middle num then find the mean of the 2
ex : 3,4,1,2,5 : 1,2,3,4,5, the middle is 3
-Mode : It is the data that is happening the most frequent
ex: 1,2,2,3,3,3,4,4,5 : 3
Ihope this is usefull !
