What is the differnce between ║-3║ and - 3.
Deffense [45]

Answer:

l-3l=3 and -3=-3

Step-by-step explanation:

The two bars mean you are finding the absolute value of a number. Absolute value is the distance from zero a number is. Since distance is always positive it basically just means take away the negative if there is one. For example,

l-7l=7 and l8l=8. So the difference is -3 is negative while l-3l is positive.

sertanlavr [38]

Answer:

let he invest x part of earning at the rate of 8%

simple interest = P*T*R/100 = x*1*8/100 = 0.08x

His invest at the rate of 7.5% = 3050 - x

Again simple interest = P*T*R/100 = (3050 - x)*1*7.5/100 = 228.75 - 0.075x

N0w acc0rding to question

0.08x + 228.75 - 0.075x = 242

0.005x= 13.25

x = 2650

Give one real life example of each correlation: positive, negative, and no correlation.
mixer [17]
In a positive correlation, both variables increase together. An example of this is a company's profit's relationship with its sales. The greater the sales, the greater the profit.
A negative correlation is where one variable decreases with increase in the other. An example is the time taken to reach somewhere and the speed traveled at. The faster you move, the less the time.
No correlation means the two variables are not related. An example of this is as you get older, it does not mean you will get better grades.
