What is the answer to <br> 3/4 of 200
r-ruslan [8.4K]
3/4 = 0.75 or 75%. So you need to find 75% of 200... Simply multiply 0.75 or 3/4 by 200 and you will get your answer... (0.75)(200) = 150....

You could also realize with this problem that 3/4 of 200 is 150 because 50 goes into 200 4 times. 50 = 1/4, 100 = 2/4 = 1/2, 150 = 3/4 & 200 = 4/4 = 1.

U.s employes received 3% raise in 2012. Suppose an employee made 47,000 in 2011 and received a 3% raise what she did make in 201
n200080 [17]
It would be: 47000 + (47000 * 3%)
= 47000 + (47000 * 0.03)
= 47000 + 1410
= 48410

In short, Your Answer would be $48410

Hope this helps!

PLEASE HELP<br><br><br> Solve.<br><br> 5x+2/2 = 2x - 1<br><br> X = ________ ?
lakkis [162]
5x + 2/2 = 2x - 1
2/2 is basically 1 so
5x + 1 = 2x - 1
isolate the variable
5x + 1 = 2x - 1
      -1          -1
5x = 2x -2
-2x   -2x
3x = -2
solve
3x/3=-2/3
x=-2/3

Using a calculator, it is found that the correlation coefficient for this data is given by:

B. -0.901.

<h3>What is a correlation coefficient?</h3>

  • It is an index that measures correlation between two variables, assuming values between -1 and 1.
  • If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
  • If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.

To find the coefficient, which has symbol r², we input in a calculator the values of x and the values of y, hence:

r² = -0.901.

Which means that option B is correct.
