The Consumer Price Index is calculated through the equation,
                             CPI = (current period price/base period price) x 100
The base period is 1983. Solving the CPIs for 2000 and 2005
         (2000) 
                             CPI = ($28.94/$16.35) x 100 = 177
        (2005)           
                             CPI = ($32.54/$16.35) x 100 = 199
The difference between the CPIs of 2005 and 2000 is 199 - 177 = 22.

Write in standard form the equation of a line with a slope of -3/5 and a y intercept of -3
Vlada [557]

Answer:

5y+3x=-9

Step-by-step explanation:

Let us start by the general form of the standard equation, Ax+By=C. One way we can solve this problem is by finding the <u>slope-intercept form</u> of this equation, y=mx+b, and converting it into the standard equation. In the slope-intercept form, m represents the slope, b represents the y intercept.

From this problem, we are given both the slope and the y intercept. We know have the equation:

y=-\frac{3}{5}x -3

Great! Now let us rearrange the terms so that the y and x terms are on one side of the equation.

y+\frac{3}{5} x=-3

This seems right, but a standard equation must have coefficient values that are real numbers. So, A and B must be real numbers. We can do this by multiplying the entire equation by 5 and ridding the denominator of the A term.

5y+3x=-9

Karen wants to estimate the mean number of siblings for each student in her school. She records the number of siblings for each
Tamiku [17]

The sample is 200 randomly selected students.

The following things should be considered:

  • Let us assume the no of siblings for each student be x.
  • Now for determining the mean no of siblings she choose 200 students.

So, here the sample should be 200 randomly selected students.

Therefore the other options should be incorrect.

Thus we can conclude that the sample is 200 randomly selected students.
