pychu [463]

Answer:

17/12 = 1 5/12

Step-by-step explanation:

The common denominator of 4 and 3 is 12.

The equivalent fraction of 3/4 is 9/12.

The equivalent fraction of 2/3 is 8/12.

Their total is 17/12 (or 1 5/12).

The Table Shows a proportional relationship between x and y for each Value of x and y match it to the correct unit rate y/x in i
Elden [556K]

The correct proportions are given as follows:

  • x = 3, y = 27: 9/1.
  • x = 9, y = 81: 9/1.
  • x = 21, y = 126: 6/1.
  • x = 14, y = 84: 6/1.
  • x = 12, y = 36: 3/1.
  • x = 15, y = 45: 3/1.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The proportions for this problem are given dividing y by x, hence:

  • x = 3, y = 27: 27/3 = 9, hence 9/1 has to be marked.
  • x = 9, y = 81: 81/9 = 9, hence 9/1 has to be marked.
  • x = 21, y = 126: 126/6 = 6, hence 6/1 has to be marked.
  • x = 14, y = 84: 84/14 = 6, hence 6/1 has to be marked.
  • x = 12, y = 36: 36/12 = 3, hence 3/1 has to be marked.
  • x = 15, y = 45: 45/15 = 3, hence 3/1 has to be marked.

the linearized regression equation for an exponential data set is log y=0.23 + 0,08, where x is the number of years and y is the
irga5000 [103]

Answer:

Population = 691.83 (rounded = 692)

Step-by-step explanation:

The equation is:

Logy=0.23x+0.08

When there is no base written with log, we assume "base 10", so we can say:

Log_{10}y=0.23x+0.08

Now, we need to find the population (y) when x = 12. Lets plug in 12 into x:

Log_{10}y=0.23x+0.08\\Log_{10}y=0.23(12)+0.08\\Log_{10}y=2.84

Now, we change to exponential form by using the formula shown below:

Log_{10}x=b\\10^b=x

So, we have:

Log_{10}y=2.84\\y=10^{2.84}

Evaluate using calculator to get:

y=10^{2.84}\\y=691.83

The population after 12 years, would be 691.83, rounded, 692
