Hey there!

If x = 3 then substitute it into the equation

3(3) = 9

3(3) = 9

9 = 9

If stratified random sampling with proportional allocation is used to select a sample of 25 high​ schools, how many would be sel
gregori [183]

Answer:

02 High Schools would be selected from the stratum with a​ percent-free-lunch value of 40 less than or equals x​.

Step-by-step explanation:

As the sample size needed is 25 and total schools are 100 so this indicate 1 school in each 4 schools is to be selected. This is given as

n=\frac{n_{total}}{n_{sample}}\\n=\frac{100}{25}\\n=4

Now as the schools with percent free lunch are 8 so now

n=\frac{n_{total}}{n_{sample}}\\n=\frac{8}{2}\\n=2

So only 2 schools will be selected in this regard.

Which expressions are equivalent to the one below? Check all that apply. <br><br> 9^x
AveGali [126]

Answer:

A) 3^{x}*3^{x}

B) 3^{2x}

C) (3 * 3)^{x}

Step-by-step explanation:

Given the exponential expression, 9^{x}:

A)  3^{x}*3^{x} is equivalent to 9^{x} due to the Product Rule of exponents:  a^{m} a^{n} = a^{m + n}.  

  • 3^{x}*3^{x} = 3^{x+x} = 3^{2x}

Next, apply the Power-to-Power Rule of exponents:  a^{mn} = (a^{m} )^{n}.  

  • 3^{x}*3^{x} = 3^{x+x} = 3^{2x} = (3^{2})^{x}  = 9^{x}

B)   3^{2x}  is equivalent to 9^{x} due to the Power-to-Power Rule of exponents:  a^{mn} = (a^{m} )^{n}.  

  • 3^{2x} = (3^{2})^{x} = (9)^{x} = 9^{x}.    

C)  (3 * 3)^{x}  is equivalent to 9^{x} due to the Product-to-Power Rule of exponents:  (ab)^{m} = a^{m} b^{m}.  

  • (3 * 3)^{x} = (9)^{x}  = 9^{x}
