The measures of two complementary angles are represented by (2x) and (3x - 10)". What is the value of x?
raketka [301]

Answer:

Step-by-step explanation:

<u>2x + 3x</u> - 10 = 90

Combine like terms

5x - 10 = 90

Add 10  to both sides

5x = 90+10

5x = 100

Divide both sides by 5

x =100/5

x = 20

Find the 10th and nth term of each G.P.:5,25,125,.....​
RUDIKE [14]

Answer:

The n^{th} of the sequence

t_{n} = ar^{n-1}

The  10^{th} of the sequence

t_{10} = 5(5)^{10-1} =  9,765,625

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the geometric sequence

5, 25 , 125 ,....

First-term  a= 5

Difference    r = \frac{25}{5} =5

The n^{th} of the sequence

t_{n} = ar^{n-1}

The  10^{th} of the sequence

t_{10} = 5(5)^{10-1} =  9,765,625

A researcher conducted an Internet survey of 500 students at a particular college to estimate the average amount of money studen
bonufazy [111]

Answer:

The margin of error is  ME = 2.2962

Step-by-step explanation:

From the question we are told that

     The number of student is n = 500

     The highest amount is  A =$200

     The lowest amount is  B = $75

       The sample mean is  x = &140

The Standard deviation  of this set is mathematically evaluated as

            s =  \frac{A-B}{4}

Substituting values

            s =  \frac{200-75}{4}

            s = 31.25

The margin of error (ME) is mathematically evaluated as

            ME =  t_{n-1}__{\alpha }} *  \frac{s}{\sqrt{n} }

Where  t_{n-1}__{\alpha }} is the critical value for \alpha  = 0.05 i.e the significance level

     From the critical value table this is  t_{n-1}__{\alpha }}  =  1.649

So

       ME =  1.649  *  \frac{31.25}{\sqrt{500} }

      ME = 2.2962
