A researcher is exploring the notion that there is an economy of scale in raising children. While having one child might add to

a family's financial stress, the second or third one might not be as "expensive" since they would already be sharing one roof, could share clothing, etc. The researcher has access to a large community of parents where 15% have one child under 18 in their home, 65% of parents have two children, and 20% of parents have three or more children. Rounded to the nearest whole number, the probability that any given family who is selected has two or more children at home is ________ %?

Answer:

The probability is   G  =  85%

Step-by-step explanation:

From the question we are told that

   The percentage of parents that have one child under 18 in their homes is  k = 15%

  The percentage of parents that have two children is  T = 65%

    The percentage of parents that have three or more children is  Y = 20%

Generally the probability that any given family who is selected have two or more children at home is mathematically evaluated as

     G  =  T  +  Y

=>  G  =  65% +  20%

=>  G  =  85%

45%, 15%, 40%, 80%, 65%, 30%, 90%, 25% Do any of these percentages match the fraction 2/5?
Slav-nsk [51]

Answer:

Yes, the third option (40%)

Step-by-step explanation:

Given the fraction with numerator 2 and denominator 5:

\frac{2}{5}

You can convert it from this fraction form  to a decimal number by dividing the numerator 2 by the denominator 5, obtaining the decimal number:

\frac{2}{5}=0.4

Finally, to rewrite this decimal number to percentage, you need to multiply it by 100. Then:

0.4*100=40\%

Therefore, there is a percentage that matches the fraction \frac{2}{5}. This percentage is 40%, which corresponds to the third option.

Use the distributive property to write an equivalent expression.<br> 9(9x+2y-6)
Marizza181 [45]

Step-by-step explanation:

Multiply the number outside the brackets to the numbers inside:

So,

9 * 9x = 81x

9 * 2y = 18y

9 x -6 = -54

So the simplified or equivalent expression is:

81x + 18y - 54
