A questionnaire has determined that 20% of the residents of Flaugamuck County own an iPod. Furthermore, 80% of these iPod owners
nydimaria [60]

Answer:

P = 7.14%

The percentage of those 30 years or older that own an ipod is 7.14%

Step-by-step explanation:

Given;

Percentage of ipod owners Pi = 20%

Percentage who don't own ipod Pd = 100-20 = 80%

For age 30 or older;

Percentage of ipod owners who belong to this group

Po = 20% of Pi

Percentage who don't have an ipod but belong to this group Pu = 100-35% = 65% of Pd

The percentage of those 30 years or older that own an ipod is;

P = Po/(Po+Pu) × 100%

Po = 20% of Pi = 20% of 20% = 0.2×20 =4%

Pu = 65% of Pd = 65% of 80% = 0.65×80% = 52%

Substituting the values;

P = 4/(4+52) × 100%

P = 7.14%

Math question help pls
valentina_108 [34]

Answer:

The fourth answer: A person's weight, w, on the moon is 1/6 her weight on Earth, e.

Step-by-step explanation:

The equation must be translated carefully into word form.

Her weight on Earth is represented by <em>e</em>.

"e x 1/6" into "1/6 her weight on Earth, e"

Her weight on the moon is represented by <em>w</em>.

"= w" into "A person's weight, w, on the moon is"

Another way to translate: 1/6 of a person's weight on Earth, e, is equal to her weight on the moon, w.

I hope this helped :)

Find the product. Multiplication of the binomial.
AnnZ [28]

We have, (2r+3)(3r^2+4r+5) or more generally,

(a+b)(c+d+e)=ac+ad+ae+bc+bd+be

So using that, we find,

(2r+3)(3r^2+4r+5)=6r^3+8r^2+10r+9r^2+12r+15, then collect terms with same exponent and get \boxed{6r^3+17r^2+22r+15}.
