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%
-43/204
Step-by-step explanation:
−5/12 × 17/17 + 7/34 × 6/6 =
= −85/204 + 42/204
= −85 + 42/204
= −43/204
The similar Triangle OPN and triangle LMN are similar have the ratio LM / MN = OP / NP
<h3>What are
similar figures?</h3>
Two figures are said to be similar if they have the same shape and the ratio of their corresponding sides are in the same proportion.
Triangle OPN and triangle LMN are similar, hence:
LM / MN = OP / NP
The similar Triangle OPN and triangle LMN are similar have the ratio LM / MN = OP / NP

Answer:
(2x-5)(3x-2)
Step-by-step explanation:
1)When factoring quadratic equations in for ax²+bx+c you need to separate the b term in a way that the two addends you separate it by should equal a•c. Just do trial and error. In this case you should get -4 and -15. Your separated equation should be:
6x²-4x-15x+10
2)now factor out a common factor from the first two terms and one from the last two terms you should have:
2x(3x-2)-5(3x-2)
3)finally rewrite this equation into two separate factors and you have your answer.
