Sloan [31]
B and a
barry=b
a=older bro

a is 3 more than 3b
a=3+3b
sum is 28
a+b=28
3+3b+b=28
3+4b=28
minus 3 both sides
4b=25
divide both sides by 4
b=6.25

a=3+3b
a=3+3(6.25)
a=3+18.75
a=21.75


barry=6.25 years
21.75 years=older bro

The issue of corporate tax reform has been cause for much debate in the United States. Among those in the legislature, 26% are R
Stells [14]

Answer:

<h2>Check the explanation.</h2>

Step-by-step explanation:

Let, the total population is 1000.

The number of republicans are 26% that is 260, Democrats are 63% that is 630 and Independents are 11% of 1000, that is 110.

20% of 260 = \frac{20\times260}{100} = 52 Republicans favor some type of corporate tax reform.

51% of 630 = \frac{51\times630}{100} = 321.3 .

29% of 110 = \frac{29\times110}{100} = 31.9.

Total number of people, who favor some type of corporate tax is (52 + 321.3 + 31.9) = 404.2 ≅404.

The required probability is \frac{321}{404}.
