In a certain year, 86% of all Caucasians in the U. S., 77% of all African-Americans, 77% of all Hispanics, and 84% of residents not classified into one of these groups used the Internet for e-mail. At that time, the U. S. population was 64% Caucasian, 11% African-American, and 10% Hispanic. What percentage of U. S. residents who used the Internet for e-mail were Hispanic

Percentage of U.S resident who used the Internet for e-mail were Hispanic=9.19%

Step-by-step explanation:

We are given that

Population was Caucasian=64%

Population was African-American=11%

Population was Hispanic=10%

Let the population of U.S=10000

Now,

Population was Caucasian=

Population was African-American=

Population was Hispanic=

Population of others=10000-(6400+1100+1000)=1500

Population of Caucasians used the Internet for e-mail=86% of 6400

Population of Caucasians used the Internet for e-mail=

Population of Caucasians used the Internet for e-mail=5504

Population of African-American used the Internet for e-mail=77% of 1100

Population of African-American used the Internet for e-mail=

Population of Hispanics used the Internet for e-mail=77% of 1000

Population of Hispanics used the Internet for e-mail=

Population of others used the Internet for e-mail=84% of 1500

Population of others used the Internet for e-mail=

Total population used the Internet for e-mail=5504+847+770+1260

Total population used the Internet for e-mail=8381

Percentage of U.S resident who used the Internet for e-mail were Hispanic

=

Percentage of U.S resident who used the Internet for e-mail were Hispanic=

Percentage of U.S resident who used the Internet for e-mail were Hispanic=9.19%
