Answer:

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=\frac{64}{100}\times10000=6400

Population was African-American=\frac{11}{100}\times 10000=1100

Population was Hispanic=\frac{10}{100}\times 10000=1000

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=\frac{86}{100}\times 6400

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=\frac{77}{100}\times 1100=847

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

Population of Hispanics used the Internet for e-mail=\frac{77}{100}\times 1000=770

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

Population of others used the Internet for e-mail=\frac{84}{100}\times 1500=1260

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

=\frac{Population \;of \;Hispanics \;used \;the \;Internet \;for \;e-mail}{total\;population\; used \;the \;Internet \;for\; e-mail}\times 100

Percentage of U.S resident who used the Internet for e-mail were Hispanic=\frac{770}{8381}\times 100

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

Equation using the quadratic fromula for 0.05x^2 + 1.1x = 250
Anuta_ua [19.1K]

Answer:

x=60.56, x=-82.56

Step-by-step explanation:

Solve using quadratic formula

Formula is

x=\frac{-b+-\sqrt{b^2-4ac}}{2a}

0.05x^2 + 1.1x = 250

Subtract 250 on both sides

0.05x^2 + 1.1x - 250=0

a= 0.05, b=1.1 , c=-250

Plug in the values in the formula

x=\frac{-1.1+-\sqrt{(1.1)^2-4(0.05)(-250)}}{2(0.05)}

x=\frac{-1.1+-7.156116265}{0.1}

Now make two equations , one with +  and one with -

then we solve for x

x=\frac{-1.1+7.156116265}{0.1}

x=60.56

x=\frac{-1.1-7.156116265}{0.1}

x=-82.56

What is 2\20 divided by 2
Valentin [98]
\frac{2}{20} \div 2 \\ \\  \frac{1}{10} \div 2 \\ \\  \frac{1}{10} \times  \frac{1}{2} \\ \\  \frac{1 \times 1}{10 \times 2} \\ \\  \frac{1}{20} \\ \\

The final result is: 1/20 or 0.05.
