Answer:

The probability of getting a pair of red socks is 0.322

Step-by-step explanation:

According to the given data we have that A drawer contains 11 identical red socks and 8 identical black socks, hence, the total number of socks is 19, therefore, in order to calculate the probability of getting a pair of red socks we would have to use the following formula:

probability of getting a pair of red socks=11C2/19C2

probability of getting a pair of red socks=55/171

probability of getting a pair of red socks=0.322

The probability of getting a pair of red socks is 0.322

Here's what i did:

I broke down the fraction entirely.

3 / 5 = 6 / 10

divide 6 by two and divide 18 by two. This makes 3 / 10 = 9.

divide 3 by three and 9 by three, making 1 / 10 = 3.

if you need 7 / 10 of the number (30) then do 3*7.

The answer is 21.

Estimate the sum 7 8/9 + 3.1
Yanka [14]

Answer:

\large\boxed{7\dfrac{8}{9}+3.1=10\dfrac{89}{90}}

Step-by-step explanation:

\text{Convert the decimal to the fraction:}\\\\3.1=\dfrac{31}{10}=3\dfrac{1}{10}\\\\7\dfrac{8}{9}+3.1=7\dfrac{8}{9}+3\dfrac{1}{10}\\\\\text{The common denominator is 90.}\\90=9\cdot10\\\\7\dfrac{8}{9}=7\dfrac{8\cdot10}{9\cdot10}=7\dfrac{80}{90}\\\\3\dfrac{1}{10}=3\dfrac{1\cdot9}{10\cdot9}=3\dfrac{9}{90}\\\\\\7\dfrac{8}{9}+3.1=7\dfrac{80}{90}+3\dfrac{9}{90}=(7+3)+\dfrac{80+9}{90}=10\dfrac{89}{90}

3 (5 + 6)
ELEN [110]

Hi there!

Distributive property are two big words that basically just mean you need to distribute the 3 to the whole parentheses. This means you need to multiply 5 by 3 and also 6 by 3.

3 × 5 = 15

3 × 6 = 18


Now that you've distributed the 3 to the entire parentheses, you just need to add together both answers you got :

15 + 18 = 33


Your answer is: 33


There you go! I really hope this helped, if there's anything just let me know! :)

A community group is picking up trash along a portion of the highway that is 1.48 miles long. In one hour they can clean a secti
aleksklad [387]

Answer:

12 if im correct

Step-by-step explanation:

first we have to see that they are doing 1/8 of a mile per hour so if we divide 1.48 by 1/8 it should give us the time

first we convert 1/8 to a decimal which is .125 and we divide 1.48 by .125

giving us 11.84

since it is time, 11 hrs would be too little of a time so we need to round up to 12

Hope thats right
