What is the probability that a randomly selected person surveyed has a job, given that the person is less than 18 years old? Exp
weeeeeb [17]

When the person is less than 18 years old, out of 265 persons, 20 has job and 245 do not have job.

The probability is defined as \frac{no\;of \; favourable \;outcomes}{total\;number\;of\;outcomes}.

Consider the first column only.

The probability that a randomly selected person surveyed has job is

\frac{20}{20+245} =0.0755

Nancy’s nut store sells peanuts for $2 per pound and cashews for $10 per pound. The store sells a peanut - cashew mixture for $7
Gelneren [198K]

9514 1404 393

Answer:

  • 25 pounds cashews
  • 15 pounds peanuts

Step-by-step explanation:

Let c represent the number of pounds of cashews in the mix. Then 40-c is the number of pounds of peanuts. The total cost of the mix is ...

  10c +2(40 -c) = 7(40)

  8c +80 = 280 . . . . simplify

  c +10 = 35 . . . . . . . divide by 8

  c = 25 . . . . . . . . . . subtract 10

  40-c = 40-25 = 15 . . . . pounds of peanuts

25 pounds of cashews and 15 pounds of peanuts should be used in the mix.

URGENT: Create a linear system whose ONLY SOLUTION is (3,13) . I just need the equations for f(x)=? , G(x)=? To get (3,13). ASAP
Otrada [13]

The solution of (3,13) means you need to create two lines that satisfy x = 3 and y = 13

The two lines can be anything as long as they give this solution

For example, if you wrote x + y = 16 (you know their values already)

Then write another y - x = 10

From here you have your equations, turn them into the f(x) form.

x + y = 16 can be turned into y = 16 - x which is f(x)=16-x

y-x = 10 can be turned into y = 10 + x which is g(x)=10 + x
