Answer: Pr= 42.9%

Step-by-step explanation:

SD = 4.2

Mean = 9.4

Which is between 5.2 - 13.6

Probability of at least 10lb is given by;

Pr= 13.6-10 / 13.6-5.2

Pr= 3.6/ 8.4

Pr= 0.4286× 100%

Pr= 42.9%

Anton [14]

Answer:

$283

Step-by-step explanation:

Let,

   x - for $2 notes

   x + 16 - for $5 notes

EQUATION:

  (x) + (x + 16) = 74

  2x = 74 - 16

  2x = 58

  x = 29

SUBSTITUTE

  x = 29 pieces of $2 notes

  x + 16 = 29 + 16 = 45 pieces of $5 notes

TOTAL VALUE IS:

   (29 x $2) + (45 x $5) = $283

One number is 2 more than 3 times another. Their sum is 22. Find the numbers.
ivolga24 [154]
Make a system of equations.

\sf~x=3y+2
\sf~x+y=22

Re-arrange the 2nd equation:

\sf~x+y=22

Subtract y to both sides:

\sf~x=-y+22

Plug in -y + 22 for 'x' in the first equation.

\sf~x=3y+2

\sf~-y+22=3y+2

Subtract 3y to both sides:

\sf~-4y+22=2

Subtract 22 to both sides:

\sf~-4y=-20

Divide -4 to both sides:

\sf~y=\boxed{\sf5}

Plug this into any of the two equations to find 'x':

\sf~x+y=22

\sf~x+5=22

Subtract 5 to both sides:

\sf~x=\boxed{\sf17}

So one of the numbers is 5 and one of them is 17.
