A store sells peanuts by the pound. Jerry paid 4.59 for 5.4 pounds of peanuts. At that rate, how much would he pay for 7.8 pound
nikdorinn [45]
If $4.59 = 5.4 peanuts
         $x = 7. 8 peanuts

Cross multiply and you get:

5.4x = (4.59)(7.8)
      x = ((4.59)(7.8)) / 5.4
      x = $6.63

What is the lower quartile of the following set? 28, 45, 12, 34, 36, 45, 19, 20 28.5 19.5 19 28
aleksandr82 [10.1K]
To find the lower quartile take the number of terms=n=12
to find the lower quartile take the equation (n+1)/4= 3.25
this means that the lower quartile will be at the 3.25th position int he sequence when all the terms are ordered from smallest to largest. so when ordered: 12  19  19  19.5  20  28  28   28.5   34   36   45   45
so the lower quartile is between 19 and 19.5 exactly 19.125

U-5=-8 is tell solution of equation ​
ivanzaharov [21]

Answer:

u = -3

Step-by-step explanation:

Solve for u:

u - 5 = -8

Hint: | Isolate terms with u to the left hand side.

Add 5 to both sides:

u + (5 - 5) = 5 - 8

Hint: | Look for the difference of two identical terms.

5 - 5 = 0:

u = 5 - 8

Hint: | Evaluate 5 - 8.

5 - 8 = -3:

Answer: u = -3
