Answer:

The probability of the tip to be more than 200 is 0.1.

Step-by-step explanation:

As per the given data

Amount of tip            Number

     0-20                       200

   20-50                       100

   50-100                      75

 100-200                     75

    200+                        50

____________________

Total=                         500

So what is the probability of tip to be more than 200 is given as

P(200+)=\frac{no. \, of\,occurrence}{Total\, Number}

From the table the value is 50 for the tip to be more than 200 where as the total occurrences are 500 so substituting values:

P(200+)=\frac{no. \, of\,occurrence}{Total\, Number}\\P(200+)=\frac{50}{500}\\P(200+)=0.1

So the probability of the tip to be more than 200 is 0.1.

Macario is making 12 pounds of nut mixture with macadamia nuts and almonds. Macadamia nuts cost $9 per pound and almonds cost $5
Fynjy0 [20]

Marcario should use  4 pounds of macadamia nuts and 8 pounds of almonds.

Explanation

given

cost of macadamia nuts per pound=$9

cost of almond nuts per pound=$5.25

cost of the mixture per pound=$6.5

total pounds of the mixture to be made=12

let the pounds of macadamia nuts=x

pounds of almond nuts=y

total pounds of nuts=x+y=12

x+y=12(1)\\9x+5.25y=6.5(x+y)\\\\9x+5.25y=6.5*12\\9x+5.25y=78(2)

solving (1) and (2)

x=4

y=8
