NikAS [45]

Answer:

The frequency table is attached below.

Step-by-step explanation:

Given the total number of candies in the box = 18

Frequency table is used to list the occurence of a thing or product and it helps to calculate and sort down easily.

                                 <u>Contains caramel</u>   <u>Do not contain caramel</u>    Total

<u>Contains chocolate</u>                    10                                   2                       12

The center of a circle is located at (3, 8), and the circle has a radius that is 5 units long. What is the general form of the e
lana [24]
First we write equation that consist  coordinates of center and radius. That formula goes like this:
(x-x1)^2 + (y-y1)^2  = r^2

x and y are coordinates on any point on circle
x1 and y1 are coordinates of center of circle.
r is radius of that circle. now we need to express our values for center and radius andf square binoms and see what matches in our options.

(x-3)^2 + (y-8)^2 = 5^2
x^2 + y^2 -6x -16y +48 = 0

The answer is first option.

A grocer bought some walnuts for 45¢ per pound and some pecans for 60¢ per pound. He wants to mix the pecans and walnuts togethe
ladessa [460]
Cost of walnuts = 45 cents per pound
Weight of walnuts in mixture = x pounds

So, total cost of walnuts in the mixture = 45x
This gives the cost in cents. The cost in dollars will be = 0.45x

Cost of pecans = 60 cents per pound

Since total weight of the mixture is 90 pounds. The weight of pecans in the mixture will be (90 - x) pounds.

So, total cost of pecans in the mixture will be = 60 (90 - x)
This gives the cost in cents, the cost in dollars will be = 0.6 (90 - x)

x pounds of walunts and (90-x) pounds of pecans are mixed to produce a mixture to sell at 55 cents per pound. So,we can set up the equation for this case as:

Cost of Walnuts + Cost of Pecans = Cost of Mixture

0.45x+(90-x)*0.60=90(0.55)

Using this equation, we can find the weight of walnuts, using x we can also find the weight of pecans. From weights we can then calculate the cost of walnuts and pecans used in the mixture.
