____ [38]

Answer:

Kayla plays on average 0.2 more chess games than Becker

Step-by-step explanation:

The first thing we must do is calculate the mean of each one.

Becker:

(5 + 2 + 4 + 1 + 1 + 4 + 5 + 3 + 2 + 1) / 10 = 2.8

Kayla:

(2 + 3 + 1 + 1 + 4 + 1 + 5 + 3 + 5 + 5) / 10 = 3

if we subtract these averages, we have to:

3 - 2.8 = 0.2

which means that Kayla plays on average 0.2 more chess games than Becker. Since it is not even a complete game, the difference between the two is very small and almost irrelevant.

How many pounds of chamomile tea that costs $18.50 per pound must be mixed with 18 lb of orange tea that costs $12.23 per pound

Rasek [7]

Answer:

The amount of chamomile tea that has to be used in order to obtain a mixture that costs $14.32 per pound is 8.997 pounds

Step-by-step explanation:

In order to find out the amount of chamomile tea that must be used in the mixture to obtain a 14.32 $ per pound, we can use an weighted average where the price points for each kind of tea are the weights and "c" is the amount of chamomile that we have to use in order to obtain the price per pound that we want. So we have:

(18.5*c + 12.23*18)/(c + 18) = 14.32

18.5*c + 220.14 = 14.32*(c+18)

18.5*c + 220.14 = 14.32*c + 257.76

18.5*c - 14.32*c = 257.75 - 220.14

4.18*c = 37.61

c = 8.997 lb

Ann invested $61,000 into two accounts. The first account pays an annual interest rate of 5% and the second account pays an annu

sp2606 [1]

Answer:

2nd Account has $19,000

1st Account has $42,000

Step-by-step explanation:

First let's split the money invested.

x is money in account 1

y is money in account 2

1st equation

5%=0.05

7%=0.07

2nd equation

<u>0.05*x+0.07*y=$3,430</u>

x=61,000-y

substitute into 2nd equation

0.05(61,000-y)+0.07y=3430

Solve.

3050-0.05y+0.07y=3430

0.02y=3430-3050

0.02y=380

y=380/0.02

y=$19,000

There are 2(two) ways to solve for the 1st account, but I will do it the long way.

y=61,000-x

substitute into 2nd equation

0.07(61,000-x)+0.05x=3430

Solve.

4270-0.07x+0.05x=3430

-0.02x=3430-4270

-0.02x=-840

x=-840/-0.02

x=$42,000

The short way...

x=61,000-y

x=61,000-19,000

x=$42,000

Two points are selected randomly on a line of length 32 so as to be on opposite sides of the midpoint of the line. In other word

Paladinen [302]

Solution :

Let us consider the squares be $[1, 16] \times [16, 32]$

If x ranges from the 0 to 16 and the y ranges from 16 to 32, we see that the boundary of the region $y-x \geq 9 \text{\ is}\ y - x = 9$ which goes from the $(7, 16 ) \text{ to}\ (16, 25)$ .

And so it is easier to find the area of region where $y-x \leq 9$ . This is the triangle with points $(7,16),(16,25) \text{ and}\ (16,16)$ as its vertices.
