### The tens digit of a number is twice the ones digit. The sum of the digit in the number 12. What is the number? X represents* 2x represents *

Let x = the ones digit
Let y = the tens digit

x+2y=12
x=2y
x+y=12 substitute x for 2y to get:
(2y)+y=12 add like terms to get:
3y=12
3y=12 divide both sides by 3 to get:
y=4
x+y=12 substitute y for 4 to get:
x+4=12 subtract 4 from both sides to get:

10(26 - h) + 100h = 1610
260 - 10h + 100h = 1610
-10h + 100h = 1610 - 260
90h = 1350
h = 1350/90
h = 15

t + h = 26
t + 15 = 26
t = 26 - 15
t = 11

### A cashier has a total of 26 bills made up of tens and hundreds the total value is 1610 how many hundreds and tens does she have?

Let the tens be x.

Therefore the hundreds will be (26 - x).

Since they both total to 26. x  + (26 - x) = 26

10*x + 100*(26 - x) = 1610

10x  + 2600 - 100x = 1610

10x - 100x = 1610 - 2600

-90x = -990

x = -990/-90

x = 11.

So the 10s are x =11,   the 100s  are (26 -11) = 15

11 tens bills and 15 hundred bills.

The equation for the line of best fit can be obtained as follows, using the least square method (for more info visit http://hotmath.com/hotmath_help/topics/line-of-best-fit.html ):

mean of X = 1/6
mean of Y = 2/3

slope, m = 704/1121 = 0.6

Computing the y-intercept using the formula:

b = mean of Y - m (mean of X) = 2/3 - (704/1121)(1/6)
b = 0.562 = 0.6

Therefore, the equation of the line of best fit, given the standard relation:

y = mx + b

### What is the probability of hitting each target if it is assumed that a player’s throw will always hit the board? hint: the probability of hitting each target is the area of the target hole divided by the total area of the target. take the value of π to be 3.14.

Because the actual dimensions of the board and the target are missing, let us supply the missing values.

Let:

radius of board = 6 inches
radius of target = 2 inches

Area of board = pi * r^2 = pi*6^2 = 36pi
Area of target = pi * r^2 = pi*2^2 = 4pi

Probability of hitting the target = 4pi / 36pi = 1/9

Therefore, there is a 1/9 chance of hitting the target on the board.

### Based on the data in the two-way table, what is the probability that a person weighs 120 pounds, given that he or she consumes 2,000 to 2,500 calories per day?

In the question "Based on the data in the two-way table, what is the probability that a person weighs 120 pounds, given that he or she consumes 2,000 to 2,500 calories per day?" The probability of an event, say A given another event, say B is given by n(A and B) / n(B). Thus the probability that a person weighs 120 pounds, given that he or she consumes 2,000 to 2,500 calories per day is given by number of persons that weigh 120 pounds and consume 2,000 to 2,500 calories per day / number of persons that consume 2,000 to 2,500 calories per day. From the table, the number of persons that weigh 120 pounds and consume 2,000 to 2,500 calories per day is 10 while the number of persons that consume 2,000 to 2,500 calories per day is 110. Therefore, the required probability is 10 / 110 = 1 / 11
