Pick a uniformly chosen random point inside a unit square (a square of sidelength 1) and draw a circle of radius 1/3 around the

Tresset [83]

Answer:

the probability is 4/9 (44,44%)

Step-by-step explanation:

Assuming that each point inside the square is equally probable, then the probability is uniformly distributed in area of the square. Thus

probability = area where condition is true / total area of the square

for a circle of radius 1/3 inside the square ,the area where this condition is satisfied is a square with sides 1-1/3 = 2/3 , thus

probability = (2/3)²/1² = 4/9

thus the probability is 4/9 (44,44%)

There are 8 rows and 8 columns, or 64 squares

lawyer [7]

Complete Question:

There are 8 rows and 8 columns, or 64 squares on a chessboard.

Suppose you place 1 penny on Row 1 Column A,

2 pennies on Row 1 Column B,

4 pennies on Row 1 Column C, and so on …

Determine the number of pennies in Row 1

Determine the number of pennies on the entire chessboard?

Answer:

255 in the first row

18,446,744,073,709,551,615 in the entire board

Step-by-step explanation:

Given

$Rows = 8$

$Columns = 8$

Solving (a): Number of pennies in first row

The question is an illustration of geometric sequence which follows

$1,2,4....$

Where

$a =1$ --- The first term

Calculate the common ratio, r

$r = \frac{T_2}{T_1} = \frac{4}{2} = 2$

The number of pennies in the first row will be calculated using sum of n terms of a GP.

$S_n = \frac{a(r^n - 1)}{n - 1}$

Since, the first row has 8 columns, then

$n = 8$

Substitute 8 for n, 2 for r and 1 for a in $S_n = \frac{a(r^n - 1)}{r - 1}$

$S_8 = \frac{1 * (2^8 - 1)}{2 - 1}$

$S_8 = \frac{1 * (256 - 1)}{1}$

$S_8 = \frac{1 * 255}{1}$

$S_8 = 255$

Solving (b): The entire board has 64 cells.

So:

$n = 64$

Substitute 64 for n, 2 for r and 1 for a in $S_n = \frac{a(r^n - 1)}{r - 1}$

$S_{64} = \frac{1 * (2^{64} - 1)}{2 -1}$

$S_{64} = \frac{(2^{64} - 1)}{1}$

$S_{64} = \frac{(18,446,744,073,709,551,616 - 1)}{1}$

$S_{64} = \frac{18,446,744,073,709,551,615}{1}$

$S_{64} = 18,446,744,073,709,551,615$

You are putting away money to spend at the school carnival. On day 6, you had $5. You were able to save

skad [1K]

Answer:

We have the equation of the line as;

y = 1.80x - 5.80

Step-by-step explanation:

Let us have a plot of the amount saved in dollars to the day number

So we have the amount as y axis values and the day as x axis values

from the question, we can identify the points as;

(6,5) and (11,14)

Mathematically the equation of a straight line can be represented by the equation;

y = mx + b

where m is the slope and b is the y intercept

So, we calculate the slope using the two points above

We have the formula as;

m = (y2-y1)/(x2-x1)

(x1,y1) = (6,5)

(x2,y2) = (11,14)

m = (14-5)/(11-6) = 9/5 = 1.8

So we have the equation as;

y = 1.80x + c

To get the value of c, we use any of the two points

Let us use the point (6,5)

we substitute 6 for x and 5 for y

So, we have ;

5 = 1.8(6) + c

c = 5-1.8(6)

c = -5.8

So we have the equation as;

y = 1.80x - 5.80
