Solution

Given that the Perimeter is: 340 yards. Lenght is 91 yards

Since P = 2(L + W)

where L is the Length

W is the width

=> 340 = 2(91 + W)

=> 340 = 182 + 2W

=> 158 = 2W

Dividing both sides by 2

=> W = 79

Hence, the width is 79 yards

Answer: it would be 79yards

Step-by-step explanation: 91•2=182

340-182=158

158/2=79yards

Step-by-step explanation:

a) 5 digit zip code with no repeated digits

Firstly, there are 10 digits. After each digit in the zip code, one is used up.

The total number of zip codes possible is 10^5, or 100,000

The number of zip codes with no repeated digits can be found with:

(10-0)*(10-1)*(10-2)*(10-3)*(10-4)

which equals

10 * 9 * 8 * 7 * 6 = 30240

30240 divided by 100,000 is 0.3024

b) same process, but the numbers used are only 1-9.

(9-0)*(9-1)*(9-2)*(9-3)*(9-4) = 9 * 8 * 7 * 6 * 5 = 15120

15120 divided by 100,000 is 0.1512

c) back to using 1-10, but with a 1/10 chance for three digits

(10-0)*(10-1)*(1)*(1)*(1) = 8 * 9 = 90

90 divided by 100,000 is 0.0009

The probability of a 5-digit zipcode having no repeated digits is 0.3024, no 0's is 0.59049, and exactly two 1's and two 3's is 0.0012.

The probability of a 5-digit zipcode having no repeated digits, no 0's, and exactly two 1's and two 3's can be calculated using the formula for probability, which is P(event) = a number of favorable outcomes/number of possible outcomes.

(a) No repeated digits:

The number of favorable outcomes is 10*9*8*7*6 since there are 10 choices for the first digit, 9 for the second, 8 for the third, 7 for the fourth, and 6 for the fifth.

The number of possible outcomes is 10^5 since there are 10 choices for each of the 5 digits. Therefore, the probability is (10*9*8*7*6)/(10^5) = 0.3024.

(b) No 0's:

The number of favorable outcomes is 9*9*9*9*9 since there are 9 choices for each of the 5 digits (excluding 0).

The number of possible outcomes is 10^5 since there are 10 choices for each of the 5 digits. Therefore, the probability is (9^5)/(10^5) = 0.59049.

(c) Exactly two 1's and two 3's:

The number of favorable outcomes is 5*4*3*2*1 since there are 5 choices for the first 1, 4 for the second 1, 3 for the first 3, 2 for the second 3, and 1 for the remaining digit.

The number of possible outcomes is 10^5 since there are 10 choices for each of the 5 digits. Therefore, the probability is (5*4*3*2*1)/(10^5) = 0.0012.

Therefore, the probability is 0.0012.

Parallel lines are coplanar infinite straight lines in geometry that never intersect.

Lines that are always the same distance apart in a plane are said to be parallel. Lines that are parallel never cross. Lines that cross at a straight angle (90 degrees) are said to be perpendicular.

Parallel lines are a grouping of two or more lines that all lie in the same plane but never cross. Both of them have the same slope and are equally spaced apart. Let's read this article to learn more about parallel lines.

It is argued that two non-vertical lines in the same plane that have the same slope are parallel. It is impossible for two parallel lines to cross. Perpendicular lines are those that cross at a right angle when two non-vertical lines in the same plane.

The two equations are written as

7x + y = 5.

Martha's claim that the 25% of the learners are girls, is correct.

In this question,

There are 900 boys and 300 girls at Eqinisweni secondary school.

Martha claims that 25% of the learners are girls.

We need to verify her claim by means of calculations.

Based on the given conditions, we formulate:

300 / (900 + 300)

We simplify above expression.

= 300 / 1200

= 1/4               ..................(Cross out the common factor)

Now multiply a number 25 to both the numerator and the denominator:

= (1 × 25)/(4 × 25)

= 25/200

Now we rewrite a fraction with denominator equals 100 to a percentage: 25%

y=-2x+1

graph it.

Answer:

(3) y-3 = -2(x + 1)

Step-by-step explanation:

Lets change all equations to slope-intercept form to easily see the slope.

Slope-Intercept Form:

y = mx+b

M is slope, or the amount the y-value increases when the x-value increases by 1. B is y-intercept, or the y-value of the line when it is intersecting the y-axis (x=0).

#1: y + 5 = x - 3

Subtract 5 on both sides.

y + 5 - 5 = x - 5

Simplify.

y = x - 5

In slope intercept form. Slope of 1 and y-intercept of -5.

#2: y=2x+1

Already in slope intercept form. Slope of 2 and y-intercept of -5.

#3: y-3 = -2(x+1)

Use distributive property to simplify.

y - 3 = -2x-2

Add 3 on both sides.

y - 3 + 3 = -2x - 2 + 3

Simplify.

y = -2x+1

In slope intercept form. Slope of 2 and y-intercept of 1.

#4: y = x+2

Already in slope intercept form. Slope of 1 and y-intercept of 2.

Now using the slope formula, we can eliminate 2 possibilities.

Slope Formula: \(\frac{y_2-y_1}{x_2-x_1}\)

Plug in points.

\(\frac{3--5}{-1-3}\)

Simplify.

\(\frac{8}{-4}\)

Divide.

-2

Slope is -2. Because the slopes of #1 and #4 are 1 (not -2), they cannot be the equation that passes through the line. The slope of #2 is 2, not -2. We are left with: #3.

According to the proof, equal difference property is not satisfied by the function f(x).

There are four binary variables, x1, x2, x3, and x4.

The binary format is now converted to hexadecimal format, and the values are stored as A, B, C, and D, accordingly.

Convert every four bits of a binary value to a hexadecimal value.

ex: Split into 4 bits: x1 = 00000000 = 0000 0000 = 0 0 (convert the 4 bits to hex)

A = 00 ( hexadecimal of x1 )

B= 01 ( hexadecimal of x2 ) ( hexadecimal of x2 )

C=02 ( hexadecimal of x3 ) ( hexadecimal of x3 )

D=03 ( hexadecimal of x4 ) ( hexadecimal of x4 )

The function in question is f(x) = BS(x), which means that it performs byte alternation on the input x.

This means that f(x1) = 63, f(x2) = 7C, f(x3) = 77, and f(x4) = 7B.

We must now demonstrate that x1 xor x2 equals x3 xor x4 and that f(x1) xor f(x2) does not equal f(x3) xor f(x4) (x4).

If x1 xor x2 = 00, then xor 02 = 02 xor 01 = 01 x3 xor x4 03 = 01 So, x1 Equals x2 OR x3 OR x4 In the present, f(x1) xor f(x2) = 63 xor 7C = 1f f(x3) xor f(x4) = 77 xor 7B = 0C Due to f(x1) xor f(x2) not being equivalent to f(x3) xor f(x4).

Hence, the equal difference property is not satisfied by the function f(x), which is the Byte Substitution (BS) function of AES, according to the proof.

x2 | 0 1 4/7 3/14 -1/14 1/2

s2 | 1 0 3/7 -1/14 3/14 3/2

Z | 0

a) Writing the problem in equation form and adding slack variables:

Maximize Z = 3x1 + 2x2 + x3

Subject to:

3x1 - 3x2 + 2x3 + s1 = 3

-x1 + 2x2 + x3 + s2 = 6

x1, x2, x3, s1, s2 ≥ 0

b) Solving the problem using the simplex method:

Step 1: Convert the problem into canonical form (standard form):

Maximize Z = 3x1 + 2x2 + x3 + 0s1 + 0s2

Subject to:

3x1 - 3x2 + 2x3 + s1 = 3

-x1 + 2x2 + x3 + s2 = 6

x1, x2, x3, s1, s2 ≥ 0

Step 2: Create the initial tableau:

x1 x2 x3 s1 s2 RHS

s1 | 3 -3 2 1 0 3

s2 | -1 2 1 0 1 6

Z | 3 2 1 0 0 0

Step 3: Perform the simplex method iterations:

Iteration 1:

Pivot column: x1 (lowest ratio = 3/1 = 3)

Pivot row: s2 (lowest ratio = 6/2 = 3)

Perform row operations to make the pivot element equal to 1 and other elements in the pivot column equal to 0:

s2 = -s2/3

x2 = x2 + (2/3)s2

x3 = x3 - (1/3)s2

s1 = s1 - (1/3)s2

Z = Z - (3/3)s2

New tableau:

x1 x2 x3 s1 s2 RHS

x1 | 1 -2/3 -1/3 0 1/3 2

s2 | 0 7/3 4/3 1 -1/3 2

Z | 0 2/3 2/3 0 -1/3 2

Iteration 2:

Pivot column: x2 (lowest ratio = 2/7)

Pivot row: x1 (lowest ratio = 2/(-2/3) = -3)

Perform row operations to make the pivot element equal to 1 and other elements in the pivot column equal to 0:

x1 = -3x1/2

x2 = x2/2 + (1/7)x1

x3 = x3/2 + (4/7)x1

s1 = s1/2 - (1/7)x1

Z = Z/2 - (2/7)x1

New tableau:

x1 x2 x3 s1 s2 RHS

To calculate the probability of landing on a number less than 5 and then landing on a number less than 6, we need to determine the total number of favorable outcomes and the total number of possible outcomes.

Given the numbers 3, 4, 5, and 6, we have two favorable outcomes: landing on either 3 or 4 (both less than 5) and then landing on a number less than 6.

The total number of possible outcomes is 4 because we have four numbers in total (3, 4, 5, 6).

Therefore, the probability is given by:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 2 / 4

Probability = 1/2

So, the probability of landing on a number less than 5 and then landing on a number less than 6 is 1/2 or 0.5 (50%).
