A 320 meter long tightrope is suspended between two poles. Assume that the line has an equal chance of breaking anywhere along its length.

a. Determine the probability that a break will occur in the first 50 meters of the tightrope.

7-(-4) is 4 units from 7 in the negative direction.

The number line keeps going both ways. You can include 6, 7, and so on, all the way up to the hundreds, thousands, and beyond, because the set of natural numbers only extends to the right.

A number line is a diagram that shows numerical values along a straight line that can be drawn either horizontally or vertically. It's simple for us to compare and compute basic arithmetic operations on numbers when they are written down on a number line. A number line's origin is typically thought to be zero (zero). There are only positive numbers to the right of zero and only negative numbers to the left of zero.

therefore,

7 - (-4)

= 7 + 4

= 11

when we simplify the expression we get the answer as 11 units

the result is that 11 units is 4 units away from 7 in a negative direction.

Hence we get the complete sentence.

Answer:

2421 or 21

Step-by-step explanation:

Hello!

Consecutive odd integers are set of odd integers that come right after each other.

Let "C" be Caroline's age. Caroline's next older sibling would be C + 2, as odd integers come to every two numbers, and the next would be C + 4, and finally C + 6.

If we add up all the expressions, we should get 9696.

The solution to this question does not seem reasonable. I assume that the correct sum of the age should be 96, given 9696.

If this is the case, then Caroline's age would be 21, using the same general logic.

By elimination, the solution of the system of equations, 4x + 2y = 4 and 6x + 2y = 8, is (2 , -2).

A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.

There are three methods that can be used to solve system of equations.

1. Elimination

2. Substitution

3. Graphing

Using the elimination method, given two equations in x and y, a variable should be eliminated by adding/subtracting the two equations.

Subtracting the two equations will eliminate the variable y.

6x + 2y = 8     (equation 2)

4x + 2y = 4     (equation 1)

2x + 0y = 4

x = 2

Substitute the value of x to any of the two equations and solve for y.

6x + 2y = 8     (equation 2)

6(2) +2y = 8

2y = 8 - 12

2y = -4

y = -2

Hence, the solution of the system of equations is (2 , -2).

The solution to the given equation 3/7 divided by 11/21 = (3/7)x is x = 21/11.

Given the equation in the question;

3/7 divided by 11/21 = 3/7 x

3/7 ÷ 11/21 = (3/7)x

To divide two fractions, multiply the first fraction by the reciprocal of the second fraction.

3/7 ÷ 11/21 = (3/7)x

3/7 × 21/11 = (3/7)x

( 3 × 21 )/( 7 × 11 ) = (3/7)x

63/77 = (3/7)x

Remove the parenthesis

63/77 = (3/7) × x/1

63/77 = ( 3 × x )/( 7 × 1)

63/77 = 3x/7

Cross multiply

63 × 7 = 3x × 77

441 = 231x

231x = 441

Divide both sided by 231

231x/231 = 441/231

x = 441/231

x = 21/11

As women's coat comes in sizes 4,6,8 , or 10 in black, brown, ivory, and cinnamon , possibility of selection of different coats is equal to 16.

As given in the question,

Availability of size number in women's coat = 4, 6, 8, or 10

⇒N(S) =4

Availability of color in women's coat = black, brown, ivory, and cinnamon

⇒ N(C) =4

Possibility of selection of different women's coats = N(S) × N (C)

                                                                              =4 × 4

Probability is the degree to which an occurrence is likely to take place, as determined by the proportion of favorable examples to the total number of instances for which it is probable to have occurred.

Let's assume

1 - P(no one has the same sign) >= 0.5

P(two or more people have the same sign) = 1 - P(no one has the same sign)

= 1 - (12 / (12-n)) / 12^n

1-0.5=0.5 >= P (no one has the same sign) = 12/(12^n x (12-n))

The numeric values of the function f(x) = 5x - 7 are given as follows:

a) f(-2) = -17.

b) f(1/2) = -9/2.

To find the numeric value of a function, we replace each instance of the variable by the desired value.

For this problem, the function is not 100% visible from the picture, but we are going to suppose it is given by:

f(x) = 5x - 7.

At x = -2, the numeric value is:

f(-2) = 5(-2) - 7 = -10 - 7 = -17.

At x = 1/2, the numeric value is:

f(1/2) = 5(1/2) - 7 = 5/2 - 14/2 = -9/2.

We create a number line with a range from 0 to 1.0 and divide it into 5 equal segments to demonstrate the equality between 0.200 and 1/5.

The visual representation of numbers on a straight line, either horizontally or vertically, is known as a number line. When numbers are written down on a number line, it is straightforward for humans to compare them and perform basic arithmetic operations on them. One might assume that a number line starts at zero (0). There are only negative numbers to the left of zero and only positive numbers to the right of zero. In other words, as we move to the right on a number line, the value of the numbers increases. This shows that the numbers on the right are more numerous than those on the left.

Answer:

You will  need 12.5 gallons of the 22% salt solution and 7.5 gallons of the 38% of the salt solution

Step-by-step explanation:

.22x + .38(20 -x) = .28(20)  I want to clear the decimal, so I will multiple through by 100

100[.22x + .38(20-x)] = [.28(20)]100

22x + 38(20-x) = 28(20)  Distribute the 38

22x + 760 -38x = 560 combine the x's

-16x + 720 = 560 Subtract 720 from both sides

-16x = -200  Divide both sides by -16

x = 12.5
