The given set ℤ can be written as {..., -3, -2, -1, 0, 1, 2, 3, ...}.

The given set ℤ can be written as { x | x is an integer, -∞ < x < ∞}.

Disclaimer:

I assume that ℤ in the question indicates the set of all integers.

Sets are the basis of mathematics. One can write sets in different ways and form smaller sets of elements from a larger set.

Any set can be written in two forms.

Roster form:

Roster form is one way to write sets. The roster form lists the elements of a set within braces, { }. Let's see a few examples for the roster form.

So, the given set ℤ can be written as {..., -3, -2, -1, 0, 1, 2, 3, ...}

Set-builder notation:

Set-builder notation is another way to write sets. Set-builder notation describes by enumerating its elements or stating the properties that its elements must satisfy. Let's see a few examples for the set-builder notation.

So, the given set ℤ can be written as { x | x is an integer, -∞ < x < ∞}. This is read as "the set of all real numbers x, such that x is an integer".

Answer:

Step-by-step explanation:

Given that [tex]2\frac 1 2 \div \frac 1 8 =20[/tex]

[tex]\Rightarrow \frac 5 2 \div \frac 1 8 =20[/tex]

[tex]\Rightarrow \frac 5 2 \times 8 1 =20 \cdots(i)[/tex]

Now, [tex]2\frac 1 2 \div \frac 5 8[/tex] [tex]= \frac 5 2 \div \frac 5 8[/tex][tex]=\frac 5 2 \times \frac 8 5[/tex]

This can be written as

[tex]\frac 5 2 \times \frac 8 5=\frac 5 2 \times \left( \frac 8 1 \times \frac 1 5\right)[/tex] [as [tex]\frac 8 5=\frac 8 1 \times \frac 1 5[/tex]]

[tex]=\left(\frac 5 2 \times \frac 8 1 \right)\times \frac 1 5[/tex]

[tex]=20 \times \frac 1 5[/tex] [ by using equation (i)]

=4

Hence, [tex]2\frac 1 2 \div \frac 5 8=4[/tex]

Answer:

Step-by-step explanation:

2x + -1y = -42

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'y' to each side of the equation.

2x + -1y + y = -42 + y

Combine like terms: -1y + y = 0

2x + 0 = -42 + y

2x = -42 + y

Divide each side by '2'.

x = -21 + 0.5y

Simplifying

x = -21 + 0.5y

The expression of the mathematical statement given as the product of 50 and the number of employees is 50x

The mathematical statement is given as

The product of 50 and the number of employees

The product of numbers means multiplication

So, we have

The product of 50 and the number of employees = 50 * the number of employees

Let number of employees be x

So, we have

The product of 50 and the number of employees = 50 * x

Evaluate the product

The product of 50 and the number of employees = 50x

Hence, the expression of the mathematical statement given as the product of 50 and the number of employees is 50x

On average, she digs 45 plants per week

Step-by-step explanation:

Here, we have the number of plants dug in every saturday for three weeks

we now want to get the average of the three weeks

We proceed to add up all what has been dug in the three weeks and divide by 3

Mathematically, that would be;

(42 + 60 + 33)/3 = 135/3 = 45

33+55

you would do 33+55

The school has a total enrollment of 2900.

A probability distribution that demonstrates that the likelihood of success is constant across trials is known as a: Uniform probability distribution

In uniform probability distributions, the likelihood of each possible outcome happening or not is the same. This property means that, for any given trial, the probability that an event will be successful does not change. Take the probability of rolling a 5 on a die for instance, no matter how many trials are performed, there is always a 1 in 6 probability for each trial.

Answer:

Step-by-step explanation:

75x + -300 = 25x + 200

Reorder the terms:

-300 + 75x = 25x + 200

Reorder the terms:

-300 + 75x = 200 + 25x

Solving

-300 + 75x = 200 + 25x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-25x' to each side of the equation.

-300 + 75x + -25x = 200 + 25x + -25x

Combine like terms: 75x + -25x = 50x

-300 + 50x = 200 + 25x + -25x

Combine like terms: 25x + -25x = 0

-300 + 50x = 200 + 0

-300 + 50x = 200

Add '300' to each side of the equation.

-300 + 300 + 50x = 200 + 300

Combine like terms: -300 + 300 = 0

0 + 50x = 200 + 300

50x = 200 + 300

Combine like terms: 200 + 300 = 500

50x = 500

Divide each side by '50'.

Based on the table on the amount of carrots and potatoes purchased, the cost of each pound of carrots and potatoes are Cost per pound of carrots: $1.50 and per pound of potatoes: $2.00

As you have been given options, you can use the prices in the options to see which price tallies with the total amount that each customer paid.

If you checked all the options, you would find the correct option is the correct option.

The first customer would pay:

= (4 x 1.50) + (6 x 2)

= $18

The second customer:

= (2  x 1.50) + (2 x 9)

= $21

These tally with the amounts paid by the customers so they are the prices of the unit pound of carrots and potatoes.

The fabric left is 2 1/4 yards which is calculated using subtraction.

Total fabric = 3 1/2 = 7 / 2 yards

Used fabric = 1 / 4 yards

Fabric left will be calculated using subtraction.

So, we get that:

Left fabric = 7 / 2 - 1 / 4

= 14 / 4 - 1 / 4

= 13 / 4

= 2 1/4 yards.

Therefore, we get that, the fabric left is 2 1/4 yards which is calculated using subtraction.
