Your friend says that the line with the equation 2x + 3y = 7 has a slope of 2. explain to them the error in their thinking.

Answers

Answer 1

Answer:

The error of their thinking is that they did not convert the equation to slope intercept form, so they assumed that the 2x was the slope. They got the standard form mixed up with slope intercept.

A subset of a statistical population called a simple random sample is one in which each member has an equal chance of being chosen.

What is Probability sampling?

A probability Slice is a process of opting for a sample from a population when the selection is grounded on the randomization principle, frequently known as chance or arbitrary selection. In general, a probability slice is more delicate, time-consuming, and precious than a non-probability slice.

A random/ arbitrary sample is similar to a straightforward arbitrary sample. The distinction between the two is that any object in the population has an equal probability of being named with a simple arbitrary slice. Every item doesn't inescapably have an equal chance of being chosen in an arbitrary slice.

A random/ arbitrary sample is one that was named at arbitrary. It should really be labeled as a sample that was chosen at arbitrary. In order to help bias and other negative goods, arbitrary samples are employed. In fact, it's not as easy as it seems to opt for a arbitrary sample that involves further than simply opting for 100 people from a population of 1000. Make sure your arbitrary sample is actually random/ arbitrary before using it.

What is Combinations?

Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant. You can choose the components of combos in any order. Permutations and combinations can be mixed up. The sequence in which the chosen components are chosen is crucial in permutations, too. For instance, the arrangements ab and ba are distinct in permutations but equivalent in combinations (regarded as one arrangement).

Combinatorics is the study of combinations, although mathematics and finance are two other fields that employ combinations.

EXPLNATION : For a handshake you need two people. Therefore, select two from twenty, that is, 20C2 ways. It is 20*19/2 = 190.

In general, if there are ’n’ number of people there can be nC2 handshakes.

How does probability explain work?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about how probable an event is to happen, or its chance of happening.Basic probability is governed by three primary rules: the addition rule, the multiplication rule, and the complement rule.Since there is a 50% chance that the outcome will be heads, we can anticipate 50 heads. But when we actually test it, we may get 48 heads, 55 heads, or anything else at all, though it will typically be a figure close to 50.

Based on the given conditions formulate = 28 + 5 * 4

Calculate the product or quotient = 28 + 20

What expression represents the length of the rectangle?
A rectangle with a width of x plus three and an unknown length. The area of the rectangle is x squared plus eight x plus fifteen.

Answers

The length of the given rectangle is x + 5 meters.

What is a rectangle?A rectangle is a quadrilateral with four right angles in the Euclidean plane. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal.

Given:

Area of rectangle  = x² + 8x + 15 sq.metersWidth = x + 3 meters

To find: Length of the rectangle

Finding:

Let 'a' be the length of the rectangle.

We know that area of a rectangle = length * width

On substituting the given values in the above formula, we get:

=>  x² + 8x + 15 = a (x + 3)

=> a = [tex]\frac{x^2+8x + 15}{x+3}[/tex]

=> a = [tex]\frac{(x+5)(x+3)}{x+3}[/tex]

=> a = x + 5

Hence, The length of the given rectangle is x + 5 meters.

To find: Length and Width.

Let the width of the rectangular play area be x.

Then, the length = 5x

According to the formula of perimeter of a rectangle,

100 = 2 (x + 5x)

=> 50 = 6x
