Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Jazz earns $12 per hour babysitting for her cousins every Friday. If she babysits for 5 hours, her total earnings would be:

Total earnings = Earnings per hour x Number of hours babysitting

Total earnings = $12/hour x 5 hours

Total earnings = $60

However, Jazz also spends $3 each for taking the bus to her cousins' place and another $3 for taking the bus back home. So her total expenses for transportation would be:

Total transportation expenses = $3 + $3 = $6

To calculate Jazz's net earnings, we subtract her total transportation expenses from her total earnings:

Net earnings = Total earnings - Total transportation expenses

Net earnings = $60 - $6

Net earnings = $ 54

Hence , Jazz would make $ 54 if she babysits for 5 hours after deducting her transportation expenses

Students should be able to apply these concepts and tools in real-world situations, such as calculating the probability of winning a game or analyzing data from a scientific Experiment.

The probability is a measure of the possibility of an event happening. It is expressed as a fraction or decimal between 0 and 1, or as a percentage between 0% and 100%. Probability can be used to determine the likelihood of an event happening or not happening.

Data analysis is the process of analyzing data to extract valuable insights from it. It involves examining data sets to uncover trends, patterns, and relationships that can be used to make informed decisions. Data analysis is an important tool in many fields, including business, finance, and science.

The data analysis and probability unit test assesses students' understanding of these concepts and their ability to apply them in real-world situations.

The test typically includes questions that require students to use probability to determine the likelihood of an event happening or not happening, as well as questions that ask students to analyze data sets to extract valuable insights.In order to prepare for the data analysis and probability unit test, students should review the key concepts and formulas related to probability, such as the addition rule, the multiplication rule, and the complementary rule.

They should also practice analyzing data sets using tools like histograms, scatter plots, and box plots, and should be familiar with key concepts like mean, median, and mode.

The best interpretation of the statement "the chances of winning a prize are 1 out of 10" is that if many people buy a ticket, about 1 in 10 will win.

This statement means that for every 10 tickets sold, on average, only one ticket will win a prize. It does not guarantee that you will win a prize if you buy a single ticket or even several tickets. The probability of winning a prize remains the same for every ticket purchased. It is important to note that winning a prize in a lottery is largely a matter of luck, and the odds are always against the player. While buying more tickets may increase your chances of winning, it does not guarantee a win.

The height of the screen will be;

⇒ h = 28 inches

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

A flat screen television is a rectangle with a 53-invh diagonal and a width of 45 inches.

Here,

The diagonal of the screen television = 53 inches

And, The width of the screen television = 45 inches

Let the height of the television = h

So, By the Pythagoras theorem, we get;

⇒ AC² = AD² + DC²

Where, AC = Diagonal of television.

AD = Height of the television

DC = Width of the television.

Substitute all the values, we get;

⇒ 53² = h² + 45²

⇒ 2809 = h² + 2025

⇒ 2809 -2025 = h²

⇒ h² = 784

⇒ h = √784

⇒ h = 28 inches

Thus, The height of the screen = 28 inches

The amount of patties she has needs to be greater than 40, and she already has 4 in her freezer. So these 4 added to how many she buys at the store (which come in packs of 6) have to be greater than 40.

Divide 6 on both sides using the simplified version,  p ≥ 6.

Answer:

Step-by-step explanation:

The probability of drawing one black ball and one white ball in two consecutive draws from the urn is approximately 0.42.

To calculate the probability of drawing one black ball and one white ball in two consecutive draws, we need to consider the outcomes of each draw.

In the first draw, there are 10 balls in total (3 black and 7 white). The probability of drawing a black ball on the first draw is 3/10, and the probability of drawing a white ball is 7/10.

For the second draw, after removing one ball from the urn, there are now 9 balls left. The probability of drawing a black ball on the second draw, given that a black ball was drawn on the first draw, is 2/9. Similarly, the probability of drawing a white ball on the second draw, given that a white ball was drawn on the first draw, is 6/9.

To calculate the overall probability, we multiply the probabilities of the individual events. The probability of drawing one black ball and one white ball in two consecutive draws is (3/10) * (6/9) + (7/10) * (2/9) ≈ 0.42.

Therefore, the probability of getting one black ball and one white ball in two consecutive draws from the urn is approximately 0.42.

The value of x from given quadrilateral ABCD is 27°.

In the given quadrilateral ABCD, ∠A=3x+5, ∠B=2x+15, ∠C=4x and ∠D=4x-10.

We know that, the sum of interior angles of quadrilateral is 360°.

Here, ∠A+∠B+∠C+∠D=360°

3x+5+2x+15+4x+4x-10=360°

13x+10=360°

13x=350°

x=350/13

x=26.9

The exact lengths of the missing sides for the right triangle using trigonometric ratio of the respective angles are: a = 4, b = 4√3, c = 4√3, and d = 4√6

The trigonometric ratios is concerned with the relationship of an angle of a right-angled triangle to ratios of two side lengths.

The basic trigonometric ratios includes;

sine, cosine and tangent.

sin 30 = a/8 {opposite/hypotenuse}

a = 8 × 1/2 {sin 30 = 1/2}

a = 4

cos 30 = b/8 {adjacent/hypotenuse}

b = 8 × √3/2 {cos 30 = √3/2}

b = 4√3

sin 45 = 4√3/d

d = 4√3 × 2/√2 {sin45 = √2/2}

d = 4√6

cos 45 = c/4√6

c = 4√6 × √2/2

c = 2√12

c = 4√3

Therefore, the exact lengths of the missing sides for the right triangle using trigonometric ratio of the respective angles are: a = 4, b = 4√3, c = 4√3, and d = 4√6
