Write the following in algebraic language. x is 0.28 of y.

She must have a score greater than the average of 75 on her final exam.

Arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.

Let the required score be x

Mean = 79 + 69 + 61 + 91 + x/5

⇒ 79 + 69 + 61 + 91 + x/5 > 75

⇒ 300 + x/5 > 75

⇒ 300 + x > 375

⇒ x > 375 - 300

⇒ x > 75

This implies that she needed a score on her final exams that were higher than the average of 75.

The percentage of fraction 3/7 is 42.8571%.

Percentage, a relative value indicating hundredth parts of any quantity. One percent  is a hundredth part; thus, 100 percent represents the entirety and 200 percent specifies twice the given quantity.

All of something is 100 percent, half of it is fifty percent, none of something is zero percent. To determine a percentage, you divide the portion of the whole by the whole itself and multiply by 100.

Given fraction:

3/7

To convert the fraction into percentage we have multiply 100

3/7*100

=300/7

= 42.8571%

Hence, the percentage of fraction 3/7 is 42.8571%.

The required transformation of graphs are represented and attached below.

Given:

(a) function f(x) = |x| transformed to g(x) = 3 |x ₋ 1 | ₊ 3

To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.

Parent Function : f(x) = |x|

Horizontal Shift: Right 1 Units

Vertical Shift: Up 3 Units

Reflection about the x-axis: None

Vertical Stretch: Stretched

(b) If there is a horizontal or vertical shift, reflection around the x-axis or y-axis, or vertical stretch, the function has undergone transformation. To identify the transformation, compare the function to the parent function.

Parent Function : f(x) = |x|

Horizontal Shift: Right 1 Units

Vertical Shift: Up 6 Units

Reflection about the x-axis: None

Vertical Stretch: Stretched

Let the equation be ax² + bx + c = 0. Then the roots of the equation will be

[tex]\rm x = \dfrac{-b \pm \sqrt{b^2 - 4 a c }}{2a}[/tex]

The quadratic equation is given below.

(4/2)x + 1 + (1/4)x² - 1 = 1

Simplify the equation, then we have

(4/2)x + 1 + (1/4)x² - 1 = 1

2x + 1 + (1/4)x² = 0

x² + 8x + 4 = 0

Then the solution of the equation is given as,

[tex]\rm x = \dfrac{-8 \pm \sqrt{8^2 - 4 \times 1\times 4 }}{2 \times 1}\\[/tex]

Answer: Ratio of men to women is 7:  9

Step-by-step explanation:

Total: 32

Women: 18

Men: 32 - 18 = 14

Ratio of Men to Women would be 14 : 18. That simplified is 7 : 9

Answer:1.7

Step-by-step explanation:

divide 32/18=1.7

Using the normal distribution, it is found that the z-score of the height of a women 5.5 feet tall is 0.51.

The problem asks for the z-score of the height of a women 5.5 feet tall.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Considering that each feet has 12 inches, the parameters are given as follows:

[tex]X = 5.5 \times 12 = 66, \mu = 64.1, \sigma = 3.7[/tex]

Hence the z-score is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (66 - 64.1)/3.7

Z = 0.51.

The z-score of the height of a women 5.5 feet tall is 0.51.

Answer: 60 years

Step-by-step explanation:

ur answer is 60 because it's the same as 3+3 its 6 but it's

kind of the opposite way

0.48

Step-by-step explanation:

To find the gradient when given points, label one of the x points as X2 and the other x1 ( it could be anyone of them: 3 could be X2 and 6 x1 or vise versa) and do the same with the y points, doesn't matter which one is y2 or y1.

But bare in mind, if you used the first coordinate x as x1 you must used the y coordinate as the y1. you must use the same order. so if you used X2 for second coordinate use y2 for the y point of the second coordinate.

Now set up the formula: x2-x1/y2 -y1

=( 3-6)/((-1)-5.2/

=0.48

90 in²

Area is the amount of space a 2-D shape occupies.

Area Formula

As stated above, the area of a triangle is [tex]\frac{1}{2}bh[/tex]. When solving for area, it doesn't actually matter which side is the base. You just have to remember to take the height perpendicular to the base you use. Since this is a right triangle, the height is the same as one of the legs. For the purpose of this question, I will use 12 as the base and 15 as the height. Because the 12 and 15 sides are perpendicular to each other, we can plug them into the formula for b and h.

Solving For A

Now we can just plug 12 and 15 in and solve.

The area of the triangle is 90 in².

The value of x and y that allows these two triangles to be congruent is

(-12, 11)

The congruence of two or more triangles is determined by the measurements of their sides and angles. The three sides of a triangle determine its size, and the three angles determine its shape.

Two triangles are said to be congruent if the pairs of their corresponding sides and angles are equal. They are the same size and shape. Triangles have numerous congruence conditions.

Here we will use translation to find out units of displacements

If the triangle is congruent then vertices are of same shape too which means coordinate of first triangle will give us coordinate of second triangle

The coordinates of 1st vertices of traingle1 = (5, 4), x = 5, y = 4

The coordinates of 1st vertices of traingle2 = (1, 6), x = 1, y = 6

By subtracting,

translation x = 5 - 1 = 4

translation y = 4 - 6 = -2

Thus the vertices of other triangles are translated 4 units left and 2 units up. Same goes for second vertices

-4 - 4 = 8

6 + 2 = 8

And the same will go for the last vertices (-8, 9) that is

-8 - 4 = -12

9 + 2 = 11

The value of x and y that allow these two triangles to be congruent is (-12, 11)

Collecting pennies can either be a dependent or an independent events based on the scenario.

Events classified as independent do not depend on other events for their occurrence. For instance, if we toss a coin in the air and it lands on head, we can toss it again and this time it will land on tail.

A coin toss is an illustration of an autonomous occurrence. With each toss of the coin, there is an equal probability (0.5) of either heads or tails occurring, presuming that the coin is fair and can only land on heads or tails. It doesn't matter if the coin came up heads on the prior toss.

The conjecture about the backpack sales in June is that less than 8,000 backpacks were sold

From the graph, the number of backpack sales in June is not represented on the graph

The last month represented on the graph is May

On the vertical axis of the graph, the number of backpack sales that corresponds to the month of May is between 8,000 and 8,5000

By looking at the trend,

This means that the number of backpack sales in the month of June is less than the number of backpack sales in the month of May

The conjecture about backpack sales is that June sales will be less than 8,000 units.

A conjecture is a mathematical statement without proof. Instead, conjectures survive on some existing patterns.

The existing patterns show that backpack sales peaked in November but deteriorated or decreased steadily every month.

For instance, in November, the backpack sales were 11,000 units but 10,250 in January. It reduced to 8,750 in March.

However, following the end of the Easter holidays, backpack sales may increase from May. But this prediction does not agree with the trend.

Thus, the conjecture about backpack sales is that June sales will be less than 8,000 units.

Perpendicular lines from angles that measure (90) degrees

Answer: Division

Step-by-step explanation: It's simple. 1/10 = divided by 10. So, all you have to do is divide 10 by 300 and get your answer

Hey there!

1/10 of 300 = 30

1/10 * 300 = 30

1/10 * 300/1 = 30

1(300)/10(1) = 30

300/10 = 30

300 ÷ 10 / 10 ÷ 10 = 30

30 / 1 = 30

30 ÷ 1 = 30

30 = 30

Therefore, your could say you: Simplified your given equation (1/10 * 300) like how I did above and you received the answer (30) & the statement is very much true

Like terms are the terms that contain same variables raised to the same power, the coefficients need not be same. For example, 7x and 2x are like terms because both terms contain same variable "x".

We can actually deduce here that considering the conditional statement and scenario, the conditional statement is false.

Conditional statement is actually known to be an if-then statement. It is usually used to show and emphasizes the relationship that exists between two ideas. This means that one idea comes as a result of the other.

Conditional statements actually helps one to make proper deductions in a clear and rigorous way.
