Answer:

[tex]x^{2} - 14 = 50[/tex]

Step-by-step explanation:

Let x = Unknown number

Number squared = [tex]x^{2}[/tex]

Difference between the number squared and 14 is 50:

= [tex]x^{2} - 14 = 50[/tex]

= [tex]x^{2} = 14 + 50[/tex]

= [tex]x^{2} = 64[/tex]

(NOTE: It cannot be [tex]14 - x^{2} = 50[/tex] since:

[tex]x^{2} = 14 - 50[/tex] which would mean [tex]x^{2} = -36[/tex] and a square of a number CANNOT be a negative number)

Taking the square root of both sides to get rid of the square:

the maximum number of data points that fall below the second quantile is 4.

4 data points.

Quantiles divide a set of data into four equal parts, each with an equal number of data points. In this case, 36 data points are divided into 9 quantiles, meaning each quantile contains 4 data points. Therefore, the maximum number of data points that fall below the second quantile is 4.

Quantiles divide a set of data into equal parts, each with an equal number of data points. The number of quantiles is determined by the total number of data points. For example, if there are 36 data points, then it is divided into 9 quantiles, each with 4 data points. The lower the quantile, the lower the value of the data points it contains. Therefore, the maximum number of data points that fall below the second quantile is 4.

Elena spent an amount of $4.10 + p more than Taniy.

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

Let's represent the amount spent by Elena and Taniy as E and T, respectively. We know that:

E = 8.25 + 4p (since Elena bought a watermelon for $8.25 and 4 pounds of cherries for 4p)

T = 4.15 + 3p (since Taniy bought a pineapple for $4.15 and 3 pounds of cherries for 3p)

The expression to represent how much more Elena spent can be represented as:

E - T = (8.25 + 4p) - (4.15 + 3p)

Expanding the right side:

E - T = 8.25 + 4p - 4.15 - 3p

Combining like terms:

E - T = 4.10 + p

So Elena spent $4.10 + p more than Taniy.

The area of shape B is 312.5 cm²

Let us assume that the area of the shape B is m square units.

Here, the dimensions of shape A is 12 cm and the area of the shape A is 200 cm²

The dimensions of shape B is 15 cm and the area of the shape B is m cm²

Since A and B are two similar 2D shapes their dimensions must be in proportion.

So, we get an equation,

⇒ A² / B² = 200 / m

⇒ 12² / 15² = 200 / m

⇒ 144 / 225 = 200 / m

Answer: Let x be the number of shirts that David buys.

The cost of the shirts can be represented by the equation: $15x.

The total amount of money that David has spent can be represented by the equation: $32.25 + $15x.

Since David has a total of $65 to spend, we can write the inequality:

$32.25 + $15x ≤ $65

Solving for x, we get:

$15x ≤ $65 - $32.25 = $32.75

$15x ≤ $32.75

$x ≤ $32.75 / $15 = 2.183333

Since David can only buy a whole number of shirts, the maximum number of shirts that he can buy is 2.

So, the maximum number of shirts David can buy is 2.

An approximate size which does not represent any of the actual dimensions of the unit is nominal value.

The phrase "nominal number" is said to be quite new and rarely used. It seems to have come from the statistical phrase "nominal data," which is reportedly defined as data revealing "...merely declarations of qualitative category of membership," as it is used in school textbooks. The meaning of the word "nominal" in this use is "name."

Nominal numbering is mathematically a one-to-one and onto function from a set of named objects to a set of numbers, which may change (typically growing) over time. It is a function because each named object is assigned a single number; it is one-to-one because different objects are assigned different numbers; and it is onto because every number in the set at a given time has a single named object associated with it.

Answer & Step-by-step explanation:

To multiply these two binomials, we can use the distributive property as follows:

(2x+5)(3x+1) = 2x(3x+1) + 5(3x+1)

Now, we can simplify each term:

2x(3x+1) = 6x^2 + 2x

5(3x+1) = 15x + 5

Putting these back together, we get:

(2x+5)(3x+1) = 6x^2 + 2x + 15x + 5

Simplifying the middle two terms, we get:

(2x+5)(3x+1) = 6x^2 + 17x + 5

Therefore, the expression that is equivalent to (2x+5)(3x+1) is 6x^2 + 17x + 5.

Answer:

x = 2

Step-by-step explanation:

We can start by rewriting the equation as follows:

100 * (1/5)^x / 4 = 4

Next, we'll multiply both sides by 4 to cancel out the division by 4:

400 * (1/5)^x = 16

Finally, we'll divide both sides by 400 * (1/5)^x to isolate (1/5)^x:

1/((1/5)^x) = 16 / 400 = 1/25

Taking the reciprocal of both sides:

(1/5)^x = 25

Taking the power of 5 to both sides:

x = log(25)/log(5) = 2

So x = 2 is the solution to the equation.

The possible values of x % 10, where x is an integer, are integers between 0 and 9, inclusive, i.e. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

The modulo operation (represented by the percent symbol %) returns the remainder of the division of one number by another. For example, when x is divided by 10, the result of x % 10 is the remainder of that division.

Since 10 is a positive integer, when x is divided by 10, the result is always a non-negative integer. Furthermore, since the range of x is all integers, the result of x % 10 will always be less than 10.

Therefore, the possible x % 10 are integers in the range of 0 to 9, including 0 and 9. These are the remainders that can result from dividing x by 10. For example:

7 % 10 = 7

17 % 10 = 7

27 % 10 = 7

In all of these cases, the remainder is 7 when the number is divided by 10.

Answer:

The perimeter of triangle ABC with altitude BD can be found by using the Distance Formula. The coordinates of the vertices are A(-5, 2), B(-3, 5), C(5, 2), and D(-3, 2). The perimeter is then calculated as the sum of the distances between each pair of points: P = AB + BC + CD + DA = 8.24 units. The area can be found using Heron's Formula, which gives an area of 6.00 units.

Step-by-step explanation:

The perimeter of triangle ABC with altitude BD can be found by using the Distance Formula. The coordinates of the vertices are A(-5, 2), B(-3, 5), C(5, 2), and D(-3, 2). Using the Distance Formula, the sides of the triangle can be calculated as follows: AB = √((-3 - (-5))² + (5 - 2)²) = √(8 + 9) = √17; BC = √((5 - (-3))² + (2 - 5)²) = √(8 + 9) = √17; and AC = √((-5 - 5)² + (2 - 2)²) = 0. Therefore, the perimeter of triangle ABC is AB + BC + AC = 17√2 units.

The area of triangle ABC can be found using Heron's Formula, which states that the area of a triangle is equal to the square root of s(s-a)(s-b)(s-c), where s is half of the perimeter and a, b, and c are the lengths of each side. In this case, s is half of 17√2 or 8.5√2 units. Plugging in these values into Heron's Formula yields an area for triangle ABC equal to 8.5√2 * 4 * 3 * 1.5√2 or 36√2 units squared.

Answer:

12 units

Step-by-step explanation:

AB^2 = [(-5) - (-2)]^2 + [(-2) - (-2)]^2 = 9

AB = 3

So similarly, BC = 5 and AC = 4

Hence, the perimeter = AB + BC + AC = 12 units

A frequency distribution for a collection of data is shown in the accompanying table.

The intervals or ranges of the data are displayed in the left column of the table, and the frequency or number of observations within each interval is displayed in the right column.

For instance, the first row demonstrates that 4 observations fall within the range of 10 to 19 while the second row demonstrates that 5 observations fall within the range of 20 to 29.

We only combine the frequencies to determine the total number of observations:

Total observations equal 25 (4 + 5 + 8 + 7 + 1 = 25)

By averaging the bottom and upper interval bounds, we can also determine each interval's midpoint. As an illustration, the first interval's midway (10-19) is as follows:

Midpoint: (14.5) (10 + 19) / 2

This may be done for each interval, and to display the midpoints, we can add a third column to the table.

The cumulative frequency, which is the overall frequency as we progress from the shortest interval to the longest interval, can then be calculated. The cumulative frequency can be displayed in the table by using a fourth column.

The finished table is shown here:

Interval Frequency Midpoint Cumulative Frequency
