The number of mangoes she picked is 2.

Number is the concept of a mathematical object used to count, measure, and label. It is an abstract concept, though most familiar in the form of numerals such as "3" or "10". Numbers allow us to compare and manipulate amounts, sequences, shapes, and patterns. They also allow us to create models and make predictions. As a result, they are essential tools in a variety of disciplines, from mathematics and physics to engineering and economics.

Let x be the number of mangoes in each group on Monday. The expression representing the number of mangoes in each group is x + 4/2 = x + 2.

b) Let y be the number of mangoes in each group on Tuesday. The expression representing the number of mangoes in each group is 2y + 2/3 = 2y + 2/3.

c) Let z be the number of mangoes left after subtracting the number of mangoes in each group on Tuesday from the number of mangoes in each group on Monday. The equation representing this information is x + 2 - (2y + 2/3) = z.

d) Substituting the expression for x and y in the equation, we get: (2y + 2/3) + 2 - (2y + 2/3) = z.

Solving the equation, we get z = 2.

Hence, the number of mangoes she picked is 2.

Answer:

If the question is x^2 + x - 20 = 0,

x = -4,5

However, if the question is x^2 - x - 20 = 0,

x = 4, -5

Step-by-step explanation:

WARNING: Your question is incorrect and so, I have tweaked it to make it correct

Completing the square of (x^2 + x - 20):

(x^2 - x) - 20

= (x^2 - x + (1/2)^2 - (1/2)^2) - 20

= (x^2 - x + (1/4))^2 - 1/4 - 20

= (x-1/2)^2 - 81/4

Hence,

(x-1/2)^2 - 81/4 = 0

(x-1/2)^2 = 81/4

x-1/2 = + or - 9/2

x = 9/2 + 1/2 (OR) x = -9/2 + 1/2

x = 5 (OR) x = -4

Hence,

x = -4,5 (CONSIDERING THE QUESTION IS x^2 + x - 20 = 0)

An inequality in mathematics is a comparison between two values or expressions that specifies whether they are equal, greater than, or less than one another. "!=" (greater than or equal to), and "=" (less than or equal to) are used to represent inequality (not equal to). For instance, the inequality "x > 2" denotes that the value of x is more than 2, while the inequality "5 7" denotes that 5 is less than 7. Variables may be utilized in inequalities, which can be used to indicate a variety of values or circumstances that satisfy the inequality.

The arc angle QPS is 258 degrees.

A cyclic quadrilateral is a four sided shape(quadrilateral) that can be inscribed into a circle. The sum of angles in a cyclic quadrilateral is 360 degrees.

The opposite angles of a cyclic quadrilateral have a total of. 180 ° . In other words, the opposite angles of a cyclic quadrilateral is supplementary angles.

Therefore,

m∠P = 4x - 1

m∠R = 12x - 27

Hence,

4x - 1 + 12x - 27 = 180

16x - 28 = 180

16x = 180 + 28

16x = 208

x = 208 / 16

x = 13

m∠R = 12(13) - 27

m∠R = 156 - 27

m∠R = 129 degrees

Therefore,

m∠R = 1 / 2 (QPS)

The required possible dimensions of the​ rug are 11   by  [tex]\frac{r^2 - 8r - 33}{11}[/tex].

The area of the rectangular rug is given by the trinomial:

[tex]$r^2 - 8r - 33$[/tex]

To find the possible dimensions of the rug, we need to factor this trinomial. We can do this by finding two numbers that multiply to -33 and add up to -8. These numbers are -11 and 3:

[tex]$r^2 - 8r - 33 = (r - 11)(r + 3)$[/tex]

Therefore, the possible dimensions of the rug are:

[tex]$r - 11 = 0$[/tex] or [tex]$r + 3 = 0$[/tex]

[tex]$r = 11$[/tex]or $[tex]$r = -3$[/tex]

Since the dimensions of the rug cannot be negative, we can only take the positive value of r, which is r = 11.

Therefore, the possible dimensions of the rug are:

The value of the inverse function of f(x), that is, f⁻¹(33) is 2.

A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function. In general, switching the coordinates x and y is how an inverse is calculated. Although not strictly a function, this freshly constructed inverse is a relation.

To guarantee that the original function's inverse will likewise be a function, the original function must be a one-to-one function. Only when every second element matches the first value is a function deemed to be a one-to-one function.

Given that,

f(x)=4x³+1

Also, f⁻¹(33).

Thus, using the input and output corresponding values we have:

f(x) = 4x³ + 1 = 33

x³ = 8

Taking the cube root of both sides, we get:

In response to the query, we can state that As a result, the cubic equation factored form is: f(x) = (x+3)(x+1)(x-2) (x-2)

An equation is a mathematical statement that proves the equality of two expressions connected by an equal sign '='. For instance, 2x – 5 = 13. Expressions include 2x-5 and 13. '=' is the character that links the two expressions. A mathematical formula that has two algebraic expressions on either side of an equal sign (=) is known as an equation. It depicts the equivalency relationship between the left and right formulas. L.H.S. = R.H.S. (left side = right side) in any formula.

A cubic polynomial's graph is the one that is presented. We must determine the polynomial's x-intercepts or roots in order to determine its factored form.

The graph reveals the polynomial's three real roots, which are -3, -1, and 2.

As a result, the polynomial's factored form is:

f(x) = a(x+3)(x+1) (x-2)

where an is a constant that establishes the polynomial's leading coefficient. Using the graph's point (0,-6) as a reference, we may determine the value of a:

Answer:-225

Step-by-step explanation:The arithmetic series is given by:

a1 = -1, d=-2, n = 15

where a1 is the first term, d is the common difference, and n is the number of terms.

To evaluate this series, we can use the formula for the sum of an arithmetic series:

Sn = n/2 * [2a1 + (n-1)d]

where Sn is the sum of the first n terms.

Substituting the given values, we get:

S15 = 15/2 * [2(-1) + (15-1)(-2)]

= 15/2 * [-2 - 28]

= 15/2 * (-30)

Simplifying this expression, we get:

l - 2

Therefore, the expression that best represents the final length of the skirt is:

O2 - s

Answer:  Large box weight 40 pounds, and small box weight 30 pounds.

Step-by-step explanation:

Let L be the weight of a large box, and S be the weight of a small box.

L + S = 70

50L + 60S = 3800

We change the first equation into the form of L, and we get:

L = 70 - S

And we plugin L = 70 - S into the second equation.

  50(70 - S) + 60S = 3800

3500 - 50S + 60S = 3800

          3500 + 10S = 3800

         -3500             -3500

                       10S = 300

                          S = 30

 L + S = 70

L + 30 = 70

  - 30     - 30

       L = 40

d. The probability that a randomly selected watermelon will weigh more than 5.1 kg is 0.7967.

e. The probability that a randomly selected seedless watermelon will weigh between 5.3 and 6 kg is 0.2454.

f. The 85th percentile for the weight of seedless watermelons is 7.2437 kg.

Step-by-step explanation:

a. X ~ N(6.1, 1.2^2)

b. The median of a normal distribution is equal to the mean, so the median seedless watermelon weight is 6.1 kg.

c. The Z-score for a seedless watermelon weighing 7 kg can be calculated as:

Z = (7 - 6.1) / 1.2 = 0.75

Therefore, the Z-score is 0.75.

d. To find the probability that a randomly selected watermelon will weigh more than 5.1 kg, we need to standardize the value using the formula:

Z = (X - μ) / σ

where X is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

Z = (5.1 - 6.1) / 1.2 = -0.8333

Using a standard normal distribution table or a calculator, we can find the probability that Z is greater than -0.8333 to be 0.7967.

Therefore, the probability that a randomly selected watermelon will weigh more than 5.1 kg is 0.7967.

e. To find the probability that a randomly selected seedless watermelon will weigh between 5.3 and 6 kg, we need to standardize the values and find the area under the normal curve between the two Z-scores. The Z-scores for 5.3 kg and 6 kg are:

Z1 = (5.3 - 6.1) / 1.2 = -0.6667

Z2 = (6 - 6.1) / 1.2 = -0.0833

Using a standard normal distribution table or a calculator, we can find the probability that Z is between -0.6667 and -0.0833 to be 0.2454.

Therefore, the probability that a randomly selected seedless watermelon will weigh between 5.3 and 6 kg is 0.2454.

f. The 85th percentile for the weight of seedless watermelons can be found by finding the Z-score that corresponds to the 85th percentile of a standard normal distribution. Using a standard normal distribution table or a calculator, we can find the Z-score to be 1.0364.

To find the corresponding weight, we can use the formula:

Z = (X - μ) / σ

1.0364 = (X - 6.1) / 1.2

X = 7.2437

Therefore, the 85th percentile for the weight of seedless watermelons is 7.2437 kg.

f) 7.3435 kg (using excel)    or      7.348 kg (using normal tables)

Step-by-step explanation:

a) normal distribution just need to be define we his mean and his standard deviation. You just need a sample higher than 30 or to be specified the population is normally distributed
X≈N(μ,σ)= N(6.1,1.2)

b) The median and mean are not necessarily the same, for a normal distribution, which is a symmetric distribution, those values are just the same


c) The equation for Z score is given by:

[tex]z=\frac{x-u}{\sigma}[/tex]

Replacing values:

[tex]Z=\frac{7-6.1}{1.2} =0.75[/tex]

d) first find the Zvalue for 5.1

[tex]Z=\frac{5.1-6.1}{1.2} =-0.83[/tex]

Now, find the probability from  Normal  Distribution table
P(Z>0.83) = 0.7977

e)

first find the Zvalue fo5.3 and 6

[tex]Z=\frac{5.3-6.1}{1.2} =-0.67[/tex]


[tex]Z=\frac{6-6.1}{1.2} =-0.08[/tex]

Now find probabilities from  Normal Distribution  table . Notice you need to subtract   P(Z>0.08)-P(Z>0.67) if you use a positive table.

P(-0.67<z<-0.08) = 0.2143


f) Find the Z score from a   Normal  Distribution table that give you an area of 0.8500 (or the closest value), im using excel for this one since the answer from tables have only TWO decimals and can be problematic if you need more decimal places.

this gives a Z of 1.036433389

now use the Zscore equation but solve for X

[tex]z\sigma+u=x[/tex]

x = 1.036433389(1.2)+6.1 = 7.3437   (Using excel)

If i use a table, the closes is 1.04 (0.8508 which is not exactly 0.85)

In a linear equation,The equation to represent the situation is y = 15 + 30x.

The number of hours Sophia used for the guitar training after paying 75 dollars is 2 hours.

What in mathematics is a linear equation?

An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation. The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times.

Sophia's mother pays the instructor $75 for the guitar lessons.

The equation that can be used to represent the given situation is as follows:

let

x = number of hours used for the training

y = total cost

Therefore,

y = 15 + 30x

Now, Sophia's mother spent 75 dollars for her daughters training. Let's find the hours Sophia used.

Therefore,

75 = 15 + 30x

75 - 15 = 30x

60 = 30x

divide both sides by 30

x = 60 / 30

x= 2

Therefore, she used 2 hours for the training.

The equation for the hyperbola is [tex]y^{2} -4x^{2} =144[/tex]

A hyperbola is a type of conic section, formed by the intersection of a plane with two cones that have a common vertex. It consists of two separate curves that are mirror images of each other, each of which has two branches that extend to infinity.

By Given figure,

C = (0, 0)

V (0, ±6)

b = 6

equation of asymptotes;  [tex]y=[/tex] ±[tex]\frac{a}{b}x[/tex]

then, y = ± [tex]\frac{a}{6} * x[/tex]

given the asymptotes, y = ±2x

by comparing we get, a/6 = 2

a = 12

We know the equation of hyperbola,   [tex]\frac{y^{2} }{a^{2} } -\frac{x^{2} }{b^{2} } =1[/tex]

putting the values of a and b,     [tex]\frac{y^{2} }{12^{2} } -\frac{x^{2} }{6^{2} } =1[/tex]

[tex]\frac{y^{2} }{144} } -\frac{x^{2} }{36} } =1[/tex]

After Simplification, [tex]y^{2} -4x^{2} =144[/tex]

Therefore, the equation for the hyperbola is [tex]y^{2} -4x^{2} =144[/tex]

The vertices of the image are given as follows:

X'(16.5, -9), Y'(13.5,-4.5) and Z'(4.5,-1.5).

The original vertices of the triangle are given as follows:

X(6, -2), Y(4,1) and Z(-2,3).

The vertices of the image are obtained applying the transformations in the context of the problem.

The first transformation is T(5,-4), which is a translation, meaning that 5 is added to the x-coordinate of each vertex, while 4 is subtracted from the y-coordinate of each vertex, hence:

X'(11, -6), Y'(9,-3) and Z'(3,-1).

The final transformation is the dilation with a scale factor of 1.5, meaning that each coordinate of each vertex is multiplied by 1.5, hence:

X'(16.5, -9), Y'(13.5,-4.5) and Z'(4.5,-1.5).

The amount of money Leticia has after x time periods can be calculated using the formula:

f(x) = P(1 + r)^x

where P is the principal (initial amount invested), r is the annual interest rate (expressed as a decimal), and x is the number of time periods.

Substituting the given values, we get:

f(x) = 200(1 + 0.05)^x

Simplifying this expression, we get:

f(x) = 200(1.05)^x

Therefore, the exponential function that best represents this situation is:

f(x) = 200(1.05)^x

The value of x that maximizes the area of the figure is 1.5 inches, and the maximum area is 3.375 square inches.

A rectangle is a two-dimensional form that has four full sides and four right angles. Because the opposing sides are parallel and congruent, it is a unique kind of parallelogram.

To find the maximum area of the figure, we need to determine the value of x that will maximize the area.

The area of the figure can be calculated as:

A = (1.5x)(x) + (1/2)(1.5x)(6-2x)

Simplifying the expression:

[tex]A = 1.5x^2 + 4.5x - 3x^2[/tex]

[tex]A = -1.5x^2 + 4.5x[/tex]

To find the value of x that maximizes the area, we need to take the derivative of A with respect to x and set it equal to zero:

dA/dx = -3x + 4.5 = 0

Solving for x:

3x = 4.5

x = 1.5 inches

Now that we know x=1.5 inches maximizes the area, we can substitute it back into the area equation to find the maximum area:

[tex]A = -1.5(1.5)^2 + 4.5(1.5)[/tex]

A = 3.375 square inches

Therefore, the value of x that maximizes the area of the figure is 1.5 inches and the maximum area is 3.375 square inches.
