After answering the question provided, we can predict that the result will be as by equation As a result, the correct response is: Minimum: 41.64; Maximum: 62.76.

A mathematical equation is a process that links two statements and indicates equality using the equals sign (=). A mathematical statement that proves the equality of two mathematical expressions is known as an equation in algebra. For instance, the equal sign separates the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula may be used to understand the link between the two sentences that are written on opposite sides of a letter. Frequently, the logo and the particular software are identical. like in 2x - 4 = 2, for example.

A binomial distribution with the specified values of n and p has a mean of = np and a standard deviation of = sqrt(np(1-p)).

Inputting n = 261 and p = 1/5 results in:

μ = np = 261 × 1/5 = 52.2

5.28 is equal to sqrt(np(1-p)) = sqrt(261 1/5 4/5)

Calculating the minimal typical value of 2 is as follows:

μ − 2σ = 52.2 − 2 × 5.28 ≈ 41.64

The calculation for the maximum typical value + 2 is as follows:

μ + 2σ = 52.2 + 2 × 5.28 ≈ 62.76

These values are rounded to the nearest hundredth, giving us:

The range is 41.64 to 62.76.

As a result, the correct response is: Minimum: 41.64; Maximum: 62.76.

The mistake Lori made when multiplying is that she didn't regroup the 2 in the tens column, which is correct option(A).

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Lori solved this multiplication problem.

29 × 31 = 699

The mistake Lori made when multiplying is that she didn't

We first construct the extended multiplication.

The result of multiplying 1 × 9 is 9.

The result of multiplying 1 × 2 is 2

After that, we multiply 3 × 9 to get 27. Since 27 is a two-digit number, we must carry the first digit, 2, to the following column.

Then we carry the digit of 2, which is 8, and multiply 3 × 2, which results in 6.

Finally, we get 899 by adding 870 and 29.

Hence, the mistake Lori made when multiplying is that she didn't regroup the 2 in the tens column.

The least value, first quartile, median, third quartile, and greatest value of the data are 4, 5, 8, 9.75 and 15 respectively.

The first step is to arrange the number in ascending order: 4, 5, 5, 6, 8, 8, 9, 10, 12, 15

The median is the number in the center of the data set. The number is 8.

First quartile = 1/4 x (n + 1) = 2.75 number : 5

Third quartile = 3/4 x (n + 1) = 8.75 = 9.75

Rational numbers are the type of numbers that can be written in fraction forms (1/b where a and b are integers and b ≠ 0). Rational numbers also include decimals that are repetitive (0.313131313131) and decimals that end (0.25).

The opposite are irrational numbers that cannot be written in fraction forms and that include decimals that do not end or repeat (0.249654296432926....).

It is good to know a fraction with denomination equal to zero will give an undefined value.

Answer:

(2, -3), (3, -3)

Step-by-step explanation:

y = x^2 - 5x + 3

y = -3

x^2 - 5x + 3 = -3

x^2 - 5x + 6 = 0

(x - 3)(x - 2) = 0

x - 3 = 0 or x - 2 = 0

x = 3 or x = 2

We are given y = -3.

Answer: (2, -3), (3, -3)

Answer:

(2, -3) , (3, -3)

Step-by-step explanation:

One is asked to find what values of the parameter (x) will yield the result (f(x)=-3) if the function (f(x)) is the following,

[tex]f(x)=x^2-5x+3[/tex]

Set this equation up, and solve to find the value of (x) that satisfies this requirement:

[tex]f(x)=x^2-5x+3=-3[/tex]

Inverse operations,

[tex]x^2-5x+6=0[/tex]

Factor, rewrite the quadratic equation as the product of two linear equations,

[tex](x-2)(x-3)=0[/tex]

Therefore the solutions are the following, the (x-coordinate) represents the input, and the (y-coordinate) represents the output.

Answer:

[tex]Mid(A) = 73[/tex]

[tex]IQR(B) = 8[/tex]

The difference of the medians of class A and class B is between  the interquartile range of either data set.

Step-by-step explanation:

Given

The attached box plots

To answer this, see attached image for how to read a box plot

With reference to the attached image of how to read the box plot;

Solving (a): The median of class A

[tex]Mid(A) = 73[/tex]

Solving (b): IQR of class B

IQR is calculated as:

[tex]IQR =Q_3 - Q_1[/tex]

From the box plot of class B, we have:

[tex]Q_3 = 87[/tex]

[tex]Q_1 = 79[/tex]

So, we have:

[tex]IQR(B) = 87 - 79[/tex]

[tex]IQR(B) = 8[/tex]

Solving (c):

[tex]Mid(A) = 73[/tex]

[tex]Mid(B) = 82[/tex]

[tex]IQR(B) = 8[/tex]

IQR of class A is calculated as:

[tex]IQR =Q_3 - Q_1[/tex]

From the box plot of class A, we have:

[tex]Q_3 = 76[/tex]

[tex]Q_1 = 68[/tex]

So, we have:

[tex]IQR(A) = 78 - 68[/tex]

[tex]IQR(A) = 10[/tex]

The difference (d) between the medians is:

[tex]d =Mid(B) - Mid(A)[/tex]

[tex]d = 82 - 73[/tex]

[tex]d = 9[/tex]

From [tex]smallest[/tex] to [tex]largest[/tex], we have: 8, 9, 10

i.e. IQR(B), d, IQR(A)

Answer:

a=12

Step-by-step explanation:

We must use SOH, CAH, TOA

SOH= Sin0=opp/hyp

CAH=Cos0=adj/hyp

TOA= Tan0=opp/adj

Since we have opposite and hypotenuse we use Sin ratio, in this case,

sin30°= [tex]\frac{a}{24}[/tex]

[tex]\frac{1}{2}[/tex]=[tex]\frac{a}{24}[/tex] we cross multiply

[tex]\frac{2a}{2}[/tex]=[tex]\frac{24}{2}[/tex]divide both sides by 2 to get a by itself

a=12

Answer:

a = 12

Step-by-step explanation:

To find a, we will use the trigonometric ratio of Sin, since the opposite side of the angle given needs to be found out and the hypotenuse is given;

Sin(30) = [tex]\frac{a}{24}[/tex]

Sin(30) * 24 = a

12 = a
