Answer:

a)  See below.

b)  Arithmetic sequence

[tex]\textsf{c)} \quad a_n=10n-7[/tex]

Step-by-step explanation:

From inspection of the given table, t(n) increases by 10 each time n increases by 1.

Therefore:

[tex]\implies a_7=53+10=63[/tex]

[tex]\implies a_8=63+10=73[/tex]

Completed table:

[tex]\begin{array}{|c|c|}\cline{1-2} \vphantom{\dfrac12} n&t(n) \\\cline{1-2} \vphantom{\dfrac12} 4& 33\\\cline{1-2} \vphantom{\dfrac12} 5& 43\\\cline{1-2} \vphantom{\dfrac12} 6&53 \\\cline{1-2} \vphantom{\dfrac12} 7&63\\\cline{1-2} \vphantom{\dfrac12} 8& 73\\\cline{1-2} \end{array}[/tex]

As the given sequence has a constant difference of 10, it is an arithmetic sequence.

[tex]\boxed{\begin{minipage}{8 cm}\underline{General form of an arithmetic sequence}\\\\$a_n=a+(n-1)d$\\\\where:\\\phantom{ww}$\bullet$ $a_n$ is the nth term. \\ \phantom{ww}$\bullet$ $a$ is the first term.\\\phantom{ww}$\bullet$ $d$ is the common difference between terms.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]

The common difference is 10. Therefore:

To find the first term, a, substitute the value of d and one of the terms into the formula:

[tex]\begin{aligned}\implies a_4=a+(4-1)(10)&=33\\a+3(10)&=33\\a+30&=33\\&a=3\end{aligned}[/tex]

Therefore, to write an equation for the given arithmetic sequence, substitute the found values of a and d into the formula:

[tex]\implies a_n=3+(n-1)(10)[/tex]

[tex]\implies a_n=3+10n-10[/tex]

[tex]\implies a_n=10n-7[/tex]

Answer: We need to add 1 7/8 to 5 5/8 to make 7 as an improper fraction. ✅

PLEASEEEE GIVE BRANLIEST

Step-by-step explanation: To add 5 5/8 to a number to make 7 as an improper fraction, we need to convert 5 5/8 to an improper fraction.

To convert a mixed number to an improper fraction, we take the whole number, multiply it by the denominator of the fraction, and add the numerator. So, 5 5/8 becomes (5 x 8) + 5 / 8 = 40 + 5 / 8 = 45/8.

Now, we can add 45/8 and the number that we need to add to make 7 as an improper fraction.

45/8 + x = 7

To find x, we can subtract 45/8 from both sides of the equation:

x = 7 - 45/8

x = 1 7/8

So, we need to add 1 7/8 to 5 5/8 to make 7 as an improper fraction. ✅

Therefore , the solution of the given problem of relative frequency comes out to be 20% of student population is between the ages of 35 and 38.

Answer:

The equation of line is y = -2/3x - 4, option C is correct.

Step-by-step explanation:

The line that cuts through (1, 2) and is perpendicular to (y = 1/3x + 4) has the equation (y = -3x + 5).

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.

On the y-axis, this value c is referred to as the intercept.

Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.

y = 1/3x + 4 is the line that crosses (1,2) and is perpendicular to it.

To ascertain the equation of the line, utilize the procedures below:

Step 1: Two lines that are perpendicular to one another have the following slopes:

mm' = 1

Where the slopes of the lines are m and m'.

Step 2 - The line that is perpendicular to the line (y = 1/3x + 4) has the following slope:

1/3 * m' = -1

m' = -3

Step 3: The equation for a line passing through the points (1, 2) and having a slope of -3 is as follows:

(y - 2) = -(x - 1)

Implicate the equation above:

y = -3x + 5

Therefore, the line that cuts through (1, 2) and is perpendicular to (y = 1/3x + 4) has the equation (y = -3x + 5).

Step-by-step explanation:

The probability of total of 8 is 0.1389, the probability of at most a total of 5 is 0.2778.

A pair of fair dice is tossed.

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur.

The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.

Probability of event to happen

(a)) A total of 8 can be obtained with the following outcomes,

The sample space S contains n(S) = 36 elements when a pair of dice is tossed.

⇒{(2,6),(3,5),(4,4),(5,3),(6,2)} i.e. 5 outcomes.

⇒Required probability = [tex]\frac{5}{36}[/tex] = 0.1389

The probability of a total of 8 is 0.1389.

The length of the isosceles trapezoid height CE is 14 meters.

To find the length of the height CE of the isosceles trapezoid, we can use the Pythagorean theorem.

The isosceles trapezoid CE is the hypotenuse of the right triangle formed by height CE and distance AC. CE is also the height of the trapezoid. Let the length of CE be 'x'

The Pythagorean theorem states that the square of the length of the hypotenuse of a right triangle (CE) is equal to the sum of the squares of the lengths of the other two sides (AC and CE).

x² = AC² + CE²

We know that AC = 14 meters and CE = x.

So x² = 14² + x²

x² = 196 + x²

x² = x² + 196

0 = 196

x = √196 = 14

Therefore, the length of height CE is 14 meters.

The value of the combined function f(g(x)) will be -16x^2+88x-120.

What is a function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and co-domain or range. A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).

There are several types of functions in math. Some important types are:

Injective function or One to one function: When there is mapping for a range for each domain between two sets.

Surjective functions or Onto function: When there is more than one element mapped from domain to range.

Polynomial function: The function which consists of polynomials.

Inverse Functions: The function which can invert another function.

If the town will permit a parking lot at angle J if the measure of angle Ji is greater than 38°, then yes, a parking lot can be erected at angle K.

In Euclidean geometry, an angle is a shape that is made up of two rays, known as the hood's sides, that meeting at a middle point known as the wall's apex. Two rays may combine to form an angle in the planes where they are positioned. When two planes collide, an angle is also created. They are referred to as dihedral angles. An angle in plane geometry is the possible configuration of two photons or lines that share a termination. The origin of the English term "angle" is the Latin word "angulus," which meaning "horn." The vertex is the point where the two rays, sometimes known as two sides of the angle, converge.

In this problem we find a quadratic-like equation of the form a · x²ⁿ + b · xⁿ + c = 0, where a, b, c are real coefficients and whose roots must be found. This can be done by completing the square and clear variable x. First, write the polynomial:

It simply means that the probability of selection.

For example,  at a school board meeting there are 9 parents and 5 teachers. Two teachers and 5 parents are female. If a person at the school board meeting is selected at random, we can use the concept of probability selection to find the probability that the person is a parent or a female.

Now, we are told that a recent survey of 37 million citizens in the United States, 5 million were planning to start a new degree program or continue their education in the next year. Thus, we can say that;

Total number of people in survey = 37 million

Number of people planning to start a new degree program or continue their education in the next year = 5 million

Thus;

P(People starting new program) = 5 million/37 million
