The value of c is 20.35 (approx).

What is Pythagorean Theorem?

The Pythagorean Theorem states that the hypotenuse, or side opposite the right angle, of a right triangle, which is represented by the square, is equal to the sum of the squares on the legs of the triangle (or, in popular algebraic notation, a2 + b2 = c2).

Where is the Pythagorean theorem used?

The following are some significant applications of the Pythagorean theorem in daily life: used in architecture and building, used to determine the shortest distance in two-dimensional navigation. used to measure how steep a mountain's or hill's slope is.

Let the other 2 sides of the triangle be named a and b

Given:- a = 15.5ft

            b = 13.2ft

According to the Pythagorean Theorem, We know that

[tex]a^{2}+b^{2}=c^{2}[/tex]

By substituting the values of a and b we get

[tex]15.5^{2}+13.2^{2}=c^{2}[/tex]

[tex]c^{2}= 414.5\\c=\sqrt{414.5}\\ c=20.35[/tex]

c is the hypotenuse of the triangle.

Hence the value of c is 20.35

Noah went into a movie theater and bought 9 drinks and 4 candies, costing a total of $60. Nachelle went into the same movie theater and bought 10 drinks and 2 candies, costing a total of $57.50. Determine the price of each drink and the price of each candy.

Answers

Answer:

See below.

Step-by-step explanation:

Let the price of drinks be x and the price of candies be y.

Condition # 1:

9x + 4y = 60 --------------------(1)

Condition # 2:

10x + 2y = 57.50 --------------(2)

Multiply Eq. (2) by 2

2(10x + 2y) = 57.50*2

20x + 4y = 115 --------------(3)

Subtract Eq. (3) from (1)

9x + 4y - 20x - 4y = 60 - 115

9x - 20x = -55

-11x = -55

11x = 55

Divide both sides by 11

x = 55/11

x = $5

Put x = 5 in Eq. (1)

9(5) + 4y = 60

45 + 4y = 60

Subtract 45 to both sides

4y = 60 - 45

4y = 15

Divide both sides by 4

y = 15/4

y = $3.75

So, the cost of one drink is $5 and the cost of one candy is $3.75.

Given: ABCD trapeziod, AB=DC, BK - altitude, AB=8, AK=4
Find: m

Answers

The value of angle A and B are 60° and 120° respectively.

How to calculate the angles?

It is important to note that in isosceles trapezoid, the angles adjacent to the bases are congruent.

Therefore A = D

B = C

When in the right angle, the hypothenuse is twice the leg, the angle opposite it will be:

ABK = 30°

Also, KBC = 90°

Therefore, B = 30° + 90° = 120°

Given that the coefficient of x³ is twice the coefficient of x² in the binomial expansion of f(x)

(a) It is proved that n = 6k + 2

(b)k = 2 and n=14

(c) After expansion, the equation is
   1 + 14x + 91/4x^2 + 1001/2x^3 + 1001/16x^4 + 1001/16x^5

What is the binomial theorem?

The algebraic expansion of a binomial's powers is described by the binomial theorem (also known as binomial expansion) in elementary algebra.
The theorem states that the polynomial (x + y)n can be expanded into a sum including terms of the form axbyc, where the exponents b and c are nonnegative integers and b + c = n, and the coefficient an of each term is a particular positive integer dependent on n and b.

Solution Explained:


f(x)= (1+x/k)^n

Given that the coefficient of x^3 is twice the coefficient of x^2 in the binomial expansion of f(x)

a)

Coeff of x^3 = 1/6[n(n-1)(n-2)/k3]

Coeff of x^2 = 1/2[n(n-1)/k2]

1/6[n(n-1)(n-2)/k3] = 2* 1/2[n(n-1)/k2]

Canceling on both sides gives:

(n-2)/(6k) = 1

n = 6k+2        Hence proved

Given also that the coefficients of x^4 and x^5 are equal and non-zero,

b)

Coeff x^4 = 1/24 [n(n-1)(n-2)(n-3)/k4

Coeff x^5 = 1/120 [n(n-1)(n-2)(n-3)(n-4)/k5

1/120 [n(n-1)(n-2)(n-3)(n-4)/k5 = 1/24 [n(n-1)(n-2)(n-3)/k4

Canceling gives:

(n-4)/(120k) = 1/24

n = 5k+4

From previous:

n = 6k+2 = 5k+4

k = 2

n=14

Using these values of k and n,

c)

Give each coefficient as an exact fraction in its lowest terms
1 + 14x + 91/4x^2 + 1001/2x^3 + 1001/16x^4 + 1001/16x^5

Answers

The joint relative frequency is 23%. So option (1) is correct.

Joint relative frequency is defined as the ratio of a frequency that is not in the total row or column to the total number of values or observations. The marginal frequency in a two-way frequency table is the entry in the "total" for the column and the "total" for the row.

Given data:

                         Traditional     Online       Row totals

Computer:             28                62               90

Mobile device:       46                64              110

Column totals:       74               126             200

The joint relative frequency can be found by the formula:

= (Number of students using a mobile device in traditional class / Total Number of students) x 100%

Number of students using mobile devices in traditional class = 46

Total number of students = 200

= (46 / 200) x 100%

= 0.23 x 100%

= 23 %

Hudson goes to a store an buys an item that costs x dollars. He has a coupon for 20%

of a that represents the total amount that Hudson paid at the register.

Answers

If Hudson having a discount coupon of 20% off, wants to buy an item having a printed price of "x" dollars, and a 5% tax is added to the discounted price in the end, then the expression that can represent the final amount Hudson paid for the item will be [(4x/5) + (x/25)].

As per the question statement,  Hudson goes to a store an buy an item that costs "x" dollars, with the intention of using his 20% flat discount coupon, and then, a 5% tax is added to the final discounted price.

We are required to determine an expression that can represent the final amount Hudson paid for the item as per the above case.

Since Hudson gets a discount of 20% over the cost price of his desired item, the discounted cost price of the item becomes, [x - {(20/100) * x}]

                                                                                 = [x - {(1/5) * x}]

                                                                                 = [x - (x/5)]

                                                                                 = (4x/5).

And then, a 5% tax is added to the final discounted price, which takes the final amount to [(4x/5) + {(5/100) * (4x/5)]

                      = [(4x/5) + {(1/20) * (4x/5)]

                      = [(4x/5) + (x/25)]

                      = (21x/25)

A binomial probability is employed to answer this question since the chances that one appeal will be permitted is independent of the possibility that any other appeals will be granted.

The probability of precisely x successes per n repeated trials is known as a binomial probability, and X has only two possible outcomes.

P(X = x) = Cn,ₓ.pˣ(1 - p)ⁿ⁻ˣ   ...eq 1

Where  Cn,ₓ represents the number of distinct combinations of x items drawn from a group of n elements, as determined by the formula below.

Cn,ₓ = n!/x!(n - x)!

Where p is the likelihood that anything will happen.

10 appeals are necessary; n = 10.

Because 40% of appeals are successful; p = 0.4.

For the probability of getting at least two heads.

P(X ≥ 2) = 1 - P(X < 1)

P(X < 2) = P(X = 0) + P(X = 1)

Put the values in eq 1 and get the values for X.

P(X < 2) = 0.006 + 0.0403  = 0.0463

Now,

P(X ≥ 2) = 1 -  0.0463

P(X ≥ 2) = 0.9537

Thus, the probability that of getting more than two heads is 0.9537.

Monthly charge £16
150 free minutes then 13p per minute
150 free texts then 15p per text
during one month,Jo makes 170 calls and sends 182 texts
work out the total charge for the month

Answers

The total charge for the month is £625.36.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given:

Fixed monthly plan - 616

free minutes - 150

Used minutes - 170

Free text - 150

Used text - 182

Charging amount over the free limit - 18p

Number of minutes over the limit -  170 - 150 = 20

Number of text over the limit - 182 - 150 = 32

So the extra amount that will be added to the monthly charge would be -

(20 x 0.18) +(32 x 0.18)

The total charge of the month would be -

C= 616+(20*0.18) +(32*0.18)

C= 616+3.60+5.76

C= 625.36

Therefore, the total charge for the month is £625.36.

The correct question is given below,

Here are the monthly charges for Jo's mobile phone

Monthly charge 616

150 free minutes, then 18p per minute

In the figure shown, line AB is parallel to line CD.

Part A: What is the measure of angle x? Show your work. (5 points)

Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)

AB and CD are parallel lines, and PQ and PR are transversals which intersect AB at P and CD at Q and R. Angle APQ is labeled as 64 degrees, angle QPR is equal to x, angle PRD is equal to 110 degrees.

Answers

A) The value of the measure of angle x is; x = 55 degrees.

B) The way we got x is that the Internal angle between 2 parallel lines are equal and also that the three angles APO, x and BPR form a straight line and they sum up to 180 degrees.

What is the measure of the missing angles?

A) From the given image attached, we see that the angle RPB can be calculated as;

m∠RPB = 180 - 120 = 60 degrees.

This is because sum of angles on a straight line sums up to 180 degrees.

Now, by definition of alternate angles, we can say that angle BPR is equal to 60 degrees.

Thus, the value of angle x is;

x =  180 - 60 - 65

x = 55 degrees.

B) From the given diagram, we can say that;

m ∠RPB + m < PRD = 180 degrees

This is because Internal angle between 2 parallel lines are equal.

Secondly the three angles APO, x and BPR form a straight line and they sum up to 180 degrees.
