By evaluating the linear equation, we will see that Mr. Dyson will buy 20 packs of nickel strings.

We know that the linear equation:

6x + 4.5*y = 90

Represents the given situation, where the variable x is the number of bronze strings and y is the number of nickel strings.

We want to find the number of packs of nickel strings that he will buy if he does not buy any bronze strings, so we need to evaluate in x = 0.

We will get:

6*0 + 4.5*y = 90

4.5*y = 90

y = 90/4.5 = 20

He will buy 20 packs of nickel strings.

Two figures are similar when they have some common properties. The value of PQ as required is 28 units.

Similar triangles are two or more which have a series of common properties. This may be in relations to the length of their sides or measure of their angles.

In the given triangle PQR,

ΔPQS ll ΔSTR

Given that PS = RS, and QT = RT.

Then we can say that;

[tex]\frac{RS}{ST}[/tex] = [tex]\frac{PQ}{PQ}[/tex]

But, PR = 2RS;

[tex]\frac{RS}{ST}[/tex] = [tex]\frac{2RS}{PQ}[/tex]

[tex]\frac{1}{ST}[/tex] = [tex]\frac{2}{PQ}[/tex]

2ST = PQ

2(-22 + 9x) = 9x - 8

-44 + 18x = 9x - 8

18x - 9x = -8 + 44

9x = 36

x = 4

So that,

PQ = 9x - 8

     = 9(4) - 8

PQ = 36 - 8

     = 28

Thus, the length of PQ is 28 units.

The equivalent salary in Canadian dollars per hour of the driver is $28.13/hour.

To convert the annual salary of a truck driver in the US from US dollars to Canadian dollars, you can use the current exchange rate between the two currencies. The exchange rate fluctuates constantly, so you will need to use the most current rate.

Assuming the current exchange rate is 1 US dollar to 1.26 Canadian dollars, the annual salary of a truck driver in the US, $55,065, is equivalent to 71,040.90 Canadian dollars. If the truck driver works 70 hours per week and 52 weeks per year, their hourly wage in Canadian dollars would be $28.13.

Here's the calculation:

Annual salary in Canadian dollars = $55,065 * 1.26 = $71,040.90

Hourly wage in Canadian dollars = $71,040.90 / (70 hours/week * 52 weeks/year) = $28.13/hour

Keep in mind that this is just a rough estimate, as the exchange rate can change over time, and the actual wage may vary depending on the driver's experience, location, and other factors.

So, the equivalent salary in Canadian dollars per hour of the driver is $28.13/hour.

Answer:

  (a)  w = 13

Step-by-step explanation:

You have a regular quadrilateral with interior angle measure (6w+13)°, and you want the value of w to the nearest integer.

A regular quadrilateral is a square. Its interior angles are 90°, so we have ...

  6w +13 = 90

  6w = 77

  w = 12.833...

  w ≈ 13

Using mathematical operations, we can conclude that the length of LK is 1.25 units in triangle JKL.

A mathematical "operation" is indeed the method by which a value utilizes operands and a math operator.

The supplied operands or numbers must conform to a set of predefined rules that are connected to the symbol of the math operator.

Parentheses, Exponents, Arithmetic, Division, and Addition Simple arithmetic is also known as PEMDAS (from left to right).

So, we know that the given triangles are similar:

Then, the length of line LK will be:

JK/ST = LK/UT

Solve this as follows:

JK/ST = LK/UT

2.5/10 = LK/5

10LK = 2.5(5)

10LK = 12.5

LK = 12.5/10

LK = 1.25

Therefore, using mathematical operations, we can conclude that the length of LK is 1.25 units in triangle JKL.

0.3108 is the probability that a single tire randomly selected from the population will have a lifetime between 46,800 and 49,200 miles

Probability is a mathematical discipline that concerns with numerical figures of how probable an occurrence is to occur or how probably a statement is to be true. A number between 0 and 1 is the probability of an occurrence, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

X ~ N ( µ = 48000 , σ = 3000 )

As we know, P ( 46800 < X < 49200 )

Standardizing the  value, we get -

Z = ( X - µ ) / σ

Z = ( 46800 - 48000 ) / 3000

Z = -0.4

Z = ( 49200 - 48000 ) / 3000

Z = 0.4

Also,

P ( -0.4 < Z < 0.4 )

P ( 46800 < X < 49200 ) =  P ( Z < 0.4 ) - P ( Z < -0.4 )

P ( 46800 < X < 49200 )  = 0.6554 - 0.3446  (Probability calculated from Z table)

P ( 46800 < X < 49200 )  = 0.3108

Therefore in this question the probability that he is innocent is 0.1743

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Here,

In this case, let G represent the state of guilt and H represent the state of innocence.

and Let K stand for the situation where the truth serum shows that someone is guilty.

We are aware that 90% of the guilty suspects receive just verdicts, i.e. P(K|G)=0.9.

Additionally, we know that innocent suspects are mistakenly identified 1% of the time, or P(K|H)=0.01.

When a suspect is chosen from a group of suspects, of whom 5% committed a crime, and the serum suggests that the suspect is guilty, we must determine the likelihood that the suspect is innocent.

We must therefore determine the probability P(H|K).

A group of people was chosen for the suspect, of which 5% were criminals.

so the probability that selected person is guilty is

P(G) = 0.05

Therefore, the probability that selected person is not guilty is

P(H) = 1 – P(G) = 1 – 0.05 = 0.95

Then,

Using Bayes' Theorem, we get

P(H|K) =[tex]\frac{P(H)P(K|H)}{P(H)P(K|H) + P(G)P(K|G)}[/tex]

=     [tex]\frac{0.95*0.01}{0.95*0.01 + 0.05*0.9}[/tex]  =0.1743

Therefore in this question the probability that he is innocent is 0.1743

The given condition are-

Helen considers two numbers that fit the following criteria:

The steps to solve the condition are-

1. It is assumed that when Helen considers of two numbers, they have corresponding HCF and LCM values of 5 and 12.

2. A smallest common multiple shared by two numbers is referred to as the least common number.

LCM of 4 with 6 is 12, for instance.

3. The highest number which divides the two selected numbers, leaving a residue of 0, is referred to as the highest common factor.

HCF of 6 and 8 is 2, for instance.

4. Given that the LCM of Helen's two chosen numbers is 12, even multiples of 12 are indeed the two numbers' common multiples. In light of this, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, and so forth.

5. The only numbers that may be divided by 5 are 60 and 120. All other numbers have HCF values apart from 5. 60 and 120 have an HCF of 60, but not 5.

6. As a result, it is evident from the steps above that it is impossible to be have two numbers with the same LCM and HCF as 12 and 5, respectively.

The reqiured two digit number is 54

Let, a two-digit number be n

the digit at tens place as x and the digit at unit place be y

The tens digit of a two-digit number exceeds the units digit by 1.

x = y + 1                      .............(1)

if the number is divided by the sum of its digits, the quotient is 6.

(10x + y)/(x + y) = 6

Substitute above value of x in this equation.

(10(y + 1) + y) = 6(y + 1 + y)

10y + 10 + y = 6(2y + 1)

11y + 10 = 12y + 6

y = 4

Substitute above value of y in equation (1),

x = 4 + 1  

x = 5

So, the number would be, 10x + y = 50 + 4
