Note that [tex]SR=2[/tex] and [tex]S'R'=4[/tex].

The scale factor is defined as the ratio of the length of the side of the image to the length of the corresponding side of the preimage.

a) The probability that the randomly chosen injury took place on a Thursday would be 0.17.

b) The probability that the injury took place on a weekday (Monday through Friday) would be 0.84.

c) The probability that it took place on a Monday would be 21.4%.

What is the probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 indicates that an event is impossible, and 1 indicates that an event is certain.

(a) To find the probability that the injury took place on a Thursday, we need to find the value of x in the probability table:

Day: Sunday Monday Tuesday Wednesday

Probability: 0.06 0.18 0.17 0.17

Day: Thursday Friday Saturday

Probability: x 0.15 0.09

The sum of the probabilities for each day must equal 1. So we can set up an equation to find x:

0.06 + 0.18 + 0.17 + 0.17 + x + 0.15 + 0.09 = 1

0.83 + x = 1

x = 0.17

The probability that the injury took place on a Thursday is 0.17.

(b) To find the probability that the injury took place on a weekday (Monday through Friday), we sum the probabilities for Monday, Tuesday, Wednesday, Thursday, and Friday:

0.18 + 0.17 + 0.17 + 0.17 + 0.15 = 0.84

The probability that the injury took place on a weekday is 0.84.

(c) Given that an injury took place on a weekday, we can use Bayes' Theorem to find the probability that it took place on a Monday. Let A be the event that the injury took place on a weekday, and B be the event that the injury took place on a Monday. Then:

P(B|A) = P(B and A) / P(A)

P(B and A) = P(B) = 0.18

P(A) = 0.84 (from (b))

So:

P(B|A) = 0.18 / 0.84 = 0.214 or 21.4%

The probability that the injury took place on a Monday, given that it took place on a weekday, is 21.4%.

Hence,

a) The probability that the randomly chosen injury took place on a Thursday would be 0.17.

b) The probability that the injury took place on a weekday (Monday through Friday) would be 0.84.

c) The probability that it took place on a Monday would be 21.4%.

The Poisson law states that the probability of at least 2 different changes daily is 0.0263. Thus, 0.0263% of changes happen twice or more each day.

The mathematical method it explains for calculating probability calculates all the probabilities of something occurring in the setting of specific random events. A probability's proximity to the unit value and, conversely, its distance from zero can make one less comfortable in the outcome. The confidence level is based on how close the probability value is, which is calculated using a range from 0 and 1

Here,

The conditional probability function for X is the amount of times the incident occurs over a specific period of time.

In this experiment, the frequency, or x, at which an event occurs is counted.

The likelihood of the event happening throughout each period is equal.

The number of events in one period is independent of the number in other intervals.

The first step is to set the discrete stochastic process X to the number of website content updates.

Let's say that there are on average x content changes every day.

The Poisson distribution law states that the probability of at least 2 changes each day is 0.0263.

Answer: A: 0.13

Step-by-step explanation:

To find the value of x in exponents and powers, we can use logarithm.

To find the value of x in an equation involving exponents or powers, you can use logarithms. The logarithm of a number is the exponent to which a base, such as 10 or e, must be raised to equal that number. The base of the logarithm is usually written as a subscript, so log base 10 of 100 is written as log10(100).

For example, if the equation is x^3 = 27, you can use logarithms to solve the equation by taking the logarithm of both sides with the same base. log(x^3) = log(27) and by using the logarithm properties we can simplify this to 3log(x) = log(27) and then divide both sides by 3 and x = 3.

The cost of 1 ft² grass sod is $3 and the cost of 1 geranium is $10.

This is found using simultaneous equations.

What are simultaneous equations?

A finite set of equations for which common solutions are sought is referred to as a set of simultaneous equations, often known as a system of equations.

Let,

    x = Cost of 1 ft² grass sod

   y = Cost of 1 geranium

In Shayna's case

Grass sod = 2ft²

Geranium bought = 1

Cost = $16

Equation

2x + y = 16 ⇒ (1)

In Arjun's case

Grass sod = 1 ft²

Geranium = 7

Cost = $73

Equation

x + 7y = 73 ⇒ (2)

Solving the equation (1) and (2)

From (1)

y = 16 - 2x

Substituting the above in (2)

x + 7 (16-2x) = 73

-13x = -39

  x = 3  

   y = 16 - 2*3 = 10

Therefore from the solution of the above simultaneous equations, we can conclude that the cost of 1 ft² grass sod is $3 and the cost of 1 geranium is $10.

The Values of missing angles are shown below.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

6. Using Angle sum property

<1 + 72 + 57 = 180

<1 = 51

Now, <2 +72 = 90

<2 = 18

<and, <3+ 57 = 180 (linear pair)

<3 = 123

Now, <4 = 180- 123- 18

<4 = 39

7. <1 = 180- 129 = 51 (linear pair)

<2 = 180- 51 - 95 = 34 (Angle sum property)

<3 = 95 (Vertical opposite angle)

<4= 180- 47 - 95 = 38

<5 = 47  (Vertical opposite angle)

<7= 180-121= 59

<6= 180-59-47= 74

8. Using Angle sum property

13x+ 2 + 5x - 7 + 3x -4 = 180

21x -9 = 180

21x = 189

x= 9

So, angles are 13x+2 = 119, 5x-7 = 38 and 3x-4 = 23

Answer: We can start solving this problem by using the information given: the ships are traveling in opposite directions and the speed difference between them is 12 mph. Let's call the speed of the ship heading east x and the speed of the ship heading west x-12.

We also know that the ships were 300 miles apart after 6 hours. The distance between the two ships can be represented as the sum of the distances traveled by each ship, which is x*6 + (x-12)*6 = 300.

We can use this equation to find the value of x.

x*6 + (x-12)*6 = 300

We can simplify it as:

x6 + x6 - 72 = 300

x12 - 72 = 300

x12 = 372

x = 31

So the ship heading east travels at 31 mph.

It is important to notice that the ship going west was 12 mph slower than the ship going east, so the speed of the ship going west is 31-12 = 19 mph.

It is also important to notice that the speed of each ship, x and x-12, are in the same units (mph) and also the distance, 300 miles, and the time, 6 hours, are also in the same units (hours and miles)

Answer:

y = -[tex]\frac{1}{2}[/tex]x+6

Step-by-step explanation:

First off, you need to know what slope-intercept form is: y = mx+b

y = mx+b

b = the y-intercept, or where the line meets with (0,y), which is value of the coordinate is the y-intercept.

Looking at your yellow dot on the y axis, (0,6), could be the perfect fit to find the y-intercept.

So, know we know: y = mx+6

m = the slope of the line - you have to find two coordinates

in this case, it could be the two yellow points

(0,6)

(6,3)

use the following two coordinates to find the slope:

[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

In this case, it would be 3-6/6-0, which equals to -1/2.

So, finally, we get:
