Answer:

Step-by-step explanation:

The orientation of the triangle is reversed, so a reflection is required. Horizontal lines remain horizontal, but up/down are reversed, so the reflection is across a horizontal line. The horizontal line that is halfway between each point and its image is the line y = 2.5.

The x-coordinates of the image points are 1 less than the x-coordinates of the original, so a left shift of 1 unit is involved.

H(6) =.

The number in parentheses is the x value it will be equal to the y value.

When x = 6 the blue line is at y = 8

H(6) = 8

Answer:

0.4629 = 46.29% probability that the manager finds more than two such transactions

Step-by-step explanation:

For each transaction, there are only two possible outcomes. Either there is a procedural error, or there is not. The probability of a procedural error on a transaction is independent of any other transaction. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

A manager randomly selected 25 large cash transactions at a bank that were made in January.

This means that [tex]n = 25[/tex]

The chance for a procedural error is 10%

This means that [tex]p = 0.1[/tex]

What is the probability that the manager finds more than two such transactions?

This is:

[tex]P(X \geq 2) = 1 - P(X < 2)[/tex]

In which

[tex]P(X < 2) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{25,0}.(0.1)^{0}.(0.9)^{25} = 0.0718[/tex]

[tex]P(X = 1) = C_{25,1}.(0.1)^{1}.(0.9)^{24} = 0.1994[/tex]

[tex]P(X = 2) = C_{25,2}.(0.1)^{2}.(0.9)^{23} = 0.2659[/tex]

[tex]P(X < 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0718 + 0.1994 + 0.2659 = 0.5371[/tex]

[tex]P(X \geq 2) = 1 - P(X < 2) = 1 - 0.5371 = 0.4629[/tex]

0.4629 = 46.29% probability that the manager finds more than two such transactions

Using the binomial probability relation, the probability that more than 2 such transactions is made is 0.463

Given the Parameters :

Using the relation :

Substituting the values into the relation :

P(X > 2) = P(X = 3) + P(X = 4) +... + P(X = 25)

Using a binomial probability calculator :

P(X > 2) = P(X = 3) + P(X = 4) +... + P(X = 25)

P(X > 2) = 0.226 + 0.138 +... +..

P(X > 130) = 0.463

The probability that more than 2 such transactions is made is 0.463

Given:

[tex]\theta[/tex] is an angle in quadrant IV that has reference [tex]\dfrac{\pi}{3}[/tex].

To find:

The value of [tex]\sin \theta[/tex].

Solution:

We know that only cos and sec are positive in quadrant IV and all other trigonometric ratios are negative in quadrant IV.

Since [tex]\theta[/tex] is an angle in quadrant IV that has reference [tex]\dfrac{\pi}{3}[/tex], therefore the value of [tex]\sin \theta[/tex] must be negative.

[tex]\sin \theta=-\sin \dfrac{\pi}{3}[/tex]

[tex]\sin \theta=-\dfrac{\sqrt{3}}{2}[/tex]

Therefore, the required value is [tex]\sin \theta=-\dfrac{\sqrt{3}}{2}[/tex].

Answer:

20 hours

Step-by-step explanation:

[tex]\frac{15}{24}[/tex]=[tex]\frac{18}{x}[/tex]

15÷18=1.2

x=24÷1.2= 20 hours

20 hours is the answer

The time taken by 18 caterpillars to eat the entire Bush in Violetta's front yard is 20 hours.

Time taken is the inverse of the rate of work.

As it is given that the time taken by 15 caterpillars to eat all the leaves on the bush in Violetta's front yard is 24 hours, therefore, the rate at which the 15 caterpillars eat the leaves can be written as,

[tex]\rm Rate = \dfrac{\text{Number of Bush That caterpillars eat}}{\text{Time taken by the caterpillars}}[/tex]

[tex]\rm Rate = \dfrac{1}{24}[/tex]

Now, as it is the rate of 15 caterpillars, therefore, the rate of a single caterpillar can be written as,

[tex]\rm Rate = \dfrac{\frac{1}{24}}{15} = \dfrac{1}{24 \times 15}[/tex]

Now, the time taken by 18 caterpillars can be written as,

[tex]\rm Time\ taken = \dfrac{Work}{Rate \times 18}\\\\\rm Time\ taken = \dfrac{1}{\dfrac{1}{24 \times 15}\times 18}\\\\Time \taken = \dfrac{24 \times 15}{1 \times 18} = 20 \ hours[/tex]

hence, the time taken by 18 caterpillars to eat the entire Bush in Violetta's front yard is 20 hours.

Answer:

A) 65

B) 5

C) 242

D) 531

E) 36

Step-by-step explanation:

A) Let the unknown term be x.

Difference between 5 & 9 = 4

Difference between 9 & 17 = 8 = 4×2

Difference between 17 & 33 = 16 = 8×2

It is observed that the difference between two terms is getting doubled. So,

Difference between 33 & x = 16×2 = 32

∴ x = 33 + 32 = 65

B) Let the unknown term be x.

Difference between 20 & 12 = 8

Difference between 12 & 8 = 8/2 = 4

Difference between 8 & 6 = 4/2 = 2

It is observed that the difference between two terms is getting halved.

Difference between 6 & x = 2/2 = 1

∴ x = 6 - 1 = 5

C) Let the unknown term be x.

Difference between 2 & 8 = 6

Difference between 8 & 26 = 18 = 6×3

Difference between 26 & 80 = 54 = 18×3

It is observed that the difference between two terms is getting tripled.

Difference between 80 & x = 54×3 = 162

∴ x = 80 + 162 = 242

D) Let the unknown term be x.

Difference between 36 & 69 = 33

Difference between 69 & 135 = 66 = 33×2

Difference between 135 & 267 = 132 = 66×2

It is observed that the difference between two terms is getting doubled.

Difference between 267 & x = 132×2 = 264

∴ x = 267 + 264 = 531

E) Let the unknown term be x.

4 = 2²

9 = 3²

16 = 4²

25 = 5²

It is observed that all the terms in the sequence are squares of consecutive natural numbers.

So, x = 6² = 36
