The estimated probability that at least one of the next four fish Roxanne catches will be a perch is 34%

<h3>What is Probability ?</h3>

Probability is the likeliness of an event to happen. It has a range of 0 to 1, where 0 indicates uncertainty and 1 indicates certainty.

It is given that

0, 1, and 2 represent trout , 3 and 4 represent bass , 5 represent perch , 6, 7, 8, and 9 represent other fish

From the data it can be observed that

Total number of single digits numbers = 80

No. of Perch , "5 " = 8

Probability of getting a perch in next fish = 8/80 = 0.1

Probability that at least one of the next four fish Roxanne catches will be a perch = 1- P(no perch)

P ( no perch) = 1 - 0.1 = 0.9

for 4 fishes

= 1 - 0.9⁴

= 0.3439

= 34.39%

≈ 34%

Therefore the estimated probability that at least one of the next four fish

Roxanne catches will be a perch is 34%.

Given f(x)=-1/7√16-x^2 find f^-1(x)

Vera_Pavlovna [14]

Answer:

$f^{-1}(x)=\pm \sqrt{49x^2-16}$

Not a function.

Step-by-step explanation:

The given function is;

$f(x)=-\frac{1}{7}\sqrt{16-x^2}$

Let $y=-\frac{1}{7}\sqrt{16-x^2}$

Interchange x and y;

$x=-\frac{1}{7}\sqrt{16-y^2}$

Solve for y;

$-7x=\sqrt{16-y^2}$

Square both sides

$(-7x)^2=(\sqrt{16-y^2})^2$

$49x^2^2=16-y^2$

$49x^2^2-16=y^2$

$y=\pm \sqrt{49x^2-16}$

The inverse is

$f^{-1}(x)=\pm \sqrt{49x^2-16}$

$f^{-1}(x)=\pm \sqrt{49x^2-16}$ is not a function because one x-value maps onto to different y-values.

In which number does the digit 4 have a value that is 10 times as great as the value of the digit 4 in 348,971? 284,796 or 327,4

Doss [256]

Answer:

The number is 492,875.

Step-by-step explanation:

Given:

A number that is = $348,971$

Place value of 4 = $40,000$

Place value is ten thousands.

We have to identify the number where the place value of 4 is 10 times of the given number.

Numbers given:

284,796 or 327,498 or 492,875 and 742,186.

Lets see the place value of 4 in each of the number.

⇒

$284,796$ place value of $4$ is $4,000$ .
Place value of 4 is thousands.

⇒

$327,498$ place value of $4$ is $400$ .
Place value of 4 is hundreds.

⇒

$492,875$ place value of $4$ is $4,00,000$ .
Place value of 4 is hundred thousands.

⇒

$742,186$ place value of $4$ is $40,000$ .
Place value of 4 is ten thousands.

Notes:

Ten thousands multiplied with ten is hundreds thousand.

⇒ $10,000\times 10 =1,00,000$

So,

The number which has digit 4 as hundred thousands place values is 492,875.
