Answer:

The fraction version of this rectangle is 9/10. This is as much as we can simplify it and get a whole number. The decimal version of this would be 0.9.

Step-by-step explanation:

The fraction version: the answer is 9/10 because there are 10 segments, and 9 of them are shaded in. This is as much as we can simplify it because 10 cannot be divided by 9 or 3 and still get a whole number.

The decimal version: The answer is 0.9 because that rectangle represents 1. 0.9 represents the 9 sections shaded. the 1 unshaded one would be 0.1, and 0.9+0.1 is 1. So the answer is 0.9.

Find a formula for the inverse of the function. f(x) = e^6x − 9

STatiana [176]

Answer:

$f^{-1}(x)=\frac{1}{6}\ln(x+9)$

Step-by-step explanation:

So we have the function:

$f(x)=e^{6x}-9$

To solve for the inverse of a function, change f(x) and x, change the f(x) to f⁻¹(x), and solve for it. Therefore:

$x=e^{6f^{-1}(x)}-9$

Add 9 to both sides:

$x+9=e^{6f^{-1}(x)}$

Take the natural log of both sides:

$\ln(x+9)=\ln(e^{6f^{-1}(x)})$

The right side cancels:

$\ln(x+9)=6f^{-1}(x)$

Divide both sides by 6:

$f^{-1}(x)=\frac{1}{6}\ln(x+9)$

And we're done!

A machine produces small cans that are used for baked beans. The probabil- ity that the can is in perfect shape is 0.9. The prob

Elis [28]

Answer:

0.9783 = 97.83% probability that a can that gets shipped for use will be of perfect shape

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Shipped for use

Event B: Perfect shape

Probability of being shipped for use:

Perfect shape(0.9 probability) or unnoticeable dent(0.02 probability). So

$P(A) = 0.9 + 0.02 = 0.92$

Being shipped for use and being in perfect shape.

0.9 probability, so $P(A \cap B) = 0.9$

What is the probability that a can that gets shipped for use will be of perfect shape?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.9}{0.92} = 0.9783$

0.9783 = 97.83% probability that a can that gets shipped for use will be of perfect shape

Talia's gym membership costs $75 a month plus $30 additional for each month she brings a guest. Which equation shows the number

wel

Answer:

75 × 12 + 30m = 990

∴ m = 3

Step-by-step explanation:

Assume the number of months Talia brings a guest to be 'm'.

So the amount of Talia has to pay for guests for one year is $ 30m .

So, <em>total amount of money Talia has pay for one year = (monthly membership cost)×(number of months in a year) + (additional amount for guests)</em>

Total cost = $990

Monthly membership cost = $75

Number of months in a year = 12

Additional amount for guests = $ 30m

∴ The equation which gives you the number of moths she brought guests is:

990 = 75×12 + 30m

990 = 900 + 30m

990-900 = 30m

30m = 90

∴ m = 3
