Find an expression for f−1(x), if f(x) = 5 − 2x

Mathematics
1 answer:
Lesechka [4]3 years ago

Answer:

f^{-1}(x) = \frac{5-x}{2}

Step-by-step explanation:

Let y = f(x) and rearrange making x the subject

y = 5 - 2x ( add 2x to both sides )

2x + y = 5 ( subtract y from both sides )

2x = 5 - y ( divide both sides by 2 )

x = \frac{5-y}{2}

Change y back into terms of x

f^{-1} (x) = \frac{5-x}{2}

Irina18 [472]

When you write a number that is less than 1 in scientific notation how does the power of 10 differ from when you write a number greater than 1 in scientific notation?​

Answer : In scientific notation all numbers are written in the form m × 10ⁿ. If the number is less than 1, ten is raised to a negative power, so : m × 10⁻ⁿ.​

Example : a decimal number less than 1 is 0.02 = 2 x 10⁻² in scientific notation.

​Hope this helps!​​​​

Anvisha [2.4K]

Answer:

The probability that 6 or more women would be laid off is P=0.08.

Step-by-step explanation:

In this case, we have a group of people and a proportion of women and men. We can think of the people laid off as a random sample taken from the population (all employees of the department).

The right model to represent that is with a binomial distribution. In this case, the sample size is n=8 and the probability of picking a woman is p=0.44.

According to this model, the probability that 6 or more women, out of 8 persons, would be laid off is:
