a) $\log \left(\dfrac{A^3B}{C} \right) = 3\log A + \log B - \log C$

b) $\log \left(\dfrac{\sqrt{A}}{B^2} \right) = \frac{1}{2}\log A - 2\log B$

It takes 212121 minutes for 555 people to paint 777 walls. How many minutes does it take 333 people to paint 555 walls?

Papessa [141]

Solution: We are given that:

5 people can paint 7 walls in 21 minutes

Therefore, 1 person can paint 7 walls in $21 \times 5=105$ minutes

Which means 1 person can paint 1 wall in $\frac{105}{7} =15$ minutes

Now, 3 people can paint 1 wall in $\frac{15}{3} =5$ minutes

Therefore, 3 people can paint 5 walls in $5 \times 5=25$ minutes

Last year, a person wrote 139 checks. Let the random variable x represent the number of checks he wrote in one day, and assume

viktelen [127]

Answer:

Mean = 0.38082 checks per day

Variance = 0.38082

Standard deviation = 0.61711

Step-by-step explanation:

In a Poisson distribution, the variance (V) is equal to the mean value (μ), and the standard deviation (σ) is the square root of the variance.

A year has 365 days,, if 139 checks were written during a year, the mean number of checks written per day is:

$E(x)=\mu=\frac{139}{365}\\ \mu=0.38082\ checks/day$

Therefore, the variance and standard deviation are, respectively:

$V=\mu=0.38082\\\sigma=\sqrt{V}=\sqrt{0.38082}\\ \sigma =0.61711$
