A pergunta não está bem formatada. No entanto, pelo que parece óbvio

Responda:

3 horas

Explicação passo a passo:

Fração de hora gasta por sessão = 3/4 horas por sessão

Se o exercício for feito apenas aos domingos

Número de domingos por mês = 4

Portanto, número de sessões = 4

Fração de horas por sessão * Número de sessões

3/4 * 4 = 3 horas

Portanto, 3 horas são dedicadas ao exercício por mês

A travelling salesman sells milkshake mixing machines and on average sells 8.9 machines per month. He needs to sell at least 3 m
Goshia [24]

Answer:

0.67% probability he will have to shut down after this month

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the given time interval.

On average sells 8.9 machines per month.

So \mu = 8.9

Using the Poisson distribution, what is the probability he will have to shut down after this month

If he sells less than 3 machines.

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

P(X = 0) = \frac{e^{-8.9}*8.9^{0}}{(0)!} = 0.0001

P(X = 1) = \frac{e^{-8.9}*8.9^{1}}{(1)!} = 0.0012

P(X = 2) = \frac{e^{-8.9}*8.9^{2}}{(2)!} = 0.0054

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0001 + 0.0012 + 0.0054 = 0.0067

0.67% probability he will have to shut down after this month

A manufacturer determines that the cost of making a computer component is ​$4.191919. Write the repeating decimal cost as a frac
tankabanditka [31]

Let x=4.191919\ldots. Then 100x=419.191919\ldots. So

100x-x=99x=415

\implies x=\dfrac{415}{99}=4+\dfrac{19}{99}

Answer the thing on screen. Make sure to use the right &lt; or &gt; thing
BlackZzzverrR [31]

Answer:

12 \leq v

Step-by-step explanation:

first you subtract 7 from 7 and 12

19\leq v+ 7\\-7           -7

then you get 19 \leq v

(btw the variable always goes first with these problems)

so the final answer would be v \geq 12

I am working percentages increases and decreases with problems like From 24 pencils to 30 pencils (increase  question) or From 2
Fynjy0 [20]
24 pencils = 100%
30 pencils = ___%
30 - 24 = 6, so:

24 / 6 = 4 (it means that there are 4 sixes in 100%)
100% / 4 = 25%

Check: 25% * 24 = 25/100 * 24 = 1/4 * 24 = 6
30 - 6 = 24 (correct)
Answer: There was an increase by 25%

20 miles = 100%
11 miles = ___%
1 mile = 100% / 20 = 5%, so:

5 * 11 = 55 [percent]
100% - 55% = 45%

Check: 45% * 20 = 45/100 * 20 = 45/10 * 2 = 9/2 * 2 = 9
20 - 9 = 11 (correct)
Abswer: There was a decrease by 45%
