Let f(x) = 12 over the quantity of 4 x + 2. Find f(−1). (1 point)
mylen [45]

Answer:

-6

Step-by-step explanation:

Hope I understand your "f(x) = 12 over the quantity of 4 x + 2" correctly

f(x) = 12 / 4x +2

Now so they want a f(-1), as u can see they substituted the x for - 1, therefor do that the same to the right side

f(-1) = 12/ 4(-1) + 2

f(-1) = 12 / - 4+2

= 12/ - 2

= - 6

Last​ year, a person wrote 123 checks. Let the random variable x represent the number of checks he wrote in one​ day, and assume
Sunny_sXe [5.5K]

Answer:The mean number of checks written per​ day = 0.3370

The standard deviation = 0.5805

The variance = 0.3370

Step-by-step explanation:

Let the random variable x represent the number of checks he wrote in one​ day.

Given : The number of checks written in last year = 123

Let the number of days in the year must be 365.

Now, the mean number of checks written per​ day will be  :-

\lambda=\dfrac{123}{365}=0.33698630137\approx0.3370

We know that in Poisson distribution , the variance is equals to the mean value .

\text{Thus , Variance }=\sigma^2= 0.3370

\Rightarrow\ \sigma=\sqrt{0.3370}=0.580517010948\approx0.5805

Thus,  Standard deviation = 0.5805

What is the solution set for -4x - 10 ≤ 2?
hichkok12 [17]

Answer:

x <u>></u> -3

Step-by-step explanation:

- 4x - 10 <u><</u> 2

     + 10 <u><</u> + 10

<u>- 4x < 12</u>

-4      -4

x <u>></u> -3

I think the sign flips because the negative sign is w/the X.... If it doesn't, sorry 4 being wrong...
