The length of a pencil is measured with two rulers. Report the length of the pencil from each ruler with the proper number of di
babunello [11817]

Answer

Length measured with Ruler A= 1.17 dm

Length measured with Ruler B= 1.18 dm

Step-by-step explanation:

I included a missing image that shows the pencil's length as measured using two rulers.

Ruler A has a scale marked at 1 dm intervals.

Ruler B has a scale marked at 0.1 dm intervals.

Length measured with Ruler A= 1.17 dm

(The middle markings reveal that the pencil tip lies between 1 and 1.25, slightly above 1.125 but below 1.25, positioning it around 1.2 and 1.125 dm, approximately half of 1.25, which is 1.125, plus an increment of one of the three halves of that half, which gives 1.125+0.045 dm thus concluding to 1.17 dm.)

Length measured with Ruler B= 1.18 dm

(The pencil tip appears just shy of 1.2 dm, confirming the precise value is clearly 1.18 and not 1.19 dm.)

Tip: When unsure about the exact measure, it’s advisable to estimate one extra decimal beyond what the ruler presents.

PIT_PIT [12445]
Customer arrivals at a fast-food outlet conform to a Poisson distribution with an average rate of 16 customers per hour. In statistical probability analysis, the Poisson distribution is a commonly utilized discrete probability distribution. Employing the formula, it has been calculated that 0.0661 represents the probability of there being precisely 12 arrivals in the next hour.

Write a rule that would allow you to test whether (x,y) is on line ℓ.
lawyer [12517]

Response:

We define a line L.

In a two-dimensional space, a line can be expressed as follows:

y = a*x + b

where 'a' denotes the slope and 'b' represents the y-intercept.

To determine the slope for a line passing through points (x1, y1) and (x2, y2), the formula is:

a = (y2 - y1)/(x2 - x1).

Using one of these points will help to find the value of 'b'.

Once we have the line's equation:

y = a*x + b

we can substitute in a specific point (x, y)

to verify if the equation holds true. If it does, that point lies on the line L.
