A weather station in a major city in the Northwest kept data about the weather conditions over the past year. The probabilities

are displayed in the table below:
Hot Mild Cold
Sunny 0.15 0.30 0.10
Cloudy 0.10 0.25 0.10


If a random day is chosen from this data, what is the probability that the day was hot or sunny?

It's crucial to recognize that all necessary information is already presented in the question

The likelihood of a day being hot equals 0.15 + 0.10
                                                   = 0.25
The likelihood of a day being sunny amounts to 0.15 + 0.30 + 0.10
                                                        = 0.55
Combining the two probabilities, we find = 0.25 + 0.55
                                                                     = 0.80
Now
The probability of a day being both hot and sunny is 0.15
Thus
The probability of a day being either hot or sunny = 0.80 - 0.15
                                                               = 0.65
I trust this explanation is clear enough for your understanding.

Which function has no horizontal asymptote? F (x) = StartFraction 2 x minus 1 Over 3 x squared EndFraction f (x) = StartFraction
tester [12383]

Response:

f(x)=\frac{2x^2}{3x-1}

Detailed explanation:

The function  f(x)=\frac{2x-1}{3x} features a horizontal asymptote which is y=\frac{2}{3}

The function  f(x)=\frac{x-1}{3x} presents a horizontal asymptote which is y=\frac{1}{3}

One function f(x)=\frac{2x^2}{3x-1} lacks a horizontal asymptote  because the degree of its numerator surpasses that of the denominator,

The function  f(x)=\frac{3x^2}{x^2-1} displays a horizontal asymptote which is y=3

Zina [12379]
To calculate total earnings: 40 hours multiplied by $8.95 leads to earnings of $358. After deducting expenses, the total earnings would be $358 - ($35.24 + $24.82 + $21.33) = $276.61.

20 210
21 231
22 253
23 276
24 300

Here’s a chart to aid in understanding the staircase issue. Observe that for 1 step, there is 1 block; for 2 steps, 3 blocks; for 3 steps, 6 blocks, and so forth. Note that the blocks corresponding to each step are a combination of that step and all the blocks used in the steps beneath it. For instance, constructing 14 steps requires 105 blocks.
If you’re familiar with summation, you would sum the blocks for each step with all the steps below it. For example, 5 steps would require 5 + 4 + 3 + 2 + 1, resulting in a total of 15 blocks. I hope this helps you begin. As for the second part, I'm confused by the problems since they don't represent equations. NO equal signs
