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.

Solve the system. x + y = 8 2x2 – y = –5 Add the equations, then choose the result. 3x2 = –13 3x2 = 3 2x2 + x = 3 2x2 = –13
tester [8808]
2x^2 - y = -5
     x + y = 8
----------------adding gives us
2x^2 + x = 3 <==

** It's important to note that 2x^2 and x cannot be combined, because they are not like terms.

An experiment was done to look at whether there is an effect of the number of hours spent practising a musical instrument and ge
Svet_ta [9486]

Answer: Repeated contrast

Step-by-step explanation:

The conducted two-way ANOVA involved 30 participants, split evenly between 15 males and 15 females, all of whom had no prior experience with musical instruments.

This ANOVA analysis included repeated measures and considered within-group effects, between-group effects, and interaction effects. The findings indicated a significant main effect based on gender and the hours practiced. Therefore, the repeated contrast approach will be employed to assess the gender influence. This method evaluates the mean of each level in relation to the next, excluding the final level.

12-5x-4kx=y solve for x
PIT_PIT [9101]
12-5x-4kx=y:x 

-5x-4kx=y-12 

-x(5+4k)=y-12 

-x= \dfrac{y-12}{5+4k} 

x=- \dfrac{y-12}{5+4k}

At the Zamenhof Language School, at least 70% of the students take English each year, at least 40% take German each year, and be
PIT_PIT [9101]

Answer:

(C) 10% to 70%(

Step-by-step explanation:

Given that at least 40% of the students are learning German, the upper limit of those who might be enrolled in English but not in German is 60%. However, since a minimum of 70% study English, it leads to the conclusion that at least 10% of students must be taking both German and English.

If we consider that at least 30% of students are learning Italian, and assuming that no student is studying all three languages simultaneously, then there is a maximum of 70% of students who could potentially be registered in both English and German.

This means the possible percentage for students enrolled in both English and German ranges from 10% to 70%
