Form given information, the probability of rain in Nevada, the probability that it will not rain is 0.7
The probability that if it does not rain, the school bus will be on time is 0.85
The probability that it will rain and the school bus will still be on time is 0.6
In this question, we have been given the probability of rain in Nevada is 0.3
If it rains, the probability of the school bus being late is 0.4
If it does not rain, the probability of the school bus being late is 0.15
We need to find the probability that
a) it will not rain
b) If it does not rain, the school bus bring on time
c) it will rain and the school bus will be on time
The probability that it will not rain in Nevada:
= 1 - probability of rain in Nevada
= 1 - 0.3
= 0.7
The probability that if it does not rain, the school bus will be on time is:
= 1 - probability of the school bus being late if it does not rain
= 1 - 0.15
= 0.85
The probability that it will rain and the school bus will still be on time is:
= 1 - probability of the school bus being late if it rains
= 1 - 0.4
= 0.6
Therefore, the probability of rain in Nevada, the probability that it will not rain is 0.7
The probability that if it does not rain, the school bus will be on time is 0.85
The probability that it will rain and the school bus will still be on time is 0.6

What is (-1, 2) reflected across the y-axis?
If the coordinate is reflected over the y-axis, the resulting coordinates will be (1, 2).
Reflection of coordinatesImages that are reflected are mirror images of each other. For instance, given the coordinate points (x, y), if it is reflected across the y-axis, then the result of the expression is (-x, y).
Given the coordinate point (-1, 2), if the coordinate is reflected over the y-axis, the resulting coordinates will be (1, 2).
Note that the x-coordinate point is negated if the coordinate is reflected over the y-axis.

Hazel plans to mow her neighbors' yards to earn money. She charges a base fee of $25 and $7 for every hour she mows. The amount she earns per yard can be represented by the linear function M(t) = 7t + 25. What is the value of M(2), and what is its interpretation?
a. M(2) = 39; If Hazel mows 2 yards, she will earn $39.
b. M(2) = 14; If Hazel mows 2 yards, she will earn $14.
c. M(2) = 39; If Hazel mows a yard for 2 hours, she will earn $39.
d. M(2) = 14; If Hazel mows a yard for 2 hours, she will earn $14.
The correct option is M(2) = 39; If Hazel mows a yard for 2 hours, she will earn $39 . Option C
What is a function?A function can be defined as an expression that shows the relationship between an independent variable and a dependent variable.
Given the function;
M(t) = 7t + 25
Where;
M is the amount she earns per yardt is the time in hoursFor M(2), we substitute the value of t as 2 in the function
M(2) = 7(2) + 25
M(2) = 14 + 25
M(2) = $39
This explains that the she mows the yard for t = 2 hours, she would earn $39
Thus, the correct option is M(2) = 39; If Hazel mows a yard for 2 hours, she will earn $39. Option C

Value of x is -1, when :

From the given examples 5z - 3x = -3x + 5z and 5(xy) = 5(xy) are following the commutative property.
According to the given question.
We have some equations
2x + 3x = 5x
5xy = 5(xy)
5z - 3x = -3x + 5z
3(a + b) = 3a + 3b
Here, we have to find which equation is following the commutative property.
As we know that, the commutative property is a math rule that says that the order in which we multiply numbers does not change the product.
For, example 4 + 5 gives 9, and 5 + 4 also gives 9.
From the given example the equation
5z - 3x = -3x + 5z is following the commutaive property of addition.
And, 5(xy) = 5(xy) is following the commutative property of multiplication.

5. The average monthly salary among a firm's twelve employees is 3500 € There are two part-time workers in the firm who both earn 2500 €/month. If the salaries of these two part-time workers are excluded from the average, what will the new average salary be? a) 3700 € b) 4300 € c) 4000 € d) other
Answer:
Choice a) 3700 €
Step-by-step explanation:
Total salary among 12 workers = Avg Salary x 12 = 3500 x 12 = 42,000 €
Total salary of 2 part-timers = part-time avg x 2 = 2500 x 2 = 5000
Total salary without part-timers salary= 42,000 - 5000 = 37,000 €
If we exclude the 2 part-timers, there are 10 full-timers who earn 37,000 €
So new Average Salary = 37000/10 = 3,700 €

Mr. McDowell bought a block of fudge that weighed 7/10 of a pound. He cut the fudge into 7 equal pieces. What was the weight of each piece of fudge?
Answer: 1/10 of a pound
Step-by-step explanation:
The total weight was 7/10 of a pound. Cutting the fudge into 7 pieces implies dividing the fudge by 7.
7 is the same as 7/1.
When dividing fractions, we can multiply by the reciprocal. Essentially, we just flip the second number.
[tex]\frac{7}{10}/7 =\frac{7}{10} / \frac{7}{1} =\frac{7}{10} *\frac{1}{7}[/tex]
We can multiply this out to 7/70 and then simplify to 1/10,
or we could first cross simplify by dividing the 7s out of the numerator and denominator before multiplying. Either way, your answer ends up being 1/10 of a pound.

An observation deck extends 456 feet out above a valley. The deck sits 406 feet above the valley floor. If an object is dropped from the observation deck, its height h in feet, after t seconds, is given by h=-161 +406. How long will it take for the object to be 6 feet above the valley floor?
We need to know the relation between height, time to solve this problem. The time taken by the object to be 6 feet above the valley floor is 25 seconds.
The distance an object falls is proportional to the time it took to fall because of gravitational force. Here we have been given an equation that shows us the relation between height of the object and the time taken to reach that height. We know that the initial height of the object is 406 feet, if we substitute the initial height in the equation we get time to be zero which shows us that this is the initial height. We need to find out the time taken by the object to be 6 feet above the valley floor.
h= -16t+406
6=-16t+406
-400=-16t
t=400/16=25 seconds
Therefore the time taken by the object to be at a height 6 feet above the valley floor is 25 seconds.
