The probability that it will NOT snow is 0.42
How to determine the probability that it will NOT snow?From the question, we have the following parameters that can be used in our computation:
Probability of snow = 0.58
The probability that it will NOT snow is the complement of the probability that it will snow
This is represented as
Probability that it will NOT snow = 1 - probability that it will snow
Substitute the known values in the above equation, so, we have the following representation
Probability that it will NOT snow = 1 - 0.58
Evaluate
Probability that it will NOT snow = 0.42
Hence, the value is 0.42

Explanation:
You are considering taking some courses at your local community college on a part-time basis for the upcoming school year. For a student who carries fewer than twelve credits (the full-time minimum), the tuition is $155 for each credit hour taken. All students, part-time or full-time, must pay a $20 parking fee for the semester. This fixed fee is added directly to your tuition and is included in your total bill. Write an equation to determine the total bill , t, for a student carrying fewer than twelve credit hours. Use n to represent the number of hours taken for the semester. Then, determine the total bill if you take nine credit hours. A. T + 20 = 155 n; $1395 b. T = 155 n + 20; $1395 c. T = 155 n + 20; $1415 d. T + 20 = 155 n; $1415.
The total bill if the student takes nine credit hours at the community college is T = $1415.
What are linear equations?One or more variables can be present in a linear equation, but their maximal possible power is only one. The graph of a linear equation will thus always be a straight line. Y = mx + b, where m denotes the line's slope and b its y-intercept, or point of intersection with the y-axis, is how linear equations are expressed. Many real-world situations, such as the connection between two variables or the distance travelled at a constant pace, may be modelled using linear equations. In order to obtain the value of the variable(s) necessary to make the equation true, one must use algebraic methods.
How to solve?
The total bill, t, for a student carrying fewer than twelve credit hours is given by,
T = 155 n + 20, where n represents the hours taken for semester.
The total bill if the student takes nine credit hours is T = 155(9) + 20 = $1415.

Step-by-step explanation:
for the first car 374/17 = 22 m per second
for bus 414/23 = 18 m per second
so the car is moving faster
car is moving faster than (22-18)=4 m per second from the bus
Answer: Car: 22 meters per second, Bus: 18 meters per second. The bus travels faster at 4 meters per second.
Step-by-step explanation: First, you should write a proportional relationship for meters per second so the car would be 374/17 and the bus would be written as 414/23. This is so you can know that you divide 374 by 17 to get 18, and 374 by 17 to get 22. So, you had it backward, the bus is faster by 4 meters per second, I hope this helped, for me (a 7th grader) this was review math, so I hoped this helped you.
A population of 50 foxes in a wildlife preserve doubles in size every 14 years. The function y = 50.2*, where x is the number of 14-year periods, models the population
growth. How many foxes will there be after 42 years?
After 42 years there will be foxes. (Type a whole number.)
Answer:
400
Step-by-step explanation:
You want to know the number of foxes predicted after 42 years by y = 50·2^x, where x is measured in 14-year periods.
Periods42 years is 42/14 = 3 14-year periods. Using x=3 in the equation, we predict ...
y = 50·2^3 = 50·8 = 400
foxes.
After 42 years, there will be 400 foxes.
__
Additional comment
It is often convenient to use time measured in 1-year periods. In that case, the equation could be written ...
y = 50·2^(t/14)
Then t/14 is the number of 14-year periods when t is in years.

Inequality is referred to in mathematics when a relationship results in a non-equal comparison between two expressions or two numbers. In this instance, any of the inequality symbols, such as greater than symbol (>), less than symbol (), greater than or equal to symbol (), less than or equal to symbol (), or not equal to symbol (), is used in place of the equal sign "=" in the expression. Polynomial inequality, rational inequality, and absolute value inequality are the various types of inequalities that can exist in mathematics.(- 2, - 4 )
- 4x + 4y = - 8 → (1)
4x - 6y = 16 → (2)
adding (1) and (2) term by term will eliminate x
0 - 2y = 8
- 2y = 8 ( divide both sides by - 2 )
y = - 4
substitute y = - 4 into either of the 2 equations and solve for x
substituting into (2)
4x - 6(- 4) = 16
4x + 24 = 16 ( subtract 24 from both sides )

What is the domain and range of the inverse? g. What is the relationship between the domains and range of a function and its inverse? h. Will the domain and range of all functions and their inverses follow this same pattern?
(a) This is the factored form of the equation.
(b) The x - intercepts are (√2, 0) and (-√2, 0).
(c) The value of f(-1) is -8.
What is x - intercept?
We set y = 0 and solve the equation for x to determine the x-intercept. This is due to the fact that the line crosses the x-axis at y=0. If an equation is not in the form y = mx + b, we can still solve for the intercepts by substituting 0 where necessary and then solving for the final variable. Set x = 0 and then solve for y to find the y-intercept.
(a) Consider, the given equation
f(x) = 8x^2 - 16
First to factor the equation.
Take 8 common from both the terms,
f(x) = 8(x^2 - 2)
This is the factored form of the equation.
(b) Now to find the x- intercept.
Let y = 8x^2 - 16
Set y = 0
So,
0 = 8x^2 - 16
8x^2 - 16 =0
x^2 - 2 = 0
x^2 = 2
x = ±√2
Hence, the x - intercepts are (√2, 0) and (-√2, 0).
(c) Now to find the value of f(-1)
plug x = -1 in the given equation.
f(-1) = 8(-1)^2 - 16
f(-1) = 8(1) - 16
f(-1) = 8 - 16
f(-1) = -8
Hence, the value of f(-1) is -8.
