So the probability of it not snowing today is 0.7 or 70%.
what is probability?
Probability is a measure of the likelihood or chance of an event occurring. It is a numerical value between 0 and 1, where 0 indicates an impossible event and 1 indicates a certain event. Probability theory is a branch of mathematics that deals with the study of random events and their properties.
In the given question,
The complement of an event is the probability that the event does not occur. In this case, the complement of "it snows today" would be "it does not snow today".
To calculate the complement of an event, you can subtract the probability of the event from 1. So if the probability of it snowing today is 0.3 (or 30%), then the probability of it not snowing today would be:
1 - 0.3 = 0.7
So the probability of it not snowing today is 0.7 or 70%.

w(t) = _____
The linear function that models the baby's weight, w, as a function of the age of the baby, in months, t, is equals to the w(t) = 11 + (1/2)t.
The a straight line graph represents linear function. The linear function form is, y = f(x) = a + bx. It has an independent variable and a dependent variable. There is independent and dependent variables are x and y respectively. We have provide a scenario which consists the following informations,
The weight of new born baby = 11 pounds
The weight gained by new born baby in one month = 1/2 pounds
We have to determine a linear function which models the baby's weight (w pounds), as a function of the baby's age, in months (t). From the definition of linear function, we see here weight of baby is an dependent variable and month in first year is independent. So, the linear function of weight of baby is written as w(t) = 11 + (1/2)t , where t represents months in baby's first year. Hence, required function is w(t) = 11 + (1/2)t.

what is function?In mathematics, a function appears to be a connection between two sets of numbers in which each member of one set (known as the domain) corresponds to a specific member of the second set (called the range). In other words, a function takes input from a set and produces output from another. The variable x has now been frequently sometimes used represent the inputs, and the flexible y is used to represent the outputs. A formula or a graph can be used to represent a function. For example, the formula y = 2x + 1 represents a linear model in which each x-value yields a unique value of y.
So, g(x) = f(x + 3) = (x + 3)² = x² + 6x + 9.
g(x) = x² + 6x + 9
= 1(x² + 6x + 9)
= 1(x² + 6x + 9 + 9 - 9)
= 1((x + 3)² + 9 - 9)
= 1(x + 3)² + 0
Therefore, g(x) = 1(x + 3)² + 0, which is in the form a(x - h)² + k with a = 1, h = -3, and k = 0.

What is a function?
A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.
To determine if the function f: P(A) → P(A), where f(X) = A-X, is onto, one-to-one, neither, or both, we need to consider the following:
Onto: A function is onto if every element in the codomain has a corresponding preimage in the domain. In other words, for every Y in P(A), there exists an X in P(A) such that f(X) = Y.
Let Y be any subset of A. Then, we need to find an X such that f(X) = Y. Since f(X) = A-X, we need to find an X such that A-X = Y. Solving for X, we get X = A-Y. Therefore, we can choose X = A-Y, and we have f(X) = A-(A-Y) = Y. Hence, f is onto.
Next, we need to prove that f is not one-to-one. To do this, we need to find two different sets X1 and X2 such that f(X1) = f(X2).
Hence, the function f: P(A) → P(A), where f(X) = A-X, is onto but not one-to-one.

There are approximately 720 blue balls, 1080 red balls, 360 green balls, 540 orange balls, and 900 yellow balls in the bin.
How many of each color do you predict are in the bin?To predict how many of each color are in the bin, we can assume that the ratio of each color in the bin is the same as the ratio in the sample of 20 balls.
First, we calculate the total number of each color in the sample:
Blue: 4 balls

Green: 2 balls
Orange: 3 balls
Yellow: 5 balls
Next, we calculate the total number of balls in the sample:
4 + 6 + 2 + 3 + 5 = 20
Now, we can set up proportions to estimate the number of each color in the bin:
Blue: (4/20) * 3600 = 720
Red: (6/20) * 3600 = 1080
Green: (2/20) * 3600 = 360
Orange: (3/20) * 3600 = 540

For a $250,000 mortgage, with interest rate 6% paid over 25 years, the monthly payment is $1,610.75. After 2 monthly payments, what is the balance of the loan? Give your answer to the nearest dollar . Do not include commas or the dollar sign in your answer.
The balance of the loan after 2 monthly payments is $246,778 (rounded to the nearest dollar).
What is compounding?Compounding refers to the process of earning interest on both the principal amount and the interest earned on that principal over time. In other words, it is the process of reinvesting earnings so that those earnings can also earn money, creating a compounding effect.
Compound interest is calculated on the initial principal amount and also on the accumulated interest of previous periods. This means that the interest earned in each period is added to the principal, and the interest for the next period is calculated on the new total.
To find the balance of the loan after 2 monthly payments, we first need to calculate the total number of payments over the life of the loan. Since the loan is paid over 25 years with monthly payments, the total number of payments is:
25 years x 12 months/year = 300 months
Next, we can use the formula for the present value of an ordinary annuity to calculate the remaining balance after 2 monthly payments. The formula is:
PV = PMT x ((1 - (1 + r)⁻ⁿ) / r)
where PV is the present value or remaining balance, PMT is the monthly payment, r is the monthly interest rate, and n is the total number of payments.
The monthly interest rate is the annual interest rate divided by 12, so in this case, it is:
6% / 12 = 0.005
Plugging in the values, we get:
PV = $1,610.75 x ((1 - (1 + 0.005)⁻³⁰⁰) / 0.005)
PV = $240,902.43
This is the remaining balance after 2 monthly payments. To find the balance after the second monthly payment, we need to subtract two monthly payments from the original loan amount:
$250,000 - ($1,610.75 x 2) = $246,778.50
Therefore, the balance of the loan after 2 monthly payments is $246,778 (rounded to the nearest dollar).

what is the answer for ¼ +6 ⅓
Answer:
Step-by-step explanation: ¼ +6 ⅓;
= [tex]\frac{1}{4}[/tex] +[tex]\frac{19}{3}[/tex];
= [tex]\frac{3+76}{12}[/tex];
= [tex]\frac{79}{12}[/tex];
= 6[tex]\frac{7}{12}[/tex]
Step-by-step explanation:
Well to add fractions, you should make the denominator (denominator means the lower part for example 4 in ¼) the same for all numbers.
Forget the 6 for now, take only ¼ and ⅓ into consideration, make it have the same denominator
For 1/4 you multiply both up and down by 3 so it will become 3/12
For 1/3, multiply both by 4, so it becomes 4/12
You now have 3/12 and 4/12, let's not forget about the 6 now.
How do you obtain 6 if you have to make 12 denominator? (If you do 12×6 you get 72 right?) so 6 = 72/12
Your answer will be obtained like this
1/4 + 6 + 1/3 = 3/12 + 72/12 + 4/12 = 79/12 and you can make it a whole number if you can.
Ans : 79/12 which is also equal to 6 and 7 over 12 (6 7/12)

525 600

Therefore, the probability that a randomly selected light bulb will last between 750 and 900 hours is 0.4772, or 47.72%.
What is deviation?
The degree to which anything deviates from a norm or expected value is referred to as its deviation. The deviation of a collection of data from the average or mean value in statistics is a measurement of how dispersed the data are. Absolute deviation and standard deviation are the two different types of variance.
We may determine that, according to the 68-95-99.7 rule, 68% of the data is within one standard deviation of the mean, 95% is within two standard deviations, and 99.7% is within three standard deviations.
Here, we're trying to determine the likelihood that a randomly chosen light bulb would live between 750 and 900 hours. One standard deviation to two standard deviations above the mean define this range.
First, we need to standardize the values using the formula:
z = (x - μ) / σ
where x is the value, we want to standardize, μ is the mean, and σ is the standard deviation.
For x = 750
z = (750 - 750)/75 = 0
For x = 900
z = (900 - 750)/75 = 2
Now we need to find the area under the standard normal distribution curve between z = 0 and z = 2. We can use a table or calculator to find this area, which is approximately 0.4772.

How do functions work?Any subset of a Cartesian product is a relation.
A binary relation from A to B is made up of these ordered pairs (a,b), where the first component is from A and the second component is from B. Every item in a set X is connected to one item in a different set Y through a connection known as a function (possibly the same set). As an illustration, a subset of is referred to as a "binary connection from A to B," and more specifically, a "relation on A."

The odds in favor of it raining tomorrow are 1 to 6.
What is Probability ?
Probability can be defined as ratio of number of favourable outcomes and total number of outcomes.
To find the odds in favor of it raining tomorrow, we need to calculate the ratio of the probability that it will rain to the probability that it won't rain. The probability that it won't rain is 1 - 1/7 = 6/7.
So, the odds in favor of it raining are:
Probability of raining / Probability of not raining

A. Construct grouped frequency distribution for the above data.
B. Draw histogram, frequency polygon, less than and more than cumulative freq uency curve
A. To construct a grouped frequency distribution for the given data, we first need to determine the range of the data:
Range = Maximum value - Minimum value
Range = 39 - 5
Range = 34
Next, we need to decide on the width of each class interval. A common rule is to choose the number of classes to be between 5 and 20, and then choose a class width that is a convenient number. In this case, we will choose 8 classes and a class width of 5.
Class width = Range / Number of classes
Class width = 34 / 8
Class width ≈ 4.25
We can round up the class width to 5 to get a convenient number. The class intervals are:
5 - 9.99
10 - 14.99
15 - 19.99
20 - 24.99
25 - 29.99
30 - 34.99
35 - 39.99
40 - 44.99
Next, we count the number of observations that fall into each class interval. This gives us the frequency of each interval. The grouped frequency distribution is:
Class Interval Frequency
5 - 9.99 5
10 - 14.99 8
15 - 19.99 9
20 - 24.99 16
25 - 29.99 7
30 - 34.99 6
35 - 39.99 1
40 - 44.99 0
B. To draw the histogram, frequency polygon, and cumulative frequency curves, we first need to calculate the cumulative frequencies. The less than cumulative frequency is the running total of the frequencies up to each class interval, while the more than cumulative frequency is the running total of the frequencies from each class interval to the end.
Class Interval Frequency Less than Cumulative Frequency More than Cumulative Frequency

Answer:
For #17:
This is a 45-45-90 triangle. Therefore, the missing side length (x) is equal to the other leg of the triangle, which is 6.
For #18:
This is a 30-60-90 triangle. Therefore, the missing side length (m) is equal to the hypotenuse (18) divided by 2, or 9.
For #19:
This is a 30-60-90 triangle. Therefore, the missing side length (y) is equal to the hypotenuse (12) multiplied by the square root of 3, or 12√3.
For #20:
This is a 30-60-90 triangle. Therefore, the missing side length (u) is equal to the short leg (5√3) multiplied by 2, or 10√3.
For #21:
This is not a right triangle because the angles do not add up to 180 degrees.
For #22:
This is a right triangle because the angles add up to 180 degrees and one of the angles is 90 degrees.

coordinate points: (-5,-3),(-7,-11),(4,-13). give the coordinate of the fourth vertex
The coordinate of the fourth vertex is determined as (13,-23).
What is the coordinate of the fourth vertex?To find the fourth vertex of the parallelogram, we need to use the fact that opposite sides of a parallelogram are parallel and equal in length.
Let's start by finding the vectors for two sides of the parallelogram. We can use the given coordinate points to find the vectors:
Vector AB = (xB - xA, yB - yA) = (-7 - (-5), -11 - (-3)) = (-2, -8)
Vector BC = (xC - xB, yC - yB) = (4 - (-7), -13 - (-11)) = (11, -2)
Since opposite sides of a parallelogram are parallel, we know that these two vectors are parallel.
To find the fourth vertex, we can add the vector AB to the endpoint of vector BC:
Vector CD = Vector BC + Vector AB = (11, -2) + (-2, -8) = (9, -10)
Now we can add this vector to point C to find the coordinates of point D:
Point D = (xC + CDx, yC + CDy) = (4 + 9, -13 - 10) = (13, -23)
