if you are tossing a six-sided die, what is the probability of getting either a 1 or a 2 on your first toss and your second toss?
It is based on the likelihood of something occurring. The reasoning behind probability is the foundation of theoretical probability. The probability of getting one or two in first and second toss is [tex]\frac{1}{9}[/tex].
Probability is a number that represents the likelihood or chance that an event will occur. Probabilities can be expressed as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.
The probability of getting one or two in first toss will be:-
[tex]\frac{1}{6} + \frac{1}{6} = \frac{1+1}{6} = \frac{2}{6} = \frac{1}{3}[/tex] ( as the probability of getting one in first toss is [tex]\frac{1}{6}[/tex] and getting two is also [tex]\frac{1}{6}[/tex]).
Similarly the probability of getting one or two in second toss will be:-
[tex]\frac{1}{6} +\frac{1}{6} = \frac{1+1}{6} = \frac{2}{6} = \frac{1}{3}[/tex]
The total probability of getting one or two in first and second toss will be:-
[tex]\frac{1}{3} *\frac{1}{3} = \frac{1}{9}[/tex]
Hence, Henceprobability is [tex]\frac{1}{9}[/tex].

Answer:
2. y = 3x + 6
3. y = 2x
4. y = 5x + 60
Step-by-step explanation:
Slope-intercept form: y = mx + b
2.
Pick 2 points (0,6) (1,9)
The y increase by 3, and the x increase by 1, so the slope is
m = 3
the y-intercept is located at (0,6)
Our equation is y = 3x + 6
3.
Pick 2 points (0,0) (1,2)
The y increase by 2, and the x increase by 1, so the slope is
m = 2
the y-intercept is located at (0,0)
Our equation is y = 2x
4.
Pick 2 points (0,60) (2,70)
The y increase by 10, and the x increase by 2, so the slope is
m = 10/2 = 5
the y-intercept is located at (0,60)
Our equation is y = 5x + 60

The appropriate sales price for a home in 2020 would be = 480 thousands. That is option A.
How to calculate tye appropriate sales price?The price of home in year 1990 = 149 thousand
The price of home in the year 1995 = 158 thousand
The difference in years = 2000-1995 = 5 years
The difference in the average sales price for the both years = 158-149 = 49 thousand.
The years difference between 2000 and 2020 = 20 years
If 5 years = 49 thousand
20 years = X
Make X the subject of formula;
X = 20×49/5
X = 980/5
X = 196 thousand
Therefore, the sales price for a home in 2020 would be = 207+196 = 403 thousands. The appropriate sales price would be = 480 in 2020.

In elimination for linear equations
The solution to the given system of linear equations is (x, y) = (-1, 1).
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The system of equations is given in the question, as follows:
-6y + 2 = 4x
y - 2 = x
Here's how to solve this system of equations using the elimination method:
Multiply the first equation by 2:
-12y + 4 = 8x
Add the two equations:
-12y + 4 + y - 2 = 8x + x
-11y + 2 = 9x
Solve for x:
x = (2 - 11y)/9
Substitute the value of x back into one of the original equations to find y:
-6y + 2 = 4x
-6y + 2 = 4((2 - 11y)/9)
-6y + 2 = (8 - 44y)/9
-54y + 18 = 8 - 44y
26y = 26
y = 1
Use the value of y to find x:
x = (2 - 11y)/9
x = (2 - 11 * 1)/9
x = (2 - 11)/9
x = -9/9
x = -1
Thus, the solution is (x, y) = (-1, 1).

If the average service rate is 6 customers per hour, and assuming the negative exponential distribution is used to describe the randomness of the service time distribution. The probability that the service time will be less than or equal to 6 minutes is 0.549 [B]
The average service rate of 6 customers per hour corresponds to a mean service time of 1/6 = 0.1 hour = 6 minutes. To find the probability that the service time will be less than or equal to 6 minutes, we need to find the cumulative distribution function (CDF) of the exponential distribution evaluated at 6 minutes. The CDF of the exponential distribution is given by:
F(x) = 1 - exp(-λx)
where,
λ = 1/mean = 1/0.1 = 10. Plugging in x = 6, we get:

The selling price of the bags of almonds that yields a profit of 45% is $420.5
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables using mathematical operations. An equation can be linear, quadratic, cubic and so on, depending on the degree of the variable.
The formula for profit is given by:
Profit = [(selling price - cost price) / cost price] * 100%
At the nut farm, the cost price of a bag of almonds is R290. It is sold with a profit of 45%. Hence, substituting:
45% = [(selling price - 290)/290] * 100%
0.45 = (selling price - 290)/290

an orchard owner is investigating a new formula of fertilizer to determine if it produces more apples per tree compared to a current popular brand.part a: which of the following design is most appropriate: observational study, experiment, census, or sample survey? explain your reasoning. (3 points)part b: explain how you would implement the design you selected in part a. (4 points)part c: explain one benefit your design would provide. (3 points)
The most appropriate design would be experiment. Implementation of the design would be by selection of trees, then the application of fertilizer, followed by data collection and statistical analysis.
a) Most appropriate design: Experiment
The orchard owner wants to determine if a new formula of fertilizer produces more apples per tree compared to a current popular brand. To make a causal conclusion, an experiment would be the most appropriate design. In an experiment, the orchard owner would randomly assign the trees to receive either the new fertilizer formula or the current popular brand and then compare the number of apples produced. This allows the orchard owner to control for other variables and isolate the effect of the fertilizer on the number of apples produced.
b) Implementation:
Selection of trees: The orchard owner would randomly select a sample of trees from their orchard and divide them into two groups: the experimental group (receiving the new fertilizer formula) and the control group (receiving the current popular brand).
Application of fertilizer: Both the experimental and control groups would receive the same amount of fertilizer, but the experimental group would receive the new formula while the control group would receive the current popular brand.
Data collection: The orchard owner would measure the number of apples produced by each tree in both the experimental and control groups.
Statistical analysis: The orchard owner would use appropriate statistical tests to compare the number of apples produced by each group and determine if there is a significant difference between the two.
c) Benefit:
One benefit of this experimental design is that it allows the orchard owner to determine causality. By randomly assigning the trees to receive either the new fertilizer formula or the current popular brand, the orchard owner can be confident that any difference in the number of apples produced is due to the fertilizer and not other factors. This is important for making decisions about which fertilizer to use in the future.

What is function?A function is an equation with just one solution for y for every x. A function produces exactly one output for each input of a certain type. Instead of y, it is usual to call a function f(x) or g(x). f(2) indicates that we should discover our function's value when x equals 2. Example. A function is a type of rule that produces one output for one input. Alex Federspiel provided the image. y=x2 is an example of this. If you enter anything for x, you will only get one output for y. Because x represents the input value, we may say that y is a function of x.
Here,
Given the functions s(x) = 5 and t(x) = 3, we can find the expressions for (s + t)(x) and (s - t)(x) as follows:
(s + t)(x) = s(x) + t(x) = 5 + 3 = 8
(s - t)(x) = s(x) - t(x) = 5 - 3 = 2
To evaluate (s - t)(-1), we simply plug in -1 for x in the expression for (s - t)(x):
(s - t)(-1) = 2

Oldfield mice come in a variety of colors; fawn-colored (medium or dark) individuals are typically found in inland regions, whilst lighter or white individuals are found in coastal regions. As a result, Santa Rosa Island should have more colored mice and the beach should have more light-hued mice.

question 11 pts suppose is an -matrix such that has only the trivial solution. how many pivot columns does have?
A matrix A is said to have only the trivial solution if the only solution to the system of equations, A x = 0, is the zero vector, x = 0.
The number of pivot columns in a matrix is equal to the rank of the matrix. Therefore, if A has only the trivial solution, it has rank 0, and so it has 0 pivot columns. To calculate the rank of a matrix, we can use the following formula: rank(A) = min(m, n) - dim(null A), where m and n are the number of rows and columns of A, respectively, and dim(null A) is the dimension of the null space of A.
