The probability that the retailer sells no more than one house in a month is 0.60.

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes and how likely they are to happen. The analysis of events governed by probability is called statistics.

The given is a probability distribution. The probability density function or PDF of the probability is defined for the random variable x, where x ranges from 0 less than or equal to x less than or equal to 2 ie the range of x is from 0 to 2 with 0 and 2 inclusive.

x    :      0          1           2

p(x):   0.20    0.40     0.40

The probability that the retailer sells no more than one house in a month is given by

P(x less than or equal to one) = P(0) + P(1)

=0.20 + 0.40 = 0.60.

Given: The expression y = 3.5x + 2.8 calculates the y (in dollars) cost of an x-mile taxi fare. You have enough cash to take a cab for a maximum of 20 kilometres.

Domain and range to find

Solution:

y = 3.5x + 2.8

Using One way ANOVA and Randomized block design, the sum of squares between groups (ssb) is equal to the sum of sum of sum of explantary variable A's sum of squares and errors sum of square.

Statistics uses one-way ANOVA to compare the means of three or more independent groups to determine if there is a statistically significant difference between the corresponding population means. It is constructed using the sum of squares measure of total variability used in the numerator of the standard deviation, subtracting the mean, squaring the difference, and adding all observations to obtain the total variability Generate a scale. For multiple groups, we focus on decomposing this total variability (total sum of squares) into the variability between means (the sum of squares of the explanatory variable A) and the variability of the residuals or errors (the error sum of squares).

SSTotal = sum of squares = ∑( yᵢ - Y )²

Total variation is assessed by the total mean (the estimated mean of all observations, available from mean-only models).

SSA = Sum of Squares of Explanatory Variable A

Also called treatment, regression, or model sum of squares. ∑∑(yᵢⱼ - Y' )²

SSE = error (residual) sum of squares

Variation of response around group mean.

Also called the sum of squared residuals.

SSE = ∑∑( Y - Y')²

The total sum of squares is always equal to the sum of the sum of the squares of the explanatory variable A and the sum of the squared errors, SST (total) = SSA + SSE. This equation means that if SSA increases, SSE must decrease if SSTotal remains the same. This result is called the sum of squares decomposition formula.

In the given question,

We have to simplify the given expression.

Before simplifying the expression we first learn that the negative power can be positive after changing their position from numerator to denominator.

We use the method of adding the power of expression to solve the expression.

(1) The given expression is [tex](-\frac{1}{4}w^{-1}z^{-2})^{-3}[/tex].

We firstly simplifying the power after the bracket by multiplying the power to each variable.

[tex](-\frac{1}{4}w^{-1}z^{-2})^{-3}=(-\frac{1}{4})^{-3}(w^{-1})^{-3}(z^{-2})^{-3}[/tex]

Simplifying the expression.

[tex](-\frac{1}{4}w^{-1}z^{-2})^{-3}=(-1)^{-3}(\frac{1}{4})^{-3}(w^{-3})(z^{6})[/tex]

Now we make the power positive by changing their position

[tex](-\frac{1}{4}w^{-1}z^{-2})^{-3}=(-1){4}^{3}(w^{-3})(z^{6})[/tex]

Simplifying

We can use both regular and strong induction.

The Fundamentals of Inductive Mathematics (i.e., Regular Induction). If any of the following statements involving a positive number, n, are accurate: The claim is true if and only if n is 1. If the assertion is true for n=k, then it must also be true for n=k+1(x).

In a variation of induction known as strong induction, we make the assumption that the assertion is true for all values before k. This provides us with more information with which to work.

Regular Induction form

N>6 = n=7 in basic case

3n = 37 = 2187

N! = 7! = 5040

For n= 7 3n<n! is true

Induction hypothesis

Let for n= k and k>6

Assume 3k<k! is true

We prove that for k = k+1 the assumption holds true then the assumption must be true for k

K = k+1

3k+1 < (k+1)!

3k. 3 < (k+1) k!

3k < (k+1)/3.k!

For k>6

(k+1)/3 >1 and let (k+1)/3 = p

3k < P.k!

But we assumed that 3k < k! for k > 6 then 3k must be less than p.k1 since P>1

Therefore 3k<k! for k>6

3n < n! for all integers n greater than 6.

A minimum of 71 observations must fall inside the interval (20, 40).

It is true that Chebyshev's Theorem holds true for all conceivable data sets. The minimal percentage of measurements that must fall within one, two, or more standard deviations of the mean is described. The minimum percentage of observations that are within a given range of standard deviations from the mean is calculated using Chebyshev's Theorem. Numerous other probability distributions can be applied with this theorem. Chebyshev's Inequality is another name for Chebyshev's Theorem.

Given,

The data set has 80 observations and has mean 30 and standard deviation 5.

Chebyshev's theorem states that for each data set, the proportion (or percentage) of values ​​that lie within k standard deviations of the mean (that is, the interval (x -ks , x +ks) is at least 1-1/k² . where k > 1.

x = 30

s = 5

Three standard deviations are added to and subtracted from the mean to get the interval (10, 40).

(30 - 3.5, 30 + 3.5) = (10, 40)

According to Chebyshev's Theorem, this interval contains at least 1 -1/3² = 8/9 of the data. Given that 8/9 of  80 is 71.11, the interval must include at least 71.11 observations. However, one cannot make a fractional observation, so we draw the conclusion that the interval must contain at least 71 observations.

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution.

Here,

The chances of seed to be not growing is 1–0.95 =0.05.

For 3 seeds not to grow being simultaneous occurring events have the probability = 0.05×0.05x0.05=0.000125

As 9 seeds being planted the probability of selecting 1 out of 9 is (1/9).

Y-int = -45, X-int =-11.25

Step-by-step explanation:

Please read this before moving on :)

An intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+b, where m is slope and b is the y-intercept.

We know that equation of a line is y=mx+b. To find the value of the x-intercept of the line we simply need to put the value of the y as 0.

Using the Slope Equation : Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

2 points; (0,-40), (-10,0)

0-(-40)/(-10)-0 = 40/-10 = -4

The diagonal of the rectangle is 14.87 units.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Area of rectangle = 110 square units

Length = 11 units

Area of a rectangle = Length x Wide.

110 square units = Length x Wide

110 = 11 x Wide

Wide = 110/11

Wide = 10

Now,

The diagonal of a rectangle.

Using the Pythagorean theorem we get,

Diagonal² = Wide² + Length²

Diagonal² = 10² + 11²

Diagonal² = 100 + 121

Diagonal² = 221

Diagonal = √221
