Compared to the distance between Earth and Mars, the distance between Jupiter and Saturn is much larger. (Option B)
Planetary distance is the measure of distance between two planets which vary based on the placement of the planet in an orbit. An orbit is the path where planets revolve around the Sun in the solar system. The planets’ orbits form an elliptical shape. To measure the distance between two planets in the solar system an astronomical measure used is astronomical unit (AU). An Astronomical Unit (AU) is the average distance between Earth and the Sun and is used to measure distances within our solar system. The distance between Mars from Earth is equivalent to 0.52 AU while the distance between Jupiter and Saturn is 4.32 AU.

What is the mean deviation method?.
The step-by-step method of mean deviation given below.
What is the mean deviation method?
When calculating the average departure from the mean value of a particular data set, statisticians employ a measure known as the mean deviation. Following the steps below will make it simple to determine the mean deviation of the data values.
In statistics, the term "deviation" refers to the discrepancy between the observed value of a data point and its expected value. As a result, mean deviation, also known as mean absolute deviation, is the typical departure of a data point from the mean, median, or mode of the data collection.
MAD = (∑ f1 |xi - x⁻|) / ∑ f1
fi is the frequency of repetition xi, xi of denotes the mid-value of the class interval.
Example, Say your data set is: 9, 2, 5, 4, 12, 7, 8, 11, 9, 3, 7, 4, 12, 5, 4, 10, 9, 6, 9, 4.
The Mean is: 9 + 2 + 5 + 4 + 12 + 7 + 8 + 11 + 9 + 3 + 7 + 4 + 12 + 5 + 4 + 10+ 9 + 6 + 9 + 4. Over 20. That equals 104 over 20 = 7.
Statistics refers to deviation as the difference between the observed value of a data point and the expected value.

The mean and standard deviation of the number of people with blood type a-positive in 100 randomly selected is μ=85, σ=3.5707
What is meant by standard deviation?The standard deviation is a statistic that measures the amount of variation or dispersion of a group of values.
Standard deviation is usually abbreviated SD and is most commonly represented in mathematical texts and equations by the lower case Greek letter (sigma) for population standard deviation or the Latin letter s for sample standard deviation.
A low standard deviation indicates that the values are close to the mean of the set (also known as the expected value), whereas a high standard deviation indicates that the values are spread out over a broader range.
Given, The population proportion of success is p=0.85
And also given that the sample size is n=100
b) The population mean is:
μ=np
μ=100(0.85)
μ=85
Therefore, mean=85
And the population standard deviation is:
σ=√np(1-p)
σ=√100(0.85)(1-0.85)
σ=3.5707

Which graph best represents the distance, y, in miles, traveled by Amy for a certain amount of time, x, in hours?
Answer: B
Step-by-step explanation: We know that Amy took three hours to get to the hilltop, so A and D are out because they are saying she reached the hilltop in 2 hours, instead of 3. Then we have C and B left. The difference between them is that C is saying that they had a picnic for 4 hours instead of 5.
hope this helps!
please give brainliest!
Answer:
B
Step-by-step explanation:
The given graphs are distance-time graphs, where:
Time is on the x-axis.Distance is on the y-axis.As Amy walks from her tent to a hilltop in 3 hours, the first part of the graph should be a straight line with a positive gradient, where the x-values of its endpoints are:
x = 0 and x = 3.Therefore, we can immediately discount answer options A and D as they suggest that this part of Amy's journey takes only 2 hours.
Amy stops and has a picnic at the top of the hilltop for 5 hours. Therefore, her distance from the tent during this time does not change as she is not moving. This will be represented on the graph by a horizontal line that has endpoints at:
x = 3 and x = 8.Therefore, the graph that displays the given parameters is graph B.

in the fixed effects regression model, you should always exclude one of the binary variables for the entities independent of whether an intercept is present in the equation or not.
To avoid any perfect multicollinearity we need to exclude any one of the binary class variables for all the entities which are independent of whether an given intercept is present across the given equation or not.
Fixed outcomes is a statistical regression version wherein the intercept of the regression version is authorized to differ freely throughout people or groups. It is frequently implemented to panel information with the intention to manage for any individual-unique attributes that don't range throughout time. Use fixed-outcomes (FE) each time you're most effective inquisitive about reading the effect of variables that fluctuate over time.

Using the Dominant strategy and Nash equilibrium, helps you to choose a number between large sample (0-100) such that the choosing number is 2/3 of average guess of all and become a winner.
Dominant Strategy:
A dominant strategy refers to a player's preference for a particular choice of action, independent of the actions and decisions of other players in a strategy game. A dominant strategy is based on the playoffs the player wins.
The concept of Nash Equilibrium is not too difficult to understand. Imagine any combination of player choices. For example, everyone picks 34 in the hope that it matches her 2/3rds of other people's guesses. Nash proved that every game has at least one such equilibrium if randomized strategies are allowed.
Zeroth order - If everyone was a zero-order thinker, just guess randomly between 0 and 100 and pick a random number. Average = ( 0 + 100 ) / 2 = 50.
1st order thinkers guess 2/3 of 0th order thinkers = (2 / 3) × 50 = 33.

The number of victories is x.Its number of trials is n.P represents the likelihood that a trial will be successful.In this issue:
Three dices are made, hence n is equal to 3.
Since one of its six sides is a five, therefore, p = 1/6 = 0.1167.
P(X = 1) is the chance that the number five appears exactly once, so;
P(X = x) = C(n,x).pˣ.(1 - p)ⁿ⁻ˣ
P(X = 1) = C(3,1).0.1167¹.(0.8333)³
P(X = 1) = 0.3472
Thus, the probability that it appears five times exactly is 0.3472, or 34.72%.

The expression -2x³ + 13x² + 3x + 50 is equivalent to 10 - (2x³ + 11x² - 2x - 35) + (x + 5) + 6(4x²
Equivalent ExpressionAn algebraic expression is an expression which consists of variables, coefficients, constants, and mathematical operators such as addition, subtraction, multiplication and division. Generally, if two things are the same, then it is called equivalent. Similarly, in mathematics, the equivalent expressions are the expressions that are the same, even though the expression looks different. But if the values are plugged in the expression, both the expressions give the same result.
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
In the given expression;
10 - (2x³ + 11x² - 2x - 35) + (x + 5) + 6(4x²); this can be reduced or simplified to -2x³ + 13x² + 3x + 50
