Answer:
[tex]\frac{1}{9}[/tex] or 11.11%
Step-by-step explanation:
P(A) = probability of an event
f = favored outcomes
N = number of total outcomes
[tex]P(A)=\frac{f}{N}[/tex]
In this equation there is one favored income, when the first counter is blue and the second one is green. There are also nine total outcomes. This means that the equation necessary is:
[tex]P(A)=\frac{1}{9}[/tex]
The probability that Mike takes a blue counter and then Ellie takes a green counter is [tex]\frac{1}{9}[/tex] or around 11.11%

what does a correlation coefficient of 0 indicate?
It is crucial to note that a correlation coefficient of 0 does not imply that there is no link between the variables; rather, it indicates that the relationship is not linear.
What is correlation coefficient?A correlation coefficient is a statistical measure of the extent to which changes in one variable predict changes in another. The value of a positively linked variable rises or falls in lockstep. Correlation coefficients, in summary, are used to determine the strength and direction of linear correlations between pairs of variables. Pearson's correlation coefficient should be used when both variables are normally distributed; otherwise, Spearman's correlation coefficient should be used. Pearson's correlation coefficient is calculated by dividing the covariance of two variables by the product of their standard deviations.
Here,
A correlation value of 0 denotes that no linear relationship exists between two variables. It indicates that whether one variable rises or decreases, the other variable does not change. In other words, no relationship exists between the two variables.

D.) Draw a graph of this function, carefully labeling your intercepts and showing the end behavior.
A. The y-intercept is at the point (0, 0).
B. The zeros are x = 0 or x = ±√5
C.
How to solve the expressionA) The y-intercept of this graph is the point where x = 0.
When x = 0, the value of y
= 0^4 - 5*0^2
= 0.
Therefore, the y-intercept is at the point (0, 0).
B) The x-intercepts/roots of the function are the values of x that make y = 0.
To find these values, we need to set y = 0 and solve for x:
x⁴ - 5x² = 0
x⁴ = 5x²
x² = x⁴/5
x = ±√(x⁴/5)
We can simplify this expression by factoring x² out of both sides:
x²(x² - 5) = 0
x² = 0 or x² - 5 = 0
x = 0 or x = ±√5
hence the x-intercepts are at x = 0 and x = ±√5.
C) The end behavior of this function refers to how the graph of the function approaches the x-axis as x approaches positive infinity and negative infinity.

The median is the midpoint of the distribution. it is the number such that half of the observations fall above it, and half fall below it.
The following statement is correct.
The median M of a distribution is the number at which half of the observations are smaller and half are greater.
For skewed distributions or distributions containing outliers, the median is the most useful metric of central tendency. For example, in highly skewed income distributions, the median is frequently utilised as a measure of central tendency.
For normal distributions, the mean is employed. For skewed distributions, the median is typically utilised. The mean is not a reliable tool since it is heavily impacted by outliers. Because it is far more robust and comprehensible, the median is better suited for determining central tendency from skewed distributions.

The probability of selecting 4 defective calculators is 0.0009.
The probability of selecting 4 defective calculators out of a group containing 47 defective and 29 non-defective calculators can be calculated using the formula for a combination. The formula is n!/r!(n-r)! where n is the total number of items and r is the number of items being selected. In this case, n is 76 (47 defective + 29 non-defective) and r is 4. Therefore, the probability of selecting 4 defective calculators is 0.0009. To round this answer to four decimal places, the answer is 0.0009.
To calculate this answer, the first step is to calculate the total number of combinations that can be made using 4 items out of 76 items. This is calculated using the formula n!/r!(n-r)!. The numerator, n!, is equal to 76! which is equal to 5.43e+102. The denominator, r!(n-r)!, is equal to 4!(76-4)! which is equal to 5.90e+09.

jennifer has three more dimes than nickels and three times as many quarters as nickels. if she has $7.50, how many quarters does she have? www.wyzant
Jennifer has 48 nickels, which means she has 144 quarters.
Let's call the number of nickels Jennifer has "n".
Since Jennifer has three more dimes than nickels, she has n + 3 dimes.
And since she has three times as many quarters as nickels, she has 3n quarters.
We can start by figuring out the total value of the nickels and dimes in terms of cents:
n * 5 cents + (n + 3) * 10 cents = 750 cents
Expanding the right side of the equation and solving for n:
5n + 10n + 30 cents = 750 cents
15n + 30 cents = 750 cents
15n = 720 cents
n = 48
So Jennifer has 48 nickels, which means she has 3 * 48 = 144 quarters.

a boat is traveling east across a river that is 112 meters wide at 8 meters per second. If the river has a northeast current of 5 meters per second, what is the resultant speed of the motorboat rounded to the nearest tenth?
Resultant speed of the motorboat is 9.4 m/s.
What is Pythagorean Theorem?Pythagorean theorem states that the squared value of longest side in an right angle triangle will be equal to the addition of the squared value of two smaller sides. Thus, the resultant speed of the boat is 9.4 m/s
This is the concept of application of the pythagorean theorem.
The boat is traveling in the east direction at a speed of 8 m/s but the river has a northward current of 5 m/s. We know than both the directions (East and North) are perpendicular to each other. The bend tending toward east but the river slows down the speed and makes the boat tending toward north-east.
Thus, by applying Pythagorean theorem, the resultant speed can be calculated as:
c² = a² + b²
c² = 8² + 5²
c² = 64 + 25
c² = 89
c = [tex]\sqrt{89}[/tex]
c = 9.4 m/s
Hence, the resultant speed of boat is 9.4 m/s.

The Fréchet distance is a mathematical metric for comparing the similarity of curves that takes into account the position and arrangement of curve points. Maurice Fréchet is honored by having his name used. The pairs of points that make up the Fréchet distance sweep continuously along their respective curves, so the Fréchet metric takes the flow of the two curves into account. As a result, the Hausdorff distance and other similarity measures for arbitrary point sets are inferior to the Fréchet distance for curves. Two curves might have a small Hausdorff distance but a large Fréchet distance.

Find the surface area of each prism below
The surface area of a solid object is defined as the area that the object occupies. To find the surface area we must find the total area of its faces.
Here, we are given a triangular prism and we are asked to find its surface area.
How do we find the surface area of a triangular prism?We can find the area of a triangular prism using the following formula (as shown in the attached image, Please note that "b" and "s2" have the same defined length) :
(S + b + h)L + bh
Where
S = Slant length b = the length of the base H = height of triangle L = length of prismHere, we are given the length of the base(8in), the height(15in) and the length of the prism(21in); however we are not given the slant length. so we must find it.
Finding the slant lengthIf we ignore the prism itself and look at the base, we notice that the base is a right angled triangle. Within the triangle we have its base length and height and we need to find the hypotenuse. We can do so by using the Pythagorean theorem: a² + b² = c² where a and b = length of legs and c = hypotenuse.
Here a and b = 15 and 8.
By plugging in these values we acquire:
==> 15² + 8² = c²
==> 225 + 64 = c²
==> 289 = c²
==> 17 = c
So the hypotenuse (or slant length) = 17
Finding the surface areaNow that we have identified all the variables we can finally plug in the values to get the surface area.
We have
S = 17b = 8h = 15L = 21Plugging this into (S + b + h)L + bh, we acquire
==> (17 + 8 + 15)21 + 8(15)
==> 40(21) + 8(15)
==> 840 + 8(15)
==> 840 + 120
==> 960
The surface area is 960 in²

A line has a slope of – 9 and includes the points ( – 9,1) and ( – 10,q). What is the value of q?
To find the value of q, we can use the point-slope form of a line:
y - y1 = m(x - x1)
where m is the slope of the line, (x1, y1) is a point on the line, and (x, y) is a second point on the line.
In this case, we have the slope of the line as -9 and the point ( -9, 1), so we can plug in the values:
y - 1 = -9 (x - (-9))
Expanding and solving for y, we get:
y = -9x + 90
Next, we want to find the value of y when x = -10. Substituting this value into the equation:
q = -9(-10) + 90
Solving for q:
q = -90 + 90 = 0
So, the value of q is 0.
