What is proportion?Numerous challenges in daily life can be solved with proportion, including those in business when handling transactions or in the kitchen, among other situations. It creates a connection between two or more values, making it easier to compare them. In the actual world, ratios and proportions are used by individuals in a variety of settings and contexts. To manage finances and shop, one uses ratios and proportions. Additionally, they are employed in value comparison. When two variables' ratios are equivalent, proportional relationships between them emerge. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value.To learn more about proportion refers to:

ANSWER EITHER 1 OR BOTH PARTS
Answer:
140 for both
Step-by-step explanation:
An exterior angle and its adjacent interior angle are supplementary angles, so they add to 180°.
so Part A = 180-40=140
Part B
The exterior angle theorem states that: The measure of an exterior angle of a triangle is supplementary to its adjacent interior angle. The sum of the remote interior angles must equal the measure of the exterior angle of the triangle.
It's also 140
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.

Step-by-step explanation:
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.

the uniform probability distribution is used with . a. a discrete random variable b. any random variable c. a normally distributed random variable d. a continuous random variable
The uniform probability distribution is used with option (d) a continuous random variable.
The uniform probability distribution is used for a continuous random variable, meaning that a variable can take on any value within a specified range, and the likelihood of any value within that range is equal. This distribution is often represented by a rectangle with height equal to the uniform probability density, and width equal to the range of the variable. In other words, if the range of a continuous random variable is from a to b, and we define the uniform distribution over this range, then the probability of any value between a and b is equal to (b-a)^-1. The uniform distribution is useful in various applications where the lack of knowledge of the underlying process leads to equal probabilities for all outcomes in a given range.

the distance between the two curves changes for 0
The distance between the two curves, with respect to the curves changing can be calculated as follows:
3-(3-2sin(2θ))
[tex] \frac{dx}{dθ} 2 \sin(20) [/tex]
2cos(20)
4cos(20)
[tex]4 \cos(2 \frac{\pi}{3} ) = - 2[/tex]
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.

Justin used average two rolls of ribbon in total, using 1/5 of one and 2/5 of another.
Justin had 3 rolls of ribbon before he started tying parcels and presents. He used 1/5 of a roll of ribbon to tie a parcel, and then used 2/5 of another roll of ribbon to tie a present. This means that he used two rolls of ribbon in total, with 1/5 of one and 2/5 of the other. He still has one roll of ribbon remaining, meaning that he didn't use all three rolls of ribbon. To calculate the total amount used, you would need to multiply 1/5 and 2/5 by the length of the ribbon, or alternatively multiply the two fractions together to get 2/5 of a roll of ribbon used. This means that he used two rolls of ribbon in total, with 1/5 of one and 2/5 of the other.

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 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.

If Sam and Tyrone are running on a trail. Sam reaches the 4th mile marker at the same time that Tyrone reaches the 1st mile marker. The number of minutes that Sam and Tyrone meet is: B) 45 minutes .
How to find the number of minutes?Speed = Distance/Time
Sam speed = 1/10 mile/minute

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.

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. By dividing the numerator by the denominator, the probability of selecting 4 defective calculators is 0.0009. To round this answer to four decimal places, the answer is 0.0009.

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.
