solve the proportion 15/6 = 10/p
Answer:
p = 4
Step-by-step explanation:
The usually recommended procedure for solving a proportion is to "cross multiply", then divide by the coefficient of the variable. (Solve the remaining one-step equation.)
Cross multiplyThis means multiply both sides of the equation by the product of the denominators:
(15/6)(6p) = (10/p)(6p) . . . . "cross multiply"
15p = 60 . . . . . . simplify
Second stepNow, divide by the coefficient of the variable.
15p/15 = 60/15
p = 4
The solution is p = 4.
__
Additional comment
If the variable is in the numerator of the proportion, using cross multiplication, you will find that you end up multiplying and dividing by the other denominator. To solve it in that case, you only need to multiply by the denominator under the variable.
__
For example, to solve ...
2/5 = p/10
you only need to multiply by 10. You don't need to multiply by 50, then divide by 5.
__
Any proportion can be written 4 ways:
\(\dfrac{a}{b}=\dfrac{c}{d}\ \Leftrightarrow\ \dfrac{a}{c}=\dfrac{b}{d}\ \Leftrightarrow\ \dfrac{b}{a}=\dfrac{d}{c}\ \Leftrightarrow\ \dfrac{c}{a}=\dfrac{d}{b}\)
This suggests another strategy: invert the whole proportion, then solve it as one with p in the numerator:
6/15 = p/10 ⇒ p = 10(6/15) = 4
Multiply the numerator of one fraction to the denominator of other and denominator of the first term to the numerator of another term is cross multiplication. For given proportion 15/6 = 10/p. The value of P is 4.
What is a cross multiplication method?Multiply the numerator of one fraction to the denominator of other and denominator of the first term to the numerator of another term
The given proportion is 15/6 = 10/p.
We need to find the value of p.
15/6 = 10/p
Use cross multiplication method.
15p=6*10
15p=60
p=4
Therefore the value of p is 4 in equation 15/6 = 10/p obtained by using cross multiplication.

a. There does exist such a function.
b. There does not exist such a function.
There does not exist such a function.
This is because if f = x2yz - e2x2, then the partial derivative of f with respect to y would be x2z, while the partial derivative of f with respect to y in the second equation is 2xz - e2xy27. These two expressions are not equal, which means there is no function that satisfies both equations simultaneously. Therefore, there does not exist such a function.

The value of the constant term in the expansion of (\(x^{2}\) +1/\(x^3\)\()^1^0\)is: C. 252.
What is the constant term?The constant term of (\(x^{2}\) +1/\(x^{3} )^1^0\)is:
\(C(10, r) * (x^2)^(^1^0^-^r^) * (1/x^{3} )^r\)
where:
C(10, r) = binomial coefficient for choosing r terms out of 10
\((x^2)^(^1^0-^r^)\)and (1/\(x^{3})^r\) = powers of x in each term.
Let find the value of r such that the powers of x cancel out.
when r = 5
\((x^{2} )^(10-r)\) * (1/\(x^{3} )^r\)
=\(x^{2} ^(20-5)\times x^(-3r)\)
=\(x^{5} \times x^(-15)\)
= 1
Constant term is:
\(C(10, 5) * (x^2)^(10-5) * (1/x^3)^5\)
=\(C(10, 5) * x^1^0 * 1/x^1^5\)
= \(252 * 1/x^5\)

In an island population, the frequencies of the three MN blood types are given here: M: 550; MN: 725; N: 225. Determine chi-square value (to nearest hundredth) to test the hypothesis that mating is random for this population.
The chi-square value to test the hypothesis of random mating is 0.
To determine the chi-square value for testing the hypothesis of random mating in this population, we need to compare the observed frequencies of the blood types (M, MN, N) with the expected frequencies under the assumption of random mating.
First, we calculate the expected frequencies. Assuming random mating, the expected frequency for each blood type can be calculated by multiplying the total population size by the expected proportions for each blood type. The expected proportions can be obtained by dividing the total count for each blood type by the sum of all counts.
Total count: 550 + 725 + 225 = 1500
Expected proportions:
M: 550 / 1500 = 0.3667
MN: 725 / 1500 = 0.4833
N: 225 / 1500 = 0.1500
Expected frequencies:
M: 0.3667 * 1500 = 550
MN: 0.4833 * 1500 = 725
N: 0.1500 * 1500 = 225
Now we can calculate the chi-square value using the formula:
chi-square = Σ((observed frequency - expected frequency)^2 / expected frequency)
Calculating for each blood type:
For M: ((550 - 550)^2 / 550) = 0
For MN: ((725 - 725)^2 / 725) = 0
For N: ((225 - 225)^2 / 225) = 0
Summing the individual chi-square values: 0 + 0 + 0 = 0
The chi-square value is 0 (to the nearest hundredth) when testing the hypothesis of random mating in this population.

What are the coordinates of a point?
Coordinates are a pair of integers (Cartesian coordinates), or sporadically a letter and a number, that identify a certain place on a grid, also referred to as a coordinate plane. The x-axis (horizontal) and y-axis are the two axes that make up a coordinate plane (vertical).
Given that the location of the entrance is at (6,5).
To reach the waterfall, you need to go 3 km to the left and 4 km down from the park entrance.
The x-coordinate decreases to the left side of a point and increases to the right side of a point.
The y-coordinate decreases to a downward point and increases upward a point.

2. a statement contradicting the claim in the null hypothesis is classified as the alternative hypothesis.
The alternative hypothesis is a statement that contradicts the claim made in the null hypothesis.
Is the alternative hypothesis a statement that opposes the null hypothesis?The alternative hypothesis is a fundamental concept in hypothesis testing. In this statistical framework, the null hypothesis represents the default assumption or claim about a population parameter.
The alternative hypothesis, on the other hand, contradicts the null hypothesis and proposes an alternative explanation or claim.
When conducting a hypothesis test, we collect data and analyze it to determine whether the evidence supports rejecting the null hypothesis in favor of the alternative hypothesis.
The alternative hypothesis is typically what the researcher is trying to establish or prove.
It is important to note that the alternative hypothesis does not necessarily specify a specific alternative value or hypothesis.
It simply states that there is a difference or relationship between variables, contrary to the null hypothesis.
The specific form of the alternative hypothesis depends on the research question and the nature of the investigation.

Which equation matches the table?
An equation that matches the table include the following: y = x + 5.
How to determine an equation of this line?In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):
y - y₁ = m(x - x₁)
Where:
m represent the slope.x and y represent the points.First of all, we would determine the slope of this line;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (6 - 5)/(1 - 0)
Slope (m) = 1/1
Slope (m) = 1.
At data point (0, 5) and a slope of 1/, a linear equation in slope-intercept form for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - 5 = 1(x - 0)

g etween two variables may be explained away by the presence of another variable that accounts for the original correlation. These relationships are known as
A spurious correlation is a correlation between two variables that appears to be causally linked but is actually due to the influence of a third variable that is not considered. The correct answer is spurious correlation.
Spurious correlations are correlations that exist between two variables, but they are not actually causally related to one another, despite the fact that they appear to be causally related at first glance. The relationship between two variables may be accounted for by a third variable that was previously overlooked or not considered, causing the original correlation to be explained away. Spurious correlations are commonly found in science and research, and they can lead to misleading results if not properly identified and accounted for. It is critical to account for all potential confounding variables in order to establish causal links between variables and avoid spurious correlations. Therefore, researchers must carefully consider all variables that might influence the relationship between two variables to avoid drawing inaccurate conclusions.

the probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring. true/false
The given statement "the probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring." is False.
The union of two events A and B represents the event that at least one of the events A or B occurs. The probability of the union of two events can be calculated using the formula:
P(A or B) = P(A) + P(B) - P(A and B)
On the other hand, the intersection of two events A and B represents the event that both events A and B occur. The probability of the intersection of two events can be calculated using the formula:
P(A and B) = P(A) * P(B|A)
where P(B|A) is the conditional probability of B given that A has occurred.
It is possible for the probability of the union of two events to be greater than the probability of the intersection of two events if the two events are not mutually exclusive.
In this case, the probability of both events occurring together (the intersection) may be relatively small, while the probability of at least one of the events occurring (the union) may be relatively high.
In summary, the probability of the union of two events occurring can sometimes be greater than the probability of the intersection of two events occurring, depending on the relationship between the events.
