if n decreases then the value of level of significance of each samples \(\alpha\) decreases

1. Critical Value: The value of the statistic for which the test just rejects the null hypothesis at the given significance level.

2. Power of the Test: The probability that the test correctly rejects the null hypothesis when the alternative is true.

3. Significance Level: The prescribed rejection probability of a statistical hypothesis test when the null hypothesis is true.

4. Size of the test: The probability that the test incorrectly rejects the null hypothesis when it is true.

if n decreases then the value of level of significance of each samples \(\alpha\) decreases and hence 1- \(\alpha\) increases which are called the rejection of test sample increases

The general solution for the differential equation is y(t) = e^(-0.5t)(C1*cos(2.5t) + C2*sin(2.5t)), where C1 and C2 are constants.

The general solution for a differential equation with complex roots can be found using the auxiliary equation.

For the first differential equation, y" - 10y' +29y = 0, the auxiliary equation is r^2 - 10r + 29 = 0. Using the quadratic formula, we can find the complex roots of the auxiliary equation:

r = (-(-10) ± √((-10)^2 - 4(29)(1)))/(2(1))
r = (10 ± √(-16))/2
r = (10 ± 4i)/2
r = 5 ± 2i

The general solution for the differential equation is y(t) = e^(5t)(C1*cos(2t) + C2*sin(2t)), where C1 and C2 are constants.

For the second differential equation, 6y" - 6y' + 75y = 0, the auxiliary equation is 6r^2 - 6r + 75 = 0. Using the quadratic formula, we can find the complex roots of the auxiliary equation:

r = (-(6) ± √((6)^2 - 4(6)(75)))/(2(6))
r = (-6 ± √(-1800))/12
r = (-6 ± 30i)/12
r = -0.5 ± 2.5i

Answer:

If two points pass through each other it means that it is not a function. The vertical line test shown proves that fact.

Step-by-step explanation:

Step-by-step explanation:

x^2+4x=0

therefore x=-4

One lily is $9

One shrub is $11

Step-by-step explanation:

Let the lillies be x

Let the shrub be y

2x + 6y= 84.........i

6x + 6y = 120..........ii

Lets make x the subject formula in eq(I)

2x= 84- 6y

x = 42 - 3y........iii

Put the value of x into eq (ii)

6(42-3y) + 6y = 120

252 - 18y + 6y= 120

252 - 12y= 120

12y= 252-120

12y= 132

Y= 11

Put the value of Y into eq (I)

2x + 6(11)= 84

2x + 66= 84

2x= 18

X= 9

Therefore,the cost of one day lily is $9 and the cost of one shrub is $11.

The correct answer is wxy*z/+. Among all of them this is the postfix expression.

Post-fix expressions are a type of mathematical operation in which the operator is placed after the operands, rather than before them, as is the case with the more common infix notation. This type of expression is also known as Reverse Polish Notation (RPN).

For example, consider the expression: 3 + 4. Written in infix notation, this would be written as 3 + 4. In postfix notation, this would be written as 3 4 +. The expression is read from left to right, starting with the operands (3 and 4 in this example). The operator (+ in this case) is applied to the two operands after they have been read.

To solve for x, the value of x is 40^o.

When two given lines intersect at a point, a series of angles which have common properties called vertical opposite angles are formed.

Two lines are perpendicular if and only if they are at right angle to each other.

To solve for x in the given question, lines AB is perpendicular to CD Let the point of intersection of AB and CD be labelled as O.

Given that: AB ⊥ CD, then;

m<AOD = m<BOC            (vertically opposite angle theorem)

But, m<BOC = 90^o

So that,

(2x + 10) = 90^o

2x = 90 - 10

    = 80

x = 80/ 2

  = 40

x = 40^o

Therefore after solving, it can be deduced that the value of x is 40^o.

If UV≅PM then UV≅PM → Definition of congruence, EF≅EF → Reflexive property of congruence, If AB≅LM and LM≅ST then AB≅ST  → Transitive property of congruence.

A statement that is accepted as true without evidence, also referred to as an axiom. Lemmas and theorems are deduced from postulates, which serve as their fundamental building block. For instance, Euclid's postulates, a set of five postulates, provide the foundation of all of Euclidean geometry.

A) If and only if two segments have equal amounts of each, they are congruent.

If UV≅PM then UV≅PM → Definition of congruence

B) An angle, line segment, or shape is always congruent to itself, according to the reflexive characteristic of congruence in geometry.

EF≅EF → Reflexive property of congruence

C) According to the transitive characteristic of congruence, "all sides are congruent to each other if two sides are congruent to the third side."

If AB≅LM and LM≅ST then AB≅ST  → Transitive property of congruence

D) Actually fairly straightforward, equality has the symmetric condition. According to this criterion, if a = b, then b must also be a. In other words, even if two equations' sides are switched, the equation still makes sense.

If AB=XY then XY =AB  → Symmetric property of equality

E) The additive property of equality in an equation asserts that the sides stay equal whether we add or subtract the same amount from both sides of the equation. For entire numbers as well, this property is valid.

If 2x-3=13 then 2x=16 → Addition property of equality

Add 3 on both the sides of equation we get

2x-3+3=13+3

⇒ 2x=16

Therefore, the statement If 2x-3=13 then 2x=16 follows addition property of equality.

Option A. If the alternative hypothesis of the test had been lower-tailed instead of two-tailed, the conclusion of the test would be different.

Recall that a two-tailed test is used when the alternative hypothesis is that the population parameter is different from the null hypothesis value in any direction, while a lower-tailed test is used when the alternative hypothesis is that the population parameter is less than the null hypothesis value.

In the given scenario, if the alternative hypothesis of the test had been lower-tailed instead of two-tailed, we would have tested the following null and alternative hypotheses:

H0: Pharaoh's translation is not worse than the other software's translation.

Ha: Pharaoh's translation is better than the other software's translation.

In this case, we would have calculated the p-value for the lower tail of the sampling distribution, and compared it to the significance level alpha. If the p-value is less than alpha, we would reject the null hypothesis and conclude that Pharaoh's translation is better than the other software's translation. If the p-value is greater than alpha, we would fail to reject the null hypothesis and conclude that there is not enough evidence to suggest that Pharaoh's translation is better than the other software's translation.

Therefore, the correct answer to the question is option A: Unlike the two-tailed test, we would conclude that there is a difference between Pharaoh's translation and the translation of the other software.

Using integer addition, the total profit from the Spanish Club's bake sale is $270.

Integer refers to whole numbers(non-fractional numbers) that can either be positive or negative, and zero.

Adding positive integers will result to a positive integer while adding negative integers will result to a negative integer. But, adding a negative integer to a positive integer is the same as subtracting its positive.

If the income from the Spanish Club's bake sale was $300 and the expenses for the sale is $30, the total profit will be:

income = +$300

expenses = -$30

Using integer addition,

profit = income + expenses

profit = +$300 + (-$30)

profit = $300 - $30

To be 95% positive that the population proportion is within 0.02 percentage points, we would need to survey at least 2,450 drivers.

To determine the minimum sample size needed to estimate a population proportion with a certain level of confidence and a given margin of error, we use the following formula:

n = [Z² * p * (1-p)] / E²

where:

- n is the sample size

- Z is the Z-score corresponding to the desired level of confidence

- p is the estimated population proportion

- E is the desired margin of error

Assuming we do not have any prior information about the population proportion, we can use a conservative estimate of 0.5 for p, which maximizes the sample size needed. Also, for a 95% confidence level, the Z-score is approximately 1.96.

Plugging in the values, we get:

n = [1.96² * 0.5 * (1-0.5)] / 0.02²

n = 2.45 * 10³

Rounding up to the nearest whole number, we get:

n = 2,450

Therefore, we would need to survey at least 2,450 drivers to be 95% confident that the population proportion is estimated to within 0.02.

So the equation of this circle is

(x - 4)² + (y - 4)² = 29

The side lengt of the square is approximately 1839 feet.

To find the length in feet of the side of a square with an area of 1.00 acre, we need to convert the acreage to square feet.

Given:

1 acre = 640 acres/mile² (640 acres in a square mile)

1 mile = 5280 feet (conversion factor from miles to feet)

To convert acres to square feet, we can multiply by the conversion factor:

1 acre = 640 acres/mile² * 1 mile² * 5280 feet

Simplifying the units:

1 acre = 640 * 5280 square feet

Now, to find the length of the side of the square, we can take the square root of the area:

Side length = √(1 acre * 640 * 5280 square feet)

Calculating:

Side length ≈ √(1 * 640 * 5280) ≈ √3379200 ≈ 1839.29 feet
