Step-by-step explanation:

to find percentages:

\(\frac{part}{whole}\) I \(\frac{percent}{100}\)     pretend this is a box

basically just fill this in and it will give you what you want. For example, here, you have the original and part of the original so it will look like this:

\(\frac{99}{180}\) I \(\frac{x}{100}\) then you multiply across and divide top to bottom (doesn't matter in which order), so: \(\frac{99}{180}\) =0.55 · 100 = 55%.

Answer:

5 un^2

Step-by-step explanation:

the liens from (0, 0) to (1, 3) and (1, 3) to (4, 2) are perpendicular meaning that the angle at (1, 3) is a right angle

to find the lengths of the sides we must use the pythagorean theorem

a^2 + b^2 = c^2

for the leftmost side

we have 1^2 + 3^2 = c^2

1 + 9 = 10

c^2 = 10

c = sqrt(10)

for the top side

we have

the same thing

1^2 + 3^2 = c^2

1 + 9 = 10

c^2 = 10

c = sqrt(10)

you must multiple sqrt(10) by sqrt(10) and then by 1/2

sqrt(10) * sqrt(10) is 10

10 * 1/2 is 5

the area is 5 un^2

The angles 95° and 60° are neither adjacent nor vertical angles.

The angles 70° and 60° are adjacent angles.

The angles 95° and 60° are neither adjacent nor vertical angles. Adjacent angles are angles that share a common vertex and a common side. Vertical angles are a pair of non-adjacent angles formed by two intersecting lines. In this case, the angles 95° and 60° do not meet the criteria for being adjacent or vertical angles as they do not share a common vertex or a common side, nor are they formed by intersecting lines.

The angles 70° and 60° are adjacent angles. Adjacent angles are angles that share a common vertex and a common side. In this case, the angles 70° and 60° share the common vertex at the point where the sides intersect and also share the common side formed by the intersection of the lines. Therefore, the angles 70° and 60° are adjacent angles.

No, this mechanism does not satisfy Dominant Strategy Incentive Compatibility (DSIC) no matter which random ordering is chosen by the mechanism.

DSIC requires that each agent has a dominant strategy, meaning that regardless of what other agents do, it is always in an agent's best interest to report their true preferences.

In this mechanism, the problem lies in the step where the ith agent is assigned her favorite room from the set R.

Since the rooms are assigned based on the agent's preferences, an agent has an incentive to misreport her preferences in order to increase her chances of getting her most preferred room.

For example, if an agent knows that her most preferred room is more likely to be available at a later stage, she may strategically misreport her preferences to increase the likelihood of getting that room.

This introduces the possibility of manipulation and strategic behavior, which violates the DSIC property.

Therefore, the mechanism described does not satisfy DSIC, regardless of the chosen random ordering.

Given that 5 is a factor of 10, any number that can be divided by 10 is likewise divisible by 5.

In mathematics, the term "divisibility" indicates a number's tendency to be divided by another number in an equal amount without any residue. For instance, it's simple to understand how 40 by 4 can be divided. A huge piece of land that can be divided into smaller chunks and sold separately is said to be divisible, much as it is obvious when you cut into a pan of brownies and distribute equal amounts to each of your friends.  

Step-by-step explanation:

Given :

Statement  'The relationship between numbers divisible by 5 and 10'.

Find the statement that BEST clarifies the statement in question?

Solution :

First we study the divisibility rules,

The only two possible outcomes for a number that is divisible by five are five or zero.

As the prime factors of 10 are 5 and 2, the rule for a number to be divisible by 10 is that it must be even and divisible by 5, and the last digit must be a 0.

Because 5 is a factor of 10, the accurate statement that describes the link between numbers divisible by 5 and 10 is that a number that is divisible by 10 is likewise divisible by 5.

Answer:

a) answer is "a"

b) answer is "-2b"

c) answer is "-c"

d) answer is "3c"

Step-by-step explanation:

Absolute value is positive value of something.

a>0 then a must be positive so absolute value means nothing if a is already positive. Therefore answer is a.

b<0, so b must be negative. absolute value makes 2b positive but you know b is negative so answer is -2b.

c<0 same as a except sign is flipped so answer is negative instead of positive.

c>=0, C is either 0 or positive so absolute value does nothing yet again so answer is just 3c.

Sorry is explanation wasn't through i'm only in middle school

a. | a | > 0, a is greater than and less than zero.

b. | 2b | if b < 0, b is not less than zero not greater than zero.

c. | c | if c < 0, c is not less than zero not greater than zero.

d.  | 3c | if c ≥ 0, c is greater than zero and less than zero.

We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.

In piecewise terms  | x | = x for x ≥ 0 and | x | = - x for x < 0.

Given,

We have proved that AB = CD in the given trapezoid ABCD using the properties of the trapezoid and the circle.

To prove that AB = CD, we will use several properties of the given trapezoid and the circle. Let's start by analyzing the information provided step by step.

AC is the bisector of angle BAD:

This implies that angles BAC and CAD are congruent, denoting them as α.

M is the midpoint of CD:

This means that MC = MD.

The circumcircle of triangle OMD intersects AC again at point K:

Let's denote the center of the circumcircle as P. Since P lies on the perpendicular bisector of segment OM (as it is the center of the circumcircle), we have PM = PO.

BK ⊥ AC:

This states that BK is perpendicular to AC, meaning that angle BKC is a right angle.

Now, let's proceed with the proof:

ΔABK ≅ ΔCDK (By ASA congruence)

We need to prove that ΔABK and ΔCDK are congruent. By construction, we know that BK = DK (as K lies on the perpendicular bisector of CD). Additionally, we have angle ABK = angle CDK (both are right angles due to BK ⊥ AC). Therefore, we can conclude that side AB is congruent to side CD.

Proving that ΔABC and ΔCDA are congruent (By SAS congruence)

We need to prove that ΔABC and ΔCDA are congruent. By construction, we know that AC is common to both triangles. Also, we have AB = CD (from Step 1). Now, we need to prove that angle BAC = angle CDA.

Since AC is the bisector of angle BAD, we have angle BAC = angle CAD (as denoted by α in Step 1). Similarly, we can infer that angle CDA = angle CAD. Therefore, angle BAC = angle CDA.

Finally, we have ΔABC ≅ ΔCDA, which implies that AB = CD.

Proving that AB || CD

Since ΔABC and ΔCDA are congruent (from Step 2), we can conclude that AB || CD (as corresponding sides of congruent triangles are parallel).

Thus, we have proved that AB = CD in the given trapezoid ABCD using the properties of the trapezoid and the circle.

0.003 is the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations

To calculate the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations.The mean is the expected number of calls involving a fax transmission, while the standard deviation is the measure of variability in the distribution. We then use this information to calculate the probability of exceeding the expected number by more than 2 standard deviations, which can be done using the z-score formula. The z-score for values more than 2 standard deviations away from the mean is 2.33, which corresponds to a probability of 0.003. Thus, the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations is 0.003.

The cost of making the chest with these dimensions is approximately $3.83.

Let's start by finding an expression for the cost of making the chest in terms of its dimensions. The cost of the oak top and sides is given by:

cost of oak = 2lw + 2lh

where l is the length and w is the width of the chest, and h is the height (which we don't know yet). The cost of the pine bottom is given by:

cost of pine = lw

The total cost of making the chest is the sum of these two costs:

total cost = cost of oak + cost of pine

= 2lw + 2lh + lw

We want to minimize this cost subject to the constraint that the volume of the chest is 0.25 cubic metres. The volume of a rectangular box is given by:

volume = length × width × height

= lwh

Since the volume is given as 0.25 cubic metres, we have:

lwh = 0.25

We also know that the length is twice the width, so we can write:

l = 2w

Substituting this into the expression for volume, we get:

\(2w^{2h} = 0.25\)

Solving for h, we get:

\(h = 0.125/w^2\)

Substituting this expression for h into the expression for the total cost, we get:

total cost = \(2lw + 2(0.125/w^2)w + lw\)

= 2lw + 0.25/w

To minimize this cost, we can take the derivative with respect to w and set it equal to zero:

d(total cost)/dw =\(2l - 0.25/w^2 = 0\)

Solving for w, we get:

w = \(\sqrt{0.125/l)}\)

Substituting this value for w back into the expression for h, we get:

h = \(0.125/w^2 = 8l\)

Therefore, the dimensions that will minimize the cost of making the chest are:

length = 2w = \(2\sqrt{(0.125/l)}\)

width = w =\(\sqrt{0.125/l)}\)

height = h = 8

To find the cost of making the chest, we can substitute these values into the expression for the total cost:

total cost = 2lw + 0.25/w

= \(2\sqrt{(0.125/l} ) \times \sqrt{0.125/l)} \times 2 + 0.25/\sqrt{(0.125/l)}\)

= 4 × 0.125 + 0.25 × sqrt(l/0.125)

= 0.5 + 2\(\sqrt{2\) ≈ 3.83

Therefore, the cost of making the chest with these dimensions is approximately $3.83.
