The first special right triangle with angle 45° has the adjacent side equal to 16. The second special right triangle has the third angle equal to 60°, and the opposite and adjacent sides equal to 5 and 5√3 respectively, using the trigonometric ratios of sine and cosine.

The trigonometric ratios involves the relationship of an angle of a right-angled triangle to ratios of two side lengths. Basic trigonometric ratios includes; sine cosine and tangent.

cos45 = adjacent/8√2 {adjacent/hypotenuse}

recall cos45 = √2

so;

adjacent = √2 × 8√2 {cross multiplication}

adjacent = 8 × 2

adjacent side = 16

The third angle for the second right triangle is derived as;

180° - (30 + 90)° = 60°

considering the angle 30°;

sin30 = opposite/10

recall sin30° = 1/2

opposite = 10/2 {cross multiplication}

opposite side = 5

cos30 = adjacent/10 {adjacent/hypotenuse}

recall cos30 = √3/2

adjacent = 10 × √3/2 {cross multiplication}

adjacent side = 5√3

Therefore, the first special right triangle with angle 45° has the adjacent side equal to 16. The second special right triangle has the third angle equal to 60°, and the opposite and adjacent sides equal to 5 and 5√3 respectively, using the trigonometric ratios of sine and cosine.

How much water supporting the hydrostatic skeleton and the constriction of round muscles.

Hydrostatic skeletons (some of the time recently called "hydrostats") utilize a depression loaded up with water; the water is incompressible, so the organic entity can utilize it to apply power or change shape. Plants utilize osmotic pressure to compress the pit, while creatures do it with muscle layers in the hydrostat's walls.

The most widely recognized muscle game plan is to have a layer with longwise or longitudinal filaments and a layer with roundabout or circumferential strands.

Most hydrostatic skeletons are pretty much tube shaped, so longitudinal muscles will more often than not abbreviate them and furthermore enlarge them because of consistent volume, though circumferential muscles will generally do the inverse. The longitudinal and circumferential muscles are in this manner antagonistic.

290 people Apple wants to visit the store every day after Layla’s marketing campaign.

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Both linear equations with one variable and those with two variables exist.

Given Apple wants to increase the number of people who enter in stores in London every day,

let X be Apple’s target amount of people,

380 is double the difference between, the target amount of people which apple wants to visit the store every day and 100

difference between the target amount of people and 100 is

X - 100

double the equation = 2(X - 100)

the equation is equal to 380

2(X - 100) = 380

divide both sides by 2

X - 100 = 380/2

X - 100 = 190

X = 190 + 100

A standard normal random variable has a 0.3814 percent chance of falling between 0.3 and 3.2, according to the z table.

The probability is calculated by dividing the total number of outcomes by the total number of events.

Odds and probability are two different concepts.

Divide the probability of an event occurring by the probability that it won't happen to calculate chances.

The four main types of probability that mathematicians study are axiomatic, classical, empirical, and subjective.

So, the probability that a standard normal random variable will occur with a probability ranging from 0.3 to 3.2 must therefore be calculated.

First, a mean and standard deviation are introduced for a standard normal random variable.

The probability that a standard normal random variable will fall between 0.3 and 3.2 needs to be calculated.

Therefore, it should be more likely that:

P(0.3<z<3.2)=P(z<3.2)−P(z<0.3)

Using the usual value of z:

P(0.3<z<3.2)=0.9993−0.6179

Justify by saying:

P(0.3<z<3.2)=0.3814

Therefore, a standard normal random variable has a 0.3814 percent chance of falling between 0.3 and 3.2, according to the z table.

So the probability of winning $300 is 1/1315 & the probability of winning $201 is 7/196.

The probability of winning $300:

There are a total of 5 $100 bills + 8 $20 bills + 18 $5 bills + 35 $1 bills = 66 bills in the bag.

The probability of winning $300 by drawing 3 bills is the number of ways to select 3 $100 bills divided by the total number of possible combinations of 3 bills, which is:

(5 choose 3) / (66 choose 3) = (5! / (3! * (5-3)!) ) / (66! / (3! * (66-3)!)) = 10 / 13,145 = 1/1315

So the probability of winning $300 is 1/1315.

The probability of winning $201:

We can win $201 by drawing a $100 bill, a $50 bill (which can be achieved by drawing two $20 bills and putting back one), and a $1 bill.

The probability of winning $201 is the number of ways to select 1 $100 bill, 2 $20 bills (which can be rearranged into 1 $50 bill), and 1 $1 bill divided by the total number of possible combinations of 3 bills, which is:

(5 choose 1) * (8 choose 2) * (35 choose 1) / (66 choose 3) = (5 * 28 * 35) / 13,145 = 4900 / 13,145 = 7/196

So the probability of winning $201 is 7/196.

Probability is a mathematical concept that measures the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating that an event is impossible and 1 indicating that an event is certain to occur. A probability of 0.5, for example, indicates that an event is equally likely to occur or not occur.

Probabilities can be calculated based on the number of favorable outcomes divided by the number of possible outcomes in a given scenario. For example, if you roll a die, the probability of rolling a 6 is 1/6 because there is only 1 favorable outcome (rolling a 6) out of 6 possible outcomes (rolling a 1, 2, 3, 4, 5, or 6).

Probability is a key concept in statistics and is used to make predictions and decisions in fields such as finance, insurance, engineering, and more.

The total number of proper subsets of a set consisting of n elements is 2^n - 1.

A proper subset of a set is a subset that contains fewer elements than the original set. The total number of proper subsets of a set consisting of n elements is given by 2^n - 1.

This is because each element in the set can either be included or excluded in a subset, leading to 2^n possible combinations. However, the empty set (i.e., the subset with no elements) is not considered a proper subset, hence the total number of proper subsets is 2^n - 1.

For example, if n = 3, then the set has 8 possible subsets: {}, {1}, {2}, {3}, {1, 2}, {1, 3}, {2, 3}, and {1, 2, 3}. Out of these, only 7 are proper subsets. Hence,

The maximum probability of victory in this scenario is 50%.

Each player has an equal chance of rolling any number from 1 to 6, so the probability of rolling a specific number is 1/6.

The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.

Since the players cannot see their own outcome but can see the outcome of the other player, they must guess their own roll based on the observed roll of the other player. If the two players roll different numbers, one of them will have the correct guess, and their probability of winning is 1/6.

If the two players roll the same number, then both players have the same information and the probability of either player winning is still 1/6.

The maximum probability of victory is (1/6) + (1/6) = 1/3 + 1/3 = 2/3 = 50%.

The measure of the angles of a quadrilateral in ratio 3:20 is 15 and 100 degrees.

A quadrilateral is a flat shape with four edges and four corners, also known as vertices. The quadrilateral has angles at each of its four vertices, or corners. The angles at the vertices of a quadrilateral ABCD are A, B, C, and D. A quadrilateral has the following sides: AB, BC, CD, and DA.

Given that the 2 angles are in the ratio 3 : 20, then the measure of the angle can be taken as 3x and 20x.

We know that the sum of the internal angles of a quadrilateral is 360 thus:

160 + 85 + 3x + 20x = 360

23x = 115

x = 5

The measure of the angles are:

3x = 3(5) = 15
