Answer:

  (c)  15 units

Step-by-step explanation:

Given a right triangle with hypotenuse 17 and one leg 8, you want the measure of the other leg.

The Pythagorean theorem tells you the relationship between the sides of a right triangle:

  a² +b² = c² . . . . . . where c is the hypotenuse

  a² +8² = 17² . . . . . . using given values of b, c

  a² = 289 -64 = 225 . . . . subtract 8²

  a = √225 = 15

The length of segment BC is 15 units.

Additional comment

These side lengths {8, 15, 17} can be considered to be a "Pythagorean triple." It is one of a few that often appear in algebra and geometry problems. Others include {3, 4, 5}, {5, 12, 13}, {7, 24, 25}. Multiples of these are also commonly seen, such as 2×{3, 4, 5} = {6, 8, 10}.

There are 9 or 10 distinct ways to arrange 6 beads of distinct colors in a 2x3 grid if reflections and rotations are considered the same. We can solve this problem using Burnside's Lemma.

Burnside's Lemma states that for a group action on a set, the number of fixed points is given by the average over the group of the number of fixed points under a particular group element, where the average is taken over all group elements.

In this case, the group action is the action of rotating and reflecting the grid, and the set is the set of all possible bead arrangements in the grid. To use Burnside's Lemma, we need to find the number of fixed points (i.e., bead arrangements that are unchanged) under each group element, and then take the average over all group elements.

There are a total of $4$ rotations and $2$ reflections possible for a 2x3 grid.

The identity transformation keeps the grid in its original position, and thus there are

6!/(2!3!) = 60

The $90 rotation keeps $3 beads in the same place and switches the other $3, and similarly $180 and $270 rotation also keeps $3 beads in the same place and switches the other $3$, thus there are

3! = 6

The reflection on the horizontal axis keeps $3 beads in the same place and switches the other $3, and similarly the reflection on the vertical axis also keeps $3 beads in the same place and switches the other $3, thus there are

3! = 6

So the average number of fixed points is $(6+6+6+60)/8 = [tex]\frac{78}{8}[/tex] = 9.75$

So, there are 9 or 10 distinct ways to arrange 6 beads of distinct colors in a 2x3 grid if reflections and rotations are considered the same.

Solving the provided question, we can say that area of parallelograms = 1/2[( a +b)/ 2 ] = 1/2[( AB+EF)/ 2 ]

A parallelogram is a straightforward quadrilateral in Euclidean geometry that has two sets of parallel sides. In a particular kind of quadrilateral known as a parallelogram, both sets of opposite sides are parallel and equal. There are four different kinds of parallelograms, including three unique kinds. Parallelograms, squares, rectangles, and rhombuses are the four different shapes. Having two sets of parallel sides makes a quadrilateral a parallelogram. In a parallelogram, the opposing sides and angles are both the same length. On the same side of the horizontal line, the interior angles are additional angles as well. 360 degrees is the total number of interior angles.

If the first two selections were boys, the way that it affects the probability of the third candidate being a girl is; It increases the probability of a girl being the third candidate.

Conditional probability in mathematics is defined as the type of probability that depends on the occurrence or outcome of another event.

Now, we are told that in the school;

Number of Girls = 7

Number of boys = 3

Since the staff is choosing the candidates at random, then it means everyone has an equal chance to be picked.

Now, since we are told that 2 boys are selected first, it means that there would be only 1 boy left and as such the probability of selecting a girl will increase because there would now be seven girls out of 8 people.

a) The probability that a person has the virus given that they have tested positive is 0.5.

b) The probability that a person does not have the virus given that they test negative is 0.9.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.

Virus infects one in every 400 people.

Let A = be the event of being infected.

Let A' = be the event of not being infected.

Let B = be the event of being tested positive.

Let B' = be the event of being tested negative.

Let the population = 1,00,000

So, now the number of infected people are -

Infected people = (1/400) 100000

Infected people = 250

The number of non-infected people are -

Non-Infected people (T') = 100000 - 250

Non-Infected people (T') = 99750

The test is 80% positive when the person has the virus -

N(A|B) = 0.80 × 250

N(A|B) = 200

So, the probability value for N(A|B) -

P(A|B) = 200/400 = 0.5

The test is 10% positive when the person does not have the virus -

N(A'|B) = 0.10 × 99750

N(A'|B) = 9975

Number of people who test negative when they don't have the virus -

N(A'|B') = (T') - N(A'|B)

N(A'|B') = 99750 - 9975

N(A'|B') = 89775

So, the probability value for N(A'|B') -

P(A'|B') = 89775/99750 = 0.9

Therefore, the probabilities are 0.5 and 0.9.

The required required value of G is 1) 2.11 × 10^7 2) 2.06 × 10^7.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

We have,

1) m = 6. 1 x 10^-5, t = 1. 7 x 10^-6

G = m/t^2

G =6. 1 x 10^-5/(1. 7 x 10^-6)^2

G = 2.11 × 10^7

2)m is increased by 8%

New m = 6.59 x 10^-5,

t is increased by 5%

New t = 1.79  x 10^-6

So

G = m/t^2

G = 6.59 x 10^-5/(1.79  x 10^-6)^2

In a month with 30 days, the family would use

If each shower head delivers 5 gallons/minute, then the family would use 1200 minutes * 5 gallons/minute = 6000 gallons of water per month on showering.

The amount of water used by this family just on showering is more than half of the total amount of water used by the average family in a month.

Additionally, using standard flow shower heads can help to reduce water usage.
