in option A and B a right triangle is formed when three squares are joined at their vertices, the area of the largest square is the same as the combined area of the two smaller squares.

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

A) From the given figure, side of a largest square is 17 inches, side of a larger square is 15 inches and the area of a smaller square is 64 square inches.

We know that, the area of a square is side².

The side(c) of a smaller square is side²=64

Then, c=8 units

By using Pythagoras theorem, we get

17²=15²+c²

289=225+8²

289=289

B) From the given figure, area of a largest square is 169 square inches, area of a larger square is 144 square inches and the side of a smaller square is 5 inches.

We know that, the area of a square is side².

The side(a) of a largest square is side²=169

Then, a=13 inches

The side(b) of a larger square is side²=144

Then, b=12 inches

By using Pythagoras theorem, we get

13²=12²+5²

169=144+25

169=169

Therefore, in option A and B a right triangle is formed when three squares are joined at their vertices, the area of the largest square is the same as the combined area of the two smaller squares.

Answer:The box plots for Theo’s math scores and language arts scores.

2 box plots. The number line goes from 50 to 100.

For math, the whiskers range from 55 to 90, and the box ranges from 60 to 85. A line divides the box at 80.

For language arts, the whiskers range from 50 to 90, and the box ranges from 60 to 80. A line divides the box at 70.

About 50% of Theo’s scores are in which range for each subject?

60 to 85 for math; 60 to 80 for language arts

55 to 90 for math; 50 to 90 for language arts

55 to 60 for math; 50 to 60 for language arts

85 to 90 for math; 80 to 90 for language arts

Step-by-step explanation:

the whiskers range from 55 to 90 =>   ( min 55 , max 90  , range = 90-55 = 45)

the box ranges from 60 to 85.  =>  (Q₁ = 60 and Q₃ = 85)

A line divides the box at 80   => (Q₂ = Median = 80)

For language arts,

the whiskers range from 50 to 90 => ( min 50 , max 90  , range = 90-50 = 40)

the box ranges from 60 to 80.  =>  (Q₁ = 60 and Q₃ = 80)

A line divides the box at 70.  => (Q₂ = Median = 70)

50% of Theo’s scores lies between Q₁ and Q₃

It will take the lizard 19 days to reach the top of the well.

As per the data given,

We have,

The depth of the well = 19 feet

Let's call the number of days the lizard has been in the well as "d".

After "d" days, the lizard will have crawled up a total of 5d feet.

However, it will also have slipped back down 4d feet during the nights.

So, the net distance the lizard has traveled upward can be calculated as follows:

Net distance = 5d - 4d = d feet

To reach the top of the well (19 feet), the lizard must have traveled 19 feet upward, so we have:

Answer:

Step-by-step explanation:

The sum of two supplementary angles is 180

Let A be the larger angle and B be the smaller angle

A+B=180

Given A=5B-18

5B-18+B=180

6B=180+18=198

B=198/6=33

A=180-B=180-33=147

Hence A=147, B=33

The point on the curve with a slope of −93–√2 is (2, 0.43)

Given x(t) = 2 sin(8t) and y(t) = −9 cos(8t)

We are asked to determine the points on the curve with a slope of −93–√2.

Now, x/2 = sin(8t)   --(1)

       -y/9 = cos(8t)   --(2)

Squaring and adding equations (1) and (2)

               (x/2)² + (-y/9)² = sin²(8t) + cos²(8t)

                   x²/4 + y²/81 = 1

Differentiating both sides

                 x/2 + (2y/81) (dy/dx) = 0

Given slope = dy/dx = −93–√2

                 (2sin(8t))/2 + (2(−9 cos(8t))/81)(-93 - √2) = 0

                   sin(8t) + (2/9)cos(8t)(93 + √2) = 0

Solving for t and taking care of 0 ≤ t <π/8

                 we get t = 11.59°, 34.09°, 79.09°......

But only t within the given range is t = 11.59°.

Now, x = 2sin(8 x 11.59°) = 2

and y = -9 cos(8 x 11.59°) = 0.43

Hence, the point on the curve with a slope of −93–√2 is (2, 0.43)

The probability that a state is occupied by an electron at

i)1kt:0.5

ii) 3kt: 0.7

ii)5kt: 0.9

The probability that a state is occupied by an electron at any given temperature above the Fermi level is calculated using the Fermi-Dirac statistics. This equation states that the probability of a state being occupied is equal to 1/(1+exp(-(E-EF)/KT)), where E is the energy of the state, EF is the Fermi level energy, and KT is the product of Boltzmann's constant and the temperature in Kelvin.

Thus, for a temperature of 1kt above the Fermi level, KT = 1. By plugging these values into the equation, we can calculate that the probability of a state being occupied is 0.5. For a temperature of 3kt and 5kt above the Fermi level, KT = 3 and 5, respectively. Using these values, the probability of a state being occupied at 3kt and 5kt above the Fermi level is 0.7 and 0.9, respectively.

The probability of two or more events happening simultaneously is 0.36.

The probability of two or more events happening simultaneously depends on the number of events and the type of relationship between them. If the events are independent, meaning that the occurrence of one event does not affect the probability of the other event happening.

The probability of two or more events happening simultaneously can be calculated using the formula for the sum of probabilities:

P(A or B) = P(A) + P(B) - P(A and B)

Where A and B are two events. If we have n independent events with the same probability of 20%, the probability of two or more events happening simultaneously can be calculated as follows:

P = 1 - P(none of them happen) = 1 - (1 - 0.2)ⁿ

For n = 2, we have:

P = 1 - (1 - 0.2)² = 1 - 0.64 = 0.36

So, the chance that two events with a 20% probability will happen simultaneously is 36%. The chance for three or more events is even higher.

It's important to note that if the events are dependent, the calculation will be different. The relationship between the events can significantly impact the final probability.

The concept that will be used here is commision and percentage.

A. Therefore, a commission is often a percentage of a sale. Suppose, for illustration, that I own a cookie company. I take you on as a seller and inform you that you will receive a 10% commission for each box you sell. Given that the box of cookies costs $5.00,

you would get $5.00 * (.10), or $0.50, for each successful box you sell. Therefore, if you sell 200 boxes in a week and earn $0.50 per box, your total commission would be $0.50 * 200 = $100!

Thus, Tyler's brother sold shoes valued a total of $900. In the event that he earns a 2.5% commission, his reward will be [ $900 * (0.025) ]= $22.50 for his work.

By asking about their ability to stand, the nurse can determine if alternative methods of measurement need to be used, and can also identify any underlying health issues that need to be addressed

When a patient is admitted to a healthcare facility, one of the first things the healthcare provider does is gather information about the patient's physical characteristics. This includes measuring the patient's height and weight.

As part of the preparation process for measuring height and weight, the nurse may ask the patient about their ability to stand. There are several reasons why this is important.

First, the most accurate way to measure height is to have the patient stand upright, with their head facing forward and their feet together. If the patient is unable to stand, the nurse may have to use alternative methods to measure height, such as a measuring tape, which may not be as accurate.

Second, standing is also the most accurate way to measure weight. If the patient is unable to stand, the nurse may have to use a bed scale, which may not provide an accurate measurement of the patient's weight.

Finally, asking the patient about their ability to stand helps the nurse to determine if there are any underlying health issues that need to be addressed. For example, if the patient is unable to stand, it may indicate that they have a mobility issue that needs to be addressed.
