No, the probability be found by using the binomial probability formula with x counting the number who are left-handed. The correct option is (c) No, because the 100 adults were selected without replacement, the selections are dependent.

The binomial distribution assumes that the trials are independent, meaning that the outcome of one trial does not affect the outcome of any other trial. However, in this case, the 100 adults were selected without replacement, which means that the outcome of one selection affects the probability of the next selection. Therefore, the trials are dependent, and the binomial probability formula cannot be used.

Instead, we can use the hypergeometric distribution to calculate the probability of at least 30 left-handed adults in a sample of 100 adults selected without replacement from the U.S. population. The hypergeometric distribution takes into account the fact that the selections are dependent and is appropriate for this type of problem.

Therefore, the correct option is (c) No, because the 100 adults were selected without replacement, the selections are dependent.

The  1 c sugar is 200 grams.

Gram (originally grams; [1] SI unit symbol g) is a mass unit in the International System of Units (SI), equal to one thousandth of a kilogram.

Originally defined from 1795 as "the absolute mass of a volume of pure water equal to one hundredth of a cubic meter [1 cm3] and at the melting point of ice", [2] the defining temperature (~ 0 °C) ) was later changed to

°C, which is the maximum density of water to temperature.

At the end of the 19th century, however, an attempt was made to make the basic unit the kilogram and a unit derived from the gram. In 1960, the new International System of Units defined the gram as one thousandth of a kilogram (ie, a gram is 1 × 10–3 kg). As of 2019, the International Bureau of Weights and Measures defines the kilogram as a fixed numerical value of Planck's constant (h) of 6.62607015×10−3

52 °C is equal to 125.6  °F.

The Celsius( symbol °C) is an SI( International System of Units) deduced unit of temperature.

The Fahrenheit( symbol °F) is a unit of temperature that was extensively used previous to metrication.

How to Convert Celsius to Fahrenheit

F = [tex]\frac{9}{5}[/tex]C + 32

C = [tex]\frac{5}{9}[/tex](F - 32)

To convert 52 degrees Celsius to Fahrenheit,

We can use the following formula:

°F = (°C x 1.8) + 32

where °F is the temperature in Fahrenheit,

°C is the temperature in Celsius.

Substituting 52 for °C, we get:

°F = (52 x 1.8) + 32

Simplifying the expression:

°F = 93.6 + 32

°F = 125.6

Therefore, 52 degrees Celsius is equal to 125.6 degrees Fahrenheit.

The Bell Curve is a symmetrical curve that represents the probability distribution of a random variable.

The Bell Curve, also known as the normal distribution or Gaussian distribution, is a statistical concept used to describe the distribution of a set of data. The Bell Curve is a symmetrical curve that represents the probability distribution of a random variable.

The Bell Curve is often used to describe the distribution of scores on a test or exam. In this context, the Bell Curve is used to represent the distribution of scores across a population. The mean score (average score) is represented by the highest point on the curve, and the standard deviation is represented by the width of the curve.

In terms of percentages, the Bell Curve can be divided into different standard deviations, with each standard deviation representing a certain percentage of the population. The percentages of the population within each standard deviation are as follows:

68.27% of the population falls within one standard deviation of the mean.

95.45% of the population falls within two standard deviations of the mean.

99.73% of the population falls within three standard deviations of the mean.

These percentages are useful for understanding how scores or data are distributed across a population and can be used to set cutoff scores or define performance categories.

Step-by-step explanation:

Set the equations. Let the variable x denote the amount of months that are needed.

Silver Gym:

In Silver Gym, the membership is a flat fee (constant) of $45, and training sessions are $25 for each session (25x, x denoting the amount of sessions).

Therefore, total cost is:

Total Cost (c) = Training session x Training cost per session + Flat Fee

or

c = 25x + 45

Fit Factor:

In Fit Factor, the membership is a flat fee (constant) of $75, and training sessions are $15 for each session (15x, x denoting the amount of sessions).

Therefore, the total cost is:

Total Cost (c) = Training session x Training cost per session + Flat Fee

or

c = 15x + 75

~

You are trying to solve for the amount of training sessions that have to be bought in which both prices will be the same. Note that both equations are equal to c. Based on the transitive property of equality, if a = b and b = c, then a = c. Therefore:

c = 25x + 45

c = 15x + 75

15x + 75 = c = 25x + 45

15x + 75 = 25x + 45

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 25x and 75 from both sides of the equation:

15x (-25x) + 75 (-75) = 25x (-25x) + 45 (-75)

15x - 25x = 45 - 75

-10x = -30

Next, divide -10 from both sides of the equation:

(-10x)/-10 = (-30)/-10

x = -30/-10 = 3

If you are trying to find the missing measures of a rectangle, you should know that all rectangles have four sides, and each side has a length.

In other words, if you have a rectangle, two of the angles must be 90 degrees, and the other two angles must also be 90 degrees. To find the missing measures of a rectangle, you need to use the properties of rectangles.

First, find the length of each side. The length of all sides of a rectangle should be the same. Then, calculate the area of the rectangle. You can do this by multiplying the length of one side with the length of the other side.

Finally, you can use the Pythagorean Theorem to find the missing measures.

The Pythagorean Theorem states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

Using this theorem, you can find the length of the hypotenuse of the rectangle.

The hypotenuse side of a right-angled triangle's square is equal to the sum of the squares of the other two sides, according to Pythagoras' Theorem. The Perpendicular, Base, and Hypotenuse of this triangle are its three sides. Because to its position opposite the 90° angle, the hypotenuse in this case is the longest side. A right triangle's positive integer sides (let's say sides a, b, and c) are squared to obtain a Pythagorean triple equation.

An isometry is a transformation that retains congruence. In other words, a transformation in which the side lengths and angle measurements of the Image and Pre-Image are the same. Isometries include translations, reflections, and rotations. A translation is a "direct isometry" since it not only maintains congruence but also, unlike reflections and rotations, maintains orientation.

A dilation, on the other hand, is not an isometry since its Image is not consistent with its Pre-Image.

W=W [Width] (2)

P=2L+2W [perimeter] (3)

A=L*W = 198[area](4)

Subing (1) and (2) into (3) and (4)

A=W(4+2W)

Simplify

P=8+4W+2W=8+6W

A=4W+2W^2=198

A=2W^2+4W-198

Set equal to 0 and solve for W

W=(-b+√(b^2-4ac))/2a

W=(-b-√(b^2-4ac))/2a

W=(-4+√(4^2-4(2)(-198)))/(2(2)) = 9

W=(-4-√(4^2-4(2)(-198)))/(2(2)) =-11

Disregard W =-11 since distance can’t be negative and keep W=9. Plug W=9 into Length equation (1)
