The normal approximation is used to estimate probabilities in a medication study for weight gain as a side effect, providing insights into specific outcomes.

To approximate the probabilities using the normal approximation to the binomial, we need to know the success probability (percent of patients gaining weight) and the number of patients involved in the study. Let's denote the success probability as p and the number of patients as n.

(a) To calculate the probability that exactly k patients will gain weight, we can use the formula for the binomial distribution:

P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)

However, since we are using the normal approximation, we can approximate it as:

P(X = k) ≈ P(k - 0.5 < X < k + 0.5)

(b) To calculate the probability that no more than k patients will gain weight, we can sum the probabilities from 0 to k:

P(X ≤ k) ≈ P(0.5 < X < k + 0.5)

(c) To calculate the probability that at least k patients will gain weight, we can subtract the probability of the complement event (less than k patients) from 1:

P(X ≥ k) ≈ 1 - P(X < k + 0.5)

These approximations rely on the assumption that n is sufficiently large and that p is not too close to 0 or 1. The result suggests that we can estimate the probabilities of specific outcomes in the medication study using the normal distribution, providing an approximate understanding of the likelihood of different scenarios.

Therefore, D. 8 (9 + 5) is the answer.

Answer: mean-16.75

population size- 4

Step-by-step explanation:

Critical values of the function f(θ) = 2cos(θ) +(sin(θ))² on the interval 0≤ θ < 2π is 0 and π.

Therefore, the answer is 0 and π.

f(θ) = 2cos(θ) +(sin(θ))²

f'(θ) = -2sin(θ) +2sin(θ)cos(θ)

Critical values of f are points at which f' is zero or not defined.

For all values of θ, we can find that f'(θ) is defined.

f'(θ) = 0

-2sin(θ) +2sin(θ)cos(θ) = 0

cos(θ) - 1 = 0 or sin(θ) = 0

cos(θ) = 1

θ = nπ, n = 0, 1, 2, ...

sin(θ) = 0

θ = nπ, n = 0, 1, 2, ...

Therefore in the interval 0 ≤ θ < 2π, critical values are 0 and π.

2π is not there as it is not included in the interval.

Answer:

$149,000

Step-by-step explanation:

Subtract acc depreciation for 2020 from acc deprecitation in 2021 and it gives you the depreciation expense solely for 2021.

The Equipment was purchased during 2021 at $1,402,000.

The total amount of depreciation applied to an asset up to a particular point is known as accumulated depreciation. The beginning cumulative depreciation balance is increased with each period's depreciation expense.

Given:

Equipment purchased during 2021

= Cost of equipment on 12/31/2021 - (Cost of equipment on 12/31/2020 - Cost of equipment sold)

=  $2211000 - ( $2062000 - $470000)

= $2211000 - 15,92,000

= $6,19,000

Hence, the Equipment purchased during 2021 at $1,402,000.

Answer:

Step-by-step explanation:

To find the volume, we can multiply the area of the base by the height. The base is a triangle so its area is (4 * 3) / 2 = 6 and the height is 8 so the volume is 6 * 8 = 48 in³.

Answer:

C.  Vol = 48 in³

Step-by-step explanation:

Vol = base area of a triangle x height.

Vol = ( 1/2 * 3 * 4 ) x 8

Vol = 48 in³

Let G be a group, and let X be a G-set.

Show that if the G-action is transitive (i.e., for any x, y € X, there is g € G such that gx = y), and if it is free (i.e., gx = × for some g E G, x E X implies g = e), then there is a (set-theoretic) bijection between G and X.What is the proof of the above statement?

Suppose we have G-action, the action is free, and transitive; thus, we can create a function that is bijective. We will show that there is a bijective function by first constructing the following: Define a function f: G -> X that maps an element g € G to the element x € X with the property that gx = y for any y € X for the group.

That is, f(g) = x if gx = y for all y € X. Since the action is free, this function is one-to-one.Suppose x is any element of X. Since the action is transitive, there exists a g € G such that gx = x. Therefore, f(g) = x, which implies that f is onto. Therefore, f is a bijection, and G and X have the same cardinality.

Thus, distribution is a function that shows the possible values for a variable and how often they occur and categorical values are summarized by counts and/or percents

In statistics, the distribution is a function that shows the possible values for a variable and how often they occur.

The distribution of a data set is the shape of the graph when all possible values are plotted on a frequency graph. Usually, we are not able to collect all the data for our variable of interest. Therefore we take a sample. This sample is used to make conclusions about the whole data set.

The categorical variable is a data in which individuals are placed into groups or categories.

One way to summarize categorical data is to simply count (frequency), or tally up, the number of individuals that fall into each category. Another way is to show the percentage of individuals who fall into each category, thereby creating a relative frequency.

The sum of the diagonals of a rectangle = 223.6 cm if the area of the rectangle is 5000 cm².

Area can be defined as the quantum of material of a given consistence needed to make a model of the shape, or the quantum of makeup needed to cover the face with a single fleece. It's the two- dimensional fellow of the length of a wind or the volume of a solid.

Given,

Area of a cube = 5000 square cm

Also given that length is two times of the range also,

l = 2w

Area = l × w

5000 = 2w × w

2w ² = 5000

w ² = 2500

w = 50

also, l = 100

thus, l = 100 cm, w = 50 cm

Sum of the inclinations of a cube = √ l ² w ²

= √ 100 ² 50 ²

√ 10000 2500
