In the country of United States of Heightlandia, the height measurements of ten-year-old children are approximately normally distributed with a mean of 53.6 inches, and standard deviation of 2.8 inches.
A) What is the probability that a randomly chosen child has a height of less than 49 inches? (Round to 3 decimal places.)
B) What is the probability that a randomly chosen child has a height of more than 48.8 inches? (Round to 3 decimal places.)

Answers

The likelihood that a randomly selected youngster is under 49 inches tall is 0.989

The likelihood that a randomly selected child would be taller than 48.8 inches is 0.875.

Let the X represent a ten-year-old child's height measurements.

As a result, with a mean of 56.2 inches and a standard deviation of 3.3 inches, X follows the normal distribution.

A) We need to calculate the likelihood that a youngster selected at random is under 63.75 inches tall.

Specifically,

P(X < 63.75)

The Z score calculation gives us

Z = (X - μ)/σ

where mean is and standard deviation is.

Z = (63.75 - 56.2)/3.3

Z = 2.288 as a result.

According to the z distribution table, the value is around 0.989

B) Similar to this, the Z score formula gives us

Z = (X - μ)/σ

where μ mean is and σ standard deviation is.

Therefore, we must determine the likelihood that a child picked at random will be taller than 60 inches.

Z = (60 - 56.2)/3.3

Z = 1.1515

The number is around 0.875 according to Z score.

Let S be a subset of R that is closed under multiplication (that is, if a and b are in S, then so is ab). Let Tand Ube disjoint subsets of S whose union is S .Given that the product of any three (not necessarily distinct) elements of T is in T and that the product of any three elements of U is in U, show that at least one of the two subsets T, U is closed under multiplication.

We start out with the assumption that neither T nor U is closed under multiplication and use proof by contradiction to prove that at least one of T or U must be closed under multiplication.

If t1, t2 ,t3 ∈T and u1 ,u2 , u3 ∈U, it is given by the problem that t1⋅t2⋅t3∈T

and u1⋅u2⋅u3∈U. Also, T and U are disjoint subsets of S and therefore, T∩U = ∅ Now let t3=u1⋅u2 and u3=t1⋅t2. These statements are valid because T and U are not closed under multiplication, so the product of u1⋅u2 must not be in the set U and the product of t1⋅t2 must not be in set T.

Then t1⋅t2⋅t3∈T is equivalent to t1⋅t2⋅u1⋅u2∈Tand u1⋅u2⋅u3∈U is equivalent to u1⋅u2⋅t1⋅t2∈U

However, this is a contradiction because these products both are the same —t1⋅t2⋅u1⋅u2— but T∩U= ∅ because Tand U are disjoint. Then the original assumption that "neither T nor U is closed under multiplication" must have been wrong, and at least one of T or U must be closed under multiplication.

Let L represent the number of workers hired by a firm, and let Q represent that firm's quantity of output.

Then the marginal product of the 13th worker isa.) 8 units of output.b.) 10 units of output.c.) 122 units of output.d.) 132 units of output.

Answers

The amount of marginal product of the 13th worker is 10 units of output, which is the difference between the quantity of output when L = 12 (122) and when L = 13 (132).

The marginal product of the 13th worker can be calculated as follows:

Marginal product = Quantity of output for L = 13 - Quantity of output for L = 12

Marginal product = 132 - 122

Marginal product = 10 units of output

The marginal product of the 13th worker is the additional output created by hiring one additional worker. This is calculated by taking the difference between the quantity of output when the number of workers is 12 and when it is 13. In this case, the quantity of output when L = 12 is 122, and when L = 13 it is 132, so the marginal product is 10 units of output. This calculation shows that the 13th worker is adding 10 units of output to the firm's total production. This is an important concept in production economics, as it helps firms determine the optimal number of workers to hire in order to maximize their output and profits.

Answers

A function with an infinite number of critical points can be expressed as a continuous function with a derivative that is equal to zero at every point in its domain.

For example, the function f(x) = 0 has an infinite number of critical points since its derivative f'(x) = 0 for every x in its domain. Alternatively, a function that has every point as a critical point can be expressed as a function with a derivative that is always equal to zero. For example, the constant function f(x) = c has a derivative f'(x) = 0 for every x in its domain, and thus every point in its domain is a critical point.

In addition, an example of a function with every point as a critical point is the constant function, f(x) = c, where c is a constant. The derivative of this function is f'(x) = 0, which means that the derivative is zero for all values of x. Therefore, every point of the constant function is a critical point.

1. 63g/7cm³ = 9 g/cm³

The density of a substance indicates how dense it is in a given area. Mass per unit volume is the definition of a material's density. In essence, density is a measurement of how closely stuff is packed. It is a particular physical characteristic of a specific thing.

The unit g/cm³ is a unit for measuring density.

Therefore, the division of measurements is possible.

2. The m or mm must be converted so that the units are the same.

1 m = 1000 mm.

Convert the meters to mm:

0.080 m = 80 mm.

Let x represent the number of hours that Fin volunteers. Which is the equation that would answer this question?
x+ 2x +1.5 = 12
x+x+x+1.5 = 12
x+ 2(x+1.5) = 12
x+ (2x +1.5) = 12

Answers

The equation that would answer this question is x + (2x + 1.5) = 12. where x is the number of hours that Fin volunteers, and 2x + 1.5 represents the number of hours that each of his friends volunteers.

How to find the equation?

In this scenario, you can set up an equation that represents the total amount of time Fin and his friends volunteer. Let 'x' be the number of Finn's volunteer hours. His friends volunteer 1.5 hours more than Finn, so the number of hours each friend volunteers can be represented by x + 1.5. The total number of hours that all three friends volunteered can be expressed as:

x + (x + 1.5) + (x + 1.5) = 12

Expansion of the 2nd and 3rd terms:

x + x + 1.5 + x + 1.5 = 12

Combining the same terms:

3x + 4.5 = 12

Subtract 4.5 from both sides:

3x = 7.5

Divide both sides by 3:

x = 2.5

So Fin volunteers his 2.5 hours.

Let a represent the top speed of bird A and b represent the top speed of bird B.

A bird of species A, when diving, can travel 5 times as fast as a bird of species B top speed, hence:

a = 5b

a - 5b = 0 (1)

If the total speeds for these two birds is 222 miles per hour, hence:

a + b = 222 (2)

To solve by elimination method, subtract equation 2 from 1, hence:

-6b = -222

Dividing by -6:

b = 37

Put b = 37 in equation 2:

a + 37 = 222

a = 185

The speed of the bird are 185 miles per hour and 37 miles per hour
