The number of combinations of 6 boys and 20 girls that can exist among 26 children born in a hospital on a given day is 230,230.

]To calculate the number of combinations, we can use the concept of binomial coefficients. The formula for calculating the number of combinations is C(n, k) = n! / (k!(n-k)!), where n is the total number of objects and k is the number of objects we want to select.

In this case, we have 26 children in total, and we want to select 6 boys and 20 girls. Plugging these values into the formula, we get C(26, 6) = 26! / (6!(26-6)!) = 230,230. Therefore, there are 230,230 different combinations of 6 boys and 20 girls that can exist among the 26 children born in the hospital on that given day.

1) The amplitude c+ is c+l

2) The expectation value is 0

3) The uncertainty ΔSX is √(3/7) c+.

Now, we know that any wave function can be written as a linear combination of two spin states (up and down), which can be written as:

Ψ = c+ |+> + c- |->

where c+ and c- are complex constants, and |+> and |-> are the two orthogonal spin states such that Sx|+> = +1/2|+> and Sx|-> = -1/2|->.

Hence, we can write the given wave function as:Ψ = c+|+> + i/√7|->

Now, we know that the given wave function has been defined in Sx basis, and not in the basis of |+> and |->.

Therefore, we need to write |+> and |-> in terms of |l> and |r> (where |l> and |r> are two orthogonal spin states such that Sy|l> = i/2|l> and Sy|r> = -i/2|r>).

Now, |+> can be written as:|+> = 1/√2(|l> + |r>)

Similarly, |-> can be written as:|-> = 1/√2(|l> - |r>)

Therefore, the given wave function can be written as:Ψ = (c+/√2)(|l> + |r>) + i/(√7√2)(|l> - |r>)

Therefore, we can write:c+|l> + i/(√7)|r> = (c+/√2)|+> + i/(√7√2)|->

Comparing the coefficients of |+> and |-> on both sides of the above equation, we get:

c+/√2 = c+l/√2 + i/(√7√2)

Therefore, c+ = c+l

The amplitude c+ is a real number and is equal to c+l

The expectation value of the operator Sx is given by: = <Ψ|Sx|Ψ>

Now, Sx|l> = 1/2|r> and Sx|r> = -1/2|l>

Hence, = (c+l*) + (c+l) + (i/√7) - (i/√7)(c+l*)= -i/√7(c+l*) + i/√7(c+l)= 2i/√7 Im(c+)

As c+ is a real number, Im(c+) = 0

Therefore, = 0

The uncertainty ΔSX in the state |Ψ> is given by:

ΔSX = √( - 2)

where = <Ψ|Sx2|Ψ>and2 = (<Ψ|Sx|Ψ>)2

Now, Sx2|l> = 1/4|l> and Sx2|r> = 1/4|r>

Hence, = (c+l*) + (c+l) + (i/√7) - (i/√7)(c+l*)= 1/4(c+l* + c+l) + 1/4(c+l + c+l*) + i/(2√7)(c+l* - c+l) - i/(2√7)(c+l - c+l*)= = 1/4(c+l + c+l*)

Now,2 = (2i/√7)2= 4/7ΔSX = √( - 2)= √(1/4(c+l + c+l*) - 4/7)= √(3/14(c+l + c+l*))= √(3/14 * 2c+)= √(3/7) c+

Answer:

To calculate George's new weekly pay rate after a 20% raise, we can use the following formula:

New weekly pay rate = Old weekly pay rate + (Old weekly pay rate x Percent raise)

Or, mathematically:

New weekly pay rate = 455 + (455 x 0.20)

Simplifying the calculation:

New weekly pay rate = 455 + 91

New weekly pay rate = 546

Therefore, George's new weekly pay rate is $546.

Out of the given options, the calculations that will result in George's new weekly pay rate are:

multiply $455 by 1.20

solve for x: x/455 = 120/100 (this is equivalent to multiplying $455 by 1.20)

Answer:

Step-by-step explanation:

given the roots of a polynomial x = a, x = b , x = c

then the factors are (x - a) , (x - b) , (x - c)

the polynomial is then the product of the factors

y = (x - a)(x - b)(x - c)

here the roots , where the graph crosses the x- axis, are

x = - 4 , x = - 2 , x = 1

then the factors are

(x - (- 4) ) , (x - (- 2) ) , (x - 1) , that is

(x + 4) , (x + 2) , (x - 1)

Then

y = (x + 4)(x + 2)(x - 1)

Since there are complementary angles, the value of angle B is 39°.

Angle A = 7x + 23°

Angle B = 5x + 19°

It should be noted that the total angles in a complementary angle are equal to 90°.

Therefore, we need to add angle A and B together and then equate them to 90°. This will be:

7x + 23° + 5x + 19° = 90°

Collect like terms

12x + 42° = 90°

12x = 90° - 42°

12x = 48°

x = 48°/12

x = 4°

Angle A = 7x + 23° = 7(4) + 23° = 28° + 23° = 51°

Angle B = 5x + 19° = 5(4) + 19° = 20° + 19° = 39°

The value of angle B is 39°.

Answer:

50 inches

Step-by-step explanation:

Given that

5 equal sized square shelves arranged in a column.

Total area of five shelves = 500 sq inches

To find:

Length of shelving unit = ?

Solution:

First of all, let us find the area of each shelving unit.

Area of each shelving unit = Total area of five shelved divided by 5

Area of each shelving unit = 500 \(\div\) 5 = 100 sq units.

Each shelving unit is of square shape and area of a square is given as:

Area = \(Side^2\)

100 = \(Side^2\)

So, side of shelve = 10 inches

Now, there are 5 squares in the shelving unit.

So, length of shelving unit = \(10 \times 5 = \bold{50 \ inches}\)

The total number of tasks Terrence completed. By substituting the value of 'x' with the number of tasks Terrence completed

The factor 'x' in the expression '90x - 20' represents the total number of tasks that Terrence completed in the game.

To understand why, let's break down the given information. It states that Shelly and Terrence completed a different number of tasks. Shelly earned 90 points on each task, so the total number of tasks she completed is not represented by 'x'.

On the other hand, Terrence's total points were 20 less than Shelly's total. This means that Terrence's total points can be calculated by subtracting 20 from Shelly's total points. Since Shelly earned 90 points on each task, her total points would be 90 multiplied by the number of tasks she completed.

So, the expression '90x - 20' represents Terrence's total points in the game, where 'x' represents the total number of tasks that Terrence completed. By substituting the value of 'x' with the number of tasks Terrence completed, we can calculate his total points.

Therefore, the correct answer is: The total number of tasks Terrence completed.

Probability is a measure of how likely an event is to occur. It is a value between 0 and 1, with 0 indicating that an event is impossible and 1 indicating that an event is certain to occur.

In this case, we're looking at the probability of certain outcomes related to the written driving test in Florida. The failure rate for this test is 60 percent, which means that the probability of failing the test is 0.6 and the probability of passing the test is 0.4.

a. To find the probability of all three test-takers failing the test, we can use the formula for the probability of independent events:

P(A and B and C) = P(A) x P(B) x P(C)

Where P(A), P(B), P(C) are the probability of each test-taker failing the test.

So in this case:

P(all three fail the test) = 0.6 x 0.6 x 0.6 = 0.216

The probability of all three test-takers failing the test is 0.216 or 21.6%.

b. To find the probability of none of the test-takers failing the test, we can use the formula for the probability of independent events:

P(A and B and C) = P(A) x P(B) x P(C)

Where P(A), P(B), P(C) are the probability of each test-taker passing the test.

So in this case:

P(none fail the test) = 0.4 x 0.4 x 0.4 = 0.064

The probability of none of the test-takers failing the test is 0.064 or 6.4%.

c. To find the probability of only one of the test-takers failing the test and two passing, we can use the combination formula:

(3 choose 1) x P(fail) x P(pass)^2 = 3 x (0.6 x 0.4^2) = 0.288

The probability of only one test-taker failing the test is 0.288 or 28.8%.

In summary, Probability is a measure of how likely an event is to occur, in this case we're looking at the probability of certain outcomes related to the written driving test in Florida, the failure rate for this test is 60 percent, which means that the probability of failing the test is 0.6.

To find the probability of all three test-takers failing the test we can use the formula P(A and B and C) = P(A) x P(B) x P(C) where P(A), P(B), P(C) are the probability of each test-taker failing the test.

To find the probability of none of the test-takers failing the test we can use the formula P(A and B and C) = P(A) x P(B) x P(C) where P(A), P(B), P(C) are the probability of each test-taker passing the test, and to find the probability of only one of the test-takers failing the test and two passing,

Two similar figures have a ratio of areas 72:32. The ratio of similarity between the two figures is 3:2.

The ratio of areas of two similar figures is equal to the square of the ratio of their corresponding side lengths. Let's assume the ratio of side lengths is a:b.

Given: Ratio of areas = 72:32

The ratio of areas is the square of the ratio of side lengths. So, we have:

(a/b)^2 = 72/32

Simplifying the equation:

(a/b)^2 = 9/4

Taking the square root of both sides:

a/b = √(9/4)

a/b = 3/2

Hence, the ratio of side lengths of the two similar figures is 3:2.

Since similarity is based on corresponding side lengths, the ratio of similarity is the same as the ratio of side lengths. Therefore, the ratio of similarity between the two figures is 3:2.

This means that for every unit increase in the length of the corresponding side in the smaller figure, the corresponding side in the larger figure increases by 1.5 units.

In summary, the ratio of similarity between the two figures is 3:2, indicating that they are scaled versions of each other with the smaller figure being 3/2 times smaller in each dimension compared to the larger figure.

Hence, the ratio of similarity is 3:2.
