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.

Answer:

Step-by-step explanation:

Take 3.14 and multiply it by 2.5

Step-by-step explanation:

To find the vector parametric equation for the parabola from the origin to a point P, we need to express the position vector of P as a function of a parameter. Let's assume the coordinates of P are (x, y).

(a) Vector Parametric Equation for the Parabola: We can represent the position vector of P as a linear combination of two vectors. The first vector will point from the origin to P, and the second vector will be perpendicular to it.

Let's consider the vector from the origin to P as OP. Since P lies on the parabola, the magnitude of OP is given by the equation y = x^2. Therefore, the magnitude of OP is √(x^2 + (x^2)^2) = √(x^2 + x^4).

The unit vector in the direction of OP can be found by dividing OP by its magnitude: u = OP / √(x^2 + x^4).

To find a perpendicular vector, we can take the cross product of u with the vector (0, 0, 1) (which is perpendicular to the xy-plane). This will give us a vector perpendicular to the plane containing the parabola.

Let's call the perpendicular vector v. The cross product of u and (0, 0, 1) is given by: v = u × (0, 0, 1).

Finally, the vector parametric equation for the parabola from the origin to P is given by: r(t) = tu + tv, where t is the parameter ranging from 0 to 1.

(b) Line Integral along the Parabola: To find the line integral of a vector field F along the parabola from the origin to P, we need to evaluate the line integral: ∫(F · dr) from 0 to 1, where F is the vector field, dr is the differential vector along the parabola, and the integral is taken with respect to t.

The line integral can be calculated as follows: ∫(F · dr) = ∫(F · (du/dt) dt), where du/dt is the derivative of the unit vector u with respect to t.

Substituting r(t) = tu + tv into the above expression, we can find the line integral.

Please provide the vector field F so that I can assist you further in evaluating the line integral.

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

The equation will be 5d + 1 = 16 and the distance from Pablo's house to school will be d = 3 miles.

It is given that distance from Pablo's house to mall is 1 more than 5 times the distance from his house to his school.  Also ,  the distance from Pablo's house to the mall is 16 miles.

We have to find out an equation and distance d from Pablo's house to his school.

What will be the expression for 2 times of a number x added with 2 ?

The expression will be 2x+2.

Let's assume the distance from Pablo's house to his school is d miles.

The distance from Pablo's house to the mall will be ;

= 5d + 1

This distance will be equal to 16 miles as given in the question.

∴ The equation will be ;

    5d + 1 = 16

Now to find the distance from Pablo's house to his school, we have to solve this equation. The distance will be

   5 × d = 15

    or

   d = 3 miles

Thus, the equation will be 5d + 1 =16 and the distance from Pablo's house to school will be d = 3 miles.

a) Time cannot be negative, we discard the negative value and conclude that it will take approximately 14.09 hours for the truck to reach its destination.

b) The car should travel at a constant speed of approximately 31.06 miles per hour to reach the destination at the same time as the truck.

a. To find the number of hours it will take the truck to reach its destination, we need to set up the equation d = 437.75 and solve for t.

The equation representing the truck's distance from the warehouse is given as d = t^2 + 70t. By substituting 437.75 for d, we have:

437.75 = t^2 + 70t

To solve this equation, we can rearrange it into a quadratic equation:

t^2 + 70t - 437.75 = 0

Using a graphing calculator or factoring, we find that the equation can be factored as (t + 35)(t + 35) - 437.75 = 0. Simplifying this equation gives us:

(t + 35)^2 - 437.75 = 0

Next, we can solve for t by taking the square root of both sides of the equation:

t + 35 = ±√437.75

t + 35 = ±20.91

Solving for t gives us two possible solutions:

t = -35 + 20.91 = -14.09
t = -35 - 20.91 = -55.91

Since time cannot be negative, we discard the negative value and conclude that it will take approximately 14.09 hours for the truck to reach its destination.

b. To find the constant speed at which the car should travel to reach the destination at the same time as the truck, we need to determine the time it takes for the truck to reach the destination and the distance between the warehouse and the destination.

We already know that it takes approximately 14.09 hours for the truck to reach the destination. The distance between the warehouse and the destination is given as 437.75 miles.

Using the formula speed = distance / time, we can calculate the constant speed the car should travel:

speed = 437.75 miles / 14.09 hours

Calculating this gives us:

speed ≈ 31.06 miles per hour

Therefore, the car should travel at a constant speed of approximately 31.06 miles per hour to reach the destination at the same time as the truck.

The B-coordinate vector of x is then: [x]_B = [\begin{array}{c} c1 \\ c2 \end{array}\right]

To find the B-coordinate vector of x, we need to express x as a linear combination of the basis vectors b1 and b2. Since x is in the subspace H with a basis B = {b1, b2}, we know that any vector in H can be expressed as a linear combination of b1 and b2. So we have:

x = c1*b1 + c2*b2

where c1 and c2 are scalars. To find the B-coordinate vector of x, we need to solve for c1 and c2. We can do this by setting up a system of equations:

1*c1 - 3*c2 = x1
4*c1 - 11*c2 = x2
-3*c1 + 8*c2 = x3

where x1, x2, and x3 are the components of x. This system can be written in matrix form as:

[\begin{array}{cc} 1 & -3 \\ 4 & -11 \\ -3 & 8 \end{array}\right] [\begin{array}{c} c1 \\ c2 \end{array}\right] = [\begin{array}{c} x1 \\ x2 \\ x3 \end{array}\right]

We can solve for c1 and c2 using row reduction or matrix inversion. The B-coordinate vector of x is then:

[x]_B = [\begin{array}{c} c1 \\ c2 \end{array}\right]

Note that we only need two basis vectors to find the B-coordinate vector of x, since H is a two-dimensional subspace. The third basis vector b3 is not needed.

Answer:

Step-by-step explanation:

c.  y = (x^2 + 3)(x + 4)

y = x^3 + 4x^2 + 3x + 12

d. y = (x^2 + x) / √x

y =   (x^2 + x) /  x^1/2

y = x^2/ x^1/2  +  x / x^1/2

y = x^(2 - 1/2) + x(1 - 1/2)

y = x^3/2 + x^1/2

Answer: Option C, the median is 5.

Step-by-step explanation:

The median is the value that is just in the middle of our data set (the possible values in the histogram)

the set is S = {2, 3, 4, 5, 6, 7, 8, 9}

And if we take in account the number of times that each value is repeated, we get:

S = {2, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 6, 6, 7, 7, 8, 9}

So we have 17 values, and the one exactly in the middle will be the median.

To find the point in the middle, we can use that we have 17 values, because 17 is odd, we can do

17 - 1 = 16

16/2 = 8.

17 - 8 = 9.

Then the 9nth point is our median:

the 9th point is a 5.

Then the correct option is C

B) Yes they care because we reject the null hypothesis.

The marketing analyst performed a chi-square test in order to determine if there were differences in the preferences of car colors by women. The null hypothesis states that there is no difference in the proportions of car color preferences among women. By running the chi-square test with the given data, the analyst received a p-value of 0.000, which is less than 0.05, the significant level set at 5%.

This indicates that the differences in proportions of car color preference among women are statistically significant. Therefore, the null hypothesis is rejected and the conclusion is that women do care about the color of their cars.

The two cases weigh 102,100 decigrams together.

First, we need to convert dekagrams to decigrams, since the question asks for the weight in decigrams.

1 dekagram = 10 grams

1 gram = 10 decigrams

Therefore, 1 dekagram = 100 decigrams

Now, let's calculate the weight of the two cases in decigrams:

Weight of tomato cans case = 563 dekagrams x 100 decigrams/dekagram = 56,300 decigrams

Weight of soup cans case = 458 dekagrams x 100 decigrams/dekagram = 45,800 decigrams

The weight of the two cases together is the sum of the two weights:

Total weight = 56,300 decigrams + 45,800 decigrams = 102,100 decigrams

Therefore, the two cases together weigh 102,100 decigrams.

To solve this problem, we need to first convert the weight of the two cases from dekagrams to decigrams so we can add them together.

1 dekagram = 10 grams

1 gram = 10 decigrams

So,

563 dekagrams = 5630 grams

5630 grams = 56300 decigrams

and

458 dekagrams = 4580 grams

4580 grams = 45800 decigrams

Now we can add the weights of the two cases in decigrams:

56300 decigrams + 45800 decigrams = 102,100 decigrams

Therefore, the two cases weigh 102,100 decigrams together.
