There will be 49 pink beads in Jada's storage container.

The weighted sum is applied to the expected value in parameter estimation. Informally, the expected value is the simple average of a large number of outcomes that were chosen at random and were calculated independently.

A bundle from Jada holds 175 hair beads. Without even glancing at the beads, she chooses one, notes the color, and puts it back in the box. She speaks more than once in the same way. The table below displays the results. Jada's cousin desires to have pink beads placed in her hair.

The expected value is given below.

E(x) = np

Where n is the number of samples and p is the probability.

The table is given below.

Color    Frequency

Pink               7

Green           8

Red              10

Total            25

The probability of getting pink will be given as,

p = 7/25

p = 0.28

Then the expected value of pink will be given as.

E(pink) = 175 x 0.28

E(pink) = 49

Thus, the number of pink beads in Jada's storage box will be 49.

A- The average rate of change of g(x) over the interval [-2, 2] is 4, B- the instantaneous rates of change at the endpoints are different from the average rate of change over the interval.

A) To find the average rate of change of the function g(x) over the interval [-2, 2], we need to compute the difference quotient:

average rate of change = [g(2) - g(-2)] / [2 - (-2)]

First, we find the values of the function at the endpoints of the interval:

g(-2) = \(-2^{3}\) - 6 = -14

g(2) = \(2^{3}\) - 6 = 2

Substituting these values into the

average rate of change = (2 - (-14)) / (2 - (-2)) = 16 / 4 = 4

Therefore, the average rate of change of g(x) over the interval [-2, 2] is 4.

B) To compare this rate with the instantaneous rates of change at the endpoints of the interval, we need to find the derivatives of the function at x=-2 and x=2 using the power rule of differentiation:

g'(x) = 3\(x^{2}\)

g'(-2) = 3\(-2^{2}\) = 12

g'(2)  = 12

The instantaneous rate of change at x=-2 is 12, and the instantaneous rate of change at x=2 is also 12. These values are equal to the average rate of change over the interval [-2, 2], which is 4.

This means that the function g(x) is not a linear function over the interval [-2, 2], and the instantaneous rates of change at the endpoints are different from the average rate of change over the interval.

Answer:

  24.98 units

Step-by-step explanation:

You want the perimeter of triangle ABC with vertices A(-5, 4), B(1, -2), and C(3,6).

The distance between two vertices can be found using the formula ...

  d = √((x2 -x1)² +(y2 -y1)²)

The  distance between A and B is ...

  d = √((1 -(-5))² +(-2 -4)²) = √(6² +(-6)²) = 6√2 ≈ 8.485

The attached spreadsheet performs the same calculation on all the pairs of points. (The distance from each point to the one below it is listed.)

The perimeter of the triangle is the sum of the segment lengths. That is also shown in the spreadsheet.

  P = AB +BC +CA

  P = 8.485 +8.246 +8.246 ≈ 24.98

The perimeter of triangle ABC is about 24.98 units.

Answer:

a) 896 ways

c) 910 ways

Step-by-step explanation:

The question is a combination problem since it has to do with selection. In combination, if r object is selected from a pool of n objects, this can be done in nCr ways.

nCr = n!/(n-r)!r!

If from a group of 8 women and 6 men, a committee consisting of 3 men and 3 women is to be formed, we need to first calculate the total committee formed without any condition.

8C3 × 6C3

= 8!/5!3! × 6!/3!3!

= 8×7×6×5!/5!×6 × 6×5×4×3!/3!×6

= 56×20

= 1120ways

Now if;

a) two of the men refuse to serve together.

Since two men refuse to serve together, we will select 1 man from remaining 4 men since two has already been selected then select 3 from 8 women as shown.

4C1×8C3

= 4×56

= 224ways

Number of ways this can be done will be 1120-224 = 896ways

b) 1 man and 1 woman refuse to serve together

We need to choose 2 men from remaining 5 and 2 women from the rest of the men which is 7 as shown:

= (8-1)C(3-1) × (6-1)C(3-1)

= 7C2 × 5C2

= 7!/5!2! × 5!/3!2!

= 7×6×5!/5!×2 × 5×4×3!/3!×2

= 21×10

= 210ways

The number of ways this can be done will be 1120-210 = 910ways

Step-by-step explanation:

let the 2 numbers be x and x + 4 as their deference is 4.

their sum = 50

now,

→ x + x + 4 = 50

→ 2x + 4 = 50

→ 2x = 50 - 4 = 46

→ x = 46/2 = 23

therefore two numbers are,

x = 23

x + 4 = 23 + 4 = 27

hope this answer helps you dear...take care and may u have a great day ahead!

Step-by-step explanation:

x + y = 50

x - y = 4

x = y + 4

let's use that as substitute in the first equation

y + 4 + y = 50

2y = 46

y = 46/2 = 23

=>

x = y + 4 = 23 + 4 = 27

the 2 numbers are 23 and 27.

The value of a and b are; 4.8 and 10.8 respectively.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

We have been given a figure which shows that;

Let x, y z, and u lines are parallel.

Therefore, by using proportion we can say that

a/ 12 = 4/ 10

thus, a = 4/ 10 (12)

a =2(12)/ 5

a = 24/5

a = 4.8

Now, 12/b = 10/8

b = 12 (8/10)

b = 6(8)/ 5

b  54/5

b = 10.8

Hence, tha value of a and b are; 4.8 and 10.8 respectively.

The counterclockwise circulation around c is 12 and the outward flux through c is zero.

Green's theorem is a useful tool for calculating the circulation and flux of a vector field around a closed curve in two-dimensional space.

In this case,

we have a field f=(7x−4y)i+(9y−4x)j and

a square curve c bounded by x=0, x=4, y=0, y=4.

To find the counterclockwise circulation, we can use the line integral of f along c, which is equal to the double integral of the curl of f over the region enclosed by c.

The curl of f is given by (0,0,3), so the line integral evaluates to 12.

To find the outward flux, we can use the double integral of the divergence of f over the same region, which is equal to zero since the divergence of f is also zero.

Answer: Let's represent the value of car 1 as x. Then, the value of car 2 is 3/4 of x, and the value of car 3 is 4/5 of the value of car 2.

So, we can write the following equations:

x = (3/4) * y

y = (4/5) * z

Where y is the value of car 2, and z is the value of car 3.

Adding all the values, we have:

x + y + z = 1115900

We can substitute the values of y and z in terms of x:

x + (3/4) * x + (4/5) * (3/4) * x = 1115900

Simplifying the expression on the left side, we get:

7/4 * x = 1115900

Finally, dividing both sides by 7/4, we get:

x = 359900

So, the value of car 1 is $359900, the value of car 2 is (3/4) * x = (3/4) * 359900 = 269925, and the value of car 3 is (4/5) * (3/4) * x = (4/5) * (3/4) * 359900 = 213140.

Step-by-step explanation:

Answer: the value of car 1 is $467125, the value of car 2 is $623033.33, and the value of car 3 is $350937.5.

Step-by-step explanation:

Let's call the value of car 1 "x".

From the first ratio, we know that the value of car 2 is 4/3 times greater than the value of car 1, and the value of car 3 is 3/4 times greater than the value of car 1.

So, the value of car 2 is 4/3 * x, and the value of car 3 is 3/4 * x.

From the second ratio, we know that the value of car 2 is 8/5 times greater than the value of car 3.

So, the value of car 2 is 8/5 * (3/4 * x) = 6/5 * x.

The total value of all three cars is $1115900, so we can set up an equation to solve for x:

x + 4/3 * x + 3/4 * x = 1115900

Expanding and simplifying the right side:

x + 4/3 * x + 3/4 * x = 1115900

8/3 * x = 1115900

x = 1115900 * 3 / 8

x = 467125

So, the value of car 1 is $467125, the value of car 2 is $623033.33, and the value of car 3 is $350937.5.

This polynomial function has four possible rational zeros (2, 3, 5, and 7) but no actual rational zeros since these values are all prime numbers.

To write a polynomial function that has four possible rational zeros but no actual rational zeros,

we can use the Rational Root Theorem.

The theorem states that if a polynomial has a rational root (zero), it must be of the form p/q, where p is a factor of the constant term and q is a factor of the leading coefficient.

Since we want four possible rational zeros but no actual rational zeros, we can use a constant term that is not divisible by any integers and a leading coefficient that is not divisible by any integers except

1. For example, we can use the constant term of 150 and the leading coefficient of 1.

The polynomial function that satisfies these conditions is:

f(x) = (x - p1)(x - p2)(x - p3)(x - p4)

Where p1, p2, p3, and p4 are four distinct prime numbers.

By using distinct prime numbers as the possible zeros, we ensure that there are no actual rational zeros.

For example, let's use p1 = 2, p2 = 3, p3 = 5, and p4 = 7:

f(x) = (x - 2)(x - 3)(x - 5)(x - 7)

This polynomial function has four possible rational zeros (2, 3, 5, and 7) but no actual rational zeros since these values are all prime numbers.

The mode best represents the set of data: red, blue, red, yellow, red, green, black, red, white, red. The mode is a statistical measure that represents the most frequently occurring value or values in a dataset.

The mode is the measure of center that represents the most frequently occurring value in a dataset. In this case, the color "red" appears most frequently, occurring 6 times out of the 11 data points. Therefore, the mode of the dataset is "red."

The mean, on the other hand, calculates the average value by summing all the data points and dividing by the total number of data points. The mean can be influenced by extreme values or outliers, which may not accurately represent the overall data.

The median is the middle value when the data is arranged in ascending or descending order. In this case, since there are 11 data points, the median would be the sixth value. However, there is no clear middle value as there are multiple occurrences of "red" in the dataset.

Hence, the mode, representing the most frequently occurring value, is the measure of center that best represents this set of data.

The particular solution is: y(x) = -9e^(-0.6x) To solve the separable differential equation dy/dx = -0.6y, we need to separate the variables by dividing both sides by y and dx:

1/y dy = -0.6 dx

Then, we integrate both sides:

ln|y| = -0.6x + C

where C is the constant of integration. To find the particular solution satisfying the initial condition y(0) = -9, we substitute x = 0 and y = -9 into the above equation:

ln|-9| = -0.6(0) + C

ln 9 = C

Therefore, the particular solution is:

ln|y| = -0.6x + ln 9

|y| = e^(ln 9) e^(-0.6x)

|y| = 9 e^(-0.6x)

Since y(0) = -9, we take the negative sign for the absolute value of y:

y(x) = -9 e^(-0.6x)

Therefore, the particular solution satisfying the initial condition y(0) = -9 is y(x) = -9 e^(-0.6x).
