The decimal that Juanita can use to update her report is 1.6.

A decimal is a number with a whole and a fractional part. Decimal numbers are between integers and represent numerical value for whole plus some fraction of a whole.

The decimal numeral system is the most widely used system for representing both integer and non-integer numbers. It is the Hindu-Arabic numeral system's extension to non-integer numbers. Decimal notation refers to the method of representing numbers in the decimal system.

In this case, the the pitcher threw a total of 384 pitches and used a fastball 240 times. The decimal will be:

The probability distribution for the random variables X (number of pages with moderate graphics) and Y (number of pages with high graphics) can be represented as follows:

P(X = x, Y = y) = (30Cx * 10Cy) / (100C4)

In this scenario, we have a hypergeometric distribution because we are sampling without replacement from a finite population (100 pages).

The probability of selecting x pages with moderate graphics (out of 30) and y pages with high graphics (out of 10) from the sample can be calculated using the hypergeometric probability formula. The numerator represents the number of favorable outcomes (combinations of selecting x moderate pages and y high pages) and the denominator represents the total number of possible outcomes (combinations of selecting any 4 pages).

Using the combination formula, 30Cx represents the number of ways to choose x out of 30 moderate pages, and 10Cy represents the number of ways to choose y out of 10 high pages. The denominator, 100C4, represents the total number of ways to choose any 4 pages out of 100.

The probability distribution can be used to calculate the probabilities of different combinations of moderate and high graphics pages occurring in a sample of four pages selected from the small-business website. This information can be helpful in understanding the likelihood of certain graphics content being present in the sample and can aid in decision-making or analysis related to the website's content.

Answer:

RM =20

Step-by-step explanation:

Find the diagram of the parallelogram attached

From the diagram, GP = PA

8x = 2x+18

8x - 2x = 18

6x = 18

x = 18/6

x = 3

Since RM = 2RP

RM = 2(x+7)

RM = 2(3+7)

RM = 2(10)

RM =20

Hence the length of RM is 20

The original cost of the tablet is $70.89 in the given algebraic equation.

A mathematical claim containing two equated algebraic expressions is known as an algebraic equation. When P and Q are polynomials, an algebraic equation has the general form P = 0 or P = Q. The term "multivariate equation" refers to an algebraic equation that has more than one variable.

Univariate equations are algebraic equations that only have one variable. Equations in algebra are balanced by definition. Due to this, the right and left sides of the equation will be equal.

Let the original cost be  x

then

15/100 = 24.99.x

x =  166.6

237.49 - 166.6

= $70.89

Thus, the original cost of the tablet is $70.89 in the given algebraic equations.

Answer:

60

Step-by-step explanation:

Let the total number of marbles in the bag be x

x - x/3 - x/2 - x/8 = 20

24x/24 - 8x/24 - 12x/24 - 3x/24 = 20

(24x - 8x - 12x - 3x) /24 = 20

x = 20 x 24

x = 480

no of purple marbles = 480 x 1/8

                                  = 480/8

Betty takes 6 hours to paint a house alone, that indicates she can paint 1/6 of the house in 1 hour then Karen working alone will paint a house in 3 hours.

Since Betty takes 6 hours to paint a house alone, that indicates she can paint 1/6 of the house in 1 hour.

Karen can even paint 1/x in 1 hour

Both of them will paint the house in 3/2 hours.

We then add them together which gives:

1/6 + 1/x = 3/2x

The lowest common multiple is 6x

1x/6x + 6/6x = 9/6x

We then leave out the denominators

1x + 6 = 9

simplifying the above equation, we get

x = 9 - 6

x = 3

Therefore, the value of x = 3.

Answer:

D

Step-by-step explanation:

The y-coordinate will be the average of 5 and -2 which is 3/2. This eliminates options A and B. C doesn't make sense because the x-coordinate (which is -7) of the midpoint can't be larger or smaller than the x-coordinates of the endpoints, so that means that the answer is D.

The area between z=1.1 and z=2.1 is approximately 0.982 - 0.864 = 0.118, rounded to three decimal places.

To find the area below z=1.04 for an Upper N(0,1) density, you will need to use the standard normal distribution table or a calculator with a z-table function. Here are the steps:

1. Locate the value of z=1.04 in the table or use the calculator's function.
2. Find the corresponding area value (which represents the probability or percentage of values below z=1.04).

The area below z=1.04 is approximately 0.851, rounded to three decimal places.

(b) To find the area above z=-1.4 for an Upper N(0,1) density, follow these steps:

1. Locate the value of z=-1.4 in the table or use the calculator's function.
2. Find the corresponding area value.
3. Since we need the area above z=-1.4, subtract the area value found in step 2 from 1.

The area above z=-1.4 is approximately 1 - 0.0808 = 0.919, rounded to three decimal places.

(c) To find the area between z=1.1 and z=2.1 for an Upper N(0,1) density, follow these steps:

1. Locate the values of z=1.1 and z=2.1 in the table or use the calculator's function.
2. Find the corresponding area values for both z=1.1 and z=2.1.
3. Subtract the area value of z=1.1 from the area value of z=2.1 to find the area between them.

The area between z=1.1 and z=2.1 is approximately 0.982 - 0.864 = 0.118, rounded to three decimal places.

\(x+y=-7\)

Their product can be written mathematically as

⇒ x×y=6

\(xy=-6\)

As a results you can see that we have a system of equation that we have to solve and we can solve it by substitution

let us derive the third equation from the first equation by making x the subject of the equation

As a results we have x=-7-y

Now let us substitute the equation to the second equation .

\((-7-y)(y)=6\\-7y-y^{2} =6\\-y^{2} -7y-6=0\\-(y^{2} +7y+6)=0\\y^{2} +7y+6=0\\(y+6)(y+1)=0\\y+6=0\\\\or\\y+1=0\\y=-6\\\\or \\y=-1\)

when y =-1

x=-7-(-1)

x=-7+1

⇒x=-6

When y=-6

x=-7-(-6)

After the 10th iteration, the estimated value of the root obtained by the bisection method is approximately 0.517. Option B

To solve the equation cos(x) - x * e = 0 in the interval [0, 1] using the bisection method, we start by checking the function values at the endpoints of the interval.

For x = 0:

cos(0) - 0 * e = 1 - 0 = 1

For x = 1:

cos(1) - 1 * e ≈ 0.54 - 2.72 ≈ -2.18

Since the function values at the endpoints have opposite signs, we can apply the bisection method to find the root within the interval.

The bisection method involves repeatedly dividing the interval in half and checking the function value at the midpoint until a sufficiently accurate approximation is obtained. In this case, we will perform 10 iterations.

After the 10th iteration, the estimated value of the root obtained by the bisection method is approximately 0.517.

Therefore, the correct answer is OB) 0.517.

The partial fraction decomposition of the function f(x) = x^4 - x^5 + 5x^3 can be written in the form:
f(x) = A/(x-a) + B/(x-b) + C/(x-c) + D/(x-d) + E/(x-e),
where A, B, C, D, and E are coefficients to be determined, and a, b, c, d, and e are the roots of the polynomial.

To find the partial fraction decomposition, we need to factorize the denominator of the function into linear factors. In this case, the denominator is x^4 - x^5 + 5x^3.

Step 1: Factorize the denominator
x^4 - x^5 + 5x^3 can be factored as x^3(x-1)(x^2 + 5).

Step 2: Set up the decomposition
Now that we have the factors of the denominator, we can set up the partial fraction decomposition:
f(x) = A/(x-a) + B/(x-b) + C/(x-c) + D/(x-d) + E/(x-e).

Step 3: Determine the coefficients
To determine the coefficients A, B, C, D, and E, we need to find the values of a, b, c, d, and e. These values are the roots of the polynomial x^4 - x^5 + 5x^3.
The roots can be found by setting each factor equal to zero and solving for x:
x^3 = 0 → x = 0 (a root of multiplicity 3)
x - 1 = 0 → x = 1 (a root of multiplicity 1)
x^2 + 5 = 0 → x = ±√(-5) (complex roots)

Step 4: Substitute the roots into the decomposition

Substituting the roots into the partial fraction decomposition, we get:

f(x) = A/x + A/x^2 + A/x^3 + B/(x-1) + C/(x+√(-5)) + D/(x-√(-5)) + E.

Note: The coefficients A, B, C, D, and E are determined by solving a system of linear equations formed by equating the original function f(x) with the decomposition and evaluating at the different roots.
