Answer:

$2.75

Step-by-step explanation:

We know that the random persons total was $5.50. To figure out how much one loaf of bread costs we must first, divide $5.50 by 2. We get 2.75. Then, to double check our answer we multiply that by 3 to get 8.25. We know that Micah' s total was $9.00. 9 minus 8.25 equals 0.75.

That price is very reasonable, for a jug of milk, so we know that $2.75 is the answer.

Substituting y = x + cos(x) into y" - 2y' + 5y results in 5x - 2 + 4cos(x) + 2sin(x), verifying the equation.

To verify that the function y = x + cos(x) satisfies the equation y" - 2y' + 5y = 5x - 2 + 4cos(x) + 2sin(x), we need to differentiate y twice and substitute it into the equation.

First, find the first derivative of y:

y' = 1 - sin(x)

Next, find the second derivative of y:

y" = -cos(x)

Now, substitute y, y', and y" into the equation:

-cos(x) - 2(1 - sin(x)) + 5(x + cos(x)) = 5x - 2 + 4cos(x) + 2sin(x)

Simplifying both sides of the equation:

-3cos(x) + 2sin(x) + 5x - 2 = 5x - 2 + 4cos(x) + 2sin(x)

The equation holds true, verifying that y = x + cos(x) satisfies the given differential equation.

To find the general solution to the equation, we can solve it directly by rearranging the terms and integrating them. However, since the equation is already satisfied by y = x + cos(x), this function is the general solution.

The given probability of having six girls in a six-child family is 0.015625. To determine the method used to compute this probability, we need to analyze the information provided.

The Classical method is based on theoretical assumptions and probabilities calculated using mathematical principles. It assumes equally likely outcomes and relies on counting favorable outcomes over the total number of possible outcomes.

The Empirical method involves gathering data from observations or experiments to estimate probabilities. It relies on observed frequencies and relative frequencies to compute probabilities. However, the given probability does not suggest a sample or data collection, making it unlikely that the Empirical method was used.

The Subjective method involves assigning probabilities based on personal judgment or opinions. Individuals subjectively evaluate the likelihood of an event based on their own beliefs or knowledge.

To determine the Mean Absolute Deviation (MAD), we need the actual sales data and the forecasted values. Since the actual sales data is not provided, it is not possible to calculate the MAD accurately.

MAD is calculated by taking the average of the absolute differences between the forecasted values and the actual values. Without the actual sales data, we cannot compute the absolute differences and find the MAD.

To calculate the MAD, you will need the actual sales data and the corresponding forecasted values for each day. Then, you can calculate the absolute differences between the actual and forecasted values, take their average, and round the result to two decimal places to obtain the MAD.

The problem asks us to find the length of the curve R(t) = 2 cos(2t) i - 2 sin(2t)j + 4tk over the interval (2,5].

To find the length of the curve, we need to use the formula L = ∫(a,b)|R′(t)|dt, where a and b are the bounds of the interval, and R′(t) is the derivative of R(t).

To find the derivative of R(t), we differentiate each component of R(t) separately with respect to t.

For the first component, we use the chain rule and obtain d/dt(2 cos(2t)) = -4 sin(2t).

For the second component, we use the chain rule again and obtain d/dt(-2 sin(2t)) = -4 cos(2t).

For the third component, we simply take the derivative and obtain d/dt(4t) = 4.

Therefore, we can write R′(t) = (-4 sin(2t)) i - (4 cos(2t)) j + 4k.

To find the length of the curve, we take the magnitude of the derivative |R′(t)| = √(16 sin²(2t) + 16 cos²(2t) + 16) = 4√2. We then integrate |R′(t)| from t = 2 to t = 5 using the formula L = ∫2→5 |R′(t)|dt.

This gives us L = ∫2→5 4√2 dt = 4√2 ∫2→5 dt = 4√2 (5 - 2) = 12√2.Therefore, the length of the curve R(t) over the interval (2,5] is 12√2.

The length of the curve R(t) = 2 cos(2t) i - 2 sin(2t)j + 4tk over the interval (2,5] is 12. We found this by using the formula L = ∫(a,b)|R′(t)|dt, where a and b are the bounds of the interval, and R′(t) is the derivative of R(t). We took the derivative of R(t) and found that R′(t) = (-4 sin(2t)) i - (4 cos(2t)) j + 4k. We then took the magnitude of R′(t) and integrated it over the interval (2,5] to obtain the length of the curve, which is 12.

The independent events are illustrations of probability, and the value of P (b) is 0.60

To determine the value of P (b):

The given parameters are:

P (a) = 0.20

P (a and b) = 0.12

The two events a and b are independent, if

P (a and b) = P (a) × P (b)

So, we have:

0.20 × P (b) = 0.12

Divide both sides by 0.20

That is,

( 0.20 x P (b) ) ÷ 0.20 = 0.12 ÷ 0.20 = 0.60

Hence, the value of P (b) is 0.60

The vector function r(t) = (7 cost(t) ) i + (7 sin(t) ) i + (49 cos(t) · sin(t) ) i

Define Vector function

A vector-valued function, also referred to as a vector function, is a mathematical function of one or more variables whose range is a set of multidimensional vectors or infinite-dimensional vectors.

We know, vector function r(t) is represented as,

r(t) = x(t) i + y(t) j + z(t) k

Given that,

x² + y² = 49

z = xy

Take the equation,

x² + y² = 49

we know, 7² = 49

x² + y² = 7²

Also we can write as,

x² + y² = 7² * 1

In trigonometry, we know

cos²(t) + sin²(t) = 1

Now, substitute for the 1

x² + y² = 7² * ( cos²(t) + sin²(t) )

x² + y² = 7² * cos²(t) + 7² * sin²(t)

By law of indices,

x² + y² = ( 7 * cos(t) )² + ( 7 * sin(t) )²

or,

x² + y² = ( 7 cos(t) )² + ( 7 sin(t) )²

By comparison, we get

x² = ( 7 cos(t) )²       and      y² =  ( 7 sin(t) )²

Remove the squares,

x = 7 cos(t)             and      y = 7 sin(t)

Also we have,

z = xy

put the values of x and y we get,

z = 7 cos(t) * 7 sin(t)

z = 49 cos(t) · sin(t)

Now, substitute the values in

r(t) = x(t) i + y(t) j + z(t) k

r(t) = (7 cost(t) ) i + (7 sin(t) ) i + (49 cos(t) · sin(t) ) i

Hence, the vector function r(t) = (7 cost(t) ) i + (7 sin(t) ) i + (49 cos(t) · sin(t) ) i

Answer:

Step-by-step explanation:

The reliability coefficient determined by the correlation between scores on half of the items on a measure with scores on the other half of the measure is called split-half reliability.

This method is commonly used to estimate the internal consistency of a measurement instrument. The measure is divided into two halves, and the scores on one half are compared to the scores on the other half using correlation analysis.

A high correlation indicates that the two halves of the measure are consistent and reliable in measuring the same construct. However, split-half reliability assumes that the two halves of the measure are equivalent and that the items are interchangeable, which may not always be the case. Other methods, such as Cronbach's alpha, may be used to assess reliability more accurately.

Step-by-step explanation:

\(f(x) = -2x^5 + x^4 + x^2 -2\)

\(f(-3) = -2(-3)^5 + (-3)^4 + (-3)^2 -2\)

\(\implies f(-3) = -2(-243) + 81 + 9 -2\)

\(\implies f(-3) = 574\)

\(f(4) = -2(4)^5 + (4)^4 + (4)^2 -2\)
