Josh's paycheck can be calculated by finding three-fourths of the total amount he spent on the TV and then adding $100 to that amount. By subtracting this total from the cost of the TV, we can determine the value of his paycheck.

Let's assume Josh's paycheck is represented by the variable "P." According to the information given, Josh used one hundred dollars less than three-fourths of his paycheck to buy the new TV, which cost $488.

To find out how much Josh spent on the TV, we can set up an equation. Three-fourths of his paycheck is represented by (3/4)P, and since he spent $100 less than that amount, the equation becomes (3/4)P - $100 = $488.

To solve for P, we need to isolate the variable. Adding $100 to both sides of the equation, we have (3/4)P = $588. Next, we can multiply both sides of the equation by the reciprocal of (3/4), which is 4/3, to cancel out the fraction. This yields P = ($588) * (4/3) = $784.

Therefore, Josh's paycheck was $784.

Lucy has $7 less than Kristine and $5 more than Nina together, the three have $35. Lucy has $11.

Let's denote the amount of money that Kristine has as K, the amount of money that Lucy has as L, and the amount of money that Nina has as N.

According to the given information, we can form two equations:

Lucy has $7 less than Kristine: L = K - 7

Lucy has $5 more than Nina: L = N + 5

We also know that the three of them have a total of $35: K + L + N = 35

We can solve this system of equations to find the values of K, L, and N.

Substituting equation 1 into equation 3, we get:

K + (K - 7) + N = 35

2K - 7 + N = 35

Substituting equation 2 into the above equation, we get:

2K - 7 + (L - 5) = 35

2K + L - 12 = 35

Since Lucy has $7 less than Kristine (equation 1), we can substitute K - 7 for L in the above equation:

2K + (K - 7) - 12 = 35

3K - 19 = 35

Adding 19 to both sides:

3K = 54

Dividing both sides by 3:

K = 18

Now we can substitute the value of K into equation 1 to find L:

L = K - 7

L = 18 - 7

L = 11

Finally, we can find the value of N by substituting the values of K and L into equation 3:

K + L + N = 35

18 + 11 + N = 35

N = 35 - 18 - 11

N = 6

The Taylor polynomial T₅(x) is 0.99500416 and by use the Error Bound the maximum possible size of the error is 49943.1 × 10⁻⁷.

What is Taylor Series?

The Taylor series or Taylor expansion of a function in mathematics is the infinite sum of terms represented in terms of the function's derivatives at one particular point. The function and the sum of its Taylor series are roughly equivalent for the majority of typical functions at this point.

Taylor series or Taylor expansion:

Infinity ∑ (n = 0) fⁿ(a)/n! (x - a)ⁿ

Where,

n! = factorial of n

a = real or complex number

fⁿ(a) = nth derivative of function f evaluated at the point a.

As given function is,

f(x) = cosx, a = 0, x = 0.1

Taylor polynomial of degree 'n' for f(x) center a,

Tₙ(x) = f(a) + f'(a)(x - a) + f''(a)/2 (x - a)² + f'''(a)/3 (x - a)³ + ......+ fⁿ⁻¹(a)/(n - 1)! (x - a)ⁿ⁻¹ + fⁿ(a)/n! (x - a)ⁿ

Evaluate values as follows:

f(x) = cosx ⇒ f(0) = 1

f'(x) = -sinx ⇒ f'(0) = 0

f''(x) = -cosx ⇒ f''(0) = -1

f'''(x) = sinx ⇒ f'''(0) = 0

f⁴(x) = cosx ⇒ f⁴(0) = 1

f⁵(x) = -sinx ⇒ f⁵(0) = 0

Substitute obtained values in Taylor series,

T₅(x) = 1 + (0) (x - 0) + (-1)/2 (x - 0)² + 0 + 1/24(x - 0)⁴ + 0

T₅(x) = 1 -1/2x² + 1/24x⁴

At x = 0.1

T₅(0.1) = 1 -1/2(0.1)² + 1/24(0.1)⁴

T₅(0.1) = 1 - 0.005 + 4.16 × 10⁻⁶

T₅(0.1) = 0.99500416

Hence, the Taylor polynomial T₅(x) is 0.99500416.

Evaluate the maximum possible size of the error:

cos(0.1) = 0.99999847

T₅(0.1) = 0.99500416

Icos(0.1) - T₅(0.1)I = 0.99999847 - 0.99500416

Icos(0.1) - T₅(0.1)I = 0.00499431

Icos(0.1) - T₅(0.1)I = 49943.1 × 10⁻⁷.

Step-by-step explanation:

We know that 3/8 cup of brown sugar and 1/3 cup of white sugar are mixed together to make the sugar mixture.

From this sugar mixture, 1/4 cup is set aside for the crumb topping.

To find out how much sugar mixture is used to make the cake, we need to subtract the amount set aside for the crumb topping from the total sugar mixture.

We can start by converting the mixed unit of measurement (brown sugar in cups and white sugar in cups) to a single unit of measurement (cups)

3/8 cup of brown sugar + 1/3 cup of white sugar = (3/8)+(1/3) = 5/12 cup + 4/12 cup = 9/12 cup.

1/4 cup is set aside for the crumb topping.

So, the remaining sugar mixture used to make the cake is 9/12 cup - 1/4 cup = (9/12) - (1/4) = (9-3)/12 = 6/12 cup = 0.5 cup

The Maclaurin series of f(x) = (Hint: use the binomial series) |R₁(x)| <= (15/16)(x²)/3!for x in [-1/2,1/2]. The formula for binomial series is given as follows:\((1+x)^n = 1 + nx + n(n-1) x^2/2! + n(n-1)(n-2) x^3/3! +.... + n(n-1)(n-2)....(n-r+1) x^r/r! +....\)

The binomial series can also be written as:\((1+x)^n = Summation of [nCr x^r]\), where r ranges from 0 to infinity and nCr is the binomial coefficient of n and r.

So, we have the following expression:\((1+x^2)^1/2 =\)Summation of \([(1/2)(1/2-1)(1/2-2)...(1/2-r+1) x^2/r!] + ....\)

Now, we can substitute arcsin(x) = y into the Maclaurin series for \((1+x^2)^1/2\) and integrate both sides to get the Maclaurin series for arcsin(x).

So, we have the following expression: arcsin(x) = Summation of\([(1.3.5...(2n-1))/2.4.6...(2n)] x^(2n+1)/(2n+1) + ....\)

The first two terms in this series are\(x + x^3/6.\)

To find the error of the approximation using the first two terms in this series (arcsin x= x+) with xe [-1/2, 1/2], we can use Taylor's Inequality.

Taylor's Inequality states that the error of the approximation is bounded by the next term in the Taylor series, so we have:|Rn(x)| <=\(M(x-a)^(n+1)/(n+1)!\), where M is the maximum value of the (n+1)th derivative of f(x) on the interval [a,x].

Since we're using the first two terms in the series, n = 1, so we have:

|R₁(x)| <= \(M(x-a)^2/3!\) where M is the maximum value of the (n+1)th derivative of f(x) on the interval [-1/2,1/2].

The third derivative of arcsin(x) is given by: f'''(x) = \(15x/[(1-x^2)^2(4)] .\)

The maximum value of the third derivative on the interval [-1/2,1/2] is 15/16, which occurs at x = 1/2. So, we have:

M = 15/16 and a = 0.

Using these values, we have:|R₁(x)| <= (15/16)(x²)/3! for x in [-1/2,1/2].

Typically, an infant who is 24-hours-old would need to consume around 2-3 ounces of formula per feeding to meet their daily caloric needs on a 4-hour feeding schedule. However, it's important to note that every baby is different and may require more or less formula depending on their individual needs and growth.

To determine the recommended ounces of formula for a 24-hour-old infant on a 4-hour feeding schedule, we need to consider the infant's daily caloric needs. Here's a step-by-step explanation:
1. An average newborn infant requires around 100-120 calories per kilogram (2.2 pounds) of body weight per day.
2. Assuming an average newborn weight of 3.5 kg (7.7 lbs), the infant would need 350-420 calories per day (3.5 kg x 100-120 calories/kg).
3. Formula generally provides around 20 calories per ounce.
4. Divide the total daily caloric needs by the calories per ounce: 350-420 calories ÷ 20 calories/ounce = 17.5-21 ounces of formula per day.
5. Since the infant is on a 4-hour feeding schedule, they will have 6 feedings per day (24 hours ÷ 4 hours/feeding).
6. Divide the total daily ounces by the number of feedings: 17.5-21 ounces ÷ 6 feedings = 2.9-3.5 ounces per feeding.
So, a newborn infant who is 24-hours-old on a 4-hour feeding schedule should receive approximately 2.9-3.5 ounces of formula at each feeding to meet their daily caloric needs.

Dividing both sides by cos x

sin x/cos x < cos x/cos x

tan x < 1

x < \(tan^{-1}1\)

Since x is less than 45°, then one of the possible value of x can be 30° since 30° is less than 45° and 30° falls within the given range of values.

Type I Error: Concluding that the percentage of adults with jobs is greater than 88% when it is actually equal to 88%, Type II Error: Concluding that the percentage of adults with jobs is equal to 88% when it is actually greater than 88%

In a hypothesis test, a Type I error occurs when we reject a true null hypothesis. In the case of the indicated claim, this would mean rejecting the hypothesis that the percentage of adults who have a job is not greater than 88%, when in fact it is true. This would be a serious mistake as we would be making a false claim.

On the other hand, a Type II error occurs when we fail to reject a false null hypothesis. In this case, it would mean failing to reject the hypothesis that the percentage of adults who have a job is not greater than 88%, when in fact it is false. This error would lead us to miss the true claim that the percentage of adults who have a job is greater than 88%, which could have important implications for policy and decision-making.

Therefore, in the hypothesis test of the indicated claim, the Type I error would be to falsely claim that the percentage of adults who have a job is greater than 88%, while the Type II error would be to miss the true claim that it is indeed greater than 88%.

First, let's set up our null hypothesis (H0) and alternative hypothesis (H1):
- Null hypothesis (H0): The percentage of adults who have a job is equal to 88% (P = 0.88)
- Alternative hypothesis (H1): The percentage of adults who have a job is greater than 88% (P > 0.88)

Now, let's identify the Type I and Type II errors for this hypothesis test:

1. Type I Error: This occurs when we reject the null hypothesis (H0) when it is actually true. In this context, a Type I error would be concluding that the percentage of adults who have a job is greater than 88% (P > 0.88) when, in reality, it is equal to 88% (P = 0.88).

2. Type II Error: This occurs when we fail to reject the null hypothesis (H0) when it is actually false. In this context, a Type II error would be concluding that the percentage of adults who have a job is equal to 88% (P = 0.88) when, in reality, it is greater than 88% (P > 0.88).

The margin of error of the random selection is 0.20

The given parameters are:

\(n = 420\) --- the sample size

\(\sigma = 1.6\) --- the standard deviation

\(\bar x = 10\) --- the mean

\(\alpha = 99\%\) --- the confidence level.

The margin of error (E) is calculated as follows:

\(E = z \times \sqrt{\frac{\sigma^2}{n}}\)

So, we have:

\(E = z \times \sqrt{\frac{1.6^2}{420}}\)

\(E = z \times \sqrt{\frac{2.56}{420}}\)

The z-value for 99% confidence level is 2.576.

Substitute 2.576 for z

\(E = 2.576 \times \sqrt{\frac{2.56}{420}}\)

\(E = 2.576 \times \sqrt{0.006095}\)

Take square roots

\(E = 2.576 \times 0.0781\)

To find the confidence interval for estimating the population mean score, we can use the following formula:

CI = x ± z*(σ/√n)

Where:

x = sample mean score = 38.6

σ = population standard deviation (unknown)

n = sample size = 64

z = z-score for the desired confidence level, which is 1.645 for 90% confidence interval

First, we need to estimate the population standard deviation using the sample standard deviation:

s = 4.9

Next, we can plug in the values into the formula:

CI = 38.6 ± 1.645*(4.9/√64)

= 38.6 ± 1.645*(0.6125)

= 38.6 ± 1.008
