The weight of Lucy's dog, written in expanded notation, is 9 kilograms and 0.75 kilograms.

Expanded notation is a way of writing a number as the sum of each digit multiplied by its place value. In this case, the number is 9.75. The digit 9 is in the tens place, so it represents 9 tens or 90. The digit 7 is in the ones place, so it represents 7 ones or 7.

The digit 5 is in the tenths place, so it represents 5 tenths or 0.5. The digit 7 is in the hundredths place, so it represents 7 hundredths or 0.07. Therefore, the weight of Lucy's dog in expanded notation is 90 kilograms plus 7 kilograms plus 0.5 kilograms plus 0.07 kilograms, which simplifies to 9 kilograms and 0.75 kilograms.

Mathematically, we can represent the given number as 9.75 = 9 x 10 + 7 x 1 + 5 x 0.1 + 7 x 0.01 = 90 + 7 + 0.5 + 0.07 = 9.57. Thus, the weight of Lucy's dog written in expanded notation is 9 kilograms and 0.75 kilograms.

We fail to reject the null hypothesis that the temperature level has no effect on the mean yield process.

Summary of Result:

Source | SS | df | MS | F | p-value

Treatment | 118.2 | 2 | 59.1 | 2.94 | 0.095

Error | 241.0 | 12 | 20.1 | |

Total | 359.2 | 14 | | |

To construct an analysis of variance (ANOVA) table and test whether the temperature level has an effect on the mean yield process, we need to perform the following steps:

Step 1: Calculate the total sum of squares (SST), the treatment sum of squares (SSTR), and the error sum of squares (SSE).

SST = ΣΣ(yij - ȳ)^2 = 359.2

where yij is the yield of the ith batch at the jth temperature level and ȳ is the overall mean yield.

SSTR = Σ(nj(ȳj - ȳ)^2) = 118.2

where nj is the number of batches produced at the jth temperature level, ȳj is the mean yield at the jth temperature level, and ȳ is the overall mean yield.

SSE = SST - SSTR = 241.0

Step 2: Calculate the degrees of freedom (df) for SST, SSTR, and SSE.

df(Total) = N - 1 = 14

where N is the total number of observations.

df(Treatment) = k - 1 = 2

where k is the number of treatment levels.

df(Error) = df(Total) - df(Treatment) = 12

Step 3: Calculate the mean square (MS) for SSTR and SSE.

MS(Treatment) = SSTR / df(Treatment) = 59.1

MS(Error) = SSE / df(Error) = 20.1

Step 4: Calculate the F-statistic.

F = MS(Treatment) / MS(Error) = 2.94

Step 5: Determine the critical value of F for a 0.05 level of significance with df(Treatment) = 2 and df(Error) = 12.

From a table of F-distributions, the critical value of F is 3.89.

Step 6: Compare the F-statistic to the critical value of F and make a decision.

Since 2.94 < 3.89, we fail to reject the null hypothesis that the temperature level has no effect on the mean yield process. In other words, we do not have sufficient evidence to conclude that there is a difference in mean yield among the three temperature levels.

Step 7: Summarize the results in an ANOVA table.

Source | SS | df | MS | F | p-value

Treatment | 118.2 | 2 | 59.1 | 2.94 | 0.095

Error | 241.0 | 12 | 20.1 | |

Total | 359.2 | 14 | | |

Note: The p-value is calculated as P(F > 2.94) = 0.095, which is greater than the significance level of 0.05. Therefore, we do not reject the null hypothesis.

Answer: 8

Hence, the required value of the line integral is\($\boxed{-84550}$\).

The given line integral is \($\int_{C}xyz ds$\), where the given curve C is \($x=8\sin t$, $y=t$, $z=-8\cos t$, $0\leq t\leq \pi$\).

Formula to evaluate line integral:\($$\int_{C}f(x,y,z)ds = \int_{a}^{b}f(x(t),y(t),z(t))\sqrt{\left(\frac{dx}{dt}\right)^2+\left(\frac{dy}{dt}\right)^2+\left(\frac{dz}{dt}\right)^2} dt$$Here, $f(x,y,z) = xyz$, $x(t)=8\sin t$, $y(t)=t$, $z(t)=-8\cos t$, $a=0$, $b=\pi$.\)

Hence, we have\($$\begin{aligned}\int_{C}xyz ds &= \int_{0}^{\pi} (8\sin t)(t)(-8\cos t)\sqrt{\left(\frac{dx}{dt}\right)^2+\left(\frac{dy}{dt}\right)^2+\left(\frac{dz}{dt}\right)^2} dt \\ &= \int_{0}^{\pi} (-64\sin t\cos t)(t)\sqrt{(8\cos t)^2+1^2+(-8\sin t)^2} dt \\ &= -64\int_{0}^{\pi} t\sin t\cos t\sqrt{64\cos^2t+64\sin^2t+1} dt\end{aligned}$$Let $u=64\cos^2t+64\sin^2t+1=65$, $du = 0$. When $t=0$, $u=65$, and when $t=\pi$, $u=65$\)

Hence, we have\($$\begin{aligned}& \int_{C}xyz ds = -64\int_{0}^{65} \left(\frac{t}{2}\right)\sqrt{u}\left(\frac{du}{32}\right) \\ &= -2\int_{0}^{65} t\sqrt{u}\ du \\ &= -2\left[\frac{2}{5}u^{\frac{5}{2}}\right]_{0}^{65} \\ &= -\frac{2}{5}(65)^{\frac{5}{2}} \\ &= -\frac{2}{5}(65)(65)^2 \\ &= \boxed{-84550}\end{aligned}$$\)

Monica worked 56 hours of overtime in the last 3 weeks.

Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future.

To start, we need to find Monica's standard weekly gross pay, before tax, since we know she saves 2/25 of this amount each week. We can set up an equation:

(2/25) × (standard weekly gross pay) × 16 = total savings

Simplifying this equation, we can cancel out the 16 and the 2 to get:

(1/25) × (standard weekly gross pay) × 8 = total savings

Dividing both sides by 8, we get:

(1/25) × (standard weekly gross pay) = total savings ÷ 8

We can substitute in the values we know:

total savings ÷ 8 = (1053 × (1-0.28)) ÷ 25

total savings ÷ 8 = $29.97

total savings = $239.76

So Monica saved $239.76 over the 16 weeks.

Next, we can calculate how much Monica earned from overtime. We know she worked 2 hours of overtime per week for the first 8 weeks and 3 hours of overtime per week for the next 5 weeks (weeks 9-13). That's a total of:

(2 hours/week) × 8 weeks + (3 hours/week) × 5 weeks = 26 hours

We also know she worked some overtime in the last 3 weeks, but we don't know how much. Let's call the number of hours she worked in the last 3 weeks "x". Then the total number of overtime hours she worked is:

26 + x

Monica earns $75 per overtime hour before tax. After tax, she earns:

$75 × (1-0.28) = $54 per overtime hour

If Monica spends some of her overtime pay and saves the rest in a 1:5 ratio, that means for every $6 she earns, she saves $5 and spends $1. So the amount she saves from her overtime is:

$54 × (5/6) = $45 per overtime hour

Now we can set up an equation to find "x", the number of overtime hours Monica worked in the last 3 weeks:

$45 × x = 3262.63 SG - $239.76

We need to convert the Singapore dollars to NZ dollars, since that's the currency Monica earned in:

3262.63 SG × $0.8411 NZ/SG = $2743.48 NZ

Substituting this value in, we get:

$45 × x = $2743.48 - $239.76

Simplifying:

$45 × x = $2503.72

Dividing both sides by $45, we get:

x = 55.64 hours

Rounded to the nearest hour, Monica worked 56 hours of overtime in the last 3 weeks.

The number of hours for the tortoise to walk 1 mile will be 1.5 hours.

Speed:

Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration. The pie divides the dimension of distance by time. The SI unit of speed is meter per second (m/s), but the most common unit of speed in everyday use is kilometer per hour (km/h), or in the US and UK United, the mile per hour (mph). air And for sea travel, knots are commonly used.

We know that the speed formula

Speed = Distance/Time

A tortoise takes 1 1/4​ hours to walk 5/6 miles.

Convert the mixed fraction number into a decimal number.

1 ¹/₄ = 1.25 hours

Then the speed of the tortoise will be calculated as,

⇒ Speed = (5/6) / 1.25

⇒ Speed = 0.667 miles per hour

The number of hours for the tortoise to walk 1 mile will be calculated as,

⇒ T = 1 / 0.667

⇒ T= 1.5 hours

The number of hours for the tortoise to walk 1 mile will be 1.5 hours.

The probability of winning the car without replacement is 1 in 3,276. and the probability of winning the car with replacement is 27 in 21,952

a. Without replacement of car balls,

The probability of selecting a "win a car" ball on the first try is 3/28. Since we did not replace the selected ball, there are now 2 "win a car" balls left out of a total of 27 balls. So, the probability of selecting a "win a car" ball on the second try is 2/27. Similarly, the probability of selecting a "win a car" ball on the third try is 1/26.

The overall probability of selecting 3 "win a car" balls in a row without replacement can be calculated by multiplying the individual probabilities of each selection:

P(3 "win a car" balls in a row without replacement) = (3/28) x (2/27) x (1/26) = 1/3276

So the probability of winning the car without replacement is 1 in 3,276.

b. With replacement of car balls:

If the "win a car" balls are replaced after each draw, the probability of selecting a "win a car" ball on each draw is always 3/28.

Therefore, the overall probability of selecting 3 "win a car" balls in a row with replacement can be calculated by multiplying the individual probabilities of each selection:

P(3 "win a car" balls in a row with replacement) = (3/28) x (3/28) x (3/28) = 27/21952

So the probability of winning the car with replacement is 27 in 21,952

Step-by-step explanation:

Jessie will cover a distance of about 486 yards.

The distance that Jessie will ride around the circular track can be calculated as the circumference of the circle.

The formula for the circumference of a circle is:

C = 2πr

Where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.

In this case, the radius of the circle is 25.8 yards.

We can substitute that into the formula and simplify:

C = 2πr

C = 2 × 3.14 × (25.8)

C = 162.024 yds

Since the circumference of the circular track is approximately 162.024 yards.

If Jessie rides around the track 3 times, the total distance she will ride is:

3 × 162.024 = 486 yards.

Therefore, option D) 486 yards is the correct answer.
