Answer:

a. 20 pieces

b. 20cm each

Step-by-step explanation:

a. 4*5=20

If he cut one of the ropes into 5 pieces, then you do the same to each of them. So that would be 5+5+5+5, which is 20.

b. 100/5=20cm

Using the question, we can assume that each rope is 1M, or 100cm. so instead of making 1meter split into 5 (which would be written as 1/5M) you instead do 100centimeters split into 5, which is 20cm each.

Step-by-step explanation:

Let the number be \(\overline{abc}=100a+10b+c\).

\(100a+10b+c=34a+34b+34c \\ \\ 66a-24b-33c=0 \\ \\ 22a-8b-11c=0\)

Taking the equation mod \(11\) yields \(-8b \equiv \pmod{11}\), meaning \(b=0\).

So, \(22a-11c=0 \implies c=2a\).

So, the only possibilites are \((a,c)=(1,2), (2,4),(3,6), (4,8)\).

Therefore, there are \(4\) such numbers.

The partial derivatives with respect to x and y, we obtain dz/dx = cos(x - y) and dz/dy = -cos(x - y), respectively. When dz/dx and dz/dy are both zero, the crests and troughs are aligned.

The given water wave function is graphed as z = 1 + sin(x - y) using Mathematica. The crests and troughs of the wave are aligned in the direction of zero change in the height function, which can be determined by analyzing the partial derivatives. The steepest descent from a crest to a trough corresponds to the direction perpendicular to the alignment of crests and troughs. These conclusions are consistent with the graph of the wave.

The water wave function z = 1 + sin(x - y) represents a snapshot of a frozen water wave. To graph this function using Mathematica, the x and y coordinates are assigned appropriate ranges, and the resulting z-values are plotted.

To determine the alignment of the crests and troughs, we examine the rate of change of the height function. Taking the partial derivatives with respect to x and y, we obtain dz/dx = cos(x - y) and dz/dy = -cos(x - y), respectively. When dz/dx and dz/dy are both zero, the crests and troughs are aligned. Setting dz/dx = 0 gives cos(x - y) = 0, which implies x - y = (2n + 1)π/2, where n is an integer. This equation represents lines in the xy-plane along which the crests and troughs are aligned.  

For the steepest descent from a crest to a trough, we need to find the direction of maximum decrease in the height function. This direction corresponds to the negative gradient of the height function, which can be obtained by taking the partial derivatives dz/dx and dz/dy and forming the vector (-dz/dx, -dz/dy). Simplifying this vector, we get (-cos(x - y), cos(x - y)), which represents the direction perpendicular to the alignment of crests and troughs.    

Upon examining the graph of the wave, we can observe that the lines of alignment for the crests and troughs match the lines where the height function has zero change, confirming our conclusion from part (b). Similarly, the direction of steepest descent from a crest to a trough, indicated by the negative gradient, aligns with the steepest downward slopes on the graph.

The sample is the part of the population that somebody wants to study. therefore, the sample is the 100 male students interviewed

The best point estimate for the mean monthly electric bill for all residents of the local apartment complex is $148.

Since we are given the mean monthly electric bill for a sample of 80 residents of the apartment complex, we can use this as an estimate for the mean monthly electric bill for the entire population of residents. This estimate is known as a point estimate because it represents a single numerical value that is used to estimate the population parameter.

In this case, the sample mean of $148 is the best point estimate for the mean monthly electric bill for all residents of the local apartment complex. This is because the sample mean is an unbiased estimator of the population mean and it minimizes the variance of the estimates.

It is important to note, however, that the accuracy of the point estimate depends on the representativeness of the sample. If the sample is not representative of the population, the point estimate may not accurately reflect the population parameter.

Therefore, the correct answer is $148.

The As Fed weight of the bale is 733.33 lbs and in  1 ton (2000 lbs) of that hay there would be  1740 lbs of DM.

You have a bale of hay that is 87% DM, and there is 638 lbs of DM in that bale. To find the As Fed weight of the bale, you can use the following formula:

As Fed weight = (DM weight) / (% DM)

Step 1: Convert the percentage to a decimal:
87% DM = 0.87

Step 2: Plug the values into the formula:
As Fed weight = (638 lbs) / (0.87)

Step 3: Calculate the As Fed weight:
As Fed weight ≈ 733.33 lbs

So, the As Fed weight of the bale is approximately 733.33 lbs.

Now, to find how many pounds of DM would be in 1 ton (2000 lbs) of that hay, you can use the following formula:

DM in 1 ton = (2000 lbs) * (% DM)

Step 1: We already have the percentage as a decimal (0.87).

Step 2: Plug the values into the formula:
DM in 1 ton = (2000 lbs) * (0.87)

Step 3: Calculate the DM in 1 ton:
DM in 1 ton = 1740 lbs

Therefore, there would be 1740 lbs of DM in 1 ton (2000 lbs) of that hay.

2 - 2 = 0

Now, let's find f(x) by plugging in the simplified expression:
f(x) = 0 - (2/x-2)
To find f'(2), we need to use the definition of the derivative:
f'(2) = lim h→0 [f(2+h) - f(2)]/h
Plugging in f(x), we get:
f'(2) = lim h→0 [0 - (2/(2+h)-2)]/h

Simplifying this expression using algebra, we get:
f'(2) = lim h→0 [-2/(h(h+2))]
Now, we use expression (5) on page 144 to simplify further:
f'(2) = lim g(x), where g(x) = -2/(x(x+2))
To find g(1), we simply plug in x=1:
g(1) = -2/(1(1+2))
g(1) = -2/3

Answer:

  a) 56.25 mph

  b) $1.59/lb

Step-by-step explanation:

The units of the "unit rate" tell you the math operation you need to perform.

Miles per hour (mi/h) is found by dividing miles by hours.

  (450 mi)/(8 h) = (450/8) mi/h = 56.25 mi/h

Dollars per pound ($/pound) is found by dividing dollars by pounds.

  ($7.95)/(5 pounds) = (7.95/5) $/pound = 1.59 $/pound

__

Additional comment

In the context of unit rates, "per" means "divided by."

What makes a rate a "unit rate" is the "1 unit" in the denominator. For miles per hour, the denominator is 1 hour. For dollars per pound, the denominator is 1 pound.

The volume of plaster Darla needs for the miniature stairs is 418³.

The volume is the space occupied by a three-dimensional object.

Volume is the product of the multiplication of length, width, and height.

We first calculate the total volume for this situation, assuming that the stairs have not cut portions.

Secondly, calculate the volume of the cut portions and subtract the result from the total volume to get the volume of the stairs, which represents the quantity of plaster required by Darla.

Length of the miniature stairs = 12 cm

Width of the miniature stairs = 11 cm

Height of the miniature stairs = 4 cm

The volume of the stairs with the cut portion = 528 cm³ (12 x 11 x 4)

The length of the cut portion of the stairs = 12 cm

The width of the cut portion of the stairs = 11 cm

The height of the cut portion of the stairs = 2 cm (4 - 2)

The volume of the cut portion of the stairs = 110 cm³ (11 x 5 x 2)

The volume of the stairs without the cut portion = 418 cm³ (528 - 120)

The total volume of plaster can also be computed separately as the volume of the larger object plus the volume of the smaller object.

418 cm³= (7 cm x 4 cm x 11 cm) + (5 cm x 2 cm x 11 cm)

= (308 cm³ + 110 cm³)

Thus, the quantity (volume) of plaster Darla needs is 418 cm³.

The probability of a patient scoring above 192 on the endurance test is approximately 40.90%. A patient at the 80th percentile receives a score of approximately 208.2.

a. To find the probability that a patient will score above 192, we need to use the Z-score formula. The Z-score measures the number of standard deviations a data point is from the mean. In this case, the formula is Z = (X - μ) / σ, where X is the score, μ is the mean, and σ is the standard deviation.

First, calculate the Z-score: Z = (192 - 185) / 30 = 7/30 ≈ 0.23.

Next, we need to find the probability of scoring above this Z-score. Using a Z-table or a calculator, we find that the probability is approximately 0.4090, or 40.90%.

b. To find the score that corresponds to the 80th percentile, we need to find the Z-score that has an area of 0.80 to the left. Using the Z-table or a calculator, we find that the Z-score is approximately 0.84.

Now, we can use the Z-score formula to find the corresponding score: X = Z * σ + μ. Plugging in the values, we get X = 0.84 * 30 + 185 = 208.2.

Therefore, a patient at the 80th percentile receives a score of approximately 208.2.

a. To find the probability of a patient scoring above 192 on the endurance test, we first calculate the Z-score. This allows us to standardize the score by measuring how many standard deviations it is from the mean. We then use a Z-table or calculator to find the probability corresponding to this Z-score, which is approximately 0.4090 or 40.90%.

b. To find the score at the 80th percentile, we first need to find the Z-score that corresponds to an area of 0.80 to the left.

Answer:

After reflection over the x-axis, we have the coordinates as follows;

A’ (5,-2)

B’ ( 1,-2)

C’ (3,-6)

Step-by-step explanation:

Here, we want to find the coordinates A’ B’ and C’ after a reflection over the x-axis

By reflecting over the x-axis, the y-coordinate is bound to change in sign

So if we have a Point (x,y) and we reflect over the x-axis, the image of the point after reflection would turn to (x,-y)

We simply go on to negate the value of the y-coordinate

Mathematically if we apply these to the given points, what we get are the following;

A’ (5,-2)

B’ ( 1,-2)

C’ (3,-6)

If the ratio of A to B is \(3 : 4\), and the ratio of B to C is \(2 : 3\), then the value of A when C is \(5\) is \(2.5\).

In the given question,

The ratio of A to B is \(3 : 4\).

The ratio of B to C is \(2:3\).

We have to find the value of A.

It is given that the value of C is \(5\).

The given ratios are,

A : B \(=3 : 4\)

B : C \(=2:3\)

As we can see that the ratio of B is not same in both ratio so we first equal the ratio of B.

We can equal the ratio of B by multiplying \(2\) on both side in the ratio of

B : C.

B : C \(=2\times2:3\times2\)

After multiplying we get

B : C \(=4:6\)

As given in the question that C \(=5\).

They given in the ratio which means there have any number in the multiple of ratio. That which we can get real value from the ratio.

So we used \(x\) as a multiple of ratio.

And the ratio of C is \(6x\).

So we get that

\(6x=5\)

Hence the value of \(x=\frac{5}{6}\).

Now finding the value of A.

The ratio of A is \(3x\).

And the value of \(x=\frac{5}{6}\).

Now putting the value

A \(=3\times\frac{5}{6}\)

A \(=\frac{5}{2}\)

A =\(2.5\).

The value of A is \(2.5\).

Hence, if the ratio of A to B is \(3 : 4\), and the ratio of B to C is \(2 : 3\), then the value of A when C is \(5\) is \(2.5\).

The sample proportion of 70% (or 0.70) would be considered unusual because the statistic falls more than three standard errors from the mean.

To determine whether a sample proportion is considered unusual, we can compare it to the expected population proportion. In this case, the assumed proportion of women in the population is 51% (or 0.51).

To assess the unusualness of the sample proportion of 70% (or 0.70), we can use the concept of standard errors. The standard error measures the variability or uncertainty of a sample proportion. In general, when a sample proportion is within three standard errors of the population proportion, it is considered not unusual.

However, if the sample proportion falls more than three standard errors away from the population proportion, it suggests a significant difference between the sample and population. This could indicate that the observed proportion is unlikely to occur by random chance alone.
