The entire trip to the mall took 5 hours, and it was 24 miles away. Cameron biked for 2 hours and walked for 3 hours.

Cameron started biking to the mall at a speed of 9 mph. After some time, the bike got a flat so Cameron walked the rest of the way, traveling at a speed of 2 mph. The distance that Cameron biked to the mall was x, and the distance he walked to the mall was 24 - x.

Cameron traveled at two different speeds, 9 mph and 2 mph, and traveled a total of 24 miles. So the time he spent biking plus the time he spent walking was 5 hours, and we can create an equation:

Time biking + time walking = 5 hours x/9 + (24 - x)/2 = 5 hours

Multiply everything by 18 to remove the denominators:
2x + 9(24 - x) = 90
2x + 216 - 9x = 90-7x = -126x = 18
Time biking = x/9 = 18/9 = 2 hours
Time walking = (24 - x)/2 = (24 - 18)/2 = 3 hours

Therefore, Cameron biked for 2 hours and walked for 3 hours.

The largest factor of the sum of y and z is 24.

The replacement approach has the advantage of providing the precise values for the variables (x and y), which correspond to the site of intersection.

When using the "by substitution" method, you must first solve one of the equations provided (you must choose which one) for one of the variables (you must choose which one), after which you must plug this value back into the other equation provided (you must "substitute" for the chosen variable and solve for the other value). The first equation is then used to back-solve for the first variable. The many procedures required in using the replacement approach to solve problems have been described in full above. Use those to discover the solution to a given system of linear equations.

We are given with three equations having three unknowns:

x = z/4

x + y + z = 26

y = 2z

Using the method of substitution, we can now solve for each of the three unknowns.

Since the first equation, x = z/4, is an equation for x in terms of z, and the third equation, y = 2z, is an equation for y in terms of z, we can replace x and y in the second equation by their equivalent expressions as follows:

x + y + z = (z/4) + (2z) + z = 26

We are left with an equation with just one unknown z. We can now solve for z:

(z/4) + (2z) + z = 26

z/4 + 8z/4 + 4z/4 = 13z/4 = 26

z/4 = 2

z = 8

Now that we know z, we can easily solve for y, then compute y + z (note: we can also solve for x, but since we are not interested in the value of x there is no need to do so):

y = 2z = 2(8) = 16

y + z = 16 + 8 = 24

Since the largest factor of any number is the number itself, the largest factor of the sum of y and z is 24.

Answer:

Equation: 35.60 = 2.60 + 3x

It was 11 miles

Step-by-step explanation:

35.60 = 2.60 + 3x

3x = 33

x = 11

The linear function for the fare is:

\(F(x) = 2.6 + 3x\)

Solving the equation, it is found that the taxi ride was of 11 miles.

A linear function for a cost considering a distance of x miles has the following format:

\(F(x) = F(0) + ax\)

In which

In this problem:

The function is:

\(F(x) = 2.6 + 3x\)

Fare of $35.60, thus \(F(x) = 35.60\) and we solve for x to find the number of miles.

\(35.6 = 2.6 + 3x\)

\(3x = 33\)

\(x = \frac{33}{3}\)

\(x = 11\)

The points of intersection are (-0.4, -0.2) and (2.8, 16.8). The smallest x-value is -0.4 and the largest x-value is 2.8.

To graph the curves y = x^5 and x = y(y - 1)^2, first plot the points on the graph for y = x^5. This can be done by substituting in values for x and then finding the corresponding values for y. For example, when x = -3, y = -3^5 = -243. When x = 0, y = 0^5 = 0. When x = 3, y = 3^5 = 243. After plotting the points, draw a smooth curve connecting them. Next, plot the points on the graph for x = y(y - 1)^2. This can be done by substituting in values for y and then finding the corresponding values for x. For example, when y = -2, x = -2(-2 - 1)^2 = -2(-3)^2 = 18. When y = 0, x = 0(0 - 1)^2 = 0(-1)^2 = 0. When y = 4, x = 4(4 - 1)^2 = 4(3)^2 = 36. After plotting the points, draw a smooth curve connecting them. The curves intersect at two points. The points of intersection are (-0.4, -0.2) and (2.8, 16.8).

In a lower one-tail hypothesis test situation, the p-value is determined to be 0.1. If the sample size for this test is 31, the t statistic has a value of -1.31. Option B is the correct answer.

The one-tail hypothesis test is a statistical test used to assess whether a set of data differs significantly in one direction. A one-tailed test has a single critical region, and the critical value is dependent on the alternative hypothesis. A one-tail test is the correct choice when the researcher has prior knowledge about the direction of the effect and wishes to test that direction only. Therefore, in a lower one-tail hypothesis test situation, the rejection region would be on the left side of the distribution curve.

In this case, the critical value of t-statistic for a one-tailed test at a 10% level of significance with 30 degrees of freedom is -1.31. With a sample size of 31 and a t-statistic value of -1, we can conclude that the test statistic falls within the critical region and, therefore, the null hypothesis can be rejected. Therefore, the answer is -1.31.

A stone arch can be twice as wide as a stone lintel because an arch distributes the weight of the structure vertically down its curve to the columns (piers) on either side while a lintel distributes the weight horizontally along the length of the stone.

A stone arch can be twice as wide as a stone lintel because an arch distributes the weight of the structure vertically down its curve to the columns (piers) on either side while a lintel distributes the weight horizontally along the length of the stone.

It requires only a small fraction of the arch's width to support itself while a lintel requires the full width of the structure that it spans. Thus, a stone arch can span a larger gap than a stone lintel and be twice as wide while using the same material.

For example, the Roman Colosseum uses an arch to span the entrances and exits while the walls supporting the upper levels use a series of stone lintels to support the structure.

Moreover, the arc prevents the need for a central support structure, which would be in the way of any events taking place in the structure. The technology of arches made them fundamental to ancient Roman architecture. For example, the arches were used to construct aqueducts, which provided a steady supply of water to the city of Rome.

Vertical  deviations

Step-by-step explanation:

Multiplying ampere (amp) by ohm gives units of volt (V).

Therefore, the answer will be in volts (V). This is because ohm is the unit of electrical resistance, ampere is the unit of electrical current, and volt is the unit of electrical potential difference, which is calculated as the product of current and resistance according to Ohm's law: V = I × R.

Ohm is the unit of electrical resistance, which measures how much a material opposes the flow of electric current. One ohm (1 Ω) of resistance is defined as the amount of resistance that allows one ampere (1 A) of current to flow when a potential difference of one volt (1 V) is applied across it.

Ampere is the unit of electrical current, which measures the rate at which electric charge flows through a material. One ampere (1 A) of current is defined as the flow of one coulomb of electric charge per second.

Volt is the unit of electrical potential difference, which measures the amount of energy required to move a unit of electric charge from one point to another.

Answer:

  72 feet

Step-by-step explanation:

Triangle JKM is similar to triangle PQM, so we have ...

  JK/KM = PQ/QM

  JK/(60 ft) = (6 ft)/(5 ft)

  JK = (60 ft)(6/5)

  JK = 72 ft

The height of the cliff is 72 feet.

the size of the union of the three sets is: |A ∪ B ∪ C| = |A| + |B| + |C| - |A ∩ B| - |A ∩ C| - |B ∩ C| + |A ∩ B ∩ C| = 3  × 24 million - 3 × 1.4 million + 1.2 million ≈ 69 million

A combination is a way of selecting a subset of objects from a larger set without regard to their order. The formula for the number of combinations of n objects taken r at a time is:
C(n, r) = n! / (r! ×  (n - r)!)
where n! means the factorial of n, which is the product of all positive integers up to n. For example, 5! = 5 ×  4 ×  3 ×  2 ×  1 = 120.
To apply this formula to our problem, we first need to count the total number of coins in the pile. Since there are at least 16 of each type, the minimum total is:
16 + 16 + 16 + 16 = 64
But there could be more coins of each type, so the total could be larger than 64. However, we don't need to know the exact number, only that it is large enough to allow us to choose 16 coins from it.
Using the formula for combinations, we can calculate the number of different collections of 16 coins that can be chosen from the pile:
C(64, 16) = 64! / (16! × (64 - 16)!) ≈ 1.1 billion
That's a very large number! It means there are over a billion ways to choose 16 coins from a pile that contains at least 16 of each type.
To answer the second part of the question, we need to count the number of collections that contain at least 3 coins of each type. One way to do this is to use the inclusion-exclusion principle, which says that the number of elements in the union of two or more sets is equal to the sum of their individual sizes minus the sizes of their intersections, plus the sizes of the intersections of all possible pairs, minus the size of the intersection of all three sets, and so on.
In this case, we can consider three sets:
- A: collections with at least 3 pennies
- B: collections with at least 3 nickels
- C: collections with at least 3 dimes
- D: collections with at least 3 quarters
The size of each set can be calculated using combinations:
|A| = C(48, 13) ≈ 24 million
|B| = C(48, 13) ≈ 24 million
|C| = C(48, 13) ≈ 24 million
|D| = C(48, 13) ≈ 24 million
Note that we have to choose 3 coins of each type first, leaving 4 coins to be chosen from the remaining 48 coins.
The size of the intersection of any two sets can be calculated similarly:
|A ∩ B| = C(43, 10) ≈ 1.4 million
|A ∩ C| = C(43, 10) ≈ 1.4 million
|A ∩ D| = C(43, 10) ≈ 1.4 million
|B ∩ C| = C(43, 10) ≈ 1.4 million
|B ∩ D| = C(43, 10) ≈ 1.4 million
|C ∩ D| = C(43, 10) ≈ 1.4 million
Note that we have to choose 3 coins of each type first, leaving 1 coin to be chosen from the remaining 43 coins.
The size of the intersection of all three sets can also be calculated:
|A ∩ B ∩ C| = C(38, 7) ≈ 1.2 million
Note that we have to choose 3 coins of each type first, leaving 1 coin to be chosen from the remaining 38 coins.

The life length in hours is exceeded by 95/5% of the light bulbs is 1329 hours.

To find the life length in hours that is exceeded by 95% of the light bulbs, we need to determine the corresponding z-score for the 95th percentile and use it to calculate the value.

Since the distribution is assumed to be normal, we can use the standard normal distribution (z-distribution) to find the z-score. The z-score represents the number of standard deviations an observation is above or below the mean.

To find the z-score corresponding to the 95th percentile, we look for the z-value that corresponds to a cumulative probability of 0.95. This value can be obtained from standard normal distribution tables or using a statistical software/tool.

For a cumulative probability of 0.95, the corresponding z-score is approximately 1.645.

Once we have the z-score, we can calculate the exceeded life length as follows:

Exceeded life length = Mean + (Z-score * Standard deviation)

Exceeded life length = 1000 + (1.645 * 200)

Exceeded life length ≈ 1000 + 329

Exceeded life length ≈ 1329 hours

Therefore, approximately 95% of the light bulbs will have a life length that exceeds 1329 hours.

The size of the largest 10%( 10th percentile) of bladder volumes among men ≈ 416.8 ml.

To find the size of the largest 10% of bladder volumes among men, we need to calculate the corresponding z-score and then use it to find the corresponding value from the standard normal distribution.

Mean bladder volume for men is 550 ml and the standard deviation is 100 ml, we can calculate the z-score using the formula:

z = (x - μ) / σ

where x is the desired value, μ is the mean, and σ is the standard deviation.

To find the z-score for the 10th percentile (largest 10%), we can use the inverse standard normal distribution function (also known as the quantile function or the percent-point function).

This function gives us the z-score corresponding to a given percentile.

Using a statistical software or calculator, we can find the z-score corresponding to the 10th percentile (0.10).

Let's assume the z-score is denoted as z10.

We can calculate the corresponding value in milliliters (x10) using the formula:

x = μ + z * σ

Substituting the values for men:

μ = 550 ml

σ = 100 ml

percentile = 0.10

Using the software or calculator, we find that the z-score corresponding to the 10th percentile (largest 10%) is approximately -1.282.

Now, we can calculate the size of the largest 10% of bladder volumes among men (x10):

x10 = μ + z10 * σ

x10 = 550 + (-1.282) * 100

x10 ≈ 416.8 ml
