Answer:

40 students were in each bus on the trip.

Step-by-step explanation:

Since 20 students rode in cars, subtract 20 from 340. This results in 320.

There are 8 school busses, so divide 320 student into 8 busses.

This results us in 40 students in each bus.

Answer:

40 students in each bus.

Step-by-step explanation:

340= Students total on the trip

20= The students who rode in cars

340-20=320

8= The number of students that were in each bus

320/2=40

So, 40 students were in each bus.

Answer:

Step-by-step explanation:

2x+15+x+10+3x+5=180 degree(sum of interior angles of a triangle)

6x+30=180

6x=180-30

x=150/6

x=25

therefore the value of x is 25 degree.

Given that S be a submodule of m and x belongs to S. We are to prove that +Rx SS Rx1 + Rx+.

As S is a submodule of M, thus by definition, it is closed under addition and subtraction, and it is closed under scalar multiplication.

Also, we have x belongs to S. Therefore, for any r in R, we have rx belongs to S.

Thus we have S is closed under scalar multiplication by R, and so it is an R-submodule of M.

Now, let y belongs to Rx1 + Rx+. Then, by definition, we can write y as:

y = rx1 + rx+

where r1, r2 belongs to R.

As x belongs to S, thus S is closed under addition, and so rx belongs to S.

Therefore, we have y belongs to S, and so Rx1 + Rx+ is a subset of S.

Now let z belongs to S. As Rx is a subset of S, thus r(x) belongs to S for every r in R.

Hence, we have z = r1(x) + r2(x) + s where r1, r2 belongs to R and s belongs to S.

Also, as Rx is a submodule of S, thus r1(x) and r2(x) belong to Rx.

Therefore, we can write z as z = r1(x) + r2(x) + s where r1(x) and r2(x) belong to Rx and s belongs to S.

As Rx1 + Rx+ is closed under addition, thus we have r1(x) + r2(x) belongs to Rx1 + Rx+.

Hence, we can write z as z = (r1(x) + r2(x)) + s where (r1(x) + r2(x)) belongs to Rx1 + Rx+ and s belongs to S.

Thus we have S is a subset of Rx1 + Rx+.

Therefore, we have +Rx SS Rx1 + Rx+.

Answer:

4km/1.5km

Step-by-step explanation:

hope that helps :)

Ratio of 400m to 1.5km​ is 400/1500 or 400:1500

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Here the given quantities are 400m and 1.5km

The quantities are with different unit

We convert them into same unit

We know that one kilometre=1000 metre

One kilometre equal to thousand metres.

Let us convert 1.5 km to metre by multiplying 1.5 with 1000

1.5×1000=1500

The ratio of 400m to 1.5km​ is 400/1500 or 400:1500

Hence  ratio of 400m to 1.5km​ is 400/1500 or 400:1500

The half-life of sodium-24 is around 15 hours. If just 1/8 of the sodium-24 is left, it has been eliminated in 60 hours.

The half-life is the amount of time needed for half of the initial population of radioactive atoms to decay. T1/2 = 0.693/λ is the equation that describes the connection between the half-life, T1, and the decay constant. The rate of radioactive atoms decaying at any given instant is precisely proportional to the quantity of atoms present at that time, as stated by the radioactive decay law.

dtd N ∝ N

dtd N = λ N

To construct a stem and leaf plot, you first need to separate each data point into a stem and a leaf. The stem represents the leading digit(s) of the data point, while the leaf represents the trailing digit(s).

Once you have organized the data in this way, you can create the plot. The stems are listed vertically, and the leaves are placed horizontally next to their corresponding stems. Make sure to arrange the leaves in ascending order.

Regarding how the stem and leaf plot suggests the sample mean and median will compare, we can look at the distribution of the data. If the leaves are evenly distributed across the stems, it suggests a symmetrical distribution. In this case, the sample mean and median will be similar.

However, if the leaves are concentrated in certain stems, it suggests an asymmetrical distribution. In this scenario, the sample mean and median may differ. The median tends to be less affected by extreme values, while the mean can be influenced by outliers.

Therefore, by examining the stem and leaf plot, you can get a sense of whether the sample mean and median will be similar or different based on the distribution of the data.

Between clock skew and clock jitter, skew is preferred because it is more predictable and can sometimes increase max frequency. This makes it easier to manage in electronic systems and can provide benefits in certain scenarios.

Jitter is preferred because it is predictable. Clock jitter refers to the variability of the clock signal and can be predicted and compensated for. On the other hand, clock skew refers to the difference in arrival time of the clock signal at different points in the circuit and can sometimes increase maximum frequency. However, skew is preferred because it is more predictable and can be compensated for, while jitter is preferred because it is unpredictable and can't be compensated for. Therefore, in general, jitter is considered more preferable than skew.

Place the compass on point B and complete the same steps that she did for point A

The process is that you draw arcs above and below the line from both ends, but it's crucial that the compass' radius is the same from both ends of the line.  Then you draw the line that connects the two intersection points to form your perpendicular bisector.

If A is a subset of B, it does not necessarily mean that A is a proper subset of B. The union of any set A and its complement is indeed the universal set.

1. False: If A is a subset of B, it does not necessarily mean that A is a proper subset of B. A proper subset is a subset that contains some, but not all, elements of the superset. In other words, if A is a proper subset of B, it means that there exists at least one element in B that is not in A. However, if A is simply a subset of B, it is possible for A and B to have the same elements, making them equal sets.

For example, let's consider two sets:

A = {1, 2}

B = {1, 2, 3}

In this case, A is a subset of B because every element in A (1 and 2) is also in B. However, A is not a proper subset of B since there are no elements in B that are not in A. Therefore, statement 1 is false.

2. True: The union of any set A and its complement is indeed the universal set. The complement of a set A, denoted as A', consists of all elements that are not in A but are in the universal set U. When we take the union of A and its complement, we are effectively combining all elements from A and all elements not in A.

Let's consider a set A and its complement A' within a universal set U. The union of A and A' is denoted as A ∪ A' and can be represented as U. This is because every element in the universal set U is either in A or not in A (in A').

For example, let's consider the following sets:

U = {1, 2, 3, 4, 5}

A = {1, 2}

The complement of A, A', would be {3, 4, 5}. The union of A and A' (A ∪ A') is {1, 2} ∪ {3, 4, 5}, which is equal to U: {1, 2, 3, 4, 5}. Thus, the union of any set A and its complement is indeed the universal set. Therefore, statement 2 is true.

This matches the placement of 10, 15, and 20 and hence the standard deviation will be the same in the two cases.

What is the standard deviation?

The standard deviation in statistics is a measure of the amount of variation or dispersion in a set of values. A low standard deviation indicates that the values are close to the set's mean, whereas a high standard deviation indicates that the values are spread out over a wider range.

Standard deviation determines how far numbers deviate from the mean. The Standard deviation of the two sets will be the same if the numbers from the respective means are placed in the same order.

This is what 10, 15, and 20 will be on a number line

The average number of miles he will ride each day to meet his goal is 6.6 miles

He wants to ride his bicycle 30.4 miles this week.

He has already ridden 4 miles.

He rides 4 more days.

Therefore, the average number of miles he would have to ride each day to meet his goal can be calculated as follows:

let

x = number of miles driven

Hence, the equation can be represented as follows;

4x + 4 = 30.4

Therefore,

4x + 4 = 30.4

4x + 4 - 4 = 30.4 - 4

4x = 26.4

x = 26.4 / 4

x = 6.6
