The person who ate more is Joe.

Fractions are type of numbers which are written in the form p/q, which implies that p parts in a whole of q.

Here p, called the numerator and q, called the denominator, are real numbers.

Total number of cookies = 12

Fraction that Joe ate = 2/3

Fraction that Peggy ate = 1/3

From the fractions itself, we can say that Joe ate more since the numerator is bigger for the fraction that Joe ate.

Number of cookies that Joe ate = 2/3 × 12 = 8

Number of cookies that Peggy ate = 1/3 × 12 = 4

Hence the number of cookies is more eaten by Joe.

Answer:

I want to say that it is E

Step-by-step explanation:

Well in terms of probability there is a 50% chance the coin will land heads and a 50% chance the coin will land tails. Since probability isn't definite you can never really get a precise number of each side. the most you could do is predict/guess

The most likely outcome is: E. They are all equally likely.

Each individual toss of a fair coin has an equal probability of being a heads or tails, regardless of what the previous tosses were. Therefore, all of the outcomes listed are equally likely. The order in which the heads and tails occur does not affect the probability of the overall outcome.

So, even though (i) has an equal number of heads and tails in an alternating pattern and (iii) has all heads, they are both equally likely to occur. The same goes for (ii) and (iv), which have an equal number of heads and tails but in a random order.

Therefore, The most likely outcome is: E. They are all equally likely.

When extending beyond two dimensions, the analytical approach is generally easier to use than Euclidean geometry. The reason for this is that Euclidean geometry relies heavily on visualizing geometric shapes and their properties in three dimensions or higher, which can be difficult for most people.

In contrast, the analytical approach uses algebraic equations to describe geometric shapes and their properties, which can be more straightforward and intuitive for many individuals. The analytical approach also allows for the use of software tools to manipulate and visualize shapes in higher dimensions, which can be particularly useful for complex calculations and designs.

the mean absolute deviation of the set {16, 10, 22, 18, 4, 18, 14, 24, 16, 22} is 4.68.

To find the mean absolute deviation of a set of numbers, we first need to calculate the mean of the set.

The mean of the set {16, 10, 22, 18, 4, 18, 14, 24, 16, 22} is:

Mean = (16 + 10 + 22 + 18 + 4 + 18 + 14 + 24 + 16 + 22) / 10 = 16.4

Next, we need to calculate the absolute deviation of each number from the mean. The absolute deviation is the absolute value of the difference between the number and the mean.

The absolute deviations for each number in the set are:

|16 - 16.4| = 0.4

|10 - 16.4| = 6.4

|22 - 16.4| = 5.6

|18 - 16.4| = 1.6

|4 - 16.4| = 12.4

|18 - 16.4| = 1.6

|14 - 16.4| = 2.4

|24 - 16.4| = 7.6

|16 - 16.4| = 0.4

|22 - 16.4| = 5.6

Now, we need to find the mean of the absolute deviations.

Mean absolute deviation = (0.4 + 6.4 + 5.6 + 1.6 + 12.4 + 1.6 + 2.4 + 7.6 + 0.4 + 5.6) / 10

Mean absolute deviation = 4.68

Therefore, the mean absolute deviation of the set {16, 10, 22, 18, 4, 18, 14, 24, 16, 22} is 4.68.

We can compare the observed difference in medians between the V and NV groups to the difference in medians generated from the simulation in order to estimate a p-value for a test for the difference in medians.

We can count the number of simulation trials where the median difference is larger than or equal to the observed median difference in order to determine the p-value (V-NV). Assume that the median difference that was recorded is 5 (V-NV = 5).

Just a small number of trials, as shown by the dotplot, have median differences higher than or equal to 5. These trials can be counted manually or with software like R or Python. Say we discover 4 trials where the median difference is higher than or equal to 5.

The p-value is then determined as the percentage of simulation trials in which the median difference is larger than or equal to the observed median difference. The p-value in this instance is 4/100 = 0.04. As a result, since the p-value is lower than the significance level, we may say that the observed difference in medians is statistically significant at the 0.05 level.

Therefore , the solution of the given problem of angles comes out to be x has a value of 150°.

The two sides of a tilt in Euclidean geometry are actually spherical faces that divide at the centre and top of barrier. At the point where two rays meet, they might combine to form an angle. Angle is another outcome of two entities interacting. They mirror dihedral forms the most. A two-dimensional curve can be created by arranging two line beams in various configurations at their ends.

Here,

Since AE and BD are parallel, we can calculate the value of angle ABD using the alternate internal angles theorem:

=> BCD x ABD = 180

=>ABD = 150°, ABD + 30° Equals 180°.

Now, we can use the knowledge that a triangle's angles sum to 180 degrees to determine what angle AED is worth:

180° from ABD + AED + EDC is 150° from

=>AED + 180° is 180°.

=>AED = -150°

=>AED Plus BAE = 180

=> BAE + 30° = 180°

=> BAE = 150°

In order to determine the value of angle AEB, we can use the knowledge that the angles in a triangular sum to 180°:

=>AED 180° BAE AEB

=> AEB + 150° + 30° = 180°

=>AEB = 0°

.Points A, E, and B are collinear because angle AEB is 0°, and angle x equals angle ECD:

The mean weight of 32 students is 98.3 lb. The total weight of 32 students would be 3145.6 lb.

To find the total weight of 32 students, we need to multiply the mean weight of each student by the number of students. In this case, the mean weight of each student is 98.3 lb.

So, to find the total weight, we can use the formula:

Total weight = Mean weight × Number of students

Total weight = 98.3 lb × 32

Total weight = 3145.6 lb

Therefore, the total weight of 32 students would be 3145.6 lb.

It's important to note that the mean weight is the average weight of the 32 students. It is calculated by adding up the weight of each student and then dividing by the total number of students. So, if the weights of the students are evenly distributed, then the mean weight is a good estimate of the total weight. However, if the weights are not evenly distributed, then the total weight may be slightly different.

Rhombuses, parallelograms, squares, but also rectangles are the four distinct shapes.

Here,

We must demonstrate that OM = MR in order to establish that O is CR's middle.

=>  CO / OU Equals RC / UE

This solution can be rearranged to account for RC:

=>  RC Equals UE * (CO / OU)

But we also understand that OU = CO (since they are diagonals of the same parallelogram). Therefore:

=>  RC = UE

This indicates that point M, the CR's centre, is equally spaced from C and U. Or put another way, OM Equals MU.

To demonstrate that O is also the midpoint of UE, we can use a similar argument.

Triangles CRU and EUC are comparable to one another (by AA resemblance), so we have:
