The probability is 121​ or 8.33 %.

To identify the P(x=4), we must create a table for better understanding;

+ 1 2 3 4 5 6

1 (1,1) = 2 (2,1) = 3 (3,1) = 4 (4,1) = 5 (5,1) = 6 (6,1) = 7

2 (1,2) = 3 (2,2) = 4 (3,2) = 5 (4,2) = 6 (5,2) = 7 (6,2) = 8

3 (1,3) = 4 (2,3) = 5 (3,3) = 6 (4,3) = 7 (5,3) = 8 (6,3) = 9

4 (1,4) = 5 (2,4) = 6 (3,4) = 7 (4,4) = 8 (5,4) = 9 (6,4) = 10

5 (1,5) = 6 (2,5) = 7 (3,5) = 8 (4,5) = 9 (5,5) = 10 (6,5) = 11

6 (1,6) = 7 (2,6) = 8 (3,6) = 9 (4,6) = 10 (5,6) = 11 (6,6)  =12

Based on the table, there are 3 numbers of ways that P(x=4). That is (1,3) , (2,2), and (3,1) out of 36 outcomes (6x6 = 36). Therefore, the probability of an event is:  363​, Reduce to the lowest term: is 121​ or 8.33 %.

Probability is a branch of mathematics that quantifies the likelihood of an event occurring or the likelihood of a statement being true. The probability of an event is a number between 0 and 1, with approximately 0 indicating the improbability of the event and 1 indicating certainty.

The missing Value, x, that when multiplied by 5/3^4 gives the result of 5^4 is 13125.

The missing value that, when multiplied by 5/3^4, gives the result of 5^4, we can set up the equation:

(5/3^4) * x = 5^4

To solve for x, we can simplify both sides of the equation. First, let's simplify the right side:

5^4 = 5 * 5 * 5 * 5 = 625

Now, let's simplify the left side:

5/3^4 = 5/(3 * 3 * 3 * 3) = 5/81

Now we have:

(5/81) * x = 625

To solve for x, we can multiply both sides of the equation by the reciprocal of 5/81, which is 81/5:

(81/5) * (5/81) * x = (81/5) * 625

On the left side, the fraction (81/5) * (5/81) simplifies to 1, leaving us with:

1 * x = (81/5) * 625

Simplifying the right side:

(81/5) * 625 = 13125

Therefore, the missing value, x, that when multiplied by 5/3^4 gives the result of 5^4 is 13125.

Step-by-step explanation:

Let the missing number be x

According to the question,

4x = 50-6

4x = 44

x = 44/4

x = 11

Step-by-step explanation:

The x intercept is the point where the line crosses the x axis. At this point y = 0. ... To find the x intercept set y = 0.

The mean, variance and the standard deviation for the distance travelled by 10 students is computed as-

Mean  = 3.12; standard deviation = 1.8232; variance = 3.324

Total students n = 10 .

Given the information, 1, 5, 2, 3, 5, 4, 8, 1, 2, 2, 5, 1.5, and 0.8

To determine the mean, we must first add up all the information provided and divide it by the number of students.

X = 1.1 + 5.2 + 3.6 + 5.0 + 4.8 + 1.8 + 2.2 + 5.2 + 1.5 + 0.8

X = 31.2

Mean  = X/n

Mean  = 31.2/10

Mean  = 3.12

Now the standard deviation is estimated as-

S = √∑x² - [(∑x)²/n] / (n-1)

Putting the values-

s = 1.8232

standard deviation = 1.8232

The variance is estimated by -

variance = S²

S² = 1.8232²

variance = 3.324

Thus, the mean, variance and the standard deviation for the distance travelled by 10 students is computed.

FALSE. The number of degrees of freedom in cross-tabulation data is calculated by subtracting 1 from the product of the number of rows and columns.

Therefore, in this case, the number of degrees of freedom would be (3-1) x (4-1) = 6.

Degrees of freedom refer to the number of independent pieces of information in a data set, which can be used to calculate statistical significance and test hypotheses.

The answer is Critical value.

Lets try to answer this :

A critical value is a value used to determine whether or not to reject a null hypothesis when testing a hypothesis. A critical value is also referred to as a cut-off point or rejection region. A critical value is a point on a scale that separates the rejection area from the acceptance area in a statistical hypothesis test.

A t-test is a statistical hypothesis test that involves comparing the mean of two populations. A t-table is used to look up critical values for a t-test. When the t-value is computed, it can be compared to the critical value to determine whether or not to reject the null hypothesis.

The maximum volume of the largest rectangular box that can be inscribed in the ellipsoid can be calculated by finding the x, y, and z coordinates in the first octant that satisfy the equation (x^2/4) + (y^2/64) + (z^2/49) = 1.

Since the box must have edges parallel to the axes, the coordinates will also be the lengths of the box's edges. From the equation, we get the x coordinate to be 2, the y coordinate to be 8, and the z coordinate to be 7.

The volume of the box is the product of its edges, so the maximum volume of the box is V = 8xyz = 8 * 2 * 8 * 7 = 896.

There are only one way to pick exactly 6 of the 7 winning numbers without regard to order.

There are "1 to 70 numbers, choose 7 " or 70C7 ways to pick 7 correctly.

AND

you must also pick 1 wrong number.  That wrong number has to be

different from any of the 7 correct numbers, and so there are

40-6 or 34 wrong numbers you could have picked.  That's 34 wrong

numbers, choose 1 or 34C1. Since AND means to multiply, the

numerator is 6C5 X 34C1=204

The denominator is the same 3838380 as in part (A)

So the desired probability is 204 / 38380 = 17 / 319865.

However that's just the probability of winning the $10000.

The words "probability of winning" could be taken as the

probability of winning either $1,000,000 OR $10,000. So

P(winning $1,000,000 OR winning $10,000) and since

"OR" means "ADD", we add the probability found in part A,

so the correct answer is 1 / 38380 + 204 / 38380 = 205 / 3838380
