35/8

4 3/8 or 4.375

350 divided by 80 is equal to 4 with a remainder of 30, or in decimal form, it is approximately 4.375.

We have,

To divide 350 by 80, we can perform the division operation as follows:

- First, we check how many times 80 can be divided into 350. We start with the largest multiple of 80 which is less than or equal to 350, which is 4.

80 x 4 = 320

- We subtract 320 from 350 to find the remainder:

350 - 320 = 30

- Since the remainder is not zero,

We can continue dividing. We bring down the next digit of 350, which is 0.

- Now, we have 300 as the new dividend.

We ask ourselves how many times 80 can be divided into 300.

80 x 3 = 240

- Subtracting 240 from 300 gives us the new remainder:

300 - 240 = 60

- Again, the remainder is not zero, so we continue.

- We bring down the last digit of 350, which is 0, and our new dividend becomes 600.

- We ask ourselves how many times 80 can be divided into 600.

80 x 7 = 560

- Subtracting 560 from 600 gives us the new remainder:

600 - 560 = 40

- The remainder is still not zero, so we continue.

- Finally, we bring down the last digit of 350, which is 0.

Our new dividend is 400.

We ask ourselves how many times 80 can be divided into 400.

80 x 5 = 400

- Subtracting 400 from 400 gives us zero as the remainder.

Since the remainder is now zero, we can stop dividing.

Therefore,

350 divided by 80 is equal to 4 with a remainder of 30, or in decimal form, it is approximately 4.375.

In summary, 350 divided by 80 equals 4 with a remainder of 30, or 4.375.

Chebyshev's theorem states that if k is a positive number, then, in any data at least [tex](1 - 1/k^2)[/tex] of the data will fall in K standard deviations from the mean data.

For normal distributions, 68% of the values will fall within one standard deviation of the mean.

For non-normal deviations, 75% of values will fall within 2 standard deviations of the mean.

Here we need to find the Upper limit and lower limit of the data.

$3.75 - $0.09 = $3.66

$3.75 + $0.09 = $3.84

The price range will be between $3.66 and $3.84.

To calculate the minimum percentage of stores using Chebyshev's theorem

minimum percentage = [tex]1 - 1/k^2[/tex]

To prove that the right triangles are congruent, we need to show that they have three pairs of congruent parts (sides or angles).

Let's say that the given congruent parts are the hypotenuses and one leg of each triangle. To prove congruence, we can add one more pair of congruent parts, such as the other leg.

By the Side-Angle-Side (SAS) congruence theorem, if two triangles have two pairs of congruent sides and the included angle is also congruent, then the triangles are congruent. In this case, we have two pairs of congruent sides (the hypotenuses and one leg) and the included angle (the right angle) is congruent by definition.

Therefore, we can conclude that the two right triangles are congruent by SAS.

The measure of angle x is: x = (3/5)(180 - z) = (3/5)(180 - 90) = 36 degrees

And the measure of angle y is:y = (2/5)(180 - z) = (2/5)(180 - 90) = 24 degrees

Since lines lll, mmm, and nnn are parallel to each other and ppp is a transversal, we can use the angle properties of parallel lines to find the relationship between angle x and angle y.

From the given information, we have:  2x = 3y

Simplifying this equation, we get:  x = (3/2)y

Now, we can use this relationship to find the measures of angles x and y in terms of a common variable. Let's use z as the common variable.

x + y + z = 180 (angles on a straight line)

Substituting x = (3/2)y, we get:  (3/2)y + y + z = 180

Simplifying this equation, we get: (5/2)y + z = 180

Now, we can express y in terms of z:

(5/2)y = 180 - z

y = (2/5)(180 - z)

Similarly, we can express x in terms of z:

x = (3/2)y = (3/2)(2/5)(180 - z) = (3/5)(180 - z)

Now, we can use the relationship between angle x and angle y to find the measure of angle x in terms of z: 2x = 3y

2[(3/5)(180 - z)] = 3[(2/5)(180 - z)]

The way you wrote it with the " * " symbol, it means the multiplication of 6x and 2. This is what I did in the line below.

6x × 2 + 17 = 6 × 8 × 2 + 17 = 48 × 2 + 17 = 113

If by " * " you actually meant an exponent, such as 6x², then here is the calculation using 2 as an exponent. For exponent, we normally use ^, such as 6x^2 to mean 6x².

6x² + 17 = 6 × 8² + 17 = 6 × 64 + 17 = 384 + 17 = 401

To compute the number of 12 letter combinations of the 26 letters in the alphabet, we can use the formula for combinations, which is:

nCr = n! / r!(n-r)!

where n is the total number of items (26 letters in this case), r is the number of items to choose (12 letters in this case), and ! means factorial (the product of all positive integers up to that number).

Using this formula, we can plug in the numbers:

26C12 = 26! / 12!(26-12)!
= (26 x 25 x 24 x 23 x 22 x 21 x 20 x 19 x 18 x 17 x 16 x 15) / (12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1)

There is not enough evidence to conclude that Devon's true proportion of good serves is greater than 72%.

The correct conclusion for Devon to reach is: Because the P-value of 0.06 > a (where a = 0.05), Devon should fail to reject H0. There is no convincing evidence that the proportion of services that are good is more than 72%.

The null hypothesis, H0, states that the true proportion of good serves for Devon is equal to 72%. The alternative hypothesis, Ha, states that the true proportion of good serves for Devon is greater than 72%.

The P-value is the probability of obtaining a test statistic as extreme or more extreme than the observed data, assuming that the null hypothesis is true. In this case, the P-value is 0.06, which means that if the true proportion of good serves for Devon is actually 72%, there is a 6% chance of observing a sample of 50 serves with 42 or more good serves.

The median number of goals scored is 1, and the mean number of goals scored is 2. The median is less than the mean, indicating a right-skewed distribution.

To find the median, we need to first put the numbers in order

0, 0, 1, 1, 1, 3, 3, 4, 5

There are an odd number of values, so the median is the middle value, which is 1.

To find the mean, we add up all the values and divide by the number of values

(0 + 0 + 1 + 1 + 1 + 3 + 3 + 4 + 5) / 9 = 2

So the mean number of goals scored is 2.

Since the median (1) is less than the mean (2), we can say that the distribution is skewed to the right. This is because the high value of 5 pulls the mean up, while the median is not affected as much by outliers.

To find the equation of a line that is parallel to the graph of 2x - 3y = 7, we need to determine the slope of the given line. We can rewrite the equation in slope-intercept form:

2x - 3y = 7

-3y = -2x + 7

y = (2/3)x - 7/3

This implies that the slope of this line is m = 2/3.

Thus, the equation of the line we are to find will take the following form:

y = (2/3)x + b

where b is the y-intercept of the line.

To find the y-intercept (b), substitute (x, y) = (-3, -3) and m = 2/3 into y = mx + b:

To calculate the standard deviation of X, we need to first calculate the probability of drawing a red marble on the first draw, which is 11/29. The probability of not drawing a red marble on the first draw is 18/29. The probability of drawing a red marble on the second draw, given that we did not draw a red marble on the first draw, is 11/29. Using the formula for the geometric distribution, which models the number of trials until the first success, we can calculate the expected value of X, which is 1/p, where p is the probability of success (11/29 in this case).

Therefore, the expected value of X is 29/11. To calculate the standard deviation of X, we use the formula sqrt(q/p^2), where q is the probability of failure (18/29) and p is the probability of success (11/29). Plugging in these values, we get the standard deviation of X to be approximately 0.4852.  Therefore, the correct answer is option A, 0.4852.
