The mean, which measures the central tendency of the data, is the average or computed central value of a set of numbers. The statistical metric known as central tendency identifies the complete collection of data or distribution by a single value. It offers a precise description of the entire set of facts. The ratio of the total number of observations to the sum of all observations is another way to define the mean in statistics.

Difference of mean :

x bar₁ - x bar₂ = 15.75 - 15.50 = 0.25

test statistics:

0.25/√0.011111+ 0.016409

0.25/16589

t = 1.50

The value of angle S is 53°

Exterior angle theorem states that the measure of an exterior angle of a triangle is equal to the sum of two remote interior angles.

With this theorem we can say that

7x+2 = 4x+13+19

collecting like terms

7x -4x = 13+19-2

3x = 30

divide both sides by 3

x = 30/3

x = 10

Since x = 10

angle S = 4x+13

angle S = 4(10) +13

= 40+13

= 53°

Therefore the measure of angle S is 53°

Answer:

40%

Step-by-step explanation:

10 minutes late would mean 18 minutes late on the graph. The graph goes from 10-30 which creates a difference of 20. 8 divided by 20 equals 40 percent.

40 percent of the time does Oliver arrives within 10 minutes of John's arrival time.

Given that,

Oliver is typically 10–30 minutes late for his shift at work.

The distribution for the minutes he is late forms a consistent pattern, which can be graphed as the given uniform density curve.

John and Oliver are working a shift that starts at the same time. John always arrives 8 minutes late.

We have to determine,

What percentage of the time does Oliver arrive within 10 minutes of John's arrival time?

According to the question,

Oliver is typically 10–30 minutes late for his shift at work.

John and Oliver are working a shift that starts at the same time.

John always arrives 8 minutes late.

From the complete information, the probability distribution will be:

\(= \dfrac{1}{b-a}\\\\= \dfrac{1}{30-10}\\\\= \dfrac{1}{20}\)

Here, John always arrives 8 minutes late.

Therefore,

The percentage of the time that Oliver arrives within 10 minutes of John's arrival time is,

\(\rm = 8 \times \dfrac{1}{20}\\\\= \dfrac{2}{5}\\\\= 0.4 \times 100 \\\\= 40 \ Percent\)

Hence, 40 percent of the time does Oliver arrives within 10 minutes of John's arrival time.

The guy wire must be about 55 feet long and the slope of the guy wire, expressed as a fraction is 25/11.

We can use the Pythagorean Theorem to find the length of the guy wire. Let's call the length of the guy wire "g".

g^2 = 50^2 + 22^2

g^2 = 2500 + 484

g^2 = 2984

g ≈ 54.65

So the guy wire must be about 55 feet long.

The slope of the guy wire is the ratio of the vertical distance it covers to the horizontal distance it covers. In this case, the vertical distance is 50 feet (the height of the pole) and the horizontal distance is 22 feet. So the slope is

50/22 = 25/11

Therefore, the slope of the guy wire is 25/11.

The appropriate soil media depth for the green roof can be determined, taking into account the WQv requirement and the structural limitations of the rooftop.

a) The WQv represents the volume of water that needs to be managed to meet water quality regulations. To calculate the WQv, the 90% rainfall number (P = 1.2 in) is used. The WQv can be determined by multiplying the rainfall number by the surface area of the rooftop reserved for the green roof (30 ft x 100 ft x 0.4, considering 60% reserved for maintenance access and equipment).

b) The minimum soil media depth needed to meet the WQv can be calculated by dividing the WQv by the product of the soil media porosity (20%) and the drainage layer depth (2 in).

c) Finally, the soil media depth for the green roof design needs to be determined. It should not exceed the maximum allowed soil depth of 1 foot.

Answer:

(a) Fermat's little theorem states that for any prime p , we have

a^p-1 = 1 (mod p).

for any integer ,a. Then

999999 = 1000000 - 1 = 10^6 - 1 = 1 - 1 = 0 (mod 7)

so 7 does indeed divide 999,999.

(b) Generalizing, we have

10^12n - 1 = 999...999 (12n nines) = (10^n)^12 - 1 = 0 (mod 13)

for positive integer, n. Now, since 1 = 1001 - 1000 and -1 = (mod 1001) , it follows that 10^3 is its own inverse modulo 1001, i.e.

10^3 x = 1 (mod 1001) -----> x = 10^3

This means

10^12n = (10^3 x 10^3)^2n = 1^2n = 1 (mod 1001) ----> 10^12n - 1 = 0 (mod 1001)

The value of ∠WXY = 20.

What is Exterior angle theorem?

The exterior angle theorem describes the connection between the two remote angles in a triangle and the external angle created by an extended side outside the triangle.

Given: Measure of angle YWX = (3x + 17) °

Measure of angle WXY = (3x + 2) °

Measure of angle XYZ = (10x − 5) °

Therefore, m∠XYZ = m∠YWX + m∠WXY (exterior angle theorem)

⇒ (10x − 5) ° = (3x + 17) ° + (3x + 2) °

Solve for x,

⇒ 10x - 5 = 3x + 17 + 3x + 2

⇒ 10x - 6x = 17 + 7

⇒ 4x = 24

⇒ x = 6

∴ ∠WXY = (3x + 2) = 18 + 2 = 20

Hence, value of ∠WXY = 20.

( Brainlyst will help my rank, thanks! <3 )

(a) To calculate the probability of exactly half of the spins landing on black, we need to consider the number of ways we can choose exactly five out of the ten spins to land on black. The probability of a single spin landing on black is 18/38, and the probability of a single spin landing on red (since there are only two possibilities) is 20/38.

We can use the binomial probability formula to calculate the probability:

P(X = k) = C(n, k) * p^k * q^(n-k)

where:

P(X = k) is the probability of exactly k successes,

C(n, k) is the number of combinations of n items taken k at a time,

p is the probability of success on a single trial, and

q is the probability of failure on a single trial.

For exactly half of the spins (k = 5), the probability can be calculated as:

P(X = 5) = C(10, 5) * (18/38)^5 * (20/38)^5

Calculating this expression will give us the probability that exactly half of the spins land on black.

(b) To calculate the probability of at least eight spins landing on black, we need to consider the probabilities of eight, nine, or ten spins landing on black and add them up.

P(X ≥ 8) = P(X = 8) + P(X = 9) + P(X = 10)

Using the same binomial probability formula, we can calculate each of these probabilities:

P(X = 8) = C(10, 8) * (18/38)^8 * (20/38)^2

P(X = 9) = C(10, 9) * (18/38)^9 * (20/38)^1

P(X = 10) = C(10, 10) * (18/38)^10 * (20/38)^0

By calculating these expressions and summing them up, we can determine the probability of at least eight spins landing on black.

are 2 so we can multiply all term by 2

2(3x/2 - 15/2 - 3/2 = 9x/2)

3x - 15 - 3 = 9x ... simplify it

3x - 12 = 9x

If a null hypothesis is rejected at the 0.02 level of significance, it can also be rejected at the 0.08 level of significance.

The decision to reject or fail to reject a null hypothesis depends on the p-value obtained from the statistical test. If the p-value is less than or equal to the chosen level of significance, the null hypothesis is rejected. Therefore, if the null hypothesis is rejected at a more stringent significance level of 0.02, it implies that the p-value is even smaller than 0.02 and would also be smaller than 0.08. Consequently, the null hypothesis can be rejected at the 0.08 level of significance as well.

The significance level, often denoted as α (alpha), determines the threshold at which the null hypothesis is rejected. It represents the maximum probability of making a Type I error, which is rejecting the null hypothesis when it is true. For example, if we set the significance level at 0.05, it means we are willing to accept a 5% chance of making a Type I error.

When performing a statistical test, we calculate the p-value, which represents the probability of obtaining the observed data (or more extreme) under the assumption that the null hypothesis is true. If the p-value is smaller than or equal to the chosen significance level, we reject the null hypothesis in favor of the alternative hypothesis.

In this case, if the null hypothesis is rejected at the 0.02 level of significance, it means that the p-value obtained is less than or equal to 0.02. Since the p-value is even smaller than 0.08, it follows that the null hypothesis can also be rejected at the 0.08 level of significance. The reason is that if the evidence against the null hypothesis is strong enough to reject it at a more stringent level, it will also be strong enough to reject it at a less stringent level. Therefore, rejecting the null hypothesis at a lower level of significance implies rejection at a higher level as well.
