Step-by-step explanation:

t2 = a*r

t2 = 6

The probability of getting all three tosses to head is 1/8.

We have,

When a coin is tossed, there are two possible outcomes:

heads (H) or tails (T).

Since there are three tosses, the total number of possible outcomes.

2³ = 8.

The probability of getting heads on one toss is 1/2.

The probability of getting heads on all three tosses is the product of the probabilities of getting heads on each individual toss:

P(HHH) = P(H) x P(H) x P(H) = (1/2) x (1/2) x (1/2) = 1/8.

Therefore,

The probability of getting all three tosses to head is 1/8.

There are several possible reasons why per capita per day water consumption could be higher than the wastewater generated:

Non-domestic water use: Per capita water usage includes not only water used in households but also water used for commercial, industrial, and agricultural purposes. Wastewater, on the other hand, only includes water that has been used in households and is discharged into the sewer system. Therefore, if there is significant non-domestic water use in the area, per capita water usage could be higher than wastewater generated.

Inefficient water use: Even though per capita water usage is high, some of the water used may not end up in the wastewater stream. For example, water may be used for landscaping or irrigation, and much of it could evaporate or soak into the ground before it reaches the sewer system. This would result in higher water usage than wastewater generated.

Water loss: The water distribution system may experience leaks or other losses, resulting in some of the water being lost before it reaches households or other water users. This would result in higher water usage than wastewater generated.

Infiltration and inflow: In some cases, rainwater or groundwater can infiltrate into the sewer system or inflow into wastewater treatment plants, increasing the volume of wastewater generated. This could result in lower wastewater generated than per capita water usage.

Time lag: There may be a time lag between water usage and wastewater generated, especially in areas with septic systems. It is possible that some of the water used today may not be discharged into the sewer system for several days or even weeks, resulting in higher per capita water usage than wastewater generated on any given day.

The F-ratio is a measure used in statistical tests, specifically in ANOVA (Analysis of Variance) to test for differences between means of multiple groups.

a) On average, what value is expected for the F-ratio if the null hypothesis is true?

The answer is a. 1. If the null hypothesis is true, it means that there is no significant difference between the means of the groups being compared. Under this assumption, the F-ratio is expected to have a value close to 1, as the variance between the groups is not significantly different from the variance within the groups.

b) On average, what value is expected for the F-ratio if the null hypothesis is false?

The answer is d. Much greater than 1.00. If the null hypothesis is false, it means that there is a significant difference between the means of the groups being compared. Under this assumption, the F-ratio is expected to have a value much greater than 1, as the variance between the groups is significantly larger than the variance within the groups.

The null and alternative hypotheses for the question of whether there is strong evidence to conclude that the standard deviation of performance time exceeds the historical value of 0.75 seconds are as follows:Null hypothesis: σ ≤ 0.75Alternative hypothesis: σ > 0.75.

The test statistic used to test this hypothesis is given by:t = (s/√n) / (σ/√n) = s/σWhere s is the sample standard deviation, n is the sample size, and σ is the population standard deviation (which is hypothesized to be 0.75 in this case).In this particular scenario, there were 17 players and the sample standard deviation of performance was 0.09 seconds.Using the formula, we can calculate the test statistic:t = 0.09/0.75 = 0.12 Since we are testing the alternative hypothesis that the standard deviation exceeds the historical value of 0.75 seconds (i.e., we are interested in the right tail of the t-distribution), we need to find the critical value for a one-tailed t-test with 16 degrees of freedom and a significance level of 0.05.

Using a t-distribution table or a calculator, we find the critical value to be 1.746. Since our calculated test statistic of 0.12 is less than the critical value of 1.746, we fail to reject the null hypothesis.There is not strong evidence to conclude that the standard deviation of performance time exceeds the historical value of 0.75 seconds.

Based on what Mia recorded, we calculate that 152 people are expected to go to the Youth wing on Sunday.

We solve this problem using simple arithmetic methods. According to the data collected by mia,

The number of people who went to the "Youth wing" = 470

The number of people who went to "Social issues" = 413

The number of people who went to "Fiction and Literature" = 350

So, the total number of visitors that the library had on Saturday was,

470+413+350 = 1233

Hence, the proportion of people who went to the "Youth wing", "Social issues" and "Fiction and Literature" are (470/1233), (413/1233), (and 350/1233) respectively.

So, on Sunday the expected number of people who may go to the "Youth wing" should be,

(470/1233)×400

Bob and John working together would take 4 hours to do the job.

1. Let's assume that Bob takes x hours to complete the job alone.
2. John would take x + 1 hour to complete the job alone, since it takes him 1 hour longer than Bob.
3. Steven would take 2x hours to complete the job alone, since it takes him twice as long as Bob.
4. Together, Bob, John, and Steven take x - 6 hours to complete the job, since it takes them 6 hours less than Bob alone.
5. Combining the information, we have the equation x - 6 = (x + 1) / 2.
6. Solving for x, we find that x = 14.

A rectangle is a part of a quadrilateral, whose sides are parallel to each other and equal.

The given points are,

(0, 0), (0, 4), (8, 4) and (8,0).

To determine the section for the quadrilateral,

Find distance between points.

The distance between two points A(x₁, y₁) and B(x₂, y₂)

Distance

= √(x₂ - x₁)² + (y₂ - y₁)²

The distance between (0, 0) and (0, 4)

= √(0-0)² + (4-0)² = √(0)² + (4)² = √(4)² = 4

The distance between (0, 4) and (8, 4)

= √(8-0)² + (4-4)² = √(8)² + (0)² = √(8)² = 8

The distance between (8, 4) and (8, 0)

= √(8 - 8)² + (0 - (4))² = √(0)² + (4)² = √(4)² = 4

The distance between (8, 0) and (0, 0)

= √(0 - 8)² + (0- 0)² = √(-8)² + (0)² = √(8)² = 8

Answer:

y =47.5.

Step-by-step explanation:

First eliminate the fractions by multiplying through by the LCM of 7 and 3 which is 21:

21* 6[y-2]/7-21*12 = 21*2[y-7]/3

18(y - 2) - 252 = 14(y - 7)

18y -36 - 252 = 14y - 98

18y - 14y = -98 + 36 + 252

4y = 190

y = 190/4

y = 47.5.

The table has a greater rate of change.

The rates of change are equal.

In the given problem, we have a table showing the relationship between x and y values. By comparing the change in y with the change in x, we can determine the rate of change. Looking at the table, we observe that for every increase of 1 in x, there is a corresponding increase of 1 in y. Therefore, the rate of change for this table is 1.

The slopes are equal.

The equation has a greater slope.

In problem 2, we are given a linear equation in the form y = mx + b, where m represents the slope. The given equation is y = 2x + 7, which means the slope is 2. To compare the rates of change, we compare the slopes. If the slopes are equal, the rates of change are equal. In this case, the slopes are equal to 2, so the rates of change are the same.

The function rule has a greater slope.

The slopes are equal.

In problem 3, we are told that as x increases by 1, y increases by 3. This information gives us the rate of change between x and y. The slope of a function represents the rate of change, and in this case, the slope is 3. Comparing the slopes, we find that they are equal, as both have a value of 3. Therefore, the rates of change are the same.
