If MSwithin is smaller than MSbetween, then increasing MSwithin and/or decreasing MSbetween will lead to an increase in the F statistic.

The F statistic is calculated by dividing the variance between groups (MSbetween) by the variance within groups (MSwithin). Therefore, to increase the value of the F statistic, either the numerator (MSbetween) needs to increase, or the denominator (MSwithin) needs to decrease.

So, the answer is:

a. MSwithin > MSbetween

If the variance within groups (MSwithin) is reduced or the variance between groups (MSbetween) is increased, the F statistic will increase. Therefore, if MSwithin is smaller than MSbetween, then increasing MSwithin and/or decreasing MSbetween will lead to an increase in the F statistic.

The length of XW from the given triangle XYZ is 671.16 units.

Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.

The formula for sine rule is sinA/a=sinB/b=sinC/c

Given that, in ΔXYZ, ∠X=17° and ∠Y=82°. ∠XWZ=90° and XY=700.

By using angle sum property,

∠X+∠Y+∠Z=180°

17°+82°+∠Z=180°

99°+∠Z=180°

∠Z=180°-99°

∠Z=81°

Now, YZ/sinX=XZ/sinY=XY/sinZ

YZ/sin17°=XZ/sin82°=700/sin81°

XZ/0.9902=700/0.9876

XZ/0.9902=708.78

XZ=701.83

Now, cos17°=XW/701.83

0.9563=XW/701.83

XW=0.9563×701.83

XW=671.16

Therefore, the length of XW is 671.16 units.

Step-by-step explanation:

so he got them for £10 all 24 bars, then he went and sold each for 50c, so hmmm 24 at £0.50 that's (24)(0.5) = 12, so he bought them for £10 and sold them for £12, he's got a surplus or profit of £2.

In this problem, we are dealing with a random variable related to people's opinions on a new building project. We are given four options for the correct wording of the random variable and need to determine the correct one. Additionally, we are asked to calculate probabilities associated with the number of people who favor the new building project, ranging from exactly 4 to at most 6.

a) The correct wording for the random variable is "rv = the number of people who are in favor of a new building project." This wording accurately represents the random variable as the count of individuals who support the project.

b) To calculate the probability that exactly 4 people favor the new building project, we need to use the binomial probability formula. Assuming the probability of a person favoring the project is p, we can calculate P(X = 4) = (number of ways to choose 4 out of 10) * (p^4) * ((1-p)^(10-4)). The value of p is not given in the problem, so this calculation requires additional information.

c) To find the probability that less than 4 people favor the new building project, we can calculate P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3). Again, the value of p is needed to perform the calculations.

d) The probability that more than 4 people favor the new building project can be calculated as P(X > 4) = 1 - P(X ≤ 4) = 1 - (P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)).

e) The probability that exactly 6 people favor the new building project can be calculated as P(X = 6) using the binomial probability formula.

f) To find the probability that at least 6 people favor the new building project, we can calculate P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10).

g) Finally, to determine the probability that at most 6 people favor the new building project, we can calculate P(X ≤ 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6).

The speed of the river's current is 0.4 miles per hour.

To determine the speed of the river's current, we can set up a system of equations based on the information given.

Let's denote the speed of the river's current as v miles per hour.

During the downstream leg of the triathlon, the participant swims with the current, so their effective speed is the sum of their swimming speed and the current's speed:

Effective speed downstream = 2 + v miles per hour

During the upstream leg, the participant swims against the current, so their effective speed is the difference between their swimming speed and the current's speed:

Effective speed upstream = 2 - v miles per hour

We are given that the total swim time is 1.25 hours. Since the participant swims the same distance both downstream and upstream, we can set up the following equation based on the time and distance relationship:

Time downstream + Time upstream = Total swim time

(1.2 miles) / (Effective speed downstream) + (1.2 miles) / (Effective speed upstream) = 1.25 hours

Substituting the expressions for the effective speeds, we have:

(1.2 miles) / (2 + v) + (1.2 miles) / (2 - v) = 1.25

To solve this equation, we can clear the denominators by multiplying both sides by (2 + v)(2 - v):

(1.2 miles)(2 - v) + (1.2 miles)(2 + v) = 1.25(2 + v)(2 - v)

Simplifying the equation:

2.4 - 1.2v + 2.4 + 1.2v = 1.25(4 - \(v^2\))

4.8 = 5 - 1.25\(v^2\)

Rearranging terms:

1.25\(v^2\) = 5 - 4.8

1.25\(v^2\) = 0.2

Dividing both sides by 1.25:

\(v^2\) = 0.2 / 1.25

\(v^2\) = 0.16

Taking the square root of both sides:

v = ± √0.16

Since the speed of the river's current cannot be negative, we take the positive square root:

v = 0.4

Therefore, the speed of the river's current is 0.4 miles per hour.

Probability of a successful call 0.3157 = 31.57%  

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will learn the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.

A probability is the number of desired outcomes divided by the number of total outcomes.

The odds of making a sale on a single call are 6 to 13.

This means that in 6+13 = 19 calls, 6 are successful.

Comparing the means of the two samples, we find that the difference between the means is significant. Therefore, we can reject the claim and conclude that male and female high school students have different exam scores.

To perform the two-sample t-test, we first calculate the standard error of the difference between the means using the formula:

SE = sqrt((s1^2 / n1) + (s2^2 / n2))

Where s1 and s2 are the population standard deviations of the male and female students respectively, and n1 and n2 are the sample sizes. Plugging in the values, we have:

SE = sqrt((47^2 / 49) + (4.3^2 / 53))

Next, we calculate the t-statistic using the formula:

t = (x1 - x2) / SE

Where x1 and x2 are the sample means. Plugging in the values, we have:

t = (239 - 21.1) / SE

We can then compare the t-value to the critical t-value at α = 0.01 with degrees of freedom equal to the sum of the sample sizes minus 2. If the t-value exceeds the critical t-value, we reject the null hypothesis.

In this case, the t-value is calculated and compared to the critical t-value using the provided standard normal distribution table. Since the t-value exceeds the critical t-value, we can reject the claim that male and female high school students have equal exam scores.

Therefore, the correct answer is:

B. Male and female high school students have different exam scores.

The numbers that cannot be probabilities are: square root of 2, -53, 5/3, and 1.31.

Probability is a measure of the likelihood of a particular event occurring in a random experiment. It is a value between 0 and 1, with 0 indicating that an event is impossible, and 1 indicating that an event is certain to occur.

In statistics, probability is used to make predictions or draw inferences about a population based on a sample of data. For example, if we were to flip a coin, the probability of getting heads is 0.5, or 50%. In general probability can be defined as the ratio of the number of favorable outcomes to the total number of possible outcomes, which is the mathematical framework behind the random experiments.

From the set of numbers, 0, 0.08, and 3/5 are all possible values of probability.

Therefore, square root of 2, -53, 5/3, and 1.31 cannot be probabilities.
