The probability that a 6 occurs on exactly one of the rolls after rolling a fair die four times is 0.385.

The Three Kinds of Probability

Classical: (equally probable outcomes) (equally probable outcomes) Let S be the sample space (the collection of all unique outcomes that might occur).

Subjective Probability. Definition of Relative Frequency.

Formula used to find probability

The probability is often defined as the proportion of positive outcomes to all outcomes in the sample space. It is written as, the likelihood of an event

P(E) = (Number of favorable outcomes) ÷ (Sample space).

As die is rolled 4 times ,

X≈ binomial(4, 1/6)

P(X=r) = nCr (p)^r (q)^(n-r)

P(X = 1) = 4C1 × (1/6)^1 × (5/6)^3

           = 4 × 1/6 × (5/6)^3

∴P(X = 1) = 0.257

The option that  correctly describes the graph of the relationship is; D: A line that goes through (0, 0) and (4.5, 13.5)

The formula for the slope between two coordinates is;

Slope = (y₂ - y₁)/(x₂ - x₁)

Let us take two coordinates from the table which are;

(2.4, 7.2) and (4.5, 13.5)

Thus;

Slope = (13.5 - 7.2)/(4.5 - 2.4)

Slope = 3

Now, looking at the options, the first 3 cannot be correct because they have mixed up x-coordinate values with y-coordinate values.

Let us check the last option which is a line that goes through (0, 0) and (4.5, 13.5). Thus;

Step-by-step explanation:

To make the equation AFGHACBD true, the value of y must be 7, and the value of z must be 32-1=31.

Here is how the equation works out:

2z + 14 = 2 * 31 + 14 = 68

2y + 35 = 2 * 7 + 35 = 49

68 + 2 = 70

70 > 49

49 + 7y = 49 + 7 * 7 = 98

98 > 70

70 + 32 - 1 = 70 + 31 = 101

101 > 98

98 + 2y + 35 = 98 + 2 * 7 + 35 = 146

146 > 101

So, the values of y and z that make the equation AFGHACBD true are y=7 and z=31.

Answer:

x  =  -7 + √(73)

y  =  -7 - √(73)

Step-by-step explanation:

Product p = x × y = -24

Somme s = x + y = -14

Then

x and y are solutions to the equation:

z² - sz + p = 0

Then

x and y are solutions to the equation:

z² + 14z - 24 = 0

Using the quadratic formula:

x  =  ( -14 + √[(14² - 4×(1)×(-24)] ) / ( 2×(1) )  =  -7 + √(73)

and

y  =  ( -14 - √[(14² - 4×(1)×(-24)] ) / ( 2×(1) )  =  -7 - √(73)

Based on the information provided, it does not seem like this game is fair. Since region 1 and region 2 are the same size, each player has an equal chance of winning, but since region 3 is significantly larger than the other regions, neither player has a high chance of winning. This means that one player could potentially win multiple times in a row just by luck, without the other player having a chance to catch up. In order for the game to be considered fair, the relative sizes of the regions should be such that each player has a roughly equal chance of winning.

Answer:

Step-by-step explanation:

The slope of y = 7x - 10 is 7 while the y-intercept is -10 thus it has a high slope but a lower y-intercept so option (D) is correct.

A straight line on the coordinate plane is represented by a linear function.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

A linear function with slope m and y-intercept c is given as y = mx + c.

Compare the given function y = 7x - 10

Slope m  = 10

y-intercept = -10

Hence "Y = 7x - 10 has a slope of 7 and a y-intercept of -10, meaning it has a high slope but a low y-intercept".

Answer:

a= 108 degrees

b=88 degrees

c= 90 degrees

d= 90 degrees

Step-by-step explanation:

For a degrees since 72 degrees and a degrees make a straight angle:

180-72= a

So, a=108 degrees

Same goes for b degrees:

180-92=b

So, b=88 degrees

For c degrees, you need to know that the sum of the angles in a quadrilateral equal to 360 degrees.

So, 74+a+b+c=360

= 360- (74+108+88)=c

= 90 degrees= c

So since d degrees and c degrees make a straight angle,

180-90=d

90 degrees= d

The value of y of the inequality 4y + 1/5 ≤ 4/5 is: y ≤ 3/20.

Inequalities can be solved the way a normal algebraic equation is being solved. It is solved by isolating the value of the variable.

The inequality given is, 4y + 1/5 ≤ 4/5. Solve as shown below:

In this case, with four treatment groups and n = 12 participants in each group, dfwithin treatments would be equal to 3, because there are 4 - 1 = 3 treatment groups.

In a one-factor ANOVA, dfwithin treatments refers to the degrees of freedom within the treatment groups, which is a measure of the amount of variability that is present within each group.

The degrees of freedom within the treatment groups is used to calculate the mean square within treatments (MSwithin), which is a measure of the variability within each group. MSwithin is calculated by dividing the sum of the squared differences between each participant's score and the group mean by dfwithin. This value is then used to determine the statistical significance of the treatment effects, by comparing it to the mean square between treatments (MSbetween), which is a measure of the variability between the treatment groups.

In a one-factor ANOVA, the total degrees of freedom is equal to the number of participants in all of the groups combined (4 groups * 12 participants per group = 48) minus the number of groups (48 - 4 = 44). The degrees of freedom between treatments is equal to the number of groups minus 1 (4 - 1 = 3), and the degrees of freedom within treatments is equal to the total degrees of freedom minus the degrees of freedom between treatments (44 - 3 = 41).

So, the insurance company should be concerned that they could potentially lose money.

To test whether the insurance company should be concerned about the true mean claim amount being higher than the original estimate of $1,800, we can perform a one-sample t-test.

The null hypothesis for this test is that the true mean claim amount is equal to the original estimate of $1,800, and the alternative hypothesis is that the true mean claim amount is greater than the original estimate.

The t-statistic for this test is calculated as follows:

t = (sample mean - null mean) / (standard deviation / sqrt(sample size))

Plugging in the values from the problem, we have:

t = ($1,950 - $1,800) / ($500 / sqrt(40)) = 2.5.

We can then use a t-table or a computer to find the critical value of t for a one-tailed t-test with 39 degrees of freedom and a significance level of 0.05. The critical value is 1.68.

Since the calculated t-value of 2.5 is greater than the critical value, we can reject the null hypothesis and conclude that the true mean claim amount is significantly greater than the original estimate of $1,800.

Therefore, the insurance company should be concerned that they could potentially lose money.

Mean = 95.125

Variance = 198.90625

Standard deviation = 14.06,

Confidence interval = 95.125 +/- 3.45

To find the 95% confidence interval of the mean score for all bowlers in this league, we need to first calculate the sample mean and sample standard deviation of the given data set.

The sample mean is calculated as follows:

mean = 95.125

The sample standard deviation is calculated as follows:

First, we need to calculate the variance of the data set, which is done by taking the sum of the squared differences between each score and the mean, and dividing by the sample size minus 1:

variance = 198.90625

The sample standard deviation is then the square root of the variance:

standard deviation = sqrt(198.90625)

standard deviation = 14.06

Now that we have the sample mean and sample standard deviation, we can use these values to calculate the 95% confidence interval of the mean score for all bowlers in this league.

We can use the following formula to calculate the confidence interval:

confidence interval = mean +/- (1.96 * (standard deviation / sqrt(sample size)))

Substituting in the values we calculated above, we get:

confidence interval = 95.125 +/- (1.96 * (14.06 / sqrt(40)))
