Write the ratio for sin a!!!! thanks!! The first person to answer I will mark brainliest!!!

Step-by-step explanation:

Let k be Kevin’s age and let d be Daniel’s age.

Given : Kevin is 3 years older than Daniel.

i.e. k=d+3

Kevin's age two years ago= k-2

Two years ago, Kevin was 4 times as old as Daniel.

i.e. k-2=4(d-2)

Hence, the system of equations represents this situation :

k=d+3

k-2=4(d-2)

The estimated size of the deer population in the area is approximately 36.43. Since this is less than the carry capacity of 95, no permits need to be issued for population control.

To estimate the size of the deer population, we can use the mark and recapture method. The biologist tagged 28 deer in June and then trapped a total of 60 deer in August, of which 17 had tagged ears.

The mark and recapture method assumes that the proportion of tagged deer in the second sample represents the proportion of tagged deer in the entire population. We can set up a proportion:

(Tagged deer in the second sample) / (Total population) = (Tagged deer in the first sample) / (Total number of deer in the second sample)

Using the given information:

17 / Total population = 28 / 60

To solve for the total population, we can cross-multiply and solve the equation:

17 * 60 = 28 * Total population

1020 = 28 * Total population

Total population = 1020 / 28

Total population ≈ 36.43

Therefore, the estimated size of the deer population in that area is approximately 36.43.

To determine if any permits should be issued, we need to compare the estimated population size to the carry capacity of 95. Since the estimated population size is less than the carry capacity, no permits need to be issued.

Since η² ≈ 0.33 and not 0.50, the statement "If an analysis of variance produces SS between = 20 and SS within = 40, then η² = 0.50" is false.

ANOVA, or Analysis of Variance, is a statistical method used to compare the means of two or more groups to determine if there are any statistically significant differences between them. It is commonly used in experimental and observational studies to analyze the variance between group means and within-group variability.

ANOVA tests the null hypothesis that the means of the groups are equal, against the alternative hypothesis that at least one of the group means is different. It calculates the F-statistic, which compares the between-group variability to the within-group variability. If the F-statistic is large enough and exceeds a critical value, it indicates that there is evidence to reject the null hypothesis and conclude that there are significant differences between the group means.

We can determine if η² = 0.50 is true or false by calculating the effect size η² using the provided SS between and SS within values.
η² = SS_between / (SS_between + SS_within)
η² = 20 / (20 + 40)
η² = 20 / 60
η² = 1/3 ≈ 0.33

True, the eta-squared value is indeed 0.50, indicating that 50% of the total variance is accounted for by the between-group variation.

The formula to calculate eta squared (η2) is:
η2 = SSbetween / (SSbetween + SSwithin)
If SSbetween = 20 and SSwithin = 40, then:
η2 = 20 / (20 + 40) = 0.5
Therefore, η2 = 0.50, which means that 50% of the total variance in the dependent variable can be attributed to the independent variable (or factor) being analyze. The statement "If an analysis of variance produces SS between = 20 and SS within = 40, then η 2 = 0.50" is true. To determine η 2 (eta-squared), you'll need to calculate the proportion of total variance explained by the between-group variation. This can be done using the formula η 2 = SS between / (SS between + SS within). In this case, η 2 = 20 / (20 + 40) = 20 / 60 = 0.50. Therefore, the eta-squared value is indeed 0.50, indicating that 50% of the total variance is accounted for by the between-group variation.

The probability of having 7 out of 10 people with O negative blood type can be calculated using the binomial probability formula. The likelihood of selecting 7 O negative blood donors out of a group of 10.

To calculate the probability, we can use the binomial probability formula: P(X = k) = C(n, k) * p^k * (1 - p)^(n - k), where P(X = k) represents the probability of getting exactly k successes, n is the total number of trials, p is the probability of success in each trial, and C(n, k) is the binomial coefficient, which represents the number of ways to choose k items from a set of n items.

In this case, we want to find the probability of having 7 O negative blood donors out of 10, given that the probability of any individual having O negative blood type is 55% (or 0.55).

Plugging in the values into the binomial probability formula, we have:

P(X = 7) = C(10, 7) * (0.55)^7 * (1 - 0.55)^(10 - 7)

Calculating the binomial coefficient, we have:

C(10, 7) = 10! / (7! * (10 - 7)!) = 120

Substituting the values into the formula, we get:

P(X = 7) = 120 * (0.55)^7 * (0.45)^3

Evaluating this expression gives us the probability that 7 out of 10 people have O negative blood type.

If 15 students wore jeans, then 9 students wore shorts based on the given ratio of 5:3.

To determine the number of students who wore shorts, we can use the given ratio of students who wore jeans to students who wore shorts, which is 5:3.

Let's assume that the number of students who wore shorts is represented by x. According to the ratio, the number of students who wore jeans is 5.

Now, we can set up a proportion using the ratio:

5/3 = 15/x

To solve for x, we can cross-multiply:

5x = 3 * 15

5x = 45

Dividing both sides of the equation by 5:

x = 45/5

x = 9

a.The probability that a randomly selected watch will be in working condition for more than five years is approximately 6.68%. b.Approximately 93.32% of the watches will be in operating condition after the warranty period. c. The maximum life expectancy of the middle 95% of the watches is approxiamately 63.68 months. d.The range of the middle 95% of the watches is from 32.32 months to 63.68 months. The range represents 95% of the watches, it means that 5%.

a. To find the probability that a randomly selected watch will be in working condition for more than five years, we need to convert the time to the same unit as the distribution. Since the mean is given in years and the standard deviation is given in months,

we need to convert five years to months.

Mean = 4 years = 4 x 12 months = 48 months

Standard deviation = 8 months

To calculate the probability, we need to find the area under the normal distribution curve to the right of 60 months (5 years).

Using a standard normal distribution table or a calculator, we can find the z-score corresponding to 60 months:

z = (x - μ) / σ

z = (60 - 48) / 8 = 12 / 8 = 1.5

The probability can be found by looking up the z-score in the standard normal distribution table or using a calculator. From the table or calculator, we find that the probability is approximately 0.0668, or 6.68%.

b. The warranty period for Timely brand watches is three years. To find the percentage of watches that will be in operating condition after the warranty period, we need to find the probability that a randomly selected watch will last longer than three years.

We need to convert three years to months:

Warranty period = 3 years = 3 x 12 months = 36 months

We calculate the z-score:

z = (x - μ) / σ

z = (36 - 48) / 8 = -12 / 8 = -1.5

Using the standard normal distribution table or a calculator, we find the area to the left of -1.5 is approximately 0.0668. The probability that a randomly selected watch will not last longer than three years is approximately 0.0668.

To find the percentage of watches that will be in operating condition after the warranty period, we subtract this probability from 1 (since we want the complementary probability):

Percentage = 1 - 0.0668 = 0.9332 = 93.32%

c. The middle 95% of the watches represents the range within which 95% of the watches' life expectancy falls. To find the minimum and maximum life expectancy of this range, we need to determine the z-scores that correspond to the cumulative probability of 0.025 and 0.975.

For the minimum life expectancy (lower bound), we look up the z-score that corresponds to a cumulative probability of 0.025. This z-score is approximately -1.96.

z = -1.96

Using the z-score formula, we can find the corresponding value in months:

x = μ + (z x σ)

x = 48 + (-1.96 * 8) = 48 - 15.68 = 32.32

The minimum life expectancy of the middle 95% of the watches is approximately 32.32 months.

For the maximum life expectancy (upper bound), we look up the z-score that corresponds to a cumulative probability of 0.975. This z-score is also approximately 1.96.

z = 1.96

Using the z-score formula, we can find the corresponding value in months:

x = μ + (z x σ)

x = 48 + (1.96 x 8) = 48 + 15.68 = 63.68

d. Ninety-five percent of the watches refer to the range between the 2.5th and 97.5th percentiles. We already calculated the z-scores corresponding to these percentiles in part c: -1.96 and 1.96.

To find the range in months,

we convert the z-scores back:

\(x_{1}\)= μ +\(z_{1}\) x σ = 48 + (-1.96) x 8 = 32.32 months,

and \(x_{2}\)= μ + \(z_{2}\) x σ

= 48 + 1.96 x 8

= 63.68 months.

Answer:

The solution to the system of equations is:

(x, y) = (-2, 36)

Therefore, the x-coordinate of the solution of the system

x = -2

Step-by-step explanation:

Given the system of equations

\(\begin{bmatrix}x+y=34\\ x-y=-38\end{bmatrix}\)

subtracting the equations

\(x-y=-38\)

\(-\)

\(\underline{x+y=34}\)

solve -2y for y

\(-2y=-72\)

Divide both sides by -2

\(\frac{-2y}{-2}=\frac{-72}{-2}\)

\(y=36\)

For x+y=34 plug in y = 36

\(x+36=34\)

Subtract 36 from both sides

\(x+36-36=34-36\)

Since the candy is in the shape of a triangular pyramid, we can use the formula for the volume of a pyramid:

Volume of pyramid = (1/3) x base area x height

We know the height of the candy is 12 mm, and the volume of the candy is 204 mm³. So we can rearrange the formula to solve for the base area:

base area = (3 x Volume of pyramid) / (height)

base area = (3 x 204 mm³) / (12 mm)

base area = 51 mm²

Therefore, the area of the base of the candy is 51 mm².

Answer: the value of x is 34.

Step-by-step explanation: Let's start by finding the mode of the set of integers. The mode is the number that appears most frequently in the set.

From the given integers, we can see that x appears twice, and all other numbers appear only once. Therefore, the mode is x.

Now we are told that the mean of the set is 1.5 times the mode. We can set up an equation to represent this:

(mean) = 1.5 * (mode)

To find the mean, we can add up all the numbers in the set and divide by the total number of integers:

(mean) = (31 + 58 + 98 + x + x) / 5

Simplifying the expression on the right:

(mean) = (187 + 2x) / 5

Substituting this expression for the mean into our equation:

(187 + 2x) / 5 = 1.5x

Multiplying both sides by 5 to eliminate the fraction:

187 + 2x = 7.5x

Subtracting 2x from both sides:

187 = 5.5x

Dividing both sides by 5.5:

x = 34

Therefore, the value of x is 34.
