Answer:

9x+4<22

Explanation:

Inequalities are solved in the same way as normal equations, we just need to start by isolating the x term on one side so we can solve for it on the other side, which we can do by doing the same thing to both sides to cancel out the other term and the coefficient:

10 -2 > 4x +2 -2

8 > 4x

8/4 > 4x/4

2 > x

This means x can be anything less than 2.

So now we can find the maximum value for the equation by substituting x:

9(2) + 4 = 22

That is the maximum value if x is 2, but because x has to be less than two, the possible range of values for 9x+4 will all be less than 22.

9x+4<22

Answer:

To calculate the standard deviation of the distribution, we first need to find the expected value of X, which is the average number of girls in the 8 possible outcomes.

Since each child can be either a boy or a girl with equal probability, there are 2^3 = 8 possible outcomes for the number of boys and girls. We can list these outcomes and the corresponding number of girls:

BBB (0 girls)

BBG (1 girl)

BGB (1 girl)

BGG (2 girls)

GBB (1 girl)

GBG (2 girls)

GGB (2 girls)

GGG (3 girls)

To find the expected value of X, we add up the number of girls in each outcome and divide by the total number of outcomes:

E(X) = (0 + 1 + 1 + 2 + 1 + 2 + 2 + 3) / 8 = 1.5

Next, we need to calculate the variance of X. The variance is the expected value of the squared deviation from the mean:

Var(X) = E[(X - E(X))^2]

We can calculate this by finding the squared deviation from the mean for each possible outcome, multiplying by the probability of that outcome, and summing over all outcomes:

Var(X) = [(0 - 1.5)^2 / 8 + (1 - 1.5)^2 / 4 + (2 - 1.5)^2 / 4 + (3 - 1.5)^2 / 8]

= 0.65625

Finally, the standard deviation is the square root of the variance:

SD(X) = sqrt(Var(X)) = sqrt(0.65625) = 0.81 (rounded to two decimal places)

Interpretation: The standard deviation of the distribution of the number of girls in a family of three children is 0.81. This means that on average, the number of girls in such families is 1.5, but the actual number of girls can vary by up to 0.81 from this average.

Note that the probability that in our sample of 2518 people there are less than 598 people with type O blood is approximately 0.8508.

To find the mean number of people with type O blood in a sample of 2518 people, we multiply the sample size by the proportion of people with type O blood:

mean = 2518 x 0.23 = 578.14 (rounded to 2 decimal places)

To find the standard deviation of the number of people with type O blood, we can use the formula for the standard deviation of a binomial distribution:

standard deviation = sqrt(np(1-p)) = sqrt(2518 x 0.23 x 0.77) = 19.19 (rounded to 2 decimal places)

To use the normal approximation to find the probability that in our sample there are less than 598 people with type O blood, we need to standardize the value using the mean and standard deviation:

z = (598 - 578.14) / 19.19 = 1.04 (rounded to 2 decimal places)

Using a standard normal table or calculator, we can find the probability that z is less than 1.04:

P(z < 1.04) = 0.8508 (rounded to 4 decimal places)

Therefore, the probability that in our sample of 2518 people there are less than 598 people with type O blood is approximately 0.8508.

Henry David Thoreau wrote a collection of 18 articles titled Walden, or, Life in the Woods, which were first published in 1854.

The book served as a chronicle of Thoreau's experiment in simple life on the northern side of Walden Pond in eastern Massachusetts and was a significant addition to New England Transcendentalism (1845–47).

Walden is regarded as both a significant work of nature writing as well as a philosophical dissertation on work, leisure, independence, and individualism. It is regarded as Thoreau's finest achievement.

Thoreau wrote Walden during the two and a half years that he spent semi-alone at Walden Pond close to Concord, Massachusetts. He constructed a modest cabin on property owned by his friend Ralph.

The confidence interval of the mean is 24.845 < μ < 27.555

The results are not very different

Confidence interval is the range of values for which which is expected to have the values at a certain percentage of the times.

Given data form the question

99% confidence interval

167 randomly selected students

mean sample = 26.2

Standard deviation = 6.8

Definition of variables

confidence level, CL = 99%

mean sample, μ = 26.2

standard deviation, SD = 6.8

sample size, n = 167

since it random variable: t - distribution

degree of freedom = 167 - 1 = 166

significance level, α = 1 – confidence level = 1 - 0.99 = 0.01

The formula for the confidence interval is given by

CI = μ ± t ( SD / √n )

plugging the values

CI = 26.2 ± 2.606 ( 6.8 / √167 )

= 26.2 - 2.606 ( 6.8 / √167 )   OR    26.2 + 2.606 ( 6.8 / √167 )

= 24.828    OR     27.571    

The confidence interval is 24.828 < μ < 27.571

from the confidence interval 24.6 hg < μ < 28.4 hg

n = 14 sample

μ = 26.5 ​hg

SD =2.3 ​hg

26.5 - 24.6 = 28.4 - 26.5 = 1.9

1.9 = t * SD / √n

t = 1.9 * √14 / 2.3 = 3.091

from the t distribution table 3.091 = 0.002 significance level

1 - 0.002 = 0.998

Answer:

Explanation:

a) The mean of the population is given by:

Mean = (1 + 3 + 5 + 7) / 4 = 4

Therefore, the mean of the population is **4**.

b) There are six possible samples of two that can be drawn from the population:

{1,3}, {1,5}, {1,7}, {3,5}, {3,7}, {5,7}

The mean of each sample is:

{1,3}: (1+3)/2 = 2

{1,5}: (1+5)/2 = 3

{1,7}: (1+7)/2 = 4

{3,5}: (3+5)/2 = 4

{3,7}: (3+7)/2 = 5

{5,7}: (5+7)/2 = 6

Therefore, the means of all possible samples are:

2, 3, 4, 4, 5, 6

c) The sample mean of all possible samples can be calculated as follows:

Sample mean = (2 + 3 + 4 + 4 + 5 + 6) / 6 = 24 / 6 = 4

The sample mean is equal to the population mean. This is because the sample size is small and all possible samples have been considered. In general, as the sample size increases and more samples are considered, the sample mean will approach the population mean .

To dissolve a solute in a solvent quickly, Zora should shake it repeatedly.

Shaking the mixture or stirring it vigorously promotes the interaction between the solute and solvent molecules, increasing their chances of coming into contact and facilitating the dissolution process. This agitation helps in breaking down the solute particles and dispersing them evenly throughout the solvent, thereby accelerating the dissolution rate.

Decreasing the pressure or decreasing the surface area would not have a significant impact on the dissolution process. Pressure and surface area primarily affect the rate of dissolution for gases or solid particles exposed to the solvent, but they are not applicable in all scenarios.

Placing the mixture in a refrigerator would slow down the dissolution process rather than speed it up. Lowering the temperature decreases the kinetic energy of the molecules, reducing their movement and the overall rate of dissolution.

Answer:

The computer-controlled system would likely be better than the manual system used by the publishing company in several ways:

Precision: The computer-controlled system would be more precise and accurate than manual cutting. It can measure and cut the paper rolls with greater accuracy, reducing the likelihood of errors or waste.

Efficiency: The computer-controlled system can cut the paper rolls faster and more efficiently than manual cutting. This would increase the productivity of the workers and enable the company to produce more products in less time.

Consistency: The computer-controlled system would ensure consistent quality of the cut paper rolls. This is because the machine is programmed to cut the paper in the exact same way every time, which means that there is less room for human error or variation.

Safety: The computer-controlled system would be safer for the workers than manual cutting. It reduces the risk of injury from accidents or repetitive strain injuries associated with manual cutting.

Overall, the computer-controlled system would provide significant benefits for the publishing company in terms of precision, efficiency, consistency, and safety.
