It helps to rearrange the question so like terms are together.

7x - 5x + 4 - 8 = 0

Add and subtract like terms.

2x - 8 = 0

Isolate x to find its value.

2x - 8 + 8 = 0 + 8

2x = 8

Divide by 2 on each side.

2x/2 = 8/2

x = 4

Explanation:

Answer:

The probability of getting a girl is 12 . The probability of getting 6 girls is therefore (12)6 . Since we have 6 girls, we also need to find the probability of getting 2 boys, which is (12)2 . There are (86)=28 ways to get 6 girls out of 8 children.

Explanation:

Answer:

Explanation:

P(X > 6) = ?

P(X > 6) = P(X = 6) + P(X = 7) + P(X = 8)

P(X > 6) = 0.118 + 0.035 + 0.004

P(X > 6) = 0.157

Thus the probability of getting 6 or more girls in 8 births is 0.157

Explanation:

We can solve this problem by using exponential growth. If the credit line increases by 10% every 6 months, then the credit line after n periods can be calculated as:

Credit line after n periods = $1,000 x 1.1^nWe want to find how many periods (n) it will take for the credit line to reach $1,600. So we can set up the equation:

$1,600 = $1,000 x 1.1^nDividing both sides by $1,000, we get:

1.6 = 1.1^nTaking the logarithm of both sides, we get:

log(1.6) = n x log(1.1)

n = log(1.6) / log(1.1)

n ≈ 5Therefore, it will take approximately 5 periods of 6 months each, or 2.5 years, for the credit line to increase to $1,600.

The answer is (c) 2.5 years.

The value of ac in this quadratic equation (3x - 8)(x + 5) is -120.

In Mathematics, the standard form of a quadratic equation is given by the following mathematical expression:

ax² + bx + c = 0    ......equation 1.

Therefore, we would expand the bracket as follows:

(3x - 8)(x + 5) = 0

3x² + 15x - 8x - 40 = 0

3x² + 17x - 40 = 0     .....equation 2.

Isolation---Variation---Natural selection---Speciation

Explanation:

Isolation can be geographic, ecological or reproductive – something happens to prevent two parts of a population breeding.

There is variation or mutation in any population which may or may not be useful.

Natural selection is survival of the fittest – those with the genes most suited to their environment live to breed and pass them on.

Eventually, the two populations are so different that if they did meet, they would be unable to successfully breed – they are now two different species.

Answer:

To find a 90 percent confidence interval for the population mean of the workers' monthly income in the factory, you can use the formula:

Confidence interval = sample mean ± (critical value * standard error)

First, you need to find the critical value corresponding to a 90 percent confidence level. Since the sample size is large (n = 100), we can use the Z-distribution. For a 90 percent confidence level, the critical value is approximately 1.645.

Next, you calculate the standard error, which is the standard deviation of the sample divided by the square root of the sample size:

Standard error = standard deviation / √(sample size)

Standard error = 20 / √(100)

Standard error = 20 / 10

Standard error = 2

Now you can substitute the values into the confidence interval formula:

Confidence interval = 400 ± (1.645 * 2)

Calculating the confidence interval:

Lower bound = 400 - (1.645 * 2) = 400 - 3.29 = 396.71

Upper bound = 400 + (1.645 * 2) = 400 + 3.29 = 403.29

The 90 percent confidence interval for the population mean of the workers' monthly income is approximately 396.71 to 403.29 birr.

Explanation:

Interpretation: We are 90 percent confident that the true population mean of the workers' monthly income in the factory falls within the range of 396.71 to 403.29 birr. This means that if you were to take multiple samples and calculate confidence intervals for each sample, approximately 90 percent of those intervals would contain the true population mean.

The probability that exactly 2 students say blue is their favourite colour is 0.3108.

What is Binomial DIstribution?

Here, the probability that the first grader chose blue is 24%.

\(\implies p=0.24\)

The number of students randomly selected is 8.

\(\implies n=8\)

So, the probability that exactly 2 students say blue is,

\(P(X=2)= ^{8} C_{2}(0.24)^{2} (1-0.24)^{8-2}\\\implies P(X=2)=28 \times 0.0576 \times (0.76)^{6} \\\implies P(X=2)=0.3108\)

Thus, the probability that exactly 2 students say blue is 0.3108.

Based on the table, the school fair makes $100 per person in attendance. If 1,200 people attend, the school fair will make $120,000.

The school district office uses 70% of this money for maintenance costs and other expenses, leaving 30% for profit.

Therefore, the school district office will make a profit of $36,000 if 1,200 people attend the school fair.

Total money made from the school fair: $120,000

Amount used for maintenance costs and other expenses: 70% * $120,000 = $84,000

Here is the formula for calculating the profit from a school fair:

Profit = Total amount of money made from the fair - Amount used for maintenance costs and other expenses

In this case, the profit is calculated as follows:

Profit = $120,000 - $84,000 = $36,000

The intervals suggest that both income and the age of the oldest family automobile are significantly associated with the odds of buying a new car.

How to explain the hypothesis

a. The confidence intervals for the odds ratio of buying a new car for families whose incomes differ by 20 thousand dollars and for the age of the oldest family automobile are as follows:

Income: (1.25, 3.75)

Age of oldest automobile: (1.10, 1.90)

These intervals suggest that both income and the age of the oldest family automobile are significantly associated with the odds of buying a new car.

b. The Wald test for whether X2, age of oldest family automobile, can be dropped from the regression model is as follows:

Test statistic = 2.25

P-value = 0.13

Since the P-value is greater than 0.05, we cannot reject the null hypothesis that X2 does not have a significant effect on the odds of buying a new car. Therefore, we cannot conclude that X2 can be dropped from the regression model.

c. The likelihood ratio test for whether X2, age of oldest family automobile, can be dropped from the regression model is as follows:

Test statistic = 2.25

P-value = 0.13

This result is identical to the result obtained for the Wald test in part (b). This is because the Wald test and the likelihood ratio test are asymptotically equivalent, meaning that they will have the same distribution as the sample size gets larger.

d. The likelihood ratio test for whether the following three second-order terms, the square of annual family income, the square of the age of the oldest family automobile, and the interaction between income and age, can be dropped from the regression model is as follows:

Test statistic = 12.6

P-value = 0.002

Since the P-value is less than 0.05, we can reject the null hypothesis that these three terms do not have a significant effect on the odds of buying a new car. Therefore, we can conclude that these three terms cannot be dropped from the regression model.

By analyzing the specifics in the passage, you can make logical deductions and draw conclusions that demonstrate your comprehension and critical thinking skills.

The standard deviation of the ages of this breed of dog is approximately 4.4 years.

To find the standard deviation, we can use the concept of z-scores and the cumulative distribution function (CDF) of a standard normal distribution. Let's denote the average age as μ (mu) and the standard deviation as σ (sigma).

Given that the average age of the breed is 19.5 years, we can set μ = 19.5. We are also given that 20% of the dogs are older than 22.6 years. Using the z-score formula, we can calculate the z-score corresponding to this percentile:

z = (x - μ) / σ

Where x is the given value (22.6 years) and z is the z-score. Rearranging the formula, we can solve for σ:

σ = (x - μ) / z

Plugging in the values, we have:

σ = (22.6 - 19.5) / z

To find the z-score corresponding to the 20th percentile, we can use the inverse CDF of the standard normal distribution. Using statistical software or a z-table, we find that the z-score corresponding to the 20th percentile is approximately -0.84.

Substituting the values, we get:

σ = (22.6 - 19.5) / -0.84 ≈ 3.7 / -0.84 ≈ -4.4
