2(2x + 3) + 5x + 1 = -11

Answer:2

Step-by-step explanation: To solve the equation -2 1/3x = -1 3/4, we need to isolate the variable x on one side and simplify the equation.

First, we need to convert both sides to have the same denominator. We can choose the least common multiple of 3 and 4, which is 12.

-2 1/3x = -1 3/4

-2 1/3 * 4/4 * x = -1 3/4 * 3/3

-8/3 x = -5 1/3

Next, we isolate x by dividing both sides by -8/3:

(-8/3) x / (-8/3) = -5 1/3 / (-8/3)

x = (5 1/3) / (8/3)

x = (5 1/3) * (3/8)

Finally, we simplify the fraction to get the final solution:

x = (5 1/3) * (3/8)

x = (5 * 3 + 1 * 3) / 8

x = 16 / 8

x = 2

Therefore, the solution to the equation -2 1/3x = -1 3/4 is x = 2.

The average amount of fluid consumed is 35.7 oz of fluid each day.

We have to note that in this case of the question, we have the following information;

When we convert the galloons to oz, we can see that the amounts of the milk and the water are actually 64 oz and 128 oz respectively.

Total fluid consumed in the week = 64 oz + 6 0z + 128 oz + 52 oz

Writing only p = 5 is a mistake since p = 0 is also a solution of the  quadratic equation

Given the quadratic equation: p² −5p = 0

p² −5p = 0

p(p−5) = 0

p = 0 or p−5=0    

p = 0 or p = 5

Jada made mistake in the  3rd step instead of him to break the equation into two parts and then equate them to zero i.e he neglected the part where p = 0 and only make use of p-5 = 0

Since the equation has two solutions, p = 0 and p = -5. Therefore, writing only p = 5 is a mistake because when p = 0 is substituted into p² −5p = 0, it also gives 0

The area under the curve to the right of 64 is 0.2514.

To find the area under the curve to the right of 64 in a normal distribution with mean μ = 60 and standard deviation σ = 6, follow these steps:

1. Calculate the z-score: z = (x - μ) / σ, where x = 64.
  z = (64 - 60) / 6
  z = 4 / 6
  z ≈ 0.67

2. Use a z-table or calculator to find the area to the left of z = 0.67.
  The area to the left of z = 0.67 is approximately 0.7486.

3. Subtract the area to the left from 1 to find the area to the right of z = 0.67.
  Area to the right = 1 - 0.7486
  Area to the right ≈ 0.2514

So, the area under the curve to the right of 64 in this normal distribution is approximately 0.2514.

Pakiso's fixed cost per day is R300, which covers the expense of hiring the bakkie.

To calculate Pakiso's fixed cost per day, we need to consider the expenses that do not vary with the number of loads of refuse taken to the dumping site. In this case, the fixed cost is the cost of hiring the bakkie, which is R300 per day.

Pakiso hires a bakkie for R300 per day, regardless of how many loads of refuse they take to the dumping site or how long they work. This cost remains constant, making it a fixed cost for Pakiso. Whether they take one load or multiple loads, the bakkie cost remains the same each day.

It's important to note that the cost of hiring Lilo is not part of the fixed cost since it varies with the number of loads taken to the dumping site. The variable cost associated with Lilo is R7 per load of refuse.

In summary, Pakiso's fixed cost per day is R300, which covers the expense of hiring the bakkie.

The 95% confidence interval based on the same data is 5.15 < μ < 6.05

Because it has a longer interval, the 95 percent confidence interval offers more details.

The likelihood that a parameter will fall between two values near the mean is shown by a confidence interval.

Confidence intervals quantify how certain or uncertain a sampling technique is.

Confidence intervals are used by statisticians to gauge the degree of uncertainty in a sample variable.

The 90% confidence interval is given by:

Mean - 1.645(S.D./\(\sqrt{n}\)) < μ < Mean + 1.645(S.D./\(\sqrt{n}\))

2μ = 5.22 + 5.98 = 11.2

μ = 11.2 / 2 = 5.6

Thus,

5.6 - 5.22 = 1.645(S.D./\(\sqrt{n}\)) = 0.38

S.D./\(\sqrt{n}\) = 0.38 / 1.645 = 0.231

The 95% confidence interval is given by:

Mean - 1.96(S.D./\(\sqrt{n}\)) < μ < Mean + 1.96(S.D./\(\sqrt{n}\))

=5.6 - 1.96(0.231) < μ < 5.6 + 1.96(0.231)

= 5.6 - 0.4528 < μ < 5.6 + 0.4528

= 5.15 < μ < 6.05

The 95% confidence interval provides more information because it has a larger interval.

Answer:

2x=50

Step-by-step explanation:

Hi there,

Your question is "twice a number (x) is fifty"

Recall how a number is represented by x.

Twice a number would be represented as 2x.

Therefore, to represent that twice a number is equal to 50, that would result in the expression: \(2x=50\)

If you're looking to solve this equation, it's often best to think about the "reverse" of the current equation.

Notice how 2 is multiplying the x.

To isolate x, divide that side by 2.

However, recall that whatever is done to one side of an equation must also be done to the other side of the equation. Therefore, you will need to divide both sides by 2.

\(2x=50\)

\(\frac{2x}{2} = \frac{50}{2}\)

\(x=25\)

Equation: \(2x=50\)

Solving for x: 25

Step-by-step explanation:

There is a 20% chance that you made a Type II error in your study with an alpha value of 0.05 and a power of 80%. This means that there is a 20% chance that you failed to detect a true effect or relationship in the population.

To calculate the chance of making a Type II error, we need to understand what Type II error is and how it relates to the alpha value and power of a study.

Type II error, also known as a false negative, occurs when we fail to reject the null hypothesis when it is actually false. In other words, it means we incorrectly conclude that there is no effect or relationship in the population, even though there is one.

The power of a study represents the probability of correctly rejecting the null hypothesis when it is indeed false. It is directly related to the probability of making a Type II error. Therefore, the chance of making a Type II error is equal to 1 minus the power of the study.

Given that the power of the study is 80% (or 0.80), the chance of making a Type II error can be calculated as follows:

Chance of making a Type II error = 1 - Power of the study
                                = 1 - 0.80
                                = 0.20 or 20%

Therefore, The p-value is the probability of obtaining a test statistic as extreme or more extreme than the observed value, assuming the null hypothesis is true. If the p-value is less than the significance level, reject the null hypothesis; otherwise, fail to reject it.

To find the p-value from the t statistic on TI-84, you will need to perform a hypothesis test. Here are the steps:1. Enter your data into the calculator and choose the appropriate test.2. Calculate the t statistic by dividing the sample mean by the standard error.3. Determine the degrees of freedom. This is n-1 for a one-sample t-test or n1+n2-2 for a two-sample t-test. 4. Use the t-distribution table to find the critical value for your test.5. Calculate the p-value using the t-distribution function on the calculator.6. Compare the p-value to the significance level (usually 0.05) to determine whether to reject or fail to reject the null hypothesis.7.

(a-1) The value of the population mean is unknown.

(a-2) The best estimate of the population mean is the sample mean, which is 20 eggs.

(c) The value of t for a 95% confidence interval with 17 degrees of freedom is approximately 2.110.

(d) the 95% confidence interval for the population mean is approximately (17.902, 22.098).

(e-1) It would not be reasonable to conclude that the population mean is 17 eggs.

(e-2) It would be reasonable to conclude that the population mean is 18 eggs.

(a-1) The given information provides the sample mean (20 eggs) and the sample standard deviation (5 eggs), but it does not directly provide the population mean.

(a-2) In the absence of other information, the sample mean is a reasonable estimate of the population mean.

(c) For a 95% confidence interval, the value of t can be determined using the t-distribution with n-1 degrees of freedom, where n is the sample size. In this case, the sample size is 18, so the degrees of freedom is 18 - 1 = 17.

Using a t-distribution table or a statistical software, the value of t for a 95% confidence interval with 17 degrees of freedom is approximately 2.110.

(d) To determine the 95% confidence interval for the population mean, we can use the formula: Confidence interval = sample mean ± (t * standard error), where the standard error is the sample standard deviation divided by the square root of the sample size.

In this case, the sample mean is 20, the standard deviation is 5, the sample size is 18, and the value of t is 2.110. Plugging in these values, the confidence interval is 20 ± (2.110 * (5 / √18)), which evaluates to approximately 20 ± 2.098.

(e-1) The 95% confidence interval calculated in part (d) does not include 17 eggs, indicating that it is unlikely for the population mean to be 17 eggs.

(e-2) The 95% confidence interval calculated in part (d) includes 18 eggs, suggesting that it is plausible for the population mean to be 18 eggs.
