The equals sign directive (=) is not used for both integer constants and string constants i.e., the given statement is false.

The equals sign directive (=) is used for assigning values or expressions to variables in programming languages. It is not used to define string constants.

In programming, the equals sign (=) is typically used as an assignment operator to assign a value or an expression to a variable.

For example, in languages like C, C++, Java, and Python, we use the equals sign (=) to assign values to variables. Integer constants, also known as literals, can be assigned using the equals sign, such as int x = 5; assigns the value 5 to the variable x.

On the other hand, string constants or string literals are typically enclosed in quotation marks. In most programming languages, double quotes ("") are used to represent string constants.

For example, string name = "John"; assigns the string "John" to the variable name.

Therefore, the equals sign directive (=) is not used for both integer constants and string constants.

It is specifically used for assigning values to variables, while string constants are represented using quotation marks.

The main answer to this question is that there could be several reasons why an experiment may not produce significant results even if the research hypothesis is true.

One possible explanation could be that the sample size used in the experiment was too small, which could have resulted in insufficient statistical power to detect the true effect of the independent variable on the dependent variable. Another explanation could be that there were extraneous variables that were not controlled for in the experiment, which could have influenced the results and made it difficult to detect the true effect of the independent variable.

it is important to consider all possible factors that may affect the results of an experiment and to take steps to minimize their impact. This includes ensuring that the sample size is appropriate, controlling for extraneous variables, and using appropriate statistical tests to analyze the data. By doing so, researchers can increase the likelihood of obtaining significant results that accurately reflect the effects of the independent variable on the dependent variable.

the probability that the mean life of a random sample of 9 bread-making machines falls between 6.4 and 7.2 years is: 0.6106.

We can use the central limit theorem to approximate the sampling distribution of the sample mean of bread-making machines, which is also normally distributed with a mean of 7 years and a standard deviation of 1/√9 = 1/3 years.

Then, we need to standardize the values of 6.4 and 7.2 using the formula:

z = (x - μ) / σ

where x is the value of interest, μ is the mean, and σ is the standard deviation.

For 6.4 years:

z1 = (6.4 - 7) / (1/3) = -1.2

For 7.2 years:

z2 = (7.2 - 7) / (1/3) = 0.6

We want to find the probability that the sample mean falls between 6.4 and 7.2 years, which is equivalent to finding the probability that the standardized sample mean falls between z1 and z2.

Using a standard normal distribution table or calculator, we can find the probabilities associated with each z-value:

P(z < -1.2) = 0.1151

P(z < 0.6) = 0.7257

Therefore, the probability that the mean life of a random sample of 9 bread-making machines falls between 6.4 and 7.2 years is:

P(-1.2 < z < 0.6) = P(z < 0.6) - P(z < -1.2) = 0.7257 - 0.1151 = 0.6106

The probability is approximately 0.6106 or 61.06%.

The area of the pool is 600 square units rounded to the tens place.

The area of the symmetrical pool in the water park can be determined by finding the product of its length and width. From the given figure, it appears that the length of the pool is approximately 30 units and the width is approximately 20 units.

To find the area, we multiply the length and width:

Area = length × width

Area = 30 units × 20 units

Area = 600 square units

Rounding to the tens place means we want to round the area to the nearest multiple of 10. In this case, the area of 600 square units would round to 600.

Therefore, the area of the pool rounded to the tens place is 600 square units.

To summarize:

- The length of the pool is approximately 30 units.
- The width of the pool is approximately 20 units.
- The area of the pool is 600 square units rounded to the tens place.

Answer:

D. 48

Step-by-step explanation:

y=10x-2 is our equation

If x is 5, then multiply 10 by 5. You get 50.

Subtract 2 from that. You get 48.

Answer:

D, 48

Step-by-step explanation:

Given x=5, plug x into y=10x-2

First you should plug the given x into the x in the equation. And put () around it.

y=10(5)-2

Now you multiply 10 by 5 and you get 50.

y=50-2

Now the last step is to subtract 2 from 50 which you will end up getting y=48. So the answer is y=48 which is letter D.

The appropriate conclusion is that the test would also be rejected at the level α=0.10, but we cannot make a decision for other significance levels.

If I conduct a statistical test of hypotheses and find that the null hypothesis is statistically significant (or simply is rejected) at the significance level α=0.05, the appropriate conclusion is that:Option (c) the test would also be rejected at the level α=0.10.However, we can not conclude that the test would also be rejected at other significance levels, for example, we can not make a decision for other significance levels.The null hypothesis (H0) is rejected if the probability of observing a value as extreme as that calculated from the sample data is very low, that is, less than or equal to the chosen level of significance (alpha).We choose a significance level before conducting the test, which is the level of risk that we are willing to accept when rejecting the null hypothesis.In this case, the null hypothesis is rejected at a significance level of 0.05, and it means that there is strong evidence against the null hypothesis, so we reject it and accept the alternative hypothesis. This decision only applies to this significance level and not to others.Therefore, the appropriate conclusion is that the test would also be rejected at the level α=0.10, but we cannot make a decision for other significance levels.

37°, 39° and 104°.

Step-by-step explanation:

In a triangle, all the 3 angles sum up to 180°.

3a + 8a + 37 = 180

11a = 180 - 37

11a = 143

a = 13

Angle 1 = 37

Angle 2 = 3a

= 3 × 13

= 39°

Angle 3 = 8a

= 8 × 13

= 104°

So, the angles are 37°, 39° and 104°.

Range is determined by using the largest number and the smallest number in a set of integers and subtracting them. Jesse's highest number was 24, and his lowest would be 10. 24-10=14.

Barbara's highest score was 22, while her lowest was 12. 22-12=10.

The inverse of the function (1/2)^x/3

Given function,

y = 3\(log_{1/2}\) x

Now,

y = 3\(log_{1/2}\) x

Let y = f(x)

then,

x = \(f^{-1} (y)\)

Now put \(f^{-1} (y)\) in the place of x,

y = 3\(log_{1/2}\) \(f^{-1} (y)\)

Simplifying,

y/3 = \(log_{1/2} f^{-1} (y)\)

\(f^{-1} (y) = 1/2^{y/3}\\\)

Replace y variable with x,

\(f^{-1} (x)\) = \((1/2)^{x/3}\)

Hence the inverse of function is \((1/2)^{x/3}\) .
