The correct expression representing the value stored in the variable x after executing the given program is: a. 2*3*3*3 This is because the program starts with x having a value of 2 and then multiplies x by 3 four times in a row.

The expression that represents the value stored in the variable x as a result of executing the program is option D: 24*4*4*4. This is because the program starts with the x being assigned the value 2, and then the instruction "XX * 3" is executed 4 times.

This means that the value of x is multiplied by 3, four times in a row. So, the final value of x will be 2 * 3 * 3 * 3 * 3, which simplifies to 24 * 4 * 4 * 4.

Answer:

150 cal

Step-by-step explanation:

5x30=150

Answer:

150 calories.

Step-by-step explanation:

Assuming there is the same amount of chocolate as well as cookie dough throughout the whole cookie.

You know that 1/5 of a chocolate chip cookie has 30 calories.

Find one cookie, by multiply 5 to both numbers. Set the equation:

1/5x = 30

Isolate the variable. Multiply 5 to both sides:

(1/5x) * 5 = (30) * 5

x = 30 * 5

x = 150

150 calories is your answer.

The total movement of the unicycle is given as follows:

39.6 m.

The circumference of a circle of radius r is given by the equation presented as follows:

C = 2πr.

The diameter for this problem is given as follows:

d = 0.7m.

The radius is half the diameter, hence it's length is given as follows:

r = 0.35m.

18 compete rotations means that the total distance is 18 times the circumference of the circle, hence:

18 x 2π x 0.35 = 39.6 m.

For a symmetric distribution, the left whisker extends from the median to the minimum value in the dataset.

The left whisker represents the lower values or the lower tail of the distribution. It is also referred to as the "lower whisker" or the "whisker on the left side". The length of the left whisker may vary depending on the spread or range of the data.

In a box plot or box-and-whisker plot, the left whisker represents the lower values or the lower tail of the distribution. It indicates the range of values that lie below the median. The length of the left whisker is determined by the spread or range of the data.

If the data has a smaller range and is more tightly clustered around the median, the left whisker will be shorter. This indicates that the lower values in the dataset are relatively close to the median. On the other hand, if the data has a larger range and is more spread out, the left whisker will be longer. This suggests that the lower values in the dataset are more dispersed or spread out from the median.

Step-by-step explanation:

Answer:

1. y=18, x=25 2. y=5, x=-4

Step-by-step explanation:

For the first one, you have to find what x or y equals, and I chose x. x would equal y+7. Then I just plugged in x to the other equation and solved for y. After finding y, 18, I plugged it back into the first equation and got 18+7=25. I did the same steps for the 2nd one as well.

This integral will give us the desired area of the region bounded by the curve f(x) = 25 - x^2 and the x-axis within the interval [-5, 5].

To calculate the area of the region bounded by the curve f(x) = 25 - x^2, we can set up a definite integral over the desired interval.

The function, f(x) = 25 - x^2, represents a downward-opening parabola centered at the origin with a vertex at (0, 25).

To get  the area, we need to consider the portion of the curve that lies above the x-axis. This corresponds to the region we want to find the area of.

Since the curve is symmetric about the y-axis, we can focus on the positive x-values.

To determine the interval, we need to get the x-values where the curve intersects or touches the x-axis. Solving the equation 25 - x^2 = 0 gives x = ±5.

Therefore, the interval we are interested in is [-5, 5], which represents the portion of the curve above the x-axis.

The definite integral that yields the area of the region is:

∫[from -5 to 5] (25 - x^2) dx

Evaluating this integral will give us the desired area of the region bounded by the curve f(x) = 25 - x^2 and the x-axis within the interval [-5, 5].

The volume of the box is 3,189,068 cubic centimeters. The length, width, and height of a large, custom-made shipping crate are 1.22 m, 3.22 m, and 0.83 m, respectively. What is the volume of the box (in cm)? The volume of a box is calculated by multiplying the length, width, and height of a box.

However, the dimensions are given in meters, not centimeters, so they must first be converted. The given dimensions are as follows: Length = 1.22 m, Width = 3.22 m, Height = 0.83 m.

To convert meters to centimeters, multiply each dimension by 100. As a result, the dimensions will be as follows:Length = 122 cmWidth = 322 cmHeight = 83 cm.

Now, using the formula, Volume = Length x Width x Height= 122 x 322 x 83= 3,189,068 cubic centimeters. Therefore, the volume of the box is 3,189,068 cubic centimeters.

No, the presence of an effect does not necessarily imply that error variance will go away.

The presence of an effect does not necessarily imply that error variance will go away. In fact, error variance is an inherent part of any statistical model and represents the amount of variation in the response variable that is not explained by the predictor variables.

Even if a predictor variable has a significant effect on the response variable, there may still be some unexplained variation in the response that is attributable to error variance.

It is important to take into account and control for error variance in any statistical analysis, as it can affect the precision and accuracy of the estimates of the model parameters and can also influence the interpretation of the results.

One way to control for error variance is to use appropriate statistical methods, such as analysis of variance (ANOVA), regression analysis, or other modeling techniques that take into account the variability in the data.

The correct answer is d. 155. We need a whole number for the sample size, we round up to the nearest whole number.

Therefore, the required sample size is approximately 155.

To determine the sample size needed for a z-test with 95% power and a significance level of 0.05, we can use power analysis. Given the following hypotheses and parameters:

H0: μ = 10 (null hypothesis)

HA: μ ≠ 10 (alternative hypothesis)

σ = 6.9 (standard deviation)

Desired power (1 - β) = 0.95

Significance level (α) = 0.05

We can use a power analysis formula to calculate the required sample size:

n = [(Zα/2 + Zβ) × σ / (μ0 - μA)]²

Where:

Zα/2 is the critical value for a two-tailed test at a significance level of α/2.

Zβ is the critical value corresponding to the desired power.

Let's calculate the required sample size:

Zα/2 = Z(0.05/2) = Z(0.025) ≈ 1.96 (from the standard normal distribution table)

Zβ = Z(0.95) ≈ 1.645 (from the standard normal distribution table)

n = [(1.96 + 1.645) × 6.9 / (10 - 12)]²

n ≈ [3.605 × 6.9 / -2]²

n ≈ [-24.870 / 2]²

n ≈ -12.435²

n ≈ 154.51

Since we need a whole number for the sample size, we round up to the nearest whole number.

Therefore, the required sample size is approximately 155.

Answer:

p = 7

Step-by-step explanation:

(x² + px - 3)(3x - 5)

each term in the second factor is multiplied by each term in the first factor, that is

x²(3x - 5) + px(3x - 5) - 3(3x - 5) ← distribute parenthesis

= 3x³ - 5x² + 3px² - 5px - 9x + 15 ← collect like terms

= 3x³ +x²(3p - 5) - x(5p + 9) + 15

given the coefficient of the x- term is - 44 , then

-(5p + 9) = - 44 ← - (5p + 9) is th coefficient of x in the expansion

- 5p - 9 = - 44 ( add 9 to both sides )

- 5p = - 35 ( divide both sides by - 5 )

p = 7
