Answer:

Step-by-step explanation:

No, this is not correct.

Step 1: Find the directional distance from every vertex on the blue image to  the center, Point C.

Point A is 1 unit left and 4 units upwards to Point C.

Point B is 4 units right and 5 units upwards to Point C.

Point C is the center of the dilation, so that point will not change.

Step 2: Apply the scale factor to the directional distances to know the distances of the new images.

The scale factor is 2 so

Point A' should be 2 units left and 8 units upwards to Point C.

Point B' should 8 units right and 10 units upwards to Point C.

Step 3:  Move the point in respect to Point C.

The new image should have the these points.

One point that is 2 units left and 8 units upwards to Point C.

Another point that is Point B' should 8 units right and 10 units upwards to Point C.

One point that coincides  with  Point C.

A representative sample based on the hospital scenario is option A

A subset of a larger population that accurately reflects the traits, diversity, and distribution of the total population is referred to as a representative sample.

Due to time, financial, or logistical limitations, it is frequently not possible or practical to investigate an entire population when conducting research or gathering data. In these situations, researchers choose a representative sample from which to deduce generalizations about the total population.

The scenario that can be solved using a two-way data table out of the options provided is to display how the profit of a lemonade stand will change when the price per cup and the count per cup change.

A two-way data table is a useful tool for conducting sensitivity analysis and exploring how changing two input variables affects the output or result of a formula or calculation. In this case, the profit of a lemonade stand is the output variable, while the price per cup and the count per cup are the two input variables. By creating a two-way data table with different values for the price per cup and the count per cup, we can systematically analyze how these two factors impact the profit of the lemonade stand. Each combination of the price per cup and the count per cup will be evaluated, and the corresponding profit will be calculated. This analysis allows us to observe the relationship between the input variables (price per cup and count per cup) and the output variable (profit). We can identify the optimal price per cup and count per cup that maximize the profit or explore different scenarios to understand how changes in these variables affect the overall profitability of the lemonade stand. Therefore, the option "b. to display how the profit of a lemonade stand will change when the price per cup and the count per cup change" can be solved using a two-way data table.

No, the sample size of 48 observations is not adequate for the firm to be 99% confident that the standard time is within +5% of the true value.

To determine the proper sample size for the firm to be 99% confident that the standard time is within +5% of the true value, we need to calculate the required sample size using the formula for sample size determination.

The formula for sample size calculation is:

n = (Z * σ / E)^2

Where:

n = required sample size

Z = Z-score corresponding to the desired confidence level (99% confidence corresponds to Z = 2.58)

σ = standard deviation of the population

E = maximum allowable error (+5% of the true value, which corresponds to E = 0.05)

Given that the observed time has a standard deviation of 1.38 minutes, we can substitute the values into the formula and solve for the required sample size:

n = (2.58 * 1.38 / 0.05)^2

n = 194.09

Therefore, the proper number of observations should be 195 to achieve a 99% confidence level with a maximum allowable error of +5% of the true value. Since the current sample size is 48, it is not adequate to meet the desired level of confidence.

Answer:

If a tangent segment and a secant segment intersect outside a circle, then the square of the measure of the tangent segment equals the product of the measures of the secant segment and its external portion.

42^2 = (18 + x)(18)

1,764 = 18(x + 18)

x + 18 = 98

x = 80

So the diameter of the reservoir is 80 meters.

The diameter of the reservoir shown above can be calculated based on the intersecting secant-tangent theorem as: 80 meters.

A diameter is a straight line segment that crosses the center of a circle thereby connecting two points on its circumference and it is twice the length of the radius of a circle.

To find the diameter (x), apply the intersecting secant-tangent theorem which states that:

AB² = AC(x + CA)

Substitute:

42² = 18(x + 18)

1,764 = 18x + 324

1,764 - 324 = 18x

1,440 = 18x

1,440/18 = x

x = 80 meters.

Answer:

  B. cos(pi/2) +i·sin(pi/2)

Step-by-step explanation:

You can convert to rectangular and back, or you can use the trig function relations directly.

  w = 4·cis(π/2) = 4i

  z = 3·cis(3π/2) = -3i

Then the sum is ...

  w +z = 4i -3i = i = cis(π/2) . . . . matches choice B

__

An alternative representation of z is ...

  z = -3·cis(π/2)

Then ...

  w +z = 4·cis(π/2) -3·cis(π/2) = cis(π/2)

_____

Additional comment

In the above, we have used cis(α) to represent (cos(α) +i·sin(α)).

We use integration by parts with the formula:

∫u dv = uv - ∫v du

In this case, we choose:

u = ln(x), dv = x^4 dx

Then we have:

du = (1/x) dx

v = ∫x^4 dx = (1/5)x^5 + C

where C is the constant of integration.

Using the formula, we get:

∫x^4 ln(x) dx = u v - ∫v du

= ln(x) [(1/5)x^5 + C] - ∫[(1/5)x^5 + C] (1/x) dx

= ln(x) [(1/5)x^5 + C] - (1/25)x^5 - C ln(x) + C

= (1/5)ln(x) x^5 - (1/25)x^5 + C

Therefore, the integral of x^4 ln(x) dx is (1/5)ln(x) x^5 - (1/25)x^5 + C.

A statistically significant negative correlation coefficient of r = -0.91 was obtained from a sample of n = 30. This indicates a strong and significant negative relationship between the variables.

The researcher conducted a correlation analysis and found a correlation coefficient (r) of -0.91, which indicates a strong negative relationship between the variables under investigation. The negative sign indicates that as one variable increases, the other variable tends to decrease, and vice versa.

The statistical significance of the correlation coefficient is crucial in determining whether the observed relationship is likely to be due to chance or if it truly exists in the population. In this case, the report should highlight that the obtained correlation coefficient is statistically significant.

To establish statistical significance, the researcher likely conducted a hypothesis test, such as a t-test or a permutation test, to determine the probability of obtaining a correlation coefficient as extreme as -0.91 under the null hypothesis of no correlation. Since the obtained correlation coefficient is statistically significant, it suggests that the observed negative relationship is unlikely to be a result of chance and provides evidence for a genuine association between the variables in the population from which the sample was drawn.

Reporting this finding is important for conveying the strength and significance of the negative relationship to the readers, providing valuable insights for further analysis and interpretation of the variables under investigation.

The 4 cm dilation of any shape means transforming the shape into new image by multiplying it's area by 4cm.

A dilation is a transformation that enlarges or contracts a preimage to create a new figure (called the image). The scale factor, k, determines how large or small the dilation image is in comparison to the preimage.

When a dilation produces a larger image, this is referred to as enlargement.

When a dilation results in a smaller image, this is known as reduction.

The scale factor is defined as the ratio of the size of the new image to the size of the old image.

The image will stretch if the scale factor is greater than one.

If the scale factor is between [0 , 1] the image reduces.

The original and produced images are identical if the scale factor is one..

The 4cm dilation means dilating the area of any shape by scaling factor 4cm.

As the scaling factor is greater than 1 then the result of dilation will be a enlarged shape of the original shape.

Thus, dilation by 4 cm results in increasing the area of the shape.

In order to know if a triangle is a right triangle on a coordinate plane, you can find the lengths of all three sides of the triangle using the distance formula and apply the Pythagorean theorem.

Find the lengths of the three sides of the triangle using the distance formula.

Once you have the lengths of the sides, check if any of the three sides satisfy the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In other words, if a² + b² = c², where c is the longest side, then the triangle is a right triangle.

If one of the sides satisfies the Pythagorean theorem, then the triangle is a right triangle.
