Answer:

Speed= 500ml/hr

total distance= 2800 m

total time = d/t

2800/500= 5.6hrs

Step-by-step explanation:

(a) This is an observational study.

The reason is that the researchers did not manipulate any variables or conditions; they simply observed and collected data on the two groups of babies (VLBW and normal birth weight) as they grew up.
(b) The p-value (0.0013) is less than the significance level (typically 0.05), we reject the null hypothesis.  

There is sufficient evidence to suggest that the graduation rate among the VLBW group is significantly lower than the normal-birth-weight controls.

To determine if the graduation rate among the VLBW group is significantly lower than the normal-birth-weight controls, we can perform a hypothesis test using the proportion of high school graduates in each group.
State the null and alternative hypotheses.
Null hypothesis (H0):

There is no significant difference in graduation rates between the VLBW group and the control group ([tex]p_VLBW = p_control).[/tex]
Alternative hypothesis (Ha):

The graduation rate among the VLBW group is significantly lower than the control group [tex](p_VLBW < p_control).[/tex].

Calculate the sample proportions and the pooled proportion.
[tex]p_VLBW[/tex] = 179/242 = 0.7397
[tex]p_control = 193/233 = 0.8283.[/tex]

A circle is a geometric shape consisting of all the points in a plane that are a fixed distance (called the radius) away from a given point (called the center).

BLANK 1: To solve this problem, we can use the formula for the area of a sector of a circle, which is A = (θ/360)π[tex]r^2[/tex], where θ is the central angle of the sector, r is the radius of the circle, and π is pi (approximately 3.14).

BLANK 2: To find the area of sector HIJ, we need to know the radius of circle I and the measure of angle HIJ. From the given information, we know that circle I has a radius of 8, and angle HIJ is 45 degrees. Therefore, the area of sector HIJ is:

A = (45/360) x 3.14 x [tex]8^2[/tex]

A = 3.14 x 8 x (45/360)

A = 3.14 x 8 x 0.125

A = 2.51 square units (rounded to two decimal places)

Therefore, the area of sector HIJ is 2.51 square units.

BLANK 3: We know that sector KLM has the same area as sector HIJ, and circle L has a radius of 10. Therefore, we can use the formula for the area of a sector of a circle again to find the measure of angle KLM. Let x be the measure of angle KLM in degrees. Then:

A = (x/360) x 3.14 x [tex]10^2[/tex] = 2.51

Simplifying this equation gives:

(x/360) = 2.51/(3.14 x [tex]10^2[/tex])

(x/360) = 0.0008

x = 360 x 0.0008

x = 0.288

Therefore, the measure of angle KLM is approximately 0.29 degrees (rounded to two decimal places).

the coefficient of determination is 0.7, indicating that the independent variables explain 70% of the variation in the dependent variable.

The coefficient of determination, also known as R-squared, is a measure of how well the independent variables explain the variation in the dependent variable. It is calculated as the ratio of the explained variation to the total variation.

In this case, SST (total sum of squares) is 800 and SSE (error sum of squares) is 240. Therefore, the explained sum of squares (SSE) is 800 - 240 = 560.

The coefficient of determination is then calculated as:

R-squared = explained variation / total variation

R-squared = 560 / 800

R-squared = 0.7

The statement is sometimes true.

Supplementary angles are two angles whose measures add up to 180 degrees. So if x and y are supplementary angles, then:

The probability of a bulb lasting between 547 and 580 hours is approximately 0.0392

To solve this problem, we first need to standardize the values using the formula

z = (x - μ) / σ

where

x is the value we want to find the probability for,

μ is the mean, and

σ is the standard deviation.

In this case, we want to find the probability that a bulb will last between 547 and 580 hours, so we need to find the z-scores for these values.

z1 = (547 - 530) / sqrt(625) = 1.72

z2 = (580 - 530) / sqrt(625) = 2.8

Next, we use a standard normal distribution table or calculator to find the probabilities for each z-score. For example, using a calculator, we can find that

P(z1 < Z < z2) = P(1.72 < Z < 2.8) ≈ 0.0392

The sine function that describes the child's apparent distance from the center of the merry-go-round is d(t) = 5.3 sin(2π/15 * t)

To write a sine function that describes the child's apparent distance from the center of the merry-go-round as a function of time t, we can start by finding the amplitude, period, and phase shift of the motion.

Amplitude:

The amplitude of the motion is half the diameter of the merry-go-round, which is 10.6/2 = 5.3 feet. This is because the child moves back and forth across the diameter of the merry-go-round.

Period:

The period of the motion is the time it takes for the child to complete one full cycle of back-and-forth motion, which is equal to the time it takes for the merry-go-round to complete one full rotation.

From the given information, the child completes 8 rotations in 120 seconds, so the period is T = 120/8 = 15 seconds.

Phase shift:

The phase shift of the motion is the amount of time by which the sine function is shifted horizontally (to the right or left).

In this case, the child starts at one end of the diameter and moves to the other end, so the sine function starts at its maximum value when t = 0. Thus, the phase shift is 0.

With these values, we can write the sine function that describes the child's apparent distance from the center of the merry-go-round as:

d(t) = 5.3 sin(2π/15 * t)

where d is the child's distance from the center of the merry-go-round in feet, and t is the time in seconds. The factor 2π/15 is the angular frequency of the motion, which is equal to 2π/T.

According to the information, the surface area of the first prism is 795 cm², sencond prism is 843 in², and the cylinder is 3775.87 mm²

To find the surface area of two triangular prisms, we need to add the surface area of each prism. We can use the formula we found in the previous question to calculate the surface area of each triangular prism:

Surface area of first triangular prism = 2(0.5 x base x height) + perimeter x height

where base is the width of the triangular face, height is the height of the triangular face, and perimeter is the sum of the lengths of the three sides of the triangular face.

In this case, the first triangular face has a base of 9 cm, a height of 16 cm, and a perimeter of (9+15+12)=36 cm. Therefore, the area of each triangular face is:

0.5 x 9 cm x 16 cm = 72 cm²

The rectangular faces have dimensions of 9 cm x 15 cm, 15 cm x 16 cm, and 9 cm x 16 cm. Therefore, the area of each rectangular face is:

9 cm x 15 cm = 135 cm²

15 cm x 16 cm = 240 cm²

9 cm x 16 cm = 144 cm²

The total surface area of the first triangular prism is:

2(72 cm²) + (135 cm² + 240 cm² + 144 cm²) = 795 cm²

Similarly, for the second triangular prism, we have:

Surface area of second triangular prism = 2(0.5 x base x height) + perimeter x height

where base is the width of the triangular face, height is the height of the triangular face, and perimeter is the sum of the lengths of the three sides of the triangular face.

In this case, the second triangular face has a base of 8 in, a height of 15 in, and a perimeter of (8+15+20)=43 in. Therefore, the area of each triangular face is:

0.5 x 8 in x 15 in = 60 in²

The rectangular faces have dimensions of 8 in x 21 in, 15 in x 21 in, and 8 in x 15 in. Therefore, the area of each rectangular face is:

8 in x 21 in = 168 in²

15 in x 21 in = 315 in²

8 in x 15 in = 120 in²

The total surface area of the second triangular prism is:

2(60 in²) + (168 in² + 315 in² + 120 in²) = 843 in²

Therefore, the surface area of two triangular prisms is:

795 cm² + 843 in² = 795 cm² + (843 in² x 6.452 cm²/in²) ≈ 5508 cm²

For the cylinder, we can use the formula we found in the previous question to calculate the surface area:

Surface area of cylinder = 2πr² + 2πrh

where r is the radius of the circular face, h is the height of the cylinder.

In this case, the radius is 14 mm and the height is 29 mm. Therefore, the surface area of the cylinder is:

2π(14 mm)² + 2π(14 mm)(29 mm) = 2π(14 mm)(43 mm) ≈ 3775.87 mm²

Therefore, the surface area of two triangular prisms and a cylinder is approximately:

5508 cm² + 3775.87 mm² = 5508 cm² + (3775.87 mm² x 0.01 m²/mm²) ≈ 5885.47 cm²
