The parachutist started the free fall at a height of 68.12 meters above the ground.(b) The height at which the fall begins is 68.12 meters. The units of height are meters.

Given parameters: Initial velocity (u) = 0 m/s

           Final velocity (v) = 2.8 m/s

           Initial height (h) = ?

           Final height (s) = 65 m

Acceleration (a) = 2.4 m/s²Time taken (t) = ?

The formula for calculating the time taken in a free fall with an initial velocity is given by;

                                   v = u + at

Wherev = final velocityu = initial velocity

                       a = accelerationt = time taken

Rearranging the formula to get the time taken;

                       => t = (v - u) / a=> t = (2.8 - 0) / 2.4=> t = 1.17 seconds

(a) The parachutist is in the air for 1.17 seconds.

Since the parachutist starts from rest at a height (h) above the ground, her final velocity can be calculated using the formula;

                                 v² = u² + 2asWherev = final velocityu = initial velocitya = acceleration due to gravitys = height fallen

Rearranging the formula to get the initial height (h)

                                          ;=> h = s - u² / 2a

                                            => h = 65 - 0² / 2(2.4)

                                            => h = 68.12 meters (approx)

Therefore, the parachutist started the free fall at a height of 68.12 meters above the ground.(b) The height at which the fall begins is 68.12 meters. The units of height are meters.

Therefore, the answer in (a) is 1.17 seconds (s), while the answer in (b) is 68.12 meters (m).

Answer: Therefore, the correlation coefficient, r, is 0.877. This indicates a strong positive correlation between age and fundamental frequency in hyena giggles.

Step-by-step explanation:

To calculate the correlation coefficient, r, we need to follow these steps:

Step 1: Calculate the sum of squares of age.

Step 2: Calculate the sum of squares for fundamental frequency.

Step 3: Calculate the sum of products between age and frequency.

Step 4: Compute the correlation coefficient, r.

Here are the calculations:

Step 1: Calculate the sum of squares of age.

2^2 + 2^2 + 2^2 + 6^2 + 9^2 + 10^2 + 13^2 + 10^2 + 14^2 + 14^2 + 12^2 + 7^2 + 11^2 + 11^2 + 14^2 + 20^2 = 1066

Step 2: Calculate the sum of squares for fundamental frequency.

840^2 + 670^2 + 580^2 + 470^2 + 540^2 + 660^2 + 510^2 + 520^2 + 500^2 + 480^2 + 400^2 + 650^2 + 460^2 + 500^2 + 580^2 + 500^2 = 1990600

Step 3: Calculate the sum of products between age and frequency.

2840 + 2670 + 2580 + 6470 + 9540 + 10660 + 13510 + 10520 + 14500 + 14480 + 12400 + 7650 + 11460 + 11500 + 14580 + 20500 = 190080

Step 4: Compute the correlation coefficient, r.

r = [nΣ(xy) - ΣxΣy] / [sqrt(nΣ(x^2) - (Σx)^2) * sqrt(nΣ(y^2) - (Σy)^2))]

where n is the number of observations, Σ is the sum, x is the age, y is the fundamental frequency, and xy is the product of x and y.

Using the values we calculated in steps 1-3, we get:

r = [16190080 - (106500)] / [sqrt(162066 - 106^2) * sqrt(161990600 - 500^2)]

= 0.877

Therefore, the correlation coefficient, r, is 0.877. This indicates a strong positive correlation between age and fundamental frequency in hyena giggles.

Fixed costs are expenses that remain constant regardless of the level of production. The calculation of average fixed costs (AFC) is obtained by dividing the total fixed cost by the number of units produced.

AFC provides the amount per unit that the company will spend on fixed costs to produce a given quantity of output. Therefore, to calculate the average fixed cost at the Shanghai factory if the 2020 output level (= 35,000 cars annually) were maintained for ten years, we will first calculate the total fixed costs.

The formula for calculating average fixed cost (AFC) is:

Average Fixed Cost (AFC) = Total Fixed Cost / Quantity ProducedTotal Fixed Cost is obtained by multiplying the fixed cost per unit with the total number of units produced.

If he water in Earth’s oceans has a volume of about 3.2x10⁸ cubic miles, it would take 3.52x10²⁰ gallon jugs to hold all the water in Earth's oceans.

To calculate how many gallon jugs it would take to hold all the ocean water on Earth, we need to multiply the volume of the water by the conversion factor from cubic miles to gallons.

Given that the water in Earth's oceans has a volume of about 3.2x10⁸ cubic miles and there are about 1.1x10¹² gallons in 1 cubic mile, we can calculate the total number of gallons using the following equation:

Total gallons = (Volume in cubic miles) x (Gallons per cubic mile)

Substituting the given values, we get:

Total gallons = (3.2x10⁸) x (1.1x10¹²) = 3.52x10²⁰

This number is very large and is written in scientific notation to make it more manageable. Scientific notation is a compact way of writing very large or very small numbers using a power of ten. In this case, the number is expressed as a coefficient (3.52) multiplied by 10 raised to the power of 20 (10²⁰).

Step-by-step explanation:

first, you have to find the equation of the perpendicular bisector of this given line.  

to do that, you need the slope of the perpendicular line and one point.

Step 1: find the slope of the given line segment. We have the two end points (10, 15) and (-20, 5), so the slope is m=(15-5)/(10-(-20))=1/3

the slope of the perpendicular line is the negative reciprocal of the slope of the given line, m=-3/1=-3  

step 2: find the middle point: x=(-20+10)/2=-5, y=(15+5)/2=10      (-5, 10)

so the equation of the perpendicular line in point-slope form is (y-10)=-3(x+5)

now plug in all the given coordinates to the equation to see which pair fits:

(-8, 19): 19-10=9, -3(-8+5)=9, so yes, (-8, 19) is on the perpendicular line.

The correct system of equations that describes the situation is: 0.12x + 0.38y = 0.25(100) x + y = 100. Riley to make a 25% saline solution using the available 12% and 38% saline mixtures.

The problem states that Riley wants to make 100 ml of a 25% saline solution using 12% and 38% saline mixtures. To solve this problem, we need to set up a system of equations that represents the given conditions. Let x represent the amount of the 12% solution used, and y represent the amount of the 38% solution used.

The first equation in the system represents the concentration of saline in the mixture. We multiply the concentration of each solution (0.12 and 0.38) by the amount used (x and y, respectively) and add them together. The result should be equal to 25% of the total volume (0.25(100)) to obtain a 25% saline solution.

The second equation in the system represents the total volume of the mixture, which is 100 ml in this case. We add the amounts used from both solutions (x and y) to get the total volume.

By solving this system of equations, we can find the values of x and y that satisfy the given conditions and allow Riley to make a 25% saline solution using the available 12% and 38% saline mixtures.

The correct probabilities are P(at least two tails) = 0. 5 and P(at least one heads) = 0. 875.

Let's calculate the probabilities based on the given sample space:

Total number of outcomes (sample space) = \(2^{3}\) = 8

P(one tails):

From the sample space, there are four outcomes that have exactly one tails: HTT, THT, TTH, TTT.

So, P(one tails) = 4/8 = 0.5

P(three heads):

From the sample space, there is only one outcome that has three heads: HHH.

So, P(three heads) = 1/8 = 0.125

P(one heads and two tails):

From the sample space, there are three outcomes that have one heads and two tails: HHT, HTH, THH.

So, P(one heads and two tails) = 3/8 = 0.375

P(at least two tails):

From the sample space, there are four outcomes that have at least two tails: TTH, THT, HTT, TTT.

So, P(at least two tails) = 4/8 = 0.5

P(at least one heads):

From the sample space, there are seven outcomes that have at least one heads: HHH, HHT, HTH, THH, THT, TTH, TTT.

So, P(at least one heads) = 7/8 = 0.875

Therefore, the correct probabilities are:

P(one tails) = 0.5

P(three heads) = 0.125
