Answer:

\(\sin(50^o) = \frac{3}{c}\)

Step-by-step explanation:

Given

See attachment for triangle

Required

Expression to solve c

To solve for c, we simply calculate the sine of angle at B

i.e.

\(\sin(50^o) = \frac{Opposite}{Hypotenuse}\)

This gives:

\(\sin(50^o) = \frac{3}{c}\)

Make c the subject

\(c = \frac{3}{\sin(50^o)}\)

Step-by-step explanation:

The range in which 95% of the scores lie is between 75 and 95.

According to the Empirical Rule: For a normal distribution, approximately 68% of the data falls within 1 standard deviation of the mean, approximately 95% of the data falls within 2 standard deviations of the mean, and approximately 99.7% of the data falls within 3 standard deviations of the mean.

So, about 95% of the scores lie between 75 and 95. T

This is because the mean score is 85 and one standard deviation is 5, so one standard deviation below the mean is 80 (85-5) and one standard deviation above the mean is 90 (85+5).

Two standard deviations below the mean are 75 (85-2*5) and two standard deviations above the mean is 95 (85+2*5).

Therefore, the range in which 95% of the scores lie is between 75 and 95.

The length of the deep end is 12 feet of the swimming pool.

Given: Area of the swimming pool is 210 square feet

Width of the pool = 10 feet

The length of the shallow end is 9 feet and the length of the deep end is d.

To find the value of d.

Let's solve the problem.    

The area of the swimming pool is 210

The width is 10

The deep end length is d

The shallow end length is 9

The total length of the swimming pool = The length of the deep end + The length of the shallow end

=> d + 9

Therefore, the total length of the swimming pool is d + 9

The surface of the swimming pool is rectangular, so

The area of rectangle = width × length

Therefore,

area of swimming pool = width of the pool × length of the swimming pool

=> 210 = 10 × (9 + d)

or 10 × (9 + d) = 210

Dividing both sides by 10:

10 × (9 + d) / 10 = 210 / 10

9 + d = 21

Subtracting 9 on both sides:

9 + d - 9 = 21 - 9

d = 12

Therefore the length of the deep end is 12 feet

Hence the length of the deep end is 12 feet of the swimming pool.

The length of the deep end of the swimming pool is 12 feet.

We are given that:

The Area of the swimming pool = 210 square feet

width of the swimming pool = 10 feet

Length of shallow end = 9 feet

Let the length of the deep end be d.

Total length of the swimming pool = length of deep end + length of shallow end =  d + 9

Area of swimming pool = width × length

Substituting the values, we get that:

210 = 10 × (9 + d)

9 + d = 21

d = 12

Therefore the length of the deep end of the swimming pool is 12 feet.

To find the coefficients of the power series representation of f(x) = ln(10-x), we can use the Taylor series expansion. The general formula for the coefficients of a power series is given by:

c_n = f^(n)(a) / n!

where f^(n)(a) represents the nth derivative of f(x) evaluated at a.

For the function f(x) = ln(10-x), let's calculate the first few coefficients:

c_0 = f(0) = ln(10-0) = ln(10)

c_1 = f'(0) = -1 / (10-0) = -1/10

c_2 = f''(0) = 0

c_3 = f'''(0) = 2 / (10^3) = 1/500

c_4 = f''''(0) = 0

Since the derivative of f(x) is zero for all terms beyond the third derivative, the coefficients c_2, c_4, and so on, are zero.

Therefore, the coefficients of the power series are: c_0 = ln(10), c_1 = -1/10, c_2 = 0, c_3 = 1/500, c_4 = 0. To find the radius of convergence R of th series, we can use the ratio test or other convergence tests. In this case, since the function f(x) = ln(10-x) is defined for all x such that 10-x > 0, we have x < 10. Hence, the radius of convergence is R = 10.

The answer is A. The normal distribution in its standardized form has a mean of 0 and a standard deviation of 1. This means that the distribution is centered around 0, and the spread of the data is determined by the standard deviation of 1. This is useful in statistical analysis because it allows us to compare data from different distributions on a standardized scale.

The normal distribution is a continuous probability distribution that is often used in statistical analysis. It is characterized by a bell-shaped curve and is symmetrical around its mean. In its standardized form, the normal distribution has been transformed to have a mean of 0 and a standard deviation of 1. This transformation is achieved by subtracting the mean of the distribution from each data point and dividing by the standard deviation. This standardization allows us to compare data from different normal distributions on a standardized scale.

The normal distribution has many properties that make it useful in statistical analysis. It is often used as a model for many real-world phenomena, such as the distribution of human height, IQ scores, and many others. The normal distribution is also useful because it is well understood and has many mathematical properties that make it easy to work with.

Answer:

The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50

Step-by-step explanation:

Let,

x be the price per pound of walnuts

y be the price per pound of chocolate chips

According to given statement,

4x+8y=25     Eqn 1

2x+3y=10      Eqn 2

Multiplying Eqn 2 by 2

2(2x+3y=10)

4x+6y=20    Eqn 3

Subtracting Eqn 3 from Eqn 1

(4x+8y)-(4x+6y)=25-20

4x+8y-4x-6y=5

2y=5

Dividing both sides by 2

\(\frac{2y}{2}=\frac{5}{2}\\y=2.50\)

Putting y=2.50 in Eqn 2

2x+3(2.50)=10

2x+7.50=10

2x=10-7.50

2x=2.50

Dividing both sides by 2

\(\frac{2x}{2}=\frac{2.50}{2}\\x=1.25\)

Hence,

The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50

For a penetrated confined aquifer:

(a) Pressure:

The pressure can be calculated using the hydrostatic pressure formula:

Pressure = density × gravity × height

Given:

Density of water = 1000 kg/m³ (assuming water density)

Acceleration due to gravity = 9.8 m/s²

Height above the confined aquifer = 8.8 m

Using the formula:

Pressure = 1000 kg/m³ × 9.8 m/s² × 8.8 m

Pressure ≈ 86,240 N/m²

(b) Pressure Head:

The pressure head is the height equivalent of the pressure. Calculate by dividing the pressure by the product of the density of water and acceleration due to gravity:

Pressure Head = Pressure / (density × gravity)

Using the values:

Pressure Head = 86,240 N/m² / (1000 kg/m³ × 9.8 m/s²)

Pressure Head ≈ 8.8 m

(c) Elevation Head:

The elevation head is the difference in height between the top of the confined aquifer and the reference level (sea level). Given that the top of the confined aquifer is 545 m above sea level, the elevation head is 545 m.

(d) Hydraulic Head:

The hydraulic head is the sum of the pressure head and the elevation head:

Hydraulic Head = Pressure Head + Elevation Head

Hydraulic Head = 8.8 m + 545 m

Hydraulic Head ≈ 553.8 m

(e) Velocity of Water:

To calculate the velocity of water, Bernoulli's equation. However, to determine if the velocity term is significant, compare it to the pressure term. Assume a value for the flow rate and see if the resulting velocity is significant.

Assuming a flow rate of 1 m³/s, calculate the cross-sectional area of the well casing:

Area = π × (diameter/2)²

Area = π × (0.10 m/2)²

Area ≈ 0.00785 m²

Using the equation for flow rate: Q = velocity × Area, rearrange it to solve for velocity:

Velocity = Q / Area

Velocity = 1 m³/s / 0.00785 m²

Velocity ≈ 127.39 m/s

Considering a significant velocity term to be equal to or greater than 1% of the pressure term, check if the velocity (127.39 m/s) is 1% or more of the pressure term (86,240 N/m²):

Percentage of velocity term = (Velocity / Pressure) × 100

Percentage of velocity term = (127.39 m/s / 86,240 N/m²) × 100

Percentage of velocity term ≈ 0.15%

The velocity term (0.15%) is significantly smaller than 1% of the pressure term. Therefore, the velocity term can be considered insignificant.

In terms of realism, a flow rate of this magnitude (1 m³/s) is not typical for groundwater flow. Groundwater flow rates are generally much lower, usually on the order of liters per second or even less.
