The y-intercept of the graph of the function f(d) would represent 7 and a reasonable domain to plot the growth function is 0 ≤ d ≤ 18 because the number of days is a whole number.

Part A: When the biologist concluded her study, the radius of the algae was approximately 13,29 mm.

What is a reasonable domain to plot the growth function?The given equation is,f(d) = 7(1.06)d

The radius of the algae was approximately 13.29 mm, which is the value of f(d).Thus, f(d) = 13.29

Substitute this value in the equation to find the value of d.13.29 = 7(1.06)dlog(13.29/7)/log(1.06) = dd = 17.19

Hence, a reasonable domain to plot the growth function is 0 ≤ d ≤ 18 because the number of days is a whole number.

Part B: What does the y-intercept of the graph of the function f(d) represent?The y-intercept of the graph of the function f(d) represents the initial value of the function when x = 0. The given function is,f(d) = 7(1.06)d

Substitute 0 in the above function and solve for f(0).f(0) = 7(1.06)0f(0) = 7

Hence, the y-intercept of the graph of the function f(d) represents 7.

(a) The mgf of Y is M_Y(t) = exp (3.54t + 0.01632t²).

(b) The distribution of Y, the total weight of the three 1-kilo packs of cheese selected is Y ~ N(3.54, 0.216).

(c) The probability P(Y < W) = 0.2808.

(a) The moment generating function (mgf) of Y, the total weight of the three 1-kilo packs of cheese selected is given by:

M_Y(t) = M_X1(t) × M_X2(t) × M_X3(t)

= exp (µ_X1 t + ½ σ²_X1 t²) × exp (µ_X2 t + ½ σ²_X2 t²) × exp (µ_X3 t + ½ σ²_X3 t²)

= exp [(µ_X1 + µ_X2 + µ_X3) t + ½ (σ²_X1 + σ²_X2 + σ²_X3) t²]

Therefore, the mgf of Y is given by:

M_Y(t) = exp [(1.18 + 1.18 + 1.18) t + ½ (0.072 + 0.072 + 0.072) t²]

M_Y(t) = exp (3.54t + 0.01632t²)

(b) The total weight Y of the three 1-kilo packs of cheese is the sum of three independent and identically distributed random variables.

So, the distribution of Y is given by the following normal distribution: Y ~ N (µ_Y, σ²_Y), where µ_Y = µ_X1 + µ_X2 + µ_X3 and σ²_Y = σ²_X1 + σ²_X2 + σ²_X3.

Thus, µ_Y = 3 × 1.18

µ_Y = 3.54 and,

σ²_Y = 3 × 0.072

σ²_Y = 0.216

⇒ σ_Y = √0.216

⇒ σ_Y = 0.4649

Therefore, Y ~ N(3.54, 0.216).

(c) We need to find P(Y < W), where W is the weight of the 3-kilo pack of cheese.

Now, Y and W are independent normal random variables.

Therefore, Y - W is also a normal random variable with the following distribution: Y - W ~ N(µ_Y - µ_W, σ²_Y + σ²_W), where µ_W = 3.22 and σ²_W = 0.09².

We know that µ_Y - µ_W = 3.54 - 3.22

µ_Y - µ_W = 0.32 and,

σ²_Y + σ²_W = 0.216 + 0.09² = 0.301.

Therefore, σ_Y - W = √0.301

σ²_Y + σ²_W = 0.5486.

Now, we need to find P(Y - W < 0), which is equivalent to finding P(Z < -0.5799), where Z = (Y - W - (µ_Y - µ_W))/σ_Y - W.

Substituting the values, we get:

Z = (Y - W - 0.32)/0.5486

⇒ Y - W = -0.5799

Z = (Y - W - 0.32)/0.5486

⇒ Y - W < 0 is equivalent to Z < -0.5799.

Using a standard normal table or calculator, we get: P(Z < -0.5799) = 0.2808.

Hence P(Y < W) = P(Y - W < 0)

P(Y < W) = 0.2808.

Therefore, P(Y < W) = 0.2808, correct to four decimal places.

Answer:

Hours driven= 40 hours

Step-by-step explanation:

Giving the following information:

Variable income= $21.6 per hour

Fixed income= $250

Total income= $1,114

To calculate the number of hours driven, we need to use the following formula:

Total income= fixed income + hourly rate*number of hours

1,114 = 250 + 21.6*x

864 = 21.6x

864 / 21.6 = x

40=x

Hours driven= 40 hours

To evaluate the double integral over the region in the first quadrant enclosed by a circle and lines by changing to polar coordinates, we need to express the integral limits and the integrand in terms of polar coordinates.

The region in the first quadrant enclosed by a circle and lines can be defined as follows: The circle has a radius 'r' centered at the origin, and the lines are given by the equations θ = 0 and θ = π/4, where θ represents the angle in polar coordinates.

In polar coordinates, the limits of integration for 'r' would be from 0 to the radius of the circle, and the limits of integration for θ would be from 0 to π/4.

The integrand, which represents the function being integrated, would be expressed in terms of 'r' and θ.

To evaluate the double integral, we would integrate the function over the defined region using the limits of integration and the appropriate differential element in polar coordinates, which is r dr dθ.

Using the midpoint rule with the given value of n, we can approximate the integral. The answer, rounded to four decimal places, will be explained in the following paragraphs.

The midpoint rule is a numerical method used to approximate definite integrals. It involves dividing the interval of integration into n subintervals of equal width and evaluating the function at the midpoint of each subinterval. The approximated value of the integral is obtained by summing the products of the function values at the midpoints and the width of each subinterval.

To calculate the integral using the midpoint rule, we need to know the value of n, which determines the number of subintervals. The larger the value of n, the more accurate the approximation becomes. However, increasing n also requires more computational effort.

Once we have determined the value of n, we divide the interval of integration into n subintervals of equal width. Then, we evaluate the function at the midpoint of each subinterval and multiply it by the width of the subinterval. Finally, we sum up all these products to obtain the approximate value of the integral.

Rounding the answer to four decimal places ensures that the approximation is presented with a reasonable level of precision. It is important to note that while the midpoint rule provides a reasonable estimate, it may not always yield an exact result due to the inherent limitations of numerical methods for integration.

No, the population does not have to be normally distributed to test the hypothesis in this scenario. The correct answer is OB. No, because n >= 30.

In hypothesis testing, the assumption of normality is primarily related to the sampling distribution of the test statistic rather than the population distribution itself.

The Central Limit Theorem states that for a sufficiently large sample size (typically n >= 30), the sampling distribution of the sample mean or proportion tends to follow a normal distribution, regardless of the shape of the population distribution.

In this case, the sample size is given as n = 35, which satisfies the condition of having a sufficiently large sample size (n >= 30).

Therefore, we can rely on the Central Limit Theorem, which implies that the sampling distribution of the test statistic (such as the sample mean) will be approximately normal, even if the population distribution is not.

The choice of a two-tailed test or the fact that the sample is random does not determine whether the population needs to be normally distributed.

It is the sample size that plays a key role in allowing us to make inferences about the population based on the Central Limit Theorem.

Hence, the correct answer is OB. No, because n >= 30. The assumption of normality is not required in this scenario due to the sufficiently large sample size.

The value of y(1) is found to be approximately 2.6742 based on the approximate values obtained using Euler's method.

First, we divide the interval [0, 1] into 10 subintervals (h = 0.1), resulting in 11 points including the initial point.

Using the Euler's method, we start with the initial condition y(0) = 1 and iterate the following formula for each step:

y_(i+1) = y_i + h * (t_i * y_i + t_i^2)

Calculating the values iteratively, we obtain a table of values for t and y as follows:

t | y

0.0 | 1.0000

0.1 | 1.1000

0.2 | 1.2110

0.3 | 1.3343

0.4 | 1.4708

0.5 | 1.6228

0.6 | 1.7920

0.7 | 1.9802

0.8 | 2.1892

0.9 | 2.4202

1.0 | 2.6742

Therefore, using Euler's method with a step size of h = 0.1, the approximate value of y(1) is 2.6742.

Euler's method is a numerical method used to approximate the solution of ordinary differential equations (ODEs). It uses small steps to approximate the derivative and iteratively updates the solution at each step. In this case, we applied Euler's method with a step size of h = 0.1 to approximate the solution y(1) for the given initial value problem. By calculating the values iteratively using the formula y_(i+1) = y_i + h * (t_i * y_i + t_i^2), we obtained a table of values that approximate the solution. The value of y(1) is found to be approximately 2.6742 based on the approximate values obtained using Euler's method.

The pool's hydrostatic force is 1,500 pounds at the shallow end, 4,500 pounds at the deep end, 1,500 pounds on each side from shallow to deep, and 0 pounds at the bottom.

(a) To compute the pressure the water exerts at that depth and multiply it by the shallow end's surface area, we must first measure the hydrostatic force on the shallow end. The equation P = gh, pressure is P, is the fluid's density, acceleration from gravity is g, the depth is h, determines the pressure that a fluid exerts at a given depth.

In this case, the depth of the shallow end is 3 ft. The weight density of water is given as 62.5 lb/ft³.

Plugging in these values, we have,

P = (62.5 lb/ft³) * (32.2 ft/s²) * (3 ft)

P = 1,500 lb/ft².

To find the hydrostatic force, we multiply this pressure by the surface area of the shallow end, which is the width times the length,

Hydrostatic force = 1,500 lb/ft² * (20 ft * 40 ft)

Hydrostatic force = 1,500 lb. Therefore, the hydrostatic force on the shallow end is 1,500 lb.

(b) Using the same method as in part (a), we find that the pressure exerted by the water at the depth of the deep end, which is 9 ft, is ,

P = (62.5 lb/ft³) * (32.2 ft/s²) * (9 ft)

P = 4,500 lb/ft².

Multiplying this pressure by the surface area of the deep end (20 ft * 40 ft), we get the hydrostatic force on the deep end,

Hydrostatic force = 4,500 lb/ft² * (20 ft * 40 ft)

Hydrostatic force = 4,500 lb.

Therefore, the hydrostatic force on the deep end is 4,500 lb.

(c) The depth of the side is varying linearly from 3 ft to 9 ft. Taking the average depth, we have (3 ft + 9 ft) / 2 = 6 ft.

Using the formula,

P = (62.5 lb/ft³) * (32.2 ft/s²) * (6 ft),

We find that the pressure is 3,000 lb/ft².

Multiplying this pressure by the surface area of the side (20 ft * 6 ft), we get the hydrostatic force,

Hydrostatic force = 3,000 lb/ft² * (20 ft * 6 ft)

Hydrostatic force = 1,500 lb.

(d) Since the bottom of the pool is horizontal, the depth remains constant throughout, which is 3 ft. Plugging this value into the formul,

P = (62.5 lb/ft³) * (32.2 ft/s²) * (3 ft),

p =  1,500 lb/ft², we find that the pressure is 1,500 lb/ft². However, since the bottom is horizontal, the surface area facing upward cancels out the surface area facing downward, resulting in a net force of 0 lb.

Therefore, the hydrostatic force on the bottom of the pool is 0 lb.

Step-by-step explanation:

(2x     )(x     )

We were told to use 7 and 12 to equal 84. Let's try 12 in the first bracket and 7 in the second:

(2x  12)(x   7): (2x)(7) and (12)(x) = 14x and 12x, which we cant make 17x from

Now let's try 7 in the first bracket and 12 in the second:

(2x   7)(x   12): (2x)(12) and (7)(x) = 24x and 7x, which we CAN use to make 17x if the 7x is negative, ie place a '+' before the twelve in the second bracket and a '-' before the seven in the first bracket.

(2x-7)(x+12)

Double check: (2x-7)(x+12)=2x(x+12)-7(x+12)=2x²+24x-7x-84=2x²+17x-84
