Suppose x has a distribution with πœ‡ = 70 and 𝜎 = 11. (a) If random samples of size n = 16 are selected, can we say anything about the x distribution of sample means? No, the sample size is too small.Yes, the x distribution is normal with mean πœ‡ x = 70 and 𝜎 x = 0.7. Yes, the x distribution is normal with mean πœ‡ x = 70 and 𝜎 x = 11.Yes, the x distribution is normal with mean πœ‡ x = 70 and 𝜎 x = 2.75. (b) If the original x distribution is normal, can we say anything about the x distribution of random samples of size 16? Yes, the x distribution is normal with mean πœ‡ x = 70 and 𝜎 x = 11.No, the sample size is too small. Yes, the x distribution is normal with mean πœ‡ x = 70 and 𝜎 x = 0.7.Yes, the x distribution is normal with mean πœ‡ x = 70 and 𝜎 x = 2.75. Find P(66 ≀ x ≀ 71). (Round your answer to four decimal places.)

1 point The flatter the demand curve through a given point, the smaller the price elasticity of demand at that point (in absolute value). greater the absolute value of the change in total revenue when there is a movement from that point upward and to the left along the demand curve. greater the price elasticity of demand at that point (in absolute value). closer the price elasticity of demand will be to the slope of the curve. 1 point A manufacturer produces 1,000 units, regardless of the market price. For this firm, the price elasticity of supply is

ii. The four spotlights in part (b)(i) have been replaced by four white light emitting diode (LED) spotlights. They provide the same amount of light as the halogen spotlights and are used for the same 2400 hours per year. Assuming that the average efficacy of the halogen spotlights is 17 lumens per watt and that of the LED spotlights is 70 lumens per watt, calculate the new annual electricity consumption.

(II) The 9.0-kg mass in Fig. is held just barely in contact with a spring for which $k = 430 \text{ N/m}$. When that mass is released, it falls, compressing the spring and pulling the 3.0-kg mass up. How far does the 9.0-kg mass fall before momentarily coming to rest? Ignore friction in the pulley.

Project Activity 26.3. Now we look for P...= [b'][b] [b3]]. Assume that the plane p in B+B which the planet's orbit lies has equation z = ax + by. a) Explain why b = cos(b1) + sin(b2). (b) The x' axis is the intersection of the plane z = ax + by with the plane z = 0, so the equation of the axis in terms of x and y is x + by = 0. Now we determine the coordinates of b in terms of the basis B. i. Explain why the vector [b - a 0] lies on the x' axis. We take this vector to point in the positive x' direction. This gives us another representation of b' - namely that ii. Explain why a vector in the plane z = ax + by orthogonal to b' is [a b a^2 + b^2]. iii. From the previous part we have b^2 = Let G (0, 0) be the terminal point of the projection of b^2 onto the xy plane. Show that OG is orthogonal to by. iv. Let θ be the angle between the plane p and the y plane as illustrated at right in Figure 26.3. Explain why ||OG|| = cos(θ). Then explain why b = [-cos(θ) sin(θ) cos(θ) cos(θ) sin(θ)]^T. (Hint: Use the trigonometric identities cos(A + B) = -sin(A) and sin(A + B) = cos(A).)
