A machine is designed to fill 16-ounce bottes of shampoo. When the machine is working properly, the amount poured into the bottl

es follows a Normal distribution with mean 16.05 ounces and standard deviation 0.1 ounce. Assume the machine is working properly. If 4 bottles are randomly selected and the number of ounces in each bottle is measured, then there is a 95% probability the sample mean will fall in which of the following intervals?(a) 16.05 to 16.15 ounces (b) 16.00 to 16.10 ounces (c) 15.95 to 16.15 ounces (d) 15.90 to 16.20 ounces (e) 15.85 to 16.25 ounces

Answer:

(D) 15.90 to 16.20 ounces

Step-by-step explanation:

Confidence Interval = mean + or - (t×sd)/√n

Mean = 16.05 ounces, sd = 0.1 ounce, n = 4, degree of freedom = n - 1 = 4 - 1 = 3, t = 3.182

Lower limit = 16.05 - (3.182×0.1)/√4 = 16.05 - 0.15 = 15.90 ounces

Upper limit = 16.05 + (3.182×0.1)/√4 = 16.05 + 0.15 = 16.20 ounces

The sample mean will fall from 15.90 to 16.20 ounces

263.27 m^2

rectangle : 15 x 10 = 150 m^2
the half circle at the top has a diameter of 6m. therefore, it’s radius is 3m. if it is cut in half, the part removed from the triangle height is 3m. therefore, the height of the triangle is 35 -15 = 20; 20 - 3 = 17. the height of the triangle is 17. the triangle area formula is a = 1/2(bh).
a = 1/2 (10)(17)
a = 1/2 (170)
a = 85 m^2
the circle would be a = πr^2 but divided by 2 bc it’s a half circle
a = π(3)^2
a = π9
a = 28.27 m^2
150 + 85 + 28.27 = 263.27 m^2

Which description does NOT guarantee that a trapezoid is isosceles?
babunello [35]

A trapezoid is isosceles if and only if

(1) The base angles are congruent

(2) The diagonals are congruent

(3) The opposite angles are supplementary

So the description does not guarantee that a trapezoid is isoceles for "Congruent bases".
