Answer:
Gah! Inverses!
Step-by-step explanation:
This is a pretty simple concept, just switch the x and f(x) values!
If you don't understand, look at how I solve it!
Switching the positions of the x and f(x) values...
Note: That f(x)^-1 is the proper notation for inverse functions.
There you go!
Hope this helps, and don't procrastinate!
Answer:
- a. 552 square inches
- b. 835.7 square inches
- c. 1256.6 square inches
- d. 4584 square inches
- e. 432 cubic inches
- f. 1847.3 cubic inches
- g. 4188.8 cubic inches
- h. 9179.3 cubic inches
Step-by-step explanation:
a-c. The area formulas for these figures are ...
rectangular prism: A = 2(lw +h(l+w))
cylinder: A = 2πr(r +h)
sphere: A = 4πr^2
d. The total will be the sum of products: area of each pillow times the number of that type
__
e-g. The volume formulas for these figures are ...
rectangular prism: V = lwh
cylinder: V = πr^2h
sphere: V = (4π/3)r^3
h. As with area, the total volume is the sum of products: volume of each pillow times the number of that type.
The 90% confidence interval is between R96.94 and R105.06
The confidence (C) = 90% = 0.9, Mean (μ) = 101, standard deviation (σ) = 39, sample size (n) = 250
α = 1 - C = 1 - 0.9 = 0.1
α/2 = 0.1 / 2 = 0.05
The z score of α/2 corresponds with the z score of 0.45 (0.5 - 0.05) which is equal to 1.645
The margin of error (E) is given by:
The confidence interval = μ ± E = 101 ± 4.06 = (96.94, 105.06)
Therefore the 90% confidence interval is between R96.94 and R105.06
