x = 27 + 3 √ 129/ 4 , 27 − 3 √ 129/ 4
Note: the entire equation above is divided by 4, not just the last term.
x ≈ 15.26836251, − 1.76836251
That's all I got. Hopefully, this helps. You'll still need to solve for y and z, but its pretty hard :)
Answer:
65
Step-by-step explanation:
TAB is an isosceles triangle by the point to tangent theorem theorem.
BAT and BAT are congruent because of the isosceles triangle definition.
CAT and ABT are right angles by the tangent theorem.
Thus, CAB and CBA are both 90 - 65 = 25.
ACB is 130 because triangles' angles add up to 180.
APB is one half of ACB by the inscribed angles theorem.
Answer:
6
Step-by-step explanation:
Answer:
95.4% of family vehicles is between 1 and 3 years old.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 2
Standard Deviation, σ = 6 months = 0.5 year
We are given that the distribution of age of cars is a bell shaped distribution that is a normal distribution.
Formula:

P(family vehicles is between 1 and 3 years old)

95.4% of family vehicles is between 1 and 3 years old.
Area=height times base (for some prisms including cylinders)
vcylinder=hpir²
h=height
therefor pir²=base area
vcylinder=height times aeraofbase
given
h=9
v=324pi
324pi=9(basearea)
divide both sides by 9
36pi=areabase
the area of the base is 36pi square cm (put 36 in the blank since the pi is already there)
