Answer:
4 cm
Step-by-step explanation:
The area of the triangle is half the area of the rectangle. The base of the triangle is the diameter of the circle, 14 cm. So the height is found from ...
A = 1/2bh
(56 cm²)/2 = 1/2(14 cm)h
h = (28 cm²)/(7 cm) = 4 cm
The height of triangle ADC is 4 cm.
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.
how is the volume of a solution used in calculating concentration?
Similar triangles have corresponding sides with proportional lengths.
AB/BC = DE/EF
5/9 = 7.5/EF
5(EF) = 9 * 7.5
5(EF) = 67.5
EF = 13.5
15.5 is rounded to the nearest tenth. If you're looking for which number is closest to a whole number then it would be 16 since 5 is always rounded up. Hope this helped :)
