Answer:
A voice type is a singing voice identified as having certain qualities or characteristics of vocal range, vocal weight, tessitura, vocal timbre, and vocal transition points, such as breaks and lifts within the voice.The purpose of the key signature is to minimize the number of such accidentals required to notate the music. The sequence of sharps or flats in key signatures is generally rigid in modern music notation. ... In a score containing more than one instrument, all the instruments are usually written with the same key signature.Bass, Baritone, Tenor, Alto, Mezzo-Soprano, and Soprano. If you've been part of a choir before, you're probably pretty familiar with these ranges.Image result for How do sharps or flats work on a scale?
A sharp symbol on a line or space in the key signature raises the notes on that line or space one semitone above the natural, and a flat lowers such notes one semitone. ... Each major and minor key has an associated key signature that sharpens or flattens the notes which are used in its scales
This should be it I think
Option B: A three-dimensional solid made from a pile of similar two-dimensional
circles that grow smaller as the solid gets taller until it reaches a
point at the vertex
The A is a cylinder, the D es pyramid, and I cannot figure out what the C is.
2(n-9) = 3(n + 5)
2n - 18 = 3n + 15
2n - 3n = 15 + 18
-n = 33
n = -33
For example:
Find: (3-i)+(2+3i) by graphing
Step 1: Graph 3-i and 2+3i on the complex plane. Connect each of these numbers to the origin with a line segment.
D=event that chip selected is defective
d=event that chip selected is NOT defective
Four possible scenarios for the first two selections:
P(DDD)=15/100*14/99*13/98=13/4620
P(DdD)=15/100*85/99*14/98=17/924
P(dDD)=85/100*15/99*14/99=17/924
P(ddD)=85/100*84/99*15/98=17/154
Probability of third selection being defective is the sum of all cases,
P(XXD)=P(DDD)+P(DdD)+P(dDD)+P(ddD)
=3/20
