100 + 75
25(4 + 3)
49 + 28
7(7 + 4)
32 + 24
8(4 + 3)
Cosine = adjacent / hypotenuse so that is the trig ration we use here:-
cos M = 32/41 = 0.78049
m < M = 38.69 degrees to nearest hundredth
Answer:
a) 142506
b) 61776
c) 0.4333
Step-by-step explanation:
Given
Three microchips in a production run of thirty are defective
The probability of having a defective microchips is 3/30 = 0.1
Probability of having a good microchip is 0.9
a) Possible ways of selecting five sample =
30C5
30*29*28*27*26*25!/25! *5! = 17100720/120 = 142506
b) With one defective microchip
Total sample – sample without any defective microchip
142506 – 37C5
142506 – 80730
61776
c) Probability = 61776/142506 = 0.4333
Answer:
Different Figure Answers
Step-by-step explanation:
Point
A point is the most fundamental object in geometry. It is represented by a dot and named by a capital letter. A point represents position only; it has zero sizes (that is, zero-length, zero-width, and zero height). Figure 1 illustrates point C, point M, and point Q.
Figure 1
Three points.
Line
A line (straight line) can be thought of as a connected set of infinitely many points. It extends infinitely far in two opposite directions. A line has infinite length, zero-width, and zero height. Any two points on the line name it. The symbol ↔ written on top of two letters is used to denote that line. A line may also be named by one small letter (Figure 2).
Figure 2 Two lines.
Collinear points
Points that lie on the same line are called collinear points. If there is no line on which all of the points lie, then they are noncollinear points. In Figure 3, points M, A, and N are collinear, and points T, I, and C are noncollinear.
Figure 3 Three collinear points and three noncollinear points.
Plane
A plane may be considered as an infinite set of points forming a connected flat surface extending infinitely far in all directions. A plane has infinite length, infinite width, and zero height (or thickness). It is usually represented in drawings by a four‐sided figure. A single capital letter is used to denote a plane. The word plane is written with the letter so as not to be confused with a point (Figure 4 ).
Figure 4 Two planes.
