You have to do length of the base x width of the base x height of pyramid
20m/s
Speed=distance/time
Speed = 100/5 = 20
Answer = 20m/s
You roll a die with the sample space S = {1, 2, 3, 4, 5, 6}. You define A as {1 ,4, 6}, B as {1, 3, 4, 5, 6}, C as {1, 5}, and D
Lilit [14]
Answer:
Step-by-step explanation:
Recall that two events A,B are called mutually exclusive if and only if 
(their intersection is empty). They are exhaustive if they are mutually exclusive and their union is the sample space.
Based on this
a) Note that 
, so they are not mutually exclusive nor exhaustive.
b) 
so they are not mutually exclusive nor exhaustive.
c) 
, so they are mutually exclusive. Note that 
. Then they are exhaustive.
d) 
, so they are not mutually exclusive nor exhaustive.
2pi radians=360 degrees
rato and proprtion
xrad/(2pi)=ydeg/360
xrad/2pi=82/360
times both sides by 2pi
xrad=164pi/360
xrad=41pi/90
aprox pi=3.141592
xrad=1.431
round
xrad=1.43 radians
1.43 radians=82 degrees
Answer: 27.688
Step-by-step explanation:
The critical chi-square value 
depends on significance level (
) and degrees of freedom (df) .
Given significance level: () = 1% = 0.01
Degrees of freedom (df)= 13
From the chi-square table, the critical chi-square value for df = 13 and 
is 
Hence, the required critical value = 27.688
