Answer:
Length of the segment QS = 11.76 cm
Step-by-step explanation:
We are given with right angle triangle QRS
Angle S is 80 degree and RS = 2 cm
We need to find out QS
RS is adjacent to angle S, so we use cos formula
Plug in the angle and RS
Given cos(80) = 0.17
Multiply by QS on both sides
0.17 * QS = 2
Divide by 0.17 on both sides
QS= 11.76470588
Length of the segment QS = 11.76 cm
Answer:
Step-by-step explanation:
7x-11=4x+4(being vertically opposite angles)
7x-4x=4+11
3x=15
x=15/3
x=5
angle 2+angle1=180 degree(being straight line)
7x-11+angle 1=180
7*5-11+angle 1=180
35-11+angle1=180
24+angle 1=180
angle 1=180-24
angle 1=156 degree
Answer:
P(X = 0) = 0.25
P(X = 1) = 0.75
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The probability distribution of X.
3 red balls out of 4, one picked, so we can have either 0 red balls or 1 red ball. The probability disitribution is the probability of each outcome.
