Answer:
0.003
Step-by-step explanation:
6-3 =3 and 4-4 = is 0 and 8-8= 0 so the answer is 0.003
2x - 2 < -12 or 2x + 3 > 7
2x < -12 + 2 or 2x > 7 - 3
2x < -10 or 2x > 4
x < -5 or x > 2
Answer:
You would make a dotted vertical line running through -6 on the horizontal or x axis. The shading would go to the left side of the line since x is less than -6 and the line is dotted because it is only less than and not equal to.
Step-by-step explanation:
See image
2x^2 -5x -3 = 0
D = 25 +24 = 49
x_1,2 = (5+/- sqrt49)/4 = (5+/-7)/4 = -2/4 = -1/2 and 12/4 = 3
x_1,2 = -1/2 and 3

Answer: 0.6274
Step-by-step explanation:
Given: The proportion of patients experience injection-site reactions with the current needle : p=0.11
Sample size : n= 4
Let x be a binomial random variable that represents the people get an injection-site reaction.
Binomial probability formula:
The required probability : P(x=0)
Hence, the probability that none of the 4 people get an injection-site reaction = 0.6274
