The chances of getting 6 on a six-sided die are 1/6, therefore the first one is correct.
Answer:
<u>f(-8) = 64</u>
Step-by-step explanation:
<u>Given conditions</u> :
<h3>f(x) = { x², if x < 0}</h3><h3>or </h3><h3>f(x) = {∛x, if x > 0}</h3>
<u>We have x = -8</u>
⇒ It follows x < 0
Therefore, substituting x = -8 in the function :
- f(-8) = (-8)²
- <u>f(-8) = 64</u>
Answer:
IQR = 20
Step-by-step explanation:
Quartile 1 = 25
Quartile 3 = 45
To find the interquartile range, take Q3 from Q1
45 - 25 = 20 .
Answer:
34.5% probability that the jury returns a guilty verdict
Step-by-step explanation:
We have these following probabilities:
The defense attorneys have a 70% chance of convincing the jury that the police either contaminated or planted some of the key evidence.
In this case, there is a 15% probability that the jury will return a guilty verdict.
There is also a 100 - 70 = 30% of not convincing the jury that the police either contaminated or planted some of the key evidence.
In this case, 80% probability of the jury returning a guilty verdict.
What is the probability that the jury returns a guilty verdict?
15% of 70% and 80% of 30%. So
![p = 0.15*0.7 + 0.8*0.3 = 0.345](https://tex.z-dn.net/?f=p%20%3D%200.15%2A0.7%20%2B%200.8%2A0.3%20%3D%200.345)
34.5% probability that the jury returns a guilty verdict
