Answer:
The probability that she rolls a number greater that 4 or a 2 = or 50%
Step-by-step explanation:
Given:
A six sided number cube is rolled labelled from 1 to 6.
To find the probability that she rolls a number that is greater than 4 or a 2.
Solution:
The possible outcomes of rolling a six-sided cube are:
{1,2,3,4,5,6}
Event A:
The favorable outcomes greater than 4 are:
{5,6}
Probability of event A to occur =
Event B:
The favorable outcome is a 2
{2}
Probability of event B to occur =
We find that the two events are mutually exclusive as they have no common outcomes.
Thus, the probability that event A or B occurs ( P(AUB) ) can be given as:
⇒
Since denominators same, so we add the numerators.
⇒
Reducing it to simpler fraction:
⇒ (Answer)
Thus, the probability that she rolls a number greater that 4 or a 2 = or 50%
Answer:
Option A The linear model on tar content accounts for 92.4% of the variability in nicotine content.
Step-by-step explanation:
R-square also known as coefficient of determination measures the variability in dependent variable explained by the linear relationship with independent variable.
The given scenario demonstrates that nicotine content is a dependent variable while tar content is an independent variable. So, the given R-square value 92.4% describes that 92.4% of variability in nicotine content is explained by the linear relationship with tar content. We can also write this as "The linear model on tar content accounts for 92.4% of the variability in nicotine content".
Answer:
The angle would be acute
Step-by-step explanation:
We need the numbers but usually the first quart is before the median which is the number in middle, hope that made sense
342 = a²
switch sides:
for x² = f(a) the solutions are x = √ f(a) and - √ f(a)
therefore:
√ 342 = 18
-√ 342 = - 18
a = 18 and a = - 18
hope this helps!
