Answer:
x = ±6 or 
you just take the square root of 36 to find one x
Answer:
the probability the person's reaction time will be between 0.9 and 1.1 seconds is 0.0378
Step-by-step explanation:
Given the data in the question;
the cumulative distribution function F(x) =
;
probability the person's reaction time will be between 0.9 and 1.1 seconds
P( 0.9 < x < 1.1 ) = P( x ≤ 1.1 ) - P( x ≤ 0.9 )
P( 0.9 < x < 1.1 ) = F(1.1) - F(0.9)
= [
] - [
]
we substitute
= [
] - [
]
= [
] - [
]
= [
] - [
]
= [ 1 - 0.1079796998 ] - [ 1 - 0.1457938 ]
= 0.8920203 - 0.8542062
= 0.0378
Therefore, the probability the person's reaction time will be between 0.9 and 1.1 seconds is 0.0378
Given:
Four series of angles are given.
To Find:
Identify the series with the correct order from greatest to least.
Solution:
the correct order from greatest to least is what is shown in the fourth option, i.e.,

Calculation:
Now, we use the fact that

to calculate the values of

So, we have

Looking at the above values, we see that the correct order from greatest to least is what is shown in the fourth option, i.e.,
