Answer: They are parallel so there is no solution.
Step-by-step explanation:
Brayden- y=5x-1 or y-5x= -1
Howard- y=5x+1 or y-5x= 1
Vincent- y=4x+5 or y-4x= 5
In summary, they are all parallel so there is no solution.
Answer:
3 option is correct
Step-by-step explanation:
because all the domains and ranges calculation matches in eqn 3
115% is the same as 1.15
some number = x
115% of some number is 120
1.15 of x is 120
1.15 * x = 120
x = 104.3478
<span>x ≈ 104.3</span>
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
