Answer:
Option (A) 0.40951
Step-by-step explanation:
We are given the following information in the question:
P(target) = 0.90
Let the random variable X represent the number of times he hits ring of the target with a shot of the arrow.
The probability distribution of X is
x: 0 1 2 3 4 5
P(x): 0.00001 0.00045 0.00810 0.07290 0.32805 0.59049
The mean of discrete probability distribution is given by:
Now, we have to evaluate
Option (A) 0.40951 t is the probability that the number of times Luke will hit the inner ring of the target out of the 5 attempts is less than the mean of X.
<h3>I'll teach you how to solve 4m^2 - 10= -6</h3>
-----------------------------------------------------
Add 10 to both sides:
4m^2-10+10= -6+10
Simplify:
4m^2= 4
Divide both sides by 4:
4m^2/4= 4/4
Simplify:
m^2= 1
For x^2 = f(a) the solutions are x = 
- :
m= 
, m= -
Simplify:
m = 1, m = -1
Your Answer Is m = 1, m = -1

Hey there :)
We know the formula for simple interest is
I = prt
{ The picture includes what each stands for }
Lehena:Initial amount = $100
Interest rate = 2.5% =
Time = 3 years
I = ( 100 )( 0.025 )( 3 )
= 7.5$
Total = $100 + $7.5 =
$107.5Marty:Initial amount = $100
Interest rate = 2% =
Time = 3 years
I = ( 100 )( 0.02 )( 3 )
= $6
Total = $100 + $6 =
$106How much more than Marty did Lehena receive?= Total Amount of Lehena - Total Amount of Marty
= 107.5 - 106
= $1.5Your answer will be option
B) $1.50
Answer:
9
Step-by-step explanation:
The absolute value of -3 is |-3|, which in turn is 3. Thus we have
3(3), or 9. The fourth answer choice is the correct one.
