Answer:
D
Step-by-step explanation:
The formula we need to solve this is:
![d_1+d_2=2a](https://tex.z-dn.net/?f=d_1%2Bd_2%3D2a)
Where
is the distance from one focus to the vertex
is the second distance from another focus to same vertex
<u>Note:</u> Here, vertex point is the point on top. The common point from which the RED and BLUE line meets the 2 foci
is half the length of the major axis (which is 9 here since total major axis is given as 18)
<em>Now we can plug into the equation and solve:</em>

<em>D is the correct answer.</em>
If y what? I think you're missing part of the question...
Answer: Hello your question is poorly written attached below is the complete question
answer:
0.1515
Step-by-step explanation:
Number of bets = 200
mean number of losses = $0.2
Standard deviation = $2.74
<u>Determine P ( winning after 200 bets ) </u>
Average of 200 bets > 0. i.e. P( X > 0 )
considering normal distribution : μ = -0.2 , б = 2.74 , n = 200
applying Z - distribution
z = 0 - ( - 0.2 ) / ( 2.74 / √200 ) ≈ 1.03
∴ P ( z > 1.03 ) = 1 - P ( z < 1.03 )
= 1 - 0.8485 ( value gotten from z-table )
= 0.1515
Answer:
-5 =x
Step-by-step explanation:
f(x)=x+5
Set the function equal to zero
0 = x+5
Solve for x
-5 = x+5-5
-5 =x
The answer is going to 328.5 or 328.50 is the same thing
