salantis [7]

X = width
2x-3 = length

 $x(2x-3) = 65\\
2x^2 - 3x - 65 = 0 \\ D=b^2-4ac=(-3)^2-4*2*(-65)=529\\
x_{1,2}= \frac{-bб \sqrt{D} }{2a}= \frac{3б 23}{4} \\ x_1=-5 \ \ \O \\ x_2=6.5 \ \$

width = 6.5 m
length = 2x-3 = 2*6.5 - 3 = 10 m

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

Determine P ( winning after 200 bets )

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
