I got x= -7. hope that helps you out!
Let (a) be the first cat
let (b) be the second cat
a +b=11kg-----(1)
a=b+1500g⇒(1.5 kg)-------(2)
so now u have a system of two unknowns
a=11-b
substitute a in (2)
11-b=b+1.5
11-1.5=2b
2b=9.5
b=9.5/2=4.75
subs. b in (1)
a+b=11
a+4.75=11
a=11-4.75=6.25
so cat (a) is 6.25 kg
and (b) is 4.75 kg
hope I helped
The two triangles on the side are 18 in^2 and the square in the middle is 36 in^2. So in total, it has an area of 72 in^2
Answer:
(1) 0.4207
(2) 0.7799
Step-by-step explanation:
Given,
Mean value,

Standard deviation,

(1) P(X ≥ 17.5) = 1 - P( X ≤ 17.5)




( By using z-score table )
= 0.4207
(2) P(14 ≤ X ≤ 18) = P(X ≤ 18) - P(X ≤ 14)



= 0.9918 - 0.2119
= 0.7799
The first one pretty sure :))))
