Answer:
The answer is 48600, but I'm not entirely sure if it correct.
From what I know, if I were to see ¨y=7500(1.08)t¨, we could have to substitute the t with the number of years. Looking like this, ¨y=7500(1.08) x 6¨.
The reason I don know if my answer is correct or not since I don know if you have the t next to 1.08 to represent that or to simply multiply the property of it with 6 (the number of years).
So I tried...

Answer:
15% of 60 is 9
Step-by-step explanation:
15%= 3/20
3/20*60= 180/20
180/20= 9
15% of 60 is 9
Hope this helps!
Step-by-step explanation:
CONGRUENT TRIANGLES : Two triangles are said to be congruent if they have same sides and exactly same angles.
Now, any two triangles can be congruent by any of the following 3 properties:
1) SIDE SIDE SIDE (SSS) : Here three sides of triangle 1 is equal to the three sides of the triangle 2.
2) SIDE ANGLE SIDE (SAS) : Here two sides and including angle of triangle 1 is equal to the two sides and including angle of the triangle 2.
3) ANGLE SIDE ANGLE (ASA) : Here two angles and including side of triangle 1 is equal to two angles and including side of the triangle 2.
4) ANGLE ANGLE SIDE (AAS) : Here two angle and one side of triangle 1 is equal to the two angles and one side of the triangle 2.
Answer:
0.827
Step-by-step explanation:
Data provided in the question:
Probability of breakdown, p = once in 3 weeks i.e 
number of weeks n = 21
now,
mean, λ = np
= 
= 7
P(X > 4) = 1 - ( P(X ≤ 4))
using Poisson distribution
P(X = x) = 
Thus,
P(X = 0) = 
= 0.00091
P(X = 1) = 
= 0.00638
P(X = 2) = 
= 0.02234
P(X = 3) = 
= 0.05213
P(X = 4) = 
= 0.09123
Thus,
P(X ≤ 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)
= 0.00091 + 0.00638 + 0.02234 + 0.05213 + 0.09123
= 0.17299
Therefore,
P(X > 4) = 1 - 0.17299
= 0.827
