Answer:
x=5
y=2
Step-by-step explanation:
5x + 3y= 31
-6x - 3y = -36 (multiple by -3)
-x=-5
x=5
2(5)+y=12 or 25 + 3y= 31
10+y=12 3y=6
y=2 y=2
Answer:
a)ΔFHA is similar to ΔZIA by hypotenuse side test.
reason:- angle H and angle I are of 90 degrees.
b) FH/ ZI = HA/ IA = FA/ ZA
angle F = angle Z, angle H = angle I , angle angle A = angle A
The scale factor is 3/2......( HA/IA = 12/8 = 3/2)
c) IZ = 3.3 ....( FH/ IZ = 3/2, 5/ IZ = 3/2, IZ = 10/3 = 3.33)
Answer:
The probability of hitting an odd number three times is 3.375 times more than the probability of hitting an even number three times..
Step-by-step explanation:
Probability of hitting an odd number = 3/5
Probability of hitting an odd number = 2/5
Probability of hitting an odd number three times = (3/5)^3
Probability of hitting an odd number three times = (2/5)^3
Now divide (3/5)^3 by (2/5)^3 we get:
(3/5)^3 / (2/5)^3
(3)^3/(2)^3
27/8 = 3.375
The probability of hitting an odd number three times is 3.375 times more than the probability of hitting an even number three times..
