Answer:
Explanation:
3. Find LCM of (30, 9):
30 = 2 x 3 x 5
9 = 3 x 3
Thus : LCM(30, 9) = 2 x 3 x 3 x 5 = 90
Therefore, in 90 days he will has both activities again.
4. Determine whether its possible to construct a triangle with the given length.
a.
8 + 9 > 11 (true)
8 + 11 > 9 (true)
9 + 11 > 8 (true)
Thus 8,9 and 11 can be construct as a triangle.
b.
4 + 5.1 > 12.5 (false)
4 + 12.5 > 5 (true)
12.5 + 5 > 4 (true)
Thus, 4, 5.1 and 12.5 cannot be constructed as a triangle.
Answer:
Length: 10
Surface Area: 20
Step-by-step explanation:
Length:
2*12=24
240/24=10
Surface Area:
2*10=20
No they are not functions

Answer:
6.76
Step-by-step explanation:
Let us create hypothesies as

(right tailed test for claiming most adults would erase)
Sample proportion p = 0.64
n = sample size = 582
Std error of proportion= 
P difference = 0.14
Test statistic = p difference/std error
= 6.755
=6.76
