29. 7y^(4)-8x^(4)y^(4)-6x^(4)y^(3)-4xy^(3)
30. 7y^(3)-9x^(4)y^(4)-11x^(4)y^(3)
Step-by-step explanation:
just trust me lol
Answer:
46 ≤ n ≤ 60 ( C )
Step-by-step explanation:
using the given null hypothesis to check if the samples differ from originally values
given that: frequency ( f ) ≥ 5
N = 600
hence : n * 0.11 ≥ 5
therefore : n ≥ 45.45
next : also n / N ≤ 0. 10
therefore: n ≤ 0.1 * 600
therefore all possible sizes will lie between
46≤n≤60
If the area is 168& the length is 2 feet more so length is 14& width is 12 (14*12= 168), the rug is 8feet in total less from all sides so it gives an area on 160. To come out with length& width knowing the length should be less than 14, so it could be either (10*16, 8*20)
Answer:
9.50$
Step-by-step explanation:
First, multiply 20 by the given fractions
20*1/8=2.5
20*2/5=8
Add the two together to get the total amount of money Jeff spent, 10.5, then subtract 10.5 from 20 to get the total amount he has left, 9.5
