Answer:
There is a common ratio of 1/4.
The next 3 numbers are -80, -20 , -5.
Step-by-step explanation:
The next term is found by multiplying by 1/4. ( -5120 / 20480 = 1/4).
So the next 3 terms are -320 * 1/4 = -80,
-80 * 1/4 = -20 and the last is -5.
Answer: 70 - 40 = 30
Step-by-step explanation:
Undo what has been done to the variable. That means to do the opposite done to the variable.
5x-4=-19
+4=+4
5x=-15
5 is being multiplied to the variable so you divide it from both sides.
x=-3
Given that μ=0, and σ=1, P(z>c)=0.1093
thus
P(z<c)=1-0.1093=0.8907
hence the value of c will be:
z-score=(c-μ)/σ
thus
1.23=(c-0)/1
c=1.23
I believe the original price of the television was 580.56 because 492*18%=88.56 so 492+88.56=580.56 hope this helps
