So first you factor it out:
8c - 72 = 12c - 72 - 4c
Then you isolate the c's:
-72 +72 = 12c - 4c -8c
Then you add both sides:
0 = 0c
C is equal to 0
Answer:
D. The given expression is sixty - eight less than (1271 ÷ 1/5)
Step-by-step explanation:
(1271 ÷ 1/5) - 68
Expression should be:
Sixty - eight less than (1271 ÷ 1/5)
Answer: 161, 142, 123, 104, 85,
Step-by-step explanation: 180-19=161-29=142 and so on
That would be the surface area of a circle with a radius of r.
60=4πr^2
r^2=15/π
r=√(15/p) and if we use 3.14 as an approximation of π
r=√(15/3.14)
r≈2.19 units to nearest hundredth of a unit
Answer: 0.2872
Step-by-step explanation:
Given : In a sample of 1000 randomly selected consumers who had opportunities to send in a rebate claim form after purchasing a product, 260 of these people said they never did so.
i.e. n= 1000 and x= 260
⇒ Sample proportion :
z-value for 95% confidence interval :
Now, an upper confidence bound at the 95% confidence level for the true proportion of such consumers who never apply for a rebate. :-
∴ An upper confidence bound at the 95% confidence level for the true proportion of such consumers who never apply for a rebate : 0.2872
