Answer:
a
Step-by-step explanation:
-2 over 3 is it cuz -4 over 6 simplifies to that and all the others do too
A equals 4 and
B equals 1
Answer:
So x=2.32956156226
Step-by-step explanation:
First subtract 1 on both sides
2^3x=127
Now you can rewrite this as
(2^3)^x
As it still equals the same thing
Now 2^3 is 8
So the equation is now
8^x=127
So we use log formula
log8 127=x
So how many times do we have to multiply 8 by itself to get 127?
The answer is: 2.32956156226
Hope this helps!
Say you're making a recipe that needs 2 1/2 cups of water. But you want to make two servings, so you need to know what 2 1/2 + 2 1/2 equals. Or maybe you need a half cup of milk but you don't have enough. You need to know how much left you need so you can buy or borrow the right amount.
Answer: d) $369.31 to $380.69
Step-by-step explanation:
Given;
Mean price x= $375
Standard deviation r= $20
Number of retail stores n = 50
Confidence interval of 95%
Z*(95%) = 1.96
Confidence interval = x+/-Z*(r/√n)
= $375+/- 1.96(20/√50)
= $375+/- 5.69
Confidence interval = ($369.31 to $380.79)
