Answer:
About $118.70
Step-by-step explanation:
139 x .2 = 27.8
139 - 27.8 = 111.2
111.2 x .0675 = 7.5
111.2 + 7.5 = 118.7
118.7 = $118.70
Answer:
95% Confidence interval: (0.375,0.377)
Step-by-step explanation:
We are given the following in the question:
Sample mean,
= 0.376 cc/cubic meter
Sample size, n = 15
Alpha, α = 0.05
Sample standard deviation, s = 0.0012
Degree of freedom =

95% Confidence interval:
Putting the values, we get,
(0.375,0.377) is the required 95% confidence interval for the population mean potassium chloride concentration.
Answer:
It is the Last answer D
Step-by-step explanation:
because 15/2 is equal to 7 1/2
the square room of 64 is 8
and 8.1444444 is less than 8 1/7
Ok, so it seems
erm
ok, even and odd
it is an odd one because the power is odd (3rd degree)
so then the ends go in different directions
and since leading coefient (5 in the 5x^3) is positive, it goes from bottom left to top right
so
A is false
B is false
C and D are true
answer is C and D
4(-6x – 3) + 24x = -72x + 132
Step 1 -24x – 12 + 24x = -72x + 132 Distribute Property of Equality
Step 2: –12 = -72x + 132 equivalent
Step 3: -144 = -72x Subtraction Property of equality
Step 4: 2 = x Equivalent / Division property of equality
