Answer:
B) μD = 0.60 ± 0.10(1.397)
Step-by-step explanation:
The confidence interval is given by:
Where
MD=60
n=9
df=n-1=8
Then the confidence interval is
μD=0.60±1.397*(0.3/√9)
μD=0.60±0.10*(1.397)

Step-by-step explanation:
12(5x−4.5)=36
(12)(5x)+(12)(−4.5)=36(Distribute)
60x+−54=36
60x−54=36
Step 2: Add 54 to both sides.
60x−54+54=36+54
60x=90
Step 3: Divide both sides by 60.
60x

You subtract two and then multiply by -7and you get a<63
Answer:
The volume is 192
Step-by-step explanation:
Multiply the bottom numbers which are 2, 2, 6, 4, and 2.
4³ ⋅ (100 ÷25) − 5^0
[parenthesis goes first, then exponents]
[any coefficient with zero exponent is equal to 1]
64 · 4 - 1
[multiplication, then subtraction]
256 - 1
<u>255</u>
