Answer:
a. SE = 0.403 mol
Step-by-step explanation:
The standard error of the mean, is the standard deviation of means of means.
It is calculated using,
We have the standard deviation to be
and the sample size is n=146.
We substitute the values to get:
We approximate to three decimal places to get:
9514 1404 393
Answer:
487.2 in²
Step-by-step explanation:
The area of the semicircle is ...
A = (1/2)πr² . . . . . where r is half the diameter
A = (1/2)π(9 in)² = 40.5π in² ≈ 127.2 in²
The area of the rectangle is ...
A = bh
A = (18 in)(20 in) = 360 in²
Then the total area is ...
total area = semicircle area + rectangle area
= 127.2 in² +360 in² = 487.2 in² . . . . . area of the wood base
Answer:
Step-by-step explanation:
Given
<u>Functions:</u>
- S(t) = –0.122t³ + 3.49t² – 14.6t + 136
- H(t) = –0.115t³ + 3.71t² – 20.6t + 124
<u>Finding the difference between S(5) and H(5)</u>
- S(5) - H(5) =
- –0.122t³ + 3.49t² – 14.6t + 136 - (–0.115t³ + 3.71t² – 20.6t + 124) =
- (-0.122 + 0.115)*5³ + (3.49 -3.7)*5² - (14.6 -20.6)*5 + 136 - 124 = 35.875
Answer is 35.875 grams

A).
B).
C).
D).
For matching with givens graph:
Simplifying...
A).
Divide 2 on both sides
B).
Add (-6) on both side.
C).
Add (4) on both side.
D).
Multiple (-1) on both side
Note : Change of inequality sign due to multipication of negative number
Add (-5) on both side.
Here, Answer is given in form of 4 figure labelled with inequality
Three because the smaller the a value is, the narrower the graph.
