Answer:
95% confidence interval: (0.325 ,0.383)
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 231
Sample mean = 0.354 ppm
Sample standard deviation = 0.231 ppm
95% confidence interval:
Putting the values, we get,
Answer:
<em>2(15+8)</em>
Step-by-step explanation:
Given the expression 30+16
We are to use GCF to rewrite the sum as a product.
Get the factor of each value first as shown;
30 = 2 * 15
16 = 2 * 8
substitute the factors back into the expression:
30+16 = (2*15)+(2*8)
Since 2 is common to both terms, then:
30+16 = 2(15+8)
<em></em>
<em>Hence the required sum of product of the terms is 2(15+8)</em>
They all end up being 1
100% = 1
4/4 = 1
1.000 = 1
All you need to do is divide -1/2 onto the other side.
-1/2x<-12
-12/ (-1/2)= 6 (a negative and a negative equals a positive)
Also, since you are dividing a negative, you flip the sign.
x>6

hope this helps :D
Step by Step: To find the molecular mass of SO2, you are going to want to search out the mass of SO2. The mass of sulfur is 32AMU, and also the mass of oxygen is 16AMU, then times two thanks to the subscript, so 32. Add those up, and 32+32=64AMU, which is your mass for the entire.
