250-128 = 122J is reflected
Answer:
The correct option is;
c. 0.167
Explanation:
The parameters given are;
The mean, μ = 13.9 Gigagrams/year
The standard deviation, σ = 5.8 Gigagrams/year
The z-score formula is given as follows;
Where:
x = Observed score = 11.5 Gigagrams/year
We have;
From the z-score table relations/computation, the probability (p-value) = 0.6605
Where:
x = Observed score = 14 Gigagrams/year
We have;
From the z-score table relations/computation, the probability (p-value) = 0.4931
Therefore, the probability, 
, that the amount of carbon emissions from cars in Belgium for a randomly selected year are between 15.5 Gigagrams/year and 14 Gigagrams/year = The area under the normal curve bounded by the p-values for the two amounts of carbon emission
Which gives;
= 0.6605 - 0.4931 = 0.1674 ≈ 0.167
Therefore, the correct option is c. 0.167.
I don't know Im just Trying to get points somehow
Hello!! WOW, what a coincidence! I just took this lesson and quiz yesterday, so the answer is still fresh in my mind!
The answer to your question is
D) Blowing sand can wear away a rock's surface and break it into smaller pieces
When wind blows, sure it can pick up dry soil and sand and relocate it, but that doesn't cause the weathering in rocks.
Wind doesn't create new landforms either, that comes from plate tectonic movements and other things.
I just eliminated B and C with the two sentences above, I really don't know how to eliminate A, just common sense i guess.
Please give me brainliest if I was correct and helpful!
Otherwise, please comment and let me know how I can fix my answer!
Thank you, it was fun, have a nice week!
Answer: 7.29 g of 
will be produced from the given masses of both reactants.
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of 
require = 8 moles of 
Thus 0.0267 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 mole of give = 8 moles of
Thus 0.0267 moles of give = of
Mass of 
Thus 7.29 g of will be produced from the given masses of both reactants.
