Answer:
Negative 8 over 5 comma negative 6 over 5
Answer:
The answer is .578 you just do 5/6 due to the fact that there are 6 sides on a die and 1 side is a 2 so if you don’t get a two there is 5 sides left so you do 5/6 to the power of 3 leaving you with .578 and some
Step-by-step explanation:
Answer:
£189
Step-by-step explanation:
Divide the cost by 9 to find the cost of 1 ticket, then multiply this by 7
cost of 1 ticket = £243 ÷ 9 = £27
cost of 7 tickets = 7 × £27 = £189
Answer:
8.29
Step-by-step explanation:
It is 8.29 because the 3 is not greater than a 5, therefore it does not get rounded up.
Answer:
A = 0.84
Step-by-step explanation:
The absorbance of the myoglobin solution can be calculated by using the Beer-Lambert law:

<u>Where:</u>
<em>A: is the absorbance </em>
<em>ε: is the molar attenuation coefficient = 15,000 M⁻¹cm⁻¹ </em>
<em>l: is the optical path length = 1 cm</em>
<em>C: is the concentration = 1 mg/ml </em>
Since the concentration is given in mg/ml and the molar attenuation coefficient is given in M (mol/L) we need to convert the concentration in mg/ml to mol/L and for that, we need to use the molecular weight of myoglobin = 17.8 kDa = 17.8x10³ g/mol:

Now, we can calculate the absorbance of the myoglobin:

Therefore, the absorbance of the myoglobin solution is 0.84.
