Answer:
58%
Step-by-step explanation:
Out of 60 students who take math, 35 of them will also have science. The desired probability is ...
35/60 = 0.58333... ≈ 58%
__
More formally, ...
P(S | M) = P(S&M)/P(M)
= 35%/60% = 7/12 ≈ 58%
Answer:
pOH = 9.4
Step-by-step explanation:
Mathematically;
pH + pOH = 14
pOH = 14 - pH
But pH = -log[H3O+]
From the question [H3O+] = 2.5 * 10^-5
Thus pH = -log (2.5 * 10^-5)
pH = 4.6
Thus;
pOH = 14-4.6
pOH = 9.4

Compounded Interest Rate Formula:
- <em>P</em> is principle amount
- <em>r</em> is rate
- <em>n</em> is compounded rate
- <em>t</em> is time (in years)
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>P</em> = 1000
<em>r</em> = 10% = 0.1
<em>n </em>= 12
<em>t</em> = 4
