Answer: 1% is your answer
It's (1/100) * 100 or 1% is the percentage strength of a 1:100 solution.
Step-by-step explanation:
l NOTE:
l To change ratio strength to percent strength, it is
sometimes convenient to "convert" the last two zeros in
a ratio strength to a percent sign (%),
l change the remaining ratio to a common fraction, and
then to a decimal fraction in expressing percent.
l Examples:
l 1:100 =1/1% = 1%
l 1:200 = ½% = 0.5%
l 3:500 = 3/5% = 0.6%
l 1:2500 = l/25% = 0.04%
l 1:10,000 = 1/100% = 0.01%
Answer:
75 inches
Step-by-step explanation:
with this we use change of subject
V=1/3
Pie=3.14
radius =3
height =8
so therefore
V=1/3 ×3.14×3×3×8
V=75.36
Answer:
11.84% approx.
Step-by-step explanation:
Expected return = Respective return × Respective probabilities
= (18.5 × 0.71) + (-7.6 × 0.29)
= 10.931%
Probability Return Probability ×(Return - expected return)²
0.71 18.5 0.71×(18.5 - 10.931)² = 40.67573
0.29 -7.6 0.29×(-7.6 - 10.931)² = 99.585409
Total = 140.261139%
![SD=[\frac{\text{total probability(return-expected return)}^2}{\text{total probability}}]^{(\frac{1}{2})}](https://tex.z-dn.net/?f=SD%3D%5B%5Cfrac%7B%5Ctext%7Btotal%20probability%28return-expected%20return%29%7D%5E2%7D%7B%5Ctext%7Btotal%20probability%7D%7D%5D%5E%7B%28%5Cfrac%7B1%7D%7B2%7D%29%7D)
= ![[\frac{140.261139^2}{140.261139}]^{\frac{1}{2} }](https://tex.z-dn.net/?f=%5B%5Cfrac%7B140.261139%5E2%7D%7B140.261139%7D%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D)
= 11.84319 ≈ 11.84% approx.
