We can calculate (62 + 90) / 2 = 76. it's <span>known that 95% lies between the mean and twice the standard deviation. </span><span>if the mean is "μ" and the standard deviation is "σ": </span><span>μ-2σ and μ+2σ. i</span><span>f μ=76, then </span><span>76+2σ = 90, so 2σ = 14, so σ = 7.
</span>
<span>the mean is 76 and the standard deviation 7. </span>
angle PQS is 71 ( the sum of angle 1 and 2)
25+46=71
1000 milligrams = 1 gram
122000 milligrams = 122 grams
<span> x =(10-√92)/2=5-√ 23 = 0.204 or </span><span><span>x =(10+√92)/2=5+√ 23 = 9.796 </span> </span>
