8+9×3-4= 31 do you need to show the work as well?
Answer:
<em>The probability of the length of a randomly selected Cane being between 360 and 370 cm P(360 ≤X≤370) = 0.6851</em>
Step-by-step explanation:
<u>step(i)</u>:-
<em>Let 'X' be the random Normal variable</em>
<em>mean of the Population = 365.45</em>
<em>Standard deviation of the population = 4.9 cm</em>
<em>Let X₁ = 360</em>
<em></em><em></em>
<em>Z₁ = -1.112</em>
<em>Let X₂ = 370</em>
<em></em><em></em>
<em>Z₂ = 0.911</em>
<u><em>Step(ii</em></u><em>):-</em>
<em>The probability of the length of a randomly selected Cane being between 360 and 370 cm</em>
<em> P(x₁≤x≤x₂) = P(z₁≤Z≤z₂) </em>
<em> P(360 ≤X≤370) = P(-1.11≤Z≤0.911)</em>
<em> = P(Z≤0.911)-P(Z≤-1.11)</em>
<em> = 0.5 +A(0.911) - (0.5-A(1.11)</em>
<em> = 0.5 +A(0.911) - 0.5+A(1.11)</em>
<em> = A(0.911) + A(1.11)</em>
<em> = 0.3186 + 0.3665</em>
<em> = 0.6851</em>
<em>The probability of the length of a randomly selected Cane being between 360 and 370 cm P(360 ≤X≤370) = 0.6851</em>

1,2,3,4,6,9,12,18 and 36. 1,2,3,6,9,18,27, and 54 .Although the numbers in bold are all common factors of both 36 and 54 ,18 is the greatest common factor. The second method to find the greatest common factor is to list the prime factors, then multiply the common prime factors
1/2 of 2 is 1
1/2 of 10 is 5...
5:1
The fraction 30/34 is equivalent to 15/17.
