Answer:
<em>The probability of spending between 4 and 7 days in recovery</em>
<em>P(4≤x≤7) = 0.5445</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given mean of the Population μ = 5.3 days
Given standard deviation of the population 'σ' = 2 days
Let 'X' be the random variable in normal distribution
Let x₁ = 4
Let x₂ = 7
<u><em>Step(ii):-</em></u>
<u><em>The probability of spending between 4 and 7 days in recovery</em></u>
<em>P(4≤x≤7) = P(-0.65≤Z≤0.85)</em>
<em> = P(Z≤0.85) - P(Z≤-0.65)</em>
<em> = 0.5 + A( 0.85) - ( 0.5 - A(-0.65) </em>
<em> = 0.5 + A( 0.85) - 0.5 +A(0.65) ( ∵A(-0.65) = A(0.65)</em>
<em> = A(0.85) + A(0.65)</em>
<em> = 0.3023 + 0.2422</em>
<em> = 0.5445</em>
<u><em>Final answer:</em></u><em>-</em>
<em>The probability of spending between 4 and 7 days in recovery</em>
<em>P(4≤x≤7) = 0.5445</em>

Answer:
The legs are 1.9 feet long
And the base is 1.1 feet long.
Step-by-step explanation:
Firstly, you need to find the value of x.
You need to add all the sides together:
2x - 0.3 + 2x - 0.3 + x
Simplified =
5x - 0.6
And this equals 4.9:
5x - 0.6 = 4.9
Next, you need to move the -0.6 over to the other side, making sure to make it a positive:
5x = 4.9 + 0.6
5x = 5.5
Now divide each side by 5:
x = 1.1
As the image is unclear of what side you are finding the length of:
2x - 0.3 = 1.9 feet long
And the base is 1.1 feet long.
