The average watermelon weighs 8 lbs with a standard deviation of 1.5. Find the probability that a watermelon will weigh between
Andrew [12]

Answer:

The  probability that a watermelon will weigh between 6.8 lbs and 9.3 lbs.

P(6.8 ≤X≤9.3) = 0.5932

Step-by-step explanation:

Step 1:-

by using normal distribution find the areas of given x₁ and x₂

Given The average watermelon weighs 8 lbs

μ = 8

standard deviation σ = 1.5

I) when  x₁ = 6.8lbs and  μ = 8 and  σ = 1.5

 z_{1}  = \frac{x_{1} -mean}{S.D} = \frac{6.8-8}{1.5} = - 0.8

ii)  when x₂ = 9.3 lbs and  μ = 8 and  σ = 1.5

z_{2}  = \frac{x_{2} -mean}{S.D} = \frac{9.3-8}{1.5} = 0.866>0

<u>Step2</u>:-

The probability that a watermelon will weigh between 6.8 lbs and 9.3 lbs.

P(6.8 ≤X≤9.3) = A(z₂) - A(-z₁)

                      = A(0.866) - A(-0.8)

                       =  A(0.866)+ A(0.8)

check below normal table

                      = 0.3051 + 0.2881

                      = 0.5932

<u>Conclusion</u>:-

The probability that a watermelon will weigh between 6.8 lbs and 9.3 lbs.

P(6.8 ≤X≤9.3) = 0.5932

Find the unknown length y in the pair of similar triangles.
oee [108]

Step-by-step explanation:

If 2 triangles are similar then the ratio of any 2 sides of one triangles will be equal to the ratio of any 2 sides of the another triangle.

So,

\frac{30}{8}  =  \frac{20}{y}

Cross-multiplying the denominators gives,

30y  = 160

=  > y =  \frac{160}{30}  =  \frac{16}{3}
