Your answer should be 0.0946666666
Answer:
The probability that can afford to spend between $800 and $900
P(800≤X≤900) = 0.6826
The percentage of that can afford to spend between $800 and $900
P(800≤X≤900) = 68 percentage
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the mean of the Normal distribution = $850
Given that the standard deviation of the Normal distribution = $50
Let 'X' be a random variable in a normal distribution
Let x₁ = 800
![z_{1} = \frac{x_{1}-mean }{S.D} = \frac{800-850}{50} = -1](https://tex.z-dn.net/?f=z_%7B1%7D%20%3D%20%5Cfrac%7Bx_%7B1%7D-mean%20%7D%7BS.D%7D%20%3D%20%5Cfrac%7B800-850%7D%7B50%7D%20%3D%20-1)
Let x₂ =850
![z_{2} = \frac{x_{2}-mean }{S.D} = \frac{900-850}{50} = 1](https://tex.z-dn.net/?f=z_%7B2%7D%20%3D%20%5Cfrac%7Bx_%7B2%7D-mean%20%7D%7BS.D%7D%20%3D%20%5Cfrac%7B900-850%7D%7B50%7D%20%3D%201)
<u><em>Step(ii):-</em></u>
The probability that can afford to spend between $800 and $900
P(800≤X≤900) = P(-1≤Z≤1)
= P(Z≤1) - P(Z≤-1)
= 0.5 + A(1) - (0.5 - A(-1))
= A(1) +A(-1)
= 2× A(1) (∵ A(-1) =A(1)
= 2 × 0.3413
= 0.6826
The percentage of that can afford to spend between $800 and $900
P(800≤X≤900) = 68 percentage

= 75
Answer is (D). -6-7x. Or to play with it a lil bit -7x-6. The numbers and coefficients and signs are all correct doesn’t matter how you form them unless “they” disagree with it
Answer: Circumference
Step-by-step explanation: The distance around a circle on the other hand is called the circumference (c). Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r). Consider marking this answer as brainliest if it helped you out.
