Answer:
91.92%
Step-by-step explanation:
Given that:
Mean (μ) = 6.2, standard deviation (σ) = 1.5
Z score is a measure in statistics to determine the relationship of a measured value with the mean. It is given by the equation:
To calculate the probability that a patient has a blood test result less than or equal to 8.3, we need to calculate the z score of 8.3
For x = 8.3, the z score is:
From the probability distribution table:
P( x ≤ 8.3) = P(z < 1.4) = 0.9192 = 91.92%

Answer:
y = - 8
Step-by-step explanation:
given slope m =
point (5, -2) for (x1, y1)
equation for point slope form
y - y1 = m(x- x1)
y - (-2) = (x -5)
y + 2 = x - 6, simplify
y = - 8,
further you can multiply by 5 to get rid of fraction
5y = 6x - 40
Answer:
$223.
Step-by-step explanation:
Let x be the original price of phone.
We are told that Terry sees this offer refurbished phone 35% off now only $78.
We need to find x such that 35% of x is 78. We can represent this information as:
Therefore, the original price of phone was $223.
