A factory produces 80,000 candies each day. They produce equal quauntities of four flavors cherry lemon orange and strawberry. T

Stells [14]

Answer: $\dfrac14$

Step-by-step explanation:

Given: The factory produces equal quantities of four flavors cherry lemon orange and strawberry.

Let orange candy= cherry = lemon = strawberry = x

Total candies = x + x + x + x= 4x

The probability that a randomly selected candy is orange = $\dfrac{x}{4x}=\dfrac14$

Hence, the probability that a randomly selected candy is orange = $\dfrac14$

1.Mr. Bowen’s test is normally distributed with a mean of 75 and a standard deviation of 3 points.

lianna [129]

Answer:

2.28%

Step-by-step explanation:

Mr. bowens test is normally distributed with a mean (μ) of 75 and a standard deviation (σ) of 3 points.

The z score is used in probability to show how many standard deviation is a raw score below or above the mean. The formula for the z score (z) is given by:

$z=\frac{x-\mu}{\sigma}$

For a raw score (x) of 81 points, the z score can be calculated by:

$z=\frac{x-\mu}{\sigma}=\frac{81-75}{3}=2$

Therefore from the normal probability distribution table, the probability that a randomly selected score is greater than 81 can be given as:

P(x > 81) = P(z > 2) = 1 - P(z < 2) = 1 - 0.9772 = 0.0228 = 2.28%
