A normal distribution has a mean of 10 and a standard deviation of 1. What is the probability of selecting a number that is at m
Len [333]

Answer: 0.500

Step-by-step explanation:

Given : A normal distribution has a mean(\mu) of 10 and a standard deviation(\sigma) of 1.

Let x be a random variable that represents numbers .

The probability of selecting a number that is at most 10 will be

P(x\leq10)=P(\dfrac{x-\mu}{\sigma}\leq\dfrac{10-10}{1})\\\\=P(z\leq0)=0.500

As the area occupied by standard normal curve less than equal to 0 = 0.500

So, required probability = 0.500

Function lis defined by the equation r
Amiraneli [1.4K]

Answer:

Both have the same y-intercept (-9)

Step-by-step explanation:

✔️Function 1, r = ⅝t - 9, is given in the slope-intercept form, y = mx + b.

b = y-intercept = -9

y-intercept for Function 1 = -9

✔️Function 2, using the table given, the y-intercept is the value of r when t = 0.

Thus, r = -9 when t = 0.

y-intercept for Function 2 = -9

✔️Both functions has the same y-intercept. None is greater than the other.
