Find the area of the shaded region. The graph depicts the standard normal distribution with mean 0 and standard deviation 1
Digiron [165]

Answer:

P(z

And the best option would be:

0.8708

Step-by-step explanation:

We assume that the distribution for the random variable is:

X \sim N (\mu=0 , \sigma=1)

For this case we want to calculate the following probability:

P(z

And we can use the normal standard distribution or excel and we got:

P(z

And the best option would be:

0.8708

Can someone please help me Please I'm desperate

Answer:

James is 37, Rob is 44, and Kate is 35

Step-by-step explanation:

Set up an equation where x is James' age:

Rob's age can be represented by x + 7, since he is 7 years older than James

Kate's age can be represented by x - 2, since she is 2 years younger than James

Add these together in the equation and set it equal to 116:

(x + 7) + (x - 2) + (x) = 116

Add like terms and solve for x:

(x + 7) + (x - 2) + (x) = 116

3x + 5 = 116

3x = 111

x = 37

So, James is 37.

Find Rob's age by adding 7 to this:

37 + 7

= 44

Find Kate's age by subtracting 2:

37 - 2

= 35

So, James is 37, Rob is 44, and Kate is 35
