Let f(x)=x-2 and g(x)=x2-7x-9 fins f(g(-1))
vlabodo [156]
The answer is -3 because you’re plugging g(x) into f(x). For every x there is in f(x), plug in g(x)’s equation. After you get another equation (simplified), which is x^2 -7x -11, plug -1 for every x and condense.

Sammy's Sandwich Shop has a mean delivery time of 25 minutes with a standard deviation of 2 minutes. Determine the z-score for t
Jlenok [28]

Answer:the z score is - 1

Step-by-step explanation:

Assuming a normal distribution for the delivery time of sandwiches by Sammy's Sandwich Shop. We would apply the formula for normal distribution which is expressed as

z = (x - u)/s

Where

x = delivery times

u = mean delivery time

s = standard deviation

From the information given,

u = 25 minutes

s = 2 minutes

We want to determine the z-score for the number of sandwiches delivered in less than 23 minutes. It becomes

z = (23 - 25)/2 = - 1

<em>The question is mixed up with another (See comment for correct question)</em>

Given

Length = 799in

Width = 245in

Required

The perimeter of the deck (this is what the question implies)

The perimeter (P) is:

P =  2 * (Length + Width)

P =  2 * (799 + 245)

P =  2 * 1044

P =  2088

If you reflect the image over the x - axis, what are the new coordinates of the shape?
lutik1710 [3]

Greetings!

When reflecting a shape over the x-axis, you simply change the number to its opposite positive/negative equivalent.

This means that the new co-ordinates would be (-5,1) , (-5,4) and (-2,4).


Hope this helps!
