<h3>
Answer: all real numbers greater than or equal to -3</h3>
Explanation:
The left-most point is at (-3,-2). The x coordinate is all we're concerned with here. The x coordinate for this point is x = -3. This is the smallest x value possible as an input. We cannot have x = -4 as that is nowhere on the blue curve.
So the domain is the set of real numbers x such that x is -4 or larger
In set builder notation, that would look like
In interval notation, we would say to indicate to the reader "have an interval from -3 to positive infinity; include the endpoint -3"
Answer: the answer would be 17, hope that helps
Step-by-step explanation:
Answer:
1/2
Step-by-step explanation:
The slope is the change in the y direction over the change in the x direction
6/12
1/2
Answer:
-3/4
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -4 - -7)/(-2-2)
( -4+7)/(-4)
3/-4
-3/4
Answer:
<u>The correct answer is A. -1.69</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Mean of the popping time of the kernels in a brand of microwave popcorn = 150 seconds
Standard deviation of the popping time of the kernels in a brand of microwave popcorn = 13 seconds
Time that first kernel pops = 128 seconds
2. What is the z-score of this kernel? Round your answer to two decimal places.
z-score = (Time that first kernel pops - Mean of the popping time)/Standard deviation of the popping time
Replacing with the real values, we have:
z-score = (128 - 150)/13
z-score = -22/13
<u>z-score = - 1.69</u>
<u>The correct answer is A. -1.69</u>
