Answer:
The exponential function y = 2 ^ x has these properties:
A. The domain is the set of all real numbers.
B. The range is zero to infinity, (0, ∞).
C. The graph appears in Quadrants I and II and never touches the x-axis.
D. The function is always positive.
E. The inverse function of y = 2 ^ x is found b)y interchanging x and y here and solving x = 2^y for y: taking the natural log (ln) of both sides, ln x = y ln 2, so that y = (ln x) / (ln 2)
The above (E) can only be done if x is positive.
Answer:
x=5
y=6
Step-by-step explanation:
If you add the two, it turns into 2y=12. That means y=6. So then x would equal 5 if you bring y into one of them.
First, let's find the number of lunches:
14*3 = 42
To find how many lunches have ham sandwiches, we multiply the total number of sandwiches by the percentage of the ham sandwiches:
0.55 * 42
Multiply:
23.1
We can round down:
There are about 23 lunches with ham sandwiches
Answer: C
Explanation: 8^2 + 15^2 = 17^2
64+225=289
A type i error, as an example, is saying to a person that doesn't have ADHD, you have ADHD, or a false positive. A type ii error is saying to a person who does have ADHD, you don't have ADHD, or a false negative.
I hope this helped! :)
