8-3x=5*2
8-3x=10
-3x=10-8
-3x=2
x=-2/3
Answer:
1. 10 mg
2. an exponential
3. decreases only
Step-by-step explanation:
its correct
Because the answers are all in standard form, we can simply look for the intercepts of the graph.
x-int = (-6, 0)
y-int = (0, -2)
You must multiply these numbers by a coefficient to equal 12:


Solve both equations by dividing by their values:


Look for the answer with these coefficients. The answer is
-6x - 2y = 12.
Answer:
a) Null and alternative hypotheses are:
: mu=183 days
: mu>183 days
b) If the true mean is 190 days, Type II error can be made.
Step-by-step explanation:
Let mu be the mean life of the batteries of the company when it is used in a wireless mouse
Null and alternative hypotheses are:
: mu=183 days
: mu>183 days
Type II error happens if we fail to reject the null hypothesis, when actually the alternative hypothesis is true.
That is if we conclude that mean life of the batteries of the company when it is used in a wireless mouse is at most 183 days, but actually mean life is 190 hours, we make a Type II error.
