Let <span>f(x) = 2x + 2</span>
You'll see it is a straight line, slope 2 (which is positive, i.e. going uphill as we go left to right) and y-intercept 2.
Now let's consider <span>−f(x)</span>.
This gives us
<span>−f(x) = −2x − 2</span>
Answer:
She will need approximate of plastic border
Step-by-step explanation:
we know that
The circumference of a circle is equal to
In this problem we have
substitute
----> exact value of the length of plastic border
assume
---> approximate value of the length of plastic border
What are you even talking about... What is the ???
Answer:One can do a two-proportion test and find that the z-value for different is 1.28 (or -1.28, depending how one sets up the test).
The p-value for that is 0.20, so by most tests this is not statistically significant.
Said another way, if there had been no change in the interval, the probability of having a repeat sample at least this different would be 0.20.
The parameter one is attempting to determine is the true proportion of adults in the US who say they like pizza.
For those who think it is 50%, it is essentially 100% likely that it is not 50% but much higher, around 75-77%.
If you sketch the triangle you will see it is a right triangle with B being the vertex for the right angle. the orthocenter is the intercept of the three altitudes. for a right triangle, the orthocenter is the vertex where the right angle is.so the answer for this question is (-4,5)
