Parcc chapter 7 pythagorean theorem

Mathematics
1 answer:
Bumek [7]3 years ago
7 0
So, we know that a^2 + b^2 = c^2.  Right?  That is called the Pythagorean Theorem.

In this case.  We can say that 39 is a, 40 is b, and x is c.
NOTE: It doesn't really matter whether 39 is a or b.  a & b are just the two legs of the right triangle.

So, if we say that 39 is a, 40 is b, and x is c.  We can plug it into the Pythagorean Theorem.

39^2 + 40^2 = x^2

I'll let you take it from there.

Answer:

3( n + \frac{17}{6} )² - \frac{361}{12} = 0

Step-by-step explanation:

3n² = 6 - 17n ⇔ 3n² + 17n - 6 = 0

3( n² + 2 × \frac{17}{6} n + ( \frac{17}{6} )² - ( \frac{17}{6} )² - 2 ) = 0

3( n + \frac{17}{6} )² - 3 × \frac{289}{36} - 6 = 0

3( n + \frac{17}{6} )² - \frac{361}{12} = 0

An insurance agent says the standard deviation of the total hospital charges for patients involved in a crash in which the vehic
lisov135 [29]
Let the null hypothesis be that the agent's claim is correct. Using a standard normal probability table we find:
p-value=P(Z \ \textgreater \ 1.1)=0.14
The p-value 0.14 is much larger than alpha = 0.01, so we cannot reject the agent's claim.
