Answer: 5th degree binomial

Note: You can say it's a quintic binomial but I find its easier to go with "5th degree" instead of "quintic" 

------------------------------------------------

How to get this answer:
The degree is the largest exponent for single variable polynomials such as this one. We see that 5 is the largest exponent, so the degree is 5. We consider this a quintic polynomial (think "quintuplets" which is how I remember). Though to be fair, the term "quintic" isn't used too much. Any degree larger than 4 you just state the number followed by "st", "nd", or "th" which is easiest I think. 

This is a binomial because it has 2 terms. The terms are separated by a minus sign or subtraction sign. We can think of it as adding a negative
17n^5 - n^4 = 17n^5 + (-n^4)
The two terms 17n^5 and -n^4 are separated by a plus sign. 
In general, terms of a polynomial are separated by either a plus sign or a minus sign.

Assume the upper arm length of males over 20 years old in the United States is approximately Normal with mean 39.2 centimeters (
MAVERICK [17]

Answer:

The interval [32.6 cm, 45.8 cm]

Step-by-step explanation:

According with the <em>68–95–99.7 rule for the Normal distribution:</em>  If \large \bar x  is the mean of the distribution and s the standard deviation, around 68% of the data must fall in the interval

\large [\bar x - s, \bar x +s]

around 95% of the data must fall in the interval

\large [\bar x -2s, \bar x +2s] 

around 99.7% of the data must fall in the interval

\large [\bar x -3s, \bar x +3s]

So, the range of lengths that covers almost all the data (99.7%) is the interval

[39.2 - 3*2.2, 39.2 + 3*2.2] = [32.6, 45.8]

<em>This means that if we measure the upper arm length of a male over 20 years old in the United States, the probability that the length is between 32.6 cm and 45.8 cm is 99.7%</em>

5. Adam drives his car with an average velocity of 85 km/h eastward. How long will it take him to drive
NISA [10]

Answer:

x = 6.59 hrs = about 6 hours, 35 minutes

Step-by-step explanation:

Adam drives at 85 km / h. Let's set up equivalent fractions to see how long if he drives 560 km.

\frac{85 km}{1  hr} = \frac{560 km}{x hr}

Cross-multiply:

85x = 560

Solve for x:

560/85 = x

<u>x = 6.59 hrs = about 6 hours, 35 minutes</u>
