Answer:

Part I:

1. binomial

2. trinomial

3. monomial

4. monomial

Part ll :

5. 8xy2 + 6xy + 5y + 12

6. 9x4 + 3x7 - 4x2 + 34x

Part lll:

7. (p3+5p2+9p-6)+(5p3-8p+1)

= p3 + 5p2 + 9p - 6 + 5p3 - 8p + 1

= 6p3 + 5p2 + p - 5 ( add all the like terms i. e. those terms having the same power)

8. (2p4+3p+9) +(4p4+3p3+p)

= 2p4 + 3p + 9 + 4p4 + 3p3 + p

= 6p4 + 3p3 + 4p + 9 ( adding all the like terms i. e. those terms having same power )

Please help me find the volume! :D

pantera1 [17]

The volume of the cylinder is 31.4 in³.

The volume can be calculated with the following formula:

V= $\pi$ r²h

V= $\pi$ ×1² in×10 in

V= $\pi$ ×10 in²

V≈31.4 in³

The ability to find a job after graduation is very important to GSU students as it is to the students at most colleges and unive

Murrr4er [49]

Answer:

(0.806, 0.839)

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

Suppose we take a poll (random sample) of 3653 students classified as Juniors and find that 3005 of them believe that they will find a job immediately after graduation.

This means that $n = 3653, \pi = \frac{3005}{3653} = 0.823$

99% confidence level

So $\alpha = 0.01$ , z is the value of Z that has a pvalue of $1 - \frac{0.01}{2} = 0.995$ , so $Z = 2.575$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.823 - 2.575\sqrt{\frac{0.823*0.177}{3653}} = 0.806$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.823 + 2.575\sqrt{\frac{0.823*0.177}{3653}} = 0.839$

The answer is (0.806, 0.839)

Answer:

She saves 24 cents by buying 24 oranges at store B

Step-by-step explanation:

Price per orange A = 6.48 / 12 oranges = .54 per orange

.54 * 24 oranges = 12.96 for store A

Price per orange B = 2.65 / 5 = .53 per orange

.53 * 24 oranges = 12.72 for store B

12.96 - 12.72 = .24 dollars (24 cents)
