Answer:

Arrange students in groups of 2. Instruct students to first read through the problems and decide on what information they need to solve each problem. Record relevant information for all students to see. Only record information when students have asked for it. Possible information students will ask for include:Mai’s dad’s computer holds 500 gigabytes of storage space.A kilobyte is 1,000 bytes, a megabyte is 1,000,000 bytes, and a gigabyte is 1,000,000,000 bytes.1 character is roughly 1 byte.An emoji is roughly 4 bytes.A full-length, high-definition film is around 8 gigabytes and runs 2 hours.A person sleeps about 8 hours in a night.

Polynomial 5x^5-9x^3+2x^11+6

tresset_1 [31]

<span>So we have a polynomial 5x^5-9x^3+2x^11+6 and we are wondering what is its degree, leading coefficient, number term and the constant term. The degree of a polynomial is its highest power so here that is 11. Leading coefficient is the term with the highest degree of a polynomial and here thats 2. Number of terms is 4 because that many numbers are in this polynomial and the constant term is 6 beccause it is a constant. </span>

Suppose that time spent on hold per call with customer service at a large telecom company is normally distributed with a mean µ

lana66690 [7]

Answer:

0.3108 is the probability that the sample mean is between 7.8 and 8.2 minutes.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 8 minutes

Standard Deviation, σ = 2.5 minutes

Sample size, n = 25

We are given that the distribution of time spent is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

Standard error due to sampling =

$=\dfrac{\sigma}{\sqrt{n}} = \dfrac{2.5}{\sqrt{25}} = 0.5$

P(sample mean is between 7.8 and 8.2 minutes)

$P(7.8 \leq x \leq 8.2)\\\\ = P(\displaystyle\frac{7.8 - 8}{0.5} \leq z \leq \displaystyle\frac{8.2-8}{0.5})\\\\ = P(-0.4 \leq z \leq 0.4})\\\\= P(z < 0.4) - P(z < -0.4)\\\\= 0.6554 -0.3446= 0.3108$

0.3108 is the probability that the sample mean is between 7.8 and 8.2 minutes.

(x³ + 5x² - 9x - 13) ÷ (x + 6)

almond37 [142]

Answer:

$x^2-x-3+\frac{5}{x+6}$

Step-by-step explanation:

$\frac{x^3+5x^2-9x-13}{x+6} \\ \\ =\frac{x^2(x+6)-x^2-9x-13}{x+6} \\ \\ =\frac{x^2(x+6)-x(x+6)-3x-13}{x+6} \\ \\ =\frac{x^2(x+6)-x(x+6)-3(x+6)+5}{x+6} \\ \\ =x^2-x-3+\frac{5}{x+6}$
