Answer: 41%

Step-by-step explanation: Look at the prime numbers [2,3,5,7,11] and Add the amounts below them. (3+6 +11 +16 +5 = 41)

Then add up all the other amounts (this turns out to be 59, so the total rolls =100)

41/100 No calculator needed!

Answer:

x = 1 and x = 2

x = 4 and x = -4

Step-by-step explanation:

Vertical asymptotes appear where the function does not have a value. This is most commonly when the denominator of a rational function is 0. Find the asymptotes by factoring the denominator and setting it equal to 0. Then solve for x.

<u>First equation</u>

x² - 3x + 2 factors into (x-1)(x-2)

When x-1 = 0, x = 1. When x-2=0, x = 2. The V.A. are at x = 1 and x = 2.

<u>Second equation</u>

x² - 16 factors into (x+4)(x-4)

When x+4= 0, x = -4. When x-4 = 0, then x = 4. The V.A. are at x = -4 and x = 4.

Answer:

n=126

Step-by-step explanation:

Data given and previous concepts

$\bar X=60$ represent the sample mean

$s=11$ represent the sample deviation

n=32 represent the sample size

Confidence =0.95 or 95%

$\alpha =1-0.95=0.05$ represent the significance level

ME= 2 represent the margin of error required

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

Assuming the X follows a normal distribution

$X \sim N(\mu, \sigma)$
