For a certain​ candy, 15​% of the pieces are​ yellow, 5​% are​ red, 20​% are​ blue, 20​% are​ green, and the rest are brown. ​a) if you pick a piece at​ random, what is the probability that it is​ brown? it is yellow or​ blue? it is not​ green? it is​ striped?

Answers

Answer 1
Answer: P(Brown) = 100 - 15 -5- 20 - 20 = 40%

P(yellow or blue) = 15 + 20 = 35%

P(not green) = 100 - 20 = 80%

P(striped) = 0%

Which expression is equivalent to 3/ x^5y
\sqrt[3]{ {x}^(5)y }

Answers

Answer:

{x}^{ (5)/(3) }  {y}^{ (1)/(3) }

Step-by-step explanation:

A cube root is equivalent to the power of 1/3, so by taking the powers of the exponents and multiplying them by 1/3, you get your answer.

Answer:

\sqrt[3]{x^5 \  y } = (x^5 y)^(1)/(3)  = x^{ (5)/(3)} \ y^ { (1)/(3)}

In the past, 21% of all homes with a stay-at-home parent, the father is the stay-at-home parent. An independent research firm has been charged with conducting a sample survey to obtain more current information. (a) What sample size is needed if the research firm's goal is to estimate the current proportion of homes with a stay-at-home parent in which the father is the stay-at-home parent with a margin of error of 0.09? Use a 95% confidence level. (Round your answer up to the nearest whole number.)

Answers

Answer:

A sample size of 79 is needed.

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{(\pi(1-\pi))/(n)}

In which

z is the zscore that has a pvalue of 1 - (\alpha)/(2).

For this problem, we have that:

\pi = 0.21

The margin of error is:

M = z\sqrt{(\pi(1-\pi))/(n)}

95% confidence level

So \alpha = 0.05, z is the value of Z that has a pvalue of 1 - (0.05)/(2) = 0.975, so Z = 1.96.  

What sample size is needed if the research firm's goal is to estimate the current proportion of homes with a stay-at-home parent in which the father is the stay-at-home parent with a margin of error of 0.09?

A sample size of n is needed.

n is found when M = 0.09. So

M = z\sqrt{(\pi(1-\pi))/(n)}

0.09 = 1.96\sqrt{(0.21*0.79)/(n)}

0.09√(n) = 1.96√(0.21*0.79)

√(n) = (1.96√(0.21*0.79))/(0.09)

(√(n))^(2) = ((1.96√(0.21*0.79))/(0.09))^(2)

n = 78.68

Rounding up to the nearest whole number.

A sample size of 79 is needed.
