Absolute dating is used to determine a precise age of a rock or fossil through radiometric dating methods. This uses radioactive minerals that occur in rocks and fossils almost like a geological clock. It's often much easier to date volcanic rocks than the fossils themselves or the sedimentary rocks they are found in.

In a bag of candy, Marsha found that there were 7 red, 8 blue, 5 yellow, and 9 greens pieces of candy. Marsha put all of the pie
Lunna [17]

Answer:

PART A

  • Red: 7/29
  • Blue: 8/29
  • Yellow: 5/29
  • Green: 9/29

PART B

  • Red or blue: 7/29 + 8/29 = 15/29
  • Yellow or green: 5/29 + 9/29 = 14/29
  • Blue or yellow or green: 8/29 + 5/29 + 9/29 = 22/29

Explanation:

In this case where the question is asking or <u>OR</u> and the events are <u>mutually exclusive</u> (Mutually exclusive meaning you can't attain two or three different colors in one pick), the compound probability is the sum of the probability of each component event (Probability of Red <u>OR</u> Blue = P(Red) + P(Blue) = 7/29 + 8/29 = 15/29)

Christopher has at most \$18.50$18.50dollar sign, 18, point, 50 to spend at a convenience store. He buys one bag of bananas for
Juli2301 [7.4K]

Answer:

Amount to spend = $18.50

Purchased banana =$1.50

Apple Juice =$1.55

Gasoline $2.35

$1.50 + $1.55 = $3.05

18.50 - 3.05 = 15.45

1 Gallon of Gasoline = 2.35

Therefore,

2.35 x 6 = 14.1

15.35 - 14.1 = 1.25

To avoid exceeding budget, he can only buy

6 gallons of gasoline

In a recent year, about 22% of Americans 18 years and older are single. What is the probability that in a random sample of 200 A
Pie

Using the normal approximation to the binomial, it is found that there is a 0.0107 = 1.07% probability that more than 30 are single.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

Z = \frac{X - \mu}{\sigma}

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
  • The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with \mu = np, \sigma = \sqrt{np(1-p)}.

In this problem, the proportion and the sample size are, respectively, p = 0.22 and n = 200, hence:

\mu = np = 200(0.22) = 44

\sigma = \sqrt{np(1 - p)} = \sqrt{200(0.22)(0.78)} = 5.8583

The probability that more than 30 are single, using continuity correction, is P(X > 30.5), which is <u>1 subtracted by the p-value of Z when X = 30.5</u>, hence:

Z = \frac{X - \mu}{\sigma}

Z = \frac{30.5 - 44}{5.8583}

Z = -2.3

Z = -2.3 has a p-value of 0.0107.

0.0107 = 1.07% probability that more than 30 are single.
