A sock drawer has 17 folded pairs of socks, with 5 pairs of white, 8 pairs of black and 4 pairs of blue. What is the probability, without looking in the drawer, that you will first select and remove a black pair, then select either a blue or a white pair?

Answers

Answer 1
Answer:

The probability of selecting a black pair of socks first, then a blue or white pair of socks is 27/136.

The probability of selecting a black pair of socks first is:

probability = (number of black pairs)/(total number of pairs)

= 8/17

Once a black pair of socks has been selected, there are 16 pairs of socks left in the drawer. Of these 16 pairs, 9 are either blue or white.

The probability of selecting a blue or white pair of socks second is:

probability = (number of blue and white pairs)/(number of remaining pairs)

= 9/16

Therefore, the overall probability of selecting a black pair of socks first, then a blue or white pair of socks is:

probability = (8/17)*(9/16)

= 27/136

Write an equation for the graph, where y depends on x.
The white "Spirit" black bear (or Kermode) Ursus americanus kermodei, differs from the ordinary black bear by a single amino acid change in the melanocortin 1 receptor gene (MC1R). In this population, the gene has two forms (or alleles): the "white" allele b and the "black" allele B. The trait is recessive: white bears have two copies of the white allele of this gene (bb), whereas a bear is black if it has one or two copies of the black allele (Bb or BB). Both color morphs and all three genotypes are found together in the bear population of the northwest coast of British Columbia. If possessing the white allele has no effect on growth, survival, reproductive success, or mating patterns of individual bears, then the frequency of individuals with 0, 1, or 2 copies of the white allele (b) in the population will follow a binomial distribution. To investigate, Hedrick and Ritland (2011) sampled and genotype 87 bears from the northwest coast:42 were BB 24 were Bb 21 were bb Assume that this is a random sample. A formal hypothesis test was carried out to compare the observed and expected frequencies of genotypes. The procedure obtained P = 0.0001. 1.

Which descriptions of a histogram are true? Check all that apply..A peak is a bar that is lower than the other bars around it.
A peak is where the frequency is lowest.
A peak is where the frequency is the highest.
A cluster is a group of bars, meaning the frequency is higher in these intervals.
A peak is a bar that is higher than the other bars around it.
Intervals on a histogram where there are no bars mean the frequency is 0.
If the graph is symmetrical, the data is clustered toward the right side.
If the graph is symmetrical, the data is evenly distributed.

Answers

The correct statement about histogram is as follows;

A peak is where the frequency is the highest.

A cluster is a group of bars, meaning the frequency is higher in these intervals.

A peak is a bar that is higher than the other bars around it.

Intervals on a histogram where there are no bars mean the frequency is 0.

If the graph is symmetrical, the data is evenly distributed.

We have to determine, which descriptions of a histogram are true?

According to the question,

A histogram meaning can be stated as a graphical representation that condenses a data series into an easy interpretation of numerical data by grouping them into logical ranges of different heights which are also known as bins.

Characteristics of a Histogram are as follows;

A histogram is used to display continuous data in a categorical form.  

In a histogram, there are no gaps between the bars, unlike a bar graph.  

The width of the bins is equal.

A histogram is a type of representation of a data set where bars are used to represent the frequencies.

The area of these bars is said to be proportional to the frequency of the variable.

The peak of a histogram represents the highest value of frequency. Also, the peak is a bar that is higher than the other bars around it.

In a histogram intervals wherein bars cannot be seen would represent the frequency of that would zero.

Also, if the histogram is said to be symmetrical, then the data should be distributed evenly.

A peak is where the frequency is the highest.

A cluster is a group of bars, meaning the frequency is higher in these intervals.

Earlier we analyzed the revenue earned by the junior class at East High School from their discount card fundraiser. They hada goal to earn a profit of more than $10,000 from the fundraiser.
Since the local area businesses are supporting the fundraiser, the only cost to the students is the production cost. So, the
profit from the cards is found by subtracting the total production cost from the total revenue. Each card costs $0.20 to
produce and is sold for $20.
Select the correct answer from each drop-down menu.
If the class sold c cards, the inequality that represents their profit goal is
This year's class sold 520 cards, so they
their goal because they sold more than
cards.

Answers

Approximately 520 cards actually sold this year in the class, more than 505, have fulfilled their objective.

According to the question,

If the students sell c cards the,

The total revenue,

  • 20c

The total production costs,

  • 0.2c

`

The inequality of profit, or income, which is less than 10 thousand dollars represents their objective, such as:

20c-0.2c>10,000

→         19.8c>10,000

→               c > (10,000)/(19.8c)

→               c> 505.05

or,

→               c>505

The class had to sell more than 505 cards just to meet their goals.

Thus the above answer is right.
