Due to manufacturing error, three cans of regular soda were accidentally filled with diet soda and placed in a 12-pack. Suppose that two cans are randomly selected from the 12-pack: a) Determine the probability that both contain diet soda. b) Determine the probability that exactly one is diet

Answers

Answer:

a) 2/44 = 0.045

b) 9/22 = 0.409

Step-by-step explanation:

a) The probability the first can is diet soda is 3/12.

The probability the second can is diet soda is 2/11.

The probability of both is (3/12) (2/11) = 2/44 ≈ 0.045.

Alternatively, you can use combinations:

₃C₂ × ₉C₀ / (₁₂C₂) = 2/44

b) If the first can is diet soda, and the second can isn't, the probability is (3/12) (9/11) = 9/44.

If the first can isn't diet soda, and the second can is, the probability is (9/12) (3/11) = 9/44.

The total probability is 9/44 + 9/44 = 9/22 ≈ 0.409.

Alternatively, using combinations:

₃C₁ × ₉C₁ / (₁₂C₂) = 9/22

on a family outing tyler bought 5 cups of hot cocoa and 4 pretzels for $18.50. Some of his family members would like a second serving, so he went back to the same food stand and bought another 2 cups of hot cocoa and 4 pretzels

Answers

Answer:

5c+4p = 18.50

2c+4p = 11.20

Cost of cup = $2.4

cost of pretzels = $1.625

Step-by-step explanation:

Note:

2 cups of hot cocoa and 4 pretzels for $11.30

Computation:

5c+4p = 18.50........eq1

2c+4p = 11.30........eq2

Where c = cost of cup

p = cost of pretzels

From eq1 - eq2

3c = 7.20

c = 2.4

Cost of cup = $2.4

5c+4p = 18.50

5(2.4) + 4p = 18.50

p = 1.625

cost of pretzels = $1.625

In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 23% of your total grade, each major test is worth 22.5%, and the final exam is worth 32%. Compute the weighted average for the following scores: 85 on the lab, 95 on the first major test, 91 on the second major test, and 76 on the final exam. (Enter your answer to one decimal place.)

Answers

Answer:

The weighted average for the following score is   [tex]W = 85.72[/tex]

Step-by-step explanation:

From the question we are told that

  The worth of the lab score is  23% of  total grade  i.e 0.23

   The worth of each major test is 22.5% of the total grade  0.225

   The  worth of the final  exam is  32% of the total  grade 0.32

   The  score on lab is 85  

    The score on first major test is 95

    The score on the second major test is 91

     The score on the final exam is  76

Generally the weighted average is mathematically represented as

     [tex]W  =  [0.23 *  85 ]+ [0.225 * 95] +  [0.225 * 91 ]+ [0.32 *76  ][/tex]

=>  [tex]W = 85.72[/tex]

[tex]2\frac{7}{8} =8\times2=16+7=23=\frac{23}{8}[/tex]

What is the volume of a matchbox which measures 11cm by 6.4cm by
3cm?5) Small boxes measuring 3cm by 2cm by 1cm are packed into a large box which measures 15cm by 12 cm by 10cm. What is the
volume of:
a) the small boxes?
b) the large box?
c) How many small boxes will fit into the large box?

Answers

Step-by-step explanation:

the volume of a box is always

length × width × height

in our first case here :

11 × 6.4 × 3 = 211.2 cm³

the volume of the small boxes is

3 × 2 × 1 = 6 cm³

the volume of the large box is

15 × 12 × 10 = 1,800 cm³

so,

1800/6 = 300 small boxes will fit into the large box.

because the dimensions of the small boxes are factors of the dimensions of the large box (3 is a factor of 15, 2 is a factor of 12, 1 is a factor of 10), it will be a perfect fill without any unused leftover pockets of space.

so, truly 300 small boxes will fit into the large box.

Answers

Pretty sure its not a unimodal/left skewed and right skewed as theres no sudden drop and the frequency are all similar

The given histogram is uniform histogram.

Since we know that,

A histogram is a graphical depiction of data distribution in statistics. The histogram is represented by a series of neighboring rectangles, with each bar representing a different type of data.

Statistics is a branch of mathematics that is used in a variety of areas. When numbers are repeated in statistical data, this repetition is known as Frequency, and it may be put down in the form of a table, which is known as a frequency distribution.

A Frequency distribution may be represented graphically using several types of graphs, one of which is a Histogram.

Based on the frequency distribution of the data, the histogram may be categorised into distinct categories. Normal distribution, skewed distribution, bimodal distribution, multimodal distribution, comb distribution, edge peak distribution, dog food distribution, heart cut distribution, and so on are all examples of distributions. These many sorts of distributions can be represented by the histogram.

A histogram can be of several types:

Histogram that is uniform

Histogram with symmetry

Histogram with two modes

Probability distribution histogram

A uniform distribution demonstrates that the number of classes is too small, with the same amount of components in each class. It might involve a distribution with many peaks.

Since we can see in the given histogram,

The average frequency  is 5

And almost all the bars are ending at 5

Hence,

This histogram is uniform histogram.
