A thumbtack that is tossed can land point up or point down. The probability of a tack landing point up is 0. 2. A simulation was conducted in which a trial consisted of tossing 5 thumbtacks and recording the number of thumbtacks that land point up. Many trials of the simulation were conducted and the results are shown in the histogram.

Answers

Answer 1

Histograms are used to represent data using bars.

The probability that at least 2 thumbtacks land pointing up when 5 thumbtacks are tossed is 0.28

The probability that at least 2 thumbtacks land pointing up when 5 thumbtacks are tossed is calculated using the following complement rule:

\(P(x \ge 2) = 1 - P(0) - P(1)\)

Using the values on the histogram (see attachment), we have:

\(P(x \ge 2) = 1 - 0.33 - 0.39\)

\(P(x \ge 2) = 0.28\)

Hence, the probability that at least 2 thumbtacks land pointing up when 5 thumbtacks are tossed is 0.28

Yesterday, the price of a gallon of gas at five gas stations was $3.56, $3.71,
$3.62, $3.93, and $3.83, respectively, but today each gas station raised its
price by $0.08. What iS today's mean price of a gallon of gas at the five
stations?
• A. $3.89
B. $3.81
• C. $3.73
D. $3.65

Answers

Answer: B. $3.81

Explanation:

First, to find the mean, add up all the numbers, then divide by how many numbers there are.

So $3.56, $3.71, $3.62, $3.93, and $3.83 in total is $18.65.

$18.65 divided by 5 is $3.73.

Now the question it says that today, each gas station raised its

price by $0.08. So you're gonna add $3.73 + $0.08 which equals to $3.81.

B. $3.81 is the answer.

The reaction 2hgo (s)→2hg (i)+o2 (g) has a percent yield of 50%. You want to produce 100 g of hg. How much hgodo you need? 54 g 108 g 216 g 432 g.

Answers

The mass of HgO needed for 100 g of hg is 108 g

Finding the  theoretical yield of Hg.

Given that

Actual yield of Hg = 100 g
Percentage yield = 50%

Then Theoretical yield of Hg = Actual yield / percentage yield

Theoretical yield = 100 / 50%

Theoretical yield = 100 / 0.5

Theoretical yield of Hg = 200 g

Calculating the mass of HgO needed for the reaction.

Equation of the reaction: 2Hgo (s)→2hg (l)+O2 (g)

Molar mass of HgO = 201 + 16 = 217 g/mol

Molar mass of Hg = 201 g/mol

Recall that ,

Number of moles= mass/ Molar mass

Therefore,

Mass of HgO (according to balanced equation)

= 2 × 217 = 434 g

Mass of Hg from the balanced equation = 2 × 201 = 402 g

Now,Having known that

434 g of HgO produces 402 g of Hg

200 g of Hg will be produce by = (200 × 434) / 402 = 216 g of HgO.

We can conclude that if 200 g of Hg is prodced by  216 g of HgO.

100g wll be produced by (216 x100 ) / 2=108g

Thus,to  produce 100 g of hg,  108g of HgO is needed.

Why can Dry food such as instant noodles, biscuits and potato chips be stored for a long time

Answers

Answer:

Dry foods such as instant noodles, biscuits and potato chips can be stored for a long time because they contain very little moisture. Moisture is what causes food to spoil quickly. Dry foods that contain less than 10 percent of moisture are the perfect candidates for long-term storage. Anything higher than ten could be difficult. 13% is a crucial number, with any foods higher than that posing too high of risk towards bacteria, mold, and fungus growth.

To store dry food properly, it should be kept in a cool and dry place. The storage temperature helps determine the length of storage; the higher the temperature, the shorter the storage time. Dried foods are susceptible to insect contamination and moisture reabsorption and must be properly packaged and stored immediately.
