Suppose the mean income of firms in the industry for a year is 90 million dollars with a standard deviation of 15 million dollars. If incomes for the industry are distributed normally, what is the probability that a randomly selected firm will earn less than 109 million dollars? Round your answer to four decimal places.

Answers

Answer:

0.8980 = 89.80% probability that a randomly selected firm will earn less than 109 million dollars

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Distributed normally, mean of 90 million, standard deviation of 15 million.

This means that [tex]\mu = 90, \sigma = 15[/tex]

What is the probability that a randomly selected firm will earn less than 109 million dollars?

This is the pvalue of Z when X = 109. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{109 - 90}{15}[/tex]

[tex]Z = 1.27[/tex]

[tex]Z = 1.27[/tex] has a pvalue of 0.8980

0.8980 = 89.80% probability that a randomly selected firm will earn less than 109 million dollars

Which function is the inverse of f(x) = -5x - 4

Answers

Answer:

f(x) = -5x - 4 → x = -5y - 4 → 5y = - x - 4 → y = -⅕x - ⅘ → f-¹(x) = -⅕x - ⅘

A candy distributor needs to mix a 10% fat-content chocolate with a 60% fat-content chocolate to create
100 kilograms of a 25% fat-content chocolate. How many kilograms of each kind of chocolate must they
use?
Answer: They must mix
Kilograms of the 10% chocolate and
Kilograms of the 60% chocolate.

Answers

Answer:

They must mix 70 kilograms of the 10% chocolate and 30 kilograms of the 60% chocolate.

Step-by-step explanation:

Given that a candy distributor needs to mix a 10% fat-content chocolate with a 60% fat-content chocolate to create 100 kilograms of a 25% fat-content chocolate, to determine how many kilograms of each kind of chocolate must they use, the following calculations must be performed:

10 x 0.5 + 60 x 0.5 = 35

10 x 0.6 + 60 x 0.4 = 30

10 x 0.7 + 60 x 0.3 = 25

100 x 0.7 = 70

Thus, they must mix 70 kilograms of the 10% chocolate and 30 kilograms of the 60% chocolate.

A rectangular pool is drained of water until it is only half full.


If the length of the pool is 5.5m,
the breadth is 12m and the height is 18m, find the volume of water drained in liters.

Answers

Answer:

[tex]Volume = 594m^3[/tex]

Step-by-step explanation:

Given

[tex]Length = 5.5m[/tex]

[tex]Breadth = 12m[/tex]

[tex]Height =18m[/tex]

Required

The volume when it is half full

The height, when half full is:

[tex]h = 0.5 *Height[/tex]

[tex]h = 0.5 *18m[/tex]

[tex]h = 9m[/tex]

So:

The volume is:

[tex]Volume = Length * Breadth*h[/tex]

[tex]Volume = 5.5m * 12m * 9m[/tex]

[tex]Volume = 594m^3[/tex]

here are the approximate population of three countries, expressed in scientific notation: panama: 4 x 10^6 ; peru: 3.2 x 10^7 ; thailand: 7 x 10^7. Lin says that more than 20 times as many people live in thailand than in panama. Is this correct​

Answers

Answer:

No, Lin assumption is wrong

Step-by-step explanation:

Given

Population of panama = 4 x 10^6

population of thailand = 7 x 10^7.

Taking their ratios

thailand/panama = 7x 10^7/4 x 10^6

thailand/panama  = 7/4 * 10^7-6}

thailand/panama = 1.75 * 10^1

thailand/panama  = 17.5

thailand = 17.5 * panama

Hence the amount of people in thailand is not up to 20times those in panama. Hence Lin assumption is wrong

Using proportions, it is found that the ratio is of 17.5, hence Lin is not correct.

What is a proportion?

A proportion is a fraction of a total amount.

In this problem:

Thailand's population is of 7 x 10^7.Panama's population is of 4 x 10^6.

The ratio between the populations is given by:

r = 7 x 10^7/(4 x 10^6) = 1.75 x 10^1 = 17.5.

The ratio is of 17.5, hence Lin is not correct.

There are 40 balls in the bag. The probability of selecting a white ball is 28/40, simplified to 7/10. The probability of selecting a red ball is 12/40, simplified to 3/10. You are more likely to get a white ball so you will most likely lose $5.

Answer:

390 Millions of bacteria particles by the end of one week.

Step-by-step explanation:

The Bacteria Growth Rate Formula is:  ---> N (T) = N (0) * (1 + R) ^tT

N (0) = # of bacteria present during the beginning of the experiment

Variable R= Growth rate

Variable T= Time taken / elapsed.

Substitute the #'s for N (T)

N (0) and T from the given description

We then get the value of variable R.

220 = 20 * (1+R) ^ (24 hrs)

When solving for R, we get R = 0.105074

1 week= (7 x 24 = 168) hrs

We need to plug in the solutions

Therefore

N (168 hours) = 20 * (1+0.105074) ^168

Which is around 390 millions.

So now we know that there will be 390 millions of bacteria particles at the end of 1 week

Answers

Answer:

B

Step-by-step explanation:

To find your answer, simply multiply 2345 by 0.34. As 34% in decimal form is 0.34 and to find the percentage of a number, you must multiply the number with the percentage. When you do so, you get 797.3 exactly which is closest to 800 students, resulting in B being the answer. PS. Hamburgers every day would be disgusting and boring!!!!
