Answer:

A=138

Step-by-step explanation:

First you would multiply 18 times 8, which equals 144. Then you would subtract 6, which equals 138. So A=138.

Answer:

A = 138

Step-by-step explanation:

[tex] \frac{a + 6}{8} = 18 \\ a + 6 = 18 \times 8 \\ a + 6 = 144 \\ a = 144 - 6 \\ a = 138[/tex]

Answer:

Step-by-step explanation:

Let w be the width

Length = w + 3

Perimeter = 40 m

2*(length + width) = 40

2*(w+3 + w) = 40

2* (2w + 3) =40

2w + 3 = 40/2

2w + 3 = 20

2w = 20-3

2w = 17

w = 17/2 = 8.5 m

w = 8.5 m

Length = w + 3 = 8.5 + 3 = 11.5m

Your question relates to probability in mathematics. Using various statistics techniques, we can solve these kinds of problems. However, you need to provide a specific question for further assistance.

The subject of your problem refers to probability, which is a field of mathematics. According to the data given, we can determine or estimate the random events' likelihoods, such as Ms. Zanetti receives text messages throughout her workday from her daughter’s daycare provider, the probability of being the first in line to get a prize, or the arithmetic of random numbers for samples selection in statistics, etc.

One common way we use in probability is setting up the equation and solve it. Another method is using statistical elements, such as mean, to solve the problem. For instance, If Leah receives, on average, 6 telephone calls in two hours, and there are eight 15-minute intervals in two hours, then Leah receives on average 0.75 calls in 15 minutes.

The probability of receiving exactly 4 text messages is 3/16.

The probability that she receives fewer than 4 text messages per day is 13/16

The probability that she receives at least 2 text messages per day is 5/8.

How to find the probability ?

To find the probability that Ms. Zanetti receives exactly 4 text messages per day, we can simply look at the probability given in the table.

Probability that Ms. Zanetti receives fewer than 4 text messages per day:

P(fewer than 4 text messages) = P(0 text messages) + P(1 text message) + P(2 text messages) + P(3 text messages)

= (1/8) + (1/4) + (3/8) + (1/16)

= (2/16) + (4/16) + (6/16) + (1/16)

= 13/16

The probability that Ms. Zanetti receives at least 2 text messages per day:

P(at least 2 text messages) = P(2 text messages) + P(3 text messages) + P(4 text messages)

= 3/8 + 1/16 + 3/16

= 6/16 + 1/16 + 3/16

= (6 + 1 + 3)/16

= 10/16

= 5/8

Answer:

0.67 repeated or 2/3 gallons

Step-by-step explanation:

First you divide the gallons by hours because you are doing gallons per hour.

Then you get 0.66666667 and you convert that to fraction and that's your answer.

The scientist uses about 0.67 gallons of liquid for each hour of work, as per the calculation obtained by dividing the total gallons of liquid he uses (2 gallons) by the total hours he works (3 hours).

The question here is asking how much of a gallon of liquid a scientist uses each hour if he uses 2 gallons of liquid every 3 hours. To find this, we can start by establishing the ratio of gallons to hours, which is 2 gallons per 3 hours. To find out how much of a gallon each hour he uses, we simply divide the total gallons (2) by the total hours (3).

So, to do this, we take 2 gallons ÷ 3 hours. That equals approximately 0.67 gallons per hour. Therefore, the scientist is using around 0.67 gallons of liquid for each hour he works.

3. The joint probability, P(A∩B), is the probability that a student takes Spanish and biology:

4. By the properties of probabilities, the probability of the event A or B is:

Final answer:

To find the probability of a student taking Spanish or Biology, you need to consider the students taking each subject and those taking both, applying the principle of inclusion-exclusion. The simplified probability is [tex]\frac{17}{28}[/tex].

Explanation:

The probability that a student selected at random takes Spanish or Biology can be calculated using the principle of inclusion-exclusion.

Find the total number of students taking Spanish or Biology: 550 + 700 - 400 (students taking both) = 850.

Calculate the probability: P(Spanish or Biology) = Number of students taking Spanish or Biology ÷ Total number of students = [tex]\frac{850 }{ 1400} = \frac{17}{28}[/tex].

Answer:

5/12

1/6+1/4=5/12

To determine the fraction of puppies that are black or white, you add 1/6 and 1/4, which gives you 5/12 when using a common denominator of 12. Therefore, 5/12 of the puppies are either black or white.

To find out what fraction of the puppies in the pet store are black or white, we simply add the fractions that represent the black puppies and the white puppies together. Since 1/6 of the puppies are black and 1/4 are white, we can write:

[tex]\(\frac{1}{6} + \frac{1}{4}\)[/tex]

To add these fractions, we need a common denominator. The least common multiple of 6 and 4 is 12, so we convert each fraction to have a denominator of 12:

[tex]\(\frac{1}{6} = \frac{2}{12}\) and \(\frac{1}{4} = \frac{3}{12}\)[/tex]

Now, we add the fractions:

[tex]\(\frac{2}{12} + \frac{3}{12} = \frac{5}{12}\)[/tex]

Therefore, 5/12 of the puppies are either black or white.

Answer:

Here is a screenshot of the finished work i've done!

Step-by-step explanation: Here, we want to find the mean, median, and mode for the data set. Let's begin by finding the mean.

The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set. So to find the mean of the data set shown here, let's begin by adding the numbers.

So we have

120 + 140 + 164 + 158 + 161 + 292 + 128 + 145 + 163 + 127 + 159 + 155.

This will be divided by how many numbers are in the set which is 12.

[tex]So[/tex] [tex]we[/tex] [tex]have[/tex] [tex]\frac{120 + 140 + 164 + 158 + 161 + 292 + 128 + 145 + 163 + 127 + 159 + 155}{12}[/tex].

Adding the numbers, we get 1,912.

1,912 is divided by the number of numbers in the set or 12.

1,912 divided by 12 is about 159.3333.

So the mean of the set of data shown here is about 159.3333.

Next, let's find the median.

The median is the middle number in the data set when the data set is written from least to greatest. So let's write our data set from least to greatest.

So we have 120, 127, 128, 140, 145, 155, 158, 159, 161, 163, 164, 292.

In this data set however, notice that there is no one middle number. When there is no middle number in a data set, we take the two numbers that are in the middle and we take the average of those numbers.

In this set, the two middle numbers are 155 and 158 because if we group these numbers together, there are five numbers on either side of them.

Now, to find the average of 155 and 158, we simply add them together and divide by 2. So we have 155 + 158 which is 313. Now, 313 ÷ 2 is 156.5.

So the median of the data set is 156.5.

Finally, let's find the mode.

The mode is the number that appears most frequently in a data set.

Notice that each number in our data set appears only once so there is no mode.

Answer:

120, 140, 164, 158, 161, 292, 128, 145, 163, 127, 159, 155

List the following data from least to greatest:

120, 127, 128, 140, 145, 155, 158, 159, 161, 163, 164, 292

Median: 156.5  

Mode: There are no mode in the following data set.

Mean: 120 + 127 + 128 + 140 + 145 + 155 + 158 + 159 + 161 + 163 + 164 + 292 = 1,912/12 = 159.3

1) P(A) = 0.20

2) P(B) = 0.80

3) P(A and B) = 0.15

4) P(A or B) = 0.85

Step-by-step explanation:

Total number of customers = 20

Customers with enough cash = 4

Customers with credit card = 16

Customers with enough cash and credit card = 3

Part 1) Customer has enough cash

Probability is defined as the ratio of favorable outcomes to total number of outcomes. Here the favorable outcome will be the customers with enough cash which are 4 in number and total number of outcomes will be the total number of customers which is 20.

Therefore, the probability that a customer has enough cash will be:

[tex]P(A)=\frac{4}{20}=\frac{1}{5}=0.20[/tex]

Part 2) Customer with a credit card

Using the same formula we used in previous part. However, in this case the number of favorable outcomes will be the number of customers with a credit card i.e. 16

Therefore, the probability that a customer has a credit card will be:

[tex]P(B)=\frac{16}{20} =\frac{4}{5} =0.8[/tex]

Part 3) Customer has enough cash and a credit card

Using the same formula once again. However, in this case the number of favorable outcomes will be the customers with enough cash and a credit card which is 3.

Therefore, the probability that a customer has enough cash and a credit card will be:

[tex]P(A \cup B)=\frac{3}{20}=0.15[/tex]

Part 4) Customer has enough Cash or a Credit Card

We need to find union of two events i.e. P(A or B). The union of two events is defined as:

P(A or B) = P(A) + P(B) - P(A and B)

We calculated all these values in the previous parts. Substituting the values in above formula, we get:

P(A or B) = 0.2 + 0.8 - 0.15

P(A or B) = 0.85

Therefore, the probability that a customer has enough cash or a credit card is 0.85
