4. (5 x 3) x 2 = 5 x (3 x 2) is an example of which property?
A) Commutative Property for Addition
B) Associative Property for Multiplication
O C) Distributive Property for Multiplication
D) Commutative Property for Multiplication

Answers

Answer:

B, Associative property for multiplication

Step-by-step explanation:

Commutative property means the numbers can be multiplied in any order, so the (5 x 3) x 2 could be written as 3 x 5 x 2 and would be the same.

Associative property deals more with groupings of terms/numbers. Since the order of the numbers stayed the same, and the parentheses are moved, this is an example of the associative property.

The answer would be b

Answer please 9 - (-4).

Answers

answer: 13
explain: at the like terms
it’s 13 because when there is a in front of an expression in parentheses, change the sign of each term in the expression so the - would turn into a + and it would be 9+4 basically so it’s 13

A town has a population of 5000 and grows at 3.5% every year. To the nearest tenth of a year, how long will it be until the population will reach 7300?

Answers

Answer:

Step-by-step explanation:

This is an exponential function. In order to find the answer to the question, we need to first determine what the equation is that models this information. The standard form for an exponential function is

where a is the initial value and b is the growth/decay rate. If the starting population is 5000, then

a = 5000

If the population is growing, that means that it retains 100% of the initial population and is added to by another 3.5%. So in a sense the population grows 100% + 3.5% = 103.5% or, in decimal form, 1.035. So

b = 1.035

Our function is

where y is the ending population and x is the number of years it takes to get to that ending population. We want to know how long, x, it will be til the population reaches 7300, y.

and we need to solve for x. The only way to do that is by using logs. I'll use natural logs for this.

Begin by dividing both sides by 5000 to get

and take the natural log of both sides:

The power rule for natural logs is that we can now bring the exponent down in front of the ln to get:

To solve for x, we now divide both sides by ln(1.035):

Do that division on your calculator and get that

x = 11.0 years.

That means that 11 years after the population was 5000 it will be expected to reach 7300 (as long as the growth rate remains 3.5%)

A scale model of a rectangular building lot measures 7feet by 5 feet. If the actual house will be built using a scale factor of 12 what is the area of the actual building lot

Answers

Actual area of the rectangular building = 5040 feet²
Step-by-step explanation:
Length of the rectangular building = 7 feet
Width of the rectangular building = 5 feet
Now, The building is made with a scale factor of 12
So, Actual length of the rectangular building = 84 feet
Actual width of the rectangular building = 60 feet
Now, Actual area of the rectangular building = Length × Width
⇒ Actual area of the rectangular building = 84 × 60
⇒ Actual area of the rectangular building = 5040 feet²

Clinical literature reports that the duration of a typical cold is roughly 18 days. Researchers wanted to know if people tend to underestimate the duration of a typical cold, on average. They surveyed a random sample of 352 healthy adults in Georgia and asked them how long they think that a typical cold lasts. The researchers reported a 95% confidence interval of 6.9 to 8.2 days for the mean expected duration of typical cold.
Which of the following is the correct interpretation for this confidence interval?
a. We are 95% confident that the sample mean duration is between 6.9 and 8.2 days.
b. We are 95% confident that the population mean duration is between 6.9 and 8.2 days.
c.There is a 95% chance that the mean duration of another random sample from this population would be between 6.9 and 8.2 days.
d. There is a 95% chance that a randomly selected individual from this population would give a response between 6.9 and 8.2 days.

Answers

Answer:

b. We are 95% confident that the population mean duration is between 6.9 and 8.2 days.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

95% confidence interval of 6.9 to 8.2 days for the mean expected duration of typical cold.

This means that we are 95% sure that the true duration of a typical cold(population mean) for all health adults in Georgia is between 6.9 and 8.2, which means that the correct answer is given by option b.

The variable z varies jointly with x and y. Also, z = -75 when x = 3 and y = -5.

What equation describes this variation?

x = kyz
y = kxz
z = kxy
k = xyz

Answers

What equation describes this variation?

z = kxy

What is the constant of variation?

k = 5

When x = 1 and y = –2, z =

-10

Step by Step Explanation:

With the equation z = kxy and the values for z, x, and y, we can find k.

z = kxy

-75 = (k) (3) (-5)

-75 = (k) (-15)

5 = k

k = 5 (final answer).

To check our work, we just enter all of the values and make sure it adds up.

z = kxy

-75 = (5)(3)(-5)

-75 = 15(-5)

-75 = -75

correct!

okay so, everytime you see anything that says "a number", that will automatically mean that there is a number in the equation that u dont know, so instead of putting a random number in its place, you put an "exponent" aka a letter like "x" for example. so it says, 12 is the sum of a "number" and 3, that means 3 plus a number gives u 12, you would have to make an equation to find the "number" so the equation would be "3 + x = 12".

2. The ratio of the angle measures in a
triangle is 1:12:17. What is the measure of
smallest angle?

Answers

Answer:

6 degrees

Step-by-step explanation:

x + 12x + 17x = 180

x = 6

The angles are 6 : 72 : 102 so the smallest is 6 degrees.

Answer:

sum of all angles = 180

given angle 1 X., 12 X, 17 X

SO 1 X + 12 X + 17 X= 180

13 X+17 X =180

30 X =  180

X=180\30

X =6

ANS =6

HOW; PUT X = 6  APPLY  TO  1 X., 12 X, 17 X

1 X=1×6= 6

12X = 12×6 =72

17 X = 17 ×6 =102

ANS = 6

Suppose lightning strikes at an average of 1.4 strikes per minute during a particular storm. You play the following game: if the next strike occurs within the next minute, you win 3 dollars, if the next strike occurs between 1 minute and 2 minutes from now, you win 5 dollars, and if the next strike occurs more than 2 minutes from now, you win 1 dollar. How much should someone be charged to play this game, to make it a "fair game?"

Answers

Answer:

$3.25

Step-by-step explanation:

Given that:

Mean, λ = 1.4

Strike within next minute = $3 won

Strike between one and 2 minutes = $5

Strike more than 2 minutes = $1

Probability that next strike occurs within the next minute :

Using poisson :

P(x < 1) = 1 - e^-(λx) ;

P(x < 1) = 1 - e^-(1.4*1) = 1 - e^-1.4

P(x < 1) = 1 - 0.2465969

P(x < 1) = 0.7534030

Next strike occurs between 1 and 2 minutes :

(1 < x < 2) :

P(x < 2) - P(x < 1)

P(x < 2) = 1 - e^-(λx) ;

P(x < 2) = 1 - e^-(1.4*2) = 1 - e^-2.8

P(x < 2) = 1 - 0.0608100

P(x < 2) = 0.9391899

P(x < 2) - P(x < 1)

0.9391899 - 0.7534030 = 0.1857869

P(striking after 2 minutes)

P(x > 2) = e^-(λx) ;

P(x > 2) = e^-(1.4*2) = e^-2.8

P(x > 2) = 0.0608100

Amount charged :

(0.7534030 * 3) + (0.1857869 * 5) + (0.06081 * 1)

= 3.2499

= $3.25

Economia de mercado prega a total liberdade de seus participantes, para o floxo de trocas de mercadorias e o mnimo de interveno estatal. Essa forma de ecomonia refere-se a: Bubbly Burst, the healthy fun chew. This was the popular promotion for the leading chewing gum on the market. The parent company for the item, Confectionary Plus, had incorporated a variety of promotional tools to build brand awareness over the years. Besides its range of exotic flavors, the company boasted the reduced sugar content of its products. The company also often included in its ads that sharp persons consumed the gum when they needed a healthy boost. The ads were also tailored to appeal to kids with similar messages and was well distributed in schools and vending machines. After three years of such promotion, the product was now a regular staple in the lunch bag of kids as well as in the pockets of most adults.The success was largely due to the leadership of Peter Hinds, CEO of Confectionary Plus. Hinds was the brainchild behind the marketing and advertising thrusts. Company shareholders were well pleased with his overall results. Behind the scenes though there was a lot going on in the company. While the product did indeed have a reduced sugar content, the artificial sweetener used in the gum had been found to have potentially carcinogenic properties. While there was no conclusive proof of the danger of the product, the company had not approved full evaluation of the ingredient. Besides the potential consumer impact of the sweetener, there were also concerns by Chief Food Technologist, Dr. Marie Mohit that the addition of the ingredient in the production process resulted in a chemical reaction which often affected the respiratory system of a number of workers. These issues did reach the ears of Hinds who was quite worker oriented. He engaged Dr. Mohit to undertake research on the issue. Generally, workers were not aware of the potential harm. They simply assumed that the respiratory issues were largely due to the general prevalence of savanna dust in the environment. Mohit was reluctant to directly research the issue since she had recently discovered that she was pregnant and felt that the material could negatively affect her unborn fetus. She therefore preferred to contract an external party to undertake the research. However, Hinds was adamant that involving an external party would potentially make the issue public and create challenges for the company. For now, he proposed that the workers could be provided with some surgical masks but not be advised of the danger. The decision of the CEO on the testing issue did not sit well with Mohit. She outright felt that she should not put herself in potential harm. For some time she considered her options and eventually determined that her best option would be to go above the CEO to the company Chairman, Mr. Dan Blake. Blake was often a visitor to various departments but never directly engaged staff on work activity. Nonetheless, he was seen as friendly and would pay compliments to staff as he passed by. Mohit decided that she would engage Blake one afternoon in the car park. In raising the issue with Blake, she provided documentation on the situation and was confident of getting a positive result. Mohit was pleased when Blake indicated that he would seriously consider the comments and suggestions. However, when he indicated that her proposal may be better considered over an evening of dinner and drinks, she became appalled. Mohit indicated that she would be unable to acquiesce, to which Blake calmly advised that she may have to therefore be prepared to do her job. Mohit made another attempt the next week and received a similar reaction. This time, Blake reminded Mohit that she should consider that her contract was up for renewal later in the year and her lack of social skills may be a determinant in the renewal. Mohit felt that she had exhausted her options and the company seemed to have no other mechanism to address the two challenges that were now before her.As Mohit sat at her desk one evening, she received an email from a reporter at the Daily Protector, a major national newspaper. The reporter indicated that there was an interest in speaking to her on some product issues. On reading the email, she began to wonder whether this email was another option for her to have the issues addressed.QUESTIONS1.a) Based on the case, are there any potentially harmful effects of the advertising done by Bubbly?b) Discuss the subject of the harmful nature of advertising and include other examples from the media to support your response. find the value of given expression=[tex]32 + 32 \div 32[/tex] pls help! will mark brainliest if correct
