Answer:

After finding the money we were short with, we find that Option-b, that is, $2200 is the correct option.

Step-by-step explanation:

Given that the cost to repair the damaged car is $2700. We have $500.

Insurance company is a company that gives the payment of someone's valuable items when they are lost or get damaged. For example, home insurance, car insurance, life insurance and much more.

Here we can see that we are short with $2700 - $500 = $2200.

So, to complete the payment, insurance company will pay $2200.

Clearly, the correct option is Option-b.

8:45am + 2 hours = 10:45am

10:45am + 45 minutes = 11:30 am

Answer:

1.5 min

100 rotations

Step-by-step explanation:

to find 300 rotations time duration use the half-minute,

to find half of a minute divide the amount in one minute (200) by 2

200/2 = 100

then mutiply the 100 times 3 to find the time

100 * 3 = 300

therefore 30 sec (100 rot.) and 3 (3 times)

30 * 3 = 90

90 seconds minus 60 (one minute) is 30

so then it is equal to 1.5 minutes aka 1 min. 30 sec.

How long does it take to complete 300 rotations? 1.5 minutes (1 min. 30 sec.)

How many times does it rotate in a half minute?​ 100 rotations

Answer:

$324

Step-by-step explanation:

let x be the amount of money she had at first , then

[tex]\frac{1}{3}[/tex] x + [tex]\frac{1}{9}[/tex] x = 144 ( multiply through by 9 to clear the fractions )

The probability that exactly 4 are cured from 7 dolphins is 0.0128

Probability is the likeliness of an event to occur and it has a range of 0 to 1, where 0 means unlikely and 1 indicates certainty of the event to happen.

It is given that the 92% of all the dolphins are cured of an ear infection ,When treated with an antibiotic

If there are total dolphins given as 7

On the basis of given data

The dolphin that cannot be cured is given by

1 - p = 1 - (92/100) = 0.08 = 8/100

q = (8/100)
n= 7

r = 4

Therefore by Binomial Distribution

Putting the values

[tex]P = ^7C_4 (\dfrac{92}{100})^4 (\dfrac{8}{100})^{7-4}[/tex]

The proportion that can be used to represent the given statement is [tex]\frac{3}{1} =\frac{12}{4}[/tex]

Given that there are 3 feet in 1 yard, which is equivalent to 12 feet in 4 yards.

In general, the term "proportion" refers to a part, share, or amount that is compared to a whole. According to the definition of proportion, two ratios are in proportion when they are equal.

We need to determine the proportion that can be used to represent this.

Now, 1 yard = 3 feet implies  4 yards = 12 feet.

The required proportion can be written as [tex]\frac{3}{1} =\frac{12}{4}[/tex].

The probability will last longer than 2 years will be 3.3%.

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

First let us calculate the z score using the formula:

[tex]z = \dfrac{(x- \mu)} { s}[/tex]

where x = 2, u is the mean = 3.1 years, and s is the standard deviation

[tex]z =\dfrac{ (2 - 3.1) }{ 0.6}[/tex]

z = -1.83

Step-by-step explanation:

The cost of the item whose price $ 55 is $ 50.

The cost price is the price paid by an individual to buy an item or any other commodity. Or this can also be taken as the total amount of money spent by the manufacturer to assemble a product or deliver a service.

Here, Price equation in terms of cost

       P = C + C/10

      P =  (10C+C)/10

      P = 11C/10

108 = 60%

1% = 60%/60 = 108/60 = 1.8

100% = 1%×100 = 1.8×100 = 180

how many do not study French ?

the remainder of the students. that is 40% (100% - 60%) or 72 students (40×1.8 or simply 180-108).

Answer:

72 students do not study French.

Step-by-step explanation:

60% = 108 students

1. 108 ÷ 60 = 1.8 ( this is to find 1% of the students)

2. 1.8(1%) × 40 = 72

To check the answer:

108 + 72 = 180

1600 children and 1400 adults attended

Let the children be x and adult be y.

So, we have the following equations:

x + y = 3000

1.5x + 5y = 9400

Make x the subject in x + y = 3000

x = 3000 - y

Substitute x = 3000 - y  in 1.5x + 5y = 9400

1.5(3000 - y) + 5y = 9400

Expand

4500 - 1.5y + 5y = 9400

Evaluate the like terms

3.5y = 4900

Divide both sides by 3.5

y = 1400

Substitute y = 1400 in x = 3000 - y

x = 3000 - 1400

Evaluate

x = 1600

Hence, 1600 children and 1400 adults attended

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

Answer: pi/3

Step-by-step explanation:

All of the other answers are asymptotes of the function, which by definition means they are not included in the domain, because they are undefined in the domain at that point. If you graph the function and graph all of those x values, you will see that (pi/3) is the only line that crosses the function.

Also, I took the test and got it right.

Only the value of x , [tex]\frac{\pi }{3}[/tex] is in the domain of the function.

The domain of a function is the set of values that we are allowed to plug into our function which makes the function defined.

The trigonometric functions are also called the angle functions, which relates the angles and the ratios of the sides of a right angle triangle.

According to the given question.

We have a trigonomtery function.

[tex]f(x) = 4cot(2x)+3[/tex]

The above trigonometry function can be written as

[tex]f(x) = 4\frac{cos(2x)}{sin(2x)} + 3[/tex]

For the function to be defined the denominator can't be zero.

[tex]sin(2x) \neq 2n\pi ( n \in0, 1, 2, 3, ..)[/tex]

Therefore, from the given values for the x we can only put [tex]\frac{\pi }{3}[/tex] in the given function because [tex]\frac{\pi }{2}[/tex] makes the denominator o which makes the function undefined. Similarly for the π also.

Hence, only the value of x , [tex]\frac{\pi }{3}[/tex] is in the domain of the function.
