cuál es el perímetro de los rectangulos que se presentan en la imagen​

Answer:

P-value = 0.0046  

Step-by-step explanation:

Given that:

Sample size n = 290

sample mean [tex]\overline{x_1}[/tex] = 4.1

standard deviation [tex]\sigma[/tex] = 0.6

population mean [tex]\mu[/tex] = 4.2

The null and the alternative hypothesis

[tex]\mathbf{H_o: \mu = 4.2} \\ \\ \mathbf{H_a: \mu \ne 4.2}[/tex]

This is a two-tailed test.

The test statistics can be computed as:

[tex]Z = \dfrac{\overline x - \mu }{\dfrac{\sigma}{\sqrt{n}}}[/tex]

[tex]Z = \dfrac{4.1 - 4.2 }{\dfrac{0.6}{\sqrt{290}}}[/tex]

[tex]Z = \dfrac{-0.1 }{\dfrac{0.6}{\sqrt{290}}}[/tex]

Z = -2.838

P-value = P(Z> 2.838)

P-value = P(Z< -2.838) +P(Z > 2.838)

P-value = 0.00227 + (1 - 0.9977)

P-value = 0.00457

P-value = 0.0046      (to 4 decimal places)

Answer:

48p2+4p-4

Step-by-step explanation:

Answer:

48p² +4p -4

Step-by-step explanation:

A polynomial of two terms is called a 'binomial'.

Here, we are multiplying 2 binomials.

This is so common, there is a standard way to do it. The method is called FOIL, which means "firsts, outsides, insides, then lasts"

You do it like this:

multiply the 'first terms' of each binomial                           -->  8p*6p = 48p²

multiply the 'outside' terms, far left and far right                 -->  8p*2 = 16p

multiply the 'inside' terms, the two terms in the 'middle'    -->  -2*6p = -12p

multiply the 'last' terms of each binomial                              -->  -2 * 2 = -4

Add 'like' terms: 48p² + (16p - 12p) -4

Answer --->  48p² +4p -4

Step-by-step explanation:

dollar amount of increase = $3.85 - $1.54 = $2.31

percentage increase = (amount of increase)/(original price) = $2.31/$1.54 = 1.5 = 150%

Answer:

The odds of rolling a 3 on a 6-sided number cube is 1 out of 6. The odds of rolling a 3 on either of two 6-sided cubes are 1/3. This is because 1/6 * 2 = 1/3. Therefore, an average of one-third of rolls will have a 3 in them. 1/3 expressed as a decimal is .3 repeating (.3333333 etc) and that rounds to 33 which is less than 34.

Answer:

The median is 5, mode is 5, and range is 12

Step-by-step explanation:

Answer:

MEDIAN - 5

MODE - 2 (4times)

RANGE - 13-1=12 (12 is the range)

Step-by-step explanation:

MEDIAN - Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

MODE - The mode is the element that occurs most in the data set. In this case, 2 occurs 4 times.

RANGE - Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is 13-1=12

Answer:

[tex]x\geq 4y\\y\leq \frac{x}{4}[/tex]

Answer:

$0.96

Step-by-step explanation:

You will pay $0.96 for a item with original price of $2.40 when discounted 60%. In this example, if you buy an item at $2.40 with 60% discount, you will pay 2.40 - 1.44 = 0.96 dollars.

Given:

The inequality is

[tex]3(q+6)>11[/tex]

To find:

The inequality that has the same solution set as the given inequality.

Solution:

We have,

[tex]3(q+6)>11[/tex]

Using distributive property, we get

[tex]3(q)+3(6)>11[/tex]

[tex]3q+18>11[/tex]

Since the given inequality can be rewritten as [tex]3q+18>11[/tex], therefore the inequality [tex]3q+18>11[/tex] has the same solution set as [tex]3(q+6)>11[/tex].

Hence, all options are incorrect. The required inequality is [tex]3q+18>11[/tex].

Answer:

13.5 and 7

Step-by-step explanation:

x + y = 20.5

x - y = 6.5

Hence,

x = 20.5 - y

20.5 - 2y = 6.5

Hence,

2y = 14

y = 7

and x = 20.5 - y = 20.5 - 7 = 13.5

The two numbers are are 13.5 and 7.

a + b = 20.5 equation 1

a  - b = 6.5 equation 2

Where a and b represents the two numbers

In order to determine the value of b, subtract equation 2 from 1

2b = 14

Divide both sides by 2

b = 7

Substitute for b in equation 1

a + 7 = 20.5

a = 20.5 - 7

a = 13.5

Answer:

Rounded to the nearest integer, at that time there were about 51,493,684 mortgages in the UK market.

Step-by-step explanation:

Given that in February 2019, 195,676 mortgages were outstanding in the UK, which represented 0.38% of all mortgages, to determine how many total mortgages were in the UK market at that time the following calculation must be performed:

0.38 = 195.676

100 = X

(100 x 195,676) / 0.38 = X

19,567,600 / 0.38 = X

51,493,684.21 = X

Thus, rounded to the nearest integer, at that time there were about 51,493,684 mortgages in the UK market.

Answer:

22 feet (if the distance is in feet, and the time in seconds)

Step-by-step explanation:

t = time

d = distance

To see if the mouse's distance is proportional to the time, you divide the distance with the time:

[tex]t_{3}[/tex] = 4

[tex]d_{3}[/tex] = 44

44 / 4 = 11

[tex]t_{4}[/tex] = 6

[tex]d_{4}[/tex] = 66

66 / 6 = 11 (the same as with 44 / 4. This means that the mouse distance and time is proportional)

Every second the mouse travels 11 feet.

And every other second the mouse travels 22 feet. (since (1, 11)*2 = (2, 22))

That may have been confusing, and if you have any questions, don't be afraid to ask them in the comments below!

Answer:

it is rational cause it can be turned into a fraction 0.7= 7/10

Answer:

The answer to your question is x = 4

x=4

Step-by-step explanation:

To start figuring this out, you need to combine like terms.

To start, you can combine all terms containing the variable x, which is 2x and 3x. This would then make the equation 5x+7-2=25.

You then need to combing the singular numbers, 7 and -2. Doing this brings the equation to 5x+5=25.

From here, subtract 5 from both sides to get you 5x=20.

Finally, you divide both sides by 5 to get you x=4.
