1/3=7/21, .. What are the means

Answer:

equal quantities something...

Step-by-step explanation:

Answer:

We have to find the LCM(least common multiple) of the two numbers.

24 is the LCM, because;

Multiples of 8 are -

8 x 1 = 8

8 x 2 = 16

8 x 3 = 24

Multiples of 12 are -

1 x 12 = 12

2 x 12 = 24

24 is their least common multiple.

Answer:

30

Step-by-step explanation:

Because 30 tens = 300

30 x 10 = 300

Answer:

x=3

Step-by-step explanation:

simplify

6x−8=3x+1

subtract 3x

3x−8=1

add 8 to each side

3x=9

divide both sides by 3

x=3

Answer:

x=5°

∠JIK=110°

Step-by-step explanation: From question,

20x-10+8x-20=140-6x

28x-30=140-6x

34x=170

x=170/34

x=5°

Eq. in ∠JIK,

140-30

=110°

Answer:

8/7 ÷ 4/1 = 7/32

Step-by-step explanation:

4/1 is the same as 4, flip all the Fractions so the bottom number is on the top and top on bottom and then multiply top x top and bottom x bottom

Hey there!

First, let's convert 4 into a fraction:

4=4/1

Now, divide the fractions:

[tex]\bold{\displaystyle\frac{8}{7} :\frac{4}{1}}[/tex]

Now, flop the second fraction over and multiply the first fraction times the second one:

[tex]\bold{\displaystyle\frac{8}{7} *\frac{1}{4}}[/tex]

Multiply the numerator (8) times the numerator of the second fraction (1) and multiply the denominator (7) times the denominator of the second fraction (4):

[tex]\bold{\displaystyle\frac{8}{28}}}[/tex]

Also, this fraction can be reduced:

[tex]\bold{\displaystyle\frac{4}{14}}[/tex]

We can divide by 2 again.

Hence, the answer is

[tex]\boxed{\boxed{\bold{\displaystyle\frac{2}{7}} }}}[/tex]

Hope everything is clear.

Let me know if you have any questions!

Answer:

$373.12

Step-by-step explanation:

You want to set this up with the equation for compound interest which is [tex]A=P(1+\frac{r}{n})}^{nt}[/tex]. A stands for amount, P stands for principle which in this case is 350, r is rate which for this one is .065, ad n is the amount of times compounded per year, and since it is compounded semi annually you do 2 for 2 times a year. Your equation based on this information should look like this:

[tex]A=350(1+\frac{.065}{2})}^{(2)(1)}[/tex]

After working this out you get A = 373.12

Answer:

Top Right

Step-by-step explanation:

If it's x≥1, you would plot a closed (or filled) circle at 1, and it would continue going right. If it's x<1, you would plot an open (or an o) circle with a line continuing left.

The function represents f(x)={3 if x<1x if x≥1 in Figure 4 is correct.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. There is no clear reason why the letter m is employed for slope, however its earliest use in English can be found in O'Brien (1844), who wrote the equation of the a straight line as "y = mx + b," and it can also found in Todhunter (1888), who wrote it as "y = mx + c." Slope is frequently denoted by the letter x. The ratio of the "vertical change" to the "horizontal change" between (any) two distinct points along a line is used to calculate slope. The ratio can also be written as a quotient ("rise over run"), which produces the same number for each and every two distinct points on a single line.

Here,

For x≥1 ⇒ f(x)=x

For x<1 ⇒ f(x)=3

Both these statements are followed together only in figure 4.

Hence, figure 4 is correct.

Answer:

the top two are acute triangles

the third(bottom left is an obtuse angle

and the last one(bottom right) is a right triangle

Step-by-step explanation:

the top angles are all under 90 degrees which is what makes them acute

the bottom left triangle has an angle greater than 90 which makes it obtuse

and the bottom right has a right angle, which makes it a right triangle

Answer:

3√(17) or 12.3693

Step-by-step explanation:

x^2 = 153

take square root from both side...

√(x^2) = √(153)

then...

x=√(153)

reduce to get...

x=3√(17)

the approximation is...

12.3693

Please rate!!

Answer:

x = 3sqroot17

x ~= 12.37

Step-by-step explanation:

To use the square root property, take the square root of both sides of the equation. see image.

Sqroot17 can be simplified in radical form or a decimal approximation.

For the radical form note that 153 is 9×17.

Since 9 is a perfect square, it simplifies a little bit. see image.

Answer:

-0.71

Step-by-step explanation:

Generally, a value of r greater than 0.7 is considered a strong correlation. Anything between 0.5 and 0.7 is a moderate correlation, and anything less than 0.4 is considered a weak or no correlation.

The r-value that represents the strongest correlation is -0.71.

Any of the many metrics used to describe the strength and direction of a linear relationship between two random variables is called a correlation coefficient.

So, r stands for the correlation coefficient.

Depending on the direction of the association, an r-value may be either negative or positive.

Yet, the link is greater the closer an r-value is to 1.

Here - 0.71 is closer to -1 then it is having a strongest correlation.

Answer:

Step-by-step explanation:

Both angles added together = 180 degrees. They both have a straight line as their base.

So let <ABC = x

Then <CBD = 3x      Add the two angles

x + 3x = 180              Combine

4x = 180                    Divide by 4

4x/4 = 180/4

x = 45

So 3x = 3*45 = 135

Complete Question

It is found that on average, 9% of the population recycles its garbage. Under this assumption, if a random sample of 120 households in Iowa City is taken, would you be surprised to find that fewer than 3% of households in the sample recycle their garbage? Use the fact that p-hat has an approximately normal distribution.

Group of answer choices

A I would not be surprised because there are lots of lazy students in Iowa City.

B I would not be surprised because 3% is not that far away from 9%.

C I would be surprised because Iowa City is a very clean community which means lots of people recycle their garbage.

D I would be surprised because if the 9% average is true, the chance of a sample proportion being less than 3% is very small (only 1%). Who cares? It's only garbage!

Answer:

The correct option is D

Step-by-step explanation:

From the question we are told that

    The sample size is  n  = 120

    The  mean of the proportion is  p =  0.09

Generally the standard deviation is mathematically represented as

      [tex]\sigma  =  \sqrt{\frac{p(1-p)}{n} }[/tex]

=>   [tex]\sigma  =  \sqrt{\frac{0.09(1-0.09)}{120 } }[/tex]

=>   [tex]\sigma  = 0.02612[/tex]

Generally the chance that fewer than 3%   of households in the sample recycle their garbage is mathematically represented as

    [tex]P(X < 0.03) =  P( \frac{X - p}{\sigma}  <  \frac{0.03 -0.09}{0.02612} )[/tex]

    [tex]P(X < 0.03) =  P( Z  < -2.297 )[/tex]

From the z-table  

     [tex]P( Z  < -2.297 ) = 0.01[/tex]

=> [tex]P(X < 0.03) = 0.01/tex]

=>   [tex]P(X < 0.03) = 1\% /tex]
