Answer:

Its divide and 4

Step-by-step explanation:

To find the values in each row divide the values in previous row by 4.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Clearly, from observation,
Each column represent geometric progression with common ratio r = 1/4. So when moving downward, the element in the rows decreases as multiple of 1/4.
Here,
R(1, 1) = 256
R (2 ,1) = 64
R(2,1)/R(1,1)=1/4

Thus, To find the values in each row divide the values in previous row by 4.

i got 100 0n the quiz

Answer:

Step-by-step explanation:

∠E = ∠G

∠D= ∠F because it’s a parallelogram ==> D=F=2x+12 and E=G=5x

5x+2x+12=180

7x=168

X=24

Solution 2:

2*5x+2*(2x+12)=360

10x+4x+24=360

14x=360-24=336

X=336/14

X=24

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.

Step-by-step explanation:

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:

$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:

The train would travel 30km in 30 minutes.

Step-by-step explanation:

Speed of train = 60km/hr

30 minutes = I hour ÷ 2

If 30 minutes is equal to half an hour, and it takes an hour for the train to travel 60 km, then you would have to half 60 km to find the length travelled in 30 minutes.

Equation: 60km ÷ 2 = 30km

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.

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.

Step-by-step explanation:

The correct answer for the average salinity of the estuary would be 22.235.

Given in the question,

Salinity of ocean water at the entrance to the estuary:  35.

Volume of ocean water in the estuary:  63% (or 0.63).

Volume of freshwater in the estuary:  37% (or 0.37).

Consider, salinity of freshwater as 0.5.

To calculate the average salinity of the estuary, the  formula know is:

Average Salinity = (Salinity of Ocean Water * Volume of Ocean Water + Salinity of Freshwater * Volume of Freshwater) / Total Volume of Estuary

[tex]= \dfrac{35*0.63 + 0.5 * 0.37}{1}\\\\= 22.05 + 0.185\\\\= 22.235[/tex]

Therefore, Average salinity of the estuary would be approximately 22.235.

Answer:

Assuming the cones are the same height, then

V1 = pi * r^2 * h/3 = 3.14159*1^2*h/3

V2 = 3.14159*2.5^2*h/3 = 3.14159*6.25*h/3

V1/V2=(3.14159*h/3)/(3.14159*6.25)*h/3

V1/V2 = 1/6.25 = .16

V2/V1=(3.14159*6.25)*h/3/(3.14159*h/3)

V2/V1=6.25/1 = 6.25
