Doroteo determined that the correlation coefficient for a set of data was -.9 what percent of the total variation in the Y values is not explained by the regression line

Answer:

x is 60°

y is 30°

(would really, reallly appreciate the brainliest)

Step-by-step explanation:

x can be seen as what's needed to do a full 180 ° turn when you already turned 120°

y is 60° bc the sum of all tree angles of a triangle is always 180°

90° are given with the little square, 60 by the similar reasoning as above

Answer:

Step-by-step explanation:

L an M are parallel & P is transversal.

So, 120, x are co-interior angles, ie 180

x +120 = 180

x = 180 - 120

x = 60

The angle  vertically opposite to x, will have the same value of x.

Vertically opposite angles are equal

In triangle, sum of angles = 180

60 + 90 + y = 180

150 + y =180

y =180 -  150

y =30

Answer:

( About ) 90%

Step-by-step explanation:

We are given the table below;

Number of seconds | Amount of water

              0                 |             0

              3                 |             75

              6                 |             150

Now from this table we see that the rate change is that for every 3 seconds of difference, the amount of water increases by 75 cm^3;

If that is so, the amount of water after 7 seconds is 150 + ( 75 / 3 ), provided the difference in seconds between 6 and 7 is 1 / 3rd that of the difference between 0 and 3, or 3 and 6;

150 + ( 75 / 3 ),

150 + 25,

175 cm^3

Now let us compute the total volume of this cylinder, as such;

πr^2 * height,

π * ( 3 )^2 * 7,

9 * π * 7,

Volume of can ⇒ 197.82 cm^3

175 / 197.82 = 0.9 = Solution; 90%

Answer:

The diameter of the ride is 44 feets.

Step-by-step explanation:

We have,

The circumference of the frame is about 138 ft.

It is required to find the diameter of the ride.

The circumference of means that the outer covering of the circle. It is given by the formula as follows:

[tex]C=2\pi r[/tex]

r is radius

Since, 2r = d, diameter of circle

[tex]C=d\pi \\\\d=\dfrac{C}{\pi}\\\\d=\dfrac{138}{3.14}\\\\d=43.94\ ft[/tex]

or

d = 44 feets

So, the diameter of the ride is 44 feets.

Answer:

Prt A- Yes

Part B- 5:1

Step-by-step explanation:

The ratios in cases 1 and 2 form a proportion. This can be seen by dividing case a by 5 which gives 4:3;

i.e 20:15 = 20

                15

If you divide both numerator and denominator by 5, we have 4/3.

This shows that case 1 and 2 have the same proportions of friends to strangers.

Part B.

The number of friends in case 1 is 20 while in case 2 is 4.

we have, 20:4

= 20

   4

Dividing each by 4, we have 5:1.

This means that the ratio of friends that in case 1 to case 2 is 5:1.

Answer:

[tex]\dfrac{3}{10}[/tex]

Step-by-step explanation:

Length of an arc[tex]=\dfrac{\theta}{2\pi}X 2\pi r=\theta r[/tex]

If the central angle of the arc is [tex]\dfrac{3\pi}{5}[/tex]

Length of an arc[tex]=\dfrac{3\pi r}{5}[/tex]

Therefore:

Ratio of the length of the arc to the circumference

[tex]=\dfrac{3\pi r}{5}:2\pi r\\=\dfrac{3\pi r}{5*2\pi r}\\=\dfrac{3}{10}[/tex]

Therefore, the arc is [tex]\dfrac{3}{10}[/tex] of the circumference is this arc.

Answer:

7/11

Step-by-step explanation:

There are 11 numbers with only 7 numbers with a multiple of 5.

Answer:

7/11

Step-by-step explanation:

first, you must determine which numbers are multiples of five. multiples of five are numbers 5 or greater that end in 0 or 5. for example, 5,10,15,20,25... . from this list, you can tell that 7 of these numbers are multiples of 5 : 55,30,50,40,40,45,25 . Next, you count the total amount of numbers. there are 11 numbers in the list. so, the probability of randomly choosing a multiple of 5 is 7/11 :)

Answer:

It depends on what shape your talking about, like: a rectangle - Length  multiplied by Width

Step-by-step explanation:

Hope this helped, plz mark as brainiest :)

Answer:

Number of rectangles  could alex draw with an area of 11cm² = 1

Step-by-step explanation:

Minimum length in centimeter grid = 1 cm

Alex is drawing rectangles with different areas on a centimetre grid.He can draw 3 different rectangles with an area of 12cm²

That is

                  [tex]12 = 1 \times12\\\\12=2\times6\\\\12=3 \times4[/tex]

         These are the 3 different rectangles with an area of 12cm².

Now we need to find how many rectangles could alex draw with an area of 11cm².

                    11 = 1 x 11

So only one factorization is possible.

Number of rectangles  could alex draw with an area of 11cm² = 1

Answer:

Alex can only drawn 1 rectangle with an area of 11 cm²

Step-by-step explanation:

When Area = 12 cm², Alex could draw 3 rectangles.

This is because, Area of a rectangle = Length * Breadth

and the factors of 12 are 1, 2, 3, 4, 6, and 12.

The 3 triangle formed can be gotten from the correct combinations of these factors, which are 12 × 1, 2 × 6, 3 × 4.

All of these three combinations give us an area of 12 cm²

Similarly when Area = 11 cm², 11 is a prime number and its factors are 1 and 11.

The only combination that can be made from these factors is 11 × 1.

This means that only one rectangle can be drawn

Answer:

14.13

Step-by-step explanation:

Step 1) Find the total area

A = pi x r^2

A = pi x 3^2

A = 9pi

Step 2) Divide the total area by 4

9pi / 4 = 2.25pi

2.25pi = 7.07

A = 7.07 square feet

Answer:

3.1, 3.2, 3.3

Step-by-step explanation:

There are infinite options but a rational number is a fraction, decimal, or repeating decimal.

3 [tex]\frac{1}{3}[/tex] is an example of a fraction between 3 and 4

3.2 is an example of a decimal between 3 and 4

3.3333333... is an example of a repeating decimal between 3 and 4

Answer: 3.2526252625...

Explanation: The number above would be a rational number because it's a repeating decimal. Notice that in the decimal above, 2526 is a group of repeating digits and repeating decimals are rational.
