no correlation

positive correlation

negative correlation

Answers

Answer:

Seems to be no correlation at all.

Answer:

anges between -1 and +1 and quantifies the direction and strength of the linear association between the two variables. The correlation between two variables can be positive (i.e., higher levels of one variable are associated with higher levels of the other) or negative (i.e., higher levels of one variable are associated with lower levels of the other).

The sign of the correlation coefficient indicates the direction of the association. The magnitude of the correlation coefficient indicates the strength of the association.

For example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association. A correlation close to zero suggests no linear association between two continuous variables.

It is important to note that there may be a non-linear association between two continuous variables, but computation of a correlation coefficient does not detect this. Therefore, it is always important to evaluate the data carefully before computing a correlation coefficient. Graphical displays are particularly useful to explore associations between variables.

The figure below shows four hypothetical scenarios in which one continuous variable is plotted along the X-axis and the other along the Y-axis.

What two numbers multiply to +34 and add to -19

Answers

Answer:

17 * 2 = 34

-10 + (-9) = -19 or -29 + 10 = -19

Step-by-step explanation:

For the first question, divide 34 * 2 and you get 17, DOUBLE CHECK YOUR ANSWER!

17*2 = 34 ✔

For the second, mess around with a few numbers add +10 and -29,  COUNT DOWN from 10 and -29.

since + + + = + then - + - = -

Write the equation of the line in Slope-Intercept form.

Answers

Answer:

Y=-2/3+4

Step-by-step explanation:

The slope of the equation can be solved with

2-4/3-0 y2-y1 divide by x2-x1 which gives 3/2 and the y intercept the point at which the slope hits the y intercept which is 4. Also the slope is negative as it’s pointed downwards.

Getting the slope:

m=[tex](y_1 - y_2 )/(x_1 - x_2)[/tex]

Using this formula, the slope is calculated to be -2/3

To find intercept, plug in a point value into equation and solve.

Intercept = 4

Total equation: y=-2/3x + 4

Answers

Answer:

The surface area of the shape is 292 in^2

Step-by-step explanation:

Here, we want to find the surface area of the cuboidal shape

Mathematically, the area of a cuboid can be calculated using the formula;

A = 2(lb + lh + bh)

where l is the length which is 7 inches

b is the breadth which is 6 cm

h is the height which is 8 cm

Substituting these values, we have

A = 2((8 * 6) + (7 * 6) + (8 * 7))

A = 2(56 + 42 + 48)

A = 2 * 146

A = 292 in^2

The area of the parallelogram will be 98 square feet.

What is a parallelogram?

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.

Let h be the perpendicular distance between the parallel side and b be the length of the base of the rectangle.

Then the area of the parallelogram will be given as,

Area of parallelogram = b x h

The length of the base of the parallelogram is 14 feet, and the value of h is 7 feet.

Then the area of the parallelogram will be

Area pf parallelogram = 14 x 7

Area pf parallelogram = 98 square feet

Then the area of the parallelogram will be 98 square feet.

Answers

If a number has a decimal point , then the first digit to the right of the decimal point indicates the number of tenths. The second digit to the right of the decimal point indicates the number of hundredths.  

In this case the .3 indicates 3/10ths of a kilogram.  or 300 grams!

In the other case 0.03 indicates 3/100ths of a kilogram or 30 grams!

So, to compare the two:

the tenths decimal is 10 times bigger than the decimal in the next spot (hundredths)
