Since a sample data shows that a linear correlation coefficient between two variables is about 0.08, then it rules out a possibl

e causal relationship between the two variables.
Mathematics

myrzilka [38]3 years ago

Answer:

False

Explanation:

A linear correlation coefficient is used to measure the the level of relationship between two seemingly dependent and independent variables. A relationship exists between two variables in linear correlation if one affects the other, either negatively or positively never zero. If linear correlation has a negative value then one variable increases while the other decreases. If linear correlation coefficient is positive then both variables increase together. If zero then there is no relationship as one variable's increase or decrease has nothing to do with the other. In the case above, correlation is positive at 0.08 hence we can say that there is a relationship between the two variables.

Lila sells wedges of cheese at the local farmers' market. To make the wedges, she cuts a big 5-pound block of cheese into 16 pie
Anestetic [448]

Answer:

Hence the each cheese piece weight equal to 0.3125 pounds

Step-by-step explanation:

Given;

5 pound of cheese block cut down into 16 pieces

To Find:

How much does each wedge of each cheese weigh

Solution:

Now each cheese weigh as follows:

<em>16 cheese pieces of ideal size are considered here so</em>

<em>16 piece equally contribute the the total weight of 5 pounds.</em>

So 5 pound in divided into 16 pieces

i.e 5/16=0.3125 pound per pieces

Hence the each cheese piece weight equal to 0.3125 pounds

i.e Each cheese piece is about 6.25 % of total weight  i.e (6.25*16=100 %)

By AAS congruence theorem, ΔABD is congruent ΔCDB.

Quadrilateral ABCD is given in the figure.

<h3>What is the congruence theorem?</h3>

Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.

Given, AB║DC

Consider ΔABD and ΔCDB

m∠A=m∠C=90° (Given)

m∠ABD=m∠BDC (Alternate interior angles)

BD = BD (Common)

Using AAS congruence theorem, ΔABD ≅ ΔCDB

Hence, by AAS congruence theorem, ΔABD is congruent ΔCDB.

The sector shows the area of a lawn that will be watered by a sprinkler. What is the area, rounded to the nearest tenth? Use 3.1
a_sh-v [17]

Answer:

95.5\ ft^2

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

A circumference of the circle subtends a central angle of 360 degrees

so

using proportion

\frac{2\pi r }{360^o}=\frac{10}{30^o} \\\\r=\frac{360(10)}{2(3.14)(30)}\\\\r= 19.1\ ft

step 2

Find the area of sector

we know that

The area of the circle subtends a central angle of 360 degrees

so using proportion

Let

x ----> the area of the sector

\frac{\pi r^{2}}{360^o}=\frac{x}{30^o}\\\\x=\frac{3.14(19.1^2)(30)}{360}\\\\x=95.5\ ft^2
