Answer:

a. Apparent correlations between two or more variables can stimulate investigation and present possible solutions to be explored.

Step-by-step explanation:

Correlation is a scenario, where an action X causes another action Y to occur, but one of the actions does not really need to affect the other's occurrence. Correlation occurs because of the tendency of people to seek the relationship between events. The fact that two events are happening at the same time does not necessarily imply a cause and effect relationship, although there might be a possibility of such.

Correlation is used in scientific studies to draw the relationship between two events, but it does not stop at that. Through investigation has to be made to confirm that there is indeed a correlation.

A maritime flag is shown. What is the area of the shaded part of the flag? Explain
Rom4ik [11]

Answer:

<em></em>Area = 72in^2<em></em>

<em></em>

Step-by-step explanation:

<em>Your question is incomplete without an attachment (See attachment)</em>

Required

Determine the area of the shaded part

From the attachment;

<em>Assume that the shaded portion is closed to the right;</em>

<em>Calculate  the Area:</em>

<em></em>Area_1 = Length * Width<em></em>

<em></em>Area_2 = 8in * (6in + 6in)<em></em>

<em></em>Area_2 = 8in * 12in<em></em>

<em></em>Area_1 = 96in^2<em></em>

<em></em>

<em>Next;</em>

<em>Calculate the Area of the imaginary triangle (on the right)</em>

<em></em>Area_2 = \frac{1}{2} * base * height<em></em>

<em></em>Area_2 = \frac{1}{2} * (6in + 6in) * 4in<em></em>

<em></em>Area_2 = \frac{1}{2} * 12in * 4in<em></em>

<em></em>Area_2 = \frac{1}{2} * 48in^2<em></em>

<em></em>Area_2 = 24in^2<em></em>

<em></em>

<em>Lastly, calculate the Area of the Shaded Part</em>

<em></em>Area = Area_1 - Area_2<em></em>

<em></em>Area = 96in^2 - 24in^2<em></em>

<em></em>Area = 72in^2<em></em>

<em></em>

<em>Hence,</em>

<em>The area of the shaded part is 72in²</em>

Which souvenirs cost less than $2.25 per item?
strojnjashka [21]
Hello! To find the answer to these problems, we need to divide the price by the quantity bought. For example, if you buy 4 erasers for $2, you would do 2/4 to find the cost per eraser. When you divide all of the items correct, these are the unit prices you get:

tote bags: $1.96
picture frames: $2.15
water bottles: $2.30
mugs: $1.99
t-shirts: $2.50

Okay. So we are looking for the souvenirs that cost less than $2.25. 1.96, 2.15, and 1.99 are all less than 2.25, while 2.3 and 2.5 are more than 2.25. Therefore, tote bags, picture frames, and mugs are the souvenirs that cost less than $2.25.

I need help with this problem
Dmitriy789 [7]

Answer:

<h2>h = 15</h2>

Step-by-step explanation:

The formula of an area of a parallelogram:

A=bh

b - side

h - height

We have b₁ = 18 and h₁ 10 and b₂ = 12.

b_1h_1=b_2h

Substitute:

12h=(18)(10)

12h=180            <em>divide both sides by 12</em>

h=15
