The method used to collect data for each scenario is observational study , secondary data , simulation .

<h3>What is Data Collection ?</h3>

The accumulation of data to perform research , experiment or any other study is called data collection

It is done by different methods.

While standing in front of the school, Jace recorded the number of students who walked, rode their bikes, took the bus, and were driven there. :

Because all feasible channels and techniques were investigated in order to get accurate data, this study is known as an observational study.

Noah conducted research to learn the data pertaining to the proportion of newborns having brown eyes. Since he didn't perform this directly, it is referred to as secondary data.

Lara repeatedly flipped two coins to see how many times two heads appeared because she knew she had a 25% chance of winning a contest. This is an example of simulation because she wanted to see if she would come up with the same outcome.

100 POINTS FOR BOTH SIDES PLZZZ Plzzz help me with this SIDES

Oliga [24]

Answer:

Step-by-step explanation:

point = (x, y)

A = ( $1\frac{1}{2}$ , 12)

B = ( $2\frac{1}{2}$ , 20)

C = (3, 24)

D = ( $3\frac{1}{2}$ , 28)

y/x ratios

$\frac{12}{1\frac{1}{2} }$

$\frac{20}{2\frac{1}{2} }$

24/3

$\frac{28}{3\frac{1}{2} }$

(1 2/3, 3 1/3) = 3 1/3 ÷ 1 2/3 = 2

(1 1/4, 2 1/2) = 2 1/2 ÷ 1 1/4 = 2

(3, 7) = 7 ÷ 3 = 2 1/3

(4 1/2, 9) = 9 ÷ 4 1/2 = 2

The ratio 7/3 (x = 3 and y = 7) is not proportionally related to the others.

The other ratios are equal to each other and are therefore in proportion.

7. yes

I WILL MARK BRAINLIEST PLEASE HELP !! Determine whether the two triangles are similar.

soldi70 [24.7K]

The two triangles are similar by SSA similarity. Option B is correct.

<h3>What is the triangle?</h3>

A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.

If the ratio of the sides are same as well as the one angle is common between the two triangles then in that condition there will be SSA similarity.

From the triangle ABC and DEC

The ratio of the sides is;

$\rm \frac{10}{12}= \frac{8}{9.6} \\\\ \frac{5}{6}= \frac{5}{6}$

One angle c is common in the two triangles.

The two triangles are similar by SSA similarity.

Hence, option B is correct.

Which of the following statements is TRUE about the stepwise selection procedure?

Rasek [7]

Answer:

A. The stepwise selection procedure uses Adjusted R-square as the "best" model criterion.

Step-by-step explanation:

Stepwise regression is a model which uses variables in step by step manner. The procedure involves removal or inclusion of independent variables one by one. It adds the most significant independent variable and removes the less significant independent variable. Usually stepwise selection uses R-square or Mallows Cp for picking the best fit.
