A study in which results are measured without intervention from the researcher is called a(n) Observational study. The correct option is B.

<h3>What is an Observational study?</h3>

An observational study draws conclusions from a sample of a population in disciplines like epidemiology, social sciences, psychology, and statistics when the independent variable is not under the researcher's control due to ethical considerations or practical limitations.

An observational study is a statistical investigation in which the researchers make no adjustments or interventions.

Therefore, the study in which results are measured without intervention from the researcher is called a(n) Observational study. The correct option is B.

An artist is painting flower pots that each require 1/32 gallon of paint. What is the maximum number of flower pots the artist c
Alex787 [66]

Answer:

24 flower pots

Step-by-step explanation:

Fraction of paint required per flower pot = 1/32

Number of pots that can be painted with 3/4 galoons of paint :

Total Fraction of paint had / fraction of paint required per flower pot

3/4 ÷ 1/32

3/4 * 32 / 1

(3*32) / 4

96 /4

= 24 flower pots

Complete the table below. If it is possible to work out the measure of the angle, write it down and show your method. If it is n
cestrela7 [59]

Answer:

w = 70°

x = 70°

y = 40°

z = 40°

Step-by-step explanation:

Notice that two sides of the figure are parallel to each other according to the arrow marking on both sides. This means that by definition this figure must be a parallelogram. This also means that the two other sides must be parallel as well so that there are also two sets of parallel sides.

There is also a transversal (line that cuts across two lines) of which are parallel, this forms different angles which are corresponding, alternate interior, alternate exterior, and supplementary.

70° at <BDC and w are alternate interior which means that they must be the same measure.

Therefore

w = 70°.

Since a parallelogram consists of 2 equal triangles, and we know that two angles are both 70° given that w is 70°, all interior angles must add up to 180° according to the triangle angle sum theorem. So 70° + 70° + y° = 180°.

140° + y° = 180°

–140° –140

Therefore

y = 40°.

Since angle x is exterior and adjacent of (next to) the two interior angles (70° and y), they are supplementary pairs which means that they add up to 180°, because they form a straight line.

Knowing that y is 40°,

x° + 40° + 70° = 180°.

x° + 110° = 180°

–110 –110

Therefore

x = 70°.

Now since angle z is alternate interior of angle y, alternate interior angles have the same measure by definition.

Given that we already know the measure of y = 40°. z must also be 40°

Therefore

z = 40°.

Estimate 843/84 by first rounding each number so that it has only 1 nonzero digit
mezya [45]

Answer:

10 is your answer.

Step-by-step explanation:

Both 843 and 84 will be turned to 800/80 because 4 is below 5 so it will be turned into a zero and the 8 left an 8.

800/80=10 is your answer.
