A model of the ocean floor takes up 2/5 of the space in an aquarium. If 3/8 of the model is coral, what fraction of the space in an aquarium is taken up by coral?
Answer:
The fraction of space taken by coral is 3/20 in the aquarium.
Step-by-step explanation:
The fraction of space taken by coral is C=3/8of2/5 in the aquarium.
•C=3/8.2/5=6/40=3/20
The fraction of space taken by coral is 3/20 in the aquarium.

When Trudy planted a large bush in her garden, it was 2 feet tall. Now it is 50% taller. How tall is the bush now?
Answer: 3 feet tall
Step-by-step explanation:
50% of something is also 1/2 of it. So if we multiply 2 by 1/2 or .5, we get 1. So then we take 1 and add it to 2 because it is 50% taller than what it used to be.

Here are eight angles. Which of these angles are obtuse angles?
Enter your answer as a list of letters, separated by commas. For example, if you believe angles A, B, and F are obtuse, type A, B, F.
Help me please. Please, Please!!!
The obtuse angles from the given list are D (between 90° to 180°) and E (111° angle). Thus, the answer is D, E.
The angles are given as follows:
A: less than 45°
B: greater than 270°
C: right angle
D: between 90° to 180°
E: A 111° angle
F: A 222° angle
G: A 0.180° angle
H: A 180.180° angle
To identify which angles are obtuse, we need to determine the angles that are greater than 90 degrees but less than 180 degrees.
Among the given angles:
A: less than 45° (not obtuse)
B: greater than 270° (not obtuse)
C: right angle (not obtuse)
D: between 90° to 180° (obtuse)
E: 111° angle (obtuse)
F: 222° angle (not obtuse)
G: 0.180° angle (not obtuse)
H: 180.180° angle (not obtuse)
Therefore, the obtuse angles from the given list are:
D (between 90° to 180°)
E (111° angle)
The answer is D, E.

Graham recruited student volunteers to participate in his dissertation study. He set up several times for students to come to a specified classroom and read various types of instructional materials and to be tested. He ran all of his control conditions first and then for each session he placed all students at the session in the same treatment condition. This is problematic because those who volunteered early are likely different than those who volunteered later. This problem is primarily due to 1. response bias. 2. instrumentation bias. 3. researcher bias. 4. sampling bias.
Answer:
Sampling bias
Step-by-step explanation:
Bias refers a prominent problem in statistical analysis whereby one or more analytical factor are favored than the other during an analysis which should be made random. The problem. With Graham's dissertation study is the fact that he failed to randomlyvplace his subjects or observation in the study groups, favoring a particular group with non random subset. When randomization is ejected or missing from an analysis or study, it becomes less and less representative. Here, allotting early Arrivals Into the treatment group has introduced a sampling bias as those who came later, this will also leads to less reproducibility of experiment.

Classify the following triangle. Check all that apply. A. Scalene B. Right C. Acute D. Equilateral E. Obtuse F. Isosceles
Answer:
E and F
Step-by-step explanation:
The triangle given has two equal sides, and an obtuse angle that is more than 90° that measures 120°. The other two angles are of equal measure since their opposite sides are of the same length. Thus, this implies that it is an isosceles triangle because it has two equal base angles and two equal sides. It also implies that it is an obtuse triangle since one of it's angles is more than 90°.
Answer:
the correct answer is acute and scalene
