Answer:
a certain number that i do not know
Step-by-step explanation:
Answer:
40 km^2
16 cm^2
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
Actual area = scale factor x scaled area
8 x 5 = 40 km^2
Scaled area on the map = 128.8 = 16 cm^2
Answer:
75%
Step-by-step explanation:
18 divided by 24 equals 0.75 and then you multiply that by 100 and you get 75 so its 75%
We have 4 parts in one whole when we split it into fourths; in other words, 4/4 = 1 whole. To convert 10/4 to a mixed number, we first need to find out how many wholes can fit into it. In this case, we can break 10/4 down into
Giving us <em>2 wholes </em>and <em>2 fourths</em>, or 2 2/4 as a mixed number. Note that 2/4 is the same as 1/2, so we can write the simplified mixed number as
2 1/2
For this case we have different effectiveness using two conditions the first one with to students who chose the professor as the chair of their doctoral committe and the second is associated to all students and we see a different effectiveness
This is a clear example of an error in the A)Data Gathering Phase
And the reason is because they introduce bias in the study just selecting students who select the professor as the chair of their doctoral committee, and it's very evident when they select all the students the real results change
