Answer:
Conclusion: The statement is true.
Step-by-step explanation:
A longitudinal design consists of the observation of one or several variables in a group of individuals during a time window, in order to record the possible changes that are generated in said characteristic in that lapse.
On the other hand, the transverse design is concerned with measuring one or several variables at a single point of time and, therefore, does not allow changes to be detected over time.
Conclusion: The statement is true.
Answer: -16n-41
Step-by-step explanation:
first, distribute 2 through the parentheses:
<u>2(-n-3)</u>-7(5+2n) = <u>-2n-6</u>-7(5+2n)
second, distribute 7 through the parenthesis:
-2n-6<u>-7(5+2n) </u>= -2n-6<u>-35-14n</u>
Collect like terms:
<u>-2n</u>-6-35 and <u>-16n</u>-6-35
Calculate the difference:
-2n<u>-6-35</u>-14n = -16n-<u>41</u>
SOLUTION:
<u>-16n-41</u>
Part A: They are 2 1/4 inches apart on the map.
Part B: They are 13 miles apart.
Answer:
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z----> the scale factor
x----> volume of the larger solid
y----> volume of the smaller solid
we have
substitute
step 2
Find the surface area of the larger solid
we know that
If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared
Let
z----> the scale factor
x----> surface area of the larger solid
y----> surface area of the smaller solid
we have
substitute
