Answer:
Matched sample design
Step-by-step explanation:
- A matched subject design uses separate experimental groups for each particular treatment, ( A sample of brothers and sisters - genders ).
- But relies upon matching every subject in one group with an equivalent in another. (The differences in ratings between each brother and sister pair were compared. )
- The idea behind this is that it reduces the chances of an influential variable skewing the results by negating it.
Answer:
f(x) is neither even nor odd.
Step-by-step explanation:
For a function to be even f(x) = f(-x) and her results show that this is not the case.
For an odd function -f(x) = f(-x) so we test this:
-f(x) = -x^2 - 2x - 5 ; f(-x) = x^2 - 2x + 5 - so it is not odd.
16 it will be a positive number because it's the opposite of |-8| but it was -|8| then it would be a neg number
Answer:
D. 11655
Step-by-step explanation:
First find the 90th term:
a90=a1+(n−1)d
= -4+89(3)=263
Then find the sum:
Sn = n(a1 + an) / 2
S90 = 90 (-4 + 263) /2
S90 = 23,310/2
<u>S90 = 11,655</u>
The equation that represents the amount of soil, s in cubic centimeters the ferret can dig from the burrow in m minute is as follows:
s = 93m
One of the ferrets digs 465 cubic centimeters of soil from a burrow in 5 minutes.
The digging rate can be calculated as follows;
<h3>What is rate?</h3>
A rate is a ratio between two related quantities in different units. Therefore,
rate = 465 / 5 = 93 cubic centimetres per minutes.
Therefore, the equation that represents the amount of soil, s in cubic centimeters the ferret can dig from the burrow in m minute is as follows:
