Answer: A = k =250
B= y,x=0.5
Step-by-step explanation: Find the constant of variation.
Answer:
AB = 8
AD = 10
<A = 118
<D = 62
Step-by-step explanation:
1. AB
Because opposite sides in a parallelogram are equal, DC = AB = 8.
2. AD
Because opposite sides in a parallelogram are equal, BC = AD = 10.
3. <A
Adjacent angles are supplementary in a parallelogram, so A = 180 - 62 = 118
4. <D
Opposite angles are equal in a parallelogram, so B = D = 62
Mean = when the data is continuous and symmetrical.
median = can determine a approximate average.
mode = to find the most common average or set of data.

Answer:
Step-by-step explanation:
Hello!
The study hypothesis was that playing videogames improves the reaction time on elderly individuals. If so, then the average reaction time on the elderly that played videogames is less than the average reaction time of elderly that do not play video games.
In the null hypothesis, the researchers usually state the known information or the possibility that the experiment has no effect, in this case, that playing video games doesn't modify the average reaction time in the elderly. If this hypothesis was rejected, this means that playing videogames increases significantly the reflexes in elderly individuals and reduces their reaction time.
I hope it helps!
Answer:
24 in
Step-by-step explanation:
Compare "like" things:
Big/small = Big/small
30/L = 10/8
Crossmultiply
240 = 10L
Divide by 10
240/10 = 10L/10
24 = L
