Answer:
s=6
Step-by-step explanation:
s= 10(1/2)+ -2(1/2)^2
s= 5+ (-1)^2
s= 5+1
s=6
Answer:
0.88 (I think this is how Mrs. Futch wants it to be written)
Step-by-step explanation:
h=-16t^2+14t
(Substitute h with 0)
0=-16t^2+14t
(Factor)
0=2t(-8t+7)
2t=0 -8t+7=0
t=0 t=0.88
{0, 0.88}
Answer:
The study provided uses a Cluster sampling method.
Step-by-step explanation:
The researcher first selects all the schools in the district.
Then he samples 5 schools from the entire district using a random number generator.
Then the researcher interviews every teacher from the 5 schools selected.
This is an example of cluster sampling.
In a Cluster sampling method, the researchers first divide the entire population into homogeneous groups, then selects a random sample of groups form the population. Then they select a random sample from each group selected.
If the researcher samples the entire groups selected then this is the case of one-stage cluster sampling and if they select a random sample of fixed size from each group selected then this a case of two-stage sampling.
Thus, the study provided uses a Cluster sampling method.
Answer:
C. The cheetah runs 24.5 meters per second & D. The cheetah will run 1,470 meters in 1 minute
Step-by-step explanation:
First I did 196/8 to see how many meters the cheetah ran per second which got me 24.5 meters, so that simply gave me answer C. I then did process of elimination through the answers by taking 24.5 and multiplying it by however may seconds to see if it got the same distance that was in the answer. When I came to D. I had to do 24.5*60 (Because one minute is 60 seconds) which got that answer.
