Answer:
455m
Step-by-step explanation:
We know that acceleration is acceleration due to gravity, which is 10m/s, and initial speed u=0m/s
Use the motion equation to find distance when t=10:
d=ut+(1/2)at²
d=0t+(1/2)(10)(10²)
d=500m
The distance travelled in the seven seconds following the first three = 500-45=455m
Answer:
84 is the highest possible course average
Step-by-step explanation:
Total number of examinations = 5
Average = sum of scores in each examination/total number of examinations
Let the score for the last examination be x.
Average = (66+78+94+83+x)/5 = y
5y = 321+x
x = 5y -321
If y = 6, x = 5×6 -321 =-291.the student cannot score -291
If y = 80, x = 5×80 -321 =79.he can still score higher
If If y = 84, x = 5×84 -321 =99.This would be the highest possible course average after the last examination.
If y= 100
The average cannot be 100 as student cannot score 179(maximum score is 100)
Answer:
0.749m and 2.25m
Step-by-step explanation:
to convert from centimeters to meters, you divide by 100 because there are 100cm in 1m
74.9cm/100= 0.749m and 225cm/100=2.25m
Answer:
multiple regression
Step-by-step explanation:
In the field of statistics, the multiple regression is the statistical technique which uses the various explanatory variables for predicting the outcome of the response variable. It is the extension of the simple linear regression. It explains the relation between the multiple predictor variables or independent variables and one dependent variable or criterion variable.
In the context, the manager of a tourist company predicting the number of calls to the toll free number is using the statistical technique of multiple regression.
