Answer:
approx 10.25
Step-by-step explanation:
According to Euclid theorem :
EG^2= DG*FG= 16*5=80
From right triangle EDG according to Phitagor's theorem:
DE^2=EG^2+DG^2= 80+25=105
DE=sqrt(105)= approx 10.25
Answer:
-15°C.
Step-by-step explanation:
They tell us that the temperature dropped 3 ° C every hour, therefore, the temperature change every hour = -3 ° C
They also tell us the total number of hours during which the temperature was changed = 5,
We have to:
The total change in temperature = change over an hour * total number of hours:
TC = - 3rd * 5
TC = -15 °
Then we can affirm that the integer representing the temperature change is -15 ° C.
Answer:
45
Step-by-step explanation:
negative times negative equals positive
Correlation coefficient is the numerical representation of how one variable predicts the change of the other. In this case, if the AP tests scores and the SAT scores have 0.93 correlation coefficient, this means that the two results move in the same direction. When AP test results go up, then we can say that SAT scores will go up too, same also if one goes down, so does the other.
