The equation of motion of a body thrown vertically upwards:
,
Substitute in formula (1) the value t=2 c:
48 i think I don’t nun of this that I why I got it to get answers not give them smh
Answer:
{Rounded to the nearest Hundredths place}
1) Mercury= 170.55
2) Venus= 277.86
3) Earth= 389.62
4) Mars= 401.29
Explanation:
Mercury: 3.3022 x 10^19= 170.549894825 which rounds to 170.55
Earth: 5.9722 x 10^24= 389.618945662 which rounds to 389.62
Venus: 4.8675 x 10^21= 277.855972801 which rounds to 277.86
Mars: 6.4185 x 10^23= 401.287714067 which rounds to 401.29
•So smallest to largest would be• 170.55, 277.86, 389.62, and 401.29
[I hope this helps][Sorry if it doesn’t make sense]
Answer:
20%
Step-by-step explanation:
There is a 20% chance you get selected for researching China because 5 out of 25 spaces are ones for researching China.
To solve the problem we must know about the correlation coefficients.
<h3>What is the correlation coefficient?</h3>
The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
- 1 indicates a strong positive relationship.
- -1 indicates a strong negative relationship.
- A result of zero indicates no relationship at all, therefore, independent variable.
The correlation coefficient 0.2 denotes, "There is a weak positive relationship between the size of a student's home and the student's age".
Given to us
- The correlation coefficient for the data is 0.2.
As we can see that the value of the correlation coefficient is 0.2, therefore, it is far from1 meaning the relationship is weak, while the '+' symbol denotes that the relationship is positive.
Hence, the correlation coefficient 0.2 denotes, "There is a weak positive relationship between the size of a student's home and the student's age".
