Answer:
<u>Mika estimated the sum to be 216; the actual sum is 216.27.</u>
Step-by-step explanation:
Let's find the rounded sum and the actual sum, as follows:
Rounding each number to the nearest whole:
189.27 ⇒ 189
15.8 ⇒ 16
11.2 ⇒ 11
Sum = 189 + 16 + 11
Sum = 216
Actual sum:
Actual sum = 189.27 + 15.8 + 11.2
Actual sum = 216.27
<u>Mika estimated the sum to be 216; the actual sum is 216.27.</u>
The answer is 5/9. I showed a bit more work on the other post

Step-by-step explanation:
1/4 of 16 is 4
Answer:
Step-by-step explanation:
It is not perfectly linear because the difference between the y values is not constant. However, when you use the regression function on your calculator and enter the L1 values as your x's and the L2 values as your y's and use the LinReg equation, you get an r-squared value of .999900 and an r value of .999950. So it linear, with your answer being "linear, because the r value for the linear model is closest to 1".
Gravitational force:
F = G * m1 * m2 / r²
And gravitational constant: G = 6.67 * 10^(-11) m³/kgs²
Therefore:
r = sqrt ( G * m1 * m2 / F ) =
= sqrt ( 6.67 * 10^(-11) m³/kgs² * 1.3 * 10^(22) kg * 1.6 * 10^(21) / 3.61 * 10^(18) N ) =
= sqrt ( 3.84 * 10^(14) ) = 1.96 * 10^(7) m ≈ 2 * 10^(7) m
Answer:
A ) 2.0 * 10^(7) m
