She must have a score greater than 69 in her final tests

Let the required score be "x"

The mean of the data is the ratio of the sum to the total sample

Mean = 80+76+85+85+x/5

80+76+85+85+2x/5 > 79

326+x/5 > 79

326 + x > 395

x > 395 - 326

x > 69

This shows that she must have a score greater than 69 in her final tests

Use distance formula d=√(X2 – X1 )2 + (X2 – X1 )2, calculate the distance r from the origin to the point r (-2, √5).

lesya692 [45]

$d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}} \\d = \sqrt{(\sqrt{5} - (-2))^{2} + (\sqrt{5} - (-2))^{2}} \\d = \sqrt{(\sqrt{5} + 2)^{2} + (\sqrt{5} + 2)^{2}} \\d = \sqrt{(4 + 4\sqrt{5} + 5) + (4v + 4\sqrt{5} + 5)} \\d = \sqrt{0 + 0} \\d = \sqrt{0} \\d = 0$
