Find the distance between the points (7,23) and (3,-3), rounded to the hundredths place

Molodets [167]

Answer:

26.31

Step-by-step explanation:

Use distance formula

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

substitute in points and solve

d = $\sqrt{(7-3)^2 + (23-(-3))^{2} }$

d = $\sqrt{4^{2}+26^{2} }$

d = $\sqrt{16 + 676}$

d = $\sqrt{692}$

d = 26.30589288

d = 26.31 rounded

Given a mean of 24.5 and a standard deviation of 1.7 what is the z score of the value 24 rounded to the nearest tenth?

Softa [21]

The correct answer is B) -0.3

Z-scores are found using the formula

z = (X-μ)/σ

For this problem, we have

z = (24-24.5)/1.7 = -0.5/1.7 = -0.3
