The number of adult Americans from a random sample of n adults who support a bill proposing to extend daylight savings time is a
GalinKa [24]

Answer:

Right of X = 635.5

Step-by-step explanation:

By using the normal approximation to the Binomial random variable, we usually make use of continuity correction.

According to the rule of continuity;

P(X ≤ k) becomes  P( X ≤ K + 0.5)

P(X < K) becomes P(X < K - 0.5)

P(X ≥ K) becomes P(X ≥ K - 0.5)

P(X > K) becomes P(X > K + 0.5)

P(X = K) becomes P(K - 0.5 ≤ X ≤ K + 0.5)

From the given question, Assume that we are to determine the probability that more than 635 Americans support the bill.

Then we use the > sign.

∴

P(X > K ) becomes P(X > K + 0.5)

P(X > 635) becomes P(X > 635 + 0.5)

⇒ P(X > 635.5) tot the right.

Right of X = 635.5

Which equation best describes the line of best fit?
Andrej [43]
The y-value changes from 10 to 70 as the x-value changes from 0 to 10. That makes the slope (70 -10)/(10 -0) = 6, and the y-intercept = 10.

Selection A is the appropriate equation.

Find the distance between the two points in simplest radical form.
sweet-ann [11.9K]

Answer:

3\sqrt{13}

Step-by-step explanation:

Calculate the distance using the distance formula

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

with (x₁, y₁ ) = (- 9, 8) and (x₂, y₂ ) = (- 3, - 1)

d = \sqrt{(-3-(-9))^2+(-1-8)^2}

  = \sqrt{(-3+9)^2+(-9)^2}

  = \sqrt{6^2+81}

   = \sqrt{36+81}

   = \sqrt{117}

   = \sqrt{9(13)}

   = \sqrt{9} × \sqrt{13}

   = 3\sqrt{13}
