Choose the correct equation in point-slope form for the line that passes through the point with the given slope. (2, -1), m= -3

Inga [223]

Y - y1 = m(x - x1)
slope(m) = -3
(2,-1)...x1 = 2 and y1 = -1
now we sub....pay attention to ur signs
y - (-1) = -3(x - 2)....not done yet

Hoochie [10]

Solution :

Given :

National mean score of the reading test that is conducted the NAEP = 288

Standard deviation of the score = 38

Therefore, P(X > x) = 0.25

P (Z > $\frac{x-288}{38}$ = 0.674)

$\frac{x-288}{38} = 0.674$

$x=288+(38 \times 0.674)$

x = 326.67

Therefore, the highest score that is needed for the students to be in the top of 25 percent among the students those who take the exam.
