5. Which point lies on the line: y - 4 = -3(x + 2)?

Karo-lina-s [1.5K]

Answer:

(- 2, 4 )

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 4 = - 3(x + 2) ← is in point- slope form

with (a, b ) = (- 2, 4 )

ankoles [38]

Answer:

(0.6430, 0.8170)

Step-by-step explanation:

Given that during a recent drought a water utility in a certain town sampled 100 residential water bills and found out that 73 of the residences had reduced their water consumption over that of the previous year.

Sample size n = 100

Sample proportion p = $\frac{73}{100} =0.73$

q = 1-p = 0.23

Std error of proportion = $\sqrt{\frac{pq}{n} } \\=\sqrt{\frac{0.73*0.27}{100} } \\=0.04440$

95% Z critical value = 1.96

Margin of error = $1.96*0.0444 = 0.0870$

Confidence interval = sample proportion ±margin of error

0.642983946

0.817016054

(0.6430, 0.8170)
