c. (2, -2)

d. (3, -2)

e. (4, -2)

f. The y-value of the coordinate is always -2. The x-value of the coordinate is always what x is stated to equal.

Step-by-step explanation:

Since the linear equation y = -2 doesn't have a slope, it will be shown as a continuous horizontal line along, touching the y-axis at it's -2 unit.

Same could be said with the various x-equations, except they will be shown as continuous vertical lines.

Answer: 0.418 < p < 0.512

Step-by-step explanation: A 95% conifdence interval for a population proportion is given by:

$p + z\sqrt{\frac{p(1-p)}{n} }$

where:

p is the proportion

z is score in z-table

n is sample size

The proportion for people who said "yes" is

$p=\frac{202}{434}$ = 0.465

For a 95% confidence interval, z = 1.96.

Calculating

$0.465 + 1.96*\sqrt{\frac{0.465(0.535)}{434} }$

$0.465 + 1.96*\sqrt{0.00057}$

0.465 ± 1.96*0.024

0.465 ± 0.047

Interval is between:

0.465 - 0.047 = 0.418

0.465 + 0.047 = 0.512

<u>The interval with 95% of confidence is between 0.418 and 0.512.</u>

Answer:

A) 4 students

B) 32.5%

C) 19/40

Step-by-step explanation:

Using set notation to solve the problem with universal set n(U) = 40

Let n(A) be the number of students that pass account

n(E) be the number of students that pass economics

n(M) be the number of students that pass mathematics

n(AUEUM)' be number of students that failed in all the 3 subjects.

n(AUEUM) be number of students that pass in all the 3 subjects.
