Answer:

Step-by-step explanation:

The GCF (Greatest Common Factor) for 18 and 36 would be 18 because, the GCF of two non-zero integers, x(18) and y(36), is the greatest positive integer m(18) that divides both x(18) and y(36) without any remainder.

Answer:

x - 2y = - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given 2x + y = 3 ( subtract 2x from both sides )

y = - 2x + 3 ← in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-2}$ = $\frac{1}{2}$ , thus

y = $\frac{1}{2}$ x + c ← is the partial equation

To find c substitute (5, 4) into the partial equation

4 = $\frac{5}{2}$ + c ⇒ c = $\frac{3}{2}$

y = $\frac{1}{2}$ x + $\frac{3}{2}$ ← in slope- intercept form

Multiply through by 2

2y = x + 3 ( subtract 2y from both sides )

0 = x - 2y + 3 ( subtract 3 from both sides )

- 3 = x - 2y , that is

x - 2y = - 3 ← in standard form

A government watchdog association claims that 70% of people in the U.S. agree that the government is inefficient and wasteful. Y

Answer:

Option D) There is sufficient evidence that the true population proportion is not equal to 70%.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 1165

p = 70% = 0.7

Alpha, α = 0.02

Number of people who agreed , x = 746

First, we design the null and the alternate hypothesis

$H_{0}: p = 0.7\\H_A: p \neq 0.7$

This is a two-tailed test.

Formula:

$\hat{p} = \dfrac{x}{n} = \dfrac{746}{1165} = 0.64$

$z = \dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

Putting the values, we get,

$z = \displaystyle\frac{0.64-0.7}{\sqrt{\frac{0.7(1-0.7)}{1165}}} = -4.46$

Now, $z_{critical} \text{ at 0.02 level of significance } = \pm 2.33$

Since,

Since, the calculated z statistic does not lie in the acceptance region, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.

Thus, there is enough evidence to support the claim that the true proportion differs from 70%.

Option D) There is sufficient evidence that the true population proportion is not equal to 70%.
