Answer:

No. Rational numbers are different from irrational numbers. Rational numbers are numbers that can be written as a fraction. Rational numbers can be a terminating decimal (a number with digits that end/do not repeat) or a repeating decimal (a number with digits that repeat continuously in a pattern). On the other hand, an irrational number is a number that is continuous, and its digits are random.

Answer:

x=106

Step-by-step explanation:

Let's solve your equation step-by-step.

−12+x−34=60

Step 1: Simplify both sides of the equation.

−12+x−34=60

−12+x+−34=60

(x)+(−12+−34)=60(Combine Like Terms)

x+−46=60

x−46=60

Step 2: Add 46 to both sides.

x−46+46=60+46

x=106

Answer:

Option A) reject null hypothesis if z is greater than 1.645

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 250

p = 30% = 0.3

Alpha, α = 0.05

Number of women belonging to union , x = 75

First, we design the null and the alternate hypothesis

$H_{0}: p = 0.3\\H_A: p > 0.3$

This is a one-tailed(right) test.

Rejection Region:

$z_{critical} \text{ at 0.05 level of significance } = 1.645$

So, the rejection region will be

$z > 1.64$

That is we will reject the null hypothesis if the calculated z-statistic is greater than 1.645

Option A) reject null hypothesis if z is greater than 1.645
