Here’s another way to think about the number line model for 2 – (-3): if we were adding 2 + (-3), we’d first move two units to t

he right. Then, we’d move three units to the left, because we move left when adding negative integers. But instead, we’re subtracting -3. Addition and subtraction are inverse operations, or opposite operations; they undo one another. So we move in the opposite direction, right, and end up with a sum of 5. As a result, the number line models for 2 – (-3) and 2 + 3 are identical. This shows that subtracting a negative integer is the same as adding a positive integer.

Classify the random variables below according to whether they are discrete or continuous.
Ann [662]

Answer:

a) Continuous

b) Continuous

c) Discrete

d) Continuous

e) Discrete

Step-by-step explanation:

Discrete variable

Discrete variables are numerical variables that have a countable number of values between any two values. A discrete variable is always numerical. For example, the number of people with blood type Upper A in a random sample of 42 people.

Continuous variable

Continuous variables are numerical variables that have an infinite number of values between any two values. A continuous variable can be numeric or date / time. For example, the time it takes to fly from City Upper A to City Upper B.

A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test.
Tomtit [17]

The company cannot build  10 child bikes and 12 adult bikes No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 , Option A is the correct answer.

<h3>What is System of Inequality ?</h3>

System of inequality represent system of inequalities that satisfies common condition.

It is given that

Each child bike requires 4 hours to build and 4 hours to test.

Each adult bike requires 6 hours to build and 4 hours to test.

Total building hours = 120

Total testing hours = 100

If c represents child bikes and a represents adult bikes, can the company build 10 child bikes and 12 adult bikes in a week.

6a + 4c ≤ 120

4a +4c ≤100

On solving this system of Inequality

a ≤ 10

which is less than required , and so

No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

Therefore Option A is the correct answer.
