As the image is magnified by a factor of 1: 7(1/4)
= 1: (29/4)
= 4/29.



The length of x must've been also increased by a factor of 4/ 29.

Using this,
The scaled value of x will be,

3(4/29)
= 12/29 units.

Which number line represents the solution set for the inequality 3(8 – 4x) < 6(x – 5)?
Marizza181 [45]

The number line which represents the solution set for inequality 3(8-4x)<6(x-5) is (3,inf).

Given an inequality 3(8-4x)<6(x-5).

We have to find the solution set for the given inequality.

<h3>What is inequality?</h3>

A statement of an order relationship greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.

3(8-4x) < 6(x-5).

⇒ 24-12x<6x-30

⇒ 24+30<6x+12x

⇒ 54<18x

⇒ x>54/18

⇒ x>3

Hence, the number line which represents the solution set for inequality 3(8-4x)<6(x-5) is (3,inf).

That is starting from 3 and goes up to infinity.

likoan [24]

The completion of the tabs are:

  • The value of \bar p is the sample proportion.
  • The value of  \bar q is found by evaluating 1-\=p
  • The value of n is the sample size.
  • The value of E is the margin of error.
  • The value of p is the population proportion.
  • α = 0.05.

<h3>What is the margin of error.?</h3>

You may calculate how many percentage points your findings will deviate from the actual population figure by using something called a margin of error.

In conclusion

  • The worth of p^ is the fraction of the sample.
  • The worth of p^ is discovered by assessing
  • The sample size is given by the number n.
  • The margin of error is expressed as E's value.
  • The population percentage is represented by the value of p.
  • α = 0.05.

In conclusion,
