First of all we will solve for x and then with the value of x we will find the answer to the second question...

\tt \: 9x + 12 = 48

\tt \: 9x = 48 - 12

\tt \: 9x = 36

\boxed{ \bf \: x = 4}

<h3>Now, </h3>

\sf \: x - 10 \\  \sf \: 4 - 10  \\  \sf \:  - 6

Answer:

x - 10 = -6

Step-by-step explanation:

9x + 12 = 48

Subtract 12 from both sides. 

9x + 12 = 48

      - 12  - 12

+ 12 and - 12 cancel out. 48 - 12 is 36. 

9x = 36

Divide 9 from both sides.

9x = 36

÷ 9  ÷ 9

9 ÷ 9 cancels out. x is left. 36 ÷ 9 is 4.

x = 4

Knowing x = 4, solve the equation.

x - 10 = ?


Plug in 4.

4 - 10 = -6

4 - 10 equals -6. This is your answer.

Hope this helped!

Answer: -1.5

Step-by-step explanation:

When population standard deviation is known, then the formula to find the z-test statistic for population mean is given by :-

z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

, where n= Sample size.

\mu = Population mean

\overline{x} = Sample mean

\sigma= Population standard deviation.

As per  given , we have \mu=120 (average infants contracted typhoid each month)

\sigma=40

n= 4 (No. of months)

\overline{x}=90

Then , the value of the appropriate test statistic will be :

z=\dfrac{90-120}{\dfrac{40}{\sqrt{4}}}

z=\dfrac{-30}{\dfrac{40}{2}}

z=\dfrac{-30}{20}

z=-1.5

Hence, the value of the test statistic = -1.5

If A ⊂ B, then which of the following describes the relationship between A and B?
Amanda [17]

A set is a well-defined collection of objects. Each object in a set is called an element of the set. Two sets are equal if they have exactly the same elements in them.

A set is a subset of another set if all elements of the set are elements of the set . In other words, the set is contained inside the set . The subset relationship is denoted as A ⊂ B .The relationship of one set being a subset of another is  also called inclusion  or we can say Set B may have more elements than A does.

Option 4 .Set B may have more elements than A does is the right answer.
