Solution:

As we have to write an expression , which evaluates to true if the value of the integer variable x is divisible (with no remainder) by the integer variable y, y≠0.

so, when x is divided by y we should get remainder as 0.

Using Euclid division lemma

x= y* q + m, i.e when an integer x is divided by y gives quotient q and remainder m.

Here , m=0

So, x = q * y

So, the expression which describes the above relationship is ,

\frac{x}{y}=q, where q is Quotient.

Answer:

x=ky , where k is a constant.

Step-by-step explanation:

We are given that x and y are variables having integer values where y ≠ 0.

It is required to write an expression such that 'x is exactly divisible by y' i.e. there is no remainder.

Let us consider x= 12 and y = 4 ( ≠ 0 ),

Then, \frac{x}{y} =\frac{12}{4}=3 i.e. x = 12 is completely divisible by y = 4.

It gives the relation x = 3y and also, this relation x=3y is the true for x =12 and y =4.

Hence, the required expression is x=ky , where k is a constant.

SpyIntel [72]

Answer:

18 and 27

Step-by-step explanation:

Let x = first (smaller) number

Let y = second (larger) number

Sum of two numbers is 45:

⇒ x + y = 45

The greater number is 9 more than the other number:

⇒ y = x + 9

Substitute  y = x + 9  into  x + y = 45  and solve for x:

⇒ x + (x + 9) = 45

⇒ 2x + 9 = 45

⇒ 2x = 36

⇒ x = 18

Substitute found value for x into  y = x + 9  and solve for y:

⇒ y = 18 + 9

⇒ y = 27

Therefore, the two numbers are 18 and 27

The population standard deviation for the typing speeds for secretaries is 4 words per minute. If we want to be 90% confident th
Oksana_A [137]

Answer:

The minimum sample size that should be taken is 62.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.9}{2} = 0.05

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.05 = 0.95, so z = 1.645

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

If we want to be 90% confident that the sample mean is within 1 word per minute of the true population mean, what is the minimum sample size that should be taken

This is n when M = 1, \sigma = 4. So

M = z*\frac{\sigma}{\sqrt{n}}

1 = 1.96*\frac{4}{\sqrt{n}}

\sqrt{n} = 4*1.96

(\sqrt{n})^{2} = (4*1.96)^{2}

n = 61.5

The minimum sample size that should be taken is 62.
