Least possible value of m and n are 6 and 10.

Given a perfect square is an integer that is also square of an integer.

The given m and n are positive integers such that mn > 15.

To find out the least possible value of mn;

As given 15mn is a perfect square.

[tex]\sqrt{15mn}[/tex] is to be an integer.

[tex]\sqrt{15mn} = \sqrt{5*3*m*n}[/tex]

Now, insert m = 3, n = 5;

⇒ [tex]\sqrt{5*3*m*n} = \sqrt{5^2* 3^2} = 15[/tex]

but it is mn < 15.

So, assume m = 3 * 2, n = 5 * 2;

⇒ [tex]\sqrt{5*3*m*n} = \sqrt{5*3*3*2*5*2} = \sqrt{5^2*3^2*2^2} = 30[/tex]

30 it is an integer.

As we solved that the least possible value of m and n are 6 and 10.

Answer:

The first one is a function but the second one is not.

Step-by-step explanation:

Using the vertical line test, we can check if the graphs are a function or not. Every vertical line can only touch a graph once in order for the function to pass the Vertical Line Test. If a graph passes the Vertical Line Test, it's the graph of a function. The first one has no points intersecting each other if you draw a vertical line for each point. However, if you draw vertical lines for the second graph, the points vertically intersect each other, making it not a function.

The approximate diameter of the circle is 5.77 cm

Given that :

area of circle = 28.3 cm²

How is Area of circle is calculated ?

Area of circle is calculated using formula :

A= πr²

where "π" represents 3.14 and r is radius. So now, according to given information,

Where Pi = 3.14

Hence,

A= πr²

Substitution the value of A in above formula :

28.3 = πr²

28.3 = 3.14r²

r² =28.3/3.14

r² =8.323

√r²=√8.323

r = 2.885

r = 2.885 cm Approximately.

d = 2r

d = 5.77 Approximately.

Therefore, the diameter of the circle is 5.77 cm

Answer:

n + 4

Step-by-step explanation:

n is being used to describe the position of a term.

We can see that the sequence is increasing linearly by 1.

Since the position of the next term is increasing linearly by 1, all we have to do is look at the first term and subtract 1 from it to get our constant (4).

An equation to think about this better would be

n + C = S

C is the constant we are solving for.

We know n = 1.

S is the number corresponding in the sequence with n.

1 + C = 5

Subtract 1 from both sides to isolate C.

C = 4

1 + 4 = 5  Checks out

n + 4

You don't need to include the equals sign because the problem asks for an expression which doesn't contain an equals sign unlike an equation.

The value of the card in 2005 is $15.49.

A mathematical equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.

When he retired in 1999 his card was worth $7.81 but the value has increased by $1.28 each year since then.

Therefore, the value of the card in 2005 will be:

y = 7.81 + 1.28x

where x = number of years

From 1999 to 2005 is 6 years. This will be:

= 7.81 + 1.28x

= 7.81 + 1.28(6)

= 7.81 + 7.68

= 15.49

the general formula of a parabola is

we can replace the the points to find a,b and c

First (0,4)

Then (-5,1.5) and c=4

Answer:

  x = 4

Step-by-step explanation:

You want the equation of a line that goes through point (4, 0) and has an undefined slope.

The slope of a line is the ratio of "rise" to "run." When the "run" is zero, the ratio involves division by zero, which results in the value "undefined." That is, a line with undefined slope has a "run" of zero, meaning it is a vertical line.

The equation for a vertical line is ...

  x = c . . . . . where c is some constant

We want the line to go through a point that has x-coordinate = 4, so that constant must be 4.

The equation is x = 4.

Through hypothesis testing, it can be explained that Type I error occurs when the allergist determines that the percentage of the population who are allergic to some cheese products is at least 30% when it is actually less than 30%. Similarly, Type II error occurs when the allergist assumes that the percentage of the population who are allergic to certain cheese products is less than 30% when it is actually at least 30%

There are two possible outcomes for hypothesis testing, which leads to two different sorts of conclusion-related errors. This is due to the possibility that the estimated value of the measure and the inference made about the population measure from the samples could diverge.

Let's say an allergist wants to investigate the claim that at least 30% of the population has a cheese allergy.

Let p represent the actual percentage of the population that were allergic to certain cheese products.

The following is how the hypotheses are put forth:

[tex]H_{0}:p < 0.3\\H_{a}:p\geq 0.3[/tex]

The two types of errors that can be committed by the allergist can be described as below:

(a) Type I error:

When the null hypothesis is assumed to be true when it is actually false, type I error arises.

When an allergist determines that the percentage of the population who are allergic to some cheese products is at least 30% when it is actually less than 30%, type I mistake has been committed.

(b) Type II error:

When the null hypothesis is unsuccessfully rejected even when it is false, type II error has occurred.

When an allergist assumes that the percentage of the population who are allergic to certain cheese products is less than 30% when it is actually at least 30%, type II error has occurred.

Answer:f(x)=x8−8x6+19x4−12x3+14x2−8x+9=x8−8x6+16x4+3x4−12x3+12x2+2x2−8x+8+1

which allows us to rewrite f(x) as

f(x)=x4(x2−4)2+3x2(x−2)2+2(x−2)2+1

The first three terms are clearly non-negative, and each reaches their minimum of 0 at x=2 (the first term also has a minimum at x=−2). Thus, the minimum of f(x) must be 1.

This can't really be generalized. (I mean, you can apply the approach generally, but it won't generally give you such a convenient result.) I'm not sure I would have looked for this decomposition of f(x) except for the presence of the question.

The unit rate represented in the equation y = 3/5x is the value multiplying x, that is, the unit rate is 3/5.

In order to find the unit rate of each table, we just need to divide the y-values by the x-values.

So, the unit rate of the first table is:

The value 4/3 is greater than the value 3/5.

In the second table we have that:

The value 4/5 is greater than the value 3/5;

In the third table, we have that:

In order to compare this fraction with 3/5, we need to make them be in the same denominator, so we have to calculate the least common multiple of the denominators.

Since 5 and 31 are prime numbers, the LCM is the product of both numbers.

So we have that:

The number 90/155 is lesser than 93/155, therefore 18/31 is lesser than 3/5, so the answer is the third table.
