The outcome P-Value is 0.0179 when Zstat = +2.10

According to the statement

we have given the value of Z-Stat which is +2.10

And we have to find the P value when H0 is rejected only in the upper tail

Z-stat is defined as the Z-score indicates how much a given value differs from the standard deviation. The Z-score, or standard score, is the number of standard deviations a given data point lies above or below mean.

And

we know that the relationship between Z-Stat and the p value is the P-Value is calculated by converting your statistic (such as mean / average) into a Z-Score.

So, the outcome p value is 0.0179

So, The outcome P-Value is 0.0179 when Zstat = +2.10

The limit for the given piecewise function does not exist(DNE).

4th option is correct.

In mathematics, limits are the points at which a function approaches the output for the specified input values. Calculus and mathematical analysis depend heavily on limits, which are required to determine integrals, derivatives, and continuity. It is applied during the analysis process and always focuses on the function's behavior at a certain time.

Unique real numbers are limits in mathematics.

According to the question,

Left hand limit of the function= -5(3)+4 = -15+4 = -11

Answer: [tex]a=\frac{b}{zm-1}[/tex]

Step-by-step explanation:

Let's first multiply both sides by m to get rid of the denominator.

[tex]za=\frac{a+b}{m}\\zam=a+b[/tex]

Now, we have an a on both sides of the equation. It will be easier to solve if there is only one, so let's divide both sides by a.

[tex]\frac{zam}{a}=\frac{a+b}{a}\\zm=\frac{a}{a}+\frac{b}{a}\\zm=1+\frac{b}{a}[/tex]

The 1 on the right can be moved to the left to isolate the fraction.

[tex]zm-1=\frac{b}{a}[/tex]

We want to get a by itself, so let's multiply it on both sides to remove it from the denominator.

[tex]a(zm-1)=b[/tex]

Finally, we can divide zm-1 from both sides to get a by itself.

[tex]a=\frac{b}{zm-1}[/tex]

The formula used to figure out the costs is

C(x) = 2885 + 30x

2885 is the total of the fixed costs -

Now the problem gets sort of complicated. If the company could print an unlimited amount of pages, the 2885 remains the same, no matter what.

The slope of the median of the triangle whose vertices are P(-6,1),Q(-2,5) R(8,1) and passes through R is -1/6.

Given that vertices of triangle is P(-6,1),Q(-2,5),R(8,1) and there is a median which passes through R.

Median of a triangle is a line segment which originates from a vertex of triangle and divides the opposite side in two equal parts. let median touches the line at L point.

When line passes through R then it must be a perpendicular on PQ. The coordinates of L is {(-2-6)/2,(5+1)/2}=(-4,3)

Now because median passes through R,it will be LR and we know that the formula of calculating slope of line from two points is [tex](y_{2} -y_{1} )/(x_{2} -x_{1} )[/tex] where [tex](x_{1} ,y_{2} ),(x_{2} ,y_{2} )[/tex] are the points of the end points of line.

Slope=(1-3)/(8+4)

=-2/12

=-1/6

Hence the slope of the median of the triangle whose vertices are P(-6,1),Q(-2,5) R(8,1) and passes through R is -1/6.

The pricing scheme of the function is (a) The first two hours cost $2, between two hours and six hours cost $2 per hour, and all hours after that cost $1.

The points are given as:

The constant interval implies that the first two hours cost $2

Next, we calculate the slope/rate of the other points.

This is done using

m = (y2 - y1)/(x2 - x1)

So, we have:

To find the equation of hyperbola, the following steps must be taken. You need to identify;

The general equation of a hyperbola can be expressed as

[tex]x^{2}[/tex]/[tex]a^{2}[/tex] - [tex]y^{2}[/tex]/[tex]b^{2}[/tex] = 1

From the graph, we have the following parameters

a = 3

[tex]a^{2}[/tex] = [tex]3^{2}[/tex] = 9

b = 2

[tex]b^{2}[/tex] = [tex]2^{2}[/tex] = 4

The equation of a hyperbola can be expressed as

[tex]x^{2}[/tex]/9 - [tex]y^{2}[/tex]/4 = 1

The vertices = V(+/-a,0) = (+/-3,0)

The center = C(0,0)

The focus = F(+/-C, 0)

Where [tex]C^{2}[/tex] = [tex]a^{2}[/tex]  + [tex]b^{2}[/tex]

C = [tex]\sqrt{9 + 4}[/tex]

C = [tex]\sqrt{13}[/tex]

Focus = F(+/- [tex]\sqrt{13}[/tex], 0)

The general equation for asymptote = +/- b/a X

Answer:

x = 5 ,  x = - 6

Step-by-step explanation:

First we factor using factorisation method :

We need 2 numbers that multiply to give +1 and add to give -30 :

To find these numbers we write out all the factors of 30 :

1, 30

2 , 15

3 , 10

5 , 6    ----> These must be the numbers as -5+6 = 1

Now we split +x into -5x and +6x :

x² -5x + 6x -30 = 0

Factor the first 2 terms together and the last two terms :

x(x-5) + 6(x-5) = 0

Keep 1 bracket and terms outside the brackets collect them into one:

(x-5)(x+6) = 0

We know that 1 of these brackets must be equal to zero as anything multiplied by zero = 0

Either x - 5 =0      OR x + 6 = 0

So x = 5                x = - 6

These are our final answers

Answer:

First answer is 1200

Second answer is 900 for each new employee

Step-by-step explanation:

First answer:

2200+1300+800+940+560+x = 7000

5800+x = 7000 subtract 5800 from both sides and you get your answer

x = 1200

Second answer:

x = 900.  Each of the two employees made 900 a month or 1800 a month for both of them.

To find the average we take the total salaries and divide by the number of people to find the average salary.  In this case, we know the average and we know all of the salaries, but two.  We can figure this out.

(7000 + 2x)/8 = 1100  multiple both sides by 8 to clear the fraction/

7000 +2x = 8800  Subtract both sides by 7000

2x = 1800  Divide both sides by 2

x = 900
