Answer:

Slope = -2/1 = -2

Step-by-step explanation:

You can look at the points on the image and see the "directions" to get from one point to the next: you go down 2 and over 1. This is -2/1, which is -2.

You could also pick and two points and do a calculation. It can be any two points on the line and it will come out the same.

For example (-1,3) and (0,1) are two points on the line. To find slope, subtract the y's and put that on top of a fraction, then subtract x's and put that on the bottom.

3 - 1 goes on top.

-1 - 0 goes below.

3-1 / -1 - 0

2/-1

= -2

Slope = -2

Answer:

3.949

Step-by-step explanation:

We can use the formula to find the error bound:

EBM=(zα/2)(σn/√)

We know that σ=7 and n=17. We are also given that the confidence level (CL) is 98%, or 0.98. So, we can calculate alpha (α).

α=1−CL

=1−0.98

=0.02

Since α=0.02, we know that

α2=0.022=0.01

The value of z0.01 is 2.326. Now we can substitute the values into the formula to find the error bound.

EBM=(zα/2)(σ/√n)

=(2.326)(7/√17)

≈(2.326)(1.698)

≈3.949

So, the error bound (EBM) is 3.949.

Answer:

let us consider on inequality. Seven is greater than two on number that says one every month. Supply one with a positive intention on both sides. A tree. Then this will change. Toe three multiplied with seven is greater than three months. Playing with stool, which will give us that 21 is greater than six status. There is no change in the direction of inequality. Now I'm multiplying. The first inequality picked a negative intention on both sides and minus tree. So then this inequality will change. Toe minus string multiplied with seven is greater than minus street multiplied. Which two, which will become the don'ts that we'll get, will be minus 21 on dhe minus six according to the first inequality. If the direction it's saying the little Belgian as mine is strange even is greater than minus six, which is not possible, so the direction will get automatically reversed. On this, inequality will become minus 21 which is less than minus six. It doesn't eat for violent of the first inequality, so therefore we have seeing that Ben be multiplied the inequality by a postive intrusion on both sides. Then the direction off inequality stays the same. On the other hand, when they're multiplying both sides with a negative Indonesia, then the direction off the inequality will become reverse. So this is what is known as the multiplication property. Oh, the inequalities.

Answer:

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  15

   The  level of significance is  [tex]\alpha = 0.05[/tex]

The null hypothesis is  [tex]H_o:\mu_1 = \mu_2 = \mu_3[/tex]

The alternative hypothesis is [tex]H_a : \mu_1 \ne \mu_2 \ne \mu_3[/tex]

Generally the degree of freedom is mathematically represented  as

       [tex]df = 5 + 5 + 5 - 3[/tex]

=>     [tex]df = 12[/tex]

Generally the critical value of [tex]\alpha = 0.05[/tex] at a degree of freedom of [tex]df = 12[/tex] is

        [tex]t_{0.05 , 12} = \pm 2.1788[/tex]

Answer:

222 yd²

Step-by-step explanation:

Bottom and top area, each = 7 * 3 = 21 yd²

Two lateral surdaces, each = 7 * 9 = 63 yd²

Two lateral surdaces, each = 3 * 9 = 27 yd²

Total area = 2 x (21 + 63 + 27) = 222 yd²

Answer:

[tex]x=\frac{3\pi n}{5}[/tex]

Step-by-step explanation:

We know that [tex]cot(\frac{5x}{3})=\frac{cos(\frac{5x}{3})}{sin(\frac{5x}{3})}[/tex], so [tex]cot(\frac{5x}{3})[/tex] is undefined where [tex]sin(\frac{5x}{3})=0[/tex]:

[tex]sin(\frac{5x}{3})=0\\\\\frac{5x}{3}=\pi n\\\\5x=3\pi n\\\\x=\frac{3\pi n}{5}[/tex]

So, the discontinuities for the function [tex]f(x)=cot(\frac{5x}{3})[/tex] are where [tex]x=\frac{3\pi n}{5}[/tex] with [tex]n[/tex] being any integer.

Step-by-step explanation:

Let's write the equation with formula:- Where, x1 is -1 and y1 is 4 and m is 3Thus, The correct choice is option C.

Step-by-step explanation:

Equation of line formula=> y=mx+c

Let take point (-1,4) as (x, y) and slope m=3

4= 3(-1) +c

4= -3+c

4+3=c

7=c

Therefore by using equation of line formula we get

y= mx+c [m=3 , c=7]

y=3x+7

Realizando un corte en cada esquina del cubo como se muestra en la imagen quedarían una figura de 13 caras.

Para saber el número de caras resultante de cortar todas las puntas del cubo debemos tener en cuenta que el cubo tiene 6 caras y 8 puntas.

De acuerdo a lo anterior, debemos remplazar cada punta por una cara, debido a que cada punta va a quedar como una cara luego del corte, es decir que tendríamos que sumar 6 caras y 8 caras producto del corte de las puntas.

6 + 8 = 13

Entonces, el número de caras de esta figura sería 13.
