Through: (1,-5), perpendicular to y=18x+26

stiks02 [169]

Answer:

Step-by-step explanation:

If you're asking for the equation of a line that goes through (1,-5) and is perpendicular to y=18x+26 here's what you do.

1. find the slope of the new line by taking the negative reciprocal of the slope of the first line ( $-\frac{1}{18}$ )

2. plug in the point (1,-5) and the new slope into the point slope form equation

$y_{2} -y_{1}=m(x_{2}-x_{1})$

3.Now that you have y-(-5)= -1/18(x-1) simplify

3.a y-(-5)= -1/18x + 1/18

3.b y=-1/18x - 89/18

4. final equation you get is y = -1/18 - 89/18

Dada una distribución t de Student con 15 grados de libertad, calcule el valor de t1 tal que a) el área a la derecha de t1 sea 0

nikitadnepr [17]

Answer:

a) t₁ = 2,947

b) t₁ = 2,131

c) t₁ = 1,753

d) t₁ = 2,947 -t₁ = -2,947

e) t₁ = 2,131 -t₁ = -2, 131

Step-by-step explanation:

a) t₁ para el área a la derecha de 0,01

En la tabla t- student el t correspondiente a 0,01 es:

t₁ = 2,947

b) t₁ para el área a la izquierda sea de 0,95. Es igual al t para el cual el área de la drecha es 0,05

t₁ = 2,131

c) t₁ para que el área de la derecha sea 0,10

t₁ = 1,753

d) Buscar t₁ para el cual las áreas de derecha de (t₁) más la de la izquierda de (- t₁ ) sea 0,01.

Si el área es de 0,01 quere decir que la mitad, es decir 0,005 es el área para una cola, luego

t₁ = 2,947 y -t₁ = -2,947

e) Para que el área entre - t₁ y t₁ sea 0,95

t₁ = 2,131 y -t₁ = -2, 131

5 + x = -2<br> I need work and answer!!!!

JulsSmile [24]

We need to get x by itself.

We do that by subtracting 5 from both sides.

This leaves us with <em>x = -7</em>.

So x = -7 is the solution.

The Area of a rectangular patio is 5 5/8 square yards,and it's length is 1 1/2 yards.What is the patio's width,in yards?

fgiga [73]

Take both mixed numbers (a whole number plus a fraction) and turn them into improper fractions ( a numerator (top number) bigger than the denominator (bottom number). To do this, multiply the denominator by the whole number, and add the result to the numerator.
5 5/8 will become 45/8
1 1/2 will become 3/2.
Area is length* width, so width would be Area/ length. So 45/8 is the area and 3/2 is the length. Now you have (45/8)/(3/2). To divide fractions, take the second fraction and flip the numerator and denominator, forming the reciprocal (2/3). Now multiply 45/8 and 2/3
The result is 90/24, and simplifying would get 15/4, or 3 3/4. This is the width(or length)
