Which of the following ratios is not equivalent to 2:10
A.1/5
B.2/5
C.4/20
D.6/30

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

Answer:

3/10

Step-by-step explanation:

Convert 2 number to improper fraction find a common denominator and KFC, Keep, Change, Flip.

Keep first fraction

Change / into x

And flip the other fraction (2 1/2 or 5/2) to (2/5)

3/4 x 2/5 is 3/10

Answer:

its 14 or 1/4 as you said     |     if it is not fractions and is whole numbers it is 1

Step-by-step explanation:

1/4 is the smallest value out of all of them, making it the least probable to happen

if they are not fractions, it is 1 because that is the smallest value, making it the least probable

Answer:

25%

Step-by-step explanation:

(56/224)*100

Answer:

25%

Step-by-step explanation:

56 pages of 224 pages

56/224

= 1/4

1/4 = 0.25

1/4 & 0.25 = 25%

Answer:

X=85°....

Step-by-step explanation:

you do this by first acknowledging that in any triangle 180° will be present... so 40 + 45° equals 85°..this means that the other angle in the triangle will equal 95 degrees... now, in a line there's 180° present... that means 180 minus the 95 from the angle of c equals 85.

3. 6x + 1/4y = 3-- linear equation✓

Answer:

$3 for the small drinks and $4 for the large popcorn

Step-by-step explanation:

so we know that 2 popcorns and 4 small drinks give us $20 and 2 popcorns and 2 drinks gives us 14. so $6 was taken away because of two drinks and 6÷2 equals 3 therefore $3 is how much a small drink costs. after taking away another 6 from 14 because we found the costs of drinks we get $8 for two popcorns and 8÷2 is 4 so a large popcorn costs $4

Answer:

The large popcorn bucket cost $4 and the small drink cost $3.

Answer:

10

Step-by-step explanation:

Since Kelly earns 12.50 dollars per hour, and she works 14 hours, you can multiply 12.50 by 14.

1.      12.50*14=175

Kelly gives 1/5 of her money away, so she should be left with 4/5.

2.     4/5*12.50=10

So the answer is 10.

I aint never seen two pretty best friends, its always one of em gotta be ugly

Step-by-step explanation:

Answer:

y = -3x - 5

Step-by-step explanation:

The equation of a line is given as either:

[tex]y = mx + b[/tex]  where m is the slope, and b is the y-intercept.

or

[tex]y-y_{1} = m(x-x_{1} )[/tex]  where given that you have a point (x, y), y₁ is the y-value of the point, m is the slope, and x₁ is the x-value of the point.

We can just plug in the point (0, -5) into the second equation and -3 for the slope.

However, (0, -5) tells us that this point must be a y-intercept, since the x-value of that point is 0. So, we can also just plug into the first equation -5 for the y-intercept and -3 for the slope.

So, we get:

y = -3x + (-5)

Which simplifies into:

y = -3x - 5

Answer: the answers are:6/16=9/x: 9/6=x/16: and 9/x=6/16

Step-by-step explanation:

Answer:

f(2) = g(2)

General Formulas and Concepts:

Alg I

Step-by-step explanation:

We see from the graph that f(x) and g(x) intersect at x = 2. Therefore, the point at x = 2 would be equivalent in both graphs/be a solution to both equations.

Therefore, f(2) must equal g(2), as they intersect each other at that point and have the same value of 0.

Answer: A f(2) = g(2)

Answer:

If your rounding up, its 1/2

Step-by-step explanation:

Answer:

0

Step-by-step explanation:

Y-intercept is where the line touches the y-axis, in this case it was the origin (0,0) so the y-intercept is 0

Answer:

y=-x+5

Step-by-step explanation:

(4,1)

(8,-3)

1)a slope of a line is (y2-y1)/(x2-x1)

  so (-3-1)/(8-4)

  -4/4=>m=-1

2)to find y-int replace any points in the equation by x and y

so    1=-1(4)+b

        1=-4+b

        1+4=b

so b= 5

therefore the equation is  y=-x+5   so d
