A game has 50 cards with 10 each numbered 1 to 5,and a player must draw a 2 or a 3 to move out of the "start" position.
Answer:
The question isn't complete, so I will assume that we want to find the probability of moving out of the start position.
First, we know that there is a total of 50 cards.
of these 50 cards, we have:
10 with the number 1
10 with the number 2
10 with the number 3
10 with the number 4
10 with the number 5
To move out of the starting position, we need to draw a 2 or a 3.
And we have 10 of each, then there are 20 cards that allow us to move out of the start position.
The probability of moving out of the starting position in the first draw, is equal to the quotient between the number of cards that allow us to move out of the starting position (20) and the total number of cards (50), this is:
P = 20/50 = 2/5 = 0.4
What is "y" when x = -2 in the equation y = 2x + 5
Answer:
2 x -2 + 5
-4 + 5
1 = y
Step-by-step explanation:
Plug in the value of X and do the equation.
Answer:
y = 1
Step-by-step explanation:
When x = -2 :
y = 2x + 5
y = 2(-2) + 5
y = -4 + 5
y = 1

Describe the steps you can use to graph the function y=2x^2-8
Answer:
The first thing you need to find is the axis of symmetry by using
-b/2a
after you find that, use it to find the vertex of
x
2
+
8
In this case x should equal
0
so
y
=
0
2
+
8
giving just 8
the y-intercept is 8 as
c
=
8
the graph should look like this
graph{x^2+8 [-11.5, 8.5, 0.84, 10.84]}
it is a parabola.

A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 70% pure antifreeze. The company wants to obtain 140 gallons of a mixture that contains 20% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed
Answer:
40 gallons of premium antifreeze and 100 gallons of water should be used to obtain 140 gallons of a mixture that contains 20% pure antifreeze.
Step-by-step explanation:
Since a chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture, and the premium antifreeze solution contains 70% pure antifreeze, and the company wants to obtain 140 gallons of a mixture that contains 20% pure antifreeze, to To determine how many gallons of water and how many gallons of the premium antifreeze solution must be mixed, the following calculation must be performed:
50 x 0.7 + 50 x 0 = 35
40 x 0.7 + 60 x 0 = 28
30 x 0.7 + 70 x 0 = 21
29 x 0.7 + 71 x 0 = 20.3
28.57 x 0.7 + 71.43 x 0 = 20
140 x 0.2857 = 40
Therefore, 40 gallons of premium antifreeze and 100 gallons of water should be used to obtain 140 gallons of a mixture that contains 20% pure antifreeze.
Which best describes the function represented by the data in the table? linear with a common ratio of 2 linear with a common first difference of 2 quadratic with a common ratio of 2 quadratic with a common first difference of 2
Answer:
linear with a common first difference of 2
Step-by-step explanation:
If this is linear, the common first difference, or slope, will be the same throughout the entire table.
The formula for slope is

For the first set of points, we have:
m=(0--2)/(-2--3) = (0+2)/(-2+3) = 2/1 = 2
For the second set of points, we have:
m = (4-0)/(0--2) = 4/(0+2) = 4/2 = 2
For the third set of points, we have:
m = (12-4)/(4-0) = 8/4 = 2
The rate of change, or slope, is constant; this makes the function a linear function with a common first difference of 2

Solve for x. The figure is a parallelogram
Answer:
x = 1
Step-by-step explanation:
The opposite angles in a parallelogram are congruent, then
94x + 1 = 95 ( subtract 1 from both sides )
94x = 94 ( divide both sides by 94 )
x = 1

Solve (find x intercepts) using the quadratic formula
f(x)= -5x^+9x-4
Answer:
[tex]x[/tex]-intercepts at [tex](1,0)[/tex] and [tex](0.8,0)[/tex]
Step-by-step explanation:
A quadratic in the form [tex]ax^2+bx+c=y[/tex] crosses the [tex]x[/tex]-axis when [tex]y=0[/tex].
The first step is replacing [tex]f(x)[/tex] with [tex]y[/tex].
So: [tex]y= -5x^2+9x-4[/tex]. With the information above, we can find the [tex]x[/tex] intercepts by setting [tex]y = 0[/tex].
Therefore [tex]0=-5x^2+9x-4[/tex].
Now we can use the quadratic formula because it is in the form [tex]ax^2+bx+c=0[/tex].
Note the quadratic formula: [tex]\frac{-b\frac{+}{-}\sqrt{b^2-4ac} }{2a } = x[/tex].
To find the values of [tex]a[/tex],[tex]b[/tex] and [tex]c[/tex] we can compare the equation to the general equation.
Therefore: [tex]a=-5[/tex], [tex]b=9[/tex] and [tex]c=-4[/tex].
Now put these values into the quadratic formula:
[tex]\frac{-9\frac{+}{-}\sqrt{(9)^2-4(-5)(-4)} }{2(-5) } = x[/tex]
And simplify:
[tex]\frac{-9\frac{+}{-}\sqrt{81-80} }{-10 }[/tex] , [tex]\frac{-9\frac{+}{-}\sqrt{1} }{-10 }[/tex].
[tex]\sqrt{1} =1[/tex], therefore [tex]x = \frac{-9\frac{+}{-}1 }{-10 }[/tex]
Now we can have two values for [tex]x[/tex]. One when we take away the discriminant ([tex]b^2-4ac[/tex]) and one when we add it.
So [tex]x = \frac{-10}{-10} = 1[/tex]
or
[tex]x = \frac{-8}{-10} = 0.8[/tex]
Therefore [tex]x[/tex]-intercepts at [tex](1,0)[/tex] and [tex](0.8,0)[/tex]
