What is the probability that a standard number cube will show a two, five, or six when it is rolled?
Answer:
[tex]p=0.5[/tex]
Step-by-step explanation:
A standard die has six numbers (1 through 6). That means there is a 1/6 probability of rolling any one number. There is a 3/6 probability of rolling one of the selected numbers which simplifies to 1/2 or 0.50
which expression could be used to determine the product of -4 and 3 1/4
Answer:
B (-4)(3) + (-4)(1/4)
Step-by-step explanation:
We must find the product of -4 and 3 1/4, which is (-4)(3 1/4). We know that 3 1/4 = 3 + 1/4, so we substitute that to the expression we want.
(-4)(3 1/4) = (-4)(3 + 1/4)
Using the distributive property, we distribute the -4 to the 3 and the 1/4 and the expression becomes
(-4)(3 + 1/4) = (-4)(3) + (-4)(1/4)
I hope this helps! :)

Step-by-step explanation:
1 cup = 8 ounces
A is false.
1 quart = 4 cups
7 qt = 28 cups
28 + 4 = 32
32 < 34
B is false.
1 gallon = 8 pints
4 gallons = 32 pints
31 < 32
C is true.
1 gallon = 4 quarts
5 gallons = 20 quarts
20 < 21
D is true.

Brainliest, 10 Points, 5 stars. Solving & Graphing Systems Of Equations. Find the solution of this system of equations.
9514 1404 393
Answer:
(x, y) = (-7, 5)
Step-by-step explanation:
I find a graphing calculator to be useful for solving equations by graphing. The graph shows the solution to be ...
(x, y) = (-7, 5)
__
In these equations, the y-coefficients are the same, so we can eliminate y by subtracting the first equation from the second.
(4x -6y) -(-2x -6y) = (-58) -(-16)
6x = -42 . . . . . . . . . simplify
x = -7 . . . . . . . . divide by 6
Substituting into the first equation gives ...
-2(-7) -6y = -16
6y = 30 . . . . . . . . . . add 16+6y to both sides
y = 5 . . . . . . . . .divide by 6
The solution is (x, y) = (-7, 5).

Answer:
5 (cm)
Step-by-step explanation:
1. according to the condition in ΔABC: AC=BC, m∠C=90°. Then m∠B=m∠A=45° and
2. x=AC=AB/√2; ⇔ x=5 (cm).
Answer:
x=5 cm
Step-by-step explanation:
triangle ABC is an isoceles triangle
so BC=AC and angle A=angle B
BC=X and angle A=theta
angle B and angle A both is theta degree because base angles of an isosceles triangle are equal
to find angle A and B
angle A + angle B + angle c=180 degree (sum of interior angles of a triangle)
theta + theta +90=180
2theta=180-90
2theta=90
theta=90/2
theta=45 degree
sin both angle A and angle B are theta their value is 45 degree.
For side x
now using pythagoras theorem
take theta as reference angle
using sin rule
sin 45=opposite/hypotenuse

Answer:
5196
Step-by-step explanation:
So it's 5040+(-156)
We have to find the absolute value
|-156|=156
5040+156=5196
Answer:
5196 m
Step-by-step explanation:
The sea is level = 0
If Punack Jaya, is 5040 m above sea level then it would be = + 5040 m
If Lake Assal is 156 m below sea level then it would be = - 156 m
The difference between the two elevations:
= 5040 - (-156)
= 5040 + 156 --> two negatives create a positive
= 5196 m

Consider a different experiment: EXPERIMENT: A bag contains 3 red balls, 4 blue balls, 4 green balls and 3 yellow balls. One ball is drawn at random and then returned to the bag. Then a ball is drawn again, possibly the same one or a different one.
(a) Specify the sample space (set of outcomes) and probability distribution of the outcomes.
(b) What is the probability that both balls drawn were red balls?
(c) Starting over with all 14 balls back in the bag, what is the probability that both draws were balls of different colors?
Answer:
a) Sample space = RR, RB, RG, RY, BB, BR, BG, BY, GG, GR, GB, GY, YY, YR, YB, YG .
probability distribution of outcomes
= (3/14*3/14), (3/14*4/14), (3/14*4/14), (3/14*3/14), (4/14 *4/14 ), (4/14*3/14), (4/14 * 4/14), (4/14 * 3/14 ), ( 4/14 *4/14 ), (4/14*3/14), ( 4/14 *4/14 ),
(4/14*3/14), (3/14 *3/14 ), (3/14*3/14), (3/14 *4/14 ), ( 3/14 * 4/14 )
b) 0.0459
c) ( 3/14 * 4/14 ) + ( 3/14 * 4/14 ) + ( 3/14 * 3/14 ) + ------ ( 3/14 * 4/14 )
Step-by-step explanation:
Total number of balls = 3 + 4 + 4 + 3 = 14 balls
3 Red balls = 3/14
4 blue balls = 4/14
4 green balls = 4/14
3 yellow balls = 3/14
a) Determine the sample space and probability distribution of outcomes
since ball is drawn with replacement
Sample space = RR, RB, RG, RY, BB, BR, BG, BY, GG, GR, GB, GY, YY, YR, YB, YG .
i.e. The sample space has 16 possible combination
probability distribution of outcomes
= (3/14*3/14), (3/14*4/14), (3/14*4/14), (3/14*3/14), (4/14 *4/14 ), (4/14*3/14), (4/14 * 4/14), (4/14 * 3/14 ), ( 4/14 *4/14 ), (4/14*3/14), ( 4/14 *4/14 ),
(4/14*3/14), (3/14 *3/14 ), (3/14*3/14), (3/14 *4/14 ), ( 3/14 * 4/14 )
b) Determine P( R and R )
P ( R and R ) = 3/14 * 3/14
= 9/196 = 0.0459
C) Determine probability of drawing two different balls
P( R and B ) + P ( R and G ) + P ( R and Y ) + ------ P ( Y and G )
= ( 3/14 * 4/14 ) + ( 3/14 * 4/14 ) + ( 3/14 * 3/14 ) + ------ ( 3/14 * 4/14 )
Suppose F⃗ (x,y)=(x+3)i⃗ +(6y+3)j⃗ . Use the fundamental theorem of line integrals to calculate the following.
(a) The line integral of F⃗ along the line segment C from the point P=(1,0) to the point Q=(3,3).
∫CF⃗ ⋅dr⃗ =?
(b) The line integral of F⃗ along the triangle C from the origin to the point P=(1,0) to the point Q=(3,3) and back to the origin.
∫CF⃗ ⋅dr⃗ =?
In order to use the fundamental theorem of line integrals, you need to find a scalar potential function - that is, a scalar function f(x, y) for which
grad f(x, y) = F(x, y)
This amounts to solving for f such that
∂f/dx = x + 3
∂f/∂y = 6y + 3
Integrating both sides of the first equation with respect to x gives
f = 1/2 x ^2 + 3x + g(y)
Differentiating with respect to y gives
∂f/∂y = dg/dy = 6y + 3
Solving for g gives
g = ∫ (6y + 3) dy = 3y ^2 + 3y + C
and hence
f(x, y) = 1/2 x ^2 + 3x + 3y ^2 + 3y + C
(a) By the fundamental theorem, the integral of F along any path starting at the point P (1, 0) and ending at Q (3, 3) is
∫ F(x, y) • dr = f (3, 3) - f (1, 0) = 99/2 - 7/2 = 46
(b) Now we're talking about a closed path, so the integral is simply 0. We can verify this by checking the integral over the origin-containing paths:
• From the origin to P :
∫ F(x, y) • dr = f (1, 0) - f (0, 0) = 7/2 - 0 = 7/2
• From Q back to the origin:
∫ F(x, y) • dr = f (0, 0) - f (3, 3) = 0 - 99/2 = -99/2
Then the total integral is 7/2 + 46 - 99/2 = 0, as expected.

Step-by-step explanation:
7 + 2x + 3 = x + 10
2x - x = 10 - 7 - 3
x = 0
What?
I don't think this helps...
Answer:
x = 0.
Step-by-step explanation:
The distance between the point U and W are x + 10 and 2x + 3 + 7 so we can make the following equation:
x + 10 = 2x + 3 + 7
x + 10 = 2x + 10
Subtract 10 from both sides:
x = 2x
Subtract x from both sides:
0 = x
x = 0
If a quadratic equation is given to you in vertex form, what is the vertex?
If for example, you were given y = 2(x-3)^2 + 5, then the vertex is (3,5)
As another example, the equation y = 7(x+1)^2 + 10 has the vertex (-1,10)
The general vertex form is y = a(x-h)^2 + k with the vertex (h,k)
Answer:
(-h,k)
Step-by-step explanation:
vertex form:
y=a(x-h)^2+k
switch sign of h and you get the x
keep sign of k and you get y
ex- 3(x-5)+7
vertex=(5,7)

use algebraic manipulation to find the minimum sum-of-products expression for the function x1x2'x3' + x1x2x4+x1x2'x3x4'
The minimum sum-of-products expression for the given Boolean function is x₁[x₂'x₃' + x₂'x₄' + x₂x₄] .
To find the minimum sum-of-products expression for the given Boolean function, we can use algebraic manipulation techniques, including Boolean algebra laws and Karnaugh maps.
Let's start with the given expression:
F = x₁x₂'x₃' + x₁x₂x₄ + x₁x₂'x₃x₄'
F = x₁[x₂'x₃' + x₂x₄ + x₂'x₃x₄']
F = x₁[x₂'(x₃' + x₃x₄') + x₂x₄] ....(1)
As we know that the Boolean rule as:
a + bc = (a + b)(a + c)
a' + a = 1
As per the equation (1),
F = x₁[x₂'{(x₃' + x₃)(x₃'+x₄') + x₂x₄]
F = x₁[x₂'x₃' + x₂'x₄' + x₂x₄]
Thus, the minimum sum-of-products expression for the given Boolean function is x₁[x₂'x₃' + x₂'x₄' + x₂x₄] .
