Answer:
e. 0.308.
Step-by-step explanation:
I can't draw the tree diagram but the answer is
P(red first) = 7/14 = 1/2
P( then black) = 4/13
P(red then black) = 1/2 * 4/13 = 2/13
P(black first) = 4/14 = 2/7
P( then red) = 7/13
P(black then red) =2/7 * 7/13 = 2/13
So Probability of red and black in any order
= 2/13 + 2/13 = 4/13
= 0.308.

How do I find the function rule???
x: 0, 1, 2, 3
y: 5, 4, 3, 2
Answer: y=-1x+5
Step-by-step explanation:
1. Use slope-intercept formula (y = mx + b) to find the slope which is represented by the variable 'b'.
m = ∆y / ∆x
m = -1 / 1
m = -1
y= -1x + b
2. Use any cooresponding x and y values to substitute into the formula. Ex: (x,y) → (1,4)
y = mx + b
4 = -1(1) + b
4 = -1 + b
5 = b
3. Plug in the values found into the formula.
y = -1x + 5

Answer:
1/6
Step-by-step explanation:
Firstly the coin will have a probability of getting 1/2 for tails and also 1/2 for heads since it is fair.
A cube has 6 sides hence will have numbers 1-6 on each side. Numbers greater than 4 on a cube will be 5,6 and both of them have a 1/6 chance of getting drawn therefore in total it is a 2/6 chance.
Probability of getting tails is 1/2 and probability of getting number greater than 4 is 2/6.
Hence the total probability will be 1/2 x 2/6 = 1/6

Javier has four cylindrical models. The heights, radii, and diagonals of the vertical cross-sections of the models are shown in the table. A cylinder. Model 1 radius: 14 cm height: 48 cm diagonal: 50 cm Model 2 radius: 6 cm height: 35 cm diagonal: 37 cm Model 3 radius: 20 cm height: 40 cm diagonal: 60 cm Model 4 radius: 24 cm height: 9 cm diagonal: 30 cm In which model does the lateral surface meet the base at a right angle? Model 1 Model 2 Model 3 Model 4
The model in which the lateral surface meets the base at right angle is : Model 1.
What is a lateral surface?The lateral surface of an object is all surfaces of that object excluding its base and top.
Analysis:
To know the exact model, we check for the models in which their dimensions form a Pythagorean triplet otherwise a right-angled triangle.
For Pythagorean triplet, the square of the diagonal must be equal to the sum of squares of the other two sides.
Model 1
Diagonal = 50cm, radius = 14cm, lateral height = 48cm
[tex](50)^{2}[/tex] = [tex](14)^{2}[/tex] + [tex](48)^{2}[/tex]
2500 = 196 + 2304
2500 = 2500. Forms Pythagorean triplet
Model 2
Diagonal= 37cm, radius = 6cm lateral height = 35cm
[tex](37)^{2}[/tex] = [tex](35)^{2}[/tex]+ [tex](6)^{2}[/tex]
1369 = 1225 +36
1369 [tex]\neq[/tex] 1261
Model 3
Diagonal = 60cm, radius = 20cm lateral height = 40cm
[tex](60)^{2}[/tex] = [tex](20)^{2}[/tex] + [tex](40)^{2}[/tex]
3600 = 400 + 1600
3600 [tex]\neq[/tex] 2000
Model 4
Diagonal = 30cm, radius = 24cm, lateral height = 9cm
[tex](30)^{2}[/tex] = [tex](24)^{2}[/tex] + [tex](9)^{2}[/tex]
900 = 576 + 81
900 [tex]\neq[/tex] 657
Therefore the lateral surface model 1 meets the base at right angle
In conclusion, the lateral surface of model 1 meets the base at right angles as the dimensions form a right-angled triangle.

Step-by-step explanation:
Find the arc length of the subtending arc for an angle of 3pi/4 radians on a circle of radius 2.5.
The arc length of the circle will be equal to 5.89 units.
What is the length of the arc?The length of the curve on the circumference of the circle making an angle with the centre is called the length of the arc of the circle.
Given that:-
Angle = 3π / 4radius = 2.5 units.The length of the arc will be calculated as:-
Arc = Angle x radius
Arc = ( 3π / 4 ) x 2.5
Arc = 5.89 units.

2x+y=26
x-y=4
Descubra o valor de x e y e explique o processo.
The correct roots of this equation is:
x = 10
y = 6
– This equation is a value substitution system. To solve it, we will: add the terms equal to x, with the sums of the equality.
2x + y = 26
x - y = 4
2x + x = 26 + 4
3x = 30
x = 30/3
x = 10
– Now, let's "take" the first equation of the system, and we'll calculate it, replacing x with its value.
2x + y = 26
2 . 10 + y = 26
20 + y = 26
y = 26 - 20
y = 6
Therefore, the roots of this equation or system is:
x = 10
y = 6
my watch gains 10 seconds every hour if it is set right on Monday at 10:30 a.m. what will it show them following Monday at 10:30 a.m.
Answer: 10:58 a.m.
Step-by-step explanation:
To solve this problem, find how many hours will pass in the given timeframe. From this Monday to next Monday, a week will pass. A week is equal to 7 days. A day has 24 hours, so multiply 7 days by 24 hours. 7*24 = 168 hours.
Since the watch gains 10 seconds every hour, multiply 168 hours by 10 seconds. This means your watch will gain 1680 seconds over the week.
To find what time the watch will be at, first find how many minutes will pass. There are 60 seconds in a minute, so divide 1680 seconds by 60 seconds. 1680/60 = 28.
Add 28 minutes to 10:30 a.m. to get a final time of 10:58 a.m.
The coordinates of the vertices of are E (-4, 5), F (-1, 1), and G (3, 4). Determine whether EFG is a right triangle and support your decision. Show all work.
Answer:
No, it will not be a right triangle
Step-by-step explanation:
Since E (-4, 5) and F (-1, 1) are both in-plane one and G (3, 4) in-plane two
The x's are wrong for E and F which would be a cause for not a right triangle
And the y for G is not either 5 or 1 which would help make the triangle a right triangle.
So the triangle ends up being an scalene triangle and not a right triangle

Find the midpoint M between V(3,7,-6) and W(-4,-8,7). Put your answer in the form (x,y,z)
Answer:
M(-1/2, -1/2, 1/2)
Step-by-step explanation:
To find the midpoint of a line segment, average the coordinates of the end points.
M = (A +B)/2
__
M = (V +W)/2
M = ((3, 7, -6) +(-4, -8, 7))/2 = (3-4, 7-8, -6+7)/2 = (-1, -1, 1)/2
M = (-1/2, -1/2, 1/2)

One thousand unit cubes are fastened together to form a large cube with edge length 10 units; this is painted and then separated into the original cubes. The number of these unit cubes which have at least one face painted is:
Based on the number of unit cubes that are fastened together, the number of cubes which will have at least one face painted on is 488 cubes.
How many cubes will have one face painted on?The cubes formed one large cube which means that each surface is one cube deep. So two cubes will be painted.
The number of unpainted cubes per surface is therefore:
= 10 - 2
= 8 cubes
Number of unpainted cubes is:
= 8 x 8 x 8
= 512 cubes
Number of cubes with one face painted:
= Total cubes - Number of unpainted cubes
= 1,000 - 512
= 488 cubes.

The density of iron is 7.8 g/cm3. an iron beam has a volume of 10,504 cm³. what is the mass of the iron beam? enter your answer as a decimal in the box.
Under the assumption of uniform iron beam and definition of uniform density, the total mass of the iron beam is equal to 81931.2 grams.
How to determine the mass of the iron beam
Let suppose that the iron beam has an uniform density, the mass of the iron beam (m), in gram, is equal to the product of its density (ρ), in grams per cubic centimeter, and its volume (V), in cubic centimeters:
m = ρ · V (1)
If we know that ρ = 10504 cm³ and V = 7.8 g/cm³, then the mass of the iron beam is:
m = (7.8 g/cm³) · (10504 cm³)
m = 81931.2 g
Under the assumption of uniform iron beam and definition of uniform density, the total mass of the iron beam is equal to 81931.2 grams.

The solution to the quadratic equation 6x² + 6 = 12x is x = 1
How to determine the solutions?The quadratic equation is given as:
6x² + 6 = 12x
Equate the equation to 0
6x² - 12x + 6 = 0
Expand the equation
6x² - 6x - 6x + 6 = 0
Factorize the expression
6x(x - 1) - 6(x - 1) = 0
Factor out x - 1
(6x - 6)(x - 1) = 0
Split
6x - 6 = 0 or x - 1 = 0
Solve for x in both instance
x = 1 or x = 1
Hence, the solution to the quadratic equation 6x² + 6 = 12x is x = 1
