probability that the pain reliever will be effective
in 12 independent trials?
A. 0.116
B. 0.694
C. 0.970

Una persona hace un trabajo en 6 horas, una segunda hace el trabajo en 8 horas y una tercera hace el trabajo en 10 horas. Si las tres personas trabajan al mismo tiempo ¿Cuánto tiempo durarán haciendo el trabajo?
a) 1 16/47 horas.
b) 2 26/47 horas.
c) 3 1/47 horas.
d) 4 36/47 horas.
Answer:
b) [tex]2\dfrac{26}{47}\ \text{horas}[/tex]
Step-by-step explanation:
Tiempo necesario para completar el trabajo en primera persona = 6 horas
Trabajo hecho en 1 hora = [tex]\dfrac{1}{6}[/tex]
Tiempo necesario para completar el trabajo por segunda persona = 8 horas
Trabajo hecho en 1 hora = [tex]\dfrac{1}{8}[/tex]
Tiempo necesario para completar el trabajo por tercera persona = 10 horas
Trabajo hecho en 1 hora = [tex]\dfrac{1}{10}[/tex]
El tiempo necesario para completar el trabajo juntos viene dado por
[tex]\dfrac{1}{\dfrac{1}{6}+\dfrac{1}{8}+\dfrac{1}{10}}=\dfrac{1}{\dfrac{47}{120}}\\ =\dfrac{120}{47}=2\dfrac{26}{47}\ \text{horas}[/tex]
El tiempo necesario para completar el trabajo juntos es [tex]2\dfrac{26}{47}\ \text{horas}[/tex].

Factor the trinomial 3x2 + 13x − 10 by grouping.
Answer:
(3x - 2) (x+5)
Step-by-step explanation:
3x^2 + 13 - 10
15× - 2 = -30
15+-2 = 13.....substitute 15x - 2x in place of 13x
3x^2+15x-2x-10
Factorise the first two values, thrn the second two
3x (x+5) - 2 (x+5)
Gathering the like terms together you eill be left with the following
(3x - 2) (x+5)
The factors of the trinomial 3x² + 13x - 10 is (3x-2)(x+5).
What is Factorization?The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics.
we have,
Trinomial= 3x² + 13x - 10
Now, factories using splitting the middle term we get
3x² + 13x - 10
= 3x² + 15x - 2x - 10
= 3x( x +5) - 2(x+ 5)
= (3x - 2) (x+ 5)
So, the factors are (3x- 2(x+5)

find the missing side of the triangle
Answer:
x= 8 km
Step-by-step explanation:
measurement used:
When getting measurement the missing side occupies 1 more than a half of 15km
Answer:
x = 8km
Step-by-step explanation:
Use Pythagorean Theorem:
c2 = a2 + b2
In the diagram given, the hypotenuse (c) is 17 so substitute these values into the equation
17^2 = x^2 + 15^2
Take 15 to the power 2, to the other side.
17^2 - 15^2 = x^2
Solve to get
64 = x2
Square root both sides so
x = 8

Five less than the product of 6 and a number equals 7
Answer:12
Step-by-step explanation:you start at the beginning like 6 times 1 is 6 but 6 times two is 12 minus 5 equals 7
The statement - "Five less than the product of 6 and a number equals 7" can be modelled as (6x - 5 = 7).
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the statement -
"Five less than the product of 6 and a number equals 7"
We can model this statement as an expression as follows. Let the number be {x}. Then, we can write that -
6x - 5 = 7
Therefore, the statement - "Five less than the product of 6 and a number equals 7" can be modelled as (6x - 5 = 7).

1. When Jack and Jill work together, they can carry a cooler of
water up a hill in 12 hours. When Jill works alone it takes her
7 fewer hours than when Jack works alone. How long would it
take Jack, working alone, to carry a cooler of water up a hill?
9514 1404 393
Answer:
28 hours
Step-by-step explanation:
Let x represent Jack's time. Then Jill's is x-7. Together their rate of carrying water in hills per hour is ...
1/x + 1/(x -7) = 1/12
Multiplying by 12x(x -7) gives ...
12(x -7) +12x = x(x -7)
x^2 -31x +84 = 0 . . . . . subtract the left side and simplify
(x -3)(x -28) = 0 . . . . . . . . . . factor
x = 3 or x = 28 . . . . . . . . . . x-values that make the factors zero
We know the times must be longer than 12 hours, so the value x=3 is extraneous for this problem.
It takes Jack 28 hours to carry the cooler of water up the hill working alone.
The end of a minute hand on a clock is 5.5 inches from the center. How far will the minute hand travel over three days
Answer:
Step-by-step explanation:
Given :
Radius, r = Length of hour hand = 5.5 inches
A complete cycle is traveled in 24 hours ;
C = 2πr
C = 2 * π * 5.5 = 34.557519 inches
In 3 days : It will travel 3 full cycles
3 * C = 3 * 34.557519 inches
= 103.672557 inches
A bridge being designed will cross the river at a right angle. The equation of the left bank of the river is j = 2x+8. The center of the bridge will pass through (0,2). What is the equation of the line representing the bridge?
This is the same as y = -0.5x+2
==========================================================
Explanation:
Refer to the diagram below.
The blue line is the graph of y = 2x+8, which is the left bank of the river.
For now, ignore the y = (-1/2)x+2 in the diagram and pretend we don't know that just yet. The red line is the bridge and it's some linear equation in the form y = mx+b. We're told the bridge is perpendicular to the river, so the bridge must also be perpendicular to the riverbank.
The blue line has slope m = 2. Apply the negative reciprocal to this to end up with -1/2. This is the perpendicular slope, and the slope of the red line. Note how the two slopes (2 and -1/2) multiply to -1. Any two perpendicular lines will have their slopes multiply to -1, as long as neither line is vertical or horizontal.
Since we want the bridge to pass through (0,2), this must mean the y intercept is b = 2.
So with m = -1/2 and b = 2, we go from y = mx+b to y = (-1/2)x + 2 which is the equation of the bridge shown in red.
This is the same as y = -0.5x + 2 since -1/2 = -0.5
