Answer:

B. 0.694

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome.

Given that the pain reliever is advertised as being 97%  effective, for it to be effective in 12 independent trials

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

Answer:

The moon equals 7

and the stars equal 4

Step-by-step explanation:

Equation 1:

(substitute the symbols for the numbers)

7 + 1 = 4 + 4 (<< This is correct, both sides equal 8)

Equation 2:

(again, substitute the symbols)

7 = 3 + 4

That is correct.

Answer:

  $465

Step-by-step explanation:

The problem statement tells you h represents the number of hours, and the number of hours is 7.

It also tells you f represents the number of fixtures, and the number of fixtures is 9.

And, the problem statement tells you the charge is 15h+40f, which is 15 times the number of hours plus 40 times the number of fixtures. Then the charges are ...

  15·7 +40·9 = 105 +360 = 465

Ben Frank charges $465 for the work.

Answer:

if it wants an equation, 105h+360f but if its all together then its 465$

Step-by-step explanation:

15x7=105h

40x9=360f

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].

In the teaching of the Catholic Church, an indulgence is "a way to reduce the amount of punishment one has to undergo for sins".

Answer:

In the teaching of the Catholic Church, an indulgence is "a way to reduce the amount of punishment one has to undergo for sins"

Step-by-step explanation:

Indulgence is the action or fact of indulging. (in the Roman Catholic Church) a grant by the Pope of remission of the temporal punishment in purgatory still due for sins after absolution. The unrestricted sale of indulgences by pardoners was a widespread abuse during the later Middle Ages.

Indulgence sentence example. The indulgence accentuated the division between those who accepted and those who rejected it. German chocolates are my only indulgence . I went to a party last night, and there out of five ladies three were Roman Catholics and had the Pope's indulgence for doing woolwork on Sundays.

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

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).

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)

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).

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).
