Answer:

0.7295

Step-by-step explanation:

Given that :

Mean rate of lost time accident = 0.3 per day

probability that the number of lost-time accidents occurring over a period of 9 days will be no more than 3?

n = 9

Using binomial distribution formula :

P(x ≤3)

Probability of success (p) = 0.3

1 - p = 1- 0.3 = 0.7

nCx * p^x * (1 - p)^(n-x)

Using the binomial probability distribution calculator to save computation time :

P(x ≤3) = P(x = 0) + p(x = 1) + p(x = 2) + p(x = 3)

P(x ≤3) = 0.0403 + 0.1556 + 0.2668 + 0.2668

P(x ≤3) = 0.7295

Probabilities are used to determine the chances of events.

The probability that accidents occur no more than 3 days in 9 days is 0.7296

The given parameters are:

[tex]p = 0.3[/tex] --- the probability that an accident occurs

The probability that an accident does not occur (q) is then calculated using the following complement rule

[tex]q= 1 - p[/tex]

[tex]q= 1 - 0.3[/tex]

[tex]q= 0.7[/tex]

The probability that accidents occur no more than 3 days in 9 days is

[tex]P(x \le 3) = P(0) + P(1) + P(2) + P(3)[/tex]

Each probability is calculated using:

[tex]P = ^nC_rp^rq^{n-r}[/tex]

So, we have:

[tex]P(x \le 3) = ^9C_0(0.3)^0(0.7)^9 +^9C_1(0.3)^1(0.7)^8 + ^9C_2(0.3)^2(0.7)^7 + ^9C_3(0.3)^3(0.7)^6[/tex]

This gives

[tex]P(x \le 3) = 0.0403 + 0.1556 + 0.2668 + 0.2669[/tex]

[tex]P(x \le 3) = 0.7296[/tex]

Hence, the probability that accidents occur no more than 3 days in 9 days is 0.7296

Step-by-step explanation:

Answer:

Once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

Step-by-step explanation:

The distributive property for any binary operation Ф under * in the given set S where a, b, c ∈ S

The binary operation a * (b Ф c) = (a * b) Ф (a * c) .

The operation * distributes over the operation Ф.

Now, when factoring, suppose we have an expression ab + ac. To factor this, we have a(b + c).

To check that our answer is correct, since the expression has been factored, we then distribute the multiplication over the addition to check if the factorization is correct.

So, a(b + c) = ab + ac which is our initial expression.

So, to use the distributive property to check work when factoring, once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

The way to use the Distributive Property to check your work when factoring is;

Option D; Once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

The distributive property in algebra is expressed as; a(b + c) = ab + ac

Now, to use the distributive property to check the work when factoring, we have to expand the factored form first.

For example, we have; 2(3 + 4)

From distributive property, we have;

(2 × 3) + (2 × 4) = 14

This should be the same with the original factored expression; 2(7) = 14

Thus, the method is Once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

120+ 4(square root)15

120+15.49=135.49

135.49 is the perimeter

The perimeter of the triangle having two angles 60 degrees, 60 degrees, and one side [tex]4\sqrt{15}[/tex] is, [tex]12\sqrt{15}[/tex] or 46.47

Perimeter is a mathematical term, which means total outer boundary of a figure, we define it only for two dimensional figures.

Perimeter = Sum of length of the all the sides

Given that,

the triangle having two angles 60 degrees, 60 degrees,

and one side

It is known that, total sum of all the angles of triangle is 180°

A = 60°

B = 60°

C = ?

A + B + C = 180°

60° + 60° + C =  180°

C =60°

Hence, it is a equilateral triangle

And for equilateral triangle length of all sides are equal

a =  [tex]4\sqrt{15}[/tex]

b =  [tex]4\sqrt{15}[/tex]

c =   [tex]4\sqrt{15}[/tex]

Perimeter =  [tex]4\sqrt{15}[/tex] +  [tex]4\sqrt{15}[/tex] +  [tex]4\sqrt{15}[/tex]

Perimeter = 12√15

So, the perimeter is 12√15

Answer:

[tex]Y' = (-2, 4\frac{2}{3})[/tex]

Step-by-step explanation:

Given

[tex]Y = (-3,7)[/tex]

[tex]Scale\ Factor = (\frac{2}{3}x,\frac{2}{3}y)[/tex]

Required

Determine Y'

Y' can be solved by multiplying the scale factor by Y

i.e.

[tex]Y' = Scale\ Factor * Y[/tex]

For, the x coordinates.

[tex]Y' = \frac{2}{3}x[/tex]

Where

[tex]x = -3[/tex]

[tex]Y' = \frac{2}{3} * -3[/tex]

[tex]Y' = \frac{-6}{3}[/tex]

[tex]Y = -2[/tex]

For the y coordinates:

[tex]Y' = \frac{2}{3}y[/tex]

Where

[tex]y = 7[/tex]

[tex]Y' = \frac{2}{3} * 7[/tex]

[tex]Y' = \frac{14}{3}[/tex]

[tex]Y' = 4\frac{2}{3}[/tex]

Hence:

[tex]Y' = (-2, 4\frac{2}{3})[/tex]

The instantaneous velocity at t = 1 will be:

Step-by-step explanation:

Given the position of an object at a time [tex]t[/tex]

[tex]s\left(t\right)=-8-9t[/tex]

As we know that determining the derivative of the position function with respect to time t would give us the instantaneous velocity, so

[tex]\frac{ds}{dt}=\frac{d}{dt}\left(-8-9t\right)[/tex]

Applying the sum/difference rule:

[tex]\left(f\pm g\right)'=f\:'\pm g'[/tex]

[tex]\frac{ds}{dt}=-\frac{d}{dt}\left(8\right)-\frac{d}{dt}\left(9t\right)[/tex]

as

[tex]\frac{d}{dt}\left(8\right)=0[/tex]    ∵ [tex]\frac{d}{dx}\left(a\right)=0[/tex]

and

[tex]\frac{d}{dt}\left(9t\right)=9[/tex]   ∵ [tex]\mathrm{Take\:the\:constant\:out}:\quad \left(a\cdot f\right)'=a\cdot f\:'[/tex]  and [tex]\frac{d}{dt}\left(t\right)=1[/tex]

so the expression becomes

[tex]\frac{ds}{dt}=-\frac{d}{dt}\left(8\right)-\frac{d}{dt}\left(9t\right)[/tex]
