calculate the probability that there will be at least four months in which no accidents occur before the fourth month in which at least one accident occurs.

Answers

Answer 1

To calculate the probability that there will be at least four accident in no accident occur before the forth month in which at least one accident occurs

If a month with one or more accidents is regarded as success and let the

k = the number of failures before the fourth success, and  then k follows a negative binomial distribution and the requested probability is

1. success taken as a month with no accident

2. k = the number of failure before the fourth success

Alternatively the solution is where [tex]Pr[k\leq 3][/tex]

which is derived directly as a negative binomial distribution

Therefore, the probability that there will be at least four months in which no accidents occur before the fourth month in which at least one accident occurs is 0.2898

A complex number is represented on a complex plane. The number [tex]z = 3-5i[/tex] is represented in a smilar manner as real numbers but y axis cosidered a imaginary axis.

What is a complex plane?

A complex plane is formed by complex numbers in a similar manner as the Cartesian coordinate system. But the x axis is made up of real numbers and y axis is made up of imaginary numbers.

A complex number is plotted on a complex plane. In the complex plane the x axis is known as the real axis and the y axis is known as the imaginary axis.

Consider the given complex number.

[tex]z = 3-5i[/tex]

Here, 3 is real number and -5 is imaginary number.

Since 3 is real number hence, move 3 steps in the right direction on x axis. Now, -5 is the imaginary number hence, move 5 steps in the downward direction parallel to the y axis.

The final position is [tex]z = 3-5i[/tex].  

Hence, a complex number is represented on a complex plane.

Hilary paints a wall in her bedroom that has two windows, as shown. What percent of the wall does she paint? Round your answer to the nearest whole percent, it necessary.

Answers

The percent of the wall does she paint will be;

⇒ 79%

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

The length of room wall = 8 feet

The width of room wall = 12 feet

The length of windows = 5 feet

The width of windows = 2 feet

Now,

The area of wall = 12 x 8 feet²

                         = 96 feet²

And, The area of windows = 5 x 2 feet²

                                         = 10 feet²

Hence, The area of paints a wall in her bedroom = 96 - 2 (10)

                                                                            = 96 - 20

                                                                            = 76 feet²

So, She paint the wall of area 76 feet².

Since, The area of whole wall = 96 feet²

But, There are two window.

So, The percent of only wall paint of are 76 feet² = 100 x 76 / 96

                                                                            = 79.16%

Thus, The percent of the wall does she paint to the nearest whole percent will be;

Show that Φ(u,v)=(7u+4,u−v,13u+v) parametrizes the plane 2x−y−z=8. Then: (a) Calculate Tu , Tv, and n(u,v). (b) Find the area of S=Φ(D), where D=(u,v):0≤u≤5,0≤v≤6. (c) Express f(x,y,z)=yz in terms of u and v and evaluate ∬sf(x,y,z)ds(a) Tu= , Tv= , n(u,v)=_______________(b) Area(S)=_______(c) ∬sf(x,y,z)ds=___________

Answers

Answer:

Step-by-step explanation:

1.Φ(u,v) gives the parametrization with its x, y, and z components. So, x=7u+4, y=u-v, and z=13u+v. We can use this to get the tangent vectors by taking the respective partial derivatives. Tu=<7, 1, 13> by taking the u derivatives of the components and Tv=<0, -1, 1> by taking the v derivatives of the components.

2. Taking the cross product of Tu and Tv will give the normal vector n(u,v), which is <14, -7, -7>

3. To find Area(S), you have to multiply the area of D by the magnitude of the normal vector from the previous step. D is the region defined by 0<=u<=5 and 0<=v<=6, so the area of D is 5*6=30. Multiply this by the magnitude of the normal vector to find that Area(S)=30sqrt(294)

4. To integrate, we first must put the initial function in terms of the parameters we found in the first step. Replace y with u-v and z with 13u+v. Next, multiply this integrand by the magnitude of the normal vector (sqrt294) and apply the given bounds for u (0<=u<=5) and v (0<=v<=6). From here the problem can be integrated like any other double integral, the final answer being 190sqrt(294)

Answers

The SI unit for density is kilogram per cubic meter (kg/m³)/

Kilogram Per Cubic Meter:

The SI unit for density is the kilogram per cubic meter (kg/m3). For many situations, however, this as an inconvenient unit, and we often use grams per cubic centimeter (g/cm3) for the densities of solids and liquids, and grams per liter (g/L) for gases.

According to the question:

Firstly, have to change your units to kilograms and cubic meters. Since there are a thousand grams in a kilogram,

                        170g = 1.70 x 10⁻¹ kg.

Since there are a thousand milliliters in a liter and a thousand liters in a cubic meter

               100ml = 1.00 x 10⁸ cubic meters

Therefore, Density= mass/volume

Answers

The evidence is not sufficient to support the claim since the p-value is 0.1833 higher than 0.05, so e) none of the preceding.

How to find p-value?

α = significance level = 0.05

n = sample size

df = degree of freedom = n - 1 = 10 - 1 = 9

Before we find the p-value, we use t test formula. But, before that we calculate mean and standard deviation for two population with excel.

In excel we get,

[tex]\bar x_1[/tex] = 231.8

[tex]\bar x_2[/tex] = 214.8

[tex]\sigma_1[/tex] = 41.95

[tex]\sigma_2[/tex] = 37.90

Next, we can calculate t test. So,

t = [tex]\frac{\bar x_1 -\bar x_2}{\sqrt{\frac{\sigma^2_1+\sigma^2_2}{n}}}[/tex]

= [tex]\frac{231.8-214.8}{\sqrt{\frac{41.95^2+37.9^2}{10}}}[/tex]

= [tex]\frac{17}{\sqrt\frac{3,196.2125}{10}}[/tex]

= 0.9509

Using t score to p-value calculator for 0.9509, we get p-value = 0.1833.

Thus, the p-value is 0.1833 is higher than significance level 0.05 so there is no sufficient evidence to support the claim.

The area of the triangle is 3 units² which has a hypotenuse of 3 units and a side of 2 units.

What is a triangle?

A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon.

There are three sides and three angles in every triangle, some of which may be the same.

In the case of a right triangle, the three sides are given unique names: the hypotenuse, which is the side that faces the right angle, and the legs, which are the other two sides.

Every triangle is bicentric and convex.

The triangle's interior is the area of the plane it encloses; the outside is the rest of the plane.

So, the area of the triangle will be:

We know that the hypotenuse is 3 units.

The length of the other side is 2 units.

Area of triangle formula: 1/2 * base * height

Now, insert values in the formula and calculate:

1/2 * base * height

1/2 * 2 * 3

3 units²

Therefore, the area of the triangle is 3units² which has a hypotenuse of 3 units and a side of 2 units.

Answers

Answer:41/60

Step-by-step explanation:

3/5 and 4/7 can also be expressed as 21/30 and 20/30 respectively.

(7 and 5 have a common multiple of 30) if you multiply both of these by 2/2 (aka 1) then you get 42/60 and 40/60 respectively.

In between these 2 fractions is 41/60.
