Answer:

The value is  [tex]P(O) = 0.3481[/tex]

Step-by-step explanation:

From the question we are told that  

   The  proportion of people that own a dog is [tex]p = 0.59[/tex]

Generally the probability of the two selected people owning a dog is mathematically evaluated as

      [tex]P(O) = p^2[/tex]

      [tex]P(O) = (0.59 )^2[/tex]

      [tex]P(O) = 0.3481[/tex]

Answer:

plane EHV

Step-by-step explanation:

To find the other name of plane T, we have to find any three non-collinear points on the plane T.

It means we have to find any three points which lie on the plane T but in a single straight line.

From the given figure it is clear that points E, H and V lie on plane T and they are not collinear.

Therefore, the other name of plane T is plane EHV.

Note: There are many other possible names of plane T, EHV is one of them.

Answer:

The height h it will travel in t minutes

Height h = 6 + 20(t)

Oh=20t + 6

Step-by-step explanation:

A hot air balloon starts at a height of 6 feet above the ground and then rises at a rate of 20 feet each minute.

Initial height h0 = 6 feet

Then it travel 29 feet each minute

Rate = 20 feet/ minute

The height h it will travel in t minutes

Height h = 6 + 20(t)

Answer:

The  points are

        [tex]t_1 =  0.7433[/tex]

        [tex]t_2 = -0.299[/tex]

Step-by-step explanation:

From the question we are told that

   The  first equation is  [tex]x(t) = 3t^3 -2t^2-2t -4[/tex]

     The second equation is  [tex]y(t) =  3t^2 -2t -2[/tex]

Now differentiating the first and second equation

        [tex]\frac{dx(t)}{dt} =  9t^2 -4t-2[/tex]

and

      [tex]\frac{dy(t)}{dt} =  6t-2[/tex]

Now

     [tex]\frac{dy(t)}{dx(t)}  =  \frac{\frac{dy(t)}{dt} }{\frac{dx(t)}{dt} } = \frac{9t^2 -4t-2}{6t-2}[/tex]

at critical point

     [tex]\frac{dy(t)}{dx(t)}  = 0[/tex]

=>   \frac{9t^2 -4t-2}{6t-2}=0[/tex]

=>   [tex]9t^2 - 4t-2 = 0[/tex]

solving using quadratic formula we have that

     [tex]t_1 =  0.7433[/tex]

and [tex]t_2 = -0.299[/tex]

Answer:

Hey!

Your answer is 123,500!

Step-by-step explanation:

TO ROUND TO THE NEAREST HUNDRED we need to look at the TENS column...

IN THIS CASE WE LOOK AT '5'...

If its bigger than 4 INCREASE THE DIGIT IN THE HUNDREDS PLACE BY ONE

If its smaller than 5 DECREASE THE DIGIT IN THE HUNDREDS PLACE BY ONE!

So as 5 is a digit that makes us ROUND UP...we change 4 to a 5 to have 123,500 as our answer!

Answer: $107,836.69 or about $107,837 (to the nearest dollar)

Step-by-step explanation:

Formula to the  accumulated amount received after investing principal amount (P) at rate of interest (r) compounded monthly for t months :

[tex]A=P(1+\dfrac{r}{12})^{t}[/tex]

As per given , A = $130,000

r= 7.5% = 0.075

t= 30 months

Now,

[tex]130000=P(1+\dfrac{0.075}{12})^{30}\\\\\Rightarrow 130000=P(1+0.00625)^{30}\\\\\Rightarrow 130000=P(1.00625)^{30}\\\\\Rightarrow 130000=P \times1.20552661036\\\\\Rightarrow\ P=\dfrac{130000}{1.2055266}=107,836.69[/tex]

Hence he need to invest $107,836.69 .

Answer:

The answer is B: $29.35x + $17.45y

Step-by-step explanation:

The frequency and the time period is related by the formula as follows :

[tex]f=\dfrac{1}{T}[/tex]

Here, f is frequency and T is time period

Now, we need to solve T in terms of f.

Firstly, cross multiplying the above equation,

[tex]f\times T=1[/tex]

Now dividing both sides by T.

[tex]\dfrac{f\times T}{T}=\dfrac{1}{T}\\\\f=\dfrac{1}{T}[/tex]

Hence, this is the required solution.

Answer:

T= 1/f

Step-by-step explanation:

T= one OVER f

Answer: Answer is the steps

Step-by-step explanation:

Step 1:  Richie rewrite the equation as 24x + 18(x-2) =216

Step 2: Richie  applied the distributive property to eliminate the parentheses  and got the equation  24x + 18x - 32 = 216

Step 3: Richie combine like terms  to get the equation 42x -36 =216

Step 4: Richie added 36 to both sides to get the new equation 42x = 252  

Richie was not done solving for x so in

Step 5: Richie should have divided both sides by 42 to get  the final answer

x = 6.

In mathematics, counterexamples are often used to prove the boundaries of possible theorems. By using counterexamples to show that certain conjectures are false, mathematical researchers avoid going down blind alleys and learn how to modify conjectures to produce provable theorems.

Answer:

7th measurement = -26

Step-by-step explanation:

The sequence is 16, 9, 2, –5, ...,

First term( a)= 16

Second term=9

Common difference (d) = 9-16

Common difference= -7

The sequence is a arithmetic progression

For AP's ,the terms formula is

Term(n) = a + (n-1)d

Where n represent the term to be found

In this case,we Are looking for the 7th term , so n= 7

Term(7) = 16+ (7-1)-7

Term(7)= 16 +6(-7).

Term (7) = 16-42

Term(7) = -26

7th term =-26

Answer:

[tex]900+20+7[/tex]

Step-by-step explanation:

Write 927 as a mathematical expression in expanded form.

So we see the number 927. It has hundreds, tens, ones. So the only thing we have to do it separate the number by hundreds, tens, ones. So now, let's start!

Hundreds: [tex]900[/tex]

Tens: [tex]20[/tex]

Ones: [tex]7[/tex]

We have 900, 20, and 7. Let's try adding them up to make 927.

[tex]900+20+7[/tex]

[tex]=927[/tex]

This is how we do 927 in expanded form.

Answer:

Section lines

Step-by-step explanation:

Sectioning is the process of cutting a surface by an imaginary plane, the view of the surface that is cut is shown in the section view.

Section lines are used to indicate where an imaginary cutting plane cuts a material. The imaginary cut is then represented using section lines which are usually thin, crosshatched.

Section lines shows the surface that have been cut by the cutting plane. There are different ways of sectioning such as full section, half section, off set section and so on

Answer:

  4(1000) +11(100) + 24(10,000) +11(1000) = 256,100

Step-by-step explanation:

Maybe you want to add 4000 +1100 to 24(10,000) +11,000.

1 thousand = 10 hundreds, so 4000 = 40 hundreds

  4000 +1100 = (40 +11) hundreds = 51 hundreds

__

1 ten-thousand = 10 thousands, so 24(10,000) = 240 thousands

  24(10,000) +11,000 = (240 +11) thousands = 251 thousands

__

So, we want to add 251,000 and 51 hundreds. The latter can be considered to be 5000 +100, so we have ...

  251,000 +5100 = 251,000 +5,100 = (251 +5) thousands + 1 hundred

  = 256,100

Hey There!! ☄️ The general vertex to The general vertex form is this:

v(x) = a (x-h)2 + k

and a indicates the widening or shrinking of the function compared to another parabolic function. If a become bigger, the graph becomes narrower. If a becomes negative, the graph is reflected over the x-axis.

Comparing f(x) = x2 with g(x) = -3(x+6)2 + 48, we have the following transformations:

The graph is reflected over the x-axis

The graph is made narrower.

The graph is shifted 6 units to the left.

The graph is shifted 48 units up.
