From her eye, which stands 1,61 meters above the ground, Savannah measures the
Cloud [144]

Answer:

152.99 m

Step-by-step explanation:

Using the solution diagram attached below :

We can obtain the height, h of skyscraper to the position of her eye level using trigonometry ;

Tan θ = opposite / Adjacent

Tan 24 = h / 340

h = tan 24 * 340

h = 151.37775

Hence, the height will be (h + distance from eyelevel to ground)

151.37775 + 1.61

= 152.98775

= 152.99 m

Use the information provided to write the equation of each circle​
Nadusha1986 [10]

Answer:

1.

centre(h,k)=(-13,9)

radius (r)=6

we have

equation of the circle is

(x-h)²+(y-k)²=r²

(x+13)²+(y-9)²=6²

x²+26x+169+y²-18y+81=36

x²+y²+26x-18y+169+81-36=0

x²+y²+26x-18y +214=0

is a required equation of the circle.

2.

centre(h,k)=(1,-1)

radius (r)=11

we have

equation of the circle is

(x-h)²+(y-k)²=r²

(x-1)²+(y+1)²=11²

x²-2x+1+y²+2y+1=121

x²+y²-2x+2y=121-2

x²+y²-2x+2y=119

is a required equation of the circle.

Sergio is working on a research project involving the ages of students at Brooklyn College. After interviewing 500 students, he
Zinaida [17]

Answer:

The probability of of a randomly chosen student being exactly 21 years old.

= 1.293

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given Population  size n = 500</em>

<em>Mean of the Population = 20 years and 6 months</em>

<em>                                        = </em>20 + \frac{6}{12} = 20 +0.5 = 20.5 years<em></em>

<em>Standard deviation of the Population = 2 years</em>

Let 'X' be the range of ages of the students on campus follows a normal distribution

Let   x =21

            Z = \frac{x-mean}{S.D}

            Z = \frac{x-mean}{S.D} = \frac{21-20.6}{2} =0.2

<em>The probability of a randomly chosen student being exactly 21 years old.</em>

<em>P( Z≤21) =  0.5 + A( 0.2) </em>

            = 0.5 +0.793

           =  1.293
