First, sort the sumbers in order from the least value to the greatest value.

37, 45, 59, 67, 76, 68, 77, 78, 82, 82, 84, 84, 85, 85, 88, 90, 91, 91, 92, 92, 93, 95, 100, 100

There 24 scores listed. Divide 24 by 2 and you get 12.. Find the 12th number in the ordered list from the least value, which is the number 84. Find the 12th score in the ordered list from the large value, which is 85.
Because there are two central numbers, add the two central numbers and divide it by 2.

84+85=169
169/2=84.5

PLEASE HELP!!!!

Semmy [17]

You should put 4 as x, -3 as y and a as slope to make an equation :
$- 3 = a \times 4$
then you can find the slope and the correct equation of the line :

the slope is :
$- 3 = 4a \\ a = \frac{ - 3}{4}$
so the equation of the line will be
$y = \frac{ - 3}{4} x$
D is true
hope this helps

The angle of the elevation from the top of a 95 Todd building into a hot air balloon in the sky and 76° if the horizontal distan

AnnZ [28]

Answer:

The height of the hot air balloon is 1514.54 feet approximately.

Step-by-step explanation:

Consider the provided information.

The angle of elevation from the top of a 95-foot tall building to a hot air balloon in the sky is 76. If the horizontal distance between the building and the hot air balloon is 354 feet, find the height of the hot air balloon

The figure is shown below:

Let the height of the balloon is AD, the height of the building is BC.

Draw a line BE parallel to CD.

Therefore, AD=x+95, BC=95 and BE=CD=354 ft

Now in triangle $ABE$ .

$\tan\theta=\dfrac{\text{Opp}}{\text{Adj}}$

$\tan76^{\circ}=\dfrac{AE}{BE}$

$AE\approx 4.01\times 354$

$AE\approx 1419.54$

The height air balloon is 1419.54+95 =1514.54 ft

Hence, the height of the hot air balloon is 1514.54 feet approximately.

wolverine [178]

Answer:

1) $30,821 ( loan balance after 3 months in )

2) 8.56%

Step-by-step explanation:

Final Amount of compound interest: A = P ( 1 + i ) ^ n

p = principal = $30,000

r = interest rate = 11.41% = 0.1141

n = number of years

1) Loan balance after 3 months

n = 3/12 = 0.25 years

A = 30,000 ( 1 + 0.1141 ) ^ 0.25

= $30,821 ( loan balance after 3 months in )

2) Loan Balance after 1 year

A = 30,000 ( 1 + 0.1141 ) ^ 1

= $33423

interest on loan = 33423 - 30,000 = $3423

percentage of $40,000 is $3423

= 3423 / 40,000 * 100

= 8.56%

A 5.8-ft-tall person walks away from a 9-ft lamppost at a constant rate of 3.4 ft/sec. What is the rate that the tip of the pers

Dovator [93]

Answer:

9.56 ft/sec

Step-by-step explanation:

We are told that a 5.8-ft-tall person walks away from a 9-ft lamppost at a constant rate of 3.4 ft/sec.

I've attached an image showing triangle that depicts this;

Thus; dx/dt = 3.4 ft/sec

From the attached image and using principle of similar triangles, we can say that;

9/y = 5.8/(y - x)

9(y - x) = 5.8y

9y - 9x = 5.8y

9y - 5.8y = 9x

3.2y = 9x

y = 9x/3.2

dy/dx = 9/3.2

Now, to find how fast the tip of the shadow is moving away from the lamp post, it is;

dy/dt = dy/dx × dx/dt

dy/dt = (9/3.2) × 3.4

dy/dt = 9.5625 ft/s ≈ 9.56 ft/sec
