Answer:

Yes, they are proportional.

Step-by-step explanation:

Using this from what I found helped me answer the question, and if you compare their ratios, they are both going to show that 75% each class have texted:

Proportional: When quantities have the same relative size. In other words they have the same ratio.

All you would have to do is compare the amount of students that texted(x) to the amount of students there are total in the class(y). When you compare them in a y:x format, it will all lead up to the results showing that 75% of both groups have texted.

Answer:

$863

Step-by-step explanation:

Given: Carla Arslanian is 55 years old. She wants to purchase a $100,000, 10-year term life insurance policy.

To find: What is her annual premium?

Solution: Insurance companies use mathematical calculation and statistics to calculate the number of insurance premiums they charge their clients.

Annual premium = face value x rate $100

Annual premium (for building) = $100,000 ÷ $1000 x 10 = $1000.  

The sum of the annual premium is $863.

PLEASE I NEED THIS ASAPPP I NEED THIS TODAY
olganol [36]

Answer:

Step-by-step explanation:

-16x^2 + 24x + 16 = 0.

A. Divide by 8:

-2x^2 + 3x + 2 = 0, A*C = -2*2 = -4 = -1 * 4. Sum = -1 + 4 = 3 = B, -2x^2 + (-x+4x) + 2 = 0,  

(-2x^2-x) + (4x+2) = 0,  

-x(2x+1) + 2(2x+1) = 0,

(2x+1)(-x+2) = 0, 2x+1 = 0, X = -1/2. -x+2 = 0, X = 2.

X-intercepts: (-1/2,0), (2,0).  

B. Since the coefficient of x^2 is negative, the parabola opens downward. Therefore, the vertex is a maximum.

Locate the vertex: h = Xv = -B/2A = -24/-32 = 3/4, Plug 3/4 into the given Eq to find k(Yv). K = -16(3/4)^2 + 16(3/4) + 16 = 19. V(h,k) = V(3/4,19).

C. Choose 3 points above and below the vertex for graphing. Include the points calculated in part A which shows where the graph crosses the x-axis.

Help me find the approximate <br> area of the figure!!!
sukhopar [10]

Answer:

64.3 m²

Step-by-step explanation:

The figure is composed of a square and a quarter circle.

Therefore, area of the figure = area of the square + area of quarter circle

= s² + ¼(πr²)

Where,

s = 6 m

r = 6 m

Plug in the values

Area = 6² + ¼(π*6²)

Area = 64.274334 ≈ 64.3 m² (nearest tenth)
