You design the wooden picture frame and paint the front surface.
Hitman42 [59]

Answer:

  • a) 8x + 28
  • b) 68 in²

Step-by-step explanation:

a)

<u>Area of the frame with picture:</u>

  • A = lw
  • A₁ = (x + 4)(x + 7) = x² + 11x + 28

<u>Area of the picture:</u>

  • A₂ = x(x + 3) = x² + 3x

<u>Area of the wooden frame is the difference of the above values:</u>

  • A₃ = A₁ - A₂
  • A₃ = x² + 11x + 28 - x² - 3x
  •     = 8x + 28

b)

<u>When x = 5, the picture frame area is:</u>

  • A₃ = 8*5 + 28 = 40 + 28 = 68 in²

We will be using the binomial probability formula to solve the problem

The formula is given by ⁿCₓ (p)ˣ (1-p)ⁿ⁻ˣ

Where:
n = the number of trials = 100
x = the number of samples we are trying on = 3
p = the probability of success = 2% = 0.02

We can either calculate ⁿCₓ by using the scientific calculator using the ^nC_r button or by doing it manually use \frac{n!}{(n-x)!x!}

P(3) = ¹⁰⁰C₃ (0.02)³ (1 - 0.02)¹⁰⁰⁻³
P(3) = ¹⁰⁰C₃ (0.02)³ (0.98)⁹⁸
P(3) = 0.182 (rounded to three decimal places)

Correct answer: option 3

Sloane kicked a soccer ball off the ground at a speed of 56 feet per second. the height of the ball can be represented by the fu
ycow [4]

The time in seconds that it took the ball to travel would be = 0.25 seconds.

<h3>Calculation of speed time</h3>

Speed can be defined as the distance covered by an object per unit time.

The speed used to kick the soccer off the ground = 56 feet per second.

The height equation= −16t² + 56t

The time= ?

The formula for speed = distance/time

56= −16t² + 56t/t

56t = −16t² + 56t/t

−16t² = -56t + 56t

−16t² = 0

Make t the subject formula,

t = √1/16

t = 0.25 seconds.
