Answer:

The coefficient of x is 8

Step-by-step explanation:

Given

P = 2(x+8) + 2(3x) --- Perimeter

Required

Determine the coefficient of x

P = 2(x+8) + 2(3x)

Open bracket

P = 2x + 16 + 6x

Collect like terms

P = 2x + 6x+ 16

P = 8x+ 16

<em>The coefficient of x is 8</em>

X 6.4.5-T
butalik [34]

Same strategy as before: transform <em>X</em> ∼ Normal(76.0, 12.5) to <em>Z</em> ∼ Normal(0, 1) via

<em>Z</em> = (<em>X</em> - <em>µ</em>) / <em>σ</em>   ↔ <em>X</em> = <em>µ</em> + <em>σ</em> <em>Z</em>

where <em>µ</em> is the mean and <em>σ</em> is the standard deviation of <em>X</em>.

P(<em>X</em> < 79) = P((<em>X</em> - 76.0) / 12.5 < (79 - 76.0) / 12.5)

… = P(<em>Z</em> < 0.24)

… ≈ 0.5948
