the equation a=1/2(b1+b2)h can be used to determine the area, a, of a trapezoid with height, h, and base lengths, b1 and b2. whi

galina1969 [7]

Answer:

b₁ = (2a – b₂h)/h; b₁ = (2a)/h – b₂; h = (2a)/(b₁ + b₂)

Step-by-step explanation:

A. Solve for b₁

a = ½(b₁ + b₂)h Multiply each side by 2

2a = (b₁ + b₂)h Remove parentheses

2a = b₁h + b₂h Subtract b₂h from each side

2a - b₂h = b₁h Divide each side by h

b₁ = (2a – b₂h)/h Remove parentheses

b₁ = (2a)/h – b₂

B. Solve for h

2a = (b₁ + b₂)h Divide each side by (b₁ + b₂)

h = (2a)/(b₁ + b₂)

The probability distribution for a

Tpy6a [65]

Answer:

$P(x \le -3) =0.30$

Step-by-step explanation:

Given

The attached probability distribution of x

Required

Find $P(x \le -3)$

To do this, we consider all values of x less than or equal to-3.

So, we have:

$P(x \le -3) =P(x=-5) + P(x = -3)$

From the table:

$P(x=-5) = 0.17$

$P(x = -3) = 0.13$

So, the equation becomes

$P(x \le -3) =P(x=-5) + P(x = -3)$

$P(x \le -3) =0.17 + 0.13$

$P(x \le -3) =0.30$
