BAC ~ DEC<br><br>x = ___ units​
sergey [27]

Given:

\Delta BAC\sim \Delta DEC

To find:

The value of x.

Solution:

We have,

\Delta BAC\sim \Delta DEC

The corresponding parts of similar triangles are proportional.

\dfrac{AB}{ED}=\dfrac{AC}{EC}

On substituting the values, we get

\dfrac{24}{56}=\dfrac{2x}{3x+5}

\dfrac{3}{7}=\dfrac{2x}{3x+5}

3(3x+5)=2x(7)

9x+15=14x

Subtract 9x from both sides.

15=14x-9x

15=5x

\dfrac{15}{5}=x

3=x

Therefore, the value of x is 3 units.

y - 5 = -8/7(x + 3)

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition

  • Left to Right

<u>Algebra I</u>

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Point-Slope Form: y - y₁ = m(x - x₁)  

  • x₁ - x coordinate
  • y₁ - y coordinate
  • m - slope

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-3, 5)

Point (2, -3)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

  1. Substitute [SF]:                    m=\frac{-3-5}{2+5}
  2. Subtract/Add:                      m=\frac{-8}{7}

<u>Step 3: Write Equation</u>

<em>Plug in variables into the general form.</em>

y - 5 = -8/7(x + 3)

y + 3 = -8/7(x - 2)

Assume that a procedure yields a binomial distribution with a trial repeated n times. Use the binomial probability formula to fi
irinina [24]

Answer:

0.2210

Step-by-step explanation:

If p = 0.04

then 1-p = 1 - 0.04 = 0.96

So we have the probability distribution value

as;

n C r * p^r * (1-p)^(n-r)

Thus;

64 C 3 * p^3 * (1-p)^(64-3)

= 64 C3 * 0.04^3 * 0.96^61

where 64 C 3 is 64 combination 3

= 41,664 * 0.04^3 * 0.96^61

= 0.2210
