Answer:

A =42 in^2

Step-by-step explanation:

This is a trapezoid

The area of a trapezoid is found by

A = 1/2(b1+b2)h where b1 and b2 are the lengths of the bases

A = 1/2(13+8) *4

A =42 in^2

It would be: 5/17 * 3/8 = 5*3 / 17*8 = 15/136

In short, Your Answer would be 15/136

Hope this helps!

When you have

$4x=\dfrac{2}{5}$

you can solve the equation by multiplying both sides by 1/4. Then simplify.

$4x\cdot\dfrac{1}{4}=\dfrac{2}{5}\cdot\dfrac{1}{4}\\\\x\cdot\dfrac{4}{4}=\dfrac{2\cdot 1}{5\cdot 4}\\\\x=\dfrac{2}{20}=\dfrac{1}{10}$

A certain chalkboard manufacturer determines that their largest blackboard model has a mean length of 5.00 m and a standard devi

Igoryamba

Answer:

23 chalkboards

Step-by-step explanation:

Given:

Mean length = 5 m

Standard deviation = 0.01

Number of units ordered = 1000

Now,

The z factor = $\frac{\textup{x - Mean}}{\textup{standard deviation}}$

The z factor = $\frac{\textup{4.98 - 5}}{\textup{0.01}}$

Z = - 2

Now, the Probability P( length < 4.98 )

Also, From z table the p-value = 0.0228

therefore,

P( length < 4.98 ) = 0.0228

Hence, out of 1000 chalkboard ordered (0.0228 × 1000) = 23 chalkboard are likely to have lengths of under 4.98 m.
