A length of chain is to be constructed by placing 36 component links end to end. The length of a link produced by a production p

Setler79 [48]

Answer:

d. 90 cm, 1.2 cm

Step-by-step explanation:

Given that:

The sample size n = 36

For the length of the link:

The mean $\overline x$ = 2.5

The standard deviation s = 0.2 cm

In a chosen 36 links, The mean and standard deviation for the length chain is as follows:

Mean = n $\overline x$

Mean = 36×2.5

Mean = 90 cm

The Standard deviation = s×√n

The Standard deviation = 0.2×√36

The Standard deviation = 0.2×6

The Standard deviation = 1.2 cm

The surface area of the three-dimensional figure is square centimeters?

Zina [86]

Answer:

Step-by-step explanation:

Alright, lets get started.

The surface area of the figure given is : The area of all shapes together

The figure has 2 similar triangles and 3 similar rectangles.

The area of 1 triangle =

$\frac{1}{2}*base*height$

The area of 1 triangle = $\frac{1}{2}*10*8.66=43.3$

So, the area of both triangles = $43.3*2=86.6$

The area of 1 rectangle = $width *length$

The of 1 rectangle = $10*15=150$

So, the area of all 3 rectangles = $3*150=450$

So, total area of figure = $86.6+450=536.6$

hence the surface area is 536.6 square centimeters : Answer

Hope it will help :)

Multiplying factors with exponents means you can add the exponents.

So $2^{4} \cdot 2^{-7} = 2^{4-7} = 2^{-3}$

A negative exponent becomes positive when you move it to the denominator, so:

$2^{-3} = \frac{1}{ 2^{3} }$
