Find the surface area of the cube shown below. units 2 2 squared
ruslelena [56]

The surface area of the cube with a side length of 2 units is 24 units squared

<h3>How to determine the surface area?</h3>

The side length of the cube is given as:

l = 2

The surface area is calculated as:

Surface area = 6l^2

This gives

Surface area = 6 *2^2

Evaluate

Surface area = 24

Hence, the surface area of the cube is 24 unit squared

What is the equation in slope intercept form of the line that passes through the point (2,-2) and is perpendicular to the line b
Gala2k [10]

Answer:

y= - 5/2x - 2

Step-by-step explanation:

Y=2/5x + 2

Making it perpendicular, the slope will change to it's reciprocal and swap operations (+ becomes -). 2/5 will be -5/2. We already know the y-intercept which is -2, so simply put, the equation in slope-intercept form is y = -5/2x - 2

Suppose you asked 100 commuters how much they spend each year and obtained a mean of $167 spent on transportation and a standard
Lena [83]

Answer:

The correct answer is "$159 and $175".

Step-by-step explanation:

The give values are:

Mean,

= $167

Standard deviation,

\sigma = $40

Number of commuters,

n = 100

Now,

⇒ SE=\frac{\sigma}{\sqrt{n} }

On putting the given values, we get

⇒       =\frac{40}{\sqrt{100} }

⇒       =\frac{40}{10}

⇒       =4

By using the 2 SE rule of thumb, we get

= $(167 - 2\times 4)

= 167-8

= 159 ($)

Or,

= (167 + 2\times 4)

= 167+8

= 175 ($)

i.e,

$159 and $175
