Answer:

97.2 m³

Step-by-step explanation:

The volume of a triangular prism is half the volume of a rectangular prism with the same length, width, and height.

V = 1/2LWH

V = 1/2(9 m)(7.2 m)(3 m) = 97.2 m³

<em>Additional comment</em>

The relation we used above comes from the more general formula for the volume of a prism:

V = Bh

where B is the area of the base.

You know a rectangular base will have an area of ...

A = bh

and a triangle with the same base and height will have an area of ...

A = 1/2bh

That is, the base area of a triangle is half that of a rectangle with the same dimensions. When we use this fact in the volume formula, we find the volume of a triangular prism is 1/2 that of a rectangular prism with the same length, width, and height.

The correct answer is 5. This is because rate of change of a function or a line is its gradient. As we can see that the line is horizontal then the gradient must be equal to zero too.

On the other hand the equation is written in the form of y = mx + c where m is the gradient or slope and c is the y intercept so the gradient is equal to 5 if we match the places. So it is 5 times greater.

The lifetime of a certain type of battery is normally distributed with mean value 11 hours and standard deviation 1 hour. There

victus00 [196]

Answer: The required lifetime value is 11.27.

Step-by-step explanation:

Since we have given that

Mean value = 11 hours

Standard deviation = 1 hour

The total lifetime of all batteries in a package exceeds that value for only 5% of all packages.

So, α = 0.95, z= 1.645

n = 9

So, the lifetime value would be

$x=\mu+z\times \dfrac{\sigma}{\sqrt{n}}\\\\x=11+1.645\times \dfrac{1}{\sqrt{36}}\\\\x=11+1.645\times \dfrac{1}{6}\\\\x=11.27$

Hence, the required lifetime value is 11.27.

Suppose the number is y >>>>>So y/2 +2y/3 <14
multiply both sides by 6>>>>>>>>>. 6y/2 +6x2y/3 <14x6
3y + 4y < 84
7y <84
y <84/7
y < 12
