If 80% is 72 marks, what is full marks?

zysi [14]

$Use\ a\ proportion:\\\begin{array}{ccc}80\%&-&72\\100\%&-&x\end{array}\ \ \ |cross\ multiply\\\\\\80\cdot x=72\cdot100\\80x=7,200\ \ \ |diviede\ both\ sides\ by\ 80\\\boxed{x=90}\leftarrow your\ answer$

Estimate the answer to 44,596,251 – 28,257,934 by first rounding each number to the nearest million.

pickupchik [31]

Estimate
44,596,251 = 45,000,000
28,257,934 = 28,000,000

45,000,000 - 28,000,000 = 17,000,000

answer
17,000,000

Fast food restaurants pride themselves in being able to fill orders quickly. A study was done at a local fast food restaurant to

s344n2d4d5 [400]

Answer:

$\left \{ {{0.667 e^{-0.6667 x}, x \geq 0} \atop {0, x < 0}} \right$

Step-by-step explanation:

The probability density function for the exponential distribution is:

$\left \{ {{\mu e^{-\mu x}, x \geq 0} \atop {0, x < 0}} \right$

In which $\mu = \frac{1}{m}$ is the decay parameter and m is the mean.

It was discovered that the time it takes for orders to be filled is exponentially distributed with a mean of 1.5 minutes.

This means that $m = 1.5, \mu = \frac{1}{1.5} = 0.6667$

So, the answer is:

$\left \{ {{0.667 e^{-0.6667 x}, x \geq 0} \atop {0, x < 0}} \right$
