The summer monsoon rains bring 80% of a country's rainfall and are essential for the country's agriculture. Records going back m

ore than a century show that the amount of monsoon rainfall varies from year to year according to a distribution that is approximately Normal with mean 856 millimeters (mm) and standard deviation 89 mm. Use the 68-95-99.7 rule to answer the following questions.
Between what values do the monsoon rains fall in 95% of all years?

How small are the monsoon rains in the driest 2.5% of all years?

Solve the systems by the addition method x - 2y = - 4 2x + y = 7
vfiekz [6]
<h2>x - 2y = -4</h2><h2>2x + y = 7</h2><h2 />

To solve this system of equations by addition, our first goal is to cancel

out one of the variables by adding the two equations together.

However, if we add these two equations together right away, nothing

will cancel so we need to set things up so a variable will cancel.

Notice that we have an 2x in our second equation.

If we had a -2x in our first equation, then the x's would cancel out.

In order to create a -2x in the first equation, we simply

multiply both sides of the first equation by -2.

So we have (-2)(x - 2y) = (-4)(-2) which can be rewritten as -2x + 4y = 8.

Now rewrite both equations, as shown below.

<h2>-2x + 4y = 8</h2><h2>2x + y = 7</h2><h2 />

Now when we add the equations together, the x terms

will cancel out and we're left with 5y = 15.

Dividing both sides by 5, <em>y = 3</em>.

To solve for x, plug a 3 in for y in either one of our 2 original equations.

So let's go with our second equation.

Plugging a 3 in for y, we get 2x + (3) = 7.

Now subtract 4 from both sides to get 2x = 4.

Dividing both sides by 2, we fid that <em>x = 2</em>.

Since x = 2 and y = 3, our answer is the ordered pair (2, 3).

Minchanka [31]

Answer:

This statement makes sense because this would mean that a slice of pizza and a soda costs him about ​$49 a day

Step-by-step explanation:

Given

The total spent on a slice of pizza and a soda is:

Cost > \$18000 per year

Required

Which of the options is true:

First, we calculate the daily amount spent on a slice of pizza and a soda.

Assume that the yearly cost is: $18000

The daily cost is:

Daily = \frac{\$18000}{365}

Daily = \$49.32

This means that he spends about $49 daily
