Mars 100 * 56.55/150 = 37.7% 
<span>Moon 100 * 24.9/150 = 16.6% (about 1/6, remember that) </span>

<span>Mars .377 x </span>
<span>Moon .166 x </span>

<span>.166 * 180 = 29.9 pounds (note 180/6 =30) </span>

<span>180 * 2.364</span>

aksik [14]

Answer:

2.5x+0.75y=933

x+y=747

Step-by-step explanation:

x= number of cheese sandwiches

y= number of soft drinks

first equation: 2.5x+0.75y=933

**this is representing the cost of the drinks and sandwiches

second equation: x+y=747

**because x and y are the NUMBER of soft drinks and sandwiches, they both have to toal up to 747.

The life expectancy (in hours) of an electric bulb is normally distributed with a mean of 5000 and a standard deviation of 1000.
Sergeu [11.5K]

Answer:

P(z>1.3) = 0.9032

Step-by-step explanation:

We are given:

Mean = 5000

Standard deviation = 1000

x = 6300

P(x>6300)=?

z-score =?

z-score = x- mean/standard deviation

z-score = 6300 - 5000/1000

z- score = 1300/1000

z-score = 1.3

So, P(x>6300) = P(z>1.3)

Looking at the z-probability distribution table and finding value:

P(z>1.3) = 0.9032

So, P(z>1.3) = 0.9032

In a graphing program, graph the following 4 functions in the same coordinate plane.
9966 [12]

See below for the changes when the exponential function is transformed

<h3>How to determine the effect of a</h3>

The exponential functions are given as:

y = \sqrt x

y = 5\sqrt x

y = 14\sqrt{x

y = -2\sqrt{x

An exponential function of the above form is represented as:

y = a\sqrt{x

See attachment for the graph of the four functions.

<u>When a is large</u>

This is represented by y = 14\sqrt{x

In this case, the curve of the base form y = \sqrt x is vertically stretched and it moves closer to the y-axis

<u>When a is small</u>

This is represented by y = 5\sqrt x

In this case, the curve of the base form y = \sqrt x is vertically stretched and it moves away from the x-axis

<u>When a is negative</u>

This is represented by y = -2\sqrt{x

In this case, the curve of the base form y = \sqrt x is vertically stretched and is reflected across the y-axis.
