Stock prices fell 250 points one day and 60 points the next day. What is the average change in stock prices over the two days

arsen [322]

Answer:

the average change in stock prices over the two days is -155

Step-by-step explanation:

The computation of the average change in stock price over the two days is shown below:

= (-One day points - second day points) ÷ number of days

= (-250 points - 60 points ) ÷ 2 days

= -310 points ÷ 2 days

= -155

Hence, the average change in stock prices over the two days is -155

We simply applied the above formula so that the average change could come

We know that there was $5 left over, so we can set up an equation to solve for the price per water bottle:

$50 - 10x = 5\\-10x = -45\\x = 4.50$

Each water bottle cost $4.50

he width and length of a rectangle (in feet)are consecutive odd integers. If the length is increased by 5 feet, the area of the

Ivanshal [37]

The original area of the rectangle is $35ft^{2}$

<u>Explanation:</u>

width = x

length = x + 2

area of the rectangle = x (x+2)

length = x + 2 + 5 = x+7

$60 = (x+7) (x)\\60=x^{2} + 7x\\x^{2} + 7x - 60 =0\\$

Solving this equation, we get

x =5ft

So, original width = 5ft

original length = 5+2ft = 7ft

Thus, original area of the rectangle = 5 X 7ft = $35ft^{2}$

Therefore, the original area of the rectangle is $35ft^{2}$

Harlene tosses two number cubes. If a sum of 8 or 12 comes up, she gets 9 points. If not, she loses 2 points. What is the expect

Amanda [17]

P(8 or 12) = 1/6
P(not 8 or 12 = 5/6
Let the expected points fro one roll be X.
$E(X)=9\times\frac{1}{6}-2\times\frac{5}{6}=-\frac{1}{6}\ points$
The answer is -(1/6) points.
