a share of stock in the bree medical supply company is quoted at 35 1/4. suppose you hold 20 shares of that stock, which you bou

erica [24]

Total number of stocks bought = 20
Rate at which each stocks were bought = 31 1/2
   = 63/2
Rate at which 20 stocks were bought = 20 * (63/2) dollars
   = 10 * 63 dollars
   = 630 dollars
Rate at which each stocks were sold = 35 1/4
   = 141/4 dollars
Rate at which 20 stocks were sold = 20 * (141/4) dollars
   = 5 * 141 dollars
   = 705 dollars
Then
Amount of profit made by selling 20 stocks = (705 - 630) dollars
      = 75 dollars
So the total amount of profit made is $75. The correct option in regards to the given question is option "D".

I NEED HELP!!!!!In the graph shown, suppose that f(x) = 3.5x and h(x) = 1.5x. Choose the statement that COULD be true.

rusak2 [61]

The given functions are

$f(x)=3.5^x$

$h(x)=1.5^x$

Now these are exponential curves and the bases for the functions are 3.5 & 1.5

Also the graph of g(x) is between f(x) & h(x)

Hence the value of base called the scale factor must be between 3.5 & 1.5.

4 & 5 are more than 3.5

0.9 is smaller than 1.5

But π = 3.14 lies between 3.5 & 1.5.

Hence the only option which can represent the graph of g(x) is

$g(x)=\pi ^x$

Option D) is the right answer

What’s the answer to 6x + 3y =

Alex73 [517]

Answer:

The last answer; 12.

Step-by-step explanation:

In order to solve this, use substitution. Since it gives you an equation for y, substitute that equation in the other formula as y. This will give you:

$6x+3(-2x+4)=?$

Then simplify:

$6x-6x+12=?$

Since 6x - 6x cancels out, you are left with 12.

$?=12\\$

A new gas- and electric-powered hybrid car has recently hit the market. The distance traveled on 1 gallon of fuel is normally di

Doss [256]

Answer:

a) P [ Z > 70 ] = 0.1075 or 10.75 %

b) P [ Z < 60 ] = 0.1038 or 10.38 %

c) P [ 55 ≤ Z ≤ 70 ] = 0.8882 or 88.82 %

Step-by-step explanation:

Normal Distribution μ = 65 and σ = 4

a) The probability of the car travels more than 70 miles per gallon is:

P [ Z > 70 ] = (Z-μ) ÷ σ ⇒ P [ Z > 70 ] = (70-65) ÷4 P [ Z > 70 ] = 1.25

the point 1.25 corresponds at values, from left tail up to 70 so we must go and look for the area for the point 1.24 which is 0.8925. Then we have the area or probability of all cars traveling up to 70 miles therefore we have to subtract 1 -0,8925

P [ Z > 70 ] = 0.1075 or 10.75 %

b)The probability of the car travels less than 60 miles per gallon is:

P [ Z < 60 ] = ( 60 - μ ) ÷ σ ⇒ P [ Z < 60 ] = (60-65)÷ 4 P [ Z < 60 ] = -1.25

Again -1.25 corresponds to 60 miles per gallon threfore we move to the left and find for point -1.26 which area is 0.1038 so

P [ Z < 60 ] = 0.1038 10.38 %

c) P [ 55 ≤ Z ≤ 70]

For point Z = 70 or 1.25 (case a above) P [ Z ≤ 70] = (70-65)÷4

P [ Z ≤ 70] = 1.25

In this case we got the whole area from the left tail up to 1.25

P [ Z ≤ 70] = 0.8944 (includes the area of the point from the left tail up to the point assocciated to 55 miles and for that reason we have to subtract that area)

P [ Z ≥ 55 ] = (55-65) ÷ 4 P [ Z ≥ 55 ] = -2.5 and the area is 0.0062

So P [ 55 ≤ Z ≤ 70 ] = 0.8944 - 0.0062 = 0.8882
