The constant of proportionality is 5

For the first bar day: 1 cell phone sold: 5 (unit rate:5)

second bar day: 2 cell phones sold: 10 (unit rate:5)

third bar Day: 3 cell phones sold: 15 (unit rate: 5)

fourth bar day: 4 cell phones sold: 20 (unit rate 5)

Basically you divide the cell phones sold by the day or $\frac{rise}{run}$

Hope this helped <3

The controller (money manager) for a small company puts some money in a bank account paying 5% per year. He uses some addition

zhuklara [117]

$x @ 4%, $x/3 @ 5% , $(10,000- 4x/3) @ 9%

.04x +.05x/3 + .09(10000 - 4x/3) = 729 

4x + 5x/3 + 9(10000 - 4x/3) = 72900 

19x/3 = 17100, x = 2700 
------------------ 
$2700 @ 4% 
$900 @ 5% 
$6400 @9%

SAT scores (out of 1600) are distributed normally with a mean of 1100 and a standard deviation of 200. Suppose a school council

fgiga [73]

Answer:

0.91517

Step-by-step explanation:

Given that SAT scores (out of 1600) are distributed normally with a mean of 1100 and a standard deviation of 200. Suppose a school council awards a certificate of excellence to all students who score at least 1350 on the SAT, and suppose we pick one of the recognized students at random.

Let A - the event passing in SAT with atleast 1500

B - getting award i.e getting atleast 1350

Required probability = P(B/A)

= P(X>1500)/P(X>1350)

X is N (1100, 200)

Corresponding Z score = $\frac{x-1100}{200}$

$P(X>1500)/P(X>1350)\\= \frac{P(Z>2)}{P(Z>1.25} \\=\frac{0.89435}{0.97725} \\=0.91517$
