A newspaper stand sold 1,000 copies of the city newspaper for $1,600 write and solve an equation to find the price of one copy

Vsevolod [243]

Answer: $\$1.6$

Step-by-step explanation:

Let be "x" the price in dollars of one copy of the city newspaper.

You need to analize the information provided in the exercise:

1. The total number of copies of the city newspaper sold in the newspaper stand is:

$Total\ copies=1,000$

2. The amount of money earned by selling 1,000 copies of the city newspaper is:

$Total\ earned=\$1,600$

Then, you can determine that the value of "x" can be found with:

$x=\frac{Total\ earned}{Total\ copies}$

3. Finally, substituting values, you get:

$x=\frac{\$1,600}{1,000}\\\\x=\$1.6$

Which of the following coordinate points is the point of intersection of these two lines? y - 6x = -4 and y - 2x = 8

Nimfa-mama [501]

Answer:

(x,y)=(3,14)

Step-by-step explanation:

y-6x=-4 , y=-4+6x

y-2x=8, y=8+2x

(y=)-4+6x=8+2x

6x-2x=8+4

4x=12

x=12/4

x=3, then

y=-4+6*3=-4+18=14

(x,y)=(3,14)

Find the probability of the indicated event if P(E) = 0.25 and P(F) = 0.40.

Wewaii [24]

Answer:

$P(E\ or\ F) = 0.60$

Step-by-step explanation:

Given

$P(E) = 0.25$

$P(F) = 0.40$

$P(E\ and\ F) = 0.05$

Required

Determine P(E or F)

This is calculated using:

$P(E\ or\ F) = P(E) + P(F) - P(E\ and\ F)$

$P(E\ or\ F) = 0.25 + 0.40 - 0.05$

$P(E\ or\ F) = 0.60$
