A supply curve for a product is the number of items that can be made available at different prices. A manufacturer of toy trucks

frutty [35]

Answer:

y = 400x - 1200

Step-by-step explanation:

considering the linear equation y = mx + c

where y denotes number of items

x denotes item price

we have y = 2000 and x = $8 so we have now

2000 = m(8) + c ...... 1

now we have

y = 400 and x = $4

400 = m(4) + c .....2

from equation 1 and 2 we have

subtracting 2 from 1

1600 = 4m

m = 400

solving for c value

400 = 4m + c

400 = 4*400 + c

c = -1200

y = 400x - 1200

Zigmanuir [339]

We are tasked to solve for the median of the doctor's patients during the last 7 days that he was on duty. The given numbers are the following:
24, 27, 31, 19, 26, 15 and 19

Solving for the median, we have:
Median = (24 + 27 + 31 + 19 + 26 + 15 + 19) / 7 days
Median = 23

The median is 23.

where r is radius and h is height.

Here given radius = 5 and height = 3

Using the formula: πr²h

: π * 5² * 3

: π * 5 * 5 * 3

: 75π or 235.62 cm³

Ngoc invests a total of $11,000 in two accounts paying 5% and 7% simple interest, respectively. How much was invested in each ac

Rama09 [41]

Answer:

At 5% amount invested = $7,500

At 7% amount invested = $3,500

Step-by-step explanation:

We shall create an equation for this.

Let the amount invested with 5 % interest = "x"

Then remaining amount = 11,000 - x, Since total amount invested = $11,000

(x $\times$ 5%) + ((11,000-x) $\times$ 7%) = $620

0.05 x + 770 - 0.07 x = 620

770 - 620 = 0.07 x - 0.05 x

150 = 0.02 x

$\frac{150}{0.02}$ = x

$7,500 = x

Therefore, amount invested at 5% = $7,500

At 7% = $11,000 - $7,500 = $3,500
