The manufacturer of a laser printer reports the mean number of pages a cartridge will print before it needs replacing is 12,200.

Svetllana [295]

Answer:

14110

Step-by-step explanation:

Let x = number of pages ;

μ = 12200 ; σ = 820

Zscore = (x - μ) / s

Zscore = (x - 12200) / 820

Zcritical at 99% confidence, for a 1 - tail test is 2.33

Hence, Z at 99% = 2.33

Put Zscore = 2.33

Zscore = (x - 12200) / 820

2.33 = (x - 12200) / 820

2.33 * 820 = x - 12200

1910.6 = x - 12200

1910.6 + 12200 = x

x = 14110.6

x = 14111

The number of pages the manufacturer should advertise is 14,110

Answer:

Coordinates of A': will NOT be the same

Coordinates of C': will NOT be the same

Perimeter of ABC: will be the same

Area of A'B'C': will be the same

Measure of ∠B: will be the same

Slope of A'C': will be the same

Step-by-step explanation:

We have a triangle ABC that will be translated (moved) 2 units down, 3 units to the right.

Since the triangle is moved, then the coordinates of every summit (A, B and C) will be affected. So,

Coordinates of A': will NOT be the same

Coordinates of C': will NOT be the same

However, since the triangle is only moved, not transformed in any way, not scaled up/down for example the following will remain the same:

Perimeter of ABC: will be the same

Area of A'B'C': will be the same

Measure of ∠B: will be the same

Since the triangle is only translated, not rotated or reflected the following will remain the same:

Slope of A'C': will be the same

Find the slope of the line of (4,3) (1,-4)

deff fn [24]

Answer: -7/-3.

Step-by-step explanation: In this problem we're asked to find the slope of the line that passes through the points (4,3) and (1,-4).

Using our slope formula, we take the second y minus the first y which in this case is -4 - 3 over our second x minus our first x which in this case is 1 - 4.

-4 - 3 is -7 and 1 - 4 is -3.

So the slope of this line is -7/-3.

ahrayia [7]

Answer:

$1.65

Step-by-step explanation:

The total purchase can be described by ...

4(2h +1.25) = 18.20 . . . . where h is the price of a hot dog

8h = 13.20 . . . . . . . . . . . subtract 5.00

h = 1.65 . . . . . divide by 8

The price of a hot dog was $1.65.
