package. Because the package is so expensive, the company wants to advertise an impressive guarantee

for the life expectancy of its computer control system.

The guarantee policy will refund the full purchase price if the computer fails during the guarantee period.

The research department has done tests that show that the mean life for the computer is 35 months, with standard deviation of 5 months. The computer

life is normally distributed. How long can the guarantee period be if management does not want to refund the purchase price on more than 6.596 of the

Magic Video packages?

The solution of f(x)=x^3-2x^2- 9x + 18 is

Tom [10]

Answer:

x = -3, 2, 3.

Step-by-step explanation:

f(x )= x^3 - 2x^2 - 9x + 18 We factor this by grouping:

f(x) = x^2(x - 2) - 9(x - 2)

f(x) = (x ^2- 9)(x - 2)

f(x) = (x - 3)(x + 3)(x - 2).

The zeroes of the function are:

x = -3, 2, 3.

A flower bed in your yard is in the shape of a right triangle. The perpendicular sides of the bed measure 14 feet and 11 feet. C

aev [14]

The area of the flower bed is 77 square feet

<h3>How to determine the area?</h3>

The given parameters are:

Shape = Triangle
Perpendicular sides = 14 feet and 11 feet

The area of the flower bed is calculated as:

Area = 0.5 * Product of perpendicular sides

So, we have:

Area = 0.5 * 14 * 11

Evaluate

Area = 77

Hence, the area of the flower bed is 77 square feet

Maya had $27. She spent all the money on buying 3 burgers for $x each and 2 sandwiches for $y each. If Maya would have bought 2

defon

Answer:

Option C

The student's conclusion is correct because the solution to the system of equations $3x+2y=27$ and $2x+y=16$ is $(5,6)$

Step-by-step explanation:

Let

x------> the cost of each burger

y-----> the cost of each sandwich

we know that

$3x+2y=27$ -----> equation A

$2x+y=(27-11)$

$2x+y=16$ ----> equation B

Solve the system of equations

Multiply the equation B by $-2$

$-2(2x+y)=-2*16$ -----> $-4x-2y=-32$ ------> equation C

Adds equation A and equation C

$3x+2y=27 \\-4x-2y=-32\\ ----------\\ 3x-4x=27-32\\ -x=-5\\x=5$

Substitute the value of x in the equation B

$2(5)+y=16$

$10+y=16$

$y=6$

The solution of the system of equations is the point $(5,6)$

The price of each burger is $\$5$

The price of each sandwich is $\$6$
