lyudmila [28]

Answer:

$x^2-3x$

Step-by-step explanation:

If we use polynomial division

$x^2-3x$

$x+3$ | $x^3+0x^{2} -9x$

$x^3+3x^2$

$-3x^2-9x$

$-3x^2-9x$

Kevin has a rectangular

Nikitich [7]

Answer:

20 feet long

Step-by-step explanation:

To solve this you need to use the Pythagorean theorum, $a^2+b^2=c^2$ , where c is the length of rope needed and A and B are the side lengths. Think of it like a right triangle.

So, the equation is

$12^2+16^2=c^2$

Which is then

$144+256=c^2$

$c^2=400$

And the possible values of c are 20 and -20.

From here we know the answer cannot be -20 because you cannot have a negatively long length of rope, so the answer must be 20 feet.

An average light bulb manufactured by the Acme Corporation lasts 300 days with a standard deviation of 50 days. Assuming that bu

notsponge [240]

Answer:

1. 90% 2. 10% 3. 50%

Step-by-step explanation:

Standard Deviation (σ) = 50 days

Average/Mean (μ) = 300days

Probability that it would last more than 300 days = P(Bulb>300 days)

We will assume there are 365 days in a year.

P(Bulb>300 days) implies that the bulb would

Using the normal equation;

z = standard/normal score = (x-μ)/σ where x is the value to be standardized

P(Bulb>300 days) implies x = 365 days

Therefore z = (365-300)/50 = 1.3

Using the normal graph for z=1.3, probability = 90%

2. P(Bulb<300 days) = 1 - P(Bulb>300 days)\

P(Bulb<300 days) = 1 - 0.9

P(Bulb<300 days) = 10%

3. P(Bulb=300 days) implies z=0 since x=300

Using the normal graph for z=0, probability =50%
