What polynomails has the roots of -6, -4 ,and 1? A)x³-9x²-22x+24 B) x³-x²-26x-24 C) x³+x²-26x+24 D)x³+9x²+14x-24.

never [62]

Answer:

x = 1 or x = -4 or x = -6 thus d: is your answer

Step-by-step explanation:

Solve for x over the real numbers:

x^3 + 9 x^2 + 14 x - 24 = 0

The left hand side factors into a product with three terms:

(x - 1) (x + 4) (x + 6) = 0

Split into three equations:

x - 1 = 0 or x + 4 = 0 or x + 6 = 0

Add 1 to both sides:

x = 1 or x + 4 = 0 or x + 6 = 0

Subtract 4 from both sides:

x = 1 or x = -4 or x + 6 = 0

Subtract 6 from both sides:

Answer: x = 1 or x = -4 or x = -6

How many square feet are in 100 m squared

Vikentia [17]

Answer:

100 Sq Mt = 1135.69 Sq Ft

Step-by-step explanation:

We are required to find how many square feet are in 100 m squared.

1 meter = 3.37 ft

1 metre x 1 meter = 3.37 x 3.37 Sq ft

1 Sq Mt = 11.3569 Sq ft

100 sq Mt = 100 x 11.3569 sq ft

100 sq mt = 1135.69 Sq ft

Hence

100 Sq Mt = 1135.69 Sq Ft

An insurance company has 10,000 automobile policyholders. The expected yearly claim per policyholder is $240, with a standard de

elena55 [62]

Answer:

almost 0%

Step-by-step explanation:

Given that for an insurance company with 10000 automobile policy holders, the expected yearly claim per policyholder is $240 with a standard deaviation of 800

using normal approximation, the probability that the total yearly claim exceeds $2.7 million is calculated as follows:

Sea sumatoria de x = SUMX, tenemos que:

$P (SUMX \geq 2700000) = P(\frac{SUMX - 240*10000}{800 *\sqrt{10000} } \geq \frac{2700000 - 240*10000}{800 *\sqrt{10000} })$

$= P (z\geq \frac{2700000 - 240*10000}{800 *\sqrt{10000}})$

= P (z => 3.75)

= 1 - P ( z < 3.75)

P = 1 - 0.999912

P = 0.000088

Which means that the probability is almost 0%
