<u>Corrected Question</u>

In the year 2009, the cost of a flat screen television can be  modeled by the equation C = -10t^2 + 500 where t is the  number of years since 2009. Factor this cost polynomial.

Answer:

C=10(50-t^2)

Using express exponents, you write C=10(50-t^2)

Step-by-step explanation:

To factor the cost polynomial, C=-10t^2+500, we follow these steps.

Step 1: Determine the greatest common divisor of the terms in the polynomial

The terms in the polynomial are -10t^2$ and 500

The greatest common divisor of -10t^2$ and 500 is 10.

Step 2: Factor the polynomial by dividing each of the terms with the greatest common divisor obtained above.

C=10\left(\dfrac{-10t^2}{10} +\dfrac{500}{10}\right)\\C=10(-t^2+50)\\$We can rewrite this as \\C=10(50-t^2)

Please simplify<br> 1,056=6(x+19)
bulgar [2K]

Answer: x = 157

Step-by-step explanation:

1056=6\left(x+19\right)

Switch sides:

6\left(x+19\right)=1056

Divide both sides by 6:

\frac{6\left(x+19\right)}{6}=\frac{1056}{6}

Simplify:

x+19=176

x+19-19=176-19

x=157

Mrs. Gomes found that 40% of students at her high school take chemistry. She randomly surveys 12 students. What is the probabili
34kurt

Answer:

Option b

Step-by-step explanation:

Given that Mrs. Gomes found that 40% of students at her high school take chemistry

since each student is independent of the other, we can say

X no of students who take chemistry is binomial with p = constant proba = 0.40

n = no of trials = no of students surveyed =12

Required probability = prob atmost 4 students take chemistry

=P(X\leq 4)\\=P(x=0)+P(x=1)+P(x=2)+P(x=3)+P(x=4)\\=\Sigma _0^4 12Cr (0.4)^r (0.6)^{12-r}

Substituting we get the cumulative probability

as

0.4382

round off to 0.438

Option b is correct answer
