Yes, this is a polynomial, but a special form of a polynomial with just one term which is called a monomial .

Someone help me out please

Hey there!

150 = 8x + 6y

↠ 150 = 8x + 6(9)

↠ 8x + 6(9) = 150

↠ 8x + 54 = 150

SUBTRACT 54 to BOTH SIDES

8x + 54 - 54 = 150 - 54

CANCEL out: 54 - 54 because that gives you 0

KEEP: 150 - 54 because helps solve for x

↣150 - 54 = 96↢

NEW EQUATION: 8x = 96

DIVIDE 8 to BOTH SIDES

8x/8 = 96/8

CANCEL out: 8/8 because that gives you 1

KEEP: 96/8 because that gives the value of x

96/8 = x

x = 12

Answer: x = 12

Good luck on your assignment and enjoy your day!

From previous polls, it is believed that 66% of likely voters prefer the incumbent. A new poll of 500 likely voters will be cond

Vladimir79 [104]

Answer:

The mean and standard deviation of the number preferring the incumbent is mean = 330, standard deviation = 10.59.

Step-by-step explanation:

We are given that From previous polls, it is believed that 66% of likely voters prefer the incumbent.

A new poll of 500 likely voters will be conducted. In the new poll the proportion favoring the incumbent has not changed.

Let p = probability of voters preferring the incumbent = 66%

n = number of voters polled = 500

<u>So, the mean of the number preferring the incumbent is given by;</u>

Mean = $n \times p$ = $500 \times 0.66$

= 330 voters

<u>And, standard deviation of the number preferring the incumbent is given by;</u>

Variance = $n \times p\times (1-p)$

= $500 \times 0.66 \times (1-0.66)$

= 112.2

So, Standard deviation = $\sqrt{Variance}$

= $\sqrt{112.2}$ = 10.59

2. Find the compound interest on Rs.25, 000 after 2 years compounded

Allushta [10]

Answer:25,000 in 2 years at annual compound interest, if the rates for the successive years be 4% and 5% per annum respectively is: (1) Rs. 30,000 (2) Rs. 26,800 fa) Rs.

A=P[1+

100

]

⇒ A=Rs.25,000×(

100

106

)

⇒ 25,000×

⇒ A=Rs.29,775.40

⇒ CI=A−P

⇒ Rs.29,775.40−Rs.25,000

∴ CompoundInterest=Rs.4775.40.
