The domain of any polynomial is "the set of all real numbers."

I think you may have mistyped your function, meaning F(x)=4-3x-x^2. But either way, F(x-2)=4-3x-x^2 and F(x) are polynomials, and so their domains are "the set of all real numbers."

For what value of a is (a,9) a solution for the equation y=2x+1?

Ivahew [28]

Answer:

Step-by-step explanation:

(a,9).......we dont know " a " (or x) but we do know y...it is 9

so sub in 9 for y and solve for x

y = 2x + 1

9 = 2x + 1

9 - 1 = 2x

8 = 2x

8/2 = x

When obtaining a confidence interval for a population mean in the case of a finite population of size N and a sample size n whic

Elanso [62]

Answer:

95% Confidence interval for the mean

$142.8 \leq\mu\leq158.4$

Step-by-step explanation:

We have to calculate a 95% confidence interval for the mean of a finite population.

The error is multiplied by the following finite population correction factor:

$cf=\sqrt{\frac{N-n}{N-1} }$

The standard deviation can be estimated as

$\sigma=\frac{s}{\sqrt{n}} \sqrt{\frac{N-n}{N-1} } =\frac{24.4}{\sqrt{32} }* \sqrt{\frac{200-32}{200-1} }=3.963$

The 95% confidence interval has a z value of 1.96, so it becomes:

$M-z*\sigma_c\leq\mu\leq M+z*\sigma_c\\\\150.6-1.96*3.963\leq\mu\leq 150.6+1.96*3.963\\\\ 142.8 \leq\mu\leq 158.4$

Please give me the right answer?

baherus [9]

(5 3/10) (m) + (5 3/10) (m) + (5 3/10) (m) + (5 3/10) (m)

P = 53/10 + 5 3/10 + 5 3/10 + 5 3/10

P = 53/10 + 53/10 + 5 3/10 + 5 3/10

P = 53/5 + 5 3/10 + 5 3/10

P = 53/5 + 53/10 + 5 3/10

P = 159/10 + 5 3/10

P = 159/10 + 53/10

P = 106/5

P = 21 1/5 meters

Answer: 21 1/5 meters (Decimal: 21.2m)

Hope that helps!!!! Have a great day!!!! : )
