Which algebraic expression is a polynomial with a degree of 2?

1 answer:

5 0

I do not see an attachment, but it is really quite simple. All you need to do is find the polynomial where its highest exponent would be 2. For example:

x³+x²+6x-9 would be wrong because the highest exponent is three.

However, x²+8x-6 is correct because the highest exponent is 2. Very simple.

Answer: $(12.007\ , \ 12.033)$

Step-by-step explanation:

Given : Sample size : n= 36 , which is a large sample (n>30) so the test applied here is z-test.

Significance level : $\alpha: 1-0.95=0.05$

Using Standard normal table , Critical value : $z_{\alpha/2}=1.96$

Sample mean : $\overline{x}=12.02$

Standard deviation: $\sigma= 0.04$

The confidence interval for population means is given by :-

$\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

i.e. $12.02\pm(1.96)\dfrac{0.04}{\sqrt{36}}$

$\approx12.02\pm0.013=(12.02-0.013,\ 12.02+0.013)\\\\=(12.007\ , \ 12.033)$

Hence, the 95 percent confidence interval for the fill rate = $(12.007\ , \ 12.033)$

A bag of m&m's has 4 red, 7 green, 8 blue, and 6 yellow m&m's. what is the probability of randomly pickinga blue or gree

bogdanovich [222]

Step-by-step explanation:

a probability is always desired cases over total possible cases.

the bag has 4 + 7 + 8 + 6 = 25.

so, when we pick a random M&M we have total 25 possible outcomes.

the desired cases are to pick a green or a blue M&M.

that means these are 7+8 = 15 cases.

the probability to pick one or of the desired cases is

15/25 = 3/5 = 0.6

The function f (x) = 57.8 (1.02) x gives the approximate number of passenger cars, in millions, in the United States x years aft

Leviafan [203]

Assume this is f(x)=57.8(1.02)ˣ. This is a 2% increase each year.

When f(x)=200, 57.8(1.02)ˣ=200, (1.02)ˣ=200/57.8
Taking logs, xlog(1.02)=log(200/57.8), x= log(200/57.8)/log(1.02)=62.685.
Add 1960 to 62.685=2023 approx.
