What does the statement V(2)=T mean

Mathematics
1 answer:
alexgriva [62]3 years ago
6 0

Answer:

Step-by-step explanation:

V(2) means that whenever you see v(x) then the x will have a value of 2

For example,

v(x) = x^2 + 56x

v(2) means 2^2 + 58*2

F(x)=(x^3+4x^2+7x-9) d(x)=(x+3)<br><br> divide using long division
Alchen [17]

The result is x^2 +x +4 -21/(x+3).

_____

Polynomial long division tends to be easier than numerical long division because the quotient term never needs adjustment. It is always the ratio of the highest degree terms of the dividend and divisor.

See the attachment for the intermediate steps.

Y and x have a proportional relationship, and y = 12 when x = 5. What is the value of y when x = 8?
serious [3.7K]
When x = 8 y = 15

The way to figure this out is to subtract 12 by 5. That’s 7 so there’s a difference of 7 between both of the numbers.

Hope this helped!

A random sample of 16 men have a mean height of 67.5 inches and a standard deviation of 2.22.2 inches. Construct a​ 99% confiden
saw5 [17]

Answer: \approx1.49

Step-by-step explanation:

We know that the confidence interval for population standard deviation is given by :-

\sqrt{\dfrac{(n-1)s^2}{\chi^2_{\alpha/2}}}

, where n= sample size

s = sample standard deviation.

\chi^2_{\alpha/2}  and \chi^2_{1-\alpha/2}= Chi-square critical value for degree of freedom (n-1) and significance level (\alpha).

Given : \alpha=1-0.99=0.01

n= 16

Critical ch-square values for degree of freedom 15 and \alpha=0.01will be :

\chi_{\alpha/2}=\chi_{0.005}=32.80132

\chi_{1-\alpha/2}=\chi_{0.995}=4.6009

Then , the required 99% confidence interval for the population standard​ deviation will be :

\sqrt{\dfrac{(15)(2.2)^2}{32.80132}}

\sqrt{2.21332556129}

1.48772496157

\approx1.49

Hence, the a​ 99% confidence interval for the population standard​ deviation :
