Answer:

Step-by-step explanation:

To the tenth term in the sequence we need to change all the n's to 10.

so...

a₁₀ = 4 + ( -1 )¹⁰ =

4 + (-1) = (Because -1¹⁰ = -1)

4 - 1 = 3

A simple random sample with n = 58 provided a sample mean of 24.5 and a sample standard deviation of 4.4. (Round your answers to

nasty-shy [4]

Answer: (23.53, 25.47)

Step-by-step explanation:

The confidence interval for population mean(when population standard deviation is unknown) is given by :-

$\overline{x} \pm\ t^*\dfrac{s}{\sqrt{n}}$

, where $\overline{x}$ = sample mean

n = sample size.

s = sample standard deviation.

t* = Critical value.

Given : $\overline{x}=24.5$

s= 4.4

Confidence level = 90% =0.090

Significance level = $\alpha=1-0.90=0.10$

Sample size : n= 58

Degree of freedom : df= n-1= 57

Using t-distribution table , the critical value :

$t_{\alpha/2,\ df}= t_{0.05,\ 57}=1.6720$

Then, the confidence interval will be :-

$24.5 \pm\ (1.6720)\dfrac{4.4}{\sqrt{58}}$

$24.5 \pm\ (1.6720)\dfrac{4.4}{7.61577310586}$

$24.5 \pm\ 0.965995165263\approx24.5\pm0.97\\\\=(24.5-0.97,\ 24.5+0.97)\\\\=(23.53,\ 25.47)$

Hence, a 90% confidence interval for the population mean = (23.53, 25.47)

Uh at this point I have no more creative questions so: 2x+4(2x+7)=3(2x+4)

asambeis [7]

Answer:

x = -3/2

Step-by-step explanation:

=> 2x+4(2x+7) = 3(2x+4)

=> 2x+8x+18 = 6x+12

=> 10x + 18 = 6x+12

=> 10x-6x = 12-18

=> 4x = -6

=> x = -3/2
