Answer:

8. 9^2, this can be simplified to 9*9 which is 81!

9. -5^4 can be simplified to -5*-5*-5*-5 which is 625.

10. (-3)^4 can be simplified to -3*-3*-3*-3 which is 81!

And finally 11. (1/4)^3 can be simplified to (1/4)(1/4)(1/4) which is 1/64.

What is the fifth term in the binomial expansion of (x + 5)^8?O 175,000x³O 43,750x4O 3,125x5O 7,000x

enyata [817]

Solution:

Given the expression below

$(x+5)^8$

Applying the binomial theorem formula

$\begin{gathered} \left(a+b\right)^n=\sum_{k=0}^n{\binom{n}{k}}a^{n-k}b^k \\ Where \\ a=x \\ b=5 \\ n=8 \\ k=4\text{ i.e. fifth term} \end{gathered}$

For the fifth term, i.e

$\sum_{k=4}^8{\binom{8}{4}}x^{8-4}5^4=\frac{8!}{4!(8-4)!}\cdot x^4\cdot(625)=(70)(625)(x^4)=43750x^4$

Hence, the fifth terms is

$43750x^4$

N = 36 = 24.6 s = 12 h0: ? 20 ha: ? > 20 refer to exhibit 9-1. the test statistic is

solong [7]

To find the test statistic or z-score given sample number (n), sample mean (x), standard deviation (σ), and population mean (μ), we can use

$z-score = \frac{x - \mu }{\sigma / \sqrt{n}}$

Given that n = 36, x = 24.6, μ = 20, and σ = 12,

$z-score = \frac{24.6 - 20}{12 / \sqrt{36}}$
$z-score = \frac{4.6}{2} = 2.3$

From this, we see that the test statistic is 2.3.

Answer: 2.3

Answer:

$1+\sqrt{2}\\$ , $1.5-\sqrt{2}$ , $\sqrt{2} -1$ , $\sqrt{2}-1 , 0.15+\pi /1000 , \sqrt{2} +0.001$ $2.357+\pi /1000000$ $0.0001+\pi /10000000$ and I think you got it, just add to the smaller one $\pi /10000000000000\\$
