This requires us to find the number of permutations of 6 different bands taken 2 at a time:
$6P2=\frac{6!}{(6-2)!}=30\ different\ votes.$

Answer:

Step-by-step explanation:

Given that:

sin2xcos x + cos2xsin x = -1

Recall that;

SInAcosB + cosASinB = SIn (A+B)

SIn (2x +x) = -1

Sin (3x) = -1

$x = \bigg [\dfrac{Sin ^{-1} (-1)}{3} \bigg ]$

$x = \dfrac{\pi}{2} + \dfrac{2 \pi \ k}{3}$

$x = \dfrac{\pi}{2}, \dfrac{7 \pi}{6}, \dfrac{11 \pi}{6}$

Answer:

The test statistic is $t = 3.744$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 140$

The The level of significance is $\alpha = 0.05$

The sample size is n = 18

The null hypothesis is $H_o : \mu = 140$

The alternative hypothesis is $H_a : \mu > 140$

The sample mean is $\= x = 155$

The standard deviation is $\sigma = 17$

Generally the test statistics is mathematically represented as

$t = \frac{\= x - \mu }{ \frac{ \sigma}{ \sqrt{n} } }$

substituting values

$t = \frac{ 155 - 140 }{ \frac{ 17 }{ \sqrt{18} } }$

$t = 3.744$
