Answer:

The second integer is greater than the first.

Step-by-step explanation:

Since the first integer is the leftmost out of the two, this means that the second one must be greater than the first since it is to the right of it.

Answer:

Event is not unusual(p>0.05).

Step-by-step explanation:

Given that :

$p=0.10\\\\n=1100\\\\x=121$

#The sample proportion is calculated as:

$\hat p=\frac{x}{n}\\\\=\frac{121}{1100}\\\\=0.1100$

#Mathematically, the z-value is the value decreased by the mean then divided the standard deviation :

$z=\frac{\hat p- p}{\sqrt{\frac{p(1-p)}{n}}}\\\\\\\\=\frac{0.11-0.10}{\sqrt{\frac{0.10(1-0.10)}{1100}}}\\\\\\=1.1055$

#We use the normal probability table to determine the corresponding probability;

$P(X\geq 121)=P(Z>1.1055)\\\\=0.1314$

Hence, the probaility is more than 0.05, thus the event not unusual and thus this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased.

Considere os logaritmos log3=0,477 , log4=0,602 e / log5=0.699 logaritmos determine o valor de log5 12.

anygoal [31]

Given that :

log3=0.477 , log4=0.602 and log5=0.699

Now , as you know that

$\log\text{MN}=\log M +\log N$

We have to find the value of

$\log_{5}12$

So, $\log_{5}12$ = $\frac{\log12}{ \log5}$

= $\frac{\log 4+\log 3}{\log 5}\\$

Now Putting the values of log3, log4 and log5 in the above expression

$\log_{5}12=\frac{0.477 +0.602}{0.699}$

=1.0079/0.699

=1.5436..

=1.544 (approx)

So, the value of $\log_{5}12$ is 1.544(approx).

Which expression is equivalent to 9 p minus 3 p + 2? 8p 14p 6 p + 2 9 p minus 1

tankabanditka [31]

Your answer is c.

Step-by-step explanation: Let’s say P is worth 1: 9 times 1 equals 9: 3 times 1 equals 3: 9 - 3 = 6/ 6 + 2 equals 8. Now this is C: 6 times 1 equals 6/ 6+ 2 = 8
