Choose the polynomial written in standard form.

posledela

<span>Standard form means that you write the terms by descending degree.

</span> $x^4y^2+4x^3y+10x^2$
<span>
The degree of the first term </span> $x^4y^2$ is $4+2=6$ .
The degree of the second term $4x^3y$ is $3+1=4$ .
The degree of the third term $10x^2$ is $2$ .

The terms are written by descending degree. Therefore, polynomial $x^4y^2+4x^3y+10x^2$ is written in standard form.

Kyah and Jasmine are running in a long distance race. They are running around a track that is 1/5 of km long. Kyah can run 6 lap

Oliga [24]

Jasmine is running faster.

Since the track is 1/5 of a km and she can run 1km in 7 minutes, divide seven to get 1.4.

This means that Jasmine can run one lap in 1.4 minutes.

Since a Kyah can run 6 laps in 10 minutes, do 10 divided by 6 and the answe will be 1.6 repeating.

1.4 < 1.6 so Jasmine is faster

The lifetime of a certain type of battery is normally distributed with mean value 11 hours and standard deviation 1 hour. There

victus00 [196]

Answer: The required lifetime value is 11.27.

Step-by-step explanation:

Since we have given that

Mean value = 11 hours

Standard deviation = 1 hour

The total lifetime of all batteries in a package exceeds that value for only 5% of all packages.

So, α = 0.95, z= 1.645

n = 9

So, the lifetime value would be

$x=\mu+z\times \dfrac{\sigma}{\sqrt{n}}\\\\x=11+1.645\times \dfrac{1}{\sqrt{36}}\\\\x=11+1.645\times \dfrac{1}{6}\\\\x=11.27$

Hence, the required lifetime value is 11.27.
