A particular battery claims to have a mean life of 400 hours with a standard deviation of 30 hours. Approximately what percent o
Svetach [21]

Using the normal distribution, it is found that 25.14% of the batteries will last more than 420 hours.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

Z = \frac{X - \mu}{\sigma}

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

In this problem, we have that the mean and the standard deviation are given, respectively, by:

\mu = 400, \sigma = 30.

The proportion of the batteries will last more than 420 hours is <u>one subtracted by the p-value of Z when X = 420</u>, hence:

Z = \frac{X - \mu}{\sigma}

Z = \frac{420 - 400}{30}

Z = 0.67

Z = 0.67 has a p-value of 0.7486.

1 - 0.7486 = 0.2514.

0.2514 = 25.14% of the batteries will last more than 420 hours.

Find the missing letter which is N.the length is 25 in and the perimeter is 86 in <br>​
Illusion [34]

Answer:

Step-by-step explanation:

length = 25 in

Perimeter = 86 in

2*(length + width) = 86

2*(25 + N) = 86

Divide both sides by 2

25 + N = 86/2

25 + N = 43

Subtract 25 from both sides

25 + N - 25 = 43 - 25

N = 18

there are 600 pupils in a school. the ratio of boys to girls in this school is 3:5.How many girls and how many boys are in the s
a_sh-v [17]
In order to obtain a ratio of boys to girls equal to 3:5, the number of boys has to be written as 3 x and the number of girls as 5 x where x is a common factor to the number of girls and the number of boys. The total number of boys and girls is 600. Hence 

<span>3x + 5x = 600 </span>

Solve for x 

<span>8x = 600 </span>

<span>x = 75 </span>

Number of boys 

<span>3x = 3 × 75 = 225 </span>

Number of girls 

<span>5x = 5 × 75 = 375</span>
