What is the probability that a randomly selected male will have a foot length between 8 and 12.5 inches? P(8 < r < 12.5)=

melisa1 [442]

Answer:

0.8185 or 81.85%

Step-by-step explanation:

The mean length (μ) of an adult foot is 11 and the standard deviation (σ) is 1.5.

The z score is a measure in statistic used to determine the amount of standard deviation by which the raw score (x) is above or below the mean. If the raw score is above the mean, the z score is positive and if the raw score is below the mean the z sore is negative. It is given by:

$z=\frac{x-\mu}{\sigma}$

To calculate the probability that a randomly selected male will have a foot length between 8 and 12.5 inches, we first calculate the z score for 8 inches and then for 12.5 inches.

For 8 inches:

$z=\frac{x-\mu}{\sigma}=\frac{8-11}{1.5}=-2$

For 12.5 inches:

$z=\frac{x-\mu}{\sigma}=\frac{12.5-11}{1.5}=1$

From the normal distribution table, The probability that a randomly selected male will have a foot length between 8 and 12.5 inches = P(8 < x < 12.5) = P(-2 < z < 1) = P(z < 1) - P(z < -2) = 0.8413 - 0.0228 = 0.8185 = 81.85%

A squared +b squared= c squared
a squared+7 squared =10 squared
a squared + 49= 100
Then subtract 49 from 100 which is 51. Then your square root that number which is 7.14143

At the grocery store, you buy five cartons of eggs at $1.49 a carton and two gallons of orange juice at $3.06 a gallon. You give

Sloan [31]

Answer:

$6.43

Step-by-step explanation:

You start by multiplying $1.49 by 5 because you bought 5 cartons for $1.49, that would equal $7.45. Then, you multiply $3.06 by 2 because you bought 2 gallons, and you will get $6.12. Then you add both answers: $7.45 and $6.12. And you will get $13.57. Then, you hand him a $20, so $20 minus $13.57 equals $6.43! Please mark as brainliest! I worked hard! Plus hope this helps =)
