A puppy weighs 2.8 pounds at birth and gained about 0.5 pounds per week. A kitten weighs 1.4 pounds at birth and gains about 1.2
seraphim [82]

The weight of the kitten will be no less than the weight of the puppy in 1.4 + 1.2x ≥ 2.8 + 0.5x week.

<h3>What is Inequality?</h3>

Statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Given:

A puppy weighs 2.8 pounds at birth and gained about 0.5 pounds per week.

A kitten weighs 1.4 pounds at birth and gains about 1.2 pounds per week.

puppy: 2.8 + 0.5x

Kitten: 1.4 + 1.2x

As, kitten is no less than puppy.

Kitten ≥ puppy

1.4 + 1.2x ≥ 2.8 + 0.5x

hence, the weight of the kitten will be no less than the weight of the puppy in 1.4 + 1.2x ≥ 2.8 + 0.5x week.

The life of Sunshine CD players is normally distributed with a mean of 4.1 years and a standard deviation of 1.3 years. A CD pla
castortr0y [4]

Using the normal distribution, we have that:

a) The sketch of the situation is given at the end of this answer.

b) The probability is:

P(2.8 \leq X \leq 7) = 0.8284

In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

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

  • It measures how many standard deviations the measure is from the mean.  
  • After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem:

  • Mean of 4.1 years, thus \mu = 4.1.
  • Standard deviation of 1.3 years, thus \sigma = 1.3.

Item a:

The part between 2.8 and 7 years is shaded on the sketch given at the end of this answer.

Item b:

The probability is the <u>p-value of Z when X = 7 subtracted by the p-value of Z when X = 2.8</u>, thus:

X = 7:

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

Z = \frac{7 - 4.1}{1.3}

Z = 2.23

Z = 2.23 has a p-value of 0.9871.

X = 2.8:

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

Z = \frac{2.8 - 4.1}{1.3}

Z = -1

Z = -1 has a p-value of 0.1587.

0.9871 - 0.1587 = 0.8284, thus:

P(2.8 \leq X \leq 7) = 0.8284
