Lisa can make a costume twice as fast as Justin can. If they both work together, they can make it in 8 hours. How long will it t

Rashid [163]

Hi,

Concept: This is work & time related problem which can be solved in their inverse proportions.

Let Lisa can do a work in x hours.

Lisa's one hour work = 1 / x

According to the problem, Justin can do the same work in 2x hours.

Justin's one hour work = 1 / (2x)

Now, we shall find both 1 hour work just by adding their 1 hour's work.

Both 1 hour's work = (1 /x) + [1 / (2x)] = 3 / (2x)

Full works time = (2x /3) hours.

Again, according to the problem,

2x / 3 = 8

or, x= 12 hours.

Hence Justin will take 2x = 24 hours to complete work as alone.

Big chickens: The weights of broilers (commercially raised chickens) are approximately normally distributed with mean 1511 grams

ivolga24 [154]

Answer:

5.55% of broilers weigh between 1143 and 1242 grams

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

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

The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 1511, \sigma = 198$

What proportion of broilers weigh between 1143 and 1242 grams?

This is the pvalue of Z when X = 1242 subtracted by the pvalue of Z when X = 1143.

X = 1242

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

$Z = \frac{1242 - 1511}{198}$

$Z = -1.36$

$Z = -1.36$ has a pvalue of 0.0869

X = 1143

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

$Z = \frac{1143 - 1511}{198}$

$Z = -1.36$

$Z = -1.86$ has a pvalue of 0.0314

0.0869 - 0.0314 = 0.0555

5.55% of broilers weigh between 1143 and 1242 grams
