A company produces and sells homemade candles and accessories. Their customers commonly order a large candle and a matching candle stand. The weights of these candles have a mean of 500g and a standard deviation of 15g. The weights of the candle stands have a mean of 200g and a standard deviation of 8g. Both distributions are approximately normal.
Let T= the total weight of a randomly selected candle and a randomly selected stand, and assume that the two weights are independent.
If the total weight T of the two items is under 683g, the company gets a discount on shipping.
Find the probability that the total weight is under 683g.
You may round your answer to two decimal places.
P(T<683)≈

Answers

Answer:

P(T<683) = 0.1587 = 15.87% ≈ 16%.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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 p-value, we get the probability that the value of the measure is greater than X.

Sum of normal variables:

When two normal variables are added, the mean is the sum of the means, while the standard deviation is the square root of the sum of the variances.

The weights of these candles have a mean of 500g and a standard deviation of 15g. The weights of the candle stands have a mean of 200g and a standard deviation of 8g.

The package consists of one candle of each type. So

[tex]\mu = 500 + 200 = 700[/tex]

[tex]\sigma = \sqrt{15^2 + 8^2} = 17[/tex]

Find the probability that the total weight is under 683g.

This is the pvalue of Z when X = 683.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{683 - 700}{17}[/tex]

[tex]Z = -1[/tex]

[tex]Z = -1[/tex] has a pvalue of 0.1587

So

P(T<683) = 0.1587 = 15.87% ≈ 16%.

Use Green's Theorem to evaluate the line integral along the given positively oriented curve.

∫ c(y+e√x)dx+(2x+cosy2)dy,

C is the boundary of the region enclosed by the parabolas

y=x^2 and x=y^2

Answers

Answer:

∫ C ( y + e√x) dx  +  ( 2x + cosy² ) dy = 1/3

Step-by-step explanation: See Annex

Green Theorem establishes:

∫C ( Mdx  +  Ndy )  = ∫∫R ( δN/dx  -  δM/dy ) dA

Then

∫ C ( y + e√x) dx  +  ( 2x + cosy² ) dy

Here

M = 2x  + cosy²           δM/dy  =  1

N = y + e√x                 δN/dx  =  2

δN/dx  -  δM/dy  =  2  -  1   = 1

∫∫(R) dxdy   ∫∫ dxdy

Now integration limits  ( see Annex)

dy  is from   x  = y²    then     y = √x    to  y = x²   and for dx

dx   is from 0   to  1 then

∫ dy    = y | √x   ;   x²      ∫dy    =  x² - √x

And

∫₀¹ ( x² - √x ) dx    =  x³/3  - 2/3 √x |₀¹    =   1/3 - 0

∫ C ( y + e√x) dx  +  ( 2x + cosy² ) dy = 1/3

Sunscreen is a hot topic every summer. Dermatologists recommend wearing it every day to protect your skin from solar radiation. But skeptics say it can cause more harm than good by exposing you to dangerous chemicals and causing Vitamin D deficiency. There are two good reasons to wear sunscreen: to protect your health, and to protect your looks. Excessive exposure to sunlight can cause skin cancer. Over time, it also makes skin saggy and wrinkled. Numerous studies have shown that regular use of sunscreen reduces the occurrence of skin cancer, and also keeps skin smoother and more elastic. In contrast, there is little evidence that sunscreens currently on the market contain ingredients that are harmful when absorbed. It doesnt take much sunlight to produce all the Vitamin D needed for good health, either. Which of the options below is the most effective conclusion to the essay? Dermatologists recommend wearing sunscreen every day to protect your skin from the suns radiation, although some skeptics worry about exposure to dangerous chemicals and Vitamin D deficiency. Many studies have shown that regular use of sunscreen is good for you. There is little evidence it is harmful. In closing, the evidence for wearing sunscreen is clear and bright, while the arguments against it are partly cloudy at best. Use it every day, and your skin will look and be healthy. Walt Whitman said, Keep your face always toward the sunshine and shadows will fall behind you. Easy to for him say when he always wore a thick beard and big hat, but everyone else should either seek out those shadows or put on some sunscreen. Poetry can soothe your soul, but only sunscreen will protect your skin. Sunscreens work in two ways. Some use minerals to form a physical barrier that reflects radiation away from your skin. Others include chemical compounds that absorb the sunlight before your skin does. When used properly, both types of sunscreen can protect your skin from damage.
