Answer:

Loss percentage = 40% (Approx)

Step-by-step explanation:

Given:

Cost price of home = $182,000

Sales price = $110,000

Find:

Loss percentage

Computation:

Loss = Cost price - Sales price

Loss = $182,000 - $110,000

Loss = $72,000

Loss percentage = [Loss / Cost price]100

Loss percentage = [72,000 / 182,000]100

Loss percentage = 39.5604

Loss percentage = 40% (Approx)

A scientist claims that 6% of viruses are airborne. (a) If the scientist is accurate, what is the probability that the proportio
soldi70 [24.7K]

Answer:

Probability that the proportion of airborne viruses in a sample of 529 viruses would be greater than 8% is 0.9545.

Step-by-step explanation:

For the given population the distribution of air-borne viruses is given as 6%. Now for this the value of Z score is given as

Z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}}

Here

  • \hat{p} is the sample measure which is 8% or 0.08
  • p is the population measure which is 6% or 0.06
  • n is the number of samples which is 529

So the Z score is given as

Z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}}\\Z=\dfrac{0.08-0.06}{\sqrt{\dfrac{0.08(1-0.08)}{529}}}\\Z=\dfrac{0.02}{\sqrt{\dfrac{0.08(0.92)}{529}}}\\Z=\dfrac{0.02}{\sqrt{\dfrac{0.0736}{529}}}\\Z=\dfrac{0.02}{0.01179}\\Z=1.6955

For this the score, the value of probability is calculated from the table as below:

P(\hat{p}>0.08)=p(Z>1.6955)\\=1-p(Z

Here value of p(Z<-1.6955) is given as 0.0455

P(\hat{p}>0.08)=p(Z>1.6955)\\P(\hat{p}>0.08)=1-p(Z0.08)=1-0.0455\\P(\hat{p}>0.08)=0.9545

Sweaters cost $39 each. This is $15 more than the price of a cap. Over the season, 725 caps were sold. What was the total sales
Leokris [45]

The price of a cap is 15 less than the sweater:

39-15 = $24

Multiply the price of a cap by amount sold:

725 x 24 = $17,400

Please anyone solve this for me..No spam.​
Tamiku [17]

Answer:

  • 3096

Step-by-step explanation:

<u>Given:</u>

  • 3x-\frac{1}{4y}=24

<u>Rewrite it as:</u>

  • 3x=\frac{1}{4y}+24
  • x=\frac{1}{12y}+8

<u>Simplify the expression:</u>

  • 8x(6x - \frac{1}{y} ) + \frac{1}{12y^2} (4 - 3y + 36xy^2) =
  • 8(\frac{1}{12y}+8)(6(\frac{1}{12y}+8) - \frac{1}{y} ) + \frac{1}{3y^2}  - \frac{1}{4y}  + 3x =
  • 8(\frac{1}{12y}+8)(48- \frac{1}{2y} ) + \frac{1}{3y^2}  - \frac{1}{4y}  + 24 + \frac{1}{4y}  =
  • 8(\frac{4}{y}+8*48- \frac{1}{24y^2} -\frac{4}{y} ) + \frac{1}{3y^2}  + 24  =
  • 8(384-\frac{1}{24y^2}) + \frac{1}{3y^2}  + 24  =
  • 8*384-\frac{1}{3y^2} + \frac{1}{3y^2}  + 24  =
  • 3072+24=
