A smart phone regularly sells for $180.00 but is on sale for 30% off. What is the amount of the discount?

Answers

Answer 1

Answer:

$54

Step-by-step explanation:

The amount of the discount can be found by multiplying 180 by 0.3 which is 54.

If you also need to know the new total it would be $126 because

180 - 54 = 126

. For a normal distribution, find the percentage of data that are a. Within 1 standard deviation of the mean.________ b. To the right of 1.5 standard deviations below the mean________ c. More than 0.5 standard deviations away from the mean

Answers

Answer:

a. The percentage of data within 1 standard deviation of the mean is 68.26%.

b. The percentage of data to the right of 1.5 standard deviations below the mean is of 93.32%.

c. The percentage of data more than 0.5 standard deviations away from the mean is of 61.7%.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

a. Within 1 standard deviation of the mean

Between [tex]Z = -1[/tex] and [tex]Z = 1[/tex]

This is the pvalue of Z = 1 subtracted by the pvalue of Z = -1.

Z = 1 has a pvalue of 0.8413

Z = -1 has a pvalue of 0.1587

0.8413 - 0.1587 = 0.6826

The percentage of data within 1 standard deviation of the mean is 68.26%.

b. To the right of 1.5 standard deviations below the mean

Greater than [tex]Z = -1.5[/tex], that is, 1 subtracted by the pvalue of Z = -1.5.

Z = -1.5 has a pvalue of 0.0668

1 - 0.0668 = 0.9332

The percentage of data to the right of 1.5 standard deviations below the mean is of 93.32%.

c. More than 0.5 standard deviations away from the mean

Below [tex]Z = -0.5[/tex] or above [tex]Z = 0.5[/tex]. These percentages are the same, so we find one and multiply by 1.

Below Z = -0.5

This is the pvalue of Z = -0.5, which is 0.3085

0.3085*2 = 0.617

The percentage of data more than 0.5 standard deviations away from the mean is of 61.7%.

What fraction of 400 gallons is 180 L? Give your answer in simplest form. 1 gallon = 4.5 L.​

Answers

Answer:

400 gallons are 1100 / 63 of 126 L.

Step-by-step explanation:

Given

1 Gallon = 4.5 L

To determine

What fraction of 400 gallons is 180 L

as

1 Gallon = 4.5 L

so

400 Gallons = 400 × 4.5

                     = 1800 L

In order to determine the fraction of 400 gallons is 180 L, just divide 1800 by 180, so

Fraction = 2200 ÷ 126

              = 1100 ÷ 63

Therefore, 400 gallons are 1100 / 63 of 126 L.

The selling price of an item is $600. It is marked down by 10%, but this sale price is still marked up
from the cost of $450. Find the markup from cost to sale price.
The markup is $ (Round to the nearest dollar as needed.)

Answers

Step-by-step explanation:

Sale price

= Marked down by 10% from selling price

= 90% of selling price

= 0.9 * $600

= $540.

Sale price - Cost price

= $540 - $450 = $90.

The markup from cost to sale is $90.

The markup from cost to sale price will be $90.

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

The selling cost of a thing is $600. It is discounted by 10%, however, this deal cost is as yet increased from the expense of $450.

The sale price is given as,

Sale price = 0.90 x $600

Sale price = $540

The markup cost to sale will be given as,

⇒ $540 - $450

⇒ $90

The markup from cost to sale price will be $90.

What is the equation of the line in slope-intercept form?

Answers

Answer:

The equation of the line in slope-intercept form is:

[tex]y = x + 4[/tex]

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where  m is the slope  and b is the y-intercept

Given the equation

(1, 5) (2, 6)

Determining the slope between (1, 5) and (2, 6)

(x₁, y₁) = (1, 5)

(x₂, y₂) = (2, 6)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                 =  [5 - 4] / [1 - 0]

                  = 1 / 1  

                   = 1

Thus, the slope of the line = m = 1

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 4

Thus, the y-intercept b = 4

now substituting b = 4 and m = 1 in the slope-intercept form

[tex]y = mx + b[/tex]

[tex]y = (1)x + 4[/tex]

[tex]y = x + 4[/tex]

Therefore, the equation of the line in slope-intercept form is:

[tex]y = x + 4[/tex]

The weights of the fish in a certain lake are normally distributed with a mean of 19 lbs and a standard deviation of 6. If 25 fish are randomly selected, what is the probability that the mean weight will be greater than 17.2 lbs

Answers

Answer:

0.93319

Step-by-step explanation:

We solve the question using the z score formula

z = (x-μ)/σ/√n where

x is the raw score = 17.2 lbs

μ is the population mean = 19 lbs

σ is the population standard deviation = 6

n is the random number of samples = 25 fishes

Greater than sign = >

For x > 17.2 lbs

z = 17.2 - 19/6/√25

z = 17.2 - 19/ 6/5

z = 17.2 - 19/1.2

z = -1.5

Probability value from Z-Table:

P(x<17.2) = 0.066807

P(x>17.2) = 1 - P(x<17.2)

P(x>17.2) = 1 - 0.066807

P(x>17.2) = 0.93319

Therefore, that the probability that the mean weight will be greater than 17.2 lbs is 0.93319

The stock market dropped 220 points on Monday. It lost another 48 points on Tuesday, and on Wednesday, it gained 96 points. What was the amount of change over those three days.

Answers

Answer: 48 points gained in those 3 days.

Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.

Subtract 220-48.It‘ll be 172.

Add 172 with 96. 172+96=268.

Subtract 268 with how much points the stock market had 3 days ago. 268-220. So it would be about 48 points gained.

Answers

Answer:

Value after one year = Rs 9000

Step-by-step explanation:

The depreciation refers to a reduction in value of the asset (sofa-set) due to usage and other factors. The depreciation charge at the rate of 10% means that the reduction in value at 10% of cost per year.

Depreciation per year = 10000 * 0.1 = Rs 1000

Value after one year = 10000 - 1000

Value after one year = Rs 9000
