Which table represents a linear function?

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.

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%.

The Volume of Rectangular Prism

Given a rectangular prism of dimensions W, L, and H, its volume is the product of the three dimensions:

V = WLH

The figure shows the dimensions:

L=3 cm

[tex]W=\frac{4}{3}\ cm[/tex]

[tex]H=\frac{3}{5}\ cm[/tex]

Thus, the volume is:

[tex]V =3*\frac{4}{3}*\frac{3}{5}\ cm^3[/tex]

[tex]V =\frac{36}{15}\ cm^3[/tex]

Simplifying:

[tex]\boxed{V =\frac{12}{5}\ cm^3}[/tex]

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

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]

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.

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

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

So, the value after one year will be,

Value after one year = 10000 - 1000

Value after one year = Rs 9000

[tex]H_0 : p_1 = p_2\\\\H_a : p_1 \neq p_2\\[/tex]

Testing the statistics values:

[tex]p_1 = \frac{141}{523} = 0.2696 \\\\ n_1 = 523\\\\p_2 = \frac{81}{477} = 0.1698\\\\ n_2 = 477[/tex]

[tex]p = \frac{(p_1 \times n_1 + p_2 \times n_2)}{(n_1 + n_2)}[/tex]

  [tex]= \frac{(0.2696 \times 523 + 0.1698 \times 477)}{( 523 + 477)}\\\\= \frac{(141.0008 + 80.9946)}{(1000)}\\\\= \frac{(221.99)}{(1000)}\\\\= \frac{(222.0)}{(1000)}\\\\= 0.2220[/tex]

[tex]SE = \sqrt{ p \times ( 1 - p ) \times [ (\frac{1}{n_1}) + (\frac{1}{n_2}) ] }[/tex]

     [tex]= \sqrt{( 0.222 \times (1-0.222) \times((\frac{1}{523}) + (\frac{1}{477})))}\\\\= 0.0263[/tex]

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.

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.
