Answer:

11 , 17 , 24

Step-by-step explanation:

• Since the Lowest number is 11 and the range is 13 then

The greatest number is 11 + 13 = 24

• Therefore the three numbers are  11 , 17 and 24

because the median of the set 11 , 17 , 24 is 17

a. [tex]x^4 + 4x^2 + 4[/tex]

b. x = ∛-1 and -3

a.  Given

(x² + 2)²

First, we open up the bracket

Multiply through

[tex]x^4 + 2x^2 + 2x^2 + 4[/tex]

Collect like terms

[tex]x^4 + 4x^2 + 4[/tex]

b. Let's factorize

[tex]x^4 + 4x + 3[/tex]

Find the factors of 3 that are products of 4, they are 3 and 1

Use it to replace 4x as 3x and x

[tex]x^4 + 3x + x + 3[/tex]

Let's make the expression two

[tex](x^4 + 3x) (x+ 3)[/tex]

Find the common factor

Answer:

Days of Asset Turnover The Enterprise Accounting System specifies that the net revenue from main business of an enterprise should be the amount of revenue from main business after deducting sales discounts and sales discounts, which is called net revenue from main business. Total asset turnover ratio = total sales revenue / average total assets x 100%.

Step-by-step explanation:

The width of the model is 3.6 inches.

The figures with the same shape are said similar when the sides of both the figures are in proportion.

Sara has a model of length = 18inches.

The original ship has a length is 160 ft

The width of the original ship is 32 ft

The model is a scaled-down version of the original figure and so the length and width of the model will be in the same proportion as the original dimensions.

Let x represents the width of the model then,

160/18 = 32/x

x = 32 * 18 / 160

x= 3.6 inches.

Therefore, the width of the model is 3.6 inches.

The amount of interest you would be paying in Year 2 is: $2,492.62.

First step is to calculate the Equal Monthly Payment

Equal Monthly Payment=P×r×(1+r)^t/(1+r)^t-1

Where:

P=Principal=$36,500

r=Rate=7.7%

t=Time=7 years

Equal Monthly Payment=36,500×0.077×(1+0.077)^7÷(1+0.077)^7-1

Equal Monthly Payment=36,500×0.077×(1.077)^7÷(1.077)^7-1

Equal Monthly Payment=36,500×0.077×1.6807763÷1.6807763-1

Equal Monthly Payment=4,723.82/0.6807763

Equal Monthly Payment=$6,938.875

Second step is to calculate Year 1 Closing balance

Year 1 Closing balance  = Beginning  balance + Interest - EMI Payment

Year 1 Closing balance=  $36,500 +($36,500×7.7%) - $6,938.875

Year 1 Closing balance=  $36,500 + $2,810.5 -$6,938.875

Year 1 Closing balance =   $32,371.625

Third step is to calculate year 2 interest

Year 2 Interest= $32,371.625×7.7%

Year 2 Interest=$2,492.62

Therefore the amount of interest you would be paying in Year 2 is: $2,492.62.

Answer:

Last graph that slopes upwards from left to right and that has an y-intercept of -1

Step-by-step explanation:

let us pick some points!(you can chose any two)

when x =3 , y = 14 : helps us get points (3,14)

when x =1 , y = 4 : helps us get points (1,4)

so we find the gradient using the two points:

[tex]gradient \ =\frac{14-4}{3-1} =\frac{10}{2} \\[/tex]

we now use gradient 10/2 and point (1,4) to find the equation  of the line:

[tex]\frac{10}{2} =\frac{y-4}{x-1} \\2(y-4)=10(x-1)\\2y-8=10x-10\\2y=10x-10+8\\2y=10x-2\\y=5x-1[/tex]

from the equation of the line found we are able to find the y- intercept of the line is -1 and that the line has a positive gradient thus should slope upwards from left to right.

From the pictures you posted, we pick the last graph as it seem to slope upwards from left to right and has the line cutting y axis at around -1

Answer:

C 12/48

Step-by-step explanation:

Original fraction:

x/y

The ratio of the numerator to the denominator is 1:4, so

x/y = 1/4

Cross multiply:

y = 4x

If three is added to the numerator and subtracted from the denominator, the new fraction reduces to one-third.

(x + 3)/(y - 3) = 1/3

Cross multiply:

3(x + 3) = 1(y - 3)

3x + 9 = y - 3

Above, we have y = 4x, so substitute 4x for y in the equation just above and solve for x.

3x + 9 = 4x - 3

12 = x

x = 12

y = 4(12) = 48

The original fraction is x/y = 12/48

When there are two possibilities then we calculate the null hypothesis if the hypothesis is true hypothesis is accepted if it is

To conduct a hypothesis test for the above situation. We define the null hypothesis and the alternative hypothesis.

The null hypothesis is the claim that the average commute time to downtown is 20 minutes while the alternative hypothesis is a contradiction of the null hypothesis which is that the average commute time to downtown is not 20 minutes.

i.e. H0: μ = 20 and H1:  μ ≠ 20.

The z-statistics is given by (sample mean - hypothesized mean) divided by (standard deviation divided by the square root of the sample size).

i.e.

[tex]z= \dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}[/tex]

x = 26,  [tex]\mu[/tex] = 20, [tex]\sigma[/tex] = 7 and n = 15 putting the values in the question we will get the z-score value.

[tex]z = \dfrac{26-20}{\dfrac{7}{\sqrt15}}[/tex]

z = 6 / 1.807

z = 3.32
