Can you help me solve this

Answer:

x=1/2 or x=0.5

Step-by-step explanation:

14=18x+8 so 18x =6 so x=1/2

Answer:

x = 1/3

Step-by-step explanation:

14 = 18x + 8

Subtract 8 from both sides.

6 = 18x

Divide both sides by 18.

6/18 = x

Simplify.

1/3 = x

Answer:

Ok so the area of the frame is 18*12 = 216cm^2

Let’s suppose the width of the frame is x

The total area (painting and frame) is (2x+18)(2x+12) and this is equal to 432

4x^2 + 60x + 216 = 432

4x^2 + 60x - 216 = 0

x^2 + 15x - 54 = 0

(x+18)(x-3) = 0

Therefore x = {-18,3}

Since width of the frame has to be positive, the width has to be 3cm Step-

Step-by-step explanation:

Computation for the break-even in sales dollars for Division Q

First step is to compute the Segment Contribution Margin ratio

Using this formula

Segment Contribution Margin ratio = Segment contribution margin ÷ Segment sales

Let plug in the formula

Segment Contribution Margin ratio= $ 175,980÷ $ 419,000

Segment Contribution Margin ratio= 0.42

Last step is to find the break-even in sales dollars for Division Q using this formula

Break-even in sales dollars = Segment traceable fixed expenses ÷ Segment Contribution Margin ratio

Let plug in the formula

Break-even in sales dollars= $85,400÷ 0.42

Break-even in sales dollars=$203,333

Therefore the break-even in sales dollars for Division Q is $203,333

Answer:

u = 65/7

Step-by-step explanation:

u/5 = 13/7

Using the cross product

7u = 5*13

7u = 65

Divide each side by 7

7u/7 = 65/7

u = 65/7

Answer:

Step-by-step explanation:

Let the measure of its supplementary angle be x

Since they are supplementary , it means that the sum of their angles add up to 180°.

To find x add up subtract 126.6 from 180

We have

x = 180 - 126.6

We have the final answer as

I just answered the question.

Answer:

18

Step-by-step explanation:

The tens digit a is cubed (a³ ) still less than the biggest possible 1 -digit number . It can be only 0 or 1 , so even 2³ =8 ( in such case the unit digit is 15,- that's  not possible) .

0 can not be the the first digit in 2 digit number. So the only possible tens digit is 1. So the unit number is 1+7=8.

Answer:

it will be in the thousands  place for sure

Step-by-step explanation:

hope that helps =) i forgot there were a decimal point

Answer:

The place value of 5 in "123.465" is the thousandths

Step-by-step explanation:

The reason for this is because the "5" is 3 points behind the decimal, making it in the thousanths place.

Answer:

(a) Hypergeometric distribution

(b) 0.785384...

Step-by-step explanation:

(a) looking at the question, we see that [tex]X = \in \{0, ... , 10 \}[/tex], suppose Evans studied s key terms, this implies that he has not studied 100 - s key terms. Suppose [tex]k = \in \{0, ... , 10 \}[/tex] if X = k, then k out of the s key terms he had studied appeared. But 10 - k out of 100 - s key terms he hasn't studied appeared. Thus X is an Hypergeometric distribution, X~HGeom(s, 100 - s, 10) with PMF:

[tex]P_{x}(k) = P(X = k)[/tex]

Answer:

3f+6

Step-by-step explanation:

To solve this, we combine like terms which are in this case 4f and f.  4f-9-f+15 is (4f-f)+(-9+15), which we simplify to 3f+6.

Answer:

x1= -4/3 and x2= 0

Step-by-step explanation:

Answer:

a.  P(x = 3) = 0.061313

b. The expected number of radio blackouts = 4

c.  It is not possible to determine the next radio blackout

d. P(x = 4) = 0.19537

Step-by-step explanation:

From the given information:

Using a Poisson process to model the phenomenon:

Since minor radio blackouts occur, on average, twice per year.

Then:

[tex]\lambda = 2 \ years[/tex]

From question (a)

time t = 1/2 (i.e half of the year)

Let x be the random variable that denotes the probability that 3 events will happen in the rest of the year.

Then:

[tex]P(x = 3) = \dfrac{e^{-\lambda t} \times (\lambda t)^x}{x!}[/tex]

[tex]P(x = 3) = \dfrac{e^{-2* 0.5} \times (2 * 0.5)^3}{3!}[/tex]

P(x = 3) = 0.061313

b).

The number of radio blackouts  we expect to see in two years can be estimated as follows:

we know that:

t = 2 years

E(x) = λ × t

E(x) = 2 × 2

E(x) = 4

The expected number of radio blackouts = 4

c).

The amount of time we need to wait given that the probability of seeing the next radio blackout is at least 0.5 is as follows:

Here, the time (t) = ???

Thus:

P(x =1) = 0.5

[tex]P(x = 1) = \dfrac{e^{-\lambda t} \times (\lambda t)^x}{x!} = 0.5[/tex]

[tex]\dfrac{e^{-\lambda t} \times (\lambda t)^x}{x!} = 0.5[/tex]

Thus, it is not possible to determine the probability (50%) of seeing the next radio blackout.

d)

The probability that the time to the 4th blackout is at most 2 years can be computed as follows:

Here;

x =4 , t = 2

Thus:

[tex]P(x = 4) = \dfrac{e^{-4 } \times (4)^4}{4!}[/tex]

P(x = 4) = 0.19537
