Step-by-step explanation:

vol of cone=

[tex]\pi {r}^{2} \frac{h}{3} [/tex]

[tex]3.14 \times 16 \times \frac{11}{3} [/tex]

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:

65kg=143.30047 pounds and 1kg=2.20462262 pounds

Answer:

=b^2+(9+2)b+18

=b^2+9b+2b+18

=b(b+9)+2(b+9)

=(b+9)(b+2)

Step-by-step explanation:

Because the abscissa does not repeat with different ordinate (well, there's actually no repeating abscissa)

Answer:c

Step-by-step explanation:

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:

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

Answer:

( 2,0)

Step-by-step explanation:

The line crosses the Y intercept at the coordinates at (2,0)

Answer:

the y-intercept of the graph is 2

the ordered pair is (0,2)

Step-by-step explanation:

The y-intercept is the point where the line crosses the "y" line. Ordered pair are written (x,y)  (the x is always in the front)

So, if we look at the "y" line we can see they y point is a 2, and if we look at line "x", the 2 is "above" the point 0 on the line labeled x.

Answer:

$203,333

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:

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 18

Answer:

18

Step-by-step explanation:

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-

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
