Answer:

[tex]\frac{1}{120}[/tex]

Step-by-step explanation:

To solve such a problem you need to simulate a situation in which this could happen in three picks and then make sure your equation takes into account that all three picks take place at the same time. One such situation could look like this:

1) At the start, the probability of picking one rotten apple with one pick is 2 out of 16 which 2/16.

2) After picking the first apple you have 15 apples left of which only 1 is rotten. So the chance to pick the second rotten apple is 1/15.

3) After you picked the second rotten apple you want the third one in the set to be good. As you are left with 14 apples of which all 14 are good, the probability of picking a good one is 14/14.

Now, because you are interested in ALL those 3 things happening at the same time, you need to multiply the probabilities. So this gives you the answer of:

[tex]\frac{2}{16} *\frac{1}{15} *\frac{14}{14} = \frac{1}{8} *\frac{1}{15} *1 = \frac{1}{120}[/tex]

You can achieve the same result if your picks are in a slightly different order. The result won't change as long as the outcome is the same (set of 2 rotten apples and 1 good apple). So if you first pick a rotten apple (2/16), then you happen to pick a good apple (14 out of 15 left are good so 14/15) and then pick the second rotten apple last (1/14) you will see it's gives the same result because you also end up with 2 rotten and 1 good apples:

[tex]\frac{2}{16} * \frac{14}{15} * \frac{1}{14} = \frac{1}{8} * \frac{1}{15} = \frac{1}{120}[/tex]

Step-by-step explanation:

I assume you need the slope-intercept form

y = ax + b

"a" being the slope, "b" being the y-intercept (the y value when x = 0).

since we have the slope and a point, we can start with the point-slope form

y - y1 = a(x - x1)

"a" is again the slope, (x1, y1) is a point on the line

so, we have

y - -7 = 3(x - -4)

y + 7 = 3(x + 4) = 3x + 12

and from there now the final equation :

y = 3x + 5

The value of a and b based on the given table when the number of pairs of tiles is 2 is given by 30 cm and 40 cm respectively.

When,

number of pairs of tiles is 1

Width of each tile = 20 cm

Length of each tile = 30 cm

number of pairs of tiles is 3

Width of each tile = 40 cm

Length of each tile = 50 cm

number of pairs of tiles is 2

Width of each tile, a = 20 cm + width of each tile

= 20 cm + 10 cm

= 30 cm

a = 30 cm

Length of each tile, b = 30 cm + width of each tile

= 30 cm.+ 10 cm

= 40 cm

b = 40 cm

The value of y so that WX ⊥ YZ is y = 4 .

In the question ,

it is given that

the line WX is perpendicular to line YZ

and the end points of WX is W(2,-3) and X(-4,9)

and the end points of YZ is Y(5,y) and Z(-1,1) .

let the slope of line WX = m₁

and slope of line YZ = m₂ .

we know that when two lines are perpendicular , then

m₁ * m₂ = -1

m₁ = (9-(-3))/(-4-2)

and m₂ = (1-y)/(-1-5)

Substituting the values of m₁ and m₂ in the equation m₁ * m₂ = -1  ,

we get

(9-(-3))/(-4-2) * (1-y)/(-1-5) = -1

(9+3)/(-6) * (1-y)/(-6) = -1

12/(-6) * (1-y)/(-6) = -1

-2* (1-y) = 6

Leaping deer company purchased a tractor at a cost of $440,000. The tractor has an estimated residual value of $40,000 and an estimated life of 8 years, or 12,000 hours of operation. The tractor was purchased on January 1, 2015 and was used 2,400 hours in 2015 and 2,200 hours in 2016.

To find out which method of depreciation will produce maximum depreciation, Depreciation expense for 2018 shall be calculated using all methods.

1) Double-declining balance method: Under this method, depreciation is charged to an accelerated rate to the asset by applying double depreciation instead of a regular depreciation rate. This rate is applied to the value of the depreciable assets.

Depreciable Value of Tractor = Gross Value - Salvage Value = $240,000 - $40,000 = $200,000

The regular rate of depreciation = 100% / Life of Tractor = 100% / 8 Years = 12.5%

Double-declining rate of depreciation = Regular rate X 2 = 12.5 % X 2 = 25%

Depreciation expense for 2018 = Depreciable value of tractor X Dobule-decling rate

= $200,000 X 25%

= $50,000

Depreciation expense as per double-declining method = $50,000

2) Straight-line method: Under this method, the value of the depreciable asset is spread over the useful life of the asset evenly.

Depreciation for 2018 = Useful life of Tractor / Useful life

= $200,000 / 8 Years

= $25,000

Depreciation expense as per straight line method = $25,000

3) Units of production method: Under this method, the depreciable value of assets is depreciated with the level of usage with respect to the overall capacity of assets with respect to usage. Hence, more usage shall lead to higher depreciation.

Total hours available during the life of asset = 12,000

Depreciation to be charged for each hour of usage = Depreciable value / Total hours

= $200,000 / 12,000 Hours

= $16.67 per hour

Depreciation for 2018 = Total hours of usage in 2018 X Depreciation per hour

= 3,800 Hours X $16.67

= $63,346

Depreciation under units of production method = $63,346.

Hence, Highest amount of depreciation is produced under units of production method as tractor has been used for more than one-third of its usage hour capacity. As the other two methods do not take into account the level of usage, their depreciation is just based on time. Hence, Depreciation under the unit production method is highest.

This means the 500 ft is the side adjacent to 90 degrees and 1600 ft is the hypotenuse. Sorry if it's not clear!)

Step-by-step explanation:

[tex]500^{2} +b^2=1600^2\\250000+b^2=2560000\\b^2=2560000-250000\\b^2=2310000\\\sqrt{b^2}=\sqrt{2310000}\\ b=1519.87[/tex]

Because we know the sum of the interior angles should be 180, we can use this to create an equation to solve for x.

60+(7x+3)+(180-20x)=180

Simplify to find that x = 5

If you're confused about where the 180-20x comes from:

The line it lays on is straight, meaning the angle it creates is 180 degrees.

Thus, 180 - known angle = unknown angle.

Answer:

the answer is c, x=5

Step-by-step explanation:

now, if we look at the pic, there is already one angle given.

and we know that sum interior angles of a triangle must be 180;

so the sum of the other two angles is: angle 2 +angle 3=180-60.

now, let's pick any number and put it into x.

first, if we put 15 into x: 7(15)+5=120,

so 180-(120+60)=0. and for there is another angle, it is invalid.

if we put 6: 7(6)+5=47,

180-(60+47)=73.

let's look at the third angle.

for x=6, the angle UBI is 120°. and we also know that the sum of angles on a horizontal line is always 180°, so 180-120=60, and for the third angle is NOT 73°, this one is also invalid.

if x=5: 7(5)+5=40, 180-(60+40)=80.

the angle UBI= 100°, 180-100=80°;

for 80°+60°+40° equals 180°, the answer c is correct.

Answer:

∴ Shaquana bought 7 candies and 6 pretzels.

Step-by-step explanation:

Suppose all the snacks she bought were candies.

13 × $5 = $65

$65 - $53 = $12

$5 - $3 = $2

$12 ÷ $2 = 6 pretzels

∴ Number of candies Shaquana bought

= 13 snacks - 6 pretzels

= 7 candies

Answer:

6 pretzels and 5 candies

Step-by-step explanation:

Let c be the number of candies and p the number of pretzels.

We can determine the total cost by multiplying the candy price by it's price, $5/candy.  That would be $5*c.  We can do the same for the pretzels:  $3*p.

Thje total spent is:    ($5)c + ($3)p = $53.  Since the $ sign cancels out, let's rewrite this to simplify:   5c + 3p = 53.

We know that c + p = 13

Rearrange this to c = 13-p and then substitute this definition of c in the first equation:

5c + 3p = 53

5(13-p) +3p = 53

65 - 5p + 3p = 53

-2p = - 12

p = 6  Shaquana brought 6 pretzels.

Since c + p = 13, this means she bought 7 candies.

Check to see if this works:

Do 6 pretzels and 7 candies cost $53?

 (6 prezels)*($3/pretzel) =  $18

 (7 candies)*($5/candy) =  $35

               Total                =  $53  YES

Caroline leaves her house and walks north 6 blocks. She turns and heads east 8 blocks until she reaches Mattie’s house.

The shortest distance between Caroline's and Mattie's house is 10 blocks.

If we assume this as a right angle triangle then height (BA) is 6 blocks long and base (BC) is 8 blocks

long.

Then, the shortest distance between Caroline's and Mattie's house will be the hypotenuse (AC) of this

triangle.

So, by applying Pythagoras theorem:

[tex](AC)^{2} = (BA)^{2} = (BC)^{2} = (6)^{2}+(8)^{2}[/tex] = 36+64 = 100

Thus, AC = [tex]\sqrt{100}[/tex] = 10 blocks.
