Answer:

x=96

Step-by-step explanation:

Since x varies inversely as [tex]y^{2}[/tex], x*[tex]y^{2}[/tex] = k

sub x=6, y=8 into x[tex]y^{2}[/tex] = k  =>  6*64 = k => k= 384

so when y =2, x = 384/ ([tex]2^{2}[/tex]) = 384/4 = 96

Answer:

The value is  [tex]P(X = 1 ) = 0.0948[/tex]

Step-by-step explanation:

From the question we are told that

  The  the probability that the Smudgy Press book pages have zero  errors   [tex]p = 0.90[/tex]

Gnerally the probability distribution for Poisson distribution is  

        [tex]P(X = x) = \frac{\lambda ^x * e^{-\lambda}}{x!}[/tex]

Gnerally the probability that the Smudgy Press book pages have zero  errors is mathematically represented as

       [tex]P(X = 0) = \frac{\lambda ^0 * e^{-\lambda}}{0!} =p= 0.90[/tex]

=>    [tex]e^{-\lambda} =p= 0.90[/tex]

taking natural  log of both sides

       [tex]ln (e^{-\lambda}) = ln(0.90)[/tex]

=>     [tex]-\lambda = -0.1054[/tex]

=>   [tex]\lambda = 0.1054[/tex]

Generally the probability that a randomly selected page contains exactly one error is mathematically represented as

         [tex]P(X = 1 ) = \frac{\lambda ^1 * e^{-\lambda}}{1!}[/tex]

=>       [tex]P(X = 1 ) = \frac{0.1054 ^1 * e^{-0.1054 }}{1!}[/tex]

=>       [tex]P(X = 1 ) = 0.0948[/tex]

2 lip glosses

explanation

4x8= 32

50-32=18

2 lipglosses would be $20

32+20=52

52>50 meaning she qualifies for free shipping

4 eye shadows -- 8 x 4 = $32

lip glosses $10 -- 32 + 10 + 10 = $52

to qualify for free shipping, wendy needs to buy 2 lip glosses.

Answer:

66%

Step-by-step explanation:

According to a study conducted by the World Health Organization, 66% of adults in high-income countries are overweight. Even though the exact reason for this is not known, there are two main theories. The first one is that individuals make more money and therefore have extra income to spend on food, mainly junk food such as snacks, ice cream, candy, etc. The second theory is that due to the large number of work hours that individuals in these countries have to put in, they tend to eat more often at fast food places such as McDonald's and Burgerking.

This question is incomplete, the complete question is;

find the critical points and classify them as local maxima, local minima, saddle points, or none of these.

f(x,y) = (x + y)(xy + 1)

Answer:

(x,y) = (-1, 1), (1, -1) area critical points

f(xx) =2y, fyy =2x,f(xy) =2x + 2y, D = f(xx)fyy - f(xy² )

at (-1, 1)

f(xx) = 2 ,fyy =-2,f(xy) = 0, D = -4 < 0 saddle point

at (1, -1)

f(xx) = -2, fyy =2,f(xy) =0, D = -4 < 0 saddle point

Step-by-step explanation:

Given that;

f(x,y) = (x + y)(xy + 1)

f(x,y) =x²y + xy² + x + y

for critical points fx =0 ,fy =0

fx = 2xy + y² + 1 = 0, fy = x² + 2xy + 1 = 0

2xy + y² + 1 = 0, x²+ 2xy + 1 = 0

2xy + y² + 1 - x² - 2xy - 1 = 0

x² = y²

=> x = y, x = -y

2xy + y² + 1 = 0, x = y

2yy + y² + 1 = 0

3y² = -1 , no solution

2xy + y² + 1 = 0, x = -y

-2yy + y² + 1 = 0

=> -y2 + 1 = 0

=> y = -1, y = 1  

y = -1 => x = 1, y = 1 => x = -1  

(x,y) = (-1, 1), (1, -1) area critical points

f(xx) =2y, fyy =2x,f(xy) =2x + 2y, D = f(xx)fyy - f(xy² )

at (-1, 1)

f(xx) = 2 ,fyy =-2,f(xy) = 0, D = -4 < 0 saddle point

at (1, -1)

f(xx) = -2, fyy =2,f(xy) =0, D = -4 < 0 saddle point

Answer:

Step-by-step explanation:

The question is incomplete:

You have space in your garden for 60 small flowering bulbs. Crocus bulbs cost $0.25 each and daffodil bulbs cost $0.85 each. Your budget allows you to spend $39.00 on bulbs. How many crocus bulbs and how many daffodil bulbs can you buy?

Answer:

You can buy 20 crocus bulbs and 40 daffodil bulbs.

Step-by-step explanation:

From the information provided you can write the following equations:

x+y=60 (1)

0.25x+0.85y=39 (2), where:

x is the number of crocus bulbs and y is the number of daffodil bulbs.

First, you can solve for x in (1):

x=60-y (3)

Then, you can replace (3) in (2):

0.25(60-y)+0.85y=39

15-0.25y+0.85y=39

0.60y=39-15

y=24/0.60

y=40

Finally, you can replace the value of y in (3) to find the value of x:

x=60-40

x=20

According to this, the answer is that you can buy 20 crocus bulbs and 40 daffodil bulbs.

Answer:

Step-by-step explanation:

their difference is 16

x - y = 16

⇒ x = 16 + y

their ratio is 5:7

x/y = 5/7

substitute:

(16 + y)/y  = 5/7

16 + y = (5y)/7

112 + 7y = 5y

2y = -112

y = -56

x - y = 16, so x -  -56 = 16,

x+56 = 16

x = 16-56

x = -40

Answer:

The answer is 9

Step-by-step explanation:

The number marbles were neither red nor yellow is 9.

Given that, a bag of 28 marbles 1/4 the marbles were red and 3/7 were yellow.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Now, the number of red marbles = 1/4 × 28

= 7

The number of yellow marbles = 3/7 × 28

= 12

Total number of red and yellow marbles = 7+12 = 19

Neither red nor yellow = 28-19=9

Therefore, the number marbles were neither red nor yellow is 9.

Answer:

Airplane covers a distance of approximately 50.265 feet in 4 minutes.

Step-by-step explanation:

From Rotation Physics we know that angular speed is the number of revolutions done by a particle at a given time. If the boy is twirling a model airplane at constant speed, then we calculate such variable as follows:

[tex]\dot n = \frac{n}{t}[/tex] (Eq. 1)

Where:

[tex]\dot n[/tex] - Angular speed, measured in revolutions per minute.

[tex]n[/tex] - Number of revolutions done by airplane, measured in revolutions.

[tex]t[/tex] - Time, measured in minutes.

Now we clear the number of revolutions done by airplane within expression:

[tex]n = \dot n \cdot t[/tex]

If we know that [tex]\dot n = 0.5\,\frac{rev}{min}[/tex] and [tex]t = 4\,min[/tex], then we get that number of revolutions is:

[tex]n = \left(0.5\,\frac{rev}{min} \right)\cdot (4\,min)[/tex]

[tex]n = 2\,rev[/tex]

The airplane made two revolutions in four minutes.

Now, the distance covered by the airplane ([tex]s[/tex]), measured in feet, is calculated by means of the equation below:

[tex]s = 2\pi\cdot l\cdot n[/tex]

Where:

[tex]l[/tex] - Length of the string, measured in meters.

[tex]n[/tex] - Number of revolutions done by airplane, measured in revolutions (dimensionless).

If we get that [tex]n = 2\,rev[/tex] and [tex]l = 4\,ft[/tex], then the distance covered by the airplane in 4 minutes is:

[tex]s = 2\pi\cdot (4\,ft)\cdot (2\,rev)[/tex]

[tex]s \approx 50.265\,ft[/tex]

Airplane covers a distance of approximately 50.265 feet in 4 minutes.
