Answer:

y=2/3

Step-by-step explanation:

Since y is in the denominator, we take it to the other side to make it the numerator. And 6 also changed sides which results in y=4/6. Reducing to lowest terms we get, y=2/3.

Given:

Cost = £ 800

Tax = 20%

To find:

The total cost

Solution:

Total cost = Cost + Tax

Tax = 20 % of cost

20 / 100 * 800

Tax = £ 160

Hence,

Total cost =  £ 800 + £ 160

Total cost = £ 960

Answer:

(a)

[tex]Pr(x = 0) = \frac{^7C_2}{45}[/tex]            [tex]Pr(x = 1) = \frac{^7C_1 * ^3C_1}{45}[/tex]            [tex]Pr(x = 2) = \frac{^3C_2}{45}[/tex]

(b)

[tex]E(x) = \frac{3}{5}[/tex]

Step-by-step explanation:

Given

[tex]n = 10[/tex] --- flashbulbs

[tex]k = 3[/tex] --- defective bulbs

[tex]r = 2[/tex] --- selected

Solving (a): The distribution of x

The total outcome is: [tex]^nC_r[/tex]

This gives:

[tex]^{10}C_2 = 45[/tex]

Having 3 defective bulbs means 7 are not.

When there is no defective bulb among the selected, the probability is:

[tex]Pr(x = 0) = \frac{^7C_2}{45}[/tex]

When 1 is defective:

[tex]Pr(x = 1) = \frac{^7C_1 * ^3C_2}{45}[/tex]

When both are defective

[tex]Pr(x = 2) = \frac{^3C_2}{45}[/tex]

So, the distribution is:

[tex]Pr(x = 0) = \frac{^7C_2}{45}[/tex]

[tex]Pr(x = 1) = \frac{^7C_1 * ^3C_1}{45}[/tex]

[tex]Pr(x = 2) = \frac{^3C_2}{45}[/tex]

Solving (b): The expected value

This is calculated as:

[tex]E(x) = \sum x * Pr(x)[/tex]

So, we have:

[tex]E(x) = x_1 * Pr(x_1) +x_2 * Pr(x_2) + ............... + x_n * Pr(x_n)[/tex]

The equation becomes:

[tex]E(x) = 0* Pr(x=0) +1* Pr(x=1) + 2 * Pr(x=2)[/tex]

[tex]E(x) = 1* Pr(x=1) + 2 * Pr(x=2)[/tex]

[tex]E(x) = Pr(x=1) + 2 * Pr(x=2)[/tex]

From the distribution in (a), we have:

[tex]E(x) = \frac{^7C_1 * ^3C_1}{45} + 2 * \frac{^3C_2}{45}[/tex]

[tex]E(x) = \frac{7 * 3}{45} + 2 * \frac{3}{45}[/tex]

[tex]E(x) = \frac{21}{45} + \frac{6}{45}[/tex]

[tex]E(x) = \frac{21+6}{45}[/tex]

[tex]E(x) = \frac{27}{45}[/tex]

Simplify

[tex]E(x) = \frac{3}{5}[/tex]

Answer:

[tex]P(x< 240) = 0.0521[/tex]

Step-by-step explanation:

Given

[tex]\bar x = 266[/tex]

[tex]\sigma = 16[/tex]

Required

[tex]P(x < 240)[/tex] --- pregnancy will last less than 240 days

First, calculate the z score

[tex]z = \frac{x - \bar x}{\sigma}[/tex]

Where:

[tex]x = 240[/tex]

So, we have:

[tex]z = \frac{240 - 266}{16}[/tex]

[tex]z = \frac{-26}{16}[/tex]

[tex]z = -1.625[/tex]

So:

[tex]P(x< 240) = P(z < -1.625)[/tex]

From z probability:

[tex]P(z < -1.625) = 0.052081[/tex]

[tex]P(z < -1.625) = 0.0521[/tex] --- approximated

So:

[tex]P(x< 240) = 0.0521[/tex]

Answer:

9.68*10^-10

Step-by-step explanation:

The problem above can be solved using the binomial probability relation :

Where ;

P(x = x) = nCx * p^x * q^(n-x)

n = number of trials = 25

p = 1/4 = 0.25

q = 1 - p = 0.75

x = 20

P(x > 20) = p(x = 21) + p(x = 22) +.. + p(x = 25)

Using the binomial probability calculator to save computation time :

P(x > 20) = 9.68*10^-10

Answer:

the volume of the solid is 1024/3 cubic unit

Step-by-step explanation:

Given the data in the question,

radius of the circular disk = 4

Now if the center is at ( 0,0 ), the equation of the circle will be;

x² + y² = 4²

x² + y² = 16

we solve for y

y² = 16 - x²

y = ±√( 16 - x² )

{ positive is for the top while the negative is for the bottom position }

A = b²

b = 2√( 16 - x² )           { parallel cross section }

A = [2√( 16 - x² )]²

A = 4( 16 - x² )

Now,

VOLUME = [tex]\int\limits^r -rA dx[/tex]

= [tex]\int\limits^4_4 {-4(16-x^2)} \, dx[/tex]

= 4[ 16x - (x³)/3 ]           { from -4 to 4 }

= 4[ ( 64 - 64/3 ) - (-64 = 64/3 0 ]

= 4[ 64 - 64/3 + 64 - 64/3 ]

= 4[ (192 - 64 + 192 - 64 ) / 3 ]

= 4[ 256 / 3 ]

= 1024/3 cubic unit

Therefore,  the volume of the solid is 1024/3 cubic unit

Answer:

Profit of one small cake =£108.08

Step-by-step explanation:

small : medium : large = 5 : 7 : 12

Sum of the ratio = 5 + 7 + 12 = 24

Total number of cakes = 216

Number of small cakes

                                 [tex]= \frac{5}{24} \times 216 = 5 \times 9 = 45[/tex]

Number of medium cakes

                                 [tex]= \frac{7}{24} \times 216 = 7 \times 9 = 63[/tex]

Number  of large cakes

                                 [tex]=\frac{12}{24} \times 216 = 12 \times 9 = 108[/tex]

Let profit of one small cake be = x

Profit of medium cake is twice profit of small cake = 2x

Profit of large cake is thrice profit of small cake = 3x

Total profit = £648.45

x + 2x + 3x = £648.45

6x = 648.45

x = 108.075

Therefore , profit of one small cake =£108.08

Step-by-step explanation:

216 cakes =5+7+12

=24

5 = 216 cakes ÷ 24 × 5

= 45 cakes

7 = 216 cakes ÷ 24 × 7

= 63 cakes

12 = 216 cakes ÷ 24 × 12

=108 cakes

£648.45 ÷ (45+63+63+108+108+108)cakes = £648.45 ÷ 495

= £1.31

45 cakes × £1.31 = £58.95

In 10 ways can a supermarket manager display 5 brands of cereals

in 3 spaces on a shelf.

Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant. You can choose the components of combos in any order. Permutations and combinations can be mixed up.

Given:

Total brands of cereals= 5

Using Combination, C(n, r)

= n!/ r! (n- r)!

So, the number of ways

= C(5, 3)

= 5!/(3!(5-3)!) 5

= 5 x 4 x 3! / 3! x 2!

= 5 x 4 /2

= 10

Thus, the total number of ways is 10.

The time-mean speed of the minivans is of 105.8 seconds.

Step-by-step explanation:

Mean of a data-set:

The mean of a data-set is the sum of all values in the data-set divided by the number of values.

Five minivans, times of: 98.0, 108.0, 113.0, 108.0, 102.0, in seconds.

Thus, the mean is:

[tex]M = \frac{98 + 108 + 113 + 108 + 102}{5} = 105.8[/tex]

The time-mean speed of the minivans is of 105.8 seconds.
