Answer:

X : ___ 0 ____ 1 _____ 2 _____ 3 _____ 4

P(x): _ 1/16 __ 1/4 ____ 3/8 ____ 1/4 ____ 1/16

Step-by-step explanation:

Given the listed possible occurrence of boys and girls :

B = boys ; G = girls

BBBB, BBBG, BBGB, BGBB, GBBB, BGBG, GBGB, BGGB, GBBG, BBGG, GGBB, BGGG, GBGG, GGBG, GGGB, and GGGG

Let x = distribution of girls

P = required outcome / Total possible outcomes

For :

x = 0 ;(BBBB) = 1

P(x) = 1/16

x = 1 ; (BBBG, BBGB, BGBB, GBBB) = 4

P(x) = 4 / 16 = 1/4

P(x = 2) ; (BGBG, GBGB, BGGB, GBBG, BBGG, GGBB) = 6

P(x) = 6 / 16 = 3/8

P(x = 3) ; (BGGG, GBGG, GGBG, GGGB) = 4

P(x) = 4 / 16 = 1/4

P(x = 4) ; (GGGG) = 1

P(x) = 1 / 16

X : ___ 0 ____ 1 _____ 2 _____ 3 _____ 4

P(x): _ 1/16 __ 1/4 ____ 3/8 ____ 1/4 ____ 1/16

Answer:

x = -22/3 and y = -1

Step-by-step explanation:

First, simplify the equation 12x + 20y = -108 by dividing both sides by 4:

3x + 5y = -27

now, you can subtract the two equations:

3x + 5y = -27

- (3x - 12y = -10)

17y = -17

y = -1

plug y = -1 into the equation 3x - 12y = -10

3x - 12 *(-1) = -10

3x + 12 = -10

3x = -22

x = -22/3

Answer:

-(22/3,-1)

Step-by-step explanation:

Answer:

50

Step-by-step explanation:

Let's say the smaller number is x then

x + x + 2 = 98

2x+2 = 98

2x = 96

x = 48

==> 48, 50

The sum of two consecutive even integers is 98 has 50 as larger number.

Given that the sum of two consecutive even integers is 98, we need to find the larger number,

Let's denote the two consecutive even integers as x and x + 2. According to the given information, their sum is 98.

So we can write the equation:

x + (x + 2) = 98

Simplifying the equation:

2x + 2 = 98

Subtracting 2 from both sides:

2x = 96

Dividing both sides by 2:

x = 48

Therefore, the larger number (x + 2) is:

48 + 2 = 50

So, the larger number is 50.

Answer:

1.56%

Step-by-step explanation:

A standard deck of cards has 52 cards, and 13 of these are hearts, as there are 4 suits, and 52/4=13. This means the probability of choosing a heart card from a deck of cards is 1/4, or 25%. Now to find the probability of doing this from 3 decks in a row, we simply cube 1/4 to get 1/64, and in percentage this is ~1.56%.

Answer: 1.56%

[tex]R = 45x[/tex]

Required

The break even point

To do this, we make use of:

[tex]R =C[/tex]

Answer:

the answer is (3 4)

Step-by-step explanation:

Answer:

(a) 1) When V = 1000 L, the height of the liquid in the tank is approximately 62 cm

2) When V = 5,000 L, the height of the liquid in the tank is approximately 106 cm

3) When V = 10,000 L, the height of the liquid in the tank is approximately 202 cm

b) The drawing of the spherical tank showing the height of the liquid level for each volume created with Microsoft Excel is attached

Step-by-step explanation:

(a) The height of the spherical tank = 3 m

The diameter of the spherical tank, d = 3 m

The capacity of the spherical tank = 14,000 L

The volume of a sphere, V = (4/3) × π × r³ =

Where, r = d/2

∴ r = 3 m/2 = 1.5 m

V = (4/3) × π × (1.5)³ ≈ 14.1371669412 m³

Using calculus, we have;

[tex]V = 2 \times \pi \times \int\limits^r_{0} {(r^2 - y^2)} \, dx = 2 \times \pi \times \left[r^2 \cdot y - \dfrac{y^3}{3} \right]^y_0[/tex]

For the two halves, we have;

[tex]V = \pi \times \left[r^2 \cdot y - \dfrac{y^3}{3} \right]^{\dfrac{y}{2}} _0 + \pi \times \left[r^2 \cdot y - \dfrac{y^3}{3} \right]^y_{\dfrac{y}{2}}[/tex]

[tex]V = 2 \times \pi \times \left[y^3- \dfrac{y^3}{3} \right]^y_0 = \dfrac{4 \cdot \pi \cdot y^3}{3}[/tex]

1) For V = 1000 L, we have;

[tex]1000 \ L = \dfrac{4 \cdot \pi \cdot y^3}{3}[/tex]

1000 L =

When V = 1000 L, we have;

[tex]y = \sqrt[3]{\dfrac{3 \times 1 \, m^3}{4 \times \pi } } \approx 0.62 \ m[/tex]

The liquid level, y ≈ 0.62 m = 62 cm

2) When V = 5,000 L, we have;

[tex]y = \sqrt[3]{\dfrac{3 \times 5 \, m^3}{4 \times \pi } } \approx 1.06 \ m[/tex]

The liquid level, y ≈ 1.06 m = 106 cm

3) When V = 10,000 L, we use the height of the unfilled volume at the top which is the volume of the sphere less the 10,000 L as follows;

For the volume of the sphere of 14,000 L, we have;

Volume at the top = 14,000 L - 10,000 L = 4,000 L = 4 m³

Therefore

[tex]y_{top} = \sqrt[3]{\dfrac{3 \times 4 \, m^3}{4 \times \pi } } \approx 0.985 \ m[/tex]

The height of the liquid in the tank, y = d - [tex]y_{top}[/tex]

∴ y = 3 m - 0.985 m = 2.015 m

The liquid level, y ≈ 2.015 m = 201.5 cm ≈ 202 cm

b) Please find attached the drawing of the spherical tank created with Microsoft Excel

a) (i) The level line for 1000 liters is set at a height of 0.486 meters.

(ii) The level line for 5000 liters is set at a height of 1.203 meters.

(iii) The level line for 10000 liters is set at a height of 1.926 meters.

b) The sphere is represented by the equation [tex]x^2+(y-1.5)^{2} = 2.25[/tex] and the level lines are represented by the linear functions [tex]y = 0.486[/tex], [tex]y = 1.203[/tex] and [tex]y = 1.926[/tex]. Please see the second image attached.

a) First, we derive an expression for the volume of a spherical section ([tex]V[/tex]), in cubic meters, in terms of tank radius ([tex]R[/tex]), in meters, and liquid height ([tex]h[/tex]), in meters. The volume can be found by using the slicing method integral equation:

[tex]V = \int\limits^{H}_{0} {A(h)} \, dh[/tex] (1)

Where:

If we know that [tex]A = \pi\cdot [R^{2}-(R-h)^{2}][/tex], then the volume formula is:

[tex]V = \pi\int\limits^H_0 {h\cdot (2\cdot R-h)} \, dh[/tex]

[tex]V = 2\pi\cdot R\int\limits^{H}_{0} {h} \, dh - \pi \int\limits^{H}_{0} {h^{2}} \, dh[/tex]

[tex]V = \pi\cdot R\cdot H^{2}-\frac{\pi\cdot H^{3}}{3}[/tex]

Then we obtain the following third order polynomial:

[tex]\frac{\pi\cdot H^{3}}{3}-\pi\cdot R\cdot H^{2}+V = 0[/tex] (2)

Now we proceed to solve numerically for each case:

[tex]H = 0.486\,m[/tex]

The level line for 1000 liters is set at a height of 0.486 meters. [tex]\blacksquare[/tex]

[tex]H = 1.203\,m[/tex]

The level line for 5000 liters is set at a height of 1.203 meters. [tex]\blacksquare[/tex]

[tex]H = 1.926\,m[/tex]

The level line for 10000 liters is set at a height of 1.926 meters. [tex]\blacksquare[/tex]

b) The sphere is represented by the equation [tex]x^2+(y-1.5)^{2} = 2.25[/tex]level lines are represented by the linear functions [tex]y = 0.486[/tex], [tex]y = 1.203[/tex] and [tex]y = 1.926[/tex]. By a graphing tool we have the following result. [tex]\blacksquare[/tex]

Answer:

18 pounds of beef.

Step-by-step explanation:

For every 0.5 cups of breadcrumbs there's 2 pounds of beef.

0.5 x 9 = 4.5

9 x 2 = 18 or 2 x 9 = 18

multiples of two: 2 4 6 8 10 12 14 16 18

This shows that when we multiply 2 nine times we get 18!
