The probability that exactly 2 seeds will don't grow will be equal to 0.193.

Probability is calculated as the proportion of favorable events to all potential scenarios of an event. The proportion of positive results, or x, for an experiment with 'n' outcomes can be expressed.

As per the given information in the question,

P(2 don't grow) = P(8 will grow)

Use the formula given below,

P(X = r) = [tex]^nC_r\ p^r(1-p)^{n - r}\\[/tex]

P(X = 8) = ¹⁰C₂ (0.9)⁸(0.1)²

= 45 × 0.43 × 0.01

= 0.193

Answer:

(10, 15)

Step-by-step explanation:

To get the origin of the equation 2y+3x = 10, we need to get the x and y-intercept of the line.

x-intercept occurs at y = 0

If y = 0

2(0)+3x =10

3x =10

x = 10/3

x = 1.33

y-intercept occurs at x = 0

If x = 0

2y+3(0) =10

2y =10

y = 10/2

y = 5

Hence the coordinate at the origin is (10/3, 5). If this coordinate is dilated by 3, the required coordinate will be at (10/3*3, 5*3) = (10, 15)

Hence the required coordinate is (10, 15)

Step-by-step explanation:

the number is 15 as solved or proved in the figure above

Answer:

Step-by-step explanation:

V = pi r^2 h

V = 187

pi = 3.14

r = 3

h = ?

187 = 3.14 * 3^2 * h

187 = 3.14 * 9 * h

187 = 28.26 * h

187 / 28.26 = h

h = 6.62

Answer:

The height of cylinder is 6.61 inches.

Step-by-step explanation:

Volume of cylinder = π × r ² × h

Where,

Using Formula

Volume of cylinder = π × r ² × h

Substitute the values

187 inches ³ = π × ( 3 inches ) ² × h

Using π = 3.14

187 inches ³ = 3.14 × 9 inches ² × h

multiply

187 inches ³ = 28.26 inches ² × h

Divide , we get

187 inches ³ / 28.26 = h

6.61 inches = h

Therefore, The height of cylinder is 6.61 inches.

Answer:

A

Step-by-step explanation:

The position of an atom moving inside a cathode ray tube is given by the function:

[tex]f(t)=t^3-4t^2+3t[/tex]

Where f(t) is in meters and t is in seconds.

And we want to determine its instantaneous velocity at t = 2.5 seconds.

The velocity function is the derivative of the position function. Thus, find the derivative of the function:

[tex]f'(t)=3t^2-8t+3[/tex]

Then the instantaneous velocity at t = 2.5 will be:

[tex]f'(2.5)=3(2.5)^2-8(2.5)+3=1.75\text{ m/sec}[/tex]

Our answer is A.

Answer:

Instantaneous Velocity:

[tex]\longrightarrow\:\rm v = \dfrac{dt}{dy}[/tex]

[tex]\longrightarrow\:\rm v = \dfrac{d}{dy}( {t}^{3} - 4 {t}^{2} + 3t) \\ [/tex]

[tex]\longrightarrow\:\rm v = 3 {t}^{3 - 1} - 2.4 {t}^{2 - 1} + 3[/tex]

[tex]\longrightarrow\:\rm v = 3 {t}^{2} - 8 t + 3[/tex]

[tex]\longrightarrow\:\rm v = 3 {(2.5)}^{2} - 8 (2.5)+ 3[/tex]

[tex]\longrightarrow\:\rm v = 3 \times 6.25 - 20+ 3[/tex]

[tex]\longrightarrow\:\rm v = 18.75 - 20+ 3[/tex]

Answer: 132º

Step-by-step explanation:

Since <QSR is an inscribed angle, that means that the intercepted arc, which is arc QR, is twice the measure of that angle, which is 132º. Since <QPR is a center angle, it is equal to its center arc. So, <QPR is 132º.

Step-by-step explanation:

The equation of line

perpendicular to : [tex]x -3y =9[/tex]

Passes through [tex](3,5)[/tex]

We have:

[tex]x -3y =9[/tex]

Make y the subject

[tex]3y =x - 9[/tex]

Solve for y

[tex]y = \frac{x}{3} - 3[/tex]

Compare the above equation to [tex]y = mx + c[/tex]

[tex]m =\frac{1}{3}[/tex] ---- This represents the slope

Since the line is perpendicular to [tex]x -3y =9[/tex], then its slope is:

[tex]m_2 = -\frac{1}{m}[/tex]

[tex]m_2 = -\frac{1}{1/3}[/tex]

[tex]m_2 =-3[/tex]

The equation of the perpendicular line is:

[tex]y =m_2(x - x_1) + y_1[/tex]

Where:

[tex]m_2 =-3[/tex]

[tex](x_1,y_1) =[/tex] [tex](3,5)[/tex]

So:

[tex]y = -3(x - 3) + 5[/tex]

[tex]y = -3x + 9 + 5[/tex]

[tex]y = -3x + 14[/tex]
