Ricky made approximately 4 goal points for every 7 of his shots on goal. What is the probability that Ricky would make 2 goal points on two shots in a row during the season?

Answers

Given:

Ricky made approximately 4 goal points for every 7 of his shots on goal.

To find:

The probability that Ricky would make 2 goal points on two shots in a row during the season.

Solution:

Using the given information, the probability of a goal point on one shot is:

[tex]P(one\ goal)=\dfrac{4}{7}[/tex]

We need to find the probability that Ricky would make 2 goal points on two shots in a row during the season.

Since the both shots are independent events therefore,

[tex]P(Two\ goals)=P(one\ goal)\times P(one\ goal)[/tex]

[tex]P(Two\ goals)=\dfrac{4}{7}\times \dfrac{4}{7}[/tex]

[tex]P(Two\ goals)=\dfrac{16}{49}[/tex]

Therefore, the required probability is [tex]\dfrac{16}{49}[/tex].

Step-by-step explanation:

1) 1/2 x 3.14 x 35^2

1/2 x 3.14 x 1225

1/2 x 3846.5

A = 1923.25 yd^2

(3.14) (35)^2

3846.50 yd^2

3) P = d + (3.14)r^2

P = 70 + (3.14) (35)

P = 70 + 109.90

P = 179.90 yd

4) P = 2( l + w)

P = 2 (70 + 100)

P = 2 (170)

P = 340

To find x we have to basically do pythagoream theorem twice. Both the traingles share the same long side. The find the long side of the top traingle do, [tex]a^{2} +16^{2} =25^{2}[/tex], and we find the long side to be [tex]\sqrt{369}[/tex]. Using this we now plug it into the pythagoream theorem for the bottom triangle. [tex]\sqrt{369} ^{2} +x^{2} =22^{2}[/tex], and doing this out we find that x=[tex]\sqrt{115}[/tex] or about 10.7.

a click beetle abruptly releases elastic energy stored in its body to launch itself into the air. the function h(t)=-16t^2+12t represents the height h (in feet) of the click beetle t seconds after launching. the height of a second click beetle t seconds after launching is shown in the graph. which click beetle went higher?

Answers

Answer:

The first click beetle reaches a maximum height of 2.25 feet. From the graph, you can see that the second click beetle reaches a maxium height of between 1.5 and 1.6 feet. So, the first click beetle went higher.

A beetle reaches a maximum height of 2.25 meters after 2,25 seconds

How to determine the maximum height?

The function is given as:

h(t)=-16t^2+12t

Differentiate

h'(t)= -32t + 12

Set to 0

-32t + 12 = 0

Add 32t to both sides

32t = 12

Divide both sides by 32

t = 0.375

Substitute t = 0.375 in h(t)

h(0.375) = -16 * 0.375^2 + 12 * 0.375

Evaluate

h(0.375) = 2.25

The above means that a beetle reaches a maximum height of 2.25 meters after 2,25 seconds

The equation 3x – 2y = 18 is in slope intercept
form.

form.
(Use all lowercase letters when writing the answers)

Answers

Given:

The equation is:

[tex]3x-2y=18[/tex]

To find:

The slope intercept form of the given equation.

Solution:

Slope intercept form of a line is:

[tex]y=mx+b[/tex]

Where, m is slope and b is y-intercept.

We have,

[tex]3x-2y=18[/tex]

It is not in the slope intercept form.

We need to isolate variable y to get the slope intercept form.

The given equation can be rewritten as:

[tex]-2y=-3x+18[/tex]

[tex]y=\dfrac{-3x+18}{-2}[/tex]

[tex]y=\dfrac{-3x}{-2}+\dfrac{18}{-2}[/tex]

[tex]y=\dfrac{3}{2}x-9[/tex]

Therefore, the slope intercept form of the given equation is [tex]y=\dfrac{3}{2}x-9[/tex].
