(d) Let p represent the probability of a successful long hit. What values of p will make the long hit better than the short hit

seropon [69]

Answer:

The probability of successful long hit is greater than 0.7083

Step-by-step explanation:

Solution

The expected value for long hit is given below

P (successful hit) * 4.2 + P (Unsuccessful hit) *5.4

so,

= P * 4.2 + (1-p) * 5.4

= 5.4 - 1.2p

Now,

If the expected value of long hit is less than that of the short it

Then,

5.4 - 1.2p <4.55

P> (5.4 - 4.55)/1.2

P> 0.7083

Therefore the probability of successful long hit is greater than 0.7083

Note:

Due to my research and findings to this example, the complete question for is attached below, i solved or Question 2(d) only

A sphere has a radius of 5 inches. What is its volume?

jarptica [38.1K]

Given ↓

Radius of sphere = 5 in

The volume of the sphere

<h3>Calculations ↓</h3>

$\blue{\boxed{\mathsf{V=\frac{4}{3} \pi r^3}}$

↑ formula for volume of a sphere

r = 5 in

Plug in the value of r and solve :

$\blue{\boxed{\mathsf{V=\frac{4}{3}\pi (5)^3}}}$

Simplify as follows :

$\blue{\boxed{\mathsf{V=\frac{4}{3}\pi *125} }}$

$\blue{\boxed{V=\frac{4}{3} *392.7}}$

Final Step :

$\blue{\boxed{\pmb{V=523.6\:in\:^3}}$
