The probability that marksman will hits the target at most 13 times is  27.92%.

The number of successes ("x") is the probability mass function for such binomial distribution.

P(X = x) = ⁿCₓ . pˣ . qⁿ⁻ˣ

We are interested in the likelihood that the target will be struck exactly five times, therefore the desired number of successes is five (i.e., x = 13).

P(X = 13) =  ¹⁵C₁₃. (0.89)¹³ (0.11)²

P(X = 13) = 0.2792

P(X = 13) = 27.92%

Thus, the probability that marksman will hits the target at most 13 times is  27.92%.

Answer:The answer is below

Step-by-step explanation:

The bottom of a river makes a V-shape that can be modeled with the absolute value function, d(h) = ⅕ ⎜h − 240⎟ − 48, where d is the depth of the river bottom (in feet) and h is the horizontal distance to the left-hand shore (in feet). A ship risks running aground if the bottom of its keel (its lowest point under the water) reaches down to the river bottom. Suppose you are the harbormaster and you want to place buoys where the river bottom is 20 feet below the surface. Complete the absolute value equation to find the horizontal distance from the left shore at which the buoys should be placed

Answer:

To solve the problem, the depth of the water would be equated to the position of the river bottom.

Answer:

1.4 meters

Step-by-step explanation:

Given,

Volume of rectangular prism ( V ) = 18.144 cubic meters

Width ( w ) = 2.7 m

Length ( l ) = 4.8 m

To find : d

Here, d is Height ( h ).

Formula : -

V = whl

18.144 = 2.7 x 4.8 x d

18.144 = 12.96 x d

d = 18.144 / 12.96

d = 1.4 meters

\( \huge\fbox\green{ANSWER} \)

\(v = l \times w \times h\)

\(18.144 {m}^{3} = 4.8m \times 2.7m \times d\)

\(18.144 {m}^{3} = 12.96 \times d\)

\( \frac{18.144 {m}^{3} }{12.96 {m}^{2} } = \frac{12.96 {m}^{2} }{12.96 {m}^{2} } \times d\)

\(1.4m = d\)

We know that 1 litre = 1.05669 Quarts using the conversion factors.

If you want to change the units of a measured quantity without changing the value, you can do so by using a conversion factor, which is an expression representing the relationship between the units.

A conversion ratio (or unit factor), if the numerator and denominator have the same value represented in various units, always equals one (1).

One unit of measurement can be converted into another using conversion factors.

The conversion procedure entails changing a company's single-entry accounting system to a double-entry one.

While we were learning about conversion factors, we know that:

1 litre = 1.05669 Quarts

Therefore, we know that 1 litre = 1.05669 Quarts using the conversion factors.

The object will be 78.4 meters high after 2 seconds of launch.

We will put t = 2 in the equation to find the height.

s(2) = -4.9(2)² + 19.6(2) + 58.8s(2) = -4.9(4) + 39.2 + 58.8s(2) = -19.6 + 98s(2) = 78.4

Therefore, the object will be 78.4 meters high after 2 seconds of launch.

The formula to calculate the height of an object s(t) at time t seconds after launch is:s(t) = -4.9t² + 19.6t + 58.8where s is in meters.

Using this formula, we can find the height of the object after 2 seconds.

s(2) = -4.9(2)² + 19.6(2) + 58.8s(2) = -4.9(4) + 39.2 + 58.8s(2) = -19.6 + 98s(2) = 78.4

Expressing this function as a piecewise function, we get;

y = -x + 1         for x< -5

y = -1/2x + 4    for x> 4

According to the question, we can see that the graph is a line for x < -5. We will find two points on this line to find out the slope.

( - 5,6) and ( -8,9)

The slope is m= ( y2-y1)/(x2-x1)

m = ( 9-6)/(-8 - -5) = 3/ ( -8+5) = 3/-3

The slope is -1

Using point-slope form, we will find the general equation of this line

y-y1 = m(x-x1)  and the point ( -8,9)

y -9 = -1(x - -8)

y -9 = -1(x +8)

y-9 =  -x - 8

y = -x + 1   for x< -5

The graph is a line for  x > 4

(4,2) and ( 6,1)

The slope is m= ( y2-y1)/(x2-x1)

m = ( 1 - 2)/(6 - 4) = -1/ (2) = -1/2

The slope is -1/2

Using point-slope form

y-y1 = m(x-x1)  and the point (6,1)

y -1 = -1/2(x - 6)

y-1 = -1/2 x  + 3

y = -1/2x + 4   for x> 4

Area of composite figure = 623.25 cm²

Step-by-step explanation:

Given:

Equal side of triangle = 39 cm

Diameter of semi-circle = 30 cm

Base of triangle = 30 cm

Find;

Area of composite figure

Computation:

Radius of triangle = 30 / 2

Radius of triangle = 15 cm

Height of triangle = √39² - 15²

Height of triangle = √1,521 - 225

Height of triangle = 36 cm

Area of composite figure = Area of semi-circle + Area of triangle

Area of composite figure = [πr² / 2] + [(1/2)(b)(h)]

Area of composite figure = [(3.14)(15)² / 2] + [(1/2)(15)(36)]

Area of composite figure = [(3.14)(225) / 2] + [(15)(18)]

Area of composite figure = [706.5 / 2] + [270]

Area of composite figure = 353.25 + 270

Area of composite figure = 623.25 cm²

Answer:

45 million

Step-by-step explanation:

There will be approximately 45 million streams on the seventh day after the song's release.

To solve the problem, use the formula for exponential growth:

\(N(t) = N0 * (1 + r)^t\)

where

N(t) is the number of streams at time t,

N0 is the initial number of streams,

r is the daily growth rate expressed as a decimal, and

t is the time elapsed in days.

In this case, N0 = 15 million, r = 0.2 (since the number of streams increases by 20% per day), and t = 7 (since we want to know the number of streams on the seventh day).

Plugin these values into the formula

\(N(7) = 15 * (1 + 0.2)^7\\N(7) = 15 * 1.2^7\)

N(7) = 15 * 2.985984

N(7) = 44.78976

N(7) ≈ 45 million

Therefore, there will be approximately 45 million streams on the seventh day after the song's release.

The probability of randomly drawing 10 cards from a deck and getting exactly 5 spades is 0.0468

Formula Required:

Given a set of n items, a group of k items can be chosen in any of the 'n' ways, where 'k' is the number of possibilities. The order in which the choices are made is not significant.

A typical deck of cards contains 52 cards in total. Therefore, there exist (52, 10) scenarios in which 10 cards could be chosen (without replacement) that are exhaustive, mutually exclusive, and equally likely.

Again, there are 13 spades in the entire deck of 52 cards. The remaining (10 - 5) = 5 cards can be drawn from the remaining (52 - 13) = 39 cards in the deck in (39, 5) ways, and 5 spades can be drawn from the 13 spades in (13, 5) ways.

As a result, there are (13, 5) * advantageous scenarios for choosing exactly 5 spades (39, 5)

Consequently, the necessary probability:

= Favorable number of cases for the event / Total number of all possible cases.

= (13 , 5) * (39 , 5) / (52 , 10)

(n, k) = n! / k! (n-k)!  

= 0.0468

Therefore, the probability of 5 spades will be 0.0468

Answer:

If 20 more soldiers join it would last 48 days

Step-by-step explanation:

if 80 soldiers need 84000 food for 60 days it means that in 60 days one soldier eats 84000/80= 1050 each

then 1050/60=17.5 meaning they need 17.5 food a day each,

adding 20 soldiers means 80+20= 100 soldiers

100*17.5=1750 food is eaten every day

84000/1750= 48 which means that 100 soldiers will eat 84000 in 48 days

A Southern Pacific rattlesnake is more likely to be longer than 43.6 inches.

To calculate the probability of a rattlesnake having a length greater than 43.6 inches, we need to find the standard score (z-score) of 43.6 inches for each species and then use a standard normal table to find the corresponding probability.

The formula for the standard score is:

\($z = \frac{x - \mu}{\sigma}$\) where,

For Great Basin rattlesnakes:

\($\mu\) = 40 inches

\($\sigma\) = 7.2 inches

So,

\($z = \frac{43.6 - 40}{7.2} = 0.5$\)

Using a standard normal table, we find that the probability of a Great Basin rattlesnake having a length greater than 43.6 inches is approximately 0.306.

For Southern Pacific rattlesnakes:

\($\mu\) = 40 inches

\($\sigma\) = 10.8 inches

So,

\($z = \frac{43.6 - 40}{10.8} = 0.333$\)

Using a standard normal table, we find that the probability of a Southern Pacific rattlesnake having a length greater than 43.6 inches is approximately 0.379.

So,  a Southern Pacific rattlesnake is more likely to be longer than 43.6 inches.
