A certain basketball player scores 60% of the free-throw shots she attempts. during a particular game, she gets six free throws. what is the probability that she scores on exactly four of the six shots? choose one.
The probability of scoring exactly four out of the given six shots is 0.311, calculated using the concept of binomial distribution in probability theory.
What is a Binomial Distribution?
Binomial Distribution in probability theory is defined as getting x number of successes on repetition of trial n times, the formula for binomial distribution is C(n,r) × (p)x × (q)n - r, where p denotes the probability of success and q denotes the probability of failure.
Calculation of the probability of scoring exactly four shots out of six
Let p denote the probability of success and q denote the probability of failure, which is equal to 1 - p.
Using Binomial Distribution, we get,
P(x = r) = C(n,x) × (p)x × (q)n - x
Taking r = 4,
P(x = 4) = C(6,4) × (0.6)4 × (0.4)2
= 6! / (4! 2!) × (0.6)4 × 0.16
= 0.31104
~ 0.311
Hence, the required probability using binomial distribution is 0.311.

find the vertex and write the quadratic function in vertex form (which our openstax textbook also calls the standard form).
The vertex is (3,16) and the quadratic equation in vertex form is [tex]f(x)=(x-3)^{2}+16\\[/tex].
What is quadratic equation?Any equation in algebra that can be put into standard form is called a quadratic equation (from the Latin quadratus, which means "square").
As well as being referred to as the roots or zeros of the expression on the left-hand side of the equation, the values of x that satisfy it are known as solutions of the equation. There are only two possible answers to a quadratic equation. A double root is said to exist if there is only one solution. In the case where all of the coefficients are real values, there are either two real solutions, one real double root, two complex solutions that are complex conjugates of one another, or all three of the aforementioned options. If complex roots are taken into account, then a quadratic equation will always have two roots, with a double root counting as one. An equivalent equation can be created from a quadratic equation.
Calculations:
[tex]f(x)=x^{2} -6x+25\\ = x^{2} -2.x.3+(3^{2} )-(3^{2} )+25\\=(x-3)^{2} -9+25\\=(x-3)^{2}+16\\[/tex]
Comparing this from the vertex, y=[tex]a[/tex][tex](h-x)^{2} +k\\[/tex]
h=3 and k=16
Hence, vertex is (3,16).

Distributive.Addition or subtraction property of equality.Addition or subtraction property of equality.multiplicationn or division property of equality.What is used in each step of the demonstration?We start by writing the linear equation:
3*(x + 2) = 4x + 1
The first step is using the distributive property to distribute the left product.
3x + 6 = 4x + 1
Then we use the addition property of equality to subtract 4x in both sides, we will get:
-x + 6 = 1
And we use it again to subtract 6 in both sides:
-x = 1 - 6 = -5
Finally, we multiply both sides by -1 (multiplication property of the equality)
x = 5
That is the solution of the linear equation.

The navy and aviation industries use it. It's applied to cartography (creation of maps). Trigonometry is also used in satellite navigation systems.Given: height of helicopter = 300√3 feet from the ground.
To find: Distance between zoo and library.
Finding:
(Refer to the image attached.)
Let the distance from the plane to the zoo and library be d1 and d2 respectively.
Then, with the help of concepts of applications of trigonometry,
For the zoo:[tex]tan(60) = \frac{300\sqrt{3}}{d1}[/tex]
=> [tex]\sqrt{3}=\frac{300\sqrt{3}}{d1}[/tex]
=> d1 = 300 feet
For the library:[tex]tan(30) = \frac{300\sqrt{3}}{d2}[/tex]
=> [tex]\frac{1}{\sqrt{3}}=\frac{300\sqrt{3}}{d2}[/tex]
=> d2 = 300 (3) = 900 feet
The distance between zoo and library = d2 - d1 = 900 - 300 = 600 feet.

Solve inequality.
9 a<45
To solve the inequality, divide both sides by 9. The solution is a < 5 or (∞, 5)
Tips to solve linear inequalities:
Isolate the variable on one side by using subtraction or addition. Subtraction and addition will not change the inequality.Use division or multiplication to find the solution. Multiplication and division by a positive number will not the inequality. However, if we multiply or divide both sides with a negative number, we need to flip the inequality direction.Interval notation is often used for the solution(s). Recall the differences between a bracket [ or ], and a parenthesis ( or ). A bracket means the endpoint is included in the solution while a parenthesis means the endpoint is not included in the solution. Remember, infinity ∞ always use a parenthesis.
Example: x ≥ 2 can be written as [2, ∞), while
x > 0 is written as (2, ∞)
The given problem:
9a < 45
Notice that the variable, a, is already isolated on the left side. Divide both sides by 9: (Note that the inequality sign is not flipped since 9 is a positive number)
9a : 9 < 45 : 9
a < 5
Using the interval notation, the solution is (∞, 5)

The length of the enclosure for the pancake tortoise must be greater than the height. The volume of the enclosure is expressed in terms of the width, w.
w^3+6w^2-40w
Factor the expression, then match the factors to the dimensions they represent.
The factors of the expression w³ + 6w² - 40w = 0 is (w - 4) and (w + 10)
(w - 4) will be the height
(w + 10) will be the length
Given,
The length of the enclosure for the pancake tortoise will be greater than the height, that is: l > h
The volume of enclosure = w³ + 6w² - 40w
Where w is the width.
Now, factorize the expression:
w³ + 6w² - 40w = 0
10 - 4 = 6
10 × (-4) = -40
Therefore, the factors of the expression w³ + 6w² - 40w = 0 is (w - 4) and (w + 10)
Here, we know that length is greater than height.
So, (w - 4) will be the height and (w + 10) will be the length.

We are to find approximately how many pink flowers are predicted to bloom on a shrub with 40 red flowers. The equation given is: y = 1.73x + 0.0924 and we see that red flowers are on the x-axis and pink flowers are on the y-axis.
Since we know there are 40 red flowers and red flowers are on the x-axis, x = 40. Plug into the equation:
y = 1.73x + 0.0924 where x = 40
y = 1.73(40) + 0.0924
y = 69.2 + 0.0924

so, we have a kite here.
a kite is a quadrilateral, that is totally symmetric along one of its diagonals.
the sum of all internal angles of a quadrilateral is always 360°.
remember, the sum of all angles around one point on one side of a line is always 180°.
a full circle airways represents 360°.
the inner angle at 140° is
180 - 140 = 40°
the inner angle at 250° is
360 - 250 = 110°
the inner angles at x and its opposing corner are equal (due to the symmetry) and are in sum with the other 2 inner angles 360°.
so, we have for the inner angles
360 = 110 + 40 + 2×xinner
210 = 2×xinner
the inner angle of x = 105°.
x (the outer angle of the inner angle of x) is
x = 360 - 105 = 255°

what was the approximate average speed, in meters per second, of the ocean current that carried the ducks to shore? (rubber ducks from the same spill began to appear on the coast of maine in july 2003.) use an average month length of 30 days.
There is an approximate average velocity. 0.1 m/s, or 0.222 m/h.
What is average velocity?A vector quantity is average velocity. The change in position and otherwise displacement (x) divided by that of the time intervals (t) during which the displacement happens is the definition of average velocity. The average velocity may be either positive or negative depending on the displacement's direction.
According to the given information is:The distance covered by the rubber ducks = 1600 miles.
The duration needed to cover this distance = 10 months.
The average ocean speed, according to definition, is
v = (1600 miles)/(10 months)
Now,
1 mile = 1609 m
10 months = (10 months)*(30 days/month) *(24 hours/day)
= 7200 hours (approx.)
= 7200*3600
= 2.592 x 10⁷ s
So that,
ν = [tex]\frac{(1600 \mathrm{~m}) *\left(1609 \frac{\mathrm{m}}{\mathrm{mi}}\right)}{(10 \mathrm{months}) *\left(2.592 \times 10^7 \frac{\mathrm{g}}{10 \mathrm{mon} t h}\right)}[/tex]
= 0.0993 m/s
Also,
ν = 1600/7200
= 0.222 mi/h
