This question is incomplete, the complete question is;
A basketball player has a 60% accuracy rate for making free throws. During practice, this player fails to make a free throw three times in a row, but is finally successful on the fourth attempt.
p(x=k) = p^k (1-p)^k-1
Using the geometric distribution formula, what is the probability of this player successfully making a free throw on the fourth attempt? Each attempt is independent of each other and answer choices are rounded to the hundredths place.
a.) 0.04
b.) 0.60
c.) 0.40
d.) 0.10
Answer: a.) 0.04
Step-by-step explanation:
Given that;
The basketball player has 60% accuracy of free throws
Now the probability of the player successfully making a free throw on the fourth attempt.
probability of success p = 0.60
number of failure k = 3
the given p.d.f of geometric distribution p(x=k) = p^k (1-p)^k-1
{ 0 <p<= 1 , k=0,1,2,3... }
we substitute our given data
p(x=3) = 0.60^3 (1-0.6)^3-1
= (0.60)^3 (0.40)^2
= 0.216 * 0.16
= 0.035 = 0.04 ( OPTION A)

Use the map shown below to find the distance between cities A and B to the nearest tenth.
Answer:
7.2 units
Step-by-step explanation:
Coordinates of city A = (0, 0)
Coordinates of city B = (6, 4)
Use the distance formula to find the distance between the two cities as follows:
[tex] AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] A(0, 0) = (x_1, y_1) [/tex]
[tex] B(6, 4) = (x_2, y_2) [/tex]
Plug in the values into the formula
[tex] AB = \sqrt{(6 - 0)^2 + (4 - 0)^2} [/tex]
[tex] AB = \sqrt{(6)^2 + (4)^2} [/tex]
[tex] AB = \sqrt{36 + 16} = \sqrt{52} [/tex]
[tex] AB = 7.2 [/tex] (nearest tenth)

A 34 inch baseball bat is resting 6 inches from the base of a play house as shown how far up on the Playhouse is a baseball bat resting round to the nearest 10th
the sum of 3 numbers is 114. the second number is 4 times the third the third number is 6 more than the first
Answer:
let the three numbers be x,y,z
X= z-6
Y= 4z
Z= z
Step-by-step explanation:
X+Y+Z=114
hence
=z-6+4z+z=114
=collect like times. X= 20-6=14
= z+4z+z=114+6. Y= 20*4=80
=6z=120. . Z= 20
z=20
Answer:
14 + 20 + 80 = 114
Step-by-step explanation:
Let's begin by representing our 1st number as x.
Then our 2nd number is said to be 6 more than the 1st number, which we can represent as x + 6.
Lastly, our 3rd number is said to be 4 times the 2nd number, which we can represent as 4(x + 6).
Now can write our equation to express the sum of these three numbers as 114 and then solve for x to find the values of these three numbers:
x + (x + 6) + 4(x + 6) = 114
x + x + 6 + 4x + 24 = 114
6x + 30 = 114
6x = 114 - 30
6x = 84
x = 84/6 = 14 (1st number)
x + 6 = 14 + 6 = 20 (2nd number)
4(x + 6) = 4(20) = 80 (3rd number)
We can check our answers by adding these numbers up to see if their sum is 114:
14 + 20 + 80 = 114
34 + 80 = 114
114 = 114
Their sum is 114, so we are confident that our three numbers are correct.

A gardener fills a 2 1/2 cubic foot wheelbarrow 2/3 of the way without soil weight 75.25 pounds. What is the weight of the soil un wheelbarrow?
Volume of wheelbarrow , V = 2 1/2 ft³ = 5/2 ft³.
Volume of soil in wheelbarrow , [tex]v = \dfrac{5}{3}\ ft^3[/tex] .
Mass of soil in wheelbarrow , m = 75.25 pounds.
Now, volume left , [tex]v'=\dfrac{5}{6}\ ft^3[/tex] .
Let, mass of soil un wheelbarrow is x.
[tex]x=\dfrac{\dfrac{5}{6}\times 75.25}{\dfrac{5}{3}}\\\\x=37.625\ pounds[/tex]
Hence, this is the required solution.

16. Find the values of x and y. (2y + 5) (5x - 17) (3x – 11)º
Answer:
x = 26
y = 9
Step-by-step explanation:
(5x - 17)° + (3x - 11)° = 180° (angles in a straight line)
Solve for x
5x - 17 + 3x - 11 = 180
Collect like terms
5x + 3x - 17 - 11 = 180
8x - 28 = 180
Add 28 to both sides
8x = 180 + 28
8x = 208
Divide both sides by 8
x = 208/8
x = 26
Also:
(2y + 5)° + 90° + (3x - 11)° = 180° (angles on a straight line)
Plug in the value of x and solve for y
2y + 5 + 90 + 3(26) - 11 = 180
2y + 5 + 90 + 78 - 11 = 180
Collect like terms
2y + 162 = 180
Subtract 162 from both sides
2y = 180 - 162
2y = 18
y = 9 (dividing both sides by 2)

y/-5=1/10
Enter your answer as a reduced fraction.
Answer:
1/2
Step-by-step explanation:
y/-5=1/10
multiply -5 on both sides
y/-5 x -5 - cancels
1/10 x -5/1
1/10 x -50/10 = 5/10 = 1/2
so then its y=1/2
The maximum speed that an X43A plane can reach is 7,500 miles per hour. At this speed, how many feet
can the X43A travel in 1 second? (1 mile = 5,280 feet)
Answer:
11000 feet/secondsStep-by-step explanation:
This problem requires that we convert from miles per hour to feet per seconds
Given that the speed of the X43A plane is 7500 mph
and that 1 mile = 5,280 feet)
[tex]=\frac{7500miles}{h} *\frac{5280 feet}{mile} \frac{1hour}{3600 seconds} \\\\=\frac{7500*5280}{3600} \\\\=\frac{396*10^5}{3600} \\\\=11000 feet/seconds\\\\=11*10^3feet/seconds\\\\[/tex]
Therefore the speed of the X43A plane in feet per second is 11000

A line has a slope of 2 and passes through the point ( -1, 3). Write an equation in slope intercept form
Answer:
y=2x+5
Step-by-step explanation:
The equation of a line in slope intercept form is written as: y=mx +b where m is the slope and b is the y-intercept.
Taking point (-1,3) , m= 2 and imaginary point on the line, (x,y) then ;
m=change is y-coordinates/change in x-coordinate
m=Δy/Δx
m=y-3/x--1
2= y-3 / x+1
2(x+1) = y-3
2x +2 =y-3
2x=y-3-2
2x=y-5
y=2x+5 is the equation.

Determine whether the given segments have the same length. Drag and drop each number
into the correct box to complete the justification of your answer. BC and EF
Answer:
Step-by-step explanation:
Length of a segment between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Coordinates of extreme ends of BC and EF are,
B(1, 4), C(3, -2), E(-3, -2) and F(-1, 1)
Length of BC = [tex]\sqrt{(1-3)^2+(4+2)^2}[/tex]
= [tex]\sqrt{4+36}[/tex]
= [tex]2\sqrt{10}[/tex] ≈ 6.32 units
Length of EF = [tex]\sqrt{(-3+1)^2+(-2-1)^2}[/tex]
= [tex]\sqrt{4+9}[/tex]
= [tex]\sqrt{13}[/tex] ≈ 3.61 units
The length of BC is 6.32. The length of EF is 3.61.So, BC and EF don't have the same length.
