Answer:
0.0009 probability of obtaining exactly 1 head
Step-by-step explanation:
For each toss, there are only two possible outcomes. Either it is a head, or it is not. The probability of a toss being a head is independent of any other toss. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
A fair coin is tossed 14 times.
Fair coin means that it is equally as likely to be heads or tails, so [tex]p = 0.5[/tex]
14 times means that [tex]n = 14[/tex]
What is the probability of obtaining exactly 1 head?
This is P(X = 1).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 1) = C_{14,1}.(0.5)^{1}.(0.5)^{13} = 0.0009[/tex]

If a wheel of a bicycle covers 440m in 200 rotation. find the area of a wheel.
Answer:
7/22
Step-by-step explanation:
Area = 400/200 × 400/200 ×1/4 × 7/22 = 7/22
Step-by-step explanation:
Total distance covered in 200 rotation = 440 m
Distance covered in 1 rotation
= 440 / 200
= 2.2 m
Distance covered in 1 rotation = Circumference of circle so
circumference = 2πr
2.2 = 2 * 22/7 * r
2.2 = 6.28 r
r = 2.2 / 6.28
r = 0.35 m
Now Area of the wheel
= πr²
= 22 /7 * 0.35 * 0.35
= 0.385 m²
Hope it will help :)❤

Answer:
about 236.715 ft²
Step-by-step explanation:
area of a circle = πr²
so π7.5² = 176.7145868
area of a rectangle is b × h
so 15 × 4 = 60
60 + 176.7145868 = 236.7145868 ft² ≈ 236.715 ft² (for the nearest thousandths)

A. 98pi units3
B. 784pi units3
C. 112pi units3
D. 196pi units3
Answer:
D) 196π
Step-by-step explanation:
Volume of a cylinder formula:
V = πr²h
Given:
r = 7
h = 4
Work:
V = πr²h
V = π7²(4)
V = 49(4)π
V = 196π
Find the area of the triangle. If necessary, round the answer to two decimal places.
a = 12, b = 15, C = 52°
A)35.46
B)70.92
C)88.80
D)141.84
Answer:
B) 70.92
Step-by-step explanation:
a = 12
b = 15
C = 52°
[tex] area = \dfrac{ab \sin C}{2} [/tex]
[tex]area = \dfrac{12(15) \sin 52^\circ}{2}[/tex]
[tex] area = 70.92 [/tex]
Answer:
c
Step-by-step explanation:
because 15 x 12 is 180 so multiply by .5 and you get 90 and 88.80 is the closest thing to 90
Write an equation of the line that passes through point P and is parallel to the line with the given equation: P(2,5) Y-1=4x
Given:
The equation of a line is:
[tex]y-1=4x[/tex]
A line parallel to the above line passes through the point P(2,5).
To find:
The equation of the parallel line.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope and b is the y-intercept.
The given equation is:
[tex]y-1=4x[/tex]
It can be rewritten as
[tex]y=4x+1[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=4[/tex]
It means the slope of the given line is 4.
We know that the slopes of two perpendicular lines are equal. So, the slope of the required parallel line is also 4.
The parallel line passes through the point P(2,5) with slope 4, thus the equation of the parallel line is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-5=4(x-2)[/tex]
[tex]y-5=4x-8[/tex]
[tex]y=4x-8+5[/tex]
[tex]y=4x-3[/tex]
Therefore, the equation of the required parallel line is [tex]y=4x-3[/tex].

Leon makes a rectangular logo for his skateboarding club. He cuts from fabric two copies of the trapizoid shown and joins them to form a rectangle. What is the area of the rectangular logo leon makes
Answer:
Area of the rectangular logo is 56cm²
Step-by-step explanation:
If we look at the picture the 2 trapezoids make a rectangle.
The length of the rectangle = 9+5= 14 cm and the breadth = 4 cm
Area of the rectangle = Length * breadth
A= 14*4= 56cm²
Area of the rectangular logo is 56cm²
Area of the trapezoid = 28 cm²
Area of the trapezoid = 1/2height( base1+ base2)
= 1/2 (4) ( 5+9)
= 2(14)= 28 cm²
Area of 2 trapezoids = 28 cm²+28 cm²= 56 cm²

[tex]ratio = \frac{600}{275} \\ = \frac{120}{55} \\ = \frac{24}{11} [/tex]
The function g(x) is a translation of f(x) = (x + 3)2 – 10. The axis of symmetry of g(x) is 5 units to the right of f(x) . Which function could be g(x)?
g(x) = (x – 2)2 + k
g(x) = (x + 8)2 + k
g(x) = (x – h)2 – 5
g(x) = (x – h)2 – 15
Answer:
a.
g(x) = (x – 2)2 + k
Step-by-step explanation:
The function that could be g(x) is (a) g(x) = (x - 2)^2 + k
How to determine the function?The function f(x) is given as:
f(x) = (x + 3)^2 - 10
The axis of symmetry of g(x) is 5 units to the right of f(x).
This means that:
g(x) = f(x - 5)
So, we have:
f(x - 5) = (x - 5+ 3)^2 + k
Evaluate the difference
f(x - 5) = (x - 2)^2 + k
Substitute g(x) = f(x - 5)
g(x) = (x - 2)^2 + k
Hence, the function that could be g(x) is (a) g(x) = (x - 2)^2 + k

Given that the four points A(1,2), B(2, -5), C(7,0) and D(p,q) are the vertices of the rhombus ABCD
calculate
a) the value of p and of q
Step-by-step explanation:
Three coordinates of a Rhombus is given to us. And the fourth coordinate is D(p,q) . Weneedtofind the value of p and q . We know that the diagonals of Rhombus bisect each other at right angles . So lets find the midpoint.
• Midpoint of AC :-
[tex]\tt\to Midpoint_{(AC)}= \bigg(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\bigg)\\\\\tt\to Midpoint_{(AC)}= \bigg( \dfrac{1+7}{2},\dfrac{2+0}{2}\bigg)\\\\\tt\to Midpoint_{(AC)}= \bigg(\dfrac{8}{2},\dfrac{2}{2}\bigg)\\\\\tt\to \boxed{\orange{\tt Midpoint_{(AC)}= (4,1)}}[/tex]

• Midpoint of BD :-
[tex]\tt\to Midpoint_{(BD)}= \bigg(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\bigg)\\\\\tt\to \boxed{\orange{\tt Midpoint_{(BD)}= \bigg( \dfrac{2+p}{2},\dfrac{q-5}{2}\bigg)}}[/tex]
_______________________________
Now since these two coordinates must be equal, therefore ,
