Answer:
probability is 0.67
Step-by-step explanation:
We know that Angle in a circle = 360°
Area of total shaded parts = 60 + 60 = 120°
Area of total unshaded parts = 360-120 = 240°
Probability that a random selected point within the circle falls in the unshaded area
= 240/360
= 2/3= 0.67
Probability that a randomly selected point within the circle falls in the white area will be [tex]0.67[/tex] .
What is Probability ?Probability is the ratio of the number of outcomes to the total number of possible outcomes.
Probability [tex]=\frac{Number\ of\ possible\ outcomes}{Total\ number\ outcomes}[/tex]
We have,
Radius [tex]=4[/tex] cm
Now,
Area of Circle [tex]=\pi r^{2}[/tex]
Area of Circle[tex]=\frac{22}{7} *4^2=50.28\ cm^2[/tex]
Now,
Area of minor segment [tex]=\frac{\theta}{360^0} *\pi r^{2}[/tex]
Area of minor segment [tex]=\frac{60}{360} *\frac{22}{7}* 4^{2}=8.38\ cm^2[/tex]
Now,
We have two minor segment,
Area of two minor segment [tex]=8.38*2=16.76\ cm^2[/tex]
Now,
Area of white Portion [tex]=50.28-16.76=33.52\ cm^2[/tex]
Now,
Probability [tex]=\frac{Number\ of\ possible\ outcomes}{Total\ number\ outcomes}[/tex]
Probability [tex]=\frac{33.52}{50.28}=0.67[/tex]
So, the Probability of white area is [tex]0.67[/tex] .
Hence, we can say that Probability that a randomly selected point within the circle falls in the white area will be [tex]0.67[/tex] .

Answer:6
Step-by-step explanation:
write an explicit formula for an, the nth term of the sequence 11,2,-7
Answer:
[tex]a_{n}[/tex] = 20 - 9n
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 2 - 11 = - 7 - 2 = - 9
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 11 and d = - 9 , then
[tex]a_{n}[/tex] = 11 - 9(n - 1) = 11 - 9n + 9 = 20 - 9n

Answer:
x = 14
Step-by-step explanation:
4x - 4 + 4x - 4 + x = 118

Please help me out :)
Answer:
Q= (5,4)
Step-by-step explanation:
The x value went up by 4 units and the y value up by 6 units from the first point to the midpoint. Since the midpoint is equal distance from both points, we know it will go up by the same amounts for Q.
so 1+4= 5
-2+6= 4

the present price of a car is 33750 every year the price decreased by 4% find the price of a car after 4 years
Answer: 28,665 currency units
Step-by-step explanation:
Find the value of the car after 4 years using the Future value formula:
= Amount * ( 1 + rate) ^ no. of years
= 33,750 * ( 1 + (-4%))⁴
= 33,750 * 0.84934656
= 28,665.45
= 28,665 currency units

Answer:
1)54° 2)5π 3)a=3π 4)b 5)(x – 11)^2+ (y – 6)^2=36 6)center=(7,-6) radius=5 8)b
Step-by-step explanation:
1- π radians = 180°
so 3π/10=(3*180)/10=54°
2- in order to find arc length we need to find the ratio of the angles then make that equal to the ratio of the arc length to the perimeter:
x=arc length of HN
150/360=x/2πr
5/12=x/2*6π
5/12=x/12π
12*5π=12x
x=5π
3- in order to find the area of the shaded region we have to take the ratio of the angles and make that equal to the ratio of the area of the shaded region to the whole area:
a=area of the shaded region
30/360=a/πr^2
1/12=a/36π
36π=12a
a=3π
4- a slice of a 16 inch pizza has an area of 64π/8=8π
two slices of a 10 inch pizza has an area of 2*(25π/8)= 6.25π
therefore we would be more satisfied with a slice of an 16 inch pizza, which is b.
5- the formula for the equation of a circle is: (x – h)^2+ (y – k)2 = r2
h=x-coordinate of the center point k= y-coordinate of the center r=radius
in this question the center is (11,6) so h=11, k=6 and the radius is 6 so r=6
we plug in
(x – 11)^2+ (y – 6)^2=36
6- h=7 k=-6 so the center is (7,-6)
radius=5
8- center=(1,3) and radius=2
so the graph that corresponds to these values is b

In ABC with the right angle at vertex C, sin(b)= (26)/8. What is sin(a)?
Answer:
We can use the Pythagorean theorem and properties of sines, cosines, and tangents to solve the triangle, that is, to find unknown parts in terms of known parts.
Step-by-step explanation:
Pythagorean theorem: a2 + b2 = c2.
Sines: sin A = a/c, sin B = b/c.
Cosines: cos A = b/c, cos B = a/c.
Tangents: tan A = a/b, tan B = b/a.

Step-by-step explanation:
One is given the following information:
[tex]10\frac{1}{1}[/tex] km were covered on Thursday[tex]10\frac{1}{1}[/tex] km were covered on FridayOne is asked to find the total distance covered on both of these days. In order to do so, one must remember in a fraction, any number over (1) is equal to the numerator (number over the fraction bar). Thus one can form the following equation:
[tex](Thursday)+(Friday) = Total\ distance[/tex]
Substitute,
[tex](Thursday)+(Friday) = Total\ distance[/tex]
[tex](10\frac{1}{1})+(10\frac{1}{1}) = Total\ distance[/tex]
Simplify,
[tex](10\frac{1}{1})+(10\frac{1}{1}) = Total\ distance[/tex]
[tex](10+1)+(10+1) = Total\ distance[/tex]
[tex](11)+(11)=Total\ distance[/tex]
[tex]11+11=Total\ distance[/tex]
[tex]22=Total\ distance[/tex]

The size of a packet of pasta is increased by one-quarter.
The new size is later reduced by one-quarter.
is the new packet smaller, the same size or larger than the original?
Explain how you worked out your answer.
Answer: Smaller
Step-by-step explanation:
Multiplying a number by 1.25 increases it by a quarter
Multiplying a number by 0.75 decreases it by a quarter
1.25 / 0.75 = 0.9375
Thus, increasing something by a quarter then decreasing it by a quarter, you are effectively multiplying that number by 0.9375, which is less than 1, so the number will decrease.

Look at this graph: What is the equation of the axis of symmetry?
9514 1404 393
Answer:
x = -6
Step-by-step explanation:
The curve is symmetrical about the vertical line through the minimum point. That minimum is 6 grid squares left of the y-axis, so the equation is ...
x = -6
Solve for x
2 (x + 1) = -200 x= 66
2x + (-3) = = (-23) x=
X - 3 = (-9) x=
(-3x) - 5 = 16 x=
-4 (y - 2) = 12 x=
4x = (-28) x=
2x + 9 = (-15) x=
X + 5 = 18
3 (x+ 5) = 18
3x + 5 = 18
2 (x + 5) = 16
3 (y + 200) = 3000
20.8 = 4 (z + 1.1)
3 (x + 4.5) = 36
9 = 3 (x + 2)
2x + 16 = 50
14 = 2 (x + 3)
5x + 2 = 17
Answer:
---------
Step-by-step explanation:
x-3= -9
x= -9/ 3
x= -3
( -3x)-5 =16
-3x = 16+5
