Keisha is playing a game using a wheel divided into eight equal sectors, as shown in the diagram. Each time the spinner lands on white, she will win a prize. If she spins this wheel twice, what is the probability she will win a prize on both spins? Please show all steps!
Answers
Answer:
[tex] \frac{4}{64} [/tex]
Step-by-step explanation:
The spinner is independent (the total won't be effected)
we know there is 2 whites with 8 coloured option.
[tex] \frac{2}{8} [/tex]
we want the probability of getting two whites.
[tex] \frac{2}{8} \times \frac{2}{8} = \frac{4}{64} [/tex]
there is 3 ways to work out probability, fraction, decimal and percentage (i'd personally say fraction is the most easiest)
The probability of Keisha to win a prize on both spins in a game of wheel which is divided in eight equal sectors is 1/16.
What is probability?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
Keisha is playing a game using a wheel divided into eight equal sectors, as shown in the diagram.
Each time the spinner lands on white, she will win a prize. If she spins this wheel twice,
Here, the white is appeared twice in the wheel and the total number of sector in wheel are 8. Thus the probability of first time to come white in the spin is,
[tex]P=\dfrac{2}{8}\\P=\dfrac{1}{4}[/tex]
The conditions are same for the second case. For this case, both result of both the spins of wheel are independent of each other.
Thus, by the chain rule, the probability both spin as white sector appear is,
[tex]P=\dfrac{1}{4}\times\dfrac{1}{4}\\P=\dfrac{1}{16}[/tex]
Thus, the probability of Keisha to win a prize on both spins in a game of wheel which is divided in eight equal sectors is 1/16.

Answers
Answer:
{Monday, Tuesday, Wednesday, Thursday}
Step-by-step explanation:
First we need to get the complement of B i.e B'
B' are the set in the Universal set but that are not in B
B' = {Monday, Tuesday, Wednesday, Thursday}
A= {Monday, Tuesday, Wednesday, Thursday, Friday}
A intersect B ' are the days of the week that are common to both sets;
A intersect B ' = {Monday, Tuesday, Wednesday, Thursday}

Solve for x
2^x= 0.0625(X is an integer)
Answers
Answer:
there you go:)
..................
This question is to do with logs and indices
2^x =0.0625
we know that 2³=8
And log2(8) = 3
*using this form we can solve for x*
2³=8
2^x =0.0625
log?(?) = ?
Both indices have a base of 2 so the log2 stays the same
Instead of 8 we put the 0.0625 in the bracket
So we get
log2(0.0625) = ?
Put this in your calculator and you should get
log2(0.0625) = -4

So, Christian has a collection of 18 shark teeth. He identified them as 6 tiger shark teeth, 8 sand shark teeth, and the rest as bull shark teeth, I don’t get the 2nd question, can anyone help??
Answers
Answer:
So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth. And, the number of bull shark teeth is 4.
Step-by-step explanation:
So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth.
Since Christian has 18 shark teeth, and 6 are tiger shark teeth, 8 are sand shark teeth and the rest are bull shark teeth.
Let x represent the number of bull shark teeth.
So, total number of shark teeth = number of tiger shark teeth + number of sand shark teeth + number of bull shark teeth.
18 = 6 + 8 + x
18 = 14 + x
subtracting 14 from both sides, we have
18 - 14 = 14 - 14 + x
4 = 0 + x
4 = x
x = 4
So, the number of bull shark teeth is 4.

Answers
Answer:
Median is 18
Step-by-step explanation:
Firstly you have to fine y by using your mean
Therefore, 22+18+(2y+1)+10+20 divide it by the number of the mean that is the sum of the number divide by the total number of the mean which is 5 =15
22+18+2y+1+10+20 over 5 =15
71+y over 5 =15
Cross multiple
71+y=75
y=4
22,18,9,10, 20
Rearrange
9,10,18,20,22
The median is 18

The image of the polygon after a reflection in the line y=x is has vertices at A'(-3, 6), B'(-2, 1) and C'(1, 4) as shown in the diagram attached.
Transformation is the movement of a point from the initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.
Reflection is the flipping of a figure. If a point A(x, y) is reflected about the line y = x, the new point would be at A'(y, x)
Given the polygon with vertices at A(6, -3), B(1, -2) and C(4, 1). The image of the polygon after a reflection in the line y=x has vertices at:

Find the perimeter of the figure to the nearest hundredth.
Answers
Answer:
42.84cm
Step-by-step explanation:
The perimeter is the sum of all the side length and the circumference of the semicircle
circumference of the semicircle = 2πr/2 = πr
circumference of the semicircle = 3.14 * (12/2)
circumference of the semicircle = 3.14 * 6
circumference of the semicircle = 18.84cm
Perimeter of the figure = 10cm + 6cm + 8cm + 18.84cm
Perimeter of the figure = 42.84cm (to nearest hundredth)
