Answer: 0.001389
Step-by-step explanation:
Since you have 6 probabilities that it could be red, you get 1/6. Now, you took 1 probability out of 6, so now you only have 5. So you multiply 1/6 by 1/5. Now you have only 4 cards. Multiply 1/ 6 * 1/5 * 1/4 and keep going (e.g 1/6 * 1/5 * 1/4 * 1/3 * 1/2 * 1). This comes out to 0.00138888888, or rounded to six decimal places, 0.001389.

Samples of rejuvenated mitochondria are mutated (defective) in 1% of cases. Suppose 18 samples are studied, and they can be considered to be independent for mutation. Determine the following probabilities.(a) No samples are mutated.(b) At most one sample is mutated.(c) More than half the samples are mutated.Round your answers to two decimal places (e.g. 98.76).
Answers
Probability that no samples are mutated is 0.83, probability that at most one sample is mutated is 0.9812 and probability that more than half the samples are mutated is 0.
Given percentage of rejuvenated mitochondria defective is 1%, and sample size is 18.
Binomial distribution is the probability of exactly x successes on n repeated trials and X can have two outcomes.
P(X=x)=[tex]C_{n,x} p^{x}(1-p)^{n-x}[/tex]
percentage of defective rejuvendated mitochondria=1%
p=0.01
Sample size=18
n=18
a) No samples are mutated
This means P(X=0)=[tex]C_{18,0}(0.01)^{0} (0.99)^{18}[/tex]
=0.83
b) At most one sample is mutated.
P(X<=1)=P(X=0)+P(X=1)
so,
P(X=0)=[tex]C_{18,0} (0.01)^{0} (0.99)^{18}[/tex]
=0.83
P(X=1)=[tex]C_{18,1}(0.01)^{1} (0.99)^{17}[/tex]=
=0.1512
P(X<=1)=0.83+0.1512
=0.9812
c) More than half the samples are mutated.
P(X>9)=P(X=10)+P(X=11)+P(X=12)+P(X=13)+P(X=14)+P(X=15)+P(X=16)+P(X=17)+P(X=18)
Using two decimals digits precision all will be 0.
Hence Probability that no samples are mutated is 0.83, probability that at most one sample is mutated is 0.9812 and probability that more than half the samples are mutated is 0.

In the air, it had an average speed of 16 \text{m/s}m/start text, m, slash, s, end text. In the water, it had an average speed of 33 \text{m/s}m/start text, m, slash, s, end text before hitting the seabed. The total distance from the top of the cliff to the seabed is 127 meters, and the stone's entire fall took 12 seconds.
How long did the stone fall in the air and how long did it fall in the water?
Answers
The time taken by the stone to fall in air is 7 seconds and the time taken in water is 5 seconds.
What is Speed?Speed is the distance covered by an object in a fixed period of time. It is measured in m/sec.
The average speed in air is 16m/sec.
The average speed in water is 33m/sec.
The total time taken is 12 seconds.
Total distance covered = Total time taken * speed at which it covered the distance
Let the time taken to fall in air is t
So, the time taken in water will be 12-t
The total distance is equal to
127 = 16*t + 3(12-t)
127 = 16t + 36 - 3t
127 - 36 = 16t - 3t
91 = 13t
t = 91/13 = 7 seconds
12-t = 12-7 =5 seconds
Therefore, the time taken by the stone to fall in air is 7 seconds and the time taken in water is 5 seconds.

On a statistic exam, a class of 25 students had a mean score 75.2 and a standard deviation of 5.7. using the empirical rule, what would be the range of scores for 95% of the class?
Answers
The range of scores for 95% of the class is 63.8 to 86.6 using the empirical rule.
What is the empirical rule?A statistical principle known as the empirical rule, also known as the three-sigma rule or 68-95-99.7 rule, holds that with a normal distribution, almost all observed data will lie within three standard deviations.
The empirical rule specifically states that 68 percent of data will fall inside the first standard deviation, 95 percent will fall within the first two standard deviations, and 99.7 percent will fall within the first three standard deviations.
According to the question,
μ=75.2 and σ=5.7
So, according to the empirical rule, the range of scores for 95% of the class:
μ – 2σ =75.2-2*5.7=63.8
and μ + 2σ=75.2+2*5.7=86.6

The table shows ordered pairs of the function y = 16 + 0.5x .
A 2-column table with 6 rows. The first column is labeled x with entries negative 4, negative 2, 0
Answers
The missing values represented by x and y are 8 and 20, that is
(x, y) = (8, 20)
The function y = 16 + 0.5x is a linear equation that can be solved graphically. This means the values of both variables x and y can be found on different points along the straight-line graph.
The ordered pairs simply mean for every value of x, there is a corresponding value of y.
The 2-column table has values for x and y which all satisfy the equation y = 16 + 0.5x. Taking the first row, for example, the pair is given as (-4, 14).
This means when x equals negative 4, y equals 14.
Where y = 16 + 0.5x
y = 16 + 0.5(-4)
y = 16 + (-2)
y = 16 - 2
y = 14
Therefore the first pair, just like the other four pairs all satisfy the equation.
Hence, looking at the options given, we can determine which satisfies the equation
(option 1) When x = 0
y = 16 + 0.5(0)
y = 16 + 0
y = 16
(0, 16)
(option 2) When x = 5
y = 16 + 0.5(5)
y = 16 + 2.5
y = 18.5
(5, 18.5)
(option 3) When x = 8
y = 16 + 0.5(8)
y = 16 + 4
y = 20
(8, 20)
From our calculations, the third option (8, 20) is the correct ordered pair that would fill in the missing values x and y.

3d + 5s = 25.05
4d + 2s = 13.8
we can do this by combining both equations so that they is only one variable left.
e.g. multiply equation 1 by 4 and equation 2 by 3, and then subtract equation 2 from equation 1 :
12d + 20s = 100.2
- 12d + 6s = 41.4
------------------------------
0 14s = 58.8
s = 58.8/14 = $4.20
3d + 5s = 25.05
3d + 5×4.2 = 25.05
3d + 21 = 25.05
3d = 4.05
d = 4.05/3 = $1.35

(b) the amount of GST on the stamp in 2010,
(c) the percentage increase in amount of GST on the stamp from 1996 to 2010.
Answers
Based on the price of the stamp in 1996, and the increase in 2010, the following are true:
a. price in 2010 = $7,875.b. amount of GST on the stamp in 2010 = $515.19c. percentage increase in GST from 1996 to 2010 = 405%.How much has the price of the stamp changed in 2010?The price in 2010 was:
= 3,500 x 225/100
= $7,875
The GST in 2010 is:
= (7,875 / 1.07) x 7%
= $515.19
The GST in 1996 is:
= (3,500 / 1.03) x 3%
= $101.94
The increase in the GMT is:
= (515.19 - 101.94) / 101.94

The multiplicative rate is 9 if the table that shows an exponential function option fourth is correct.
What is an exponential function?It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x
where a is a constant and a>1
We have a table that shows an exponential function.
As we know the exponential function:
y = a(b)ˣ
Plug x = 1, y = 6
6 = ab ...1
Plug x = 2, y = 4
4 = ab² ...2
Divide equations 1 and 2
ab²/ab = 4/6
b = 2/3
Plug the value of b in the 1 equation.
a(2/3) = 6
a = 9
y = 9(2/3)×
The multiplicative rate = 9
Thus, the multiplicative rate is 9 if the table that shows an exponential function option fourth is correct.

Since the second equation is already solved for y, we can easily use the substitution method.
Substitute y in the first equation with x/3 - 3
2x + 3(x/3 - 3) = 6
2x + x - 9 = 6
3x = 15
x = 5
Now use the second equation, and x = 5, to solve for y.

Answers
Answer:
A) y = –3x+8
Step-by-step explanation:
first off, a negative equation means the graph is downward sloping from left to right –> \. So with this in mind you can immediately eliminate C and D because they are upward sloping graphs. B also doesn't work because it doesn't go through (3,–1). This leaves A as the right answer
the constant number is the number on the y-axis. So, for –3x+2, +2 is the y-coordinate on the y-axis. the slope is -3x meaning down 3, right 1. –3x+8 is the only answer that is perpendicular.
