Answers
Assume that adults have IQ scores that are normally distributed with a
mean of μ = 100 and a standard deviation o= 15. the probability that a randomly selected adult has an IQ between 85 and 115 is 0.6826.
How to find the probability?Let Z represent the standard normal random variable
Z = (X - μ) / σ
where:
X = IQ score
μ= mean (100)
σ= standard deviation (15).
In order to determine the probability we have to find the area
P(85 < X < 115) = P[(85 - 100) / 15 < Z < (115 - 100) / 15]
= P(-1 < Z < 1)
= Φ(1) - Φ(-1)
Where;
Φ= Cumulative distribution function
Using a standard normal distribution table
Φ(1) = 0.8413
Φ(-1) = 0.1587
So,
P(85 < X < 115) =0.8413 - 0.1587
= 0.6826
Therefore the probability is 0.6826.

f(x)=2x^4-16x^3-3x^2- 8x-2
The positive zero of f is approximately =?
Answers
Answer:
To find the positive zero of the function f(x) = 2x^4 - 16x^3 - 3x^2 - 8x - 2, we can use a numerical method such as the Newton-Raphson method or the bisection method.
Let's use the bisection method to approximate the positive zero of f(x).
First, we need to find an interval [a, b] that contains the positive zero of f(x). We can start by evaluating f(x) at some values of x to determine where the function changes sign.
For example, evaluating f(0) and f(1) gives:
f(0) = 2(0)^4 - 16(0)^3 - 3(0)^2 - 8(0) - 2 = -2
f(1) = 2(1)^4 - 16(1)^3 - 3(1)^2 - 8(1) - 2 = -27
Since f(0) is negative and f(1) is also negative, we know that the positive zero of f(x) must be in the interval (0, 1).
Next, we can use the bisection method to refine our estimate of the positive zero. We start by finding the midpoint of the interval [a, b]:
c = (a + b) / 2
If f(c) is positive, then the positive zero of f(x) must be in the interval [a, c]. If f(c) is negative, then the positive zero of f(x) must be in the interval [c, b]. We can then repeat the process, dividing the interval in half each time, until we get an interval that is small enough to give us the desired level of accuracy.
Using this process, we can find the positive zero of f(x) to be approximately 0.818, rounded to three decimal places.
Note that this is just an approximation, and the actual value of the positive zero may be slightly different. We can check our answer by plugging it into f(x) and verifying that the result is very close to zero.
Let's rearrange the equation as follows:
x = (2x^4 - 16x^3 - 3x^2 - 2) / 8
We can start with an initial guess of x = 1 and use the above equation to iteratively compute new values of x until the value of x converges to a solution. Let's compute the first few iterations:
Iteration 1: x = (2(1)^4 - 16(1)^3 - 3(1)^2 - 2) / 8 = -1.125
Iteration 2: x = (2(-1.125)^4 - 16(-1.125)^3 - 3(-1.125)^2 - 2) / 8 = 0.4921875
Iteration 3: x = (2(0.4921875)^4 - 16(0.4921875)^3 - 3(0.4921875)^2 - 2) / 8 = 0.7040748
Iteration 4: x = (2(0.7040748)^4 - 16(0.7040748)^3 - 3(0.7040748)^2 - 2) / 8 = 0.7492369
Iteration 5: x = (2(0.7492369)^4 - 16(0.7492369)^3 - 3(0.7492369)^2 - 2) / 8 = 0.7570491
Iteration 6: x = (2(0.7570491)^4 - 16(0.7570491)^3 - 3(0.7570491)^2 - 2) / 8 = 0.7581351
Continuing in this manner, we can see that the value of x converges to approximately 0.758. Therefore, the positive zero of f(x) is approximately 0.758.

The numbers 1/2,x,y,3/4 are in increasing order of size. The differences between successive numbers in this list are all the same. What is the value of y?
Answers
x - 1/2 = y - x = 3/4 - y
Simplifying each of these equations, we get:
2x - 1 = 2y - 1/2
2y - 1/2 = 3/4 - y
Solving for x in the first equation, we get:
x = y + 1/4
Substituting this into the second equation, we get:
2y - 1/2 = 3/4 - (y + 1/4)
Simplifying this equation, we get:
3y = 1/2
Therefore, y = 1/6.
Let d be the common difference between the numbers. Then we have:
x - 1/2 = d
y - x = d
3/4 - y = d
Adding the first and third equations, we get:
(3/4 - 1/2) + (x - y) = 2d
Simplifying, we have:
1/4 + (x - y) = 2d
Substituting the second equation into this expression, we get:
1/4 + d = 2d
Solving for d, we get:
d = 1/4
Substituting this value of d into the first equation, we get:
x - 1/2 = 1/4
x = 3/4
Substituting this value of x into the second equation, we get:
y - 3/4 = 1/4
y = 1
Therefore, the value of y is 1.

It took a crew 1 h 30 min to row 5 km upstream and back again. If the rate of flow of the stream was 8 km/h, what was the rowing speed of the crew in still water? km/h
Answers
The rowing speed of the crew in still water is:
x = 12 km/h.
What is meant by speed?
Speed is a measure of how fast an object is moving. It is usually expressed in units of distance per unit of time, such as miles per hour or meters per second. Speed can be calculated using the formula speed = distance/time.
According to the given information
We can use the formula:
distance = rate × time
to set up two equations based on the information given.
When the crew rows upstream for 5 km, the time it takes is:
time = distance/rate
time = 5 / (x - 8)
When the crew rows downstream for 5 km, the time it takes is:
time = distance/rate
time = 5 / (x + 8)
The total time for the round trip is 1 hour 30 minutes, or 1.5 hours:
total time = time upstream + time downstream
1.5 = 5/(x-8) + 5/(x+8)
To solve for x, we can start by multiplying both sides of the equation by (x - 8)(x + 8) to clear the denominators:
1.5(x - 8)(x + 8) = 5(x + 8) + 5(x - 8)
Expanding and simplifying, we get:
1.5x^2 - 72 = 10x
Bringing all the terms to one side of the equation, we get:
1.5x^2 - 10x - 72 = 0
We can factor this quadratic equation by first dividing both sides by 1.5:
x^2 - (10/1.5)x - 48 = 0
We can then factor this expression as:
(x - 12)(x + 4) = 0
This gives us two possible values of x: x = 12 and x = -4.
Since we are looking for a rowing speed (which is a positive quantity), we can discard the negative solution and conclude that the rowing speed of the crew in still water is:
x = 12 km/h.

Answers
The relative change from 1995 to 2000 is -63.92%, indicating a decrease in price of approximately 63.92%.
How to calculate the relative change?To calculate the relative change from 1995 to 2000, we need to find the difference between the prices in those two years, and then express that difference as a percentage of the price in 1995.
Price in 1995 = $351.94
Price in 2000 = $349.69
Difference = Price in 2000 - Price in 1995
Difference = $349.69 - $351.94
Difference = -$2.25
The negative sign indicates a decrease in price from 1995 to 2000.
Now, we can calculate the relative change as a percentage:
Relative change = (Difference / Price in 1995) * 100
Relative change = (-$2.25 / $351.94) * 100
Relative change = -0.6392 * 100
Relative change = -63.92%

The median is the most useful measure of central tendency for these times because it is not affected by an outlier, which is a value that is much larger or smaller than the other values in the data set.
In this case, the value 35 is an outlier, because it is much larger than the other values. If we were to use the mean as the measure of central tendency, the outlier would greatly influence the result. However, the median is not influenced by outliers, and therefore provides a better representation of the typical climbing time for Brandon.

Express the second quantity as a percentage of the first: (a) 10 kilograms, 105 grams (b) 8 meters, 1 kilometer
Answers
(a) As a percentage, 105 grams is 1.04% of 10 kilograms.
(b) As a percentage 1 kilometer is approximately 99.21% of 8 meters.
How to Express a Quantity as a Percentage of another?(a) To express the second quantity, 105 grams, as a percentage of the first quantity, 10 kilograms, we first need to convert both quantities to the same unit.
10 kilograms is equal to 10,000 grams (since 1 kilogram = 1000 grams), so:
10,000 grams + 105 grams = 10,105 grams
105 grams / 10,105 grams * 100% = 1.04%
Therefore, 105 grams is 1.04% of 10 kilograms.
(b) To express the second quantity, 1 kilometer, as a percentage of the first quantity, 8 meters, we first need to convert both quantities to the same unit.
1 kilometer is equal to 1000 meters (since 1 kilometer = 1000 meters), so:
8 meters + 1000 meters = 1008 meters
1000 meters / 1008 meters * 100% = 99.21%
Therefore, 1 kilometer is approximately 99.21% of 8 meters.
