Assume that adults have IQ scores that are normally distributed with a mean of μ=100 and a standard deviation σ=20. Find the probability that a randomly selected adult has an IQ less than 128.
Answers
The probability that the IQ is less than 128 is 0.91924
How to determine the probability?The given parameters about the distribution are
Mean value of the set of data, μ = 100Standard deviation value of the set of data σ = 20IQ value, x = 128The z-score of the data value is calculated as
z = (x - μ)/σ
Substitute the given parameters in the above equation
z = (128 - 100)/20
Evaluate
z = 1.4
The probability that the IQ is less than 128 is then calculated as:
P(x < 128) = P(z < 1.4)
From the z table of probabilities, we have;
P(x < 128) = 0.91924
Hence, the probability is 0.91924

the receipt you are using indicate that a mixture should be heated to a temperature of 132F.The mixture is currently at 109F. how many more degrees d does the mixture need to be heated
Answers
The mixture must be heated an amount of 23 °F to reach a temperature of 132 °F.
How much must the receipt be heated to be at recommended temperature?
Temperature is the measure of how "hot" a system is. Physically speaking, temperature is closely related to atomic and molecular motion within a system. In this problem we find a mixture that must be at a certain temperature, higher than its real one.
Therefore, the amount required to increase the temperature of the mixture is defined by following subtraction:
ΔT = R - r
Where:
ΔT - Temperature difference, in degrees Fahrenheit.r - Real temperature, in degrees Fahrenheit.R - Expected temperature, in degrees Fahrenheit.If we know that r = 109 °F and R = 132 °F, then the temperature difference is:
ΔT = 132 °F - 109 °F
ΔT = 23 °F

The difference two positive integer is 3. If the smaller is added to the square of the larger the sun is 417 find the integers
Answers
Answer:
\(17\) and \(20\).
Step-by-step explanation:
Let \(x\) denote the larger one of the two positive integers (\(x > 0\).) The smaller integer would be \((x - 3)\). The square of the larger integer would be \(x^{2}\).
The sum of the smaller integer and the square of the larger integer is \((x^{2} + (x - 3))\). If this sum is equal to \(417\), then:
\(x^{2} + x - 3 = 417\).
\(x^{2} + x - 420 = 0\).
Solve this quadratic equation for \(x\) through factorization. Since \(420 = 21 \times 20\):
\(x^{2} + x - (21 \times 20) = 0\).
\(x^{2} + 21\, x - 20\, x + (21)\, (-20) = 0\).
\((x + 21)\, (x - 20) = 0\).
Thus, either \(x = 20\) or \(x = (-21)\) by the Factor Theorem. However, since \(x > 0\) (the two integers are both positive,) only \(x = 20\) is a valid solution.
Hence, the larger one of the two integers would be \(20\). The smaller one of the two integers would be \((x - 3) = (20 - 3) = 17\).

A tank is full of water. Find the work (in ft-lb) required to pump the water out of the spout. Use the fact that water weighs 62.5 lb/ft3. (Round your answer to the nearest whole number.) 3 ft6 ft12 ft A frustum of a cone with a spout is given. The smaller radius is 3 ft, the larger radius is 6 ft, and the height is 12 ft.
Answers
The work required to pump the water out of the spout is approximately 64,307,077 ft-lb
To find the work required to pump the water out of the spout, we need to calculate the weight of the water in the tank and then convert it to work using the formula: work = force × distance.
First, let's calculate the volume of water in the tank. The frustum of a cone can be represented by the formula: V = (1/3)πh(r1² + r2² + r1r2), where r1 and r2 are the radii of the two bases and h is the height.
Given r1 = 3 ft, r2 = 6 ft, and h = 12 ft, we can calculate the volume:
V = (1/3)π(12)(9 + 36 + 18) = 270π ft³
Now, we can calculate the weight of the water using the density of water:
Weight = density × volume = 62.5 lb/ft³ × 270π ft³ ≈ 53125π lb
Next, we convert the weight to force by multiplying it by the acceleration due to gravity (32.2 ft/s²):
Force = Weight × acceleration due to gravity = 53125π lb × 32.2 ft/s² ≈ 1709125π lb·ft/s²
Finally, we can calculate the work by multiplying the force by the distance. Since the water is being pumped out of the spout, the distance is equal to the height of the frustum, which is 12 ft:
Work = Force × distance = 1709125π lb·ft/s² × 12 ft ≈ 20509500π lb·ft ≈ 64307077 lb·ft

Among all pairs of numbers whose sum is 24, find a pair whose product is as large as possible. Show the work(the steps)! Write an equation of the corresponding quadratic function. How parabola opens? What is the maximum product? Does this function has a maximum value or the minimum value? Explain. Graph the function and upload the image.
Answers
The pair of numbers that yields the maximum product when their sum is 24 is (12, 12), and the maximum product is 144. The corresponding quadratic function is P(x) = -x^2 + 24x, and the parabola opens downwards.
To find a pair of numbers whose sum is 24 and whose product is as large as possible, we can use the concept of maximizing a quadratic function.
Let's denote the two numbers as x and y. We know that x + y = 24. We want to maximize the product xy.
To solve this problem, we can rewrite the equation x + y = 24 as y = 24 - x. Now we can express the product xy in terms of a single variable, x:
P(x) = x(24 - x)
This equation represents a quadratic function. To find the maximum value of the product, we need to determine the vertex of the parabola.
The quadratic function can be rewritten as P(x) = -x^2 + 24x. We recognize that the coefficient of x^2 is negative, which means the parabola opens downwards.
To find the vertex of the parabola, we can use the formula x = -b / (2a), where a = -1 and b = 24. Plugging in these values, we get x = -24 / (2 * -1) = 12.
Substituting the value of x into the equation y = 24 - x, we find y = 24 - 12 = 12.
So the pair of numbers that yields the maximum product is (12, 12). The maximum product is obtained by evaluating the quadratic function at the vertex: P(12) = 12(24 - 12) = 12(12) = 144.
Therefore, the maximum product is 144. This quadratic function has a maximum value because the parabola opens downwards.
To graph the function, you can plot several points and connect them to form a parabolic shape. Here is an uploaded image of the graph of the quadratic function: [Image: Parabola Graph]

Step-by-step explanation:
The number of potholes in any given 1 mile stretch of freeway pavement in Pennsylvania has a bell-shaped distribution. This distribution has a mean of 62 and a standard deviation of 11. Using the empirical rule (as presented in the book), what is the approximate percentage of 1-mile long roadways with potholes numbering between 51 and 84?
Answers
- 68% of the data falls within one standard deviation of the mean
- 95% of the data falls within two standard deviations of the mean
- 99.7% of the data falls within three standard deviations of the mean
In this case, we can use the empirical rule to estimate the percentage of 1-mile long roadways with potholes numbering between 51 and 84.
To do this, we need to first calculate the z-scores for the values 51 and 84, using the formula:
z = (x - μ) / σ
where x is the value, μ is the mean, and σ is the standard deviation.
For x = 51:
z = (51 - 62) / 11 = -1
For x = 84:
z = (84 - 62) / 11 = 2
These z-scores tell us how many standard deviations away from the mean each value is. A z-score of -1 means that the value is 1 standard deviation below the mean, and a z-score of 2 means that the value is 2 standard deviations above the mean.
Now, we can use the empirical rule to estimate the percentage of 1-mile long roadways with potholes numbering between 51 and 84:
- The percentage of data within one standard deviation of the mean is approximately 68%. Since the mean is 62 and the standard deviation is 11, one standard deviation below the mean is 51, and one standard deviation above the mean is 73 (62 - 11 = 51, 62 + 11 = 73). Therefore, approximately 68% of the 1-mile long roadways have potholes numbering between 51 and 73.
- The percentage of data within two standard deviations of the mean is approximately 95%. Since two standard deviations below the mean is 40, and two standard deviations above the mean is 84 (62 - 2(11) = 40, 62 + 2(11) = 84), approximately 95% of the 1-mile long roadways have potholes numbering between 40 and 84.
Therefore, the approximate percentage of 1-mile long roadways with potholes numbering between 51 and 84 is approximately 95%.

Answers
We have a sequence where we know that the initial term a0 is 25.
\(a_0=25\)Then, each term adds the common difference of 15, so we can write:
\(a_n=a_{n-1}+15\)The recursive formula for this sequence, representing how much she has in her savings account, is a(n) = a(n-1) + 15.
To find the explicit formula, we relate each term to the first term in order to find the relation:
\(\begin{gathered} a_1=a_0+15=25+15 \\ a_2=a_1+15=(25+15)+15=25+2\cdot15 \\ a_n=25+n\cdot15=25+15n_{} \end{gathered}\)Then, the explicit formula is a(n) = 25 + 15n.

5. Determine the value of t4 in an arithmetic sequence given that t₁ = 11 and S9 = 243.
Answers
The value of t₄ in the arithmetic sequence is 103/8.To determine the value of t₄ in an arithmetic sequence, we need to use the given information that t₁ = 11 (the first term of the sequence) and S₉ = 243 (the sum of the first 9 terms of the sequence).
We know that the formula for the sum of an arithmetic sequence is Sₙ = (n/2)(2a + (n-1)d), where Sₙ is the sum, a is the first term, n is the number of terms, and d is the common difference.
From the given information, we have S₉ = 243, a = 11, and n = 9. Plugging these values into the sum formula, we can solve for d:
243 = (9/2)(2(11) + (9-1)d)
243 = 9(22 + 8d)
243 = 198 + 72d
45 = 72d
d = 45/72 = 5/8
Now that we have the common difference, we can find t₄ using the formula for the nth term of an arithmetic sequence:
tₙ = a + (n-1)d
t₄ = 11 + (4-1)(5/8)
t₄ = 11 + 3(5/8)
t₄ = 11 + 15/8
t₄ = 88/8 + 15/8

In a year when the maximum income for Social Security was $118,500, Bart worked at two jobs. In one job he earned $99,112. In his second job, he earned $56,222.
Both of his employers took out Social Security tax. As a result, Bart had paid excess Social Security tax, and the government must return some of it to him. How
much does the government owe him for excess Social Security paid?
Answers
Answer:
The government owes Bart the excess Social Security tax that he paid, which is the amount of tax he paid on his income above the maximum income for Social Security. In this case, that would be $118,500 (the maximum income for Social Security) minus $99,112 (what he earned at his first job) minus $56,222 (what he earned at his second job) = $13,166. So the government owes Bart $13,166 for the excess Social Security tax he paid.
Answer:
Step-by-step explanation:
He earned a total of 155,334.
99112 plus 56222.
subtract the max income from the income total
155,334 - 118500 = 36834
He is owed the social security tax he paid on 36834.
