Q4) Let x denote the time taken to run a road race. Suppose x is approximately normally distributed with a mean of 190 minutes and a standard deviation of 21 minutes. If one runner is selected at random, what is the probability that this runner will complete this road race: In less than 160 minutes? * 0.764 0.765 0.0764 0.0765 In 215 to 245 minutes? * 0.1128 O 0.1120 O 0.1125 0.1126
a. The probability that this runner will complete this road race: In less than 160 minutes is 0.0764. The correct answer is C.
b. The probability that this runner will complete this road race: In 215 to 245 minutes is 0.1125 The correct answer is C.
a. To find the probability for each scenario, we'll use the given normal distribution parameters:
Mean (μ) = 190 minutes
Standard Deviation (σ) = 21 minutes
Probability of completing the road race in less than 160 minutes:
To calculate this probability, we need to find the area under the normal distribution curve to the left of 160 minutes.
Using the z-score formula: z = (x - μ) / σ
z = (160 - 190) / 21
z ≈ -1.4286
We can then use a standard normal distribution table or statistical software to find the corresponding cumulative probability.
From the standard normal distribution table, the cumulative probability for z ≈ -1.4286 is approximately 0.0764.
Therefore, the probability of completing the road race in less than 160 minutes is approximately 0.0764. The correct answer is C.
b. Probability of completing the road race in 215 to 245 minutes:
To calculate this probability, we need to find the area under the normal distribution curve between 215 and 245 minutes.
First, we calculate the z-scores for each endpoint:
For 215 minutes:
z1 = (215 - 190) / 21
z1 ≈ 1.1905
For 245 minutes:
z2 = (245 - 190) / 21
z2 ≈ 2.6190
Next, we find the cumulative probabilities for each z-score.
From the standard normal distribution table:
The cumulative probability for z ≈ 1.1905 is approximately 0.8820.
The cumulative probability for z ≈ 2.6190 is approximately 0.9955.
To find the probability between these two z-scores, we subtract the cumulative probability at the lower z-score from the cumulative probability at the higher z-score:
Probability = 0.9955 - 0.8820
Probability ≈ 0.1125
Therefore, the probability of completing the road race in 215 to 245 minutes is approximately 0.1125. The correct answer is C.

classify each of the equations above as separable, linear, exact, can be made exact, bernoulli, riccatti, homogeneous, linear combination, or neither.
To classify the equations as separable, linear, exact, can be made exact, Bernoulli, Riccatti, homogeneous, linear combination, or neither, you will need to identify the type of differential equation present.
Below are the classifications of each equation:
1. dy/dx = 5x²
This is a separable differential equation since it can be written as: dy = 5x² dx, and both variables can be separated.
2. y' + 2xy = x²
This is a linear differential equation since it can be written in the form of y' + p(x)y = q(x), where p(x) = 2x and q(x) = x².
3. (2x + 1) dx - (3y + 1) dy = 0
This differential equation is not linear and not separable, so it must be classified using other methods.
4. (2xy - y³) dx + (x² - 3y²) dy = 0
This is an exact differential equation since the partial derivatives of M and N are equal.
5. 3y' + 2ty = t²
This is a linear differential equation that can be solved using an integrating factor.
6. y' - y/x = x³
This is a Bernoulli differential equation since it can be written in the form of y' + p(x)y = q(x)yn, where n ≠ 1 and q(x) = x³.
7. y' = 2xy² + 3x
This is a Riccati differential equation since it can be written in the form of y' = p(x)y² + q(x)y + r(x), where p(x) = 2x, q(x) = 0, and r(x) = 3x.
8. (x² - y²) dx - 2xy dy = 0
This is a homogeneous differential equation since it can be written in the form of M(x,y)dx + N(x,y)dy = 0 and both M and N are homogeneous functions of the same degree.
9. y'' + 2y' + y = x + 1
This is a linear combination of homogeneous solutions and particular solutions since it can be solved using both techniques.

You have a rectangular prism cake with dimensions of 16 inches long, 12 inches wide and 3 inches tall. If we keep the height of 3 inches, what does the width of a round cake need to be to keep the same volume? (A round cake is a cylinder with a height of 3)
The width of the round cake needs to be approximately 2 times the radius, or about 15.6 inches, to have the same volume as the rectangular prism cake.
What is rectangular prism and cylinder?A three-dimensional structure with six rectangular faces that are parallel and congruent together is called a rectangular prism. It has a length, width, and height. By multiplying the length, width, and height together, one may get the volume. Contrarily, a cylinder is a three-dimensional shape with two congruent and parallel circular bases. It has a height and a radius, and you can determine its volume by dividing the base's surface area by the object's height. A cylinder has curved edges and no corners while a rectangular prism has straight edges and corners.
The volume of the rectangular cake is given as:
V = length * width * height
Substituting the values we have:
16 * 12 * 3 = 576 cubic inches
Now, for the cylindrical cake to be of the same volume we have:
V = π * radius² * height
π * radius² * 3 = 576
(3.14) * radius² * 3 = 576
radius = 15.6 inches
Hence, the width of the round cake needs to be approximately 2 times the radius, or about 15.6 inches, to have the same volume as the rectangular prism cake.

Find the area of the shaded region. The graph depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15 (as on the Wechsler test).
Answer:
A) 0.7938---------------------------
Givenμ = 100, σ = 15Find the area between x = 85 and x = 125.
Find z-scores for each endz = (x - μ)/σz₁ = (85 - 100)/15 = - 15/15 = - 1z₂ = (125 - 100)/15 = 25/15 ≈ 1.67Find the corresponding probabilities from z-score tablez₁ = 0.1587z₂ = 0.9525Find the differencez₂ - z₁ = 0.9525 - 0.1587 = 0.7938The matching choice is A
Answer:
0.7938
Step-by-step explanation:
The given graph is a normal distribution curve.
If a continuous random variable X is normally distributed with mean μ and variance σ²:
\(\boxed{X \sim \textsf{N}(\mu,\sigma^2)}\)
Given:
mean μ = 100standard deviation σ = 15\(\text{If \; $X \sim \textsf{N}(100,15^2)$,\;\;find\;\;P$(85\leq X\leq 125)$\;\;to\;3\;s.f.}\)
Therefore, we need to find the area to the left of x = 125 and subtract the area to the left of x = 85.
Method 1
Using a calculator:
\(\begin{aligned}\implies \text{P}(85\leq X\leq 125)&= \text{P}(X\leq 125)-\text{P}(X < 85)\\&=0.9522096477-0.1586552539 \\&=0.7935543938\\&\approx0.7938\end{aligned}\)
Method 2
Converting to the z-distribution.
\(\boxed{\text{If\;\;$X \sim$N$(\mu,\sigma^2)$\;\;then\;\;$\dfrac{X-\mu}{\sigma}=Z$, \quad where $Z \sim$N$(0,1)$}}\)
\(x=85 \implies Z_1=\dfrac{85-100}{15}=-1\)
\(x=125 \implies Z_2=\dfrac{125-100}{15}=1.67\)
Using the z-tables to find the corresponding probabilities (see attachments).
\(\begin{aligned}\implies \text{P}(-1\leq Z\leq 1.67)&= \text{P}(Z\leq 1.67)-\text{P}(Z < -1)\\&=0.9525-0.1587\\&=0.7938\end{aligned}\)

18. If f(x) = arccos(x^2), then f'(x) =
The derivative of f(x) = arccos(x^2) is: f'(x) = -2x / √(1-x^4)
The derivative of f(x) = arccos(x^2), we'll use the chain rule. The chain rule states that the derivative of a composite function is the derivative of the outer function times the derivative of the inner function. In this case, the outer function is arccos(u) and the inner function is u = x^2.
First, let's find the derivative of the outer function, arccos(u). The derivative of arccos(u) is -1/√(1-u^2). Next, we'll find the derivative of the inner function, x^2. The derivative of x^2 is 2x.
Now we'll apply the chain rule. We have:
f'(x) = (derivative of outer function) * (derivative of inner function)
f'(x) = (-1/√(1-u^2)) * (2x)
Since u = x^2, we'll substitute that back into our equation:
f'(x) = (-1/√(1-x^4)) * (2x)
So, the derivative of f(x) = arccos(x^2) is:
f'(x) = -2x / √(1-x^4)

Jenny has some nickels and some
dimes. The value of the coins is $1.65.
There are 12 more nickels than dimes.
How many of each kind of coins does
Jenny have?
Answer:
7 dimes and 19 nickels
Step-by-step explanation:
d = dimes
n = nickels
The total amount is
.05n + .1d =1.65
He has 12 more nickels than dimes
12+d = n
Substitute this into the first equation
.05 (12 +d) + .1d =1.65
.6 + .05d +.1d = 1.65
Combine like terms
.6 + .15d = 1.65
Subtract .6 from each side
.15d = 1.65-.6
.15d = 1.05
Divide by .15
.15d/.15 = 1.05/.15
d = 7
Now find n
12+d = n
12+7 = n
19 = n
Answer:
19 nickels and 7 dimes
Step-by-step explanation:
0.05n + 0.10d = 1.65
d+12=n
0.05(d+12) +0.010d = 1.65
0.05d + 0.6 + 0.10d = 1.65
0.15d = 1.05
d = 7 dimes
d+12=n
7+12=n

Find the area of the shape below:
NOTE: The figure is NOT drawn to scale
Answer:
Find the rectangle's area on the left hand side, using the formula:
A = l x w
Where 'l' represents the length and 'w' stands for the width.
Plug in what you know:-
A = l x w
A = 15 x 5
A = 75 square units is the area of the left rectangle.
Now let's find the rectangle's area on the right hand side, using the formula:
A = l x w
Where 'l' represents the length and 'w' stands for the width.
A = l x w
A = 15 x 4
A = 60 square units is the area of the right rectangle.
Now find the middle small horizontal rectangle's area, using the formula:
A = l x w
Where 'l' represents the length and 'w' stands for the width.
But, let's figure out the length first.
We know that from the left rectangle, the two side lengths beside the unknown length of the middle rectangle area 5 and 7.
The unknown length plus those two lengths (5&7) will have to equal 15 since that is the total length, so;
15 - (5 + 7) = x
15 - 12 = x
3 = x, so the unknown length of the middle rectangle is 3.
Plug in what you know into the formula:
A = l x w
A = 3 x 7
A = 21 square units is the area of the middle rectangle.
Now add up all the areas together:
75 + 60 + 21
= 156 square units is the area of the shape.
.Problem 2 1 (a) Let RS be an onto homomorphism of rings. Let I be an ideal of R. Show that f(1) = f(alaen) is an ideal of S (check additive subgroup and ideal condition). (b) Recall the substitution homomorphism pvz : Q[x] - [V2] given by va (p(x)) = p(72) You can assume this is a homomorphism. (1) Show Hv2 is onto. (ii) Express Ker Hz as a principal ideal of Q[x] Gustify). (iii) What conclusion can be drawn using FHT (the Fundamental Homomorphism Theorem)?
The required answers are:
a. \(f(1) = f(1_R)\) is an ideal of S.
b. i) It is shown that \(\phi\) is onto.
ii) \(Ker(\phi)\) = {0}, and it is a principal ideal of \(Q[x]\) generated by the zero
polynomial
iii) \(Q[x]/Ker(\phi)\) is isomorphic to \(Q[x]\).
a) To show that \(f(1) = f(1_R)\) is an ideal of \(S\), to check two conditions: it is an additive subgroup of \(S\), and for any element s in f(1) and any element r in S, the product \(rs\) and \(sr\) are both in \(f(1)\).
Additive Subgroup:
Since f is an onto homomorphism of rings, it preserves addition. Therefore, \(f(1)\) contains the identity element of S, which is \(f(1_R)\).
For any two elements \(s, t\) in \(f(1)\) , gives \(s = f(r)\) and \(t = f(t')\) for some elements \(r, t'\) in \(R\).
Then, \(s - t = f(r) - f(t') = f(r - t')\) which belongs to f(1) since \(R\) is an ideal of \(R\).
Ideal Condition:
Let \(s\) be an element in \(f(1)\)and r be an element in \(S\).
Then, \(s = f(r')\) for some element \(r'\) in \(R\).
Thus, \(rs = f(r')r\), which belongs to \(f(1)\) since \(R\) is an ideal of \(R\).
Similarly, sr = rf(r') also belongs to f(1) since \(R\) is an ideal of \(R\).
Therefore, \(f(1) = f(1_R)\) is an ideal of S.
(b) Now let's consider the substitution homomorphism \(pvz: Q[x] \c- R\) given by \(\phi(p(x)) = p(\sqrt{2} )\).
(i) To show that \(\phi\) is onto, to show that for any element a in ℝ, there exists an element p(x) in Q[x] such that \(\phi(p(x)) = p(\sqrt{2} ) = a.\)
Let's take \(p(x) = x - a\). Then, \(\phi(p(x)) = (\sqrt{2} - a)\).
Since \(\sqrt{2} - a\) is a real number, Thus shown that \(\phi\) is onto.
(ii) The kernel of φ, denoted by \(Ker(\phi)\), consists of all polynomials p(x) in \(Q[x]\) such that \(\phi(p(x)) = p(\sqrt{3} ) = 0.\)
In other words, \(Ker(\phi)\) is the set of all polynomials in \(Q[x]\) whose root is \(\sqrt{2}\). Since \(\sqrt{2}\) is irrational, the only polynomial in \(Q[x]\) with \(\sqrt{2}\) as a root is the zero polynomial.
Therefore, \(Ker(\phi) =\){0}, and it is a principal ideal of \(Q[x]\) generated by the zero polynomial.
(iii) The Fundamental Homomorphism Theorem (FHT) states that for any homomorphism \(\phi: R \c- S\), the image of \(\phi\) is isomorphic to the quotient ring \(R/Ker(\phi)\).
In this case, the image of \(\phi\) is \(R\) and the kernel \(Ker(\phi)\) is {\({0}\)}.
Since \(Ker(\phi)\) is the zero ideal, the quotient ring \(R/Ker(\phi)\) is isomorphic to R itself.
Therefore, \(Q[x]/Ker(\phi)\) is isomorphic to \(Q[x]\).
Hence, the required answers are:
a. \(f(1) = f(1_R)\) is an ideal of S.
b. i) It is shown that \(\phi\) is onto.
ii) \(Ker(\phi)\) = {0}, and it is a principal ideal of \(Q[x]\) generated by the zero polynomial.
iii) \(Q[x]/Ker(\phi)\) is isomorphic to \(Q[x]\)
