Amount of pretzel each person receives is 17/16 lb.

Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.

Here, a is called the numerator and b is called the denominator.

Total weight of the bag of pretzels = 34 ounce

Elisa shares this among her two sisters equally.

Share of pretzels each sister gets = 34 / 2 = 17 ounces

We need this amount in pounds.

We know that,

16 ounce = 1 lb.

17 ounces = 17/16 lb.

Hence the amount of pretzels each get is  17/16 lb.

The length of the entire tunnel is 127.88 meters by using cosine law or formulae.

Here we can use the formulae of cosine when two sides a and b and angle between then is given we can apply it.

\(c^{2} =a^{2} +b^{2} -2ab cos (\alpha )\)

Let us take surveyor as point A

one end of the tunnel denoted by point B

other end of the tunnel denoted by point C.

The length of AB is 101 meters

length of AC is 120 meters.

Measure of angle at point A = 42° + 28° =70°

Now lets find the length of tunnel

Answer:\(98.13\ \text{or}\ 261.87^{\circ}\)

Step-by-step explanation:

Given

\(\cos \beta =-\dfrac{\sqrt{2}}{10}\)

As the value of cosine is negative, therefore the angle must lie in II or III quadrant

\(\Rightarrow \beta =\cos^{-1}(-\dfrac{\sqrt{2}}{10})\\\Rightarrow \beta=\cos^{-1}(-0.14142)\\\Rightarrow \beta =98.13^{\circ}\ \text{or}\ 270^{\circ}-8.13\\\Rightarrow \beta=98.13^{\circ}\ \text{or}\ 261.87^{\circ}\)

Given:

13 is the final answer.

The Answer:

B. $12.60

Answer:

The answer would be B.

Step-by-step explanation:

So first what you would do is find what ONE toy car costs, so you would divide 4.20 by 5, which equals 0.84. Then you'd multiply what ONE toy car costs by the amount of toy cars you want to buy, which in this case is 15. 15 times 0.84 is equal to 12.60

The mass that would produce critical damping is \(6.75 kg.\)

The mass that would produce critical damping
Given:
- Spring constant (k) can be calculated using Hooke's Law: F = kx, where F is the force applied, x is the displacement from the natural length, and k is the spring constant.
- Damping constant (c) is 9.
- The spring is stretched 2.5 meters beyond its natural length by a force of 7.5 Newtons.
First, let's find the spring constant (k):
\(7.5 N = k * 2.5 m\)
\(k = 7.5 N / 2.5 m\)
\(k = 3 N/m\)
Now, we can find the mass (m) that would produce critical damping. The formula for critical damping is:
\(c = 2 * sqrt(m * k)\)
where c is the damping constant and m is the mass. We'll solve for m:
\(9 = 2 * sqrt(m * 3)\)
\(9 / 2 = sqrt(3m)\)
\((9 / 2)^2 = 3m\)
\(81 / 4 = 3m\)
\(m = (81 / 4) / 3\)
\(m = 27 / 4\)
\(m = 6.75 kg\)
The mass that would produce critical damping is \(6.75 kg.\)

The series `∑bn` converges if and only if `∑cn` converges, since both series are positive. We know that `∑cn` is a p-series with `p = 5 > 1`, and hence, converges. Therefore, `∑bn` also converges.

Let's first write the definition of the absolute value of a number x: |x|=x, if x≥0; |x|=−x, if x<0.

Here, we assume that `|an / 1an|` converges to `rho = 17`.

Therefore, 17 - ε < |an / 1an| < 17 + ε, for all ε > 0.

Dividing both sides by 17 and taking reciprocals, we have:

`1/(17 + ε) < 1/|an / 1an| < 1/(17 - ε)`Let `bn = n^5an`.

Since `bn` is the product of `n^5` and `|an / 1an|`, the limit of `|bn / 1bn|` is the same as the limit of `|an / 1an|`, which is 17.

Now, we use the Limit Comparison Test to determine the convergence of the series `∑bn` since `bn` is positive for all n. Let `cn = n^5`.

Then, the limit of `|bn / 1cn|` is: `lim (n → ∞) |bn / 1cn| = lim (n → ∞) |an / 1an| = 17`.

The given series

will converge.

The p-series test is used to check the convergence of a series of the form

∑n^p. If p > 1,

the series converges, otherwise, it diverges.

Given that ∣∣∣an 1an∣∣∣ converges to rho = 17.

We need to determine what can be said about the convergence of the given series i.e

[infinity]∑n=1bn=[infinity]∑n=1n^5an.

We know that if ∣an∣ converges then the series ∑an converges as well. Here, we have

∣∣∣an 1an∣∣∣ = 1/∣∣∣an∣∣∣ → 1/17

We know that the given series

\([infinity]∑n=1bn=[infinity]∑n=1n^5an\)

is a product of ∑n^5 and ∣∣∣an 1an∣∣∣ series, i.e,

∑n^5*∣∣∣an 1an∣∣∣.

So, by comparison test, we can say that if  ∑n^5 converges, then the given series  ∑n^5an will also converge.

Let's check if  ∑n^5 converges or not using the p-series test,

\(∑n^5 = ∞∑n=1 1/n^-5 = ∞∑n=1 n^5∞∑n=1 1/n^-5 = ∞∑n=1 n^-5\)

Since p = 5 > 1, ∑n^5 is a convergent series.

Answer: 11

Step-by-step explanation:

This is a problem of solving word problems using systems of equations.

Let's denote 2-seat tables by x and 4-seat tables by y. Therefore, their sum will be the total number of tables, which is 28. So, x + y = 28.

Now, let's concentrate on the number of customers. It says that 'when all tables are full, there will be 90 customers in the restaurant'. Therefore if we seat 2 people on each 2-seat table(x), their total number will be 2x and if we seat 4 people on each 4-seat number(y), their total number will be 4y. Hence, 2x + 3y = 90.

Now, we have a system with two equations:

\(\left \{ {{x + y = 28} \atop {2x + 4y = 90}} \right.\)

Multiply the first line by -4.

\(\left \{ {{-4x -4y = -112} \atop {2x + 4y = 90}} \right.\)

Now, by adding up these two equations, we get the following:

-2x = -22

x = 11

This means that the restaurant has 11 two-seat tables.

The probability that the defective product came from the plant C is 0.4412 or 44.12%

This was solved using Bayes Theorem.

Bayes Theorem is expressed as:

P (C |D) = P(D | C) x P(C)/P(D)

P (C |D) = Probability that the devective product is ffom Plant C

P (D| C) = probablity that a product from Plant C is devective

This is given as 1-0.85

= 0.15


P(C) = Probability a product is from Plant C= 0.5

P(D) = probability a product is defective


P (D  = P (D |  A) x P(A) +   P( D |B) * P (B ) + P(D |C) x P (C)

So we say

P(D|A) = 1  -0.75 =  0.25
P(A)  =  0.35
P( D|B) = 1-0.95 = 0.05; and
P(B)  = 0.15

Next we say based on the ab ove that:

P(D) =  0.25 x0.35  + 0.05 x0.15  + o.15 x  0.5

P D)= 0.17


So puting this into the Bayes Formula:

P (C|D) = 0.15 x 0.5/0.17

P (C|D = 0.44117647058
P (C|D) \(\approx\) 0.4412


Thus, the probability that the defective product came from plact C is 44.12%

(a) h'(4) = 2

(b) h'(4) = -14

(c) h'(4) = -26/25

(d) h'(4) = 26/11  Value of function h(x)

To find h'(4), we need to differentiate the given functions with respect to x and then evaluate them at x = 4.

(a) h(x) = 2f(x) + 5g(x)

To find h'(x), we differentiate each term separately using the sum rule:

h'(x) = 2f'(x) + 5g'(x)

Substituting x = 4:

h'(4) = 2f'(4) + 5g'(4)

       = 2(-4) + 5(2)

       = -8 + 10

       = 2

Therefore, h'(4) = 2.

(b) h(x) = f(x)g(x)

To find h'(x), we use the product rule:

h'(x) = f'(x)g(x) + f(x)g'(x)

Substituting x = 4:

h'(4) = f'(4)g(4) + f(4)g'(4)

       = (-4)(5) + (3)(2)

       = -20 + 6

       = -14

Therefore, h'(4) = -14.

(c) h(x) = f(x)/g(x)

To find h'(x), we use the quotient rule:

h'(x) = (f'(x)g(x) - f(x)g'(x)) / (g(x))^2

Substituting x = 4:

h'(4) = (f'(4)g(4) - f(4)g'(4)) / (g(4))^2

       = (-4)(5) - (3)(2) / (5)^2

       = -20 - 6 / 25

       = -26 / 25

Therefore, h'(4) = -26/25.

(d) h(x) = g(x)/f(x) + g(x)

To find h'(x), we use the sum and quotient rules:

h'(x) = (g'(x)f(x) - g(x)f'(x)) / (f(x))^2 + g'(x)

Substituting x = 4:

h'(4) = (g'(4)f(4) - g(4)f'(4)) / (f(4))^2 + g'(4)

       = (2)(3) - (5)(-4) / (3)^2 + 2

       = 6 + 20 / 9 + 2

       = 26 / 11

Therefore, h'(4) = 26/11.

To summarize:

(a) h'(4) = 2

(b) h'(4) = -14

(c) h'(4) = -26/25

(d) h'(4) = 26/11
