Answer:

31.25

Step-by-step explanation:

Answer:

31.25 is right.

Step-by-step explanation:

To calculate the estimated standard error for the sample mean difference (s(m1 - m2)) when given the pooled variance (s2p), we need to use the formula:

s(m1 - m2) = √[(s2p / n1) + (s2p / n2)]

In this case, both samples have the same size, n = 5, so we can substitute n1 = n2 = 5 into the formula.

s(m1 - m2) = √[(40 / 5) + (40 / 5)]

s(m1 - m2) = √[8 + 8]

s(m1 - m2) = √16

s(m1 - m2) = 4

Therefore, the estimated standard error for the sample mean difference (s(m1 - m2)) is 4.

The 2-, 10-, and 100-year peak floods for a normal distribution are 5500 cfs.

Given a mean and standard deviation of 3,500 and 2,000 cfs, respectively, the 2-, 10-, and 100-year peak floods for a normal distribution can be found as follows:

Formula used in finding the peak flood is as follows:

Q_T= Q_m + K_T

σ

Where Q_T is the flow for a given period,

Q_m is the mean flow, K_T is the coefficient of skewness, and σ is the standard deviation of the flows.

For a normal distribution, K_T= frac{\text{duration of period in years}-1}{2}\times\frac{\text{duration of period in years}+1}{2}

Substitute the mean and standard deviation to the formula above:

When the period of interest is 2 years, the coefficient of skewness is calculated below:

[{{K}_{T}}=\frac{\text{(2-1)(2+1)}}{2}=1\]

Also, K_{T} is 1 for the 10-year and 100-year flood.

When these values are computed, we get the following values:

Q_{2}=3500+1(2000)=5500 \text{ cfs}

Q_{10}=3500+1(2000)=5500 \text{ cfs}

Q_{100}=3500+1(2000)=5500 \text{ cfs}

Therefore, the 2-, 10-, and 100-year peak floods for a normal distribution are 5500 cfs.

Set up equation to represent this and solve for g:

Answer:

3/8

Step-by-step explanation:

3 1/3 = 10/3

1 1/4 = 5/4

Remember when dividing by a fraction you can also multiply by its reciprocal meaning flip the numerator and denominator.

so

(3 1/3) / (1 1/4) = (10/3) / (5/4) = (10/3) x (4/5) which is the same as (3/10) x (5/4)

= (3 x 5) / (10 x 4) = 15 / 40

the numerator and denominator have a common factor of 5 so divide the  numerator and denominator by 5

15 / 40 = 3/8

The three values that you need to know in order to perform a z-score are the mean, the standard deviation, and the raw score.

The mean is the average of the data set, the standard deviation measures the spread of the data, and the raw score is the individual data point that you are comparing to the rest of the data set. The z-score formula is:

z = (x - μ) / σ

Where z is the z-score, x is the raw score, μ is the mean, and σ is the standard deviation. By knowing these three values, you can calculate the z-score and determine how many standard deviations away from the mean the raw score is.

Answer:

1. 130

2. 50

Step-by-step explanation:

AEB = 180 because it's supplementary and AEC is vertical to DEB making them congruent. 180-50=130

The measure of angle AED = 130 degrees and the measure of angle DEB = 50 degrees

We have lines AB and CD intersect at E.

We have to find out -

No, straight lines can never intersect at more than one point.

According to the question -

AB and DC intersect each other.

Now -

∠DEB = ∠AEC  (Vertically opposite angles are equal)

Let ∠AED = x

Then -

∠AED = ∠CEB = x  (Vertically opposite angles are equal)

Now -

∠AED + ∠DEB + ∠BEC + ∠AEC = 360

x + 50 + x + 50 = 360

2x + 100 = 360

2x = 260

x = 130

Hence -  the measure of angle AED = 130 degrees and the measure of angle DEB = 50 degrees.

The height of the cylinder is approximately 5.97 cm.

A cylinder is a three-dimensional geometric shape that consists of two parallel, congruent circular bases and a curved lateral surface that connects the bases. The bases are perpendicular to the lateral surface, which means that the lateral surface forms a curved rectangle.

Given;

The circumference of the cylinder is 32π.

The lateral surface area of the cylinder is 750 cm².

Lateral surface area of a cylinder = 2πrh

Circumference of a cylinder = 2πr

We can use the circumference formula to find the radius of the cylinder:

2πr = 32π

r = 16

Now we can use the lateral surface area formula to find the height of the cylinder:

750 = 2π(16)(h)

750 = 32πh

h = 750/(32π)

h ≈ 5.97

As a result, the cylinder's height is around 5.97 cm.

y = mx + b is the slope intercept form of writing the equation of a straight line

Step-by-step explanation:

y = mx + b is the slope intercept form of writing the equation of a straight line. In the equation 'y = mx + b', 'b' is the point, where the line intersects the 'y axis' and 'm' denotes the slope of the line. The slope or gradient of a line describes how steep a line is.

To find a power series representation for \(f(x) = \frac{1}{(1+x)^2}\), we can use the geometric series expansion. By expanding \(\frac{1}{(1+x)^2}\) as a geometric series, we can express it as an infinite sum of powers of \(x\). This representation allows us to approximate the function for a given range of values of \(x\) using a finite number of terms.

The geometric series expansion states that for \(|x| < 1\), the series \(\sum_{n=0}^{\infty} x^n\) converges to \(\frac{1}{1-x}\). We can use this expansion to find a power series representation for \(f(x)\).

First, we rewrite \(f(x)\) as \(\frac{1}{(1+x)^2} = (1+x)^{-2}\). Using the binomial series expansion, we expand \((1+x)^{-2}\) as \(\sum_{n=0}^{\infty} (-1)^n C_{2+n-1}^{n} x^n\), where \(C_{k}^{n}\) represents the binomial coefficient.

Therefore, the power series representation for \(f(x)\) is \(f(x) = \sum_{n=0}^{\infty} (-1)^n C_{2+n-1}^{n} x^n\).

Step-by-step explanation:

(a) The function rule for Big Wave Waterpark, f(x) = 2.5x + 5. where f(x) is total cost and x is number of slides ridden.

b) The function rule for Coaster City is, f(x) = 5x + 7.50, where x is the number of roller coaster ridden and f(x) is total cost.

c) The function rule for Virtual Reality Lan is, f(x) = 3x + 10, where f(x) is total cost and x is the number reality rides ridden.

(a) Let f(x) = ax +b be the function which represents the total cost of Big Wave Park where x represents the number of taken ride.

We can see that f(2) = 10; f(4) = 15 and f(6) = 20.

Therefore, 2a + b = 10 and 4a + b = 15

So, 2(2a + b) - (4a + b) = 2*10 - 15

4a + 2b - 4a - b = 20 - 15

b = 5

Now, f(6) = 20

6a + b = 20

6a + 5 = 20 [putting the value of 'b']

6a = 20 - 5 = 15

a = 15/6 = 5/2 = 2.5

Hence, the function rule for Big Wave Waterpark is, f(x) = 2.5x + 5.

(b) The function rule for Coaster city is, f(x) = 5x + 7.50, where x is the number of roller coaster ridden.

(c) Let the total cost for Virtual Reality Lan is, f(x) = cx + d, where x is the number reality rides ridden.

From the given graph we can see that, f(10) = 40; f(20) = 70; f(30) = 100.

So, 10c + d= 40 ........... (i)

20c + d = 70 ............... (ii)

Solving (i) and (ii) we get,

2(10c + d) - (20c + d) = 2*40 - 70

20c + 2d - 20c - d = 80 - 70

d = 10

So putting the value d = 10 in f(30) = 100 we get,

30c + 10 = 100

30c = 100 - 10 = 90

c = 90/30 = 3

So the function rule is, f(x) = 3x + 10.

To find the marginal cost of producing the 20th item, we need to calculate the derivative of the cost function with respect to the quantity (q) and evaluate it at q = 20.

Given the cost function C(q) = 500 + 3q², we differentiate it with respect to q:

C'(q) = d/dq (500 + 3q²)

      = 6q

Now, we can evaluate the derivative at q = 20:

C'(20) = 6(20)

      = 120

Therefore, the marginal cost of producing the 20th item is $120.

Interpretation:

The marginal cost represents the additional cost incurred when producing one additional unit.

In this case, the marginal cost of $120 for the 20th item means that if the production level is increased from 19 units to 20 units, the cost of production will increase by about $120.
