From the given data which shows the length of fish in a pond, there is an outlier at 7.

Hence, the correct option is B.

To determine if the data contains any outliers, we can use the interquartile range (IQR) method. First, we need to find the median and the quartiles of the data set

Arrange the data in order 7, 9, 11, 13, 15, 15, 19, 28.

Median (Q2) = the middle value = 15.

Q1 (the first quartile) = the median of the lower half of the data set = 9.

Q3 (the third quartile) = the median of the upper half of the data set = 19.

Next, we can calculate the IQR as the difference between the third and first quartiles

IQR = Q3 - Q1 = 19 - 9 = 10.

Finally, we can identify any outliers as values that are more than 1.5 times the IQR above the third quartile or below the first quartile.

The upper outlier bound is Q3 + 1.5 x IQR = 19 + 1.5 x 10 = 34.

The lower outlier bound is Q1 - 1.5 x IQR = 9 - 1.5 x 10 = -6.

Since the minimum value in the data set is 7, which is greater than the lower outlier bound, we have an outlier at 7. The maximum value in the data set is 28, which is less than the upper outlier bound, so it is not an outlier.

Hence, the correct option is B.

Answer:

a) Her reasoning is wrong because √50 does not simplify to 2√25, it simplifies to 5√2. With her thinking that √50 simplifies to 2√25, then this leads to her doing 2 * 5 which equals 10.

b) To estimate a square root, you have to find two square numbers that make the number lie in between the two squares. In this case we need to find two square numbers where one square number is smaller than 50 and the other one is bigger. You should have found the two square numbers to be 7 and 8 because 7² = 49 and 8² = 64. Now we divide 50 by either number, either 7 or 8. As we can't use a calculator it is easier to divide 50 by 8 than 7. 50/8 = 6.25 Now we find the average of 6.25 and 8 which is 14.25/2 = 7.125 7.125 rounded to the nearest tenth is 7.1 Therefore the answer for b is 7.1

Answer:

(a) √50 is not equal to 10.

√50 = √25√2 = 5√2

(b) √50 = 5√2 = 5(1.41) = 7.05 = 7.1

(a) The standard deviation of the required distribution for vitamin C is approximately 7.98 mg/d.
(B) The plot should show a bell-shaped curve centered at 60 mg/d, with the RDA located slightly to the right of the center.

(a) To determine the standard deviation of the required distribution for vitamin C, we can use the information provided about the estimated average requirement (EAR) and the recommended dietary allowance (RDA). The EAR is the mean of the distribution (60 mg/d), and the RDA (75 mg/d) is assumed to be the 97.72 percentile.

We can use the Z-score formula to find the standard deviation:

Z = (X - μ) / σ

Where Z is the Z-score, X is the value of the RDA, μ is the mean (EAR), and σ is the standard deviation.

First, find the Z-score corresponding to the 97.72 percentile. Using a standard normal table or calculator, we find that Z ≈ 2.0.

Now, plug in the values into the Z-score formula:

2.0 = (75 - 60) / σ
σ = (75 - 60) / 2.0
σ = 15 / 2.0
σ = 7.5 mg/d
Plugging in the values, we get:
1.88 = (75 - 60) / σ

Solving for σ, we get:
σ = (75 - 60) / 1.88 = 7.98

The standard deviation of the required distribution is 7.5 mg/d.

(b) To sketch the distribution of vitamin C requirements for 19- to 30-year-old women, follow these steps:

1. Draw a normal distribution curve.
2. Mark the mean (EAR) at 60 mg/d on the horizontal axis.
3. Mark the RDA at 75 mg/d and the UL at 2000 mg/d on the horizontal axis.
4. Indicate that the standard deviation is 7.5 mg/d.

The distribution of vitamin C requirements for 19- to 30-year-old women is Normal, with a mean of 60 mg/d and a standard deviation of 7.98 mg/d. The EAR, RDA, and UL can be marked on the plot as follows:

- EAR: 60 mg/d, located at the center of the distribution
- RDA: 75 mg/d, located at the 97.72 percentile of the distribution
- UL: 2000 mg/d, located at the far right end of the distribution (beyond the range of the plot)

The probability that Lola pulled a red marble first and a yellow marble second is 0.134 or approximately 13.4%.

To calculate the probability that Lola pulls a red marble first and a yellow marble second, we can use the formula:

P(Red, Yellow) = P(Red) x P(Yellow|Red)

where P(Red) is the probability of pulling a red marble first, and P(Yellow|Red) is the conditional probability of pulling a yellow marble second given that a red marble was pulled first.

First, we can calculate P(Red):

P(Red) = number of red marbles / total number of marbles

P(Red) = 4 / (4 + 4 + 12)

P(Red) = 4 / 20

P(Red) = 0.2

So the probability of pulling a red marble first is 0.2.

Next, we can calculate P(Yellow|Red):

P(Yellow|Red) = number of yellow marbles remaining / total number of remaining marbles

P(Yellow|Red) = 12 / (4 + 3 + 11)

P(Yellow|Red) = 12 / 18

P(Yellow|Red) = 0.67

So the probability of pulling a yellow marble second given that a red marble was pulled first is 0.67

Now we can use the formula:

P(Red, Yellow) = P(Red) x P(Yellow|Red)

P(Red, Yellow) = 0.2 x 0.67

P(Red, Yellow) = 0.134

The sum of the convergent geometric series is 5/4, or 1.25. The given infinite geometric series is 1, 1/5, 1/25, 1/125, ...

To determine if this series is convergent or divergent, we need to examine the common ratio (r) between each term. The common ratio can be calculated by dividing a term by its previous term. For example, (1/5) / 1 = 1/5, (1/25) / (1/5) = 1/5, and so on. Thus, the common ratio (r) is 1/5.

A geometric series converges if the absolute value of its common ratio is less than 1 (i.e., |r| < 1). In this case, since |1/5| < 1, the series is convergent.

To find the sum of the convergent geometric series, we use the formula:

S = a / (1 - r)

where S is the sum of the series, a is the first term, and r is the common ratio.

Here, a = 1 and r = 1/5. Plugging these values into the formula, we get:

S = 1 / (1 - (1/5))

S = 1 / (4/5)

S = 5/4

Thus, the sum of the convergent geometric series is 5/4, or 1.25.

The orthonormal basis for V is: {v1 = 1/√(2), v2 = (t - √(2)/2)/√(2), v3 = (√(3)/2)t^2 - (√(6)/2)t}. To produce an orthonormal basis for V, we need to find a set of vectors that are linearly independent and can span the space V. Since we are working with polynomials of degree less than 2, we can write them in the form:

p(t) = at^2 + bt + c

where a, b, and c are real coefficients.

To find the basis, we can start with the standard basis for V, which is {1, t, t^2}. We can then use the Gram-Schmidt process to produce an orthonormal basis.

Here are the steps:

1. Normalize the first vector in the basis, which is 1, to obtain:

v1 = 1/√(2)

2. Calculate the projection of t onto v1 and subtract it from t to obtain the second vector in the basis:

v2 = (t - (t, v1)v1)/∥(t - (t, v1)v1)∥

where (t, v1) is the inner product of t and v1.

Simplifying, we get:

v2 = (t - √(2)/2)/√(2)

3. Finally, calculate the projection of t^2 onto v1 and v2, and subtract these projections from t^2 to obtain the third vector in the basis:

v3 = (t^2 - (t^2, v1)v1 - (t^2, v2)v2)/∥(t^2 - (t^2, v1)v1 - (t^2, v2)v2)∥

where (t^2, v1) and (t^2, v2) are the inner products of t^2 with v1 and v2, respectively.

Simplifying, we get:

v3 = (√(3)/2)t^2 - (√(6)/2)t

Therefore, the orthonormal basis for V is:

{v1 = 1/√(2), v2 = (t - √(2)/2)/√(2), v3 = (√(3)/2)t^2 - (√(6)/2)t}

Answer: Option B ($1200 at 8% compound interest per annum for 2 years) is a better investment.

Step-by-step explanation:

In option A, the interest is calculated on the principal amount only, which is known as simple interest.

Simple Interest Formula:

Simple Interest = (P × R × T) / 100

Where P is the principal amount, R is the rate of interest and T is the time period.

So, for option A:

P = $1200

R = 9%

T = 2 years

Simple Interest = (1200 × 9 × 2) / 100 = $216

Total Amount = Principal + Simple Interest = $1200 + $216 = $1416

In option B, the interest is calculated on the principal amount as well as the interest earned in previous years, which is known as compound interest.

Compound Interest Formula:

Total Amount = P (1 + R/100) ^n

Where P is the principal amount, R is the rate of interest and n is the number of years.

So, for option B:

P = $1200

R = 8%

n = 2 years

Total Amount = 1200 (1 + 8/100) ^2 = $1369.86

As we can see, option B yields a higher total amount compared to option A, so it is a better investment choice.

To calculate the probability that the resulting product is even, we need to first determine the total number of possible outcomes. There are 90 two-digit numbers ranging from 10 to 99. If we choose two different numbers, there are a total of 90C2 (90 choose 2) possible combinations, which is equal to 4,005.

To calculate the number of even products, we need to consider the different scenarios. If one of the numbers is even, the product will also be even. There are 45 even numbers in the range from 10 to 99, so the number of even products that can be formed from an even number and an odd number is 45 x 45 = 2025.

If both numbers are odd, then the product will also be odd, and hence not even. There are 45 odd numbers in the range from 10 to 99, so the number of odd products that can be formed from an odd number and an odd number is 45 x 44 = 1980.

Therefore, the total number of even products that can be formed is 2025. The probability that the resulting product is even is then 2025/4005, which simplifies to 9/17, or approximately 0.5294. So, there is a 52.94% chance that the resulting product will be even.

The closest that the family will come to the waterfall while on the road is 5.6 miles.

To solve this problem, we can use the law of cosines. Let x be the distance that the family travels from the point where the bearing is S71E to the point where the bearing is S35E, and let d be the distance from the family's starting point to the waterfall.
We have:
cos(71) = d/x
cos(35) = d/(x+8)
Multiplying both sides of the first equation by x and both sides of the second equation by (x+8), we get:
d = x cos(71)
d = (x+8) cos(35)
Setting the right-hand sides of these equations equal to each other and solving for x, we get:
x cos(71) = (x+8) cos(35)
x = 8 cos(35)/(cos(71)-cos(35))
Plugging this into the first equation above, we get:
d = x cos(71) = 8 cos(35) cos(71)/(cos(71)-cos(35))
This gives us the distance from the family's starting point to the waterfall. To find the closest distance that the family will come to the waterfall while on the road, we need to subtract the radius of the waterfall from this distance. Let's assume that the radius of the waterfall is 50 feet.
The closest distance that the family will come to the waterfall while on the road is:
d - 50 = 8 cos(35) cos(71)/(cos(71)-cos(35)) - 50
This is approximately equal to 5.6 miles. Therefore, the closest that the family will come to the waterfall while on the road is 5.6 miles.

When long radishes (SLSL) are crossed to oval radishes (SLSR), the F1 generation will all have the genotype SLSR because they inherit one allele for long shape from one parent and one allele for oval shape from the other parent. When the F1 generation is allowed to cross at random among themselves, the expected phenotypic ratio in the F2 generation will be 1:2:1 for long:round: oval.

This is because each F1 individual can produce gametes with either the S allele or the L allele, and the S allele is dominant over the L allele for determining shape.

So, when two F1 individuals with the SLSR genotype cross, there are four possible offspring genotypes: SSLR (long), SLSR (long), SRSR (round), and SLSL (oval). The probability of each genotype is 1/4. However, since the S allele is dominant over the L allele, both the SSLR and SLSR genotypes will express the long-shape phenotype. Thus, the phenotypic ratio in the F2 generation will be 1 long: 2 round: 1 oval.

In summary, when long radishes are crossed to oval radishes and the F1 generation is allowed to cross at random among themselves, the expected phenotypic ratio in the F2 generation will be 1 long : 2 round : 1 oval.

db/dt = 40/12 = 10/3 Feet per second, or approximately 3.33 feet per second. So the foot of the ladder is being pulled away from the wall at a rate of about 3.33 feet per second when it is 8 feet away from the wall and the top of the ladder is sliding down at 4 feet per second.

We can use the Pythagorean theorem to relate the length of the ladder, the distance of its foot from the wall, and the height it reaches on the wall:

[tex]a^2 + b^2 = c^2[/tex]

where c is the length of the ladder, a is the distance of its foot from the wall, and b is the height it reaches on the wall. Differentiating with respect to time, we get:

2a da/dt + 2b db/dt = 2c dc/dt

We are interested in finding db/dt when a = 8 feet and dc/dt = -4 feet per second (negative because the top of the ladder is sliding down). We also know that c = 10 feet, so we can plug in these values and solve for db/dt:

2(8) da/dt + 2b db/dt = 2(10) (-4)

Simplifying:

16 da/dt + b db/dt = -40

We also know that when a = 8 feet and b = 6 feet (from the Pythagorean theorem), the ladder is at a height of 6 feet on the wall. Therefore, we can plug in these values and solve for da/dt:

8 da/dt + 6 db/dt = 0

Simplifying:

da/dt = -(3/4) db/dt

Now we can substitute this expression for da/dt in the first equation, and solve for db/dt:

The expected loss without the generator ($495,000) is less than the cost of installing the generator ($800,000), it would not be economically justifiable for the bank to install the new power generator based on this decision tree analysis.

The management of First American Bank faces a decision regarding the installation of an emergency power generator to mitigate potential losses from physical catastrophes such as power failures or fires.

To evaluate this decision, we can use decision tree analysis.

Without the generator, there is a 10% chance of a power outage. In the event of an outage, there is a 0.05 probability of very large losses ($80 million) and a 0.95 probability of slight losses ($1 million). To calculate the expected loss from not installing the generator, we can use the following formula:

Expected loss = (probability of outage) x [(probability of large loss x large loss amount) + (probability of slight loss x slight loss amount)]

Expected loss = 0.1 x [(0.05 x $80 million) + (0.95 x $1 million)]
Expected loss = 0.1 x [$4 million + $950,000]
Expected loss = 0.1 x $4.95 million
Expected loss = $495,000

Now let's compare this expected loss to the cost of installing the emergency power generator, which is $800,000. Since the expected loss without the generator ($495,000) is less than the cost of installing the generator ($800,000), it would not be economically justifiable for the bank to install the new power generator based on this decision tree analysis.
