Answer:

A.) $10,400

Contribution every payday = $60

Pay periods in a year = 26

Step-by-step explanation:

Assume her salary, that is total cost = y

Percentage deduction 15% of total cost

biweekly paychecks = $60

Therefore, 15% of y = $60

(15/100)y = 60

15y = 6000

y = 400

Total value of contribution:

$400 × number of biweeks in a year

If number of weeks in a year = 52

the correct option is D: reviewing secondary data.

Nearly every research project should begin by reviewing secondary data. Secondary data refers to data that was collected by someone else or data that has already been published in journals or books.

What is a research project?

A research project is a systematic study carried out to investigate or find out new information or to answer questions. It is a scientific method used to collect data, analyze the data, and interpret it to arrive at a conclusion.

What is secondary data?

Secondary data is data that was previously gathered and studied by others, rather than the data that was collected from the original source. It is the data that is already available in journals, books, and other resources.

Secondary data is important in research because it helps researchers to validate their findings and improve their accuracy.

So, reviewing secondary data is the first and foremost thing that researchers should do before starting any research project because it can save a lot of time and money, and it can help to identify gaps in existing knowledge.

Answer:

f. 85

Step-by-step explanation:

All triangles add up to 180 degrees

BCE=25

then you need to find DBC, you can do that since ABD is isocilies that means all sides are equal in length and angle so 180 divided by 3 (number of side) is 60

isoceles triangle have 2 sides that are equiangular, cince we know BCA is 25 we also know BAC is 25, leaving angle ABC to be 130 (180-50=130)

we subtract angle ABD from angle ABC to get angle DBC, leaving angle DBC to equal 70 degrees

since 70 (angle DBC) + 25 (Angel BCA)= 95

we just subtrract 95 from 180 to get the answer 85 (:

Answer:

85 degrees

Step-by-step explanation:

if Δ ABD is equilateral  then the 3 sides and three angles are equal

sum of angles of Δ=180

180/3=60 degrees (∠A,∠B,∠D)

ΔBCA is isosceles then the two angles A and C are equal = 25

∠B=180-50=130

∠B in Δ BEC=130-60=70

∠E+∠B+∠C in Δ BEC=180

∠E= 180-70-25=85 degrees

Using geometric sequences, 20,480 rabbits are grown during the 12th month.

A geometric sequence is a sequence of numbers in which each term after the first is found by multiplying the preceding term by a fixed non-zero number called the common ratio.

At the end of the first month, there are 10 x 2 = 20 rabbits.

At the end of the second month, there are 20 x 2 = 40 rabbits.

Similarly, at the end of the third month, there are 40 x 2 = 80 rabbits.

This is a geometric sequence with a common ratio of 2 and a first term of 10. The number of rabbits at the end of the 12th month would be:

10 x 2^12 = 10 x 4096 = 40,960 rabbits

To find the number of rabbits grown during the 12th month, we need to subtract the number of rabbits at the end of the 11th month from the number of rabbits at the end of the 12th month:

\(40,960 - (10 x 2^{11}) = 40,960 - 20,480 = 20,480\)

Hence, 20,480 rabbits are grown during the 12th month.

Step-by-step explanation:

To find F^-1(x), we need to solve for x in terms of f(x) using the given equation for f(x):

f(x) = 4(3x+2)

First, we can simplify the expression inside the parentheses:

f(x) = 12x + 8

Next, we can solve for x by isolating it on one side of the equation:

f(x) - 8 = 12x

(x is isolated)

x = (f(x) - 8) / 12

Therefore, F^-1(x) = (x - 8) / 12.

The Gram-Schmidt process was applied to the vectors [-6, -3, -6], [3, 3, 0], and [-7, -2, -1], resulting in the orthogonal vectors [-0.577, -0.289, -0.577], [0.526, 0.526, -0.667], and [-0.648, 0.729, -0.220].

To perform the Gram-Schmidt process on the given sequence of vectors, let's denote the vectors as v1, v2, and v3

v1 = [-6, -3, -6]

v2 = [3, 3, 0]

v3 = [-7, -2, -1]

Set the first orthogonal vector, u1, equal to the normalized v1:

u1 = v1 / ||v1||

Find the projection of v2 onto u1:

proj_v2_u1 = (v2 ⋅ u1) * u1

where ⋅ represents the dot product.

Find the orthogonal vector v2_orthogonal by subtracting the projection from v2:

v2_orthogonal = v2 - proj_v2_u1

Set the second orthogonal vector, u2, equal to the normalized v2_orthogonal:

u2 = v2_orthogonal / ||v2_orthogonal||

Find the projection of v3 onto u1 and u2:

proj_v3_u1 = (v3 ⋅ u1) * u1

proj_v3_u2 = (v3 ⋅ u2) * u2

Find the orthogonal vector v3_orthogonal by subtracting the projections from v3:

v3_orthogonal = v3 - proj_v3_u1 - proj_v3_u2

Set the third orthogonal vector, u3, equal to the normalized v3_orthogonal:

u3 = v3_orthogonal / ||v3_orthogonal||

The resulting orthogonal vectors u1, u2, and u3 will form an orthonormal basis. Remember to normalize the vectors by dividing by their respective norms (||v||) at each step.

Performing the calculations, the orthogonal vectors are:

u1 = [-0.577, -0.289, -0.577]

u2 = [0.526, 0.526, -0.667]

u3 = [-0.648, 0.729, -0.220]

The mean, median, and sample variance of the given dataset are:Mean = 23.17Median = 21Sample variance = 173.5592

(a) Mean The mean (or average) of a dataset is calculated by summing up all the values and dividing by the total number of values.

The formula for calculating the mean is: `mean = (sum of values) / (total number of values)`For the given dataset, we have:20, 50, 22, 14, 23, 10

Sum of values = 20 + 50 + 22 + 14 + 23 + 10 = 139

Total number of values = 6Therefore, the mean is given by: `mean = 139 / 6 = 23.17`Answer: 23.17 (rounded to two decimal places)

(b) Median To find the median, we need to arrange the dataset in increasing order:10, 14, 20, 22, 23, 50The median is the middle value of the dataset. If there are an odd number of values, the median is the middle value. If there are an even number of values, the median is the average of the two middle values. Here, we have 6 values, so the median is the average of the two middle values: `median = (20 + 22) / 2 = 21` Answer: 21(e)

Sample variance s²The sample variance is calculated by finding the mean of the squared differences between each value and the mean of the dataset.

The formula for calculating the sample variance is: `s² = ∑(x - mean)² / (n - 1)`where `∑` means "sum of", `x` is each individual value in the dataset, `mean` is the mean of the dataset, and `n` is the total number of values.For the given dataset, we have already calculated the mean to be 23.17.

Now, we need to calculate the squared differences between each value and the mean:

20 - 23.17 = -3.1722 - 23.17

= -1.170 - 23.17

= -13 - 23.17

= -9.1723 - 23.17

= -0.1710 - 23.17

= -13.17

The sum of the squared differences is given by:

∑(x - mean)² = (-3.17)² + (-1.17)² + (-13.17)² + (-9.17)² + (-0.17)² + (-13.17)²

= 867.7959

Therefore, the sample variance is given by: `s² = 867.7959 / (6 - 1) = 173.5592`Answer: 173.5592 (rounded to four decimal places)

The mean, median, and sample variance of the given dataset are:Mean = 23.17Median = 21Sample variance = 173.5592

The power series ∑n=0[infinity]n!x2n converges for all real values of x. This can be shown using the ratio test, where the limit as n approaches infinity of |(n+1)!x^(2n+2)/(n!x^(2n))| is equal to the limit as n approaches infinity of |(n+1)x^2|, which equals infinity for x≠0.

However, the ratio test is inconclusive for x=0, so we need to use a different test to determine convergence at x=0. The Cauchy-Hadamard theorem states that the radius of convergence of a power series is given by R=1/lim sup (|an|^(1/n)), where an is the nth term of the series.

Applying this to our power series, we get R=1/lim sup (n!^(1/n) x^2), which simplifies to R=0 for all values of x. Therefore, the power series converges only at x=0 and diverges for all other real values of x.

Therefore, the probability that the selected tick is also a carrier of Lyme disease, given that it carries HGE, is approximately 0.999 or 99.9%.

To find the probability that the selected tick is also a carrier of Lyme disease given that it carries HGE, we can use the concept of conditional probability.

Let's define the following events:

A: The tick carries Lyme disease

B: The tick carries HGE

We are given:

P(A) = 0.18 (probability of a tick carrying Lyme disease)

P(B) = 0.07 (probability of a tick carrying HGE)

P(A ∩ B) = 0.07 (probability of a tick carrying both Lyme disease and HGE)

The probability we want to find is P(A|B), the probability of the tick carrying Lyme disease given that it carries HGE.

We can use Bayes' theorem to calculate this:

P(A|B) = (P(B|A) * P(A)) / P(B)

P(B|A) represents the probability of a tick carrying HGE given that it carries Lyme disease. We are not given this information directly, so we need to calculate it.

P(B|A) = P(A ∩ B) / P(A)

= 0.07 / 0.18

= 0.3889

P(A|B) = (0.3889 * 0.18) / 0.07

We cannot claim that the newsletter publisher's statement is incorrect. Hence, the conclusion is uncertain.

The newsletter publisher's claim is uncertain after performing a test at the 0.02 level of significance as the testing firm fails to reject the null hypothesis.

In this case, we cannot claim that the publisher's statement is incorrect without additional tests and proof. Here is an explanation of the above statement.

A hypothesis test is conducted to find out whether or not there is sufficient evidence to contradict a hypothesis. In this case, the hypothesis test's null hypothesis claims that the newsletter publisher's statement is correct.

The alternate hypothesis claims that the newsletter publisher's claim is incorrect. As a result, the null hypothesis is represented by \(H_0\):

p = 0.71 (71%) and

the alternate hypothesis is represented by \(H_a\):

p ≠ 0.71 (71%).

Where 'p' denotes the percentage of newsletter readers who own a Rolls Royce.

The test statistic for a sample proportion can be calculated by

z = (p - P) / √(P(1 - P) / n)

Where 'p' denotes the sample proportion,

P denotes the population proportion, and

n denotes the sample size.

A two-tailed test is used because the alternate hypothesis is written as \(H_a\):

p ≠ 0.71 (71%).

At a 0.02 significance level, the test statistic's critical value is ±2.58 (round off) Because the test statistic does not fall in the rejection region, we fail to reject the null hypothesis.
