After a particularly bad forearm break, a person loses motor function and feeling in their 4th and 5th phalanges, along with the side of the hand directly above these fingers. Which nerve(s) has/have been damaged

Answer:

$24

Step-by-step explanation:

Original price of blouse = $18

Discounted price of blouse = 3/4 x 18 = $13.50

Discounted blouse + discounted skirt = $31.50

⇒  13.50 + discounted skirt = 31.50

⇒  discounted skirt = 31.50 - 13.50 = 18

Let S be the original price of the skirt.

If the discounted skirt is 3/4 of it's original price, then

$18 = (3/4) S

S = 18 ÷ 3/4 = 24

Therefore, the original price of the skirt is $24

The null hypothesis was not refuted. There is insufficient evidence to support the assertion that male commute times are considerably longer than female commute times (P-value=0.155).

The data is:

Males n1 = 237

M1 = 31.6

s1 = 24.0

Females n2 = 263

M2 = 29.3

s2 = 24.3

This is a hypothesis test for a population mean differences.

According to the assertion, the average daily travel time for men is much longer than the average daily commuting time for women.

The null and alternative hypotheses are then:

\(H_{0}\) = \(\mu_m\) - \(\mu_f\) = 0

\(H_{a}\) = \(\mu_m\) - \(\mu_f\) > 0

The threshold of significance is set at 0.05.

The mean of Sample 1 (males) is 31.6, with a standard deviation of 24.

Sample 2 (females) does have a mean of 29.3 and a standard deviation of 24.3 (n2 = 263).

Md = 2.3 is the difference in sample means.

\(M_{d}\) = \(M_{m}\) - \(M_{f}\)

\(M_{d}\) = 31.6 - 29.3

\(M_{d}\) = 2.3

The formula to calculate the estimated standard error of the difference between the means:

\(S_{Md}\) = √(((σ1)² ÷ (n1)² + ((σ2)² ÷ (n2)²)

\(S_{Md}\) = √((24)² ÷ (237)²) + (24.3)² ÷ (263)²))

\(S_{Md}\) = √(0.0102 + 0.0085)

\(S_{Md}\) = 0.136

the t-statistic as,

t = ((\(M_{d}\) - ( \(\mu_m\) - \(\mu_f\) )) ÷ \(S_{Md}\))

t = ((2.3 - 0) ÷ 0.136)

t = 1.611

The degrees of freedom for this test are:

df = n1 + n2 - 1 = 237 + 263 - 1

df = n1 + n2 - 1 = 499

Because this is a right-tailed test with 499 degrees of freedom and t = 1.611, the P-value is determined as follows (using a t-table):

P - value = P(t > 1.611) = 0.155

The impact is not significant since the P-value (0.155) is greater than the significance threshold (0.05).

As a result, the null hypothesis was not rejected.

The statement is False

First understood what is correlation  & what is regression ?

Correlation :When measuring the relationship between two continuous variables, such as a dependent and independent variable or between two independent variables, correlation analysis is used.

Regression :Assessing the link between the outcome variable and one or more factors is referred to as regression analysis. Risk factors and co-founders are referred to as predictors or independent variables, whilst the result variable is known as the dependent or response variable. In a regression analysis, the dependent variable is represented by "y" and the independent variables are represented by "x."

Regression and correlation have some distinct differences.

The quantity and strength of the relationship between two variables is displayed through correlation. The data points are not connected by a fixed line. To determine how much one variable changes when the other stays constant, you compute a correlation. When r is zero, there is no relationship. One variable increases as the other does when r is positive. One variable rises while the other falls when r is negative.

While correlation does not match a line, linear regression identifies the optimal line that can predict y from x.

When measuring both variables, correlation is employed, whereas linear regression is typically used when manipulating the variable x.

Why the given statement is false ?

The statement is  False because correlation does not imply causation. This means if X and Y are correlated we cannot conclude if X is response or explanatory or Y is response or explanatory...hence no clearly identification of which is explanatory or response is needed

The toll of death per day in 2015 is 91.

We are given the approximate number of people who died in year 2015, which is 33,200. Now, as per the known fact, the year 2015 has 365 days. So, we can easily calculate the toll in deaths per day by performing division.

Number of deaths in 365 days = 33,200

Number of deaths each day = 33,200 ÷ 365

Performing division to find the number of deaths per day

Number of deaths each day = 90.96

Rounding off the digits to find number of deaths each day

Number of deaths each day = 91

Hence, this toll in deaths per day is 91.

What is exponent?

Exponent denotes how many times a number is multiplied by itself.

If the probability of having a defect is 20%, then the probability that there is no defect is 0.8 or 80%.

The probability that there is no defect can be calculated by subtracting the probability of having a defect from 1. Since the probability of having a defect is 20%, the probability of no defect is:

1 - 0.20 = 0.80

Therefore, the probability that there is no defect is 80%.

In probability theory, the complement rule states that the probability of an event occurring is equal to 1 minus the probability of its complement. In this case, the event of interest is having no defect, and its complement is having a defect.

If the probability of having a defect is 20%, it means that out of every 100 cases, 20 cases would have a defect. Hence, the remaining 80 cases would not have a defect. This means that the probability of no defect is 80% or 0.80.

By subtracting the probability of having a defect (20%) from 1, we obtain the probability of no defect (80%). This is because the sum of the probabilities of mutually exclusive events must be equal to 1. Therefore, the probability that there is no defect is 80%.

if the population standard deviation is increased while the sample size is 28, the confidence interval will become wider. This is because there is more variability in the sample mean, and therefore more uncertainty in the estimate of the population parameter.

If the sample size is 28 and the population standard deviation is increased, there will be a direct impact on the confidence interval. This is because the confidence interval is calculated based on the sample mean and the standard deviation. If the population standard deviation is increased, it means that there is more variability in the population. This increase in variability will lead to wider confidence intervals.
A confidence interval is a range of values that is likely to contain the true population parameter with a certain level of confidence. The width of the confidence interval is determined by the sample size, the standard deviation, and the level of confidence.
In this case, if the population standard deviation is increased, it means that the sample standard deviation will also increase. The sample mean will be relatively more variable than it would be if the population standard deviation was lower. This increase in variability will cause the confidence interval to become wider, as there is more uncertainty in the estimate of the population parameter.
In summary, if the population standard deviation is increased while the sample size is 28, the confidence interval will become wider. This is because there is more variability in the sample mean, and therefore more uncertainty in the estimate of the population parameter. It is important to note that increasing the sample size can help to reduce the impact of increased population standard deviation on the confidence interval, as a larger sample size provides more accurate estimates of the population parameter.

To evaluate the definite integral of f(g(4)) - f(g(2)), we need to consider the composition of functions and the Fundamental Theorem of Calculus.

Let's break down the steps to find the definite integral: Evaluate g(4) and g(2) using the function g. Substitute the values of g(4) and g(2) into the function f. Find the antiderivative of f(g(x)) with respect to x, denoted as F(g(x)). Apply the Fundamental Theorem of Calculus, which states that the definite integral of F'(x) from a to b is equal to F(b) - F(a), where F'(x) is the derivative of F(x).

Evaluate F(g(4)) - F(g(2)) using the antiderivative F(g(x)). Note that the expression F(g(4)) - F(g(2)) represents the change in the antiderivative F(g(x)) over the interval from g(2) to g(4). Therefore, the definite integral for f(g(4)) - f(g(2)) is F(g(4)) - F(g(2)).

The algebraic representation that shows a dilation that is an enlargement is (5/2 x,5/2 y). (Option D)

A dilation is a type of transformation that changes the size of the shape or object.  It refers to a process of changing an object’s size by decreasing or increasing its dimensions by a scaling factor. A dilation produces an image that has the same shape as the original image but is a different size.

A dilation that results in a larger image is called an enlargement while a dilation that generates a smaller image is called a reduction. A dilation is described using the scale factor and the center of the dilation (which is a fixed point in the plane).

For a scale factor > 1, the image is an enlargement; for a scale factor < 1 and  > 0, the image is a reduction; and for a scale factor = 1, the figure and the image are congruent. Hence, for a point (x,y), algebraic representation that shows a dilation that is an enlargement is (5/2 x,5/2 y) as the scale factor is greater than 1. For the remaining options, the scale factor is between 0 and 1, hence they are reduction.

By observing the pattern and using the given information, we calculated that Jane would put 28 pennies in the sixth row if she continues the pattern of placing pennies. However, there seems to be a discrepancy between the information given and the pattern. It is advisable to verify the accuracy of the provided information to ensure the correct calculation of the number of pennies in each row.

We can observe that each row follows a specific pattern. The number of pennies in each row increases by 3 more than the previous row.

To find the number of pennies in the sixth row, we can use the formula:

Number of pennies in the nth row = Number of pennies in the (n-1)th row + 3

Let's calculate the number of pennies in each row using this formula:

First row: 4 pennies

Second row: 4 + 3 = 7 pennies

Third row: 7 + 3 = 10 pennies

Fourth row: 10 + 3 = 13 pennies

Fifth row: 13 + 3 = 16 pennies

Sixth row: 16 + 3 = 19 pennies

However, the prompt stated that Jane put 13 pennies in the third row, not 10 pennies. This suggests that there might be an error in the given information. Assuming the given information is correct, let's continue the calculation:

Seventh row: 13 + 3 = 16 pennies

Eighth row: 16 + 3 = 19 pennies

Ninth row: 19 + 3 = 22 pennies

Tenth row: 22 + 3 = 25 pennies

Step 1: Initial velocity (u) = 39.0 m/s Initial displacement (s) = -403 m (because he is moving in the downward direction)Acceleration (a) = 9.8 m/s² (due to gravity)

Step 2: We can use the formula for displacement: `s = ut + (1/2)at²`Where t is the time taken.

Step 3: Substituting the given values of u, s, and a, we get:-403 = 39t + (1/2) × 9.8 × t²-403 = 39t + 4.9t²

Step 4: We have a quadratic equation now, let's solve it.4.9t² + 39t - 403 = 0Using the quadratic formula: `t = (-b ± sqrt(b² - 4ac)) / 2a`Where a = 4.9, b = 39, and c = -403

Step 5: Solving the above equation, we get two values oft = 7.14 s and t = -9.32 s As time cannot be negative, we reject the negative value of t.So, Iron Man will take 7.14 seconds to reach the ground.

Step 6: Now, let's calculate the distance traveled by Iron Man to reach the ground.`s = ut + (1/2)at²` (from step 2)`s = 39 × 7.14 + (1/2) × 9.8 × 7.14²`= 273.12 meters.

We are given that f(x) = √x, and we want to find the equation of the tangent line to this function at x = 81. We can use the formula for the equation of the tangent line:

y - f(a) = f'(a)(x - a),

where f'(a) is the derivative of f(x) evaluated at x = a.

First, we calculate the derivative of f(x) as:

f'(x) = 1/(2√x)

Evaluated at x = 81, we get:

f'(81) = 1/(2√81) = 1/18

So the equation of the tangent line to f(x) at x = 81 is:

y - √81 = (1/18)(x - 81)

Simplifying:

y - 9 = (1/18)x - (1/2)

y = (1/18)x + 8.5

Now we can use this equation to approximate √81.1:

√81.1 ≈ (1/18)(81.1) + 8.5

≈ 9.0139

Therefore, using linear approximation with the tangent line, we can approximate √81.1 as 9.0139.

Step-by-step explanation:

-4x - 2y = 18

The dimensions of the field that will allow for the maximum area are 200 meters by 400/3 meters

From the question, we have

Fencing available, Perimeter = 1600 meters

Number of sections, n = 3

Represent the dimensions with x and y

So, we have:

Area = Number of sections* x * y = 3xy

Perimeter = (Number of sections * 2x + 2(Number of sections) * y) = 6x + 4y

Recall that

Perimeter = 1600 meters

So, we have

6x + 4y = 1600

A = 3xy

Divide 6x + 4y = 1600 by 2

3x + 2y = 800

Make y the subject

y = (800 - 3x)/2

Substitute y = (800 - 3x)/2 in A = 3xy

A = 3x(800 - 3x)/2

So, we have

A = 1200x - 4.5x²

Differentiate and set to 0

1200 - 9x = 0

So, we have

9x = 1200

Divide by 9

x = 400/3

Recall that y = (800 - 3x)/2

So, we have

y = (800 - 3 x 400/3)/2

y = 200
