The stopping distance for a car traveling at 55 mph is 60,500 feet.

The equation to solve this problem would look like the following

s = v²/k

The stopping distance s will increase (varies directly) as the velocity increases.

Putting in the values we know

45 = 30²/k

⇒ k = 45/900

⇒ k = 0.05

Now,

at 55 mph we would have

    s = 55²/0.05

⇒ s = 3025/0.05

⇒ s = 60,500

s = 60,500 feet to stop

Complete Question:

The stopping distance s of a car varies directly as the square of its speed v. If a car traveling at 30 mph requires 45ft to stop, find the stopping distance for a car traveling at 55 mph.

Answer: Random Sampling

Step-by-step explanation:

The act of collecting data that are representative of the population data is called random sampling.

Answer:

The unit rate is 2 feet per year

Step-by-step explanation:

The graph is missing (See attachment)

To determine the unit growth;

First, we have to pick any two corresponding on the x and y axis

When x = 5; y = 10

When x = 1; y = 2

These can be represented as;

\((x_1,y_1) = (5,10)\)

\((x_2,y_2) = (1,2)\)

Next, is to determine the slope using;

\(m = \frac{y_2 - y_1}{x_2 - x_1}\)

Substitute values for x and y

\(m = \frac{2 - 10}{1 - 5}\)

\(m = \frac{-8}{-4}\)

\(m = 2\)

Hence, the unit rate is 2 feet per year

For a measurement of 7.84 cm, 8 digit is the estimated digit

In the decimal system, each digit in a number represents a place value based on its position relative to the decimal point.

The digit to the left of the decimal point represents the units place, and each subsequent digit to the right represents a smaller unit, such as tenths, hundredths, and so on.

The digit to the right of the decimal point that is not zero is known as the estimated digit.

In the given measurement of 7.84 cm, the digit to the left of the decimal point is 7, which represents the units place.

The digit to the right of the decimal point is 8, which represents the tenths place. Since the digit in the hundredths place is 4 and not zero, the digit in the tenths place (i.e., 8) is the estimated digit.

This means that the measurement of 7.84 cm is accurate to the nearest tenth of a centimeter, and the digit 8 is the estimated digit.

Answer:

L=2.5

Step-by-step explanation:

P=2l+2w

The function given has the variables p, l, and w.

p = perimeter = 35

l = length = ?

w = width = 15

substitute the given values into the function.

p = 2l + 2w

35 = 2l + 2(15)

35 = 2l + 30

Subtract 30 from both sides of function.

5 = 2l

Divide both sides of the function by 2.

2.5 = l

The length is 2.5 feet.

The Taylor series for f(x)=ex about x=2 is given by ∑n=0[infinity]cn(x−2)n where cn = fⁿ(2)/n! = e²/2! e²/3! ... e²/n!.

The Taylor series is a way to represent a function as an infinite sum of terms that involve the function's derivatives evaluated at a specific point.

In this case, we want to find the Taylor series for f(x)=ex about x=2. To do this, we first need to find the derivatives of f(x) at x=2.

We have fⁿ(x) = ex for all n, so fⁿ(2) = e² for all n. We can then use this to find the coefficients cn in the Taylor series.

We have cn = fⁿ(2)/n! = e²/2! e²/3! ... e²/n!.

We can then substitute these coefficients into the Taylor series to get ∑n=0[infinity]cn(x−2)n = ∑n=0[infinity] e²/2! e²/3! ... e²/n!(x−2)n, which is the Taylor series for f(x)=ex about x=2.

Given:

A figure in which a transversal line t intersect the two parallel lines a and b.

To find:

The measure of the numbered angles.

Solution:

If a transversal line intersect the two parallel lines, then

1. Corresponding angles are equal.

2. Alternate interior angles are equal.

3. Alternate exterior angles are equal.

Now,

\(m\angle 1+99^\circ=180^\circ\)              (Linear pair)

\(m\angle 1=180^\circ-99^\circ\)

\(m\angle 1=81^\circ\)

\(m\angle 2=99^\circ\)                         (Vertically opposite angles)

\(m\angle 3=\angle 1=81^\circ\)                (Vertically opposite angles)

\(m\angle 4=99^\circ\)                         (Corresponding angles)

\(m\angle 5=\angle 3=81^\circ\)                (Alternate interior angles)

\(m\angle 6=99^\circ\)                         (Alternate exterior angles)

Answer:

(17,25)

Step-by-step explanation:

To find the solution to the system, solve with elimination.

Equation 1.

−4x + 3y =7

Equation 2.

5x − 2y =35

To cancel out the y-variable, multiply the first equation by 2, and the second equation by 3.

2(−4x + 3y =7)

-8x+6y=14

3(5x − 2y =35)

15x-6y=105

Combine both equations.

-8x+6y=14

15x-6y=105

7x=119

x= 17

Plug in x into the first equation to solve for y.

-8x+6y=14

-8(17)+6y=14

-136+6y=14

6y=150

y=25

In ANOVA, if the observed F equals or exceeds the critical F, the experimental outcome is considered statistically significant.

Analysis of Variance (ANOVA) is a statistical method used to compare the means of two or more groups. The F-statistic is the test statistic used in ANOVA. When conducting an ANOVA test, we compare the observed F-value to the critical F-value to determine the significance of the results.

Step 1: Calculate the observed F-value using the given data.

Step 2: Determine the critical F-value using the F-distribution table, taking into account the degrees of freedom and the desired significance level (usually set at 0.05).

Step 3: Compare the observed F-value to the critical F-value.

If the observed F-value equals or exceeds the critical F-value, it indicates that there is a statistically significant difference between the group means, and we reject the null hypothesis. In other words, the experimental outcome suggests that at least one of the group means is significantly different from the others.

since r is so widely used, it is appropriate to calculate r for nonlinear data: False.

The calculation of r (Pearson's correlation coefficient) is based on the assumption that the relationship between the two variables is linear. Therefore, it is not appropriate to calculate r for nonlinear data as it may give misleading results.

In summary, it is not appropriate to calculate r for nonlinear data as it assumes a linear relationship between the variables. Other methods such as Spearman's rank correlation or Kendall's tau may be used for nonlinear data.


n: The correlation coefficient 'r' is specifically designed to measure the strength and direction of a linear relationship between two variables. While it is widely used, calculating 'r' for nonlinear data is not appropriate, as it will not accurately capture the true nature of the relationship between the variables.

When dealing with nonlinear data, it is better to use other statistical methods designed for such data, rather than relying on the correlation coefficient 'r'.

Check the picture below.

Answer:

Step-by-step explanation:

Let "a number" be x.

"3/7 of a number" means (3/7)x

"32 less" means - 32

Thus, "32 less than 3/7 of a number" means (3/7)x -32

"is 11/35 of that number" means = (11/35)x

Put these together and we get:

(3/7)x -32 = (11/35)x

(3/7)x - (11/35)x = 32   Rearrang to get the x on one side

We need to change "(3/7)x - (11/35)" so that the two terms have a common denominator.

If we multiply the first term by (5/5) [which is equal to 1], we get:  

(5/5)(3/7)x or

(15/35)x

We can now write:

(15/35)x - (11/35)x = 32

(4/35)x = 32

Multiply both sides by (35/4)

(35/4)(4/35)x = (35/4)(32)

x = (35)(8)

The weight distribution of newborn African lions may not necessarily follow a normal distribution, and the actual percentages can vary based on the specific data available.

To determine the percentage of newborn African lions that weigh less than 3 pounds and the percentage that weigh more than 3.8 pounds, we would need statistical data on the weight distribution of newborn African lions. Since we don't have that information, we cannot provide the exact percentages.

However, if we assume that the weights of newborn African lions follow a normal distribution, we can use the properties of the standard normal distribution to make an estimation.

For the percentage of newborn African lions weighing less than 3 pounds:

We would need to know the mean and standard deviation of the weight distribution to calculate the Z-score for a weight of 3 pounds and then find the corresponding percentage using a standard normal distribution table. Without this information, we cannot provide an accurate estimation.

For the percentage of newborn African lions weighing more than 3.8 pounds:

Similarly, we would need the mean and standard deviation of the weight distribution to calculate the Z-score for a weight of 3.8 pounds and find the corresponding percentage using a standard normal distribution table. Without the required information, we cannot provide a specific estimation.

Please note that the weight distribution of newborn African lions may not necessarily follow a normal distribution, and the actual percentages can vary based on the specific data available.

The slope of the line that divides the region bounded by the parabola \(y=5x-3x^2\)and the x-axis into two regions with equal area is 5.

To find the slope of the line that divides the region into two equal areas, we need to determine the point of intersection between the parabola and the x-axis. Since the line passes through the origin, its equation will be y = mx, where m represents the slope.

Setting the equation of the parabola equal to zero, we find the x-values where the parabola intersects the x-axis. By solving the equation\(5x - 3x^2 = 0\), we get x = 0 and x = 5/3.

To divide the region into two equal areas, the line must pass through the midpoint between these x-values, which is x = 5/6. Plugging this value into the equation of the line, we have y = (5/6)m.

Since the areas on both sides of the line need to be equal, we can set up an equation using definite integrals. By integrating the equation of the parabola from 0 to 5/6 and setting it equal to the integral of the line from 0 to 5/6, we can solve for m. After performing the integration, we find that m = 5.

Therefore, the slope of the line that divides the region into two equal areas is 5.
