Answer: In the figure AB is about 8.4 inches and AC is about 13.05 inches.

Step-by-step explanation: We can use cosine to find the hypotenuse. \(cos(40)=\frac{10}{x} \\cos(40) (x)=\frac{10}{x}(x)\\cos(40) (x) =10\\\frac{cos(40) (x)}{cos (40)} =\frac{10}{cos (40)} \\x=\frac{10}{cos(40)}\)

Using a calculator x is about 13.05

Using tangent we can find the length opposite of <C

\(tan(40)=\frac{x}{10} \\tan(40) (10)=\frac{x}{10}(10)\\tan(40) (10) = x\)

Using a calculator x would be about 8.4

About \(80.5\%\) of the variation in y can be attributed to the linear relationship with x.

Used the concept of correlation coefficient that states,

The proportion of the variation in y that can be explained by the linear relationship between x and y can be determined by squaring the correlation coefficient

Given that,

When paired variables are considered, the linear correlation coefficient is,

\(r=0.897\)

Hence the proportion of the variation in y explained by x is,

\(r^2 = (0.897)^2\)

\(r^2 = 0.804609\)

This means that about \(80.5\%\) of the variation in y can be attributed to the linear relationship with x.

The probability comes out to be 9/32.

Deducing Arrival Time Possibility

All the possible arrival times by Alice and Bob, in minutes after 5 PM, is constrained by the values of given values of x and y,

x = 0, y = 0, x = 60, y = 60.

Here, let the values of x represent how many minutes after 5 PM Alice arrives at the party.

Let the y values represent the time in minutes that Bob arrives at the party after 5 PM.

Calculating the Required Probability

The times that concern us, however, are obtained by the following probability function,

x + y ≤ 45.

And x = 0, y = 0, and x + y ≤ 45 define the constraints of this probability function. Thus the perimeter of such a graph will be given as,

(45² / 2) = 1012.5 square units

Since the total area of the various arrival times is 60 x 60, or 3600 square units, the probability that Alice and Bob will arrive together after 5 o'clock in the evening in less than 45 minutes is therefore = 1012.5 / 3600 = 9/32

The slope of the line with points (-1/2 ,-1/2) and (-3,-4) is 1.4

A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.

The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.  

Therefore,

m =  y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.

Be aware that tan ∅ = y/x

We also refer to this tan as the line's slope

We know that slope, slope = m = \(\frac{y_2 - y_1}{x_2 - x_1}\)

For the pairs of points (-1/2 ,-1/2) and (-3,-4)

⇒ m = \(\frac{-4- (-1/2)}{-3 - (-1/2)}\)

⇒ m = \(\frac{-7/2}{-5/2 }\)

⇒ m = 7/5

⇒ m = 1.4

Hence, the slope of the line with points (-1/2 ,-1/2) and (-3,-4) is 1.4

To find the value(s) of k such that the function is continuous at x = -1, we need to equate the two pieces of the function at x = -1 and ensure that the limit of the function approaches the same value from both sides.

Let's evaluate the function at x = -1:

For x < -1, the function is f(x) = ln(2x + 5), so at x = -1, we have f(-1) = ln(2(-1) + 5) = ln(3).

For x ≥ -1, the function is f(x) = 8x - k, so at x = -1, we have f(-1) = 8(-1) - k = -8 - k.

For the function to be continuous at x = -1, the values of ln(3) and -8 - k should be equal. Therefore, we can set up the equation:

ln(3) = -8 - k.

Solving this equation for k, we have:

k = -8 - ln(3).

Hence, the value of k that makes the function continuous at x = -1 is k = -8 - ln(3).

In summary, the value of k that ensures the function is continuous at x = -1 is k = -8 - ln(3).

50 mg be the expected mass of the sample in the year 2002, to the nearest whole number

In 1990, a sample of a radioactive isotope had an initial mass of 110 mg and decayed exponentially over time.

A measurement in 1993 revealed that the sample's mass had decayed to 90

110 mg - 90 mg = 20 mg (amount decayed in the 3 total years)

20 mg ÷ 3 years = 6.6 mg decayed per year

Complete question:

Factor the given expression to simplest form to the simplest form

\(\mathrm{\sqrt{49x^2} }\)

The vector A is (49.9m) x and vector B is (1.5m) x.

In the given question, A − B = (−51.4m)x, C =(62.2m)x, and A +B +C =(13.8m)x.

Find the vector A. Find the vector B.

We may disregard the vector x and treat the issue as an arithmetic one since all of the measurements are in the same direction (simultaneous equations).

A − B = −51.4.............................(1)

C = 62.2.............................(2)

A + B + C = 13.8.............................(3)

Now putting the value of C from Equation (2) in Equation (3)

A + B + C = 13.8

A + B + 62.2 = 13.8

Subtract 62.2 on both side, we get

A + B = 13.8 - 62.2

A + B = - 48.4.....................(4)

Adding the equation (1) and (4), we get

2A = - 99.8

Divide by 2 on both side, we get

A = - 49.9

Now subtracting the equation (1) and (4), we get

2B = -48.4 - ( -51.4)

2B = 3

Divide by 2 on both side, we get

B = 1.5

Since all of the calculations are done in terms of the unit vector x.

So the answer is vector B = (1.5m) x and vector A = (49.9m) x.

To determine the number of green ladders that should be produced to net a profit of $155, we need to consider the given constraints and objectives.

The company must ship at least 215 ladders per day to satisfy the contract with the store. Let's denote the number of blue ladders produced per day as "B" and the number of green ladders produced per day as "G". Based on the demand requirements, we have the following inequalities:

B ≥ 100 (demand for blue ladders)

G ≥ 70 (demand for green ladders)

To satisfy the cost limitations, we have:

B ≤ 160 (maximum blue ladders production)

G ≤ 150 (maximum green ladders production)

The total number of ladders produced per day is B + G, and we want this to be at least 215. Now, let's consider the profit calculation. Each blue ladder results in a $5 profit, while each green ladder results in a $3 loss. The total profit can be calculated as 5B - 3G.

To net a profit of $155, we set up the equation:

5B - 3G = 155

We need to find the value of G that satisfies all the constraints and gives us the desired profit. This involves solving the system of inequalities and the equation simultaneously. Unfortunately, without specific values for the production quantities or additional constraints, it is not possible to provide a numerical solution. The solution would require applying linear programming techniques to find the feasible region and optimize the profit.

One car travel South at 64 mi/h and the other travels west at 48 mi/h. The distance between the cars increases with rate at 80 mi/h.

To find the rate of change, we need to find the derivative of the variables with respect to time.

Let:

p = distance between 2 cars

q = distance between car 1 and the start point

r = distance between car 2 and the start point

Using the Pythagorean Theorem:

p² = q² + r²

Take the derivative with respect to time:

2p dp/dt = 2q dq/dt + 2r dr/dt

dq/dt = speed of car 1 = 64 mi/h

dr/dt = speed of car 2 = 48 mi/h

The distance of car 1 and car 2 from the start point after 4 hours:

q = 64 x 4 = 256 miles

r = 48 x 4 = 192 miles

Using the Pythagorean theorem:

p² =256² + 192²

p = 320 miles

Hence,

2p dp/dt = 2q dq/dt + 2r dr/dt

p dp/dt = q dq/dt + r dr/dt

320  x dp/dt = 256 x 64 + 192  x 48

Based on the given confidence interval, the null hypotheses (c) and (d) can be rejected at the 5% significance level.

To determine which null hypothesis can be rejected at the 5% significance level, we need to compare it with the confidence interval.

The 99% confidence interval (9, 15) means that we are 99% confident that the true population mean falls between 9 and 15.

At the 5% significance level, we reject a null hypothesis when the hypothesized value falls outside the confidence interval.

Let's analyze each option:

(a) The population mean is less than or equal to 15.

Since the upper bound of the confidence interval is 15, this null hypothesis cannot be rejected.

(b) The population mean is greater than or equal to 9.

Since the lower bound of the confidence interval is 9, this null hypothesis cannot be rejected.

(c) The population mean is greater than or equal to 15.

Since the lower bound of the confidence interval is 9, which is less than 15, this null hypothesis can be rejected.

(d) The population mean is 12.

Since the null hypothesis specifies a specific value (12), and the confidence interval (9, 15) does not include 12, this null hypothesis can be rejected.

The purpose of random sampling is to select a set of items from a population such that the sample description accurately represents the population.

Random sampling is a type of sampling in which the researcher randomly selects a subset of participants from a population. Each member of the population has an equal chance of being selected. Data is then collected from as high a percentage of this random subset as possible. Simple random sampling selects a smaller group (sample) from a larger group of the total number of participants (population).

Samples are at the heart of survey research. It is often called the population microcosm, and the process of drawing a sample should maximize the similarity of the sample to the population under study. Sampling is therefore the selection of a set of elements from a population whose description accurately describes the parameters of the total population from which the sample is selected.
