Step-by-step explanation:

Based on the provided percentages, the probability that a randomly selected person is a Democrat is 90%.

The probability that a randomly selected person is a Democrat can be calculated using the given information. Since 24% of the USA population is Catholic and 68% of Catholics are Democrats, while 98% of non-Catholics are Democrats, the overall probability of being a Democrat can be computed as the weighted average of these probabilities.

Let's assume there is a total population of 100 people for ease of calculation. Given that 24% of the population is Catholic, there are 24 Catholics and 76 non-Catholics.

Out of the 24 Catholics, 68% are Democrats, which amounts to approximately 16 Catholics who are Democrats.

For the non-Catholics, 98% are Democrats, which corresponds to approximately 74 non-Catholics who are Democrats.

Adding up the number of Catholics and non-Catholics who are Democrats gives a total of 16 + 74 = 90 people out of 100 who are Democrats.

Therefore, the probability that a randomly selected person is a Democrat is 90/100, which simplifies to 0.9 or 90%.

Hence, based on the provided percentages, the probability that a randomly selected person is a Democrat is 90%.

a. 12 deg, b. 168 deg

We can create a systems of equations using this information, since supplement angles add up to 180 deg and complementary angles add up to 90 deg, when angle = x deg and supplement = y deg,

x + y = 180

y = 2(90 - x ) + 12

Solving:

x + 2(90 - x) + 12 = 180

-x + 180 + 12 = 180

x = 12

12 + y = 180

y = 168

The equity in the house after three years is $30,000.

Equity in a house is the difference between the current market value of the house and the outstanding mortgage balance (if any). Since the problem does not mention any outstanding mortgage balance, we can assume that the entire purchase price of $250,000 was paid upfront.

Therefore, the equity in the house after three years is:

$280,000 (current market value) - $250,000 (original purchase price) = $30,000

So, you have $30,000 equity in the house after three years.

The steps Alana used to solve the equation x - 7 = 18 are:

Step 1: Add 7 to both sides to isolate x: x - 7 + 7 = 18 + 7.

Step 2: Simplify and solve for x: x = 25.

Alana used the following steps to solve the equation x - 7 = 18:

Step 1: Add 7 to both sides to isolate x: The reason for adding 7 to both sides is to eliminate the constant term (-7) from the left-hand side of the equation and to move it to the right-hand side. By doing so, Alana isolates the variable term (x) on the left-hand side and obtains x = 18 + 7.

Step 2: Simplify and solve for x: The reason for simplifying the right-hand side of the equation is to obtain the value of x that makes the equation true. By adding 18 and 7, Alana gets 25, which is the solution to the equation.

In summary, Alana used the addition property of equality to add the same value to both sides of the equation, in order to isolate the variable term and solve for x.

If Drew completes 11 laps around the circular track with a diameter of approximately 1/4 mile, he runs approximately 8.635 miles.

The distance that Drew runs can be calculated using the formula: distance = circumference x number of laps. The circumference of a circle can be found by multiplying its diameter by pi (π), which is approximately equal to 3.14.

Given that the diameter of the track is approximately 1/4 mile, its radius is 1/8 mile (since the radius is half of the diameter). Therefore, the circumference of the track is 2 x pi x 1/8 mile, which simplifies to pi/4 mile or approximately 0.785 miles.

To find the distance Drew runs in 11 laps, we simply multiply the circumference of the track by 11.

distance = 0.785 miles/lap x 11 laps

The correct statement regarding the null hypothesis is: the null hypothesis claims the opposite of what the researcher believes.

The null hypothesis is the claim that no relationship exists between two sets of data or variables being analyzed. The

null hypothesis is that any experimentally observed difference is due to chance alone, and an underlying causative

relationship does not exist, hence the term "null".

In research, the null hypothesis is a statement of no effect or no relationship between variables, while the alternative

hypothesis represents the effect or relationship the researcher is interested in demonstrating.

The purpose of statistical testing is to determine whether there is enough evidence to reject the null hypothesis in

The magnitude of the acceleration is approximately -0.267 m/s², and the car does not hit the deer.

To find the magnitude of acceleration, we need to consider the forces acting on the car. The gravitational force component parallel to the incline is given by \(\( F_g = m \cdot g \cdot \sin(10^\circ) \)\), where \(\( m \)\) is the mass of the car and \(\( g \)\) is the acceleration due to gravity. The frictional force opposing the motion is given by \(\( F_f = m \cdot g \cdot \cos(10^\circ) \cdot \mu_k \)\), where \(\( \mu_k \)\) is the coefficient of kinetic friction.

The net force acting on the car is the difference between the gravitational force and the frictional force: \(\( F_{\text{net}} = F_g - F_f \)\).

Using Newton's second law, \(\( F_{\text{net}} = m \cdot a \)\), where \(\( a \)\) is the acceleration. We can solve for \(\( a \)\) by rearranging the equation: \(\( a = \frac{F_{\text{net}}}{m} \)\).

Substituting the given values and calculating the magnitude of acceleration:

\(\[ a = \frac{m \cdot g \cdot \sin(10^\circ) - m \cdot g \cdot \cos(10^\circ) \cdot \mu_k}{m} \\\)

\(\quad = g \cdot (\sin(10^\circ) - \cos(10^\circ) \cdot \mu_k) \]\)

Now, let's calculate the value of the acceleration. We are given that the speed of the car is 25 mph, which is equivalent to \(\( 25 \times \frac{1609}{3600} \)\) m/s.

Using \(\( g = 9.8 \, \text{m/s}^2 \)\) and \(\( \mu_k = 0.4 \)\), we have:

\(\[ a = 9.8 \cdot (\sin(10^\circ) - \cos(10^\circ) \cdot 0.4) \approx -0.267 \, \text{m/s}^2 \]\)

The negative sign indicates that the acceleration is in the opposite direction of the car's motion.

To determine if the car hits the deer, we need to compare the stopping distance of the car to the distance to the deer. The stopping distance can be calculated using the equation: \(\( d = \frac{v^2}{2 \cdot a} \)\), where \(\( v \)\) is the initial velocity and \(\( a \)\) is the acceleration.

Substituting the given values, we have:

\(\[ d = \frac{(25 \times \frac{1609}{3600})^2}{2 \cdot (-0.267)} \approx 596 \, \text{m} \]\)

Since the stopping distance (596 m) is greater than the distance to the deer (25 m), the car does not hit the deer.

Therefore, the magnitude of acceleration is approximately \(\( -0.267 \, \text{m/s}^2 \)\) and the car does not hit the deer.

Answer:

<y = 110 degrees

<x = 70 degrees

Step-by-step explanation:

Hi, I am not gonna do this on paper, but I will try and explain it well.

70 degrees and <y are supplementary angles, which means the sum of their measurments adds up to 180 degrees. Therefore, 180-70 gives us <y

So, <y = 110 degrees.

Then, to find <x, we know the angle opposite it is 70 degrees, so it too is 70 degrees (I forgot the theorem for this but it exists lol)

therefore,

<y = 110 degrees

<x = 70 degrees

Step-by-step explanation:

There are two points that satisfy the system of equations:

(0.79, 0.37)

(-3.79, -12.37)

The system of equations is:

y = 3x - 3

y = -x^2

To determine which point from a specified set satisfies the system of equations, we need to find the values of x and y that satisfy both equations simultaneously.

Substituting y = 3x - 3 into the second equation, we get:

3x - 3 = -x^2

Rearranging this equation, we get:

x^2 + 3x - 3 = 0

Using the quadratic formula, we can solve for x:

x = (-3 ± sqrt(3^2 - 41(-3))) / (2*1) = (-3 ± sqrt(21)) / 2

Therefore, there are two possible values of x that satisfy the system of equations:

x = (-3 + sqrt(21)) / 2 ≈ 0.79

x = (-3 - sqrt(21)) / 2 ≈ -3.79

To find the corresponding values of y, we can substitute these values of x into either equation. For example, if we use y = 3x - 3, we get:

y ≈ 0.37 (when x ≈ 0.79)

y ≈ -12.37 (when x ≈ -3.79)

Therefore, there are two points that satisfy the system of equations:

Answer:

The first transit on one side of the trench is 18 ft higher than the other side of the trench. The transit is set at 4.5 above ground, therefore the transit lens is 18' + 4.5' = 22.5' above the location on the other side of the trench. The angle of depression is the angle formed by the horizontal and the line of sight to the other side and it is given as 31°. This forms a right angle triangle with height of 22.5' and an interior angle of 31°, Then

tan( 31°) = Height / base, with the base representing the width of the trench

base = Height / tan(31°) = 22.5' / tan(31°) = 37.45' is the width of the trench

Answer:

So the trench is 37.5 feet wide

Step-by-step explanation:

The trench with telescope is 18 feet higher than the other.

The height of telescope is 4.5 feet.

Total height = 18 + 4.5 = 22.5

Now, we can see in the figure that the distances between telescope and the opposite trench, the height and width makes a right angled triangle.

So, perpendicular = total height = 22.5

base = wideness of the trench

We know,

Tan 31 = p/b

tan 31 = 22.5/b

b = 22.5 / 0.6

a) The probability of randomly selecting 4 males out of 7 spectators, given that 70% of the spectators are males, can be calculated using the binomial probability formula.

b) To find the probability that at most 5 of the randomly selected spectators are females, we need to calculate the cumulative probability of selecting 0, 1, 2, 3, 4, and 5 females from the total number of selected spectators.

a) To calculate the probability of selecting 4 males out of 7 spectators, we can use the binomial probability formula:

P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

Where:

- n is the total number of trials (number of people selected)

- k is the number of successful trials (number of males selected)

- p is the probability of success in a single trial (probability of selecting a male)

- C(n, k) is the binomial coefficient, calculated as C(n, k) = n! / (k! * (n - k)!)

In this case, n = 7, k = 4, and p = 0.70 (probability of selecting a male). Therefore, the probability of selecting 4 males out of 7 spectators is:

P(X = 4) = C(7, 4) * (0.70)^4 * (1 - 0.70)^(7 - 4)

b) To find the probability that at most 5 of the selected spectators are females, we need to calculate the cumulative probability of selecting 0, 1, 2, 3, 4, and 5 females. This can be done by summing the individual probabilities for each case.

P(X ≤ 5 females) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)

To calculate each individual probability, we use the same binomial probability formula as in part a), with p = 0.30 (probability of selecting a female).

Finally, we sum up the probabilities for each case to find the probability that at most 5 of the selected spectators are females.
