Answer:

the experimental probability that the next vase produced at the factory will be chipped is 1/5.

Step-by-step explanation:

Since 5 out of the 13 boats that docked were from North Carolina, the experimental probability of the next boat being from North Carolina is the number of favorable outcomes (i.e., the number of boats from North Carolina) divided by the total number of outcomes (i.e., the total number of boats that docked).

Therefore, the experimental probability that the next boat to dock will be from North Carolina is:

P(North Carolina) = 5/13

For the second question:

Since 2 out of the last 10 vases produced were chipped, the experimental probability that the next vase will be chipped is:

P(chipped) = 2/10 = 1/5

Therefore, the experimental probability that the next vase produced at the factory will be chipped is 1/5.

Answer:

Option D.

Step-by-step explanation:

Domain and range of inverse function:

The domain of the inverse function(x values) is the range(y values) of the original function.

The range of the interse function(y values) is the domain of the original function(x values).

Original function:

Domain: \(x \geq 0\)

Range: \(y \leq -1\)

Inverse function:

x values in the domain of the inverse function are the y values in the range of the original function. So

Domain: \(x \leq 1\)

Same for range(exchange of y and x).

Range: \(y \geq 0\)

Step-by-step explanation:

for it to be a right triangle, a² + b² = c². C must be the larger of the 3 sides, which in this case is 18. if you substitute 8 for a and 15 for b, you do not get C = 18, meaning that this is not a right triangle

Answer: 3x - 2 + 7x - 6 + x, 46°, 118°, 16° in that order

Step-by-step explanation:

We know that the sum of the angles in a triangle is 180° so we can write the equation

(3x - 2) + (7x + 6) + x = 180

3x + 7x + x - 2 + 6 = 180

11x + 4 = 180

11x + 4 - 4 = 180 - 4

11x = 176

x = 176 ÷ 11 = 16 meaning that angle N = x = 16°

From here we can work out angle L = 3x - 2 = 3 × 16 - 2 = 48 - 2 = 46°

And angle M = 7x + 6 = 7 × 16 + 6 = 118°

Example: (2x - 4) x=7 so (2x (x=7) - 4) =18

The relation shown in the table is not a function.

A function is a process or set of instructions that takes inputs, performs a specific task, and produces an output. Functions are key components of programming languages, allowing the coder to create complex commands with simple instructions. For example, a function can be used to add two numbers together or to generate a random number. Functions can also be combined to create more complex sequences of instructions.

This is because for the input of x = 9, there are two corresponding outputs of y, namely 6 and 4. This does not satisfy the definition of a function, which states that for any given input, there must be only one output. Therefore, the relation shown in the table is not a function.

Answer:

240 events

Step-by-step explanation:

Given that:

Mean = 4 events per minute

The mean number of events per hour :

Number of Events per minute * (number of minutes per hour)

Number of minutes per hour = 60

Hence, mean number of events per hour :

4 * 60 = 240

Match the change in the position of the minute hand with the angle made by the change.

π/3 → The minute hand moves from 4 to 6.

2π/3 → The minute hand moves from 3 to 7.

5π/6 → The minute hand moves from 5 to 10.

7π/6 → The minute hand moves from 2 to 9.

Answer:

to the nearest whole number, we get:

dd/dt ≈ 490 miles per hour

Step-by-step explanation:

Let's call the distance between the plane and the radar station "d". We want to find the rate at which this distance is increasing when the total distance between the plane and the station is 5 miles.

We can use the Pythagorean theorem to relate the distance d to the altitude h of the plane:

d^2 = h^2 + x^2

where x is the horizontal distance the plane has traveled from directly above the station.

Taking the derivative of both sides with respect to time t, we get:

2d * dd/dt = 2h * dh/dt + 2x * dx/dt

where dd/dt is the rate at which the distance between the plane and the station is changing, and dh/dt and dx/dt are the rates at which the altitude and horizontal distance are changing, respectively.

At the moment when the plane is 5 miles away from the station, we have:

d = 5 miles

h = 1 mile (since the plane is flying at an altitude of 1 mile)

dx/dt = 480 mi/h (since the plane is flying horizontally at a speed of 480 mi/h)

We want to find dd/dt, the rate at which the distance between the plane and the station is increasing. We can solve for dd/dt by plugging in the given values and solving for it:

2d * dd/dt = 2h * dh/dt + 2x * dx/dt

2(5 miles) * dd/dt = 2(1 mile) * 0 + 2x * (480 mi/h)

10 * dd/dt = 960 * x

We still need to find x, the horizontal distance traveled by the plane when it is 5 miles away from the station. We can use the Pythagorean theorem again:

d^2 = h^2 + x^2

(5 miles)^2 = (1 mile)^2 + x^2

x^2 = (5 miles)^2 - (1 mile)^2

x = √(24 miles^2)

x = 4.899 miles (rounded to three decimal places)

Now we can plug in the value of x and solve for dd/dt:

10 * dd/dt = 960 * x

10 * dd/dt = 960 * 4.899

dd/dt = 489.9 (rounded = 490)

Answer:

they all passed away so they went back to GRU and he burried them and at their f l e s h, The rest all ran away.

1. Jada's data set has a mean of 5, Diego's data set has a mean of 6, and Lin's data set has a mean of 4.

2. The data set that has the greatest variability is Lin's data set because it has the highest standard deviation of 3.6.

In Mathematics and Geometry, the mean for this set of data can be calculated by using the following formula:

Mean = [F(x)]/n

Question 1.

In this scenario and exercise, we would determine the mean of the three data sets based on the number of text messages sent by Jada, and Diego, and Lin over 6 days as follows;

Mean number of text for Jada = (4 + 4 + 4 + 6 + 6 + 6)/6

Mean number of text for Jada = 30/6

Mean number of text for Jada = 5.

Mean number of text for Diego = (4 + 5 + 5 + 6 + 8 + 8)/6

Mean number of text for Diego = 36/6

Mean number of text for Diego = 6.

Mean number of text for Lin = (1 + 1 + 2 + 2 + 9 + 9)/6

Mean number of text for Lin = 24/6

Mean number of text for Lin = 4.

Question 2.

In Statistics, variability is a measure of the spread of a data set. Also, we would use standard deviation to determine the variability in each data set as follows;

Standard deviation = √(1/n × ∑(xi - u₁)²)

Standard deviation for Jada = √(1/6 × [(4 - 5)² + (4 - 5)² + (4 - 5)² + (6 - 5)² + (6 - 5)² + (6 - 5)²]

Standard deviation for Jada = √(6/6) = 1

Standard deviation for Diego = √(1/6 × [(4 - 6)² + (5 - 6)² + (5 - 6)² + (6 - 6)² + (8 - 6)² + (8 - 6)²]

Standard deviation for Diego = √(14/6) = 1.53

Standard deviation for Lin = √(1/6 × [(1 - 4)² + (1 - 4)² + (2 - 4)² + (2 - 4)² + (9 - 4)² + (9 - 4)²]

Standard deviation for Lin = √(76/6) = 3.6

4. Ronnie increased the amount of money in his piggy bank by 25%. Which expression can be used to find the amount of money in his bank? Let "m" represent the original​.

Step-by-step explanation:

let original price = p

a) p+ 0.3p = p + 30% of p

30% more than original price

b) 0.7p = 70% of p

= 70% of the original price

c) 17p = 17 × p

= 17times of the original price

d) p-0.7p = p - 70% of p

= 70% less than original price

Let original time = t

e) 85% more than the original time = t + 85%of t

= t + 0.85t

f) 15% less time than the original time = t - 15% of t

= t - 0.15t

g) 85% time decrease = t - 85% of t

= t - 0.85t

h) 15% time increase = t + 15% of t

= t + 0.15t

4. Since "m" represent the original amount in Hus piggy bank

An increase of 25% = original amount + 25% of original amount

= m + 25% of m

'Of' means multiplication

I don't know how helpful I'll be, sorry :(

Step-by-step explanation:

So the scale factor is 1/4 reduction because the triangle P'Q'R' is smaller than the original. When reflecting the triangle P'Q'R' over the Y axis, you'll have P"Q"R". The graphing might be a little confusing but it's just a vertical reflection.

P" = (-1,0)

Q"= (0,-1)

R"= (2,-1)

Triangles PQR and P"Q"R" are not congruent because P"Q"R" has had a 1/4 reduction and a vertical reflection.

Answer:

Y=KX so its 10=K2

Step-by-step explanation:

Plug in the Number OR K=y/x

we would expect m to be positive.

In this case, we're considering a formula of the form y = mx + b, where y represents the cost of a four-year college x years after 2010. The variable m represents the coefficient of x, which determines the slope of the line.

Since we're discussing the cost of college, it's reasonable to expect that it generally increases over time. Therefore, we would expect the coefficient m to be positive. A positive value of m indicates that as the number of years after 2010 increases (x), the cost of college (y) will also increase.

If m were negative, it would imply a decreasing cost over time, which is less likely for a four-year college. If m were zero, it would indicate that the cost remains constant regardless of the number of years after 2010, which is also unlikely given the rising trend in college costs.

Step-by-step explanation:

\( \frac{ - 10 + r}{2} \geqslant - 13\)

multiply both sides by 2:

\( - 10 + r \geqslant - 26\)

add 10 on both sides:

\(r \geqslant - 16\)

Answer:

\(r \ge -16\)

Step-by-step explanation:

To solve any equation/inequality:

1. get the variable to show up exactly once

2. isolate it

\(\frac{-10+r}{2} \ge -13\)

Multiply both sides by 2 and simplify (note that we're multiplying by a positive, not a negative, so the direction of the inequality stays the same, whereas multiplying or dividing by a negative would have changed the direction of the inequality)

\(\frac{-10+r}{2} *2 \ge -13 *2\)

\(-10+r \ge -26\)

Add 10 to both sides, and simplify

\((-10+r)+10 \ge (-26)+10\)
