We may state that the slope of the function y = 5x + 4 is hence 5.

A function in mathematics is a relationship between two sets of numbers in which each member in the first set (known as the domain) corresponds to a unique element in the second set (called the range). A function, in other words, takes inputs from one set and creates outputs from another. The variable x is frequently used to represent the inputs, and the variable y is used to represent the outputs. An equation or a graph can be used to describe a function. For example, the equation y = 2x + 1 depicts a linear function in which each value of x gives a unique value of y.

y = 5x + 4 is the given function.

This is written in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

When we compare the provided function to the slope-intercept form, we see that the slope is 5.

The slope of the function y = 5x + 4 is hence 5.

Since none of the 13 classmates had been given math homework between the original survey and Kelly's second survey, the sum of the values in the second data set is the same as the sum of the values in the original data set. Therefore, the change in the means can be determined without calculating the mean of either data set by considering the number of data points in each set.

Since both data sets have the same number of data points, the change in the means will be zero. This is because the mean is calculated by dividing the sum of the values by the number of data points, and since the sum of the values is the same in both data sets, the means will also be the same.

In other words, if the mean of the first data set is x, then the sum of the values in the first data set is 13x (since there are 13 classmates), and the sum of the values in the second data set is also 13x (since none of the values have changed). Therefore, the mean of the second data set will also be x, and the change in the means will be zero.

The probability that their first child will have kidney disease is 1/8.

What is probability?

The proportion of favorable cases to all possible cases is used to determine how likely an event is to occur.

Here, we have

Both parents must be heterozygous to have a 1/4 chance of having an

affected child. Parent 2 is heterozygous (her father was homozygous recessive, but she has unaffected).

For the child to have the disease, both Parent 1 and Parent 2 would need to be heterozygous

There is a 50% chance of this for Parent 1 and a 100% chance of this for Parent 2 and then, there is a 25% chance that their first child will be affected:

50%× 100% × 25% = 12.5%

1/2 × 1/4 = 1/8

Hence, the probability that their first child will have kidney disease is 1/8.

The given trigonometric identity (cosθ − sinθ)/(cosθ + sinθ) = (1 − tanθ)/(1 + tanθ) has been proved.

In the question, we are asked to prove the trigonometric identity (cosθ − sinθ)/(cosθ + sinθ) = (1 − tanθ)/(1 + tanθ).

Going by the left-hand side of the equation, we get:

(cosθ − sinθ)/(cosθ + sinθ)

Dividing the numerator and the denominator by cosθ, we get:

{(cosθ − sinθ)/cosθ}/{(cosθ + sinθ)/cosθ}

= {cosθ/cosθ - sinθ/cosθ}/{cosθ/cosθ + sinθ/cosθ}

= (1 - sinθ/cosθ)(1 + sinθ/cosθ).

Using the identity, tanθ = sinθ/cosθ, we get:

(1 - tanθ)/(1 + tan θ)

= The right-hand side of the equation.

Hence the identity has been proved.

Thus, the given trigonometric identity (cosθ − sinθ)(cosθ + sinθ) = (1 − tanθ)(1 + tanθ) has been proved.

we find that the numerical approximation using Euler's method gives y(2) ≈ 1.865, while the analytical solution gives y(2) = 2.5.

Using the formula y(n+1) = y(n) + Δx * f(x(n), y(n)), where f(x, y) = x² √y, we can calculate the values of y at each step. Here's the step-by-step calculation:

Step 1: For x = 0, y = 1 (initial condition).

Step 2: For x = 0.2, y = 1 + 0.2 * (0.2)² * √1 = 1.008.

Step 3: For x = 0.4, y = 1.008 + 0.2 * (0.4)² * √1.008 = 1.024.

Step 4: For x = 0.6, y = 1.024 + 0.2 * (0.6)² * √1.024 = 1.052.

Step 5: For x = 0.8, y = 1.052 + 0.2 * (0.8)² * √1.052 = 1.094.

Step 6: For x = 1.0, y = 1.094 + 0.2 * (1.0)² * √1.094 = 1.155.

Step 7: For x = 1.2, y = 1.155 + 0.2 * (1.2)² * √1.155 = 1.238.

Step 8: For x = 1.4, y = 1.238 + 0.2 * (1.4)² * √1.238 = 1.346.

Step 9: For x = 1.6, y = 1.346 + 0.2 * (1.6)² * √1.346 = 1.483.

Step 10: For x = 1.8, y = 1.483 + 0.2 * (1.8)² * √1.483 = 1.654.

Step 11: For x = 2.0, y = 1.654 + 0.2 * (2.0)² * √1.654 = 1.865.

Therefore, using Euler's method with a step size of Δx = 0.2, we approximate y(2) to be 1.865.

To obtain the analytical solution to the ODE, we can separate variables and integrate both sides:

∫(1/√y) dy = ∫x² dx

Integrating both sides gives:

2√y = (1/3)x³ + C

Solving for y:

y = (1/4)(x³ + C)²

Using the initial condition y(0) = 1, we can substitute x = 0 and y = 1 to find the value of C:

1 = (1/4)(0³ + C)²

1 = (1/4)C²

4 = C²

C = ±2

Since C can be either 2 or -2, the general solution to the ODE is:

y = (1/4)(x³ + 2)² or y = (1/4)(x³ - 2)²

Now, let's evaluate y(2) using the analytical solution:

y(2) = (1/4)(2³ + 2)² = (1/4)(8 + 2)² = (1/4)(10)² = 2.5

Answer:

In the original game, the probability of winning is 4/10 or 2/5. To make the game fair, we want to adjust the number of star cards and blank cards so that the probability of winning is 1/2 or 5/10.

Option 1: Add 2 cards with stars.

If we add 2 cards with stars, we will have a total of 12 cards, 6 of which will have stars. The probability of winning will be 6/12 or 1/2, making the game fair.

Option 2: Add a star to 1 of the blank cards.

If we add a star to 1 of the blank cards, we will have a total of 11 cards, 5 of which will have stars. The probability of winning will be 5/11, which is not exactly 1/2 but is very close. This option is a good approximation of a fair game, but not perfect.

Option 3: Take away 2 blank cards.

If we take away 2 blank cards, we will have a total of 8 cards, 4 of which will have stars. The probability of winning will be 4/8 or 1/2, making the game fair.

Therefore, options 1 and 3 will make the game fair, while option 2 is a good approximation of a fair game.

The correct answer is 0.167.  Given that a random variable Y follows a binomial distribution with n = 17 and p = 0.9, the probability of P(Y > 14) is to be found. Step-by-step

We know that a random variable Y that follows a binomial distribution can be written as Y ~ B(n,p).The probability mass function of binomial distribution is given by: P(Y=k) = n Ck pk q^(n-k)where, n is the number of trials is the number of successful trialsp is the probability of success q = (1-p) is the probability of failure Given n=17 and p=0.9. Probability of getting more than 14 success out of 17 is: P(Y > 14) = P(Y=15) + P(Y=16) + P(Y=17)P(Y=k) = n Ck pk q^(n-k)Now we can calculate P(Y > 14) as follows:

P(Y > 14) = P(Y=15) + P(Y=16) + P(Y=17)= (17C15)(0.9)^15(0.1)^2 + (17C16)(0.9)^16(0.1)^1 + (17C17)(0.9)^17(0.1)^0=0.167

For angle α, we have that 3 is the adjacent side length and 10 is the opposite side length, hence it's measure is given as follows:

tan(α) = 10/3

α = arctan(10/3)

α = 73.3º.

Angle θ is complementary to angle α, as we have a right triangle, hence:

Answer:

135 degrees

Step-by-step explanation:

The other two angle measures of a right triangle with side lengths 5, 12, and 13 can be found using trigonometric ratios. Let's label the sides of the triangle as follows:

- The side opposite the angle we are looking for is 5.
- The side adjacent to the angle we are looking for is 12.
- The hypotenuse is 13.

To find the first angle, we will use the inverse tangent function (tan^(-1)). The formula is:
Angle = tan^(-1)(opposite/adjacent)

Plugging in the values, we get:
Angle = tan^(-1)(5/12)

Using a calculator, we find this angle to be approximately 22.6 degrees (rounded to the nearest degree).

To find the second angle, we will use the fact that the sum of the angles in a triangle is 180 degrees. Therefore, the second angle can be found by subtracting the right angle (90 degrees) and the first angle from 180 degrees.
Second angle = 180 - 90 - 22.6

Calculating this, we find the second angle to be approximately 67.4 degrees (rounded to the nearest degree).

Therefore, the other two angle measures of the right triangle are approximately 23 degrees and 67 degrees.

Both services would charge the same amount at 7.5 miles

From the question, the parameters are:

Food Drivers

Charges = $4

Delivery = $0.25

Totally Take-out

Charges = $3.25

Delivery = $0.35

The linear equation for both companies can be represented as

y = Charges * x + Delivery

So, we have the following equations:

Food drivers: f(x) = 4 + 0.25*x

Totally take-out: g(x) = 3.25 + 0.35*x

Both services charge the same if:

g(x) = f(x)

So we need to solve the linear equation:

4 + 0.25*x =  3.25 + 0.35*x

Collect the like terms

4 - 3.25 = 0.35*x  - 0.25*x

Evaluate the like terms

0.75 = 0.10*x

Divide both sides by 0.10

x = 7.5
