The rate of change of y = cos x with respect to time is approximately -1.46 cm/sec.

This problem involves finding the rate of change of the dependent variable (y = cos x) with respect to the independent variable (x) at a given rate of change of the independent variable (dx/dt = 4 cm/sec).

Using the chain rule of differentiation, we have:

dy/dt = dy/dx * dx/dt

Taking the derivative of y = cos x with respect to x, we get:

dy/dx = -sin x

Substituting the given value of dx/dt = 4 cm/sec and the value of sin x can be obtained using the identity cos² x + sin² x = 1 and the given value of cos x = cos 0 = 0.95, we get:

dy/dt = dy/dx * dx/dt

= (-sin x) * 4

= (-√(1 - cos² x)) * 4 [Using the identity sin x = √(1 - cos² x)]

= (-√(1 - 0.95²)) * 4

≈ -1.46 cm/sec

Therefore, the rate of change of y = cos x with respect to time is approximately -1.46 cm/sec.

Assume that the test scores of a college entrance exam fits a normal distribution. the mean test score is 80, and the standard deviation is 5. The percentage of students scoring 83 or more in the exam is 26.96%.

Assuming that the test scores of a college entrance exam fit a normal distribution with mean 80 and standard deviation 5, the z-score of a test score of 83 is calculated using the formula:

z = (x - μ) / σ

where z is the z-score,

x is the test score,

μ is the mean, and

σ is the standard deviation.

Substituting the values, we get:

z = (83 - 80) / 5 = 0.6

Using a z-table or a calculator, we find that the percentage of students scoring 83 or more is the area to the right of the z-score of 0.6 under the standard normal distribution curve.

This can be calculated as:

P(z > 0.6) = 1 - P(z < 0.6)

Using a z-table or a calculator, we can find that P(z < 0.6) = 0.7257

Therefore,P(z > 0.6) = 1 - P(z < 0.6) = 1 - 0.7257 = 0.2743

Multiplying by 100%, we get that the percentage of students scoring 83 or more in the exam is:

The percentage of mail deliveries that are made after 5:00 p.m is 33.3%.

The continuous uniform distribution is a probability distribution that is used when all outcomes are equally likely, and they are spread out over a given interval.

In this case, the interval is from 1:00 p.m. to 6:00 p.m.

To determine the percentage of mail deliveries that occur after 5:00 p.m., we need to calculate the probability that the delivery time falls after 5:00 p.m.

The probability of a delivery time falling after 5:00 p.m. can be found by subtracting the probability of it falling before 5:00 p.m. from 1.

The probability of a delivery time falling before 5:00 p.m. is found by calculating the area under the probability density curve between 1:00 p.m. and 5:00 p.m.

This can be found using the following formula:

P(x ≤ 5:00 p.m.) = (5:00 p.m. – 1:00 p.m.) / (6:00 p.m. – 1:00 p.m.)

This gives us a probability of 0.667.

Therefore, the probability of a delivery time falling after 5:00 p.m. is 1 – 0.667 = 0.333, or 33.3%.

This means that 33.3% of the daily mail deliveries are made after 5:00 p.m.

We can approach this problem using exponential decay, where the number of bacteria decreases by 60% per day. Let N be the initial number of bacteria on Wednesday, then the number of bacteria on Friday can be calculated as:

N_Friday = N_Wednesday x (0.4)^2

where (0.4)^2 is the factor by which the number of bacteria decreases from Wednesday to Friday.

We are given that the number of bacteria on Wednesday is 2.4 x 10, so we can substitute this into the equation:

N_Friday = 2.4 x 10 x (0.4)^2

Simplifying this expression, we get:

N_Friday = 0.96

Therefore, the number of bacteria that will be detected in the laboratory test on Friday is 0.96. Note that the units are not specified in the question, so we assume that the number is given in some arbitrary units.

The probability that it will take at least 5 minutes until the student is served when he enters the restaurant today is 50%.

This is because there is an equal chance that it could take less than 5 minutes or more than 5 minutes until the student is served.

In probability terms, the student's wait time is a random variable with two possible outcomes - wait time less than 5 minutes, or wait time greater than or equal to 5 minutes. Since there is an equal chance of either outcome occurring, the probability of the wait time being greater than or equal to 5 minutes is 50%.

This is also known as the Law of Large Numbers.

To further illustrate this concept, imagine that the student flips a fair coin. The two possible outcomes of the coin toss are heads or tails. Since each outcome has an equal chance of occurring, the probability of either heads or tails is 50%.

In this case, the probability of the student's wait time being at least 5 minutes is the same as the probability of the coin toss being heads or tails, hence making the probability 50% or 0.5.

Here, P is the principal amount (£6000), t is the time period (5 years), and I is the interest earned (£450). Substituting these values in the formula gives us: 450 = 6000 * r * 5. Solving for r, we get r = 0.015 or 1.5%. Therefore, the account pays a simple interest rate of 1.5%

Answer: 18.75%

Step-by-step explanation:

To find the percent increase, we need to calculate the difference between the new speed and the old speed, divide that by the old speed, and then multiply by 100 to get the percentage increase.

The difference between the new speed and the old speed is:

38 - 32 = 6

To find the percentage increase, we divide the difference by the old speed and multiply by 100:

(6 / 32) x 100 = 18.75%

Therefore, Matt's typing speed increased by 18.75%.

(a) To test the hypotheses H0: µ = 115 and H1: µ > 115, we will conduct a one-sample t-test using the given information.

Step 1: Calculate the t-value.
t = (sample mean - population mean) / (standard deviation / √sample size)
t = (127.8 - 115) / (30 / √25)
t = 12.8 / 6
t = 2.13

Step 2: Determine the degrees of freedom (df).
df = sample size - 1
df = 25 - 1
df = 24

Step 3: Find the P-value.
Using a t-table or calculator, find the P-value corresponding to t = 2.13 and df = 24. The P-value is approximately 0.022.

Step 4: State the conclusion.
Since the P-value is less than the commonly used significance level of 0.05, we reject the null hypothesis (H0: µ = 115) and conclude that the mean score for older students is significantly higher than the mean score for the entire population.

(b) The two important assumptions for the t-test are:
1. The sample is randomly selected from the population.
2. The population is normally distributed.

The most important assumption for the validity of the conclusion in part (a) is the normality of the population. If the population is not normally distributed, the results of the t-test may not be valid, and the conclusion may be inaccurate.

The vertex is (9, 3), the width of the parabola is 2/3 units, the axis of symmetry is the vertical line passing through x = 9.

f(x) = ax2 bx c, where x is the variable and a, b, and c are constants, is the formula for a quadratic function. It falls under the category of a degree two polynomial function.

In the given equation of a quadratic function:

f(x) = (1/9)(x - 9)² + 3

The vertex is (h, k), where h and k are the x-coordinate and y-coordinate of the vertex, respectively.

Here, the equation is in vertex form:

f(x) = a(x - h)² + k

Comparing this to the given equation, we can see that h = 9 and k = 3. Therefore, the vertex is (9, 3).

The opening of the parabola is upward because the coefficient "a" of the quadratic term (x - h)² is positive (1/9 in this case).

The width of the parabola can be determined using the formula:

w = 2√(a/k)

where a is the coefficient of the quadratic term and k is the y-coordinate of the vertex.

Plugging in the values, we get:

w = 2√[(1/9)/3] = 2/3

Therefore, the width of the parabola is 2/3 units.

The axis of symmetry is a vertical line that passes through the vertex and divides the parabola into two equal halves.The axis of symmetry's equation is as follows:.

x = h

Substituting h = 9, we get:

x = 9

Therefore, the axis of symmetry is the vertical line passing through x = 9.

Step-by-step explanation:

the concentrations of nitrogen, phosphate, and potassium in the mixture are 13.33%, 13.67%, and 8%, respectively. To find the concentrations of nitrogen, phosphate, and potassium in the mixture, we need to calculate the total amount of each nutrient in the two bags and then divide by the total weight of the mixture.

First, let's calculate the amount of each nutrient in the 10 pound bag of 12-12-12:

Nitrogen: 12% of 10 pounds = 1.2 pounds

Phosphate: 12% of 10 pounds = 1.2 pounds

Potassium: 12% of 10 pounds = 1.2 pounds

Next, let's calculate the amount of each nutrient in the 5 pound bag of 16-17-0:

Nitrogen: 16% of 5 pounds = 0.8 pounds

Phosphate: 17% of 5 pounds = 0.85 pounds

Potassium: 0% of 5 pounds = 0 pounds

Now, let's add up the total amount of each nutrient in the two bags:

Nitrogen: 1.2 + 0.8 = 2 pounds

Phosphate: 1.2 + 0.85 = 2.05 pounds

Potassium: 1.2 + 0 = 1.2 pounds

Finally, let's divide the total amount of each nutrient by the total weight of the mixture (10 + 5 = 15 pounds) and express the answers as percentages:

Nitrogen: (2 / 15) x 100% = 13.33%

Phosphate: (2.05 / 15) x 100% = 13.67%

Potassium: (1.2 / 15) x 100% = 8%

Therefore, the concentrations of nitrogen, phosphate, and potassium in the mixture are 13.33%, 13.67%, and 8%, respectively.
