1) The sample proportion is 0.14 (7 left-handed students out of 50 total students surveyed).
2) The hypothesized proportion po is 0.10 (the usual proportion of left-handed students).
3) The sample size n is 50 (the number of students surveyed).
4) The test statistic z is 1.32.

1) The sample proportion is calculated by dividing the number of left-handed students by the total number of students surveyed. In this case, 7 left-handed students out of 50 gives a sample proportion of 7/50 = 0.14.
2) The hypothesized proportion (p₀) is the usual proportion of left-handed students, which is given as 0.10.
3) The sample size (n) is the total number of students surveyed, which is 50.
4) The test statistic (z) can be calculated using the formula: z = (sample proportion - hypothesized proportion) / sqrt((hypothesized proportion * (1 - hypothesized proportion)) / sample size). In this case, z = (0.14 - 0.10) / sqrt((0.10 * (1 - 0.10)) / 50) = 0.04 / sqrt(0.09 / 50) ≈ 0.943.
To calculate the test statistic z, we use the formula:

z = (sample proportion - hypothesized proportion) / standard error

The standard error is calculated as:

standard error = sqrt((po * (1-po)) / n)

Plugging in the values, we get:

standard error = sqrt((0.10 * (1-0.10)) / 50) = 0.0499

Then,

z = (0.14 - 0.10) / 0.0499 = 1.32

Since the calculated z-value of 1.32 is greater than the critical value of 1.645 (using a significance level of 0.05 for a two-tailed test), we can conclude that there is not enough evidence to reject the null hypothesis that the proportion of left-handed students at the school is the same as the usual proportion of 0.10.

It says that the landscaping company uses 3 1/2 tons the first month and then it says the next month uses the same amount on each of the five prodjects so for every one project in the second month they use 3 1/2 tons.

Using proportion, we can see that 5 pitchers will serve 40 people if 1/8 pitcher served one person.

Given that,

1/8 pitcher served one person.

Let x be the number of people that the 5 pitchers served.

We can find the value using the proportional method.

Using the proportional concept, the ratio of the number of pitchers served to the number of people will be proportional.

So,

(C) No one is taller than Bob and no one different from Bob is the same height as Bob: ∀x [(x ≠ B) → T(B, x)] ∧ ∀y [(y ≠ B ∧ ¬(y = B ∧ H(B, y))) → T(y, B)]

In (P), we have used the universal quantifier ∀ to express that the statement applies to all people x. The symbol ≠ denotes "not equal to", and the predicate T(a, b) represents "a is taller than b". So, the formula states that for all x, if x is not Bob, then Bob is taller than x.

In (C), we have combined two quantified statements using the conjunction operator ∧. The first statement ∀x [(x ≠ B) → T(B, x)] is the same as in (P), and it means that no one is taller than Bob. The second statement ∀y [(y ≠ B ∧ ¬(y = B ∧ H(B, y))) → T(y, B)] uses a new predicate symbol H(a,b) to represent "a is the same height as b". The formula says that for all y, if y is not Bob and y is not the same height as Bob, then y is shorter than Bob.

(b) The argument is invalid. To show this, we need to construct a model in which (P) is true and (C) is false. Let's consider a universe of discourse with three people: Alice, Bob, and Charlie. We can assign the following heights to them:

Alice is shorter than Bob

Bob is the same height as Charlie

So, we have H(A, B), ¬H(A, C), and H(B, C). Note that we have not specified the relative heights of Bob and Charlie, so they could be the same or Bob could be taller.

Now, let's interpret the predicate T(a, b) as "a is at least as tall as b", so T(B, A) and T(C, B). The formula for (P) is true in this model, since there is no person taller than Bob.

However, the formula for (C) is false, because Charlie is not shorter than Bob. In fact, they are the same height according to our assignment. So, we have a counterexample that shows the argument is invalid.

If a train travels 75 feet in 44 seconds. At the same speed, it travels 8.52 feet in 5 seconds

To find out how many feet the train will travel in 5 seconds at the same speed, first, we need to determine the speed of the train.

The train travels 75 feet in 44 seconds. To find the speed, we'll divide the distance traveled (75 feet) by the time taken (44 seconds):

Speed = Distance / Time
Speed = 75 feet / 44 seconds

Now, we can calculate the distance the train will travel in 5 seconds at the same speed:

Distance = Speed × Time
Distance = (75 feet / 44 seconds) × 5 seconds

The "seconds" unit cancels out, and we're left with:

Distance = (75 feet / 44) × 5

Now, we can calculate the distance:

Distance ≈ 8.52 feet

Answer:

Deon drove 270 miles.

Let x be the number of miles driven.

The total cost is 20.95 + 0.74x = 221.49

Subtracting 20.95 from both sides gives 0.74x = 200.54

Dividing both sides by 0.74 gives x = 270 miles

So the answer is 270

Answer:

271 miles

Step-by-step explanation:

The equation to find the total cost is

C = 20.95 + .74 m  where m is the number of miles

221.49 = 20.95 +.74m

Subtract 20.95 from each side

221.49 -20.95 = 20.95-20.95 +.74m

200.54 = .74m

Divide each side by .74

200.74/.74 = m

The f'(x) has two x-intercepts, but f''(x) is always positive, indicating that f(x) has no relative extrema. This means that the function is either always increasing or always decreasing, and there are no maximum or minimum points.

The function f(x) =

[tex](1/3)x^3 - (2/7)x^2 - 1x[/tex]

has no relative extreme points. To find the relative extreme points of a function, we need to find the critical points where either the derivative f'(x) is equal to zero or the second derivative f''(x) is equal to zero.

Taking the derivative of f(x), we get f'(x) = x^2 - (4/7)x - 1. Setting f'(x) equal to zero and solving for x, we get x =

[tex](2 ± \sqrt{} (30))/7[/tex]

Upon further analysis of the second derivative f''(x) = 2x - (4/7), we see that it is always positive for all values of x.

There are no relative extreme points as the function f(x) does not have any points where the slope is zero and the curvature changes from positive to negative or vice versa.

Answer:

The sum of two dice can range from 2 to 12. To get a sum of 3, the only possible combinations are (1,2) and (2,1), since there is only one way to get each of those sums.

There are a total of 6 x 6 = 36 possible outcomes when two dice are rolled, since each die has 6 possible outcomes.

Therefore, the probability of rolling a sum of 3 is:

P(D1 + D2 = 3) = number of ways to get a sum of 3 / total number of possible outcomes

P(D1 + D2 = 3) = 2 / 36

Simplifying by dividing both the numerator and denominator by 2, we get:

a. we are 99% confident that the true population mean time Americans spend eating or drinking per day falls between 1.166 and 1.274 hours.

b.  There will be 70 sample is required to estimate the mean time Americans spend eating or drinking per day within 15 minutes of the true mean and with 95% confidence

(a) To construct a 99% confidence interval for the mean time Americans spend eating or drinking per day, we can use the formula:

CI = x ± z*(σ/√n)

where x is the sample mean, σ is the population standard deviation (which is unknown, so we use the sample standard deviation), n is the sample size, and z* is the critical value for a 99% confidence interval (which we can find using a table or calculator).

Plugging in the values given, we get:

CI = 1.22 ± 2.58*(0.65/√1001) ≈ 1.22 ± 0.054

So the 99% confidence interval for the mean time Americans spend eating or drinking per day is (1.166, 1.274) hours.

We can interpret this interval as saying that we are 99% confident that the true population mean time Americans spend eating or drinking per day falls between 1.166 and 1.274 hours.

(b) To find the sample size required to estimate the mean time Americans spend eating or drinking per day within 15 minutes of the true mean with 95% confidence, we can use the formula:

n = (z*σ/E)^2

where E is the margin of error (which is 15 minutes = 0.25 hours), z* is the critical value for a 95% confidence interval (which is 1.96), and σ is the sample standard deviation (which is 0.65).

Plugging in the values given, we get:

n = (1.96*0.65/0.25)^2 ≈ 69.88

So we need a sample size of at least 70 to estimate the mean time Americans spend eating or drinking per day within 15 minutes of the true mean with 95% confidence.

1. Make an equation. To stay balanced the sum of everything on the left must equal the value on the right.

2 + x + 2 + x + 2 + x + 2 + x + 2 + x = 11

2. Add all like terms. We have 2+2+2+2+2 = 10 and x+x+x+x+x=5x so the equation simplifies to

10 + 5x = 11

3. Substract 10 from both sides

10 - 10 + 5x = 11 - 10

0 + 5x = 1

5x = 1

To find the percentage of batteries that fail to meet the guarantee, we need to calculate the probability that the battery lasts less than 40 hours. Since we know that the length of life of these batteries is normally distributed with mean 50 and variance 16, we can use the z-score formula:

z = (x - μ) / σ

where x is the value we want to find the probability for (in this case, x = 40), μ is the mean (μ = 50), and σ is the standard deviation (σ = sqrt(16) = 4).

So, we have:

z = (40 - 50) / 4 = -2.5

Looking up the probability for a z-score of -2.5 in a standard normal distribution table, we find that the probability is 0.0062, or 0.62%.
