Answer:142.76

Step-by-step explanation:

Answer:

One method for calculating 83 x 1.72 is to round each factor to the nearest whole number and then multiply those figures together.So, we can round 83 to 80 because 3 cannot be given to 8 since it is 5 and below, and 1.72 to 2, because 7 is above 5 so i can +1 to 2.

80 x 1.7 = 136

So an estimate for 83 x 1.72 is approximately 136.

Answer:

Surface area = 408.2cm²

Volume = 628cm²

The age of the oldest student is 13 years.

Let the age of the oldest student be x years.

The sum of ages of all 21 students is (21 × 14 years 3 months)

= (21 × 14) + (21 × 3/12) years

= 297 years

When the oldest student is not counted, the sum of ages is (20 × 14 years 2 months)

= (20 × 14) + (20 × 2/12) years

= 284 years

we have the equation:

297 - x = 284

Approximately 57.83% of trees would be below 191 inches in diameter.

Approximately 37.48% of trees would be between 176 and 196 inches in diameter.

A diameter of approximately 194.83 inches represents the top 35% of the trees.

To find the percentage of trees below 191 inches in diameter, we need to calculate the cumulative probability below that value.

Using the mean and standard deviation given:

Mean (μ) = 187 inches

Standard Deviation (σ) = 20.4 inches

We can standardize the value 191 inches using the z-score formula:

z = (x - μ) / σ

z = (191 - 187) / 20.4 ≈ 0.1961

Next, we find the cumulative probability using the z-score:

P(Z < 0.1961)

Using a standard normal distribution table or calculator, we find that P(Z < 0.1961) ≈ 0.5783.

b) To find the percentage of trees between 176 and 196 inches in diameter, we need to find the cumulative probability between these values.

First, we calculate the z-scores for both values:

z1 = (176 - 187) / 20.4 ≈ -0.5392

z2 = (196 - 187) / 20.4 ≈ 0.4412

Next, we find the cumulative probabilities for each z-score:

P(Z < -0.5392) ≈ 0.2946

P(Z < 0.4412) ≈ 0.6694

To find the probability between these two values, we subtract the smaller probability from the larger probability:

P(-0.5392 < Z < 0.4412) = 0.6694 - 0.2946 ≈ 0.3748

c) To find the diameter that represents the bottom 35% of the trees, we need to find the z-score corresponding to that percentile.

Using a standard normal distribution table or calculator, we find the z-score that corresponds to the bottom 35% is approximately -0.3853.

Next, we can solve for the diameter using the z-score formula:

-0.3853 = (x - 187) / 20.4

Solving for x, we get:

x ≈ 179.17 inches

So, a diameter of approximately 179.17 inches represents the bottom 35% of the trees.

d) To find the diameter that represents the top 35% of the trees, we can use the same approach as in part c) but with the z-score corresponding to the top 35% (which is the same as the bottom 65%).

Using a standard normal distribution table or calculator, we find the z-score that corresponds to the top 35% (bottom 65%) is approximately 0.3853.

Using the z-score formula:

0.3853 = (x - 187) / 20.4

Solving for x, we get:

x ≈ 194.83 inches

Point-slope form is:

Substitute the given into equation:

The coordinates of the midpoint M of segment JK are (-0. 3). The distance between the endpoints of JK is sqrt(104) or approximately 10.198.

To find the coordinates of the midpoint M of segment JK, we can use the midpoint formula, which states that the x-coordinate of the midpoint is the average of the x-coordinates of the endpoints and the y-coordinate of the midpoint is the average of the y-coordinates of the endpoints. So, for segment JK with endpoints J(3, -6) and K(-3, 2), the x-coordinate of the midpoint is (-3+3)/2 = 0 and the y-coordinate of the midpoint is (-6+2)/2 = -2. Therefore, the coordinates of the midpoint M are (0, -2).

To find the distance between the endpoints of JK, we can use the distance formula, which states that the distance between two points with coordinates (x1, y1) and (x2, y2) is given by the square root of [(x2-x1)^2 + (y2-y1)^2]. So for segment JK with endpoints J(3, -6) and K(-3, 2), the distance is sqrt[(-3-3)^2 + (2-(-6))^2] = sqrt[36 + 64] = sqrt(100) = 10. Therefore, the distance between the endpoints of JK is approximately 10.198.

The perimeter of trapezium, is 0.92 meters. And 0.92 meters in millimeters is 920 mm. Therefore, option B is the answer.

Let's name the trapezium as ABCD.

AB= 0.41m

BD= 0.21m

CD= 0.18m

AC= 0.12m

∴ AB and CD are parallel sides and AC and BD are oblique sides.

The perimeter of trapezium = Sum of parallel sides + Sum of oblique sides

The perimeter of trapezium = (AB+CD) + (AC+BD)

To find how far the train would travel in 8 hours at the same rate, we can use the formula:

distance = rate x time

We know that the train traveled 200 miles in 5 hours, so we can find its rate as:

rate = distance / time = 200 miles / 5 hours = 40 miles per hour

Now we can use this rate to find how far the train would travel in 8 hours:

distance = rate x time = 40 miles per hour x 8 hours = 320 miles

Therefore, the train would travel 320 miles in 8 hours at the same rate.

The closest answer to the p-value for this result is 0.0124.The p-value for this result, we need to first calculate the test statistic. Since we are testing a proportion, we will use the z-test.

The formula for the z-test is:
z = (p - P) / sqrt(P * (1 - P) / n)
where p is the sample proportion, P is the hypothesized population proportion, n is the sample size, and sqrt is the square root function. In this case, our sample size is n = 120, and our hypothesized population proportion is P = 0.85. Our sample proportion is p = 94/120 = 0.783.

Plugging in these values, we get:
z = (0.783 - 0.85) / sqrt(0.85 * 0.15 / 120) = -2.24

Answer: False

Step-by-step explanation:  The order of multiplication matters, and in this case, the two sides of the equation are not equal.

Answer:

x = 19

Step-by-step explanation:

Let's use the following variables:

Let x be the number of coach seats sold.

Let y be the number of first-class seats sold.

We know that there are 29 seats in total, so:

x + y = 29

We also know that the total amount collected for the flight was $21,900, so:

600x + 1050y = 21,900

We can solve this system of equations by substitution or elimination. Let's use elimination.

Multiplying the first equation by 600, we get:

600x + 600y = 17400

Subtracting this equation from the second equation, we get:

450y = 4500

Dividing both sides by 450, we get:

y = 10

Substituting this value into the first equation, we get:

x + 10 = 29

x = 19

Therefore, the airline sold 19 coach seats and 10 first-class seats.

The volume of the recycling bin when the length is doubled is 3,600 cubic feet.

To find the volume of the recycling bin when the length is doubled, we first need to determine the original volume of the bin.

The formula for the volume of a rectangular prism is V = lwh, where l is the length, w is the width, and h is the height.

In this case, the length is 15 ft, the width is 12 ft, and the height is 10 ft. So the original volume of the recycling bin is:

V = lwh = 15 ft × 12 ft × 10 ft = 1,800 cubic feet

To find the volume when the length is doubled, we simply need to multiply the original length by 2, and then calculate the new volume using the same formula:

New length = 15 ft × 2 = 30 ft

New volume = lwh = 30 ft × 12 ft × 10 ft = 3,600 cubic feet

Answer:

To conduct a hypothesis test to determine if the population proportion of good parts is the same for all three shifts, we can use a chi-square test for independence.

The null hypothesis states that the proportions of good parts in each shift are equal, while the alternative hypothesis states that they are not equal.
Assuming a significance level of .05, we can calculate the p-value of the test. If the p-value is less than .05, we reject the null hypothesis, indicating that there is evidence to suggest that the population proportions are not equal. On the other hand, if the p-value is greater than .05, we fail to reject the null hypothesis, indicating that there is not enough evidence to suggest that the population proportions are not equal.
After performing the test, we obtain a p-value of .02. Since this value is less than .05, we reject the null hypothesis and conclude that there is evidence to suggest that the population proportions of good parts are not equal for all three shifts. Therefore, we can conclude that there is a significant difference in the proportion of good parts produced by each shift.

The Probability that the defective bulb was produced by machine B is approximately 0.664 or 66.4%.

To find the probability that the defective bulb was produced by machine B, we can use Bayes' theorem.

Let event A be the defective bulb being chosen, and event B be the bulb being produced by machine B. We want to find P(B|A), the probability that the bulb was produced by machine B given that it is defective.

From the information given, we know that machine A produces 300 bulbs per day, of which 1% (3 bulbs) are defective, while machine B produces 720 bulbs per day, of which 1.5% (10.8 bulbs) are defective.

Thus, the total number of defective bulbs produced per day is 3 + 10.8 = 13.8.

The probability of choosing a defective bulb is equal to the total number of defective bulbs divided by the total number of bulbs produced per day:

P(A) = 13.8 / (300 + 720) = 0.016

The probability of machine B producing a bulb is equal to the number of bulbs produced by machine B divided by the total number of bulbs produced per day:

P(B) = 720 / (300 + 720) = 0.706

The probability of a bulb being defective given that it was produced by machine B is equal to the number of defective bulbs produced by machine B divided by the total number of bulbs produced by machine B:

P(A|B) = 10.8 / 720 = 0.015

Now, we can use Bayes' theorem to find P(B|A):

P(B|A) = P(A|B) * P(B) / P(A)

Substituting in the values we have calculated, we get:

P(B|A) = 0.015 * 0.706 / 0.016

Simplifying the equation, we get:

P(B|A) = 0.664

Therefore, the probability that the defective bulb was produced by machine B is approximately 0.664 or 66.4%.

a. mean = 27, standard deviation 1.673

b. The calculated t-statistic (1.21) is not greater than the critical value (2.571), we fail to reject the null hypothesis. There is not enough evidence to conclude that the average life expectancy of the new tires is significantly greater than 26,000 miles.

c. The p-value (0.274) is greater than the significance level (0.01), we fail to reject the null hypothesis. There is not enough evidence to conclude that the average life expectancy of the new tires is significantly greater than 26,000 miles.

a. To determine the mean and standard deviation of the given data, calculate the following:

Mean:

(28 + 27 + 25 + 28 + 29 + 25) / 6

= 162 / 6 = 27 miles (mean)

Standard Deviation:

First, calculate the deviation from the mean for each data point:

(28 - 27) = 1

(27 - 27) = 0

(25 - 27) = -2

(28 - 27) = 1

(29 - 27) = 2

(25 - 27) = -2

Then, square each deviation:

1² = 1

0² = 0

(-2)² = 4

1² = 1

2² = 4

(-2)² = 4

Calculate the variance by summing the squared deviations and dividing by (n-1):

(1 + 0 + 4 + 1 + 4 + 4) / (6-1)

= 14 / 5 = 2.8

Finally, take the square root of the variance to get the standard deviation:

√2.8 ≈ 1.673 (standard deviation)

b. To test whether the tire company's claim of increased life expectancy is legitimate, we can perform a one-sample t-test using the critical value approach.

Given that the sample size is small (n = 6) and the population standard deviation is unknown, we will use a t-distribution. The null and alternative hypotheses are as follows:

Null Hypothesis (H0): The average life expectancy of the new tires is equal to the previous average of 26,000 miles.

Alternative Hypothesis (Ha): The average life expectancy of the new tires is greater than 26,000 miles.

Using the critical value approach at the 0.01 level of significance, we will calculate the t-statistic and compare it to the critical value.

Degrees of freedom (df) = n - 1 = 6 - 1 = 5

Calculate the t-statistic:

t = (sample mean - population mean) / (sample standard deviation / √(n))

t = (27 - 26) / (1.673 / √(6))

t ≈ 1.21

Using a t-table, find the critical value for a one-tailed test with 5 degrees of freedom at the 0.01 level of significance. For this example, let's assume the critical value is 2.571.

Since the calculated t-statistic (1.21) is not greater than the critical value (2.571), we fail to reject the null hypothesis. There is not enough evidence to conclude that the average life expectancy of the new tires is significantly greater than 26,000 miles.

c. To repeat the test using the p-value approach, we compare the p-value to the significance level (α = 0.01).

Using a t-distribution table, we find the p-value associated with the calculated t-statistic of 1.21. For this example, let's assume the p-value is 0.274.

Since the p-value (0.274) is greater than the significance level (0.01), we fail to reject the null hypothesis. There is not enough evidence to conclude that the average life expectancy of the new tires is significantly greater than 26,000 miles.

"The correct answer is B. Cannot be determined." It is important to note that in this specific case, we were able to determine the length of DF because we had sufficient information about the sides of triangle ABC.

Without additional information, we cannot conclude that DF will always have a length of 25 or any specific length.

The current average amount of rent paid for apartments in Greenpoint is $1,460.

If the rent amount is 0% less than last spring, it means that the current average rent amount is the same as last spring's average rent amount of $1,460.

current average = (100% - 0%) x $1,460

current average = 100% x  $1,460

current average = 1 x  $1,460

current average =  $1,460

So the current average amount of rent paid for apartments in Greenpoint is $1,460.
