15 ( 1 + 4 ) = 15 × 1 + 15 × 4.

Greatest common factor of 15 and 6 0 is :

Factors of 15 are 1, 3, 5, 15

Factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12,15, 20, 30, 60

Greatest common factor = 15

= 15  + 60

= 15 × 1 + 15 × 4

= 15 ( 1 + 4 )

Distributive property using greatest common factor 15 we get:

15 ( 1 + 4 ) = 15 × 1 + 15 × 4

Therefore, the sum of 15 and 60 in distributive property form using greatest common factor is 15 ( 1 + 4 ) = 15 × 1 + 15 × 4.

For a test concerning a mean, a sample of size n =90 is obtained. In testing H0: u<=u0 versus H1: u>u0, the test statistic is 1.91. Find the p-value (round off to third decimal place).

Answers

The p-value for the given test is approximately 0.028, rounded off to the third decimal place.

To find the p-value for a test concerning a mean, where the sample size is n = 90 and the test statistic is 1.91, we need to determine the probability of observing a test statistic as extreme as or more extreme than the one obtained under the null hypothesis.

Since the alternative hypothesis is u > u0, we are conducting a right-tailed test.

The p-value is the probability of observing a test statistic greater than or equal to the observed test statistic under the null hypothesis.

To calculate the p-value, we can use the cumulative distribution function (CDF) of the appropriate distribution, which in this case is the t-distribution.

Since the sample size is large (n = 90), we can approximate the t-distribution with a standard normal distribution.

Using a standard normal distribution, we can find the p-value as follows:

p-value = 1 - CDF(t), where t is the observed test statistic.

p-value = 1 - CDF(1.91)

Calculating this using a standard normal distribution table or a statistical software, we find that the p-value is approximately 0.028.

Therefore, the p-value for the given test is approximately 0.028, rounded off to the third decimal place.

Tickets for a recent concert cost $20 for adults and 512 for kids. Total attendance for the concert was 840 and total ticket sales were $12.496. How many of each ticket type were sold? a. 2,912 adult tickets, -2,072 kid's tickets b. 212 adult tickets, 628 kid's tickets c. 302 adult tickets, 538 kid's tickets
d. 53 adult tickets, 787 kid's tickets

Answers

The solution is:

Number of adult tickets sold: 53

Number of kid's tickets sold: 787

To solve the problem, let's denote the number of adult tickets sold as A and the number of kid's tickets sold as K. We can then set up a system of equations based on the given information:

Equation 1: A + K = 840 (Total attendance)

Equation 2: 20A + 512K = 12,496 (Total ticket sales)

To find the solution, we can solve this system of equations using the method of substitution or elimination.

Let's go through the options provided:

a. 2,912 adult tickets, -2,072 kid's tickets:

Plugging the values into Equation 1: 2,912 + (-2,072) = 840, which is not true. The total attendance should be a positive number.

b. 212 adult tickets, 628 kid's tickets:

Plugging the values into Equation 1: 212 + 628 = 840, which is true.

Plugging the values into Equation 2: 20(212) + 512(628) = 12,496, which is true.

c. 302 adult tickets, 538 kid's tickets:

Plugging the values into Equation 1: 302 + 538 = 840, which is true.

Plugging the values into Equation 2: 20(302) + 512(538) = 12,496, which is true.

d. 53 adult tickets, 787 kid's tickets:

Plugging the values into Equation 1: 53 + 787 = 840, which is true.

Plugging the values into Equation 2: 20(53) + 512(787) = 12,496, which is true.

From the options provided, both options b and d satisfy both equations. However, we need to ensure that the number of tickets sold cannot be negative, so option d is the correct answer.

Therefore, the solution is:

Number of adult tickets sold: 53

Number of kid's tickets sold: 787

Answers

Answer:

99 and 33

Step-by-step explanation:

let x and y be the 2 numbers, with x being the larger of the 2, then

x + y = 132 → (1)

x - y = 66 → (2)

add (1) and (2) term by term to eliminate y

(x + x) + (y - y) = 132 + 66

2x + 0 = 198

2x = 198 ( divide both sides by 2 )

x = 99

substitute x = 99 into (1) and solve for y

99 + y = 132 ( subtract 99 from both sides )

y = 33

the 2 numbers are 99 and 33

How can we convert cm2 to m2?

Answers

To convert cm² to m², simply multiply the number of cm² by 0.0001. For example, if you have an area measurement of 2 cm², you would multiply 2 by 0.0001 to get 0.0002 m². It is also important to note that when converting cm² to m², you are essentially just moving the decimal place four places to the right.

The same result can be achieved by dividing the number of cm² by 10,000. For example, if you have an area measurement of 2 cm², you would divide 2 by 10,000 to get 0.0002 m2. Converting cm² to m² is a useful skill for anyone who uses the metric system for measuring area.

Converting cm² to m² is simple and straightforward. To begin, it is important to first understand the basic units of measure for area in the metric system. Centimeters squared (cm²) are the standard unit of measure for area in the metric system. One cm² is equal to 0.0001 m².

(2) Deer Creek is found in a mountainous area above a flat broad valley and flows for 8 km. The creek's source is found at 2700 meters above sea level and comes out onto the valley floor at 1290 meters above sea level. What is the slope of the stream?

(Round to two decimal places.) Calculate in meters per kilometer: m/km and then meters per meter m/m

(3) You are using a topographic map to do fieldwork in mountainous terrain. You need to hike over a ridge to get to the field area that you are interested in. The trail to the place you want to be is about 3.5 inches on the map, which has a scale of 1:24000.

How many inches on the ground does 3.5 inches on the map represent? (Round your answer to the nearest inch)

How many feet does 3.5 inches on the map represent? (Round your answer to the nearest foot.)

How many miles does 3.5 inches on the map represent? (Round your answer to the nearest tenth of a mile.)

Answers

1. The slope of the water table between the two wells can be calculated by determining the difference in water table levels and dividing it by the distance between the wells. 2. The slope of Deer Creek can be determined by calculating the difference in elevation between its source and the valley floor and dividing it by the length of the creek. 3. To determine the ground measurements corresponding to 3.5 inches on the map, we need to use the map's scale. The scale of 1:24000 means that 1 inch on the map represents 24000 inches on the ground.

1. To calculate the slope of the water table between the wells, we subtract the water table level at one well (100 feet) from the level at the other well (300 feet), resulting in a difference of 200 feet. Since the wells are half a mile apart (2640 feet), we divide the difference in water table levels by the distance between the wells, giving us a slope of approximately 0.076 ft/mi.

2. The slope of Deer Creek can be determined by subtracting the elevation of its source (2700 meters) from the elevation at the valley floor (1290 meters), resulting in a difference of 1410 meters. Since the creek flows for 8 kilometers, we divide the elevation difference by the length of the creek, giving us a slope of approximately 176.25 m/km or 0.176 m/m.

3. To determine the ground measurements corresponding to 3.5 inches on the map, we use the scale of 1:24000. Since 1 inch on the map represents 24000 inches on the ground, 3.5 inches on the map would represent 84000 inches on the ground, which is approximately 7000 feet or 1.32 miles.

Answer:

  (x, y) = (-244/29, -80/29)

Step-by-step explanation:

A graph (2nd attachment) shows the solution to be non-integer values, so we'll use the "cross multiply method" to find the solution.

Rewriting the equations to general form gives ....

  2x -9y -8 = 0

  5x -8y +20 = 0

Writing the coefficients in two rows of four, we have the table as in the first attachment. (The first column is repeated as the 4th column.)

Now, the cross product differences are formed. Each "orange" cross product difference is the difference of the product of "blue" coefficients and the product of "yellow" coefficients. The same formula is copied to the right.

These difference numbers go, left to right, into the form ...

  1/p1 = x/p2 = y/p3 . . . . . . where p1, p2, p3 are the cross product differences

In this problem, the solution is ...

  x = -244/29 ≈ -8.414

  y = -80/29 ≈ -2.759

2x-9y=8 -5x+8y=20 find x and y

Answers

We cannot conclude that listening to Mozart will lead to much higher scores on an IQ test based on the given information.

While the mean IQ scores were 1.2 points higher after listening to Mozart, the statistical significance of this difference depends on the chosen level of significance (alpha level) and the sample size. The p-value of 0.0004 indicates that if there is no difference in IQ scores between the Mozart and silent background conditions in the population, there is only a 0.04% chance of observing a sample mean difference of 1.2 points or larger. However, we would need to know the alpha level and sample size used in the study to determine if this is statistically significant at a practical level.
