Answer:

Step-by-step explanation:

You are asked only for the setup, not the solution.

I find it convenient to use variable names that remind me of what they stand for. Here, we're asked for the admission prices for adults and children, so 'a' and 'c' are convenient variables to represent those values.

  Let a represent the admission price for an adult.

  Let c represent the admission price for a child.

__

The first sentence gives a relation between the numbers and the total cost:

  162 = 12c +3a

The second sentence gives a different relation:

  122 = 8c +3a

These are the "system of equations."

_____

You aren't asked for the solution, but it is (a, c) = (14, 10). It can be found easily by subtracting the second equation from the first.

this is a right triangle so you can use the Pythagorean Theorem:

6² + x² = 15²

x = [tex]\sqrt{225-36}[/tex] = [tex]\sqrt{189}[/tex] ≈ 13.748

Answer:

$5760

Step-by-step explanation:

Given data

Principal= $8,000

Tax= 28%

Let us compute 28% tax deduction

=28/100*8000

=0.28*8,000

=$2240

Hence the net expenses is

=8000 -2240

=$5760

Answer:

27

Step-by-step explanation:

4/3b=25+11, 4/3b=36,b = 36*3/4 so b = 27

Answer: X = 12, Y = 5

Step-by-step explanation:

4x-27 = x+9

   +27      +27

4x = x + 36

-x     -x

3x = 36

3x/3 = 36/3

X = 12

3y + 19 = 11y - 21

     +21          +21

3y + 40 = 11y

-3y           -3y

40 = 8y

40/8 = 8y/8

Y = 5

The values of x and y are 12 and 5, respectively

The given parameters are:

The slant sides of an isosceles trapezoid are equal.

So, we have:

[tex]EH =FG[/tex]

This gives

[tex]4x - 27 = x + 9[/tex]

Collect like terms

[tex]4x - x = 27 + 9[/tex]

[tex]3x = 36[/tex]

Divide through by 3

[tex]x = 12[/tex]

Also, the diagonals of an isosceles trapezoid are equal.

So, we have:

[tex]EG = FH[/tex]

This gives

[tex]3y + 19 = 11y - 21[/tex]

Collect like terms

[tex]11y - 3y =19 + 21[/tex]

[tex]8y = 40[/tex]

Divide through by 8

[tex]y = 5[/tex]

Hence, the values of x and y are 12 and 5, respectively

Step-by-step explanation:

To find area (I'm assuming a rectangle since you didn't specify)  All you need to do is multiply the two to find area.

Answer:

A: 26 People

B: There will not be any ice cream left over.

Step-by-step explanation:

Since you're serving in 3/4, its best to convert [tex]19\frac{1}{2}[/tex] to quarters, which is equal to [tex]\frac{78}{4}[/tex]. You can divide [tex]78/4[/tex] pints of ice cream by [tex]3/4[/tex] pints per person, which will get you 26 with no remainder. Since there is no remainder, there is no ice cream left over.

Step-by-step explanation:

Answer: Samples A and B have the same mean, but Sample A has a larger median then Sample B.

Step-by-step explanation:

The median is the middle number in the sequence.

To find the median, place the numbers in order. Then take away, or cross out, one number from each side. Keep going until you are down to one or two numbers. If there is only one number left, that’s your median. If two, add the numbers together and divide by 2.

The mean is the average. To get the mean you add up all the values and subtract that sum by how many numbers there are in the sequence.

Option D is correct for the given conditions, Samples A and B have the same mean, but Sample A has a larger median than Sample B.

The descriptive summary of a data set is known as the central tendency in statistics. It reflects the center of the data distribution through the use of a single number from the dataset. Additionally, it only provides a summary of the dataset rather than information on specific data within the dataset. In general, several statistical metrics can be used to determine a dataset's central tendency.

Given  the data sets of two sets of quiz scores,

Sample A = 5, 5, 5, 5, 5

sample B = 2, 2, 2, 2, 17

mean is the average of total samples,

mean of sample A = (5 + 5+ 5 + 5 + 5 )/5

mean of sample A = 5

Mean of sample B = (2 + 2 + 2+ 2 + 17)/5

mean of sample B = 5

since the mean of both sample are same,

median is the central digit of sets

median of A is 5 and the median of B is 2,

so the median of sample A is larger than sample B.

Hence option D is correct.

Answer:

The distance between them after 30 minutes is 6.5 km.

Step-by-step explanation:

Speed = [tex]\frac{distance}{time}[/tex]

Sarah's speed = 6 km/hr = 1.6667 m/s

Emily's speed = 10 km/hr = 2.7778 m/s

The measure of angle between their bearings = [tex]105^{o}[/tex]

After 30 minutes (1800 seconds);

distance = speed x time

Sarah would have covered a distance = 1.6667 x 1800

                               = 3000 m

                               = 3 km

Emily would have covered a distance = 2.7778 x 1800

                               = 5000 m

                               = 5 km

The distance between them, a, can be determined by applying the cosine rule;

[tex]a^{2}[/tex] = [tex]b^{2}[/tex] + [tex]c^{2}[/tex] - 2bcCos A

   = [tex]5000^{2}[/tex] + [tex]3000^{2}[/tex] -2(5000 x 3000) Cos 105

   = [tex]5000^{2}[/tex] + [tex]3000^{2}[/tex] -2(5000 x 3000) x (-0.2588)

   = 2.5 x [tex]10^{7}[/tex] + 9 x [tex]10^{6}[/tex] + 7764000

   = 41764000

a = [tex]\sqrt{41764000}[/tex]

  = 6462.5073

a = 6462.5 m

The distance between them after 30 minutes is 6.5 km.
