An adult ticket for a musical cost $12. A children's ticket for the musical cost $4. The number of adult tickets sold is 4 times the number of children's tickets sold. A total of 1560 is taken in for ticket sales.
1. 160 adult tickets and 40 children's tickets
2. 120 adult tickets and 30 children's tickets
3. 40 adult tickets and 160 children's tickets
4. 30 adult tickets and 120 children's tickets
Answer:
B
Step-by-step explanation:
multiple 12 and 120 which is 1,440 then multiply 4 and 30 which is 120 and add it up which comes to 1,560. HOPE THIS HELP!!!
The total number of adults tickets sold and children tickets sold is 120 adult tickets and 30 children's tickets
Given:
Cost of adult tickets = $12
Cost of children tickets = $4
let
number of children tickets sold = x
number of adult tickets = 4x
Total cost of tickets = 1560
The equation:
1560 = 12(4x) + 4(x)
1560 = 48x + 4x
1560 = 52x
divide both sides by 52
x= 1560/52
x = 30
Therefore,
number of children tickets sold = x
= 30 tickets
number of adult tickets = 4x
= 4(30)
= 120 tickets

What is the type of correlation for the plot?
answer the following correctly
Answer:
[tex] y = -\frac{10}{3}x - 23 [/tex]
Step-by-step explanation:
Find slope (m) using of the line that passes through (-9, 7) and (-6, -3).
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-3 - 7}{-6 -(-9)} = \frac{-10}{3} = -\frac{10}{3} [/tex]
Find y-intercept (b) by substituting m = -10/3, x = -6, and y = -3 in y = mx + b.
Thus:
-3 = (-10/3)(-6) + b
-3 = 20 + b
Subtract 20 from each side
-23 = b
b = -23
substitute m = -10/3, and b = -23 in y = mx + b, to get the equation.
The equation of the line would be:
✅ [tex] y = -\frac{10}{3}x + (-23) [/tex]
[tex] y = -\frac{10}{3}x - 23 [/tex]

Find the measure of one exterior angle of a regular octagon
Answer:
each of the eight angles measures 45 degrees
Step-by-step explanation:
The sum of all exterior angles of any polygon always measures 360 degrees.
If it's 'regular' then all angles have the same measures.
If it's an octagon, then it has 8 sides.
360 divided by 8 = 45

Your answer would be B: 30 ft squared
Step-by-step explanation:
Find the area of the circle: 5.5 (radius) multiply it by itself then multiply that by 3.14 which gets you 94.985. Now find the area of the square which is 8*8 = 64. Subtract 64 from 94.985 and your answer will be 30.985. The questions asks for the approximate (estimate), so the closest one would be 30 ft squared

if the probability of picking a pink jelly bean out of a bag is 4/15, what is the probability of not picking a pink jelly bean
Answer:
The probability of not picking a pink jelly bean: 11/15
Step-by-step explanation:
As we know that the maximum value of the probability of an event would always be 1.
The reason is that '1' is certain that something would happen.Given that the probability of picking a pink jelly bean out of a bag is 4/15.
Thus, the probability of not picking a pink jelly bean can be calculated by subtracting 4/15 from the maximum probability '1'.
i.e.
Probability of not picking a pink jelly bean = max probability - 4/15
= 1 - 4/15
= 11/15
Therefore, the probability of not picking a pink jelly bean: 11/15
what does x equal?
4x+7=31
Answer:
x = 6
Step-by-step explanation:
First, subtract 7 from both sides to get x alone. That will give you 4x = 24 .
Then divide both sides by 4 to remove the coefficient of x. That means x = 6.
4x+7=31
-7 -7
4x=24
÷4 ÷4
x = 6

Answer:
The value of AC = 5 units
Step-by-step explanation:
Given the triangles
ΔABCΔXYZIn the diagram,
ΔABC ~ ΔXYZWe know that two triangles are termed as similar if their corresponding angles are congruent and the corresponding sides are in proportion.
Therefore,
AB : XY = AC : XZ
AB / XY = AC / XZ
as
AB = 4XY = 6XZ = 7.5AC = ?so we can determine AC as the ratios of the side become
4 / 6 = AC / 7.5
AC = 4/6 × 7.5
= 5 units
Therefore, the value of AC = 5 units
Write equations for the vertical and horizontal lines passing through the point (0, -3).
Answer:
Vertical line will be x=0, and horizontal line will be y=-3
Step-by-step explanation:
Draw a vertical line through point (0,-3). You will see it's on the y-axis. The equation of the line on y-axis is always x=0, because no matter what point you choose on the line, the x coordinate will be 0. (0,-3), (0, -2), etc.
Next draw a horizontal line through (0,-3). It's parallel to the x axis, and no matter what point on the line you choose, the y coordinate will be -3. (0,-3), (1, -3), etc
The equation for the vertical line is x=8 and the horizontal line is y=−7.
The given coordinate point is (0, -3).
What are the vertical and horizontal lines?A vertical line is a line, parallel to the y-axis and goes straight, up and down, in a coordinate plane. Whereas the horizontal line is parallel to the x-axis and goes straight, left and right.
Now,
For a vertical line the value of x, in this case, 8, will never change. This will be true for any value of y. Therefore the equation for a vertical line passing through this point is: x=8
Likewise, for a horizontal line the value of y, in this case, −7, will never change. This will be true for any value of x. Therefore the equation for a horizontal line passing through this point is: y=−7
Therefore, the equation for the vertical line is x=8 and the horizontal line is y=−7.

There are 125 people on a mountain trail. If 84% of the people on the trail are on a hiking tour, how many people are on the tour
Answer:
Total people on the tour will be: 105 people
Step-by-step explanation:
Total people on a mountain trail = 125Given that 84% of the people on the trail are on a hiking tour.
We need to determine how many people are on the tour.
All we need is to multiply 84% or 0.84 by 125.i.e.
People are on the tour = 84% × 125
= 84/100 × 125
= 0.84 × 125
= 105 people
Therefore, total people on the tour will be: 105 people

Complete Question
How large a sample is needed if we wish to be 96% confident that our sample proportion in Exercise 9.53 will be within 0.02 of the true fraction of the voting population?
Exercise 9.53
A. A random sample of 200 voters in a town is selected, and 114 are found to support an annexation suit. Find the 96% confidence interval for the fraction of the voting population favoring the suit.
B. What can we assert with 96% confidence about the possible size of our error if we estimate the fraction of voters favoring the annexation suit to be 0.57?
Answer:
The First question
[tex] n = 1879 [/tex]
A
The 96% confidence interval is
[tex]0.51 < p < 0.63 [/tex]
B
The possible size of our error if we estimate the fraction of voters favoring the annexation suit to be 0.57 is
[tex]E = 0.06 [/tex]
Step-by-step explanation:
From the question we are told that
The margin of error is [tex]E = 0.02[/tex]
The sample size is n = 200
The number that supported the annexation suit is k = 114
Considering the first question
Generally our sample in Exercise 9.53 is [tex]\^ p = 0.57[/tex]
From the question we are told the confidence level is 96% , hence the level of significance is
[tex]\alpha = (100 - 96 ) \%[/tex]
=> [tex]\alpha = 0.04[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.751 [/tex]
Generally the sample size is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]
=> [tex]n = [\frac{1.751}{0.02 } ]^2 * \^ p (1 - \^ p ) [/tex]
=> [tex]n = [\frac{1.751}{0.02 } ]^2 * 0.57 (1 -0.57 ) [/tex]
=> [tex] n = 1879 [/tex]
Considering question B
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]
=> [tex]E = 1.751 * \sqrt{\frac{ 0.57 (1- 0.57 )}{200} } [/tex]
=> [tex]E = 0.06 [/tex]
Considering question A
Generally the sample proportion of the number that supported the annexation suit is mathematically represented as
[tex]\^ p = \frac{114}{200}[/tex]
=> [tex]\^ p = 0.57[/tex]
Generally 96% confidence interval is mathematically represented as
[tex]\^ p -E < p < \^ p +E[/tex]
=> [tex]0.57 - 0.06 < p < 0.57 + 0.06 [/tex]
=> [tex]0.51 < p < 0.63 [/tex]
A plate moves 200 m in 10,000 years. What is its rate in cm/year? 0.02 cm/year 2 cm/year 10 cm/year 100 cm/year
Answer: 2cm/year
Step-by-step explanation:
1m = 100cm
200m = 20000cm
10,000years = 20,000cm
1 year = 20,000/10,000 = 2cm
It's rate is 2cm/year
Answer:
0.02 cm/year
Step-by-step explanation:
200m:10,000 years
10,000 divided by 10,000=1
200 divided by 10,000=0.02
