A group consisting of 10 children an adult went to a movie theater children tickets cost 5 each and adults tickets cost 8 each and the total cost for 10 people was 62.how much children were in the group
9514 1404 393
Answer:
6 children
Step-by-step explanation:
If all of the group were adults, the total cost of tickets would be 8×$10 = $80. The actual cost was $80 -62 = $18 less than that. Since each children's ticket saves $3 off the cost of an adult ticket, there were $18/$3 = 6 children's tickets.
There were 6 children in the group.
_____
If you want an equation, you can let c represent the number of children. Then the cost of tickets is ...
8(10 -c) +5c = 62 . . . . 10-c is the number of adults
-3c = -18 . . . . . . . subtract 80
c = -18/-3 = 6 . . . divide by 3

suppose that a population parameter is 0.2, and many samples are taken from the population. As the size of each sample increases, the mean of the sample proportions would approach which of the following values?
A. 0.1
B. 0.3
C. 0.4
D. 0.2
Answer:
D 0.2
Step-by-step explanation:
YES THIS IS RIGHT
The required, mean of the sample proportions would approach is 0.2.
What is a normal distribution?Normal distributions can be altered to standard normal distributions by the formula:
Z = (X - μ)/σ
As the size of each sample increases, the mean of the sample proportions would approach the population parameter, which in this case is 0.2. This is known as the central limit theorem.
Therefore, the answer is D. 0.2.

Step-by-step explanation:
It's 3000*1.05=3150
3150*1.05=3,307.5
Answer:
3472.875
Step-by-step explanation:
5% of 3000 is 150, therefore he spent 3150 in 2018.
5% of 3150 is 157.50 therefore he spent 3307.50 in 2019
5% of 3307.50 is 165.375 therefore he spent 3472,875 in 2020

Determine the center and radius of the following circle equation: x^2+y^2+20x+8y+35=0
Answer:
center: (-10,-4)
radius: 9
Step-by-step explanation:
Let's start off by moving the 35 to the other side and grouping the x and y terms we have
(x²+20x)+(y²+8y)= -35
Next we take the term with the x coeficcent, divide it by 2, and square it
so
for the x we would do (20/2)²=100
and make sure we add that to the 35
(x²+20x+100)+(y²+8y+16)= -35+100+16
next factor everythign to get
(x+10)²+(y+4)²=81
therefore the center is (-10,-4)
and the radius is √81 or 9

13. Becky and Scott rode their bicycles to school. Becky rode 8 km in 15 min., while Scott rode 12 km in
25 min. Who rode faster? Justify your answer.
Step-by-step explanation:
Calculate their speed to see who rode faster.
Speed = Distance ÷ Time
Change the unit from minutes to hours so that the answers are in km/h.
Becky's speed
[tex] = 8 \div \frac{15}{60} [/tex]
[tex] = 8 \div 0.25[/tex]
= 32 km/h
Scott's speed
[tex] = 12 \div \frac{25}{60} [/tex]
[tex] = 12 \div 0.41666...[/tex]
= 28.8 km/h (rounded to the nearest tenth)
∵ 32 km/h > 28.8 km/h
∴ Becky rode faster.

C=53°
B= 80°
a=2
b=[?]
Answer:
2.69 approximately 3
Step-by-step explanation:
53⁰+80⁰+A=180⁰(sum of angles on a triangle)
133⁰+A=180
A=180-133
A=47⁰
using sine rule
2/sin 47 = b/sin 80
b sin47 = 2 sin 80
b= 1.9696/0.7314
b=2.69 approximately 3
Identify the distance between points (3,7,1) and (9,6,7), and identify the midpoint of the segment for which these are the endpoints. Round to the nearest tenth, if necessary.
Step-by-step explanation:
[tex]range = (3,7,1) - (9,6,7) \\ = ( - 6,1, - 6) \\ distance = \sqrt{ {x}^{2} + {y}^{2} + {z}^{2} } \\ = \sqrt{ {( - 6)}^{2} + {1}^{2} + {( - 6)}^{2} } \\ = \sqrt{73} \\ = 8.5 \: units[/tex]
The distance between points (3,7,1) and (9,6,7) is 8.54 units and the midpoint of the segment is (6, 6.5, 4).
What is Distance?The length along a line or line segment between two points on the line or line segment.
Distance=√(x₂-x₁)²+(y₂-y₁)²
We need to find the distance between points (3,7,1) and (9,6,7).
Distance=√(9-3)²+(6-7)²+(7-1)²
=√6²+(-1)²+(6)²
=√36+1+36
=√73
=8.54 units
So the distance between the two points is approximately 8.5 units.
To find the midpoint of the segment between the two points, we use the midpoint formula:
midpoint = ((x₁+x₂)/2, (y₁+y₂)/2, (z₁+z₂)/2)
Using the given points, we have:
midpoint = ((3+9)/2, (7+6)/2, (1+7)/2)
= (6, 6.5, 4)
So the midpoint of the segment is (6, 6.5, 4).
Hence, the distance between points (3,7,1) and (9,6,7) is 8.54 units and the midpoint of the segment is (6, 6.5, 4).

Aiden wants to make 1/2 of a batch of muffins the recipe calls for 2/3 cup of milk for whole batch how much milk should aiden use?
Answer:
Quantity of milk Aiden needs = 1/3 cup of milk
Step-by-step explanation:
Given:
Aiden wants to make muffins = 1/2 batch
Full batch muffins need = 2/3 cup of milk
Find:
Quantity of milk Aiden needs
Computation:
Quantity of milk Aiden needs = Number of batch Aiden make x Amount of milk need for a batch

Quantity of milk Aiden needs = 1/3 cup of milk
Which set of data has the smallest difference between the mean and the median?
O A 13, 42, 17, 26, 38
OB. 28, 7, 36, 8, 17
OC 14, 29, 38, 7, 13
OD 23, 36, 25, 38, 30
Answer:
D 23, 36, 25, 38, 30
Step-by-step explanation:
Mean of a data-set:
The mean of a data-set is the sum of all it's values divided by the number of values.
Median of a data-set:
The median of a data-set is the value that separates the lower 50% from the upper 50% on the ordered set.
If the cardinality n is odd, as in this case, the median is the element at the position (n+1)/2. Since in this case, n = 5, the median is the 3rd element in the ordered set.
A 13, 42, 17, 26, 38
Ordered set: 13, 17, 26, 38, 42
Median: 26
Mean: (13+17+26+38+42)/5 = 27.2
Difference: 27.2 - 26 = 1.2
B. 28, 7, 36, 8, 17
Ordered set: 7, 8, 17, 28, 36
Median: 17
Mean: (7+8+17+28+36)/5 = 19.2
Difference: 19.2 - 17 = 2.2
C 14, 29, 38, 7, 13
Ordered set: 7, 13, 14, 29, 38
Median: 14
Mean: (7+13+14+29+38)/5 = 20.2
Difference: 20.2 - 14 = 6.2
D 23, 36, 25, 38, 30
Ordered set: 23, 25, 30, 36, 38
Median: 30
Mean: (23+25+30+36+38)/5 = 30.4
Difference: 30.4 - 30 = 0.4
