Find the missing side or angle.
Round to the nearest tenth.
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

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

Answer:
(a) 18.5ft
(b) 388.5 ft²
Step-by-step explanation:
(a)
She has 79ft of fence = the perimeter will be 79.
Perimeter of a rectangle = 2(length) +2(width)
79 = 2(21)+2(width)
2(width) = 79 - 42
width = 37/2
width = 18.5ft
(b)
Area of a rectangle = (length)(width) = (21)(18.5) = 388.5 ft²
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
Marcia is mixing lemonade. She use 3 parts water to 1 part syrup. If she has 9 parts water, how much syrup will she need to complete the mixture?
Answer:
if Marcia uses 9 parts water, that mean she will have to use 3 parts syrup
Step-by-step explanation:
this is ratios,
so to find out how many syrup she needs, you need to see how much she used water from the original recipe
so:
9 ÷ 3 = 3
so she multiplied three to get to nine, so we have to do the same to the syrup
_ ÷ 1 = 3
or:
3 × 1 = 3
so the answer is 3

Answer:
2.45 tons
Step-by-step explanation:
square root of the sum of each number squared
The option that is closest to the standard deviation of T will be B. 2.45 tons.
How to calculate the standard deviation?The standard deviation of T based on the information given will be calculated thus:
= ✓2² + ✓1² + ✓1²
= ✓4 + ✓1 + ✓1
= 2.45
In conclusion, the calculation shows that the option that is closest to the standard deviation of T will be 2.45 tons.

Select all that apply. A. Isosceles triangle B. Parallelogram C. Rectangle D. Right triangle E. Square F. Trapezoid
Answer:
The awnswer is b c and e
Step-by-step explanation:
I submmited it and got it right hope this helps :D
The shapes which have all the properties shown are C. Rectangle and E. Square.
What are Isosceles Triangles?Isosceles triangles are defined as the triangles for which two sides or two angles are equal to each other.
Given properties are,
At least 2 sides of equal length
2 pairs of parallel sides
At least 2 right angles
Since the property includes that 2 pairs of parallel sides, it must contain 4 sides in total.
So triangle can't be a possible shape.
Parallelogram can't also be possible since there are no right angles.
Only right trapezoids are possible since the other ones will not have al least two right angles.
Rectangle and square are possible.
Hence the correct shapes are Rectangle and Square.

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).
