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
The area of a rectangle is 200 square feet. Find its length if its width is 10 feet.
Answer:
20
Step-by-step explanation:
In area you have to multiply so 10 x ? = 200
10 x 20 = 200

Why 117+3 = 5! is correct
Answer:
5!= 5×4×3×2×1
117+3=120
5×4×3×2×1= 120
therefore 117+3=5! is correct
The statement 117+3 = 5! is correct because;
The left hand side and right hand side give the same solution of 120.
We want to find out why 117 + 3 = 5! is correct.
Let us first find the left hand side of the equation;
117 + 3 = 120
Now, for the right hand side, 5! simply means 5 factorial.
Factorial of a number is a term used in maths to denote the product of all
positive integers less than or equal to that number. For example; n!. That is
factorial and it means the product of all positive integers below n.
Let's apply the concept of factorial to 5!.
All positive integers less than or equal to 5 are; 5, 4 , 3, 2, 1
Thus; 5! = 5 × 4 × 3 × 2 × 1 = 120
This 5! = 120 and it is the same as 117 + 3 = 120. Thus the given statement in the question is true.

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.

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

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).

Hope it is helpful...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

Ordered set: 7, 8, 17, 28, 36
Median: 17
Mean: (7+8+17+28+36)/5 = 19.2
Difference: 19.2 - 17 = 2.2

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
