Answer:
the 4.49 ones.
Step-by-step explanation:
11.57 divided by 8 would result in each pen costing 1.44$ per pen. Meanwhile, dividing 4.49 by 4 would result in each pen costing 1.12$.
Answer: The second deal is cheaper
=========================================================
Explanation:
We're looking for the unit cost, which is the cost for one item (in this case, it's the cost of one pen). To get the unit cost, divide the total cost over the number of pens.
For the first deal, we have a unit cost of 11.57/8 = 1.44625 which rounds to 1.45 dollars.
The unit cost for the second deal is 4.49/4 = 1.1225 which rounds to 1.12 dollars. The second deal is the cheaper option due to 1.12 being smaller than 1.45

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:
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.

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

Provide the final answer as a fraction.
Answer:
1/2
Step-by-step explanation:
The probability that the advertisement is a social media ad and has an odd number is 1/13.
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Given that, A local business had various advertising campaigns. It had television ads numbered 1,2,3,4,5,6, newspaper and magazine ads numbered 1,2,3,4,5, and social media ads labeled 1,2.
We need to find If a single advertisement campaign is picked at random, what is the probability that the advertisement is a social media ad AND has an odd number,
Probability = favorable outcomes / possible outcomes
Number of social media ads with an odd number = 1
Total number of ads = 13
We know that,
P(that the advertisement is a social media ad AND has an odd number)
= 1/13.
Hence, the probability that the advertisement is a social media ad and has an odd number is 1/13

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
