For the given set, the average is 13.5 years, and the standard deviation is 17.02 years.
What is the average age of the bears?
Here we know that the ages of the bears are {5, 4, 6, 39}, then the average of these 4 values is:
[tex]A = \frac{5 + 4 + 6 + 39}{4} = 13.5[/tex]
So the average age of the bears is 13.5 years.
What is the standard deviation?The standard deviation for the given set will be:
[tex]S_X = \sqrt{\frac{(5 - 13.5)^2 + (4 - 13.5)^2 + (6 - 13.5)^2 + (39 - 13.5)^2}{4 - 1} } \\\\S_X = 17.02[/tex]
The standard deviation is 17.02 years.

Charlie and Leo were playing with toy cars. Charlie said to Leo that if you give me one car, then i will have twice as many cars as you have. Leo said if charlie gives him a car, they will be equal. How many cars does each boy have?
Answer:
Charlie has 6 and Leo has 4
Step-by-step explanation:
6-1=5 and 4+1= 5
brainliest plsss
Answer:
In the beginning, Leo had 3 cars and Charlie had 3 cars.
In this problem, the statements seem to never be true if applied in the initial value. But if we take the value from the first statement and take it in the second, Leo and Charlie having 3 cars is true.
Step-by-step explanation:
Charlie said to Leo that if you give me one car, then i will have twice as many cars as you have.
[tex](L_{1} - 1) = 2L_{2} = C_{2}[/tex]
From that statement after Leo gives Charlie a car, we'll have something like:
Charlie's Leo's
2 1
4 2
6 3
Also, from that statement we can imply that we're not dealing with a great amount of cars, because the next statement won't be true.
Leo said if Charlie gives him a car, they will be equal.
[tex]L_{1}= C_{1} - 1[/tex]
Another thing is that if the second consideration holds true after the first statement. I will considerate that.
So,
In the beginning, Leo had 3 cars and Charlie had 3 cars.
In this problem, the statements seem to never be true if applied in the initial value.

Let the ratio of sharing between Stephen and Bridget be 4x and x
respectively .
According to the question ,
Stephen gets $27 more than Bridget.

of a circle.
What is the measure of the angle?
A
12°
30°
С
330°
D
360°
need help please
Answer:
Not widely used. If you continue to increase an angle it will eventually 'double back' on itself and form a full 360° angle. This is the Full Angle. One could argue that this is the same as a zero-sized angle. But we generally mean the reflex angle and so it is a full circle or 360°. Adjust the angle above and try to create the full angle going around in both directions.

If p(x) is a quadratic function and p(-1) = p(7) = 2,
which of the following could be the coordinates of
the vertex of the parabola formed when y = p(x) is
graphed in the xy-plane?
PLEASE EXPLAIN- I really don’t know:,)
(0,8)
(4,3)
(6,7)
(3,9)
Answer:
3,9
Step-by-step explanation:
hint: quadratic function
the form can be x² or x²+b or x²+bx+c
when p(-1)= 2 it means if we take x-axis = -1 the result (y-axis) will be 2. Same thing happen if we take x = 7
the vertex will always in the middle. So the middle of x = -1 and x = 7 is 3
-1, 0, 1, 2, 3, 4, 5, 6, 7
the vertex will occured when x = 3
the only answer with x = 3 is the fourth one (3,9)

B. R and S

Step-by-step explanation:
What are the solutions to the quadratic equation x2 – 16 = 0?
O x = 2 and x = -2
x = 4 and x = -4
x = 8 and x = -8
x = 16 and x = -16
Answer: x=8 and x=-8
Step-by-step explanation:
To find the solutions of the quadratic equation, you want to factor it and set it equal to 0.
x²-16=0
(x+8)(x-8)=0
x+8=0
x=-8
x-8=0
x=8
Now that we have factored and set the factors equal to 0, we found that the solutions are x=-8 and x=8.
It takes 160 ribbons to make 4 football mums. What is the constant of proportionality that relates the number of football mums made, y, to the number of ribbons used, x? 40 140 80 14
Answer:
40
Step-by-step explanation:
If two variable y and x are related to one other
then they can be represented as y = kx.
where k is constant of proportionality
Number of football mums is represented by y
and number of ribbons is represented by x
Then y = kx
Also, It takes 160 ribbons to make 4 football mums
substituting y with 4 and
substituting x with 160 in y = kx, we have
4 = k*160
=> k = 4/160 = 1/40
Thus, constant of proportionality is 1/40.
But here option given are 40 140 80 14
so ,equation can be represented as
x = ky
substituting y with 4 and
substituting x with 160 in x = ky , we have
160 = k*4
=> k = 160/4 = 40
Thus, for equation x = ky , constant of proportionality is 40.

Denice had 236 yellow stars and 196 blue stars. She wants to arrange them in rows of 4. How many rows of stars would Denice have?
Answer:
108
Step-by-step explanation:
236 + 196 = 432 (total stars)
432 / 4 = 108 rows.
Answer:
108 rows.
Step-by-step explanation:
236 stars + 196 stars = 432 stars in total
So if you're putting 432 stars in 4 rows, you have to divide 432/4, which equals 108 rows with 4 stars in each row.

Two bottles of water and three small bags of fruit cost a total of £2.55. If a bottle of water costs 15p more than a bag of fruit, what is the cost of a bag of fruit?
Answer:
45p
Step-by-step explanation:
2w+3f=2.55
w=f+15p
2w=2f+30p
2f+3f+30p=2.55L
5f+30p=255p
5f=255-30

1. Mr. Smith visited the park one sunny afternoon. He noticed that only
dogs and people were in the park that day. While he was resting on a park
bench, he observed that there were 15 heads and 50 legs in the park.
Which pair of system of equations can be used to determine the number
of dogs and the number of people in the park that day (use x = # of people;
y = # of dogs)?
x + y = 50: 2x + 4y = 15
x + y = 15, 4x + 2y = 50
X + y = 15:2x + 4y = 50
x + y = 50; 4x + 2y = 15
Answer:
x+y=15 ; 2x+4y=50
Step-by-step explanation:
Let x be the number of people
Let y be the number of dogs.
Equation regarding Total Heads:Total number of heads = 15
As
1 person has 1 head
1 dog has 1 head
Total no. of heads of people = 1 * x = x
Total number of heads of dogs = 1*y = y
Equation becomes:
x+y=15
Equation regarding Total Legs:Total number of legs = 50
As
1 person has 2 legs
1 dog has 4 legs
Total no. of legs of people = 2 * x = 2x
Total number of legs of dogs = 4*y = 4y
Equation becomes:
2x+4y=50
