Answer: 5458
Step-by-step explanation: So the mean is the same thing as the average. To find the mean you add up all of the numbers, and then divide by 5 because there are five numbers. So the sum would be 27,290. Then that divided by 5 would be 5458.
The mean of the scores 3810, 5300, 8540, 4300 and 5340 is, 5466.
What is mean?Mean is an average of values of a set. Arithmetic mean, geometric mean and harmonic mean are the type of mean.
The given scores are
3810, 5300, 8540, 4300, 5340
Total number of terms is 5.
To find the mean, use formula,
Mean = sum of terms/number of terms.
Mean = (3810+5300+8540+4300+5340)/5
= 27330/5
= 5466
Mean of the given score is, 5466.

The probability that the photo also has a pet is 0.17
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
We are given that recent survey has shown that 68% of professional photos are of humans, 39% are of pets, and 17% are of both humans and pets.
We need to find the probability that the photo also has a pet.
Therefore,
P(a pet) = 39% = 0.39
P(humans) = 68% = 0.68
P(both humans and pets) = 17% = 0.17
This gives;
P(the photo also has a pet) = 0.17
The probability that the photo also has a pet is 0.17

Which equation could generate the curve in the graph below?
On a coordinate plane, a parabola opens down. The parabola is in quadrants 2 and 3, and has its vertex in quadrant 2.
y = –2x2 + 3x – 5
y = –2x2 – 4x – 2
y = –2x2 – 16x– 28
y = –2x2 +16x –28
Answer:
Its C boys
Step-by-step explanation:
I graphed all of them and compared
The equation that could represent the graph of the parabola is (c) [tex]y = -2x^2 - 16x- 28[/tex]
From the question, we have the following highlights
The parabola opens downThe vertex is in the second quadrantThe second highlight above means that:
The x coordinate (h) of the vertex is negative, while the y-coordinate (k) is positive.
For a parabola: [tex]y = ax^2 + bx + c[/tex], the vertex is:
[tex](h,k) = (-\frac{b}{2a},f(h))[/tex]
Next, we test the options
(a) y = –2x2 + 3x – 5
We have:
[tex]h = -\frac{3}{-2 \times 2}[/tex]
[tex]h = 0.75[/tex]
The value of h is positive.
So, this cannot represent the parabola
(b) y = –2x2 – 4x – 2
We have:
[tex]h = -\frac{-4}{-2\times 2}[/tex]
[tex]h = -1[/tex]
Substitute -1 for x in the function
[tex]k = -2x^2 - 4x - 2[/tex]
[tex]k = -2(-1)^2 - 4(-1) - 2[/tex]
[tex]k = 0[/tex]
The value of k cannot be 0
So, this cannot represent the parabola
(c) y = –2x2 – 16x– 28
We have:
[tex]h = -\frac{-16}{-2\times 2}[/tex]
[tex]h = -4[/tex]
Substitute -4 for x in the function
[tex]k = -2x^2 - 16x- 28[/tex]
[tex]k = -2(-4)^2 - 16(-4)- 28[/tex]
[tex]k=4[/tex]
The x coordinate (h) of the vertex is negative, while the y-coordinate (k) is positive.
Hence, [tex]y = -2x^2 - 16x- 28[/tex] could represent the parabola

Determine the unique weights of the juvenile
From the question, we understand that the weights of the juveniles could be any of 5 pounds, 6, 10 or 13 pounds
These values are the unique weights of the juveniles.
In other words, any value other than 5, 6, 10 or 13 can not be regarded as weights of the juveniles.

If line QN bisects angle PQR and N is the midpoint of line PR classify each triangle by its angles and sides
Answer:
The answer is "Equiangular, Equilateral"
Step-by-step explanation:
please find the complete question in the file.
In this question, the answer is equiangular, in which the triangle was considered an equilateral triangle with 3 parallel inner angles. It's the measurement of each of these interior angles is 60 degrees, inside an equiangular triangle, and although there 3 parallel sides of an equiangular triangle, so it is just like an equilateral triangle.
Based on the sides and angles of a triangle, triangle PQR would be classified as: an equilateral triangle.
Recall:
An equilateral triangle all three sides that are congruent and also has all of its three interior angles equal to 60 degrees each.In the diagram given (see image attached below), we have the following:
PQ = RQ = 14 (congruent sides)
PN = NR = 7 (N is the midpoint of PR)
Therefore:
PR = PN + NR
SubstitutePR = 7 + 7 = 14
This shows that triangle PQR has equal side lengths measuring 14 units (PQ = RQ = PR = 14).
Also, we are given that:m<QPR = m<QRP = 60 degrees (two congruent angles).
Taking right triangle QNR into consideration,m<NQR = 180 - (90 + 60) (sum of triangle)
m<NQR = 30 degrees
Therefore:
m<PQR = m<NQR + m<PQN
Substitutem<PQR = 30 + 30
m<PQR = 60 degrees.
This means that, triangle PQR has three equal angles measuring 60 degrees each (<PQR = <QPR = <QRP = 60 degrees).
Therefore, based on the sides and angles of a triangle, triangle PQR would be classified as: an equilateral triangle.
