Answer:
4. A cluster tells you where there is a concentration of data values.
Step-by-step explanation:
makes the most sense
A cluster tells you where there is a concentration of data values. The correct answer would be an option (C).
What is the Scatter plot?The variables in the scatter plot made from the data are described by the independent variable, time, which is graphed along the horizontal axis.
A cluster on a scatter plot refers to a group of points that are closely located together. This indicates that there is a concentration of data values in that area of the plot, as opposed to being spread out evenly. This cluster can be seen visually as a group of points that are tightly packed together.
Thus, a cluster tells you where there is a concentration of data values.
Hence, the correct answer would be option (C).

A spherical ball has a diameter of 8 inches. The ball has a slow leak in which the air escapes at the rate of 2.5 inches per second. How long would it take for the ball to deflate? Round to the nearest tenth.
Answer:
107.2 seconds
Step-by-step explanation:
Step one:
given
the diameter of ball 8 inches
radius= 8/2 = 4 in
The volume of the ball
[tex]v=4/3 \pi r^3[/tex]
[tex]v= 4/3*3.142*4^3\\\\v= 4/3*3.142*64\\\\v= 804.35/3\\\\v=268.12 in^3[/tex]
Step two:
we know that
rate= quantity/time
rate= 2.4 in per second
quantity= 268.12
time=?
time= quantity/rate
time= 268.12/2.5
time= 107.2 seconds

how many combinations of 3 letters can be made from the word oranges ? what is the probability that these three letters will all be consonants?
The number of all possible combinations of 3 letters can be made from the word 'oranges' = 35
The probability that the three letters will be consonants = 0.114
In this question, we have been given a word 'oranges'
We need to find the number of ways in which the letters of orange can be arranged.
Also, we need to find the probability that these three letters will all be consonants.
The number of letters in the word oranges = 7
So, n = 7
We need combinations of 3 letters.
so, r = 3
The number of all possible combinations of 3 letters would be,
^7C_3 = 7! / (7 - 3)! (3!)
^7C_3 = 35
The number of combinations of 3 letters = 35
We can observe that the consonants in the word 'oranges' are:
r, n, g, s
The number of consonants = 4
The combinations of 3 consonants would be,
^4C_3 = 4! / (4 - 3)! 3!
^4C_3 = 4
The required probability would be,
p = ^4C_3 / ^7C_3
p = 4 / 35
p = 0.114
Therefore, the number of all possible combinations of 3 letters can be made from the word 'oranges' = 35
the probability that the three letters will be consonants = 0.114

A hairstylist charges $15 for an adult haircut at nine dollars for a child haircut she wants to earn at least $360 and cut a maximum of 30 haircut this week the graph represents the hairstylist constraints
Answer:10 adult and 20 children
Step-by-step explanation:
The two inequalities for the given situation are x+y>30 and 15x+9y≤360.
Given that, a hairstylist charges $15 for an adult haircut at nine dollars for a child haircut she wants to earn at least $360.
What is a inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Let the number of adults be x and the number of child be y.
So, x+y>30
Now, 15x+9y≤360
⇒ 3(5x+3y)≤360
⇒ (5x+3y)≤120
From the graph we can see that, two graphs intersecting at (15, 15)
Therefore, the two inequalities for the given situation are x+y>30 and 15x+9y≤360.

Which of the following is equivalent to the complex number i^16?
Answer:
A
Step-by-step explanation
i = [tex]\sqrt{-1}[/tex]

i³ = i² × i = - 1 × i = - i
[tex]i^{4}[/tex] = i² × i² = - 1 × - 1 = 1 , then

Which statement best illustrates using the vertical line test to determine if the graph below is a function of x?
A. The graph is not a function of x because the line x = 0 intersects the graph at two points.
B. The graph is a function of x because the line x = 5 does not intersect the graph.
C. The graph is not a function of x because the line y = 0 intersects the graph at two points.
D. The graph is a function of x because the line y = 5 does not intersect the graph.
Answer:
A
Step-by-step explanation:
Graph is not a function, so B and D are false.
y = 0 is a horizontal line, not a vertical line, so C is false.
This leaves only A.
find the value of 7w+9 given that -4w -4=4
can someone please help!! it would mean the world to me:) i fave finals tomorrow
Answer:
w= -1/3
Let's solve your equation step-by-step.
7w+9−4w−4=4
Step 1: Simplify both sides of the equation.
7w+9−4w−4=4
7w+9+−4w+−4=4
(7w+−4w)+(9+−4)=4(Combine Like Terms)
3w+5=4
3w+5=4
Step 2: Subtract 5 from both sides.
3w+5−5=4−5
3w=−1
Step 3: Divide both sides by 3.
3w/3=−1/3
w= −1/3
Answer:
w= −1/3
