Answer:
20 ways
Step-by-step explanation:
by using combination rule :
6C3 = 6! /(3! × 3!)
= 6×5×4×3! / 3! × 3×2×1
= 20 ways

Explanation:
Order matters because we want to distinguish between first place, second place, and third place winners. So something like ABC is different from BCA.
We have 6 ways to pick a first place winner, then 5 for second place, then 4 for third place. Overall, there are 6*5*4 = 30*4 = 120 permutations
You could use the nPr formula with n = 6 and r = 3 as an alternative method

The spread of a rumor in a town can be modeled as , where N is the number of people who have heard of the rumor, and t is time (in days). How long will it take until 2000 people know about the rumor?
Answer:
the time is 16 days
Step-by-step explanation:
The computation of the time period is given below:
N = 500 √t
2000 = 500 √t
√t = 4
Now do the square on both the sides
SO,
t = 16
Hence, the time is 16 days
We simply applied the above method to determine the time period

Leave no cells blank. Enter 0 as an answer if undefined.)
Answer:
Kindly check explanation
Step-by-step explanation:
Given :
A.)
Vehicle speeds on highway (9 vehicles) 74, 82, 67, 73, 65, 41, 74, 49, 85
Ordered data :
41, 49, 65, 67, 73, 74, 74, 82, 85
Sample size, n = 9
Median = 1/2 * (n +1) th term
Median = 1/2 * 10 = 5th term
Median value = 73
Midrange = (Maximum + minimum) / 2
Midrange = (85 + 41) / 2 = 126 / 2 = 63
Geometric mean : √(x1*x2*.. xn)^1/n
Geometric Mean:
(41*49*65*67*73*74*74*82*85)^1/n
= 66.19
B.)
Sodium grams in canned soup (8 varieties)
X = 4.22, 3.60, 2.68, 2.75, 2.70, 4.17, 2.72, 4.29
Ordered data:
2.68, 2.70, 2.72, 2.75, 3.60, 4.17, 4.22, 4.29
Sample size, n = 8
Median = 1/2 * (n +1) th term
Median = 1/2 * 9 = 4.5th term
Median value = (2.75+ 3.6) / 2 = 3.175
Midrange = (Maximum + minimum) / 2
Midrange = (4.29 + 2.68) / 2 = 3.485
Geometric mean : √(x1*x2*.. xn)^1/n
Geometric Mean:
(2.68*2.70*2.72*2.75*3.60*4.17*4.22*4.29)^1/8
= 3.32
C.)
Campus health center visits (12 students)
X : 1, 5, 6, 13, 2, 3, 1, 3, 3, 1, 4, 3
Ordered data :
1, 1, 1, 2, 3, 3, 3, 3, 4, 5, 6, 13
Sample size, n = 12
Median = 1/2 * (n +1) th term
Median = 1/2 * 13 = 6.5th term
Median value = 3
Midrange = (Maximum + minimum) / 2
Midrange = (1 + 13) / 2 = 7
Geometric mean : √(x1*x2*.. xn)^1/n
Geometric Mean:
(1*1*1*2* 3*3*3*3*4* 5*6*13)^1/12
= 2.82

A personnel psychologist studying adjustment to the job of new employees found a correlation of .3 between amount of education and rating by job supervisors 2 months later. The psychologist now plans to use the amount of education to predict supervisors’ later ratings. Indicate the independent/predictor variable, dependent/criterion variable, and beta. Write the Z-score prediction model; give the predicted Z-scores for supervisor ratings for employees with the amount of education Z-score of -1.5, -1, -.5
Answer:
the predictor variable is: amount of education
the criterion variable is: the Supervisors' rating
the beta is: .3
the Zy scores are -0.45, -0.3, 0.15
Step-by-step explanation:
r=beta which is the same; hence correlation equals regression
use this formula for the Z-scores
Zy= (beta) (Zx)
zy=(.3) (-1.5) = -0.45
(E) -1.5;
Zy=-0.45
(F)-1,
Zy=-0.3
(G)-.5.
Zy=-0.15
Write the equation in slope-intercept form. -10x+2y=12
-please help
Answer:
y=5x+6
hope this helps
have a good day :)
Step-by-step explanation:
The slope intercept form for the equation -10x+2y=12 is y= 6+5x
What is slope- intercept form?The slope intercept form is a method used to determine the equation of a straight line in the coordinate plane. The equation of a straight line will be that relation which:
the coordinates of any point on the line must satisfy.the coordinates of any point not on the line will not satisfy.The determination of this equation is straightforward. To find the slope intercept form of a straight line, we would need the slope, or the angle of inclination of this straight line from the x-axis and the intercept that it makes with the y-axis.
Given:
-10x+2y=12
As, we know the slope- intercept form is
y= mx +b
Then writing the equation as the slope intercept form
-10x+2y=12
2y = 12 +10x
Divide both side by 2 to make the coefficient as 1.
y= 12/2 + 10x/2
y= 6 + 5x
Hence, the slope intercept form is y= 6+5x

Answer:
Length of Line AC = 26 units
Step-by-step explanation:
Given:
Line AC = [3x + 1] + 8
Line BC = [x - 2] + 2
Find:
Length of Line AC
Computation:
Line AB ║ Line L
So,
Using Mid-Point theorem;
[3x + 1] / 8 = [x - 2] / 2
2[3x + 1] = 8[x - 2]
6x + 2 = 8x - 16
8x - 6x = 16 + 2
2x = 18
x = 9
So,
Line AC = [3x + 1] + 8
Line AC = [3(9) + 1] + 8
Line AC = [27 + 1] + 8
Line AC = 28 + 8
Length of Line AC = 26 units

A. 8100
B. 10,400
C. 12,200
Answer:
A. 8100
Step-by-step explanation:
85 x 86
To estimate, we multiply 85*100, which is the easiest multiplication, as a multiplication by 100 is the same as placing two zeros at the end of the number.
85*100 = 8500
Since 86 < 100, 85*86 < 8500. Thus, the correct estimate is given by option A.
