Probability 1st song is sung by female : 55/100 reduces to 11/20
probability 2nd song is sung by a male : 35/100 reduces to 7/20
probability 3rd song is instrumental : 10/100 reduces to 1/10
probability of all 3 events happening : 11/20 * 7/20 * 1/10 = 77/4000
Answer: (10/3)
Explanation:
(4/3)/(2/5) = (10/3)
Multiply by reciprocal
And solve
Answer:
Step-by-step explanation:
hello :
The expression 1/2mv^2
M=1.6x10^3
V=3.4x10^3
is : 1/2(1.6x10^3 )(3.4x10^3)²=2.72x 10^9
Answer:
A. 1/2 of a goal
Step-by-step explanation:
Hello!
Given the options:
A. 1/2 of a goal
B. 3/4of a goal
C. 1 goal
D. 4/3 goals
In a linear regression analysis the interpretation of the slope is:
> The modification of the average of Y when X increases one unit.
Given the variables
Y: Goals scored in the tournament.
X: Hours of training.
To calculate the slope, you have to use the y-intercept and choose two pairs of (Y;X) values that correspond to a value on the line, for example (1;1.5) and (2;1.5).
You can calculate the slope as b= ΔY/ΔX

1st value (X₁;Y₁)= (0;1)
2nd value (X₂Y₂)= (1;1.5)
So the average goals a player scores for every additional hour of practice is 1/2.
I hope this helps!
