Answer:
The probability to the nearest thousandth is 0.386
Step-by-step explanation:
Firstly, we will need to know the number of girls and the total number of students in the class.
We have the ratio as 3:5 for boys and girls with the number of boys being 18
What we have is thus;
3:5 = 18:g
3/5 = 18/g
3g = 90
g = 90/3
g = 30 girls
Thus, we have 18 boys and 30 girls with a total of 48 students.
The probability that the teacher selects a girl to write the question on the board is 30/48 = 5/8
Now, we intend selecting another girl to answer the question. This is like a probability without replacement. So this means that the number of girls we have now is 29 and the number of students we are selecting from is 47 students
Thus, the probability of selecting a girl to answer the question becomes 29/47
The joint probability is thus; 29/47 * 5/8 = 145/376 = 0.3856
To the nearest thousandth, we have 0.386

Days : 1 2 3 4 →→→→→→D(X axis)
Rent a Truck: 34 50 66 82→→→→→→R(Y axis)
As you can observe from number of Days and Amount to rent a truck , if you rent for a day the price being $ 34 and with increase in Day the rent increases by $ 16.
Plotting the point on graph , found that these points are collinear.
So, we can Represent this relation between days and Rent in equation of two variables representing a line.
Two point formula of line:
→→Equation of line passing through two points
So , line representing Days and rent is :
So, the rule representing Days and Rent is: 16 D - R + 18=0

The answer is 18
If you subtract 47-29=18
Then if you subtract 47-65=18 the pattern is to add 18

Step-by-step explanation:
8x + 4 = 3x - 3 +7
u first expand the bracket as I have done above
then u evaluate those who have like terms close like -3 + 7
8x + 4 = 3x + 4
then u group like terms ie. the values with the variable x on one side of the equation and the ones without x on the other side of the equation
8x - 3x = 4 - 4
8x - 3x = 0
5x = 0
then u divide both side by the coefficient of x
0/5 but any number divided by 0 is 0, so x = 0
