Answer:
False
Step-by-step explanation:
The probability of it not having tail on the tenth flip is 1 (one) minus the probability of having tail ,and I'm this case we will be expecting a head.
Probability of a head = 1 - 0.5 =0.5.
In rewriting the statement as a true statement we will say 'The probability it will land heads up on the tenth flip is equal to 0.5'
Answer:
1/2*(x+1)[(6x+5)+(4x+7)}
Step-by-step explanation:
Step-by-step explanation:
y=kx
4=k*3,4=3k,4/3=k.to find y when X is 15 ,y=kx,y=4/3*15=60/3=20
Let x = the number of total students in the class
Convert the percent into a decimal by moving the percent sign two places to the left and change the percent sign into a decimal point.
60% = 0.6
Then 0.6x = the number of girls in the class
Then 0.6x + 30 = the total number of students in the class
0.6x + 30 = x
Solve for x.
0.6x + 30 = x
0.6x = x - 30 <-- Subtract both sides by 30
-0.4x = -30 <-- Subtract both sides by x
x = 75
Now we have the total number of students in the class.
60 percent of the students are female.
0.6 * 75 = 45
So, C 45 is the answer.
