The probability that a student is selected ta random is a man or received an A in the exam is 0.5714.
Step-by-step explanation:
In a class of 35 students there are 20 women and 15 men.
Compute the probability of selecting a men as follows:
Compute the probability of selecting a women as follows:
It is provided that 5 women and 4 men received A’s in the first exam.
Compute the probability of a a student getting an A and the student being a man as follows:
Compute the probability of a a student getting an A and the student being a woman as follows:
Compute the probability of a student receiving an A as follows:
Compute the probability that a student is selected ta random is a man or received an A in the exam as follows:
Thus, the probability that a student is selected ta random is a man or received an A in the exam is 0.5714.
Answer:
The number of rides they go on is of $ 20.50
Step-by-step explanation:
Given as :
The total amount both have = $ 25
The cost of mission fair = $ 4
The cost of try = $ 1.50
SO, the total amount spent = $ 4 + $ 1.50 = $ 5.50
So Left amount = $ 25 - $ 5.50 = $ 20.50
So, The number of rides they go on is of $ 20.50
Answer:
b.
Step-by-step explanation:
Quadratic equations are suppose to be written as:
so the new quadratic equation for this problem will be:
Now rearrange the terms:
Then use the Quadratic Formula to Solve for the Quadratic Equation
Quadratic Formula =
Note: Ignore the A in the quadratic formula
Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.
a = 3
b = -7
c = -1
