Answer:
The probability that a student takes Spanish given that the student is taking Computer Programming = 0.375
Step-by-step explanation:
Given -
Let event A = student takes Spanish
Event B = student takes Computer Programming
= student takes Computer Programming and Spanish
P(B) = 0.4 , 
= 0.15
What is the probability that a student takes Spanish given that the student is taking Computer Programming =
(Probability of an event occuring given that another event has already occured , we use condition probability )
= 
= 0.375
Answer:
The value of x from the equation is 100. Thus, Mrs. Gleason should work for 100 hours per month.
Step-by-step explanation:
To answer this item, we let x be the number of hours per month that Mrs. Gleason should work. The total budget is equal to sum of the amount acquired by Mr. Gleason and Mrs. Gleason. The equation that would express this is,
4,500 = 900(4) + 9x
The value of x from the equation is 100. Thus, Mrs. Gleason should work for 100 hours per month.
I am sorry if you get this wrong.

Step-by-step explanation:
<u>Step 1: Define</u>
2(3x - 1) ≥ 4x - 6
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 2: 6x - 2 ≥ 4x - 6
- Subtract 4x on both sides: 2x - 2 ≥ -6
- Add 2 on both sides: 2x ≥ -4
- Divide 2 on both sides: x ≥ -2
Here we see that any value <em>x</em> greater than or equal to -2 would work as a solution.
