Answer:
5/ 19 ≈ 0.26 = 26%
Step-by-step explanation:
given: student is female. there is a 100% chance that the student is female
probability we want = (favorable outcomes) / (total outcomes)
total outcomes = 19 because there are 19 female students and the student must be female
favorable outcomes = 19 - 14 = 5 females who do not have an A in the class
probability = 5/ 19 ≈ 0.26 = 26%
Answer: x = -1
Step-by-step explanation:
You need to convert to the same base

So

For these values to be equal, the exponents have to be equal
-4 = -2x - 6
2 = -2x
x = -1
Answer:
4 + ( -7 X 2 ) = -10
Step-by-step explanation:
Check work:
-7 times 2 is -14.
4 + -14 = -10
Answer: 
Step-by-step explanation:
Pythagorean theorem:
, where a and b are the legs and c is the hypotenuse.
We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.


Since we don't know what
is, we're going to isolate it by subtracting 81 on both sides

We have to square root both sides in order to find out b (or x in the problem).

When you put this on a calculator it would result in
which is the answer d in the problem.
the time taken to get to your work place is 0.5 hour.
The given parameters;
- distance between your new job and your house = 25 miles
- speed to work, v = 50 mph
The time taken to get to work is obtained by dividing the distance between your new job and your house, by speed of your motion to work.
Distance = speed x time

Thus, the time taken to get to your work place is 0.5 hour.
