Consider such events:
A - selected student is freshmen
B - selected student is girl
- selected student is freshman is girl
- choosen girl is freshmen.
Use formula 
.
From the table you can see that girls that are freshmen are 4 from all 30 people, then 
. There are 18 girls, then 
. Substitute into the formula:
.
Answer: 
.
With scientific notation remember this rule; if the exponent is positive, move the decimal point that many places to the right. If it is negative move it that many places to the left. What that will do is make the number larger or smaller to the correct value.
So for example, if you had to solve 1.02 x 10^4 you would move the decimal four places to the right. So you would end up with 10200.
As another example if you had to solve 1.02 x 10^-2 you would move the decimal two places to the left. That would give you .0120.
So now we are onto your problem. 2.606 x 10^7.
You would move the decimal seven places to the right, because the exponent is positive, that will make your number larger(which would make more sense if you were adding populations, right?).
That would give you 26,060,000 people living in Texas.
From there simply add the two populations together and you will have your answer!
I hope this helps you
3.t^2.square root of 7
Step-by-step explanation:
first you have to see the triangle BCD
then hypotheses and perpendicular are given so you have to find base
after finding base. In rectangle ABCD DC is length and BC is breadth so now you can find area by using the formula A = l×b
Answer:
