Answer:
d.) x/y
Step-by-step explanation:
quotient means to divide and d shows x & y getting divided
Step-by-step explanation:
4√2 + √2 = 5√2 we add 4 and the invisible 1 in front of √2, the common root stays same
8√3 - 4√3 = 4√3 subtract 4 from 8 the common root stays same
2√3 x √32 ➡ 2√3 x 4√3 too add the expressions we first need to make the roots common then add 4 and 2
If you add 55% and 45% the total is 100% so 45/100 are girls. 35% of the girls scored and A so 35/45 is the probability that it is a girl chosen or 7/9. the probability is 7 out of 9
Answer:
13. ABCD and DCBA
14. BA and CD
15. AB abd BC
16. The points B and L can be collinear.
Step-by-step explanation:
See the given diagram of a straight line that extends from -∞ to +∞.
13. ABCD and DCBA are the two different names of the line.
14. BA and CD are the names of different opposite rays.
15. AB and BC are the two line segments.
16. The line between points B and L can be drawn separately. So, the points B and L can be collinear. (Answer)
Remark
There are 16 results of throwing a coin 4 times.
Answer 4 first.
These are independent events. No matter what the first result or the second or the third result is outcome can only be 1/2 for any given throw. One event does not influence any other.
One
What this means is that it does not matter what else might be true as long as the second event is heads. So you count THTT and HHHH as both being true. If you use your table, I believe there are 8 results where heads is in the second position.
Two
The last position will also contain heats 8 times. Just count them up. Some of them will be duplicated from your first answer. It does not matter. For example, HHHH will appear in both lists.
Three
For Heads in the second AND the last position you should get 4. They are HHHH THHH THTH HHTH
Answers
P(one) = 8/16. You get 8 answers out of 16 to get a heads in position 2.
P(Two) = 8/16. You get 8 answers out of 16 to get a heads in position 4
P(Three) = 4/16. You get 4 answers out of 16 to get a heads in positions 2 and 4
