Answer:
1/8;17/20;But I don't really understand take them out separately or at the same time, the secondary answer is 17/180
Step-by-step explanation:
P1=5/40=1/8,that means there is 5 different balls in forty balls you can take,the situation you take the ball is 40,but the situation you take the different one is five so the possibility you take the different on is 5/40=1/8.
the next answer is just like how we do during the first question
A question like this should be answered by first looking at the number and the numbers you are given and making an estimate, testing it, and repeating if it is incorrect. It is relatively simple and I would like you to at least try a couple of times with an estimate of your own. If you really do have trouble with this, I will put the answers in a second. To make sure you understand the concept I will answer 3 of the 4 and you can try the last one. I will also just state the number of steps and leave the most of the expression writing to you. ;)
A. 8 feet forward, 8 feet forward. 8×2 or 0 + 8 + 8
B. Probably the hardest. Good thing you get to do it :)
C. 6 feet forward, 5 feet forward. 0 + 6+5 or 0 + 5+6 (This shows the commutative property)
D. 8 feet forward, 5 feet back. 0 + 8 - 5 or 0 - 5 + 8.
(You Don't Need the 0's in any of them unless you are showing the starting point which you probably are required to do, but since technically the Cecil starts at 0, added the 0 as the point at which to start your expression.)
Answer: B
Step-by-step explanation:
the parabola having (1,5) as vertex have as equation:
y=k*(x-1)²+5
It is passing through (2,8)
8=k*(2-1)²+5 ==> k+5=8 ==> k=3
equation is y=3(x-1)²+5
Answer B
.07Step-by-step explanation:
2xtimes 10 times 2
The model shows 7/10 which is equivalent to 70/100 (multiply top and bottom by 10).
