5*4=20 and 20+5=25 the answer is 4 :)
yes, tysm! :)
I think you just take your two points and find the absolute value of b-a, a and b being your two points... so, if 2 1/2 = a and 5 3/4 = b and d= distance d= |b-a| d= |5 3/4 - 2 1/2| d= 3 1/4
Ohhhh I just over thought this way too much.. thank you!!
Yes tysm! :)
(Problem a) The events are dependent because you're looking for a specific product. (Problem b) Now, assuming that the cubes have six faces: P(blue is less than 3)= 2/6 = 1/3 The product is 8; 1*8=8, but there is no 8 on a die. So blue must be 2 and yellow
No Problem!
The events are independent, so event A would be multiplied by event B. (Event A =rolling an even #) (Event B =rolling a 6). The probability of event A = 1/2 The probability of event B = 1/6 To solve: P(even then 6)= 1/2*1/6 = 1/12 = 0.083 Therefore, there
Thank you!
Well, an algebraic open equation (also known as an open sentence) is a mathematical equation that is neither true nor false. so an example of an open equation could be x + 3 = 7 or 2x = 12. Hope this helps with #5 :D
