Answer:
x=2, mn=ol=7
Step-by-step explanation:
by definition of a parallelogram we can see that the 2 lines are equal and therefore x+5=2x+3 which we can solve and get x=2. We can put the x=2 back into either line to solve since the 2 lines have equal length. Done!
Answer:
Step-by-step explanation:
Given that
A sample space consists of five simple events, E1, E2, E3, E4, and E5.
a If P(E1) = P(E2) = 0.15,
P(E3) = 0.4, and P(E4) = 2P(E5),
We know that total probability =1
i.e. sum of probabilities of All Eis would be 1
where x = P(E5)
Solving for x we get
x=0.30
So P(E4) = 0.2 and P(E5) = 0.1
-----
b) Let P(E3) =P(E4) = P(E5) = y
then we have
total probability = 
Probability of remain are 0.2 each.
Answer:
n=7 d=8
Step-by-step explanation:
n+d=15 d=15-n
0.05n+0.1(15-n)=1.15
0.05n-0.1n+1.5=1.15
-0.05n=-0.35
n=7 d=8
Answer:
1) -15/32
2) 2/15
3) -203.5
4) -3/2 = -1.5
5) 10/3 = 3 1/3
Step-by-step explanation:
For 1, you just multiply the numerators and denominators together (3 by 5, 4 by 8) and then because it is negative, add the negative sign.
For 2, you multiply again, but because there are 2 negative signs, it becomes positive.
For 3, you divide 81.4 by 0.4, you could also divide 814 by 4.
For 4, you keep change flip, so the equation would become -9/4 (-2 1/4=-9/4) and 3/2 would become 2/3. The equation would be (-9/4 * 2/3). Then, you would get -18/12 which is -3/2.
For 5, you just multiply 4/3 by 5/2 which is 20/6 and because 2 negatives, it becomes positive.
