Answer:

LXXXVII

Step-by-step explanation:

L=50 X=10 V=5 I=1

So basically you need to figure out what adds up to the 87. so use L, or 50. now XXX=30. so now you have 80 so we still have 7 left over, so we can write 7 I's or a 5, (V) and two I's. We should use the V and the I. So we take one V, or 5. and two I's which together is 7. which leads us too LXXXVII. also always remember to have the biggest number first, in this case the L (50).

Answer:

Jacob: 4
his mother: 39

Step-by-step explanation:

Let J and M represent the current ages of Jacob and his Mother.

<u>currently</u>:

M = 3 +9J

<u>in 11 years</u>:

M+11 = 5 +3(J+11)

Using the first equation to substitute for M in the second, we have ...

(3 +9J) +11 = 5 +3(J +11) . . . . . substitute for M

9J +14 = 3J +38 . . . . . . simplify

6J + 24 . . . . . . . . . . subtract 3J+14

J = 4 . . . . . . . . . . divide by 6

M = 3 +9(4) = 39

Jacob is 4 and his mother is 39.

Graph the line giving one point and the slope. 2x-6y=12

koban [17]

Y = mx + c

this is the equation of line and here m is the slope

so, 2x-6y =12 can be changed into standard format

y = 2x/6 - 12/6
y=x/3 +(-2)

so, m = 1/3 , so slope will be 1/3

hope it helped :)

Answer:

Step-by-step explanation:

As you need a 47%, you universe of numbers should be form 0 to 99 (or 1 to 100, the important fact is you need 100 numbers). With this, you can discard A and D. You can also discard C, as you need 47 good realizations as you probability is 47%, and C gives you 48 (00 also counts)

You need as many observations as you can, to get a more consistent estimation. This means, as many observations as you can. You could use B or E, because both have 47 good observations (for u), but E gives you a larger sample.

If you are trying to get a head with 50% throwing a dime, you will, statistically, do better throwing it 47 times than only 10 times.
