-43/204
Step-by-step explanation:
−5/12 × 17/17 + 7/34 × 6/6 =
= −85/204 + 42/204
= −85 + 42/204
= −43/204
Answer:
That probability is 0.1838 or 18.4% or enter 18.4
Step-by-step explanation:
mean 35 sd 5
20 is 3 sd s to the left of the mean
30 is 1 sd to the left.
The empirical rule has 68% within 1 sd or 34% on one side
It has 95% within 2 sd or 47.5% on one side
It has 99.7% within 3 sd or 49.85% on one side
Therefore between 3 sd and 1 sd on one side is 49.85-34=15.85% or enter 15.9
mean of 48 sd 7
between 48 and 55 is between -1 and 0 sd or 34% enter 34. The last one doesn't seem to post easily:z=(x-mean)/sd or z< (1217-1481)/293 or z <-264/293 or -0.901,
That probability is 0.1838 or 18.4% or enter 18.4
KU and UM are equal to each other.
KU = 3x + 3
UM = 4x - 4
3x + 3 = 4x - 4
3x = 4x - 7
-x = -7
x = 7
If you plug that into either one of the equations, you get 24.
3(7) + 3
24
So depending on your question, x is 7, KU is 24, and UM is 24.
Here are the steps. I hope I do them easy enough for you to understand it
-3/4+1/8
=-3/4+1/8
=-6/8+1/8
=6+1
-------
8
And the answer is -5/8 (The decimal is -0.625)
I hoped I helped :)
