Answer:
Step-by-step explanation:
So, our equation is:
In exponetial form, this looks like:
Now lets cube the 5:
Next, we can multiply the denominator on the right side by 5:
We need to now get x alone by adding 4 to both sides:
Finally, we divide by x's coefficent, 2, to get:
Hope this helps! :3
Answer:
Step-by-step explanation:
Distance=400+200=600km
diplacement=x 200-0km=200km
total distance travelled=400+400=800km
<span>P(1 claim) = p/4
P(2 claims) = (p/4)/4 = p/16
You should see that the distribution follows a geometric series with common ratio 1/4.
Sum geometric = (first term) / (1 - common ratio) = p/(1 - 1/4) = 4p/3
But the sum of all the probabilites must equal 1 ----> 4p/3 = 1 ----> p = 3/4
P(2 or more claims) = 1 - P(0 claims) - P(1 claim) = 1 - 3/4 - 3/16 = 1/16</span>
Chance of boy: 627/1,358
Chance of girl: 731/1,358
first we need to get rid of the ( ) so that we can see what the question really says
(3x³-5x² - 7+ 4x4) + (9x4 - 10x² - 5x³ + 3)
= 3x³-5x²-7+4x⁴+9x⁴-10x²-5x³+3
now all we need to do is add up the numbers with the same x's
<em>3x³</em>-5x²-7<u>+4x⁴+9x⁴</u>-10x²<em>-5x³</em>+3
= 13x⁴-2x³-15x²-4
