Answer:

\Huge \boxed{(x+1)^3}

Step-by-step explanation:

x³ + 3x² + 3x + 1

Apply cube of sum rule :

      ⇒ a³ + 3a²b + 3ab² + b³ = (a + b)³

(x)³ + 3(x)²(1) + 3(x)(1)² + (1)³

 ⇒ a = x

 ⇒ b = 1

(x + 1)³

PLSS HELPP<br><br> Probability statistics
Lisa [10]

So okay, in stats when there is probability that looks like p(fem/type b) it means what is the probability that they are female given they are type b, so it would be where they intersect. Therefore where they intersect on the table is 22 out of the total of 200 people so 1/10. Now that we know that probability let's look at the "or" one, when it says or it means it could be a female or a type b so we would include both totals of each:

97 females+70 type b= 167

now we divide that by the total amount of people so it simplifies down to a probability of 0.835.

Finally, looking at these 2 probability we can see that the "or" probability is far greater than the one previous discussed so it would be the last option if I remeber correctly!!

How do you solve this equation?<br>step by step...<br>-9(x-9)=252
katovenus [111]
Well think about it this way -9 times what equals 252 you already know x is going to be a negative number because the outcome is positive so try doing the problem backwards 252/-9=-28 so x=-28

0.48 miles

Step-by-step explanation:

Step 1

It is given that the grade(slope) is 4%. This means that for every 100 miles traveled, the elevation changes by 4 miles.

Step 2

Hence for a distance of 12 miles , the elevation changes by 12*4/100 = 48/100 = 0.48 miles. [Using direct proportion]
