Answer:

When we are dividing exponents, there is this rule:

$\frac{a^n}{a^m}=a^{(n-m)}$

So, in our case we have this:

$\frac{16a^5b^3}{8ab} = \frac{16}{8}a^{(5-1)}b^{(3-1)}$ $=2a^4b^2$

We ask the engineers working on activity A to factor in uncertainty in activity times and to provide better estimates of the act

babymother [125]

Answer:

On average, the project takes 4 weeks to complete.

Step-by-step explanation:

We have these following probabilities:

25% probability that the activity takes 2 weeks.

50% probability that the activity takes 4 weeks.

25% probability that the activity takes 6 weeks.

How long does the project now take to complete (on average)

We multiply each duration by it's probability.

0.25*2 + 0.5*4 + 0.25*6 = 4

On average, the project takes 4 weeks to complete.

Point Q(-2, 8) is translated using the rule (x + 1, y - 2).

insens350 [35]

The coordinate notation is (x,y)---- >(x+1,y-2)

Q(-2, 8)

only y coordinate is (y)--------------- > ( y-2)
therefore
(8)------------------------------------ >(8-2)=(6)
the y coordinate of Q' is 6

3 + 1/3 equals b - 23 State the problem

Viefleur [7K]

Answer:

$b=\frac{79}{3}$ or $b=26.33$

Step-by-step explanation:

Assuming the question to be finding the value of b.

$3+\frac{1}{3}=b-23$

Solution:

Rewrite the equation as.

$b-23=3+\frac{1}{3}$

first we solve right side of the equation.

$b-23=\frac{3\times 3+ 1}{3}$

$b-23=\frac{9+ 1}{3}$

$b-23=\frac{10}{3}$

Add 23 both side of the equation.

$b-23+23=\frac{10}{3}+23$

$b=\frac{10+23\times 3}{3}$

$b=\frac{10+69}{3}$

$b=\frac{79}{3}$

$b=26.33$

Therefore, the value of $b=\frac{79}{3}$ or $b=26.33$
