solve the following and explain your steps. Leave your answer in base-exponent form. (3^-2*4^-5*5^0)^-3(4^-4 over 3^3)*3^3 Pleas

Jobisdone [24]

Answer:

$3^64^{11}$

Step-by-step explanation:

It appears you're trying to simplify ...

$(3^{-2}4^{-5}5^0)^{-3}\cdot\dfrac{4^{-4}}{3^3}\cdot 3^3$

The final factor cancels the denominator of the fraction, so we have ...

$3^{(-2)(-3)}4^{(-5)(-3)-4}=3^64^{11}$

_____

The applicable rules of exponents are ...

(ab)^c = (a^c)(b^c)

(a^b)(a^c) = a^(b+c)

(a^b)^c = a^(bc)

Goranson and Hall (1980) explain that the probability of detecting a crack in an airplane wing is the product of p1, the probabi

PolarNik [594]

Answer:

a. The multiplication of these probabilities is justified because the inspections are isolated or don't have the same goal. For instance p1, would mean that not all the planes are checked, p2 that not all the parts in the plane are checked, and p3, that even if the the part where the crack could be inspected, people checking it could not notice it or it could be not identified easily.

b. As the events are independent and there are only two possible answers (detect the plane or not), a binomial distribution could be applied, therefore:

p=0.9*0.8*.5=36 (probability of detecting the crack)

n=3 (number of possibilities, in this case number of planes)

The probability in a binomial formula is given by

$P(X=x)=\frac{n!}{(n-x)!x!}*p^{x}*(1-p)^{n-x}$

Considering that the only possibility that is not being asked is the one of not detecting any crack which would mean x=0, then, we could find the probability as

$P(X\geq 1)$ =1- $P(X=0)$

$P(X\geq 1)=1-P(X=0)=1-\frac{3!}{3!0!} *0.36^{0} *0.64^{3} =0.737856$

Probability is then 0.737856

A group of students is arranging squares into layers to create a project. The first layer has 6 squares. The second layer has 12

kkurt [141]

Answer:

$a_n=6n$

Step-by-step explanation:

This is an example of an arithmetic sequence that is that the following term is obtained by adding or substracting a number called difference the formula for this sequence is:

$a_n=a_1+d(n-1)$

In this case your first term is:

$a_1=6$

and your difference is

$d=6$

substituting these values we have that

$a_{n}=6+6(n-1) \\a_n=6+6n-6\\a_n=6n$

Which ordered pairs is a solution to 5x+3y>12 Question 2 options: (3, 9) (-5, 5) (3, -6) (-2, -5) (2, 8) (-6, 0)

jek_recluse [69]

The solution to the expression given as 5x + 3y > 12 has the ordered pair of (3, 0)

<h3>How to determine the ordered pair of the solution?</h3>

From the question, we have the following inequality that can be used in our computation:

5x + 3y > 12

Solving further, we need to collect the like terms

So, the expression becomes

3y > 12 - 5x

Next, we divide through the inequality by 3

So, we have the following representation

y > 12/3 - 5/3x

Evaluate

The equation becomes

y > 4 - 5/3x

At this point, we assume any value for x and then solve for y

Assume that the value of x is 3

So, we have the following representation

y > 4 - 5/3 * 3

Evaluate the products

y > -1

A value greater than -1 is 0

So, we have

x = 3 and y = 0

Express as ordered pairs

(x, y) = (3, 0)

Hence, the ordered pair of the solution is (3, 0)
