Answer:

XZ = 12x + 6

Step-by-step explanation:

XZ = XY + YZ

XZ = <u>4x</u> + 7 + <u>8x</u> - 1

XZ = 12x + 6

If the label of a can of yams were cut off and laid flat, which expression would give the area, A, of the label with the measure
Damm [24]
I think you are missing information to solve this problem.  Should there me an image attached to this question.

Either way, to solve for the label, the label would most likely me a rectangle when laid flat.

It's dimensions would be length x height.

Where height is most likely "h"
and
length is most likely the circumference (2πr)

Thus the possible answers are either:

B or C

I can't answer it until I see an image when more detail.

Hope this helps!

Find each measure cause i don't understand?
vekshin1

Answer:

x=6 .  m<PQS=82  m<SQR=61 :)

Step-by-step explanation:

(13x+4) + (10x-1) = 141

combine like terms

23x+3=141

subtract 3 from both sides

23x=138

divide both sides by 23

x=6

substitute x into both original equations

m<PQS=13(6)+4

m<PQS=78+4

m<PQS= 82

m<SQR=10(6)+1

m<SQR=60+1

M<SQR=61

The function y=ex is vertically stretched by a factor of 2, reflected across the x-axis, and then shifted down 3 units, find the
Anettt [7]

Answer:

y = - 2 e^{x} - 3

Step-by-step explanation:

We have to vertically stretch the function y = e^{x} by a factor of 2.

Then the function will become y = 2e^{x}.

Then it is reflected across the x-axis.

So, the new function will be y = - 2e^{x}.

Now, if the function is shifted down 3 units then the final function will become y = - 2 e^{x} - 3 (Answer)

In a semiconductor manufacturing process, three wafers from a lot are tested. Each wafer is classified as pass or fail. Assume t
Angelina_Jolie [31]

Answer:

P(X = 0) = 0.027

P(X = 1) = 0.189

P(X = 2) = 0.441

P(X = 3)= 0.343

Step-by-step explanation:

The probability mass function P(X = x) is the probability that X happens x times.

When n trials happen, for each x \leq n, the probability mass function is given by:

P(X = x) = pe_{n,x}.p^{x}.(1-p)^{n-x}

In which p is the probability that the event happens.

pe_{n,x}, is the permutation of n elements with x repetitions(when there are multiple events happening(like one passes and two not passing)). It can be calculated by the following formula:

pe_{n,x} = \frac{n!}{x!}

The sum of all P(X=x) must be 1.

In this problem

We have 3 trials, so n = 3

The probability that a wafer pass a test is 0.7, so p = 0.7

Determine the probability mass function of the number of wafers from a lot that pass the test.

P(X = 0) = (0.7)^{0}.(0.3)^{3} = 0.027

P(X = 1) = pe_{3,1}.(0.7).(0.3)^{2} = 0.189

P(X = 2) = pe_{3,2}.(0.7)^{2}.(0.3) = 0.441

P(X = 3) = (0.7)^{3} = 0.343
