Answers

If y = 4x then you'd input that information into your equation making: 3x-4x = 1
The correct solution is: 3(-1)-4(-1) = 1

y = 4x .....(a)

3x - y = 1. ......(b)

Substitute y = 4x in (a) into (b)

3x - y = 1......(b)

3x - 4x = 1

-x = 1

x = -1

Recall, y = 4x ........(a)

y = 4*(-1)

y = -4.

Therefore, x = -1, and y = -4.

Answer:

Step-by-step explanation:

An orbiting satellite has seven solar cells, which function independently of each other. During a mission, each cell fails with a probability of 0.3. What is the probability that there will be adequate power output for the mission if 7. All 7 cells must be active?

Answers

The probability of each cell not failing is 1.0 - 0.3 = 0.7.
The probability of all 7 cells not failing during a mission is given by:
$P(7\ cells\ do\ not\ fail)=0.7^(7)=0.082\ or\ 8.2\ percent$

Final answer:

The probability that all 7 solar cells will be active is 0.08243, or approximately 8.24%.

Explanation:

In this question, we are given that each solar cell on the satellite has a failure probability of 0.3. Since there are 7 cells, we need all of them to be active in order to have adequate power output for the mission. To find the probability of this happening, we need to calculate the probability of all 7 cells being active.

Since each cell operates independently, the probability of a cell failing is 0.3 and the probability of it being active is 1 - 0.3 = 0.7. Therefore, the probability that all 7 cells will be active is (0.7)^7 = 0.08243.

Thus, the probability of there being adequate power output for the mission is 0.08243, or approximately 8.24%.
