Answer:

C=P/4-a/2-3b/4

Step-by-step explanation:

Question: P=2a+3b+4c

1) Subtract 2a and 3b from both sides:

P-2a-3b=4C

2) Divide everything by 4:

C=P/4-2a/4-3b/4

3) Simplify 2a/4: <u>(a/2)</u>

C=P/4-a/2-3b/4

Answer:

(P-2a-3b)/4=c

Step-by-step explanation:

First, isolate the variable we are solving for, c (P-2a-3b=4c). Now, divide by 4 to get c completely alone ((P-2a-3b)/4=c).

A sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's p
charle [14.2K]

Answer:

So the value of the test statistic is -0.85.

Step-by-step explanation:

We know that a sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 54% of the chips do not fail in the first 1000 hours of their use.

We get that:

n=1800\\\\p_1=53\%=0.53\\\\p_2=54\%=0.54\\

We calculate the standar deviation:

\sigma=\sqrt{\frac{0.53 \cdot (1-0.53)}{n}}=\sqrt{\frac{0.53 \cdot 0.47}{1800}}=0.01176

We calculate the value of the test statistic:

z=\frac{p_1-p_2}{\sigma}=\frac{0.53-0.54}{0.01176}=-0.85

So the value of the test statistic is -0.85.

Inessa05 [86]

Considering the withdraws and credits, Lucia's current available balance is of $65.53.

<h3>How do we find a balance?</h3>

It is given by the sum of the money that the people has with the pending credits, and subtracted by the pending withdraws.

In this problem, we have that:

  • Lucia has $412.76, with pending credits of $134.00.
  • She has pending withdraws of $481.23.

Hence, her avaiable balance is given by:

412.76 + 134 - 481.23 = $65.53.
