The answer to this question would be: B. JK and LM meet at a right angle.

The reversed T symbol in this question means "perpendicular". That means the JK and LM line have 90-degree angle difference. A straight angle is 180 degree and right angle mean 90 degrees.
A perpendicular line should be in the same plane and intersect each other.

A resistor utilized in a critical electronic component is required to have a resistance of 45 ohms /- 0.32 ohms. The current man

Lyrx [107]

Answer:

The value is $CP = 0.667$

Step-by-step explanation:

From the question we are told that

The resistance is $R = 45 \pm 0.32\ \Omega$

The mean is $\mu = 50 \Omega$

The standard deviation is $\sigma = 0.16 \Omega$

Generally the upper limit of the resistance specified in the question(i.e upper specification limit (USL )) is

$USL = 45 + 0.32 = 45.32 \ \Omega$

Generally the lower limit of the resistance specified in the question(i.e lower specification limit (USL )) is

$LSL = 45 - 0.32 = 44.68 \ \Omega$

Generally the CP of the process of manufacturing the resistor is mathematically represented as

$C P = \frac{ USL - LSL }{ 6 * \sigma }$

=> $CP = \frac{45.32 - 44.68 }{6 * 0.16}$

=> $CP = \frac{0.64 }{0.96}$

=> $CP = 0.667$

Mr. Kasse won 50% of the 60 tennis games he played one year. The next year, he won 80% of the 140 games he played. What percent

Lerok [7]

Answer:

72%

Step-by-step explanation:

50% of 60 = 30

80% of 140 = 112

112 + 30 = 142

142 is 72% of 200

john read the first 114 pages of a novel which is 3 pages less than 1/3 of the novel. write the equation

tatyana61 [14]

The equation is:

$114=\frac{p}{3}-3$

And

Total number of pages are 351

Step-by-step explanation:

The equation has to be formed by using the given information.

Let p be the total number of pages in the novel

Then

1/3rd of the p will pe:

$\frac{p}{3}$

Total pages read by John = 114

Then according to the statement

$114=\frac{p}{3}-3$

We can solve the equation to get the total pages of the novel

$114=\frac{p}{3}-3\\Adding\ 3\ on\ both\ sides\\114+3=\frac{p}{3}-3+3\\117=\frac{p}{3}\\Multiplying\ both\ sides\ by\ 3\\3*117 = \frac{p}{3}*3\\p=351$

The equation is:

$114=\frac{p}{3}-3$

And

Total number of pages are 351
