2-23 Ace Machine Works estimates that the probability its lathe tool is properly adjusted is 0.8. When the lathe is properly adjusted, there is a 0.9 probability that the parts produced pass inspection. If the lathe is out of adjustment, however, the probability of a good part being produced is only 0.2. A part randomly chosen is inspected and found to be acceptable. At this point, what is the posterior probability that the lathe tool is properly adjusted?

The inscribed angle theorem says that the angle formed by two intersecting chords of a circle (the angle A between the chords AC and AB in this case) has half the measure of the central angle subtended by the arc containing those chords (arc CB in this case). So

$m\angle BAC=\frac12m\angle BFC\implies m\angle BFC=2\cdot35^\circ=70^\circ$

A penny, a nickel, a dime, and a quarter are tossed. What is the probability of obtaining at least three tails on the losses

Answers

Answer:

1/8th chance

Step-by-step explanation:

two outcomes per toss, H and T, so 1/2 probability of getting tails

0.5*0.5*0.5 = 1/8th chance

One type of insect is 0.0052 meter long. what is the length in scientific notation.

Answers

Here, we need to write the length of the insect in scientific notation.

The given length of the insect is 0.0052 meter

Now, to write 0.0052 meter in scientific notation we need to follow this:

Scientific notation always start with non-zero digit followed by a decimal point.

Since in our number the decimal is needed to be moved three places to the right to get the first non-zero digit.

The exponent of the 10 is $-3$ .

$10^(-3)=(1)/(1000) =0.001$

Therefore, our number 0.0052 can be written as:

$5.2 * 10^(-3)$

Hence, the require scientific notation is $5.2 * 10^(-3)$ .

Step-by-step explanation:

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle. Step 1: m∠m + m∠n + m∠o = 180 degrees (sum of angles of a triangle)

Step 2: m∠p − m∠o = 90 degrees (alternate interior angles)

Step 3: Therefore, m∠m + m∠n + m∠o = m∠o + m∠p

Step 4: So, m∠m + m∠n = m∠p

In which step did the student first make a mistake and how can it be corrected?

1.) Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (corresponding angles)

2.) Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)

3.) Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)

4.) Step 2; it should be m∠o + m∠p = 180 degrees (supplementary angles)
