The probability that the first stage of a numerically controlled machining operation for high-rpm pistons meets specifications i

s 0.90. Failures are due to metal variations, fixture alignment, cutting blade condition, vibration, and ambient environmental conditions. Given that the first stage meets specifications, the probability that a second stage of machining meets specifications is 0.95. What is the probability that both stages meet specifications?

Answer:

There is an 85.5% probability that both stages meet specifications.

Step-by-step explanation:

We have these following probabilities:

A 90% probability that the first stage meets specifications.

If the first stage meets specifications, a 95% probability that the second stage also meets specifications.

What is the probability that both stages meet specifications?

This is the multiplication of these probabilities. So:

P = 0.9*0.95 = 0.855

There is an 85.5% probability that both stages meet specifications.

Marcus pours 12 ounces of cranberry juice into a punch bowl. He uses a container to add sprakling water to the bowl one ounce at
melomori [17]

Answer: There is 20 ounces of liquid in the bowl after adding 8 containers of sparkling water.

Step-by-step explanation:

Since we have given that

Number of ounces of cranberry juice into a punch bowl = 12 ounces

According to question, he uses a container to add sparkling water to the bowl one ounce at a time.

Let the amount of sparkling water added to the bowl be 'x'

Let the total number of ounces of liquid Marcus will have be 'y'.

So, our equation becomes,

y=12+x

Here, we have asked after adding 8 containers of sparkling water .

So, now, our equation becomes,

y=12+x\\\\y=12+8\\\\y=20\ ounces

Hence, there is 20 ounces of liquid in the bowl after adding 8 containers of sparkling water.

−7x−50≤−1 AND−6x+70>−2
fgiga [73]

Answer:

-7\geq x and [-7,12) in interval notation.

Step-by-step explanation:

We have been given a compound inequality -7x-50\leq -1\text{ and }-6x+70>-2. We are supposed to find the solution of our given inequality.

First of all, we will solve both inequalities separately, then we will combine both solution merging overlapping intervals.

-7x-50\leq -1

-7x-50+50\leq -1+50

-7x\leq 49

Dividing by negative number, flip the inequality sign:

\frac{-7x}{-7}\geq \frac{49}{-7}

x\geq -7

-6x+70>-2

-6x+70-70>-2-70

-6x>-72

Dividing by negative number, flip the inequality sign:

\frac{-6x}{-6}

x

Upon merging both intervals, we will get:

-7\geq x

Therefore, the solution for our given inequality would be -7\geq x and [-7,12) in interval notation.

A circular rug has a radius of 3 ft. What is the circumference of the rug? Use 3.14 for mc014-1.jpg.
Pavel [41]
Hello!

We must use a certain formula to find the circumference of anything circular.

The formula is:

C = 2 × pi × r

We know that pi = 3.14 approximately and the radius is 3 feet.

Substitute:

C = 2 × 3.14 × 3

C = 6.28 × 3

C = 18.84 ft

ANSWER:

The circumference of the circular rug is 18.84 ft. (Last option)
