Answer: $x=\frac{-3}{k}$

Step-by-step explanation:

To solve for x, you need to get x alone. In this problem, k is a constant.

Quality control. As part of a quality control process for computer chips, an engineer at a factory randomly samples 212 chips du

Scrat [10]

Answer:

See Explanation

Step-by-step explanation:

According to the Question,

Given That, As part of a quality control process for computer chips, an engineer at a factory randomly samples 212 chips during a week of production to test the current rate of chips with severe defects. She finds that 27 of the chips are defective.

(a) The sample is from all computer chips manufactured at the factory during the week of production. We might be tempted to generalize the population to represent all weeks, but we should exercise caution here since the rate of defects may change over time.

(b) The fraction of computer chips manufactured at the factory during the week of production that had defects.

(d) Standard error (or SE).

(e) Compute the SE using phat = 0.127 in place of p:

SE ≈ √(phat(1−phat)/n) = 0.023.

(f) The standard error is the standard deviation of phat. A value of 0.10 would be about one standard error away from the observed value, which would not represent a very uncommon deviation. (Usually beyond about 2 standard errors is a good rule of thumb.) The engineer should not be surprised.

(g) Recomputed standard error using p = 0.1: SE = 0.021. This value isn't very different, which is typical when the standard error is computed using relatively similar proportions (and even sometimes when those proportions are quite different!).

Simplify. √20⋅√3·√18 5√30 5√10 6√10 6√30

ddd [48]

The correct answer is: [D]: " 6√30 " .

_____________________________________

Explanation:

_____________________________________

Simplify: " √20 ⋅ √3 · √18 " :

___________________________

Step 1) Simplify the "first term" :

"√20 " = √4 √5 = 2√5 ;

___________________________

Step 2): Consider the "second term:

"√3 " = √3 (already simplified);

___________________________

Step 3) Simplifly the "third term" :

" √18 " = √9 * √2 = " 3√2 " ;

____________________________

We have: " 2√5 * √3 * 3√2 " ;

= (2* 3) * (√5 * √3 * √2) ;

= 6 * (√5 √3 √2) ;

Note: " (√5 * √3 * √2 )" = " √(5 * 3 * 2) " = " √ 30 " .

So: " 6 * (√5 * √3 * √2) =

______________________________________

→ " 6 √30 " .

______________________________________

The answer is: " 6√30 " ;

→ which is: "Answer choice: [D]: " 6√30 " .

Hope this answer helps!

Best wishes!

Ada needs to make 140 egg tarts for the wedding. How many eggs should she buy from the store? Remember, her recipe makes 40 egg

just olya [345]

Answer:

Ada should buy 385 eggs from the store.

Step-by-step explanation:

Given that you know that Ada can make 40 egg tarts using 110 eggs, you can use a rule of three to find the amount eggs to make 140 egg tarts:

40 egg tarts → 110 eggs

140 egg tarts → x

x=(140*110)/40=385 eggs

According to this, the answer is that Ada should buy 385 eggs from the store.
